fix: make devcontainer ID fields optional in proto schema

- Change id and subagent_id from required to optional bytes
- Remove inline comments from proto file per code review
- Revert TypeScript type assertion workarounds (no longer needed)

The optional keyword makes these fields truly optional in proto3,
which fixes TypeScript type compatibility without requiring unsafe
type assertions.

+# Coder Architecture
+
+This document provides an overview of Coder's architecture and core systems.
+
+## What is Coder?
+
+Coder is a platform for creating, managing, and using remote development environments (also known as Cloud Development Environments or CDEs). It leverages Terraform to define and provision these environments, which are referred to as "workspaces" within the project. The system is designed to be extensible, secure, and provide developers with a seamless remote development experience.
+
+## Core Architecture
+
+The heart of Coder is a control plane that orchestrates the creation and management of workspaces. This control plane interacts with separate Provisioner processes over gRPC to handle workspace builds. The Provisioners consume workspace definitions and use Terraform to create the actual infrastructure.
+
+The CLI package serves dual purposes - it can be used to launch the control plane itself and also provides client functionality for users to interact with an existing control plane instance. All user-facing frontend code is developed in TypeScript using React and lives in the `site/` directory.
+
+The database layer uses PostgreSQL with SQLC for generating type-safe database code. Database migrations are carefully managed to ensure both forward and backward compatibility through paired `.up.sql` and `.down.sql` files.
+
+## API Design
+
+Coder's API architecture combines REST and gRPC approaches. The REST API is defined in `coderd/coderd.go` and uses Chi for HTTP routing. This provides the primary interface for the frontend and external integrations.
+
+Internal communication with Provisioners occurs over gRPC, with service definitions maintained in `.proto` files. This separation allows for efficient binary communication with the components responsible for infrastructure management while providing a standard REST interface for human-facing applications.
+
+## Network Architecture
+
+Coder implements a secure networking layer based on Tailscale's Wireguard implementation. The `tailnet` package provides connectivity between workspace agents and clients through DERP (Designated Encrypted Relay for Packets) servers when direct connections aren't possible. This creates a secure overlay network allowing access to workspaces regardless of network topology, firewalls, or NAT configurations.
+
+### Tailnet and DERP System
+
+The networking system has three key components:
+
+1. **Tailnet**: An overlay network implemented in the `tailnet` package that provides secure, end-to-end encrypted connections between clients, the Coder server, and workspace agents.
+
+2. **DERP Servers**: These relay traffic when direct connections aren't possible. Coder provides several options:
+   - A built-in DERP server that runs on the Coder control plane
+   - Integration with Tailscale's global DERP infrastructure
+   - Support for custom DERP servers for lower latency or offline deployments
+
+3. **Direct Connections**: When possible, the system establishes peer-to-peer connections between clients and workspaces using STUN for NAT traversal. This requires both endpoints to send UDP traffic on ephemeral ports.
+
+### Workspace Proxies
+
+Workspace proxies (in the Enterprise edition) provide regional relay points for browser-based connections, reducing latency for geo-distributed teams. Key characteristics:
+
+- Deployed as independent servers that authenticate with the Coder control plane
+- Relay connections for SSH, workspace apps, port forwarding, and web terminals
+- Do not make direct database connections
+- Managed through the `coder wsproxy` commands
+- Implemented primarily in the `enterprise/wsproxy/` package
+
+## Agent System
+
+The workspace agent runs within each provisioned workspace and provides core functionality including:
+
+- SSH access to workspaces via the `agentssh` package
+- Port forwarding
+- Terminal connectivity via the `pty` package for pseudo-terminal support
+- Application serving
+- Healthcheck monitoring
+- Resource usage reporting
+
+Agents communicate with the control plane using the tailnet system and authenticate using secure tokens.
+
+## Workspace Applications
+
+Workspace applications (or "apps") provide browser-based access to services running within workspaces. The system supports:
+
+- HTTP(S) and WebSocket connections
+- Path-based or subdomain-based access URLs
+- Health checks to monitor application availability
+- Different sharing levels (owner-only, authenticated users, or public)
+- Custom icons and display settings
+
+The implementation is primarily in the `coderd/workspaceapps/` directory with components for URL generation, proxying connections, and managing application state.
+
+## Implementation Details
+
+The project structure separates frontend and backend concerns. React components and pages are organized in the `site/src/` directory, with Jest used for testing. The backend is primarily written in Go, with a strong emphasis on error handling patterns and test coverage.
+
+Database interactions are carefully managed through migrations in `coderd/database/migrations/` and queries in `coderd/database/queries/`. All new queries require proper database authorization (dbauthz) implementation to ensure that only users with appropriate permissions can access specific resources.
+
+## Authorization System
+
+The database authorization (dbauthz) system enforces fine-grained access control across all database operations. It uses role-based access control (RBAC) to validate user permissions before executing database operations. The `dbauthz` package wraps the database store and performs authorization checks before returning data. All database operations must pass through this layer to ensure security.
+
+## Testing Framework
+
+The codebase has a comprehensive testing approach with several key components:
+
+1. **Parallel Testing**: All tests must use `t.Parallel()` to run concurrently, which improves test suite performance and helps identify race conditions.
+
+2. **coderdtest Package**: This package in `coderd/coderdtest/` provides utilities for creating test instances of the Coder server, setting up test users and workspaces, and mocking external components.
+
+3. **Integration Tests**: Tests often span multiple components to verify system behavior, such as template creation, workspace provisioning, and agent connectivity.
+
+4. **Enterprise Testing**: Enterprise features have dedicated test utilities in the `coderdenttest` package.
+
+## Open Source and Enterprise Components
+
+The repository contains both open source and enterprise components:
+
+- Enterprise code lives primarily in the `enterprise/` directory
+- Enterprise features focus on governance, scalability (high availability), and advanced deployment options like workspace proxies
+- The boundary between open source and enterprise is managed through a licensing system
+- The same core codebase supports both editions, with enterprise features conditionally enabled
+
+## Development Philosophy
+
+Coder emphasizes clear error handling, with specific patterns required:
+
+- Concise error messages that avoid phrases like "failed to"
+- Wrapping errors with `%w` to maintain error chains
+- Using sentinel errors with the "err" prefix (e.g., `errNotFound`)
+
+All tests should run in parallel using `t.Parallel()` to ensure efficient testing and expose potential race conditions. The codebase is rigorously linted with golangci-lint to maintain consistent code quality.
+
+Git contributions follow a standard format with commit messages structured as `type: <message>`, where type is one of `feat`, `fix`, or `chore`.
+
+## Development Workflow
+
+Development can be initiated using `scripts/develop.sh` to start the application after making changes. Database schema updates should be performed through the migration system using `create_migration.sh <name>` to generate migration files, with each `.up.sql` migration paired with a corresponding `.down.sql` that properly reverts all changes.
+
+If the development database gets into a bad state, it can be completely reset by removing the PostgreSQL data directory with `rm -rf .coderv2/postgres`. This will destroy all data in the development database, requiring you to recreate any test users, templates, or workspaces after restarting the application.
+
+Code generation for the database layer uses `coderd/database/generate.sh`, and developers should refer to `sqlc.yaml` for the appropriate style and patterns to follow when creating new queries or tables.
+
+The focus should always be on maintaining security through proper database authorization, clean error handling, and comprehensive test coverage to ensure the platform remains robust and reliable.

+# Documentation Style Guide
+
+This guide documents documentation patterns observed in the Coder repository, based on analysis of existing admin guides, tutorials, and reference documentation. This is specifically for documentation files in the `docs/` directory - see [CONTRIBUTING.md](../../docs/about/contributing/CONTRIBUTING.md) for general contribution guidelines.
+
+## Research Before Writing
+
+Before documenting a feature:
+
+1. **Research similar documentation** - Read recent documentation pages in `docs/` to understand writing style, structure, and conventions for your content type (admin guides, tutorials, reference docs, etc.)
+2. **Read the code implementation** - Check backend endpoints, frontend components, database queries
+3. **Verify permissions model** - Look up RBAC actions in `coderd/rbac/` (e.g., `view_insights` for Template Insights)
+4. **Check UI thresholds and defaults** - Review frontend code for color thresholds, time intervals, display logic
+5. **Cross-reference with tests** - Test files document expected behavior and edge cases
+6. **Verify API endpoints** - Check `coderd/coderd.go` for route registration
+
+### Code Verification Checklist
+
+When documenting features, always verify these implementation details:
+
+- Read handler implementation in `coderd/`
+- Check permission requirements in `coderd/rbac/`
+- Review frontend components in `site/src/pages/` or `site/src/modules/`
+- Verify display thresholds and intervals (e.g., color codes, time defaults)
+- Confirm API endpoint paths and parameters
+- Check for server flags in serpent configuration
+
+## Document Structure
+
+### Title and Introduction Pattern
+
+**H1 heading**: Single clear title without prefix
+
+```markdown
+# Template Insights
+```
+
+**Introduction**: 1-2 sentences describing what the feature does, concise and actionable
+
+```markdown
+Template Insights provides detailed analytics and usage metrics for your Coder templates.
+```
+
+### Premium Feature Callout
+
+For Premium-only features, add `(Premium)` suffix to the H1 heading. The documentation system automatically links these to premium pricing information. You should also add a premium badge in the `docs/manifest.json` file with `"state": ["premium"]`.
+
+```markdown
+# Template Insights (Premium)
+```
+
+### Overview Section Pattern
+
+Common pattern after introduction:
+
+```markdown
+## Overview
+
+Template Insights offers visibility into:
+
+- **Active Users**: Track the number of users actively using workspaces
+- **Application Usage**: See which applications users are accessing
+```
+
+Use bold labels for capabilities, provides high-level understanding before details.
+
+## Image Usage
+
+### Placement and Format
+
+**Place images after descriptive text**, then add caption:
+
+```markdown
+![Template Insights page](../../images/admin/templates/template-insights.png)
+
+<small>Template Insights showing weekly active users and connection latency metrics.</small>
+```
+
+- Image format: `![Descriptive alt text](../../path/to/image.png)`
+- Caption: Use `<small>` tag below images
+- Alt text: Describe what's shown, not just repeat heading
+
+### Image-Driven Documentation
+
+When you have multiple screenshots showing different aspects of a feature:
+
+1. **Structure sections around images** - Each major screenshot gets its own section
+2. **Describe what's visible** - Reference specific UI elements, data values shown in the screenshot
+3. **Flow naturally** - Let screenshots guide the reader through the feature
+
+**Example**: Template Insights documentation has 3 screenshots that define the 3 main content sections.
+
+### Screenshot Guidelines
+
+**When screenshots are not yet available**: If you're documenting a feature before screenshots exist, you can use image placeholders with descriptive alt text and ask the user to provide screenshots:
+
+```markdown
+![Placeholder: Template Insights page showing weekly active users chart](../../images/admin/templates/template-insights.png)
+```
+
+Then ask: "Could you provide a screenshot of the Template Insights page? I've added a placeholder at [location]."
+
+**When documenting with screenshots**:
+
+- Illustrate features being discussed in preceding text
+- Show actual UI/data, not abstract concepts
+- Reference specific values shown when explaining features
+- Organize documentation around key screenshots
+
+## Content Organization
+
+### Section Hierarchy
+
+1. **H2 (##)**: Major sections - "Overview", "Accessing [Feature]", "Use Cases"
+2. **H3 (###)**: Subsections within major sections
+3. **H4 (####)**: Rare, only for deeply nested content
+
+### Common Section Patterns
+
+- **Accessing [Feature]**: How to navigate to/use the feature
+- **Use Cases**: Practical applications
+- **Permissions**: Access control information
+- **API Access**: Programmatic access details
+- **Related Documentation**: Links to related content
+
+### Lists and Callouts
+
+- **Unordered lists**: Non-sequential items, features, capabilities
+- **Ordered lists**: Step-by-step instructions
+- **Tables**: Comparing options, showing permissions, listing parameters
+- **Callouts**:
+  - `> [!NOTE]` for additional information
+  - `> [!WARNING]` for important warnings
+  - `> [!TIP]` for helpful tips
+- **Tabs**: Use tabs for presenting related but parallel content, such as different installation methods or platform-specific instructions. Tabs work well when readers need to choose one path that applies to their specific situation.
+
+## Writing Style
+
+### Tone and Voice
+
+- **Direct and concise**: Avoid unnecessary words
+- **Active voice**: "Template Insights tracks users" not "Users are tracked"
+- **Present tense**: "The chart displays..." not "The chart will display..."
+- **Second person**: "You can view..." for instructions
+
+### Terminology
+
+- **Consistent terms**: Use same term throughout (e.g., "workspace" not "workspace environment")
+- **Bold for UI elements**: "Navigate to the **Templates** page"
+- **Code formatting**: Use backticks for commands, file paths, code
+  - Inline: `` `coder server` ``
+  - Blocks: Use triple backticks with language identifier
+
+### Instructions
+
+- **Numbered lists** for sequential steps
+- **Start with verb**: "Navigate to", "Click", "Select", "Run"
+- **Be specific**: Include exact button/menu names in bold
+
+## Code Examples
+
+### Command Examples
+
+````markdown
+```sh
+coder server --disable-template-insights
+```
+````
+
+### Environment Variables
+
+````markdown
+```sh
+CODER_DISABLE_TEMPLATE_INSIGHTS=true
+```
+````
+
+### Code Comments
+
+- Keep minimal
+- Explain non-obvious parameters
+- Use `# Comment` for shell, `// Comment` for other languages
+
+## Links and References
+
+### Internal Links
+
+Use relative paths from current file location:
+
+- `[Template Permissions](./template-permissions.md)`
+- `[API documentation](../../reference/api/insights.md)`
+
+For cross-linking to Coder registry templates or other external Coder resources, reference the appropriate registry URLs.
+
+### Cross-References
+
+- Link to related documentation at the end
+- Use descriptive text: "Learn about [template access control](./template-permissions.md)"
+- Not just: "[Click here](./template-permissions.md)"
+
+### API References
+
+Link to specific endpoints:
+
+```markdown
+- `/api/v2/insights/templates` - Template usage metrics
+```
+
+## Accuracy Standards
+
+### Specific Numbers Matter
+
+Document exact values from code:
+
+- **Thresholds**: "green < 150ms, yellow 150-300ms, red ≥300ms"
+- **Time intervals**: "daily for templates < 5 weeks old, weekly for 5+ weeks"
+- **Counts and limits**: Use precise numbers, not approximations
+
+### Permission Actions
+
+- Use exact RBAC action names from code (e.g., `view_insights` not "view insights")
+- Reference permission system correctly (`template:view_insights` scope)
+- Specify which roles have permissions by default
+
+### API Endpoints
+
+- Use full, correct paths (e.g., `/api/v2/insights/templates` not `/insights/templates`)
+- Link to generated API documentation in `docs/reference/api/`
+
+## Documentation Manifest
+
+**CRITICAL**: All documentation pages must be added to `docs/manifest.json` to appear in navigation. Read the manifest file to understand the structure and find the appropriate section for your documentation. Place new pages in logical sections matching the existing hierarchy.
+
+## Proactive Documentation
+
+When documenting features that depend on upcoming PRs:
+
+1. **Reference the PR explicitly** - Mention PR number and what it adds
+2. **Document the feature anyway** - Write as if feature exists
+3. **Link to auto-generated docs** - Point to CLI reference sections that will be created
+4. **Update PR description** - Note documentation is included proactively
+
+**Example**: Template Insights docs include `--disable-template-insights` flag from PR #20940 before it merged, with link to `../../reference/cli/server.md#--disable-template-insights` that will exist when the PR lands.
+
+## Special Sections
+
+### Troubleshooting
+
+- **H3 subheadings** for each issue
+- Format: Issue description followed by solution steps
+
+### Prerequisites
+
+- Bullet or numbered list
+- Include version requirements, dependencies, permissions
+
+## Formatting and Linting
+
+**Always run these commands before submitting documentation:**
+
+```sh
+make fmt/markdown   # Format markdown tables and content
+make lint/markdown  # Lint and fix markdown issues
+```
+
+These ensure consistent formatting and catch common documentation errors.
+
+## Formatting Conventions
+
+### Text Formatting
+
+- **Bold** (`**text**`): UI elements, important concepts, labels
+- *Italic* (`*text*`): Rare, mainly for emphasis
+- `Code` (`` `text` ``): Commands, file paths, parameter names
+
+### Tables
+
+- Use for comparing options, listing parameters, showing permissions
+- Left-align text, right-align numbers
+- Keep simple - avoid nested formatting when possible
+
+### Code Blocks
+
+- **Always specify language**: `` ```sh ``, `` ```yaml ``, `` ```go ``
+- Include comments for complex examples
+- Keep minimal - show only relevant configuration
+
+## Document Length
+
+- **Comprehensive but scannable**: Cover all aspects but use clear headings
+- **Break up long sections**: Use H3 subheadings for logical chunks
+- **Visual hierarchy**: Images and code blocks break up text
+
+## Auto-Generated Content
+
+Some content is auto-generated with comments:
+
+```markdown
+<!-- Code generated by 'make docs/...' DO NOT EDIT -->
+```
+
+Don't manually edit auto-generated sections.
+
+## URL Redirects
+
+When renaming or moving documentation pages, redirects must be added to prevent broken links.
+
+**Important**: Redirects are NOT configured in this repository. The coder.com website runs on Vercel with Next.js and reads redirects from a separate repository:
+
+- **Redirect configuration**: https://github.com/coder/coder.com/blob/master/redirects.json
+- **Do NOT create** a `docs/_redirects` file - this format (used by Netlify/Cloudflare Pages) is not processed by coder.com
+
+When you rename or move a doc page, create a PR in coder/coder.com to add the redirect.
+
+## Key Principles
+
+1. **Research first** - Verify against actual code implementation
+2. **Be precise** - Use exact numbers, permission names, API paths
+3. **Visual structure** - Organize around screenshots when available
+4. **Link everything** - Related docs, API endpoints, CLI references
+5. **Manifest inclusion** - Add to manifest.json for navigation
+6. **Add redirects** - When moving/renaming pages, add redirects in coder/coder.com repo

+# Pull Request Description Style Guide
+
+This guide documents the PR description style used in the Coder repository, based on analysis of recent merged PRs.
+
+## PR Title Format
+
+Follow [Conventional Commits 1.0.0](https://www.conventionalcommits.org/en/v1.0.0/) format:
+
+```text
+type(scope): brief description
+```
+
+**Common types:**
+
+- `feat`: New features
+- `fix`: Bug fixes
+- `refactor`: Code refactoring without behavior change
+- `perf`: Performance improvements
+- `docs`: Documentation changes
+- `chore`: Dependency updates, tooling changes
+
+**Examples:**
+
+- `feat: add tracing to aibridge`
+- `fix: move contexts to appropriate locations`
+- `perf(coderd/database): add index on workspace_app_statuses.app_id`
+- `docs: fix swagger tags for license endpoints`
+- `refactor(site): remove redundant client-side sorting of app statuses`
+
+## PR Description Structure
+
+### Default Pattern: Keep It Concise
+
+Most PRs use a simple 1-2 paragraph format:
+
+```markdown
+[Brief statement of what changed]
+
+[One sentence explaining technical details or context if needed]
+```
+
+**Example (bugfix):**
+
+```markdown
+Previously, when a devcontainer config file was modified, the dirty
+status was updated internally but not broadcast to websocket listeners.
+
+Add `broadcastUpdatesLocked()` call in `markDevcontainerDirty` to notify
+websocket listeners immediately when a config file changes.
+```
+
+**Example (dependency update):**
+
+```markdown
+Changes from https://github.com/upstream/repo/pull/XXX/
+```
+
+**Example (docs correction):**
+
+```markdown
+Removes incorrect references to database replicas from the scaling documentation.
+Coder only supports a single database connection URL.
+```
+
+### For Complex Changes: Use "Summary", "Problem", "Fix"
+
+Only use structured sections when the change requires significant explanation:
+
+```markdown
+## Summary
+Brief overview of the change
+
+## Problem
+Detailed explanation of the issue being addressed
+
+## Fix
+How the solution works
+```
+
+**Example (API documentation fix):**
+
+```markdown
+## Summary
+Change `@Tags` from `Organizations` to `Enterprise` for POST /licenses...
+
+## Problem
+The license API endpoints were inconsistently tagged...
+
+## Fix
+Simply updated the `@Tags` annotation from `Organizations` to `Enterprise`...
+```
+
+### For Large Refactors: Lead with Context
+
+When rewriting significant documentation or code, start with the problems being fixed:
+
+```markdown
+This PR rewrites [component] for [reason].
+
+The previous [component] had [specific issues]: [details].
+
+[What changed]: [specific improvements made].
+
+[Additional changes]: [context].
+
+Refs #[issue-number]
+```
+
+**Example (major documentation rewrite):**
+
+- Started with "This PR rewrites the dev containers documentation for GA readiness"
+- Listed specific inaccuracies being fixed
+- Explained organizational changes
+- Referenced related issue
+
+## What to Include
+
+### Always Include
+
+1. **Link Related Work**
+   - `Closes https://github.com/coder/internal/issues/XXX`
+   - `Depends on #XXX`
+   - `Fixes: https://github.com/coder/aibridge/issues/XX`
+   - `Refs #XXX` (for general reference)
+
+2. **Performance Context** (when relevant)
+
+   ```markdown
+   Each query took ~30ms on average with 80 requests/second to the cluster,
+   resulting in ~5.2 query-seconds every second.
+   ```
+
+3. **Migration Warnings** (when relevant)
+
+   ```markdown
+   **NOTE**: This migration creates an index on `workspace_app_statuses`.
+   For deployments with heavy task usage, this may take a moment to complete.
+   ```
+
+4. **Visual Evidence** (for UI changes)
+
+   ```markdown
+   <img width="1281" height="425" alt="image" src="..." />
+   ```
+
+### Never Include
+
+- ❌ **Test plans** - Testing is handled through code review and CI
+- ❌ **"Benefits" sections** - Benefits should be clear from the description
+- ❌ **Implementation details** - Keep it high-level
+- ❌ **Marketing language** - Stay technical and factual
+- ❌ **Bullet lists of features** (unless it's a large refactor that needs enumeration)
+
+## Special Patterns
+
+### Simple Chore PRs
+
+For straightforward updates (dependency bumps, minor fixes):
+
+```markdown
+Changes from [link to upstream PR/issue]
+```
+
+Or:
+
+```markdown
+Reference:
+[link explaining why this change is needed]
+```
+
+### Bug Fixes
+
+Start with the problem, then explain the fix:
+
+```markdown
+[What was broken and why it matters]
+
+[What you changed to fix it]
+```
+
+### Dependency Updates
+
+Dependabot PRs are auto-generated - don't try to match their verbose style for manual updates. Instead use:
+
+```markdown
+Changes from https://github.com/upstream/repo/pull/XXX/
+```
+
+## Attribution Footer
+
+For AI-generated PRs, end with:
+
+```markdown
+🤖 Generated with [Claude Code](https://claude.com/claude-code)
+
+Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
+```
+
+## Creating PRs as Draft
+
+**IMPORTANT**: Unless explicitly told otherwise, always create PRs as drafts using the `--draft` flag:
+
+```bash
+gh pr create --draft --title "..." --body "..."
+```
+
+After creating the PR, encourage the user to review it before marking as ready:
+
+```
+I've created draft PR #XXXX. Please review the changes and mark it as ready for review when you're satisfied.
+```
+
+This allows the user to:
+- Review the code changes before requesting reviews from maintainers
+- Make additional adjustments if needed
+- Ensure CI passes before notifying reviewers
+- Control when the PR enters the review queue
+
+Only create non-draft PRs when the user explicitly requests it or when following up on an existing draft.
+
+## Key Principles
+
+1. **Always create draft PRs** - Unless explicitly told otherwise
+2. **Be concise** - Default to 1-2 paragraphs unless complexity demands more
+3. **Be technical** - Explain what and why, not detailed how
+4. **Link everything** - Issues, PRs, upstream changes, Notion docs
+5. **Show impact** - Metrics for performance, screenshots for UI, warnings for migrations
+6. **No test plans** - Code review and CI handle testing
+7. **No benefits sections** - Benefits should be obvious from the technical description
+
+## Examples by Category

-# Cursor Rules
-
-This project is called "Coder" - an application for managing remote development environments.
-
-Coder provides a platform for creating, managing, and using remote development environments (also known as Cloud Development Environments or CDEs). It leverages Terraform to define and provision these environments, which are referred to as "workspaces" within the project. The system is designed to be extensible, secure, and provide developers with a seamless remote development experience.
-
-## Core Architecture
-
-The heart of Coder is a control plane that orchestrates the creation and management of workspaces. This control plane interacts with separate Provisioner processes over gRPC to handle workspace builds. The Provisioners consume workspace definitions and use Terraform to create the actual infrastructure.
-
-The CLI package serves dual purposes - it can be used to launch the control plane itself and also provides client functionality for users to interact with an existing control plane instance. All user-facing frontend code is developed in TypeScript using React and lives in the `site/` directory.
-
-The database layer uses PostgreSQL with SQLC for generating type-safe database code. Database migrations are carefully managed to ensure both forward and backward compatibility through paired `.up.sql` and `.down.sql` files.
-
-## API Design
-
-Coder's API architecture combines REST and gRPC approaches. The REST API is defined in `coderd/coderd.go` and uses Chi for HTTP routing. This provides the primary interface for the frontend and external integrations.
-
-Internal communication with Provisioners occurs over gRPC, with service definitions maintained in `.proto` files. This separation allows for efficient binary communication with the components responsible for infrastructure management while providing a standard REST interface for human-facing applications.
-
-## Network Architecture
-
-Coder implements a secure networking layer based on Tailscale's Wireguard implementation. The `tailnet` package provides connectivity between workspace agents and clients through DERP (Designated Encrypted Relay for Packets) servers when direct connections aren't possible. This creates a secure overlay network allowing access to workspaces regardless of network topology, firewalls, or NAT configurations.
-
-### Tailnet and DERP System
-
-The networking system has three key components:
-
-1. **Tailnet**: An overlay network implemented in the `tailnet` package that provides secure, end-to-end encrypted connections between clients, the Coder server, and workspace agents.
-
-2. **DERP Servers**: These relay traffic when direct connections aren't possible. Coder provides several options:
-   - A built-in DERP server that runs on the Coder control plane
-   - Integration with Tailscale's global DERP infrastructure
-   - Support for custom DERP servers for lower latency or offline deployments
-
-3. **Direct Connections**: When possible, the system establishes peer-to-peer connections between clients and workspaces using STUN for NAT traversal. This requires both endpoints to send UDP traffic on ephemeral ports.
-
-### Workspace Proxies
-
-Workspace proxies (in the Enterprise edition) provide regional relay points for browser-based connections, reducing latency for geo-distributed teams. Key characteristics:
-
-- Deployed as independent servers that authenticate with the Coder control plane
-- Relay connections for SSH, workspace apps, port forwarding, and web terminals
-- Do not make direct database connections
-- Managed through the `coder wsproxy` commands
-- Implemented primarily in the `enterprise/wsproxy/` package
-
-## Agent System
-
-The workspace agent runs within each provisioned workspace and provides core functionality including:
-
-- SSH access to workspaces via the `agentssh` package
-- Port forwarding
-- Terminal connectivity via the `pty` package for pseudo-terminal support
-- Application serving
-- Healthcheck monitoring
-- Resource usage reporting
-
-Agents communicate with the control plane using the tailnet system and authenticate using secure tokens.
-
-## Workspace Applications
-
-Workspace applications (or "apps") provide browser-based access to services running within workspaces. The system supports:
-
-- HTTP(S) and WebSocket connections
-- Path-based or subdomain-based access URLs
-- Health checks to monitor application availability
-- Different sharing levels (owner-only, authenticated users, or public)
-- Custom icons and display settings
-
-The implementation is primarily in the `coderd/workspaceapps/` directory with components for URL generation, proxying connections, and managing application state.
-
-## Implementation Details
-
-The project structure separates frontend and backend concerns. React components and pages are organized in the `site/src/` directory, with Jest used for testing. The backend is primarily written in Go, with a strong emphasis on error handling patterns and test coverage.
-
-Database interactions are carefully managed through migrations in `coderd/database/migrations/` and queries in `coderd/database/queries/`. All new queries require proper database authorization (dbauthz) implementation to ensure that only users with appropriate permissions can access specific resources.
-
-## Authorization System
-
-The database authorization (dbauthz) system enforces fine-grained access control across all database operations. It uses role-based access control (RBAC) to validate user permissions before executing database operations. The `dbauthz` package wraps the database store and performs authorization checks before returning data. All database operations must pass through this layer to ensure security.
-
-## Testing Framework
-
-The codebase has a comprehensive testing approach with several key components:
-
-1. **Parallel Testing**: All tests must use `t.Parallel()` to run concurrently, which improves test suite performance and helps identify race conditions.
-
-2. **coderdtest Package**: This package in `coderd/coderdtest/` provides utilities for creating test instances of the Coder server, setting up test users and workspaces, and mocking external components.
-
-3. **Integration Tests**: Tests often span multiple components to verify system behavior, such as template creation, workspace provisioning, and agent connectivity.
-
-4. **Enterprise Testing**: Enterprise features have dedicated test utilities in the `coderdenttest` package.
-
-## Open Source and Enterprise Components
-
-The repository contains both open source and enterprise components:
-
-- Enterprise code lives primarily in the `enterprise/` directory
-- Enterprise features focus on governance, scalability (high availability), and advanced deployment options like workspace proxies
-- The boundary between open source and enterprise is managed through a licensing system
-- The same core codebase supports both editions, with enterprise features conditionally enabled
-
-## Development Philosophy
-
-Coder emphasizes clear error handling, with specific patterns required:
-
-- Concise error messages that avoid phrases like "failed to"
-- Wrapping errors with `%w` to maintain error chains
-- Using sentinel errors with the "err" prefix (e.g., `errNotFound`)
-
-All tests should run in parallel using `t.Parallel()` to ensure efficient testing and expose potential race conditions. The codebase is rigorously linted with golangci-lint to maintain consistent code quality.
-
-Git contributions follow a standard format with commit messages structured as `type: <message>`, where type is one of `feat`, `fix`, or `chore`.
-
-## Development Workflow
-
-Development can be initiated using `scripts/develop.sh` to start the application after making changes. Database schema updates should be performed through the migration system using `create_migration.sh <name>` to generate migration files, with each `.up.sql` migration paired with a corresponding `.down.sql` that properly reverts all changes.
-
-If the development database gets into a bad state, it can be completely reset by removing the PostgreSQL data directory with `rm -rf .coderv2/postgres`. This will destroy all data in the development database, requiring you to recreate any test users, templates, or workspaces after restarting the application.
-
-Code generation for the database layer uses `coderd/database/generate.sh`, and developers should refer to `sqlc.yaml` for the appropriate style and patterns to follow when creating new queries or tables.
-
-The focus should always be on maintaining security through proper database authorization, clean error handling, and comprehensive test coverage to ensure the platform remains robust and reliable.

+          You are an expert software engineer triaging customer-reported issues for Coder, a cloud development environment platform.
+
+          Your task is to carefully analyze issue #${ISSUE_NUMBER} and classify it into one of the following severity levels. **This requires deep reasoning and thoughtful analysis** - not just keyword matching.
+
+          Issue URL: ${ISSUE_URL}
+
+          WORKFLOW:
+            1. Use GitHub MCP tools to fetch the full issue details
+               Get the title, description, labels, and any comments that provide context
+
+            2. Read and understand the issue
+               What is the user reporting?
+               What are the symptoms?
+               What is the expected vs actual behavior?
+
+            3. Analyze using the framework below
+               Think deeply about each of the 5 analysis points
+               Don't just match keywords - reason about the actual impact
+
+            4. Classify the severity OR decline if insufficient information
+
+            5. Comment on the issue with your analysis
+
+          ## Severity Level Definitions
+
+          - **s0**: Entire product and/or major feature (Tasks, Bridge, Boundaries, etc.) is broken in a way that makes it unusable for majority to all customers
+
+          - **s1**: Core feature is broken without a workaround for limited number of customers
+
+          - **s2**: Broken use cases or features with a workaround
+
+          - **s3**: Issues that impair usability, cause incorrect behavior in non-critical areas, or degrade the experience, but do not block core workflows
+
+          - **s4**: Bugs that confuse or annoy or are purely cosmetic, e.g. we don't plan on addressing them
+
+          ## Analysis Framework
+
+          Customers often overstate the severity of issues. You need to read between the lines and assess the **actual impact** by reasoning through:
+
+          1. **What is actually broken?**
+             - Distinguish between what the customer *says* is broken vs. what is *actually* broken
+             - Is this a complete failure or a partial degradation?
+             - Does the error message or symptom indicate a critical vs. minor issue?
+
+          2. **How many users are affected?**
+             - Is this affecting all customers, many customers, or a specific edge case?
+             - Does the issue description suggest widespread impact or isolated incident?
+             - Are there environmental factors that limit the scope?
+
+          3. **Are there workarounds?**
+             - Can users accomplish their goal through an alternative path?
+             - Is there a manual process or configuration change that resolves it?
+             - Even if not mentioned, do you suspect a workaround exists?
+
+          4. **Does it block critical workflows?**
+             - Can users still perform their core job functions?
+             - Is this interrupting active development work or just an inconvenience?
+             - What is the business impact if this remains unresolved?
+
+          5. **What is the realistic urgency?**
+             - Does this need immediate attention or can it wait?
+             - Is this a regression or long-standing issue?
+             - What's the actual business risk?
+
+          ## Insufficient Information Fail-Safe
+
+          **It is completely acceptable to not classify an issue if you lack sufficient information.**
+
+          If the issue description is too vague, missing critical details, or doesn't provide enough context to make a confident assessment, DO NOT force a classification.
+
+          Common scenarios where you should decline to classify:
+          - Issue has no description or minimal details
+          - Unclear what feature/component is affected
+          - No reproduction steps or error messages provided
+          - Ambiguous whether it's a bug, feature request, or question
+          - Missing information about user impact or frequency
+
+          ## Comment Format
+
+          Use ONE of these two formats when commenting on the issue:
+
+          ### Format 1: Confident Classification
+
+          ## 🤖 Automated Severity Classification
+
+          **Recommended Severity:** \`S0\` | \`S1\` | \`S2\` | \`S3\` | \`S4\`
+
+          **Analysis:**
+          [2-3 sentences explaining your reasoning - focus on the actual impact, not just symptoms. Explain why you chose this severity level over others.]

+          </security_instruction>
+
+          <instructions>
+          YOUR JOB:
+            - Find bugs and security issues that would break production
+            - Be thorough but accurate - read full files to verify issues exist
+            - Think critically about what could actually go wrong
+            - Make every observation actionable with a suggestion
+            - Refer to AGENTS.md for Coder-specific patterns and conventions
+
+          SEVERITY LEVELS:
+            🔴 CRITICAL: Security vulnerabilities, auth bypass, data corruption, crashes
+            🟡 IMPORTANT: Logic bugs, race conditions, resource leaks, unhandled errors
+            🔵 NITPICK: Minor improvements, style issues, portability concerns
+
+          COMMENT STYLE:
+            - CRITICAL/IMPORTANT: Standard inline suggestions
+            - NITPICKS: Prefix with "[NITPICK]" in the issue description
+            - All observations must have actionable suggestions (not just summary mentions)
+
+          DON'T COMMENT ON:
+            ❌ Style that matches existing Coder patterns (check AGENTS.md first)
+            ❌ Code that already exists (read the file first!)
+            ❌ Unnecessary changes unrelated to the PR
+
+          IMPORTANT - UNDERSTAND set -u:
+            set -u only catches UNDEFINED/UNSET variables. It does NOT catch empty strings.
+
+            Examples:
+            - unset VAR; echo \${VAR}         → ERROR with set -u (undefined)
+            - VAR=""; echo \${VAR}            → OK with set -u (defined, just empty)
+            - VAR="\${INPUT:-}"; echo \${VAR} → OK with set -u (always defined, may be empty)
+
+            GitHub Actions context variables (github.*, inputs.*) are ALWAYS defined.
+            They may be empty strings, but they are never undefined.
+
+            Don't comment on set -u unless you see actual undefined variable access.
+          </instructions>
+
+          <github_api_documentation>
+          HOW GITHUB SUGGESTIONS WORK:
+          Your suggestion block REPLACES the commented line(s). Don't include surrounding context!
+
+          Example (fictional):
+          49: # Comment line
+          50: OLDCODE=\$(bad command)
+          51: echo "done"
+
+          ❌ WRONG - includes unchanged lines 49 and 51:
+          {"line": 50, "body": "Issue\\n\\n\`\`\`suggestion\\n# Comment line\\nNEWCODE\\necho \\"done\\"\\n\`\`\`"}
+          Result: Lines 49 and 51 duplicated!
+
+          ✅ CORRECT - only the replacement for line 50:
+          {"line": 50, "body": "Issue\\n\\n\`\`\`suggestion\\nNEWCODE=\$(good command)\\n\`\`\`"}
+          Result: Only line 50 replaced. Perfect!
+
+          COMMENT FORMAT:
+          Single line: {"path": "file.go", "line": 50, "side": "RIGHT", "body": "Issue\\n\\n\`\`\`suggestion\\n[code]\\n\`\`\`"}
+          Multi-line: {"path": "file.go", "start_line": 50, "line": 52, "side": "RIGHT", "body": "Issue\\n\\n\`\`\`suggestion\\n[code]\\n\`\`\`"}
+
+          SUMMARY FORMAT (1-10 lines, conversational):
+          With issues: "## 🔍 Code Review\\n\\nReviewed [5-8 words].\\n\\n**Found X issues** (Y critical, Z nitpicks).\\n\\n---\\n*AI review via [Coder Tasks](https://coder.com/docs/ai-coder/tasks)*"

+          </github_api_documentation>
+
+          <critical_rules>
+          1. Read ENTIRE files before commenting - use read_file or grep to verify
+          2. Check the EXACT line you're commenting on - does the issue actually exist there?
+          3. Suggestion block = ONLY replacement lines (never include unchanged surrounding lines)
+          4. Single line: {"line": 50} | Multi-line: {"start_line": 50, "line": 52}
+          5. Explain IMPACT ("causes crash/leak/bypass" not "could be better")
+          6. Make ALL observations actionable with suggestions (not just summary mentions)
+          7. set -u = undefined vars only. Don't claim it catches empty strings. It doesn't.
+          8. No issues = {"event": "COMMENT", "comments": [], "body": "[summary with Coder Tasks link]"}

+

+
+            5. Decide
+               NEEDS DOCS if: New feature, API change, CLI change, behavior change, user-visible
+               NO DOCS if: Internal refactor, test-only, already documented, non-user-facing, dependency updates
+               FIRST check: Did this PR already update docs? If yes and complete, say "No Changes Needed"
+
+            6. Comment on the PR using this format
+
+          COMMENT FORMAT:
+          ## 📚 Documentation Check
+
+          ### ✅ Updates Needed
+          - **[docs/path/file.md](github_link)** - Brief what needs changing
+
+          ### 📝 New Docs Needed
+          - **docs/suggested/location.md** - What should be documented
+
+          ### ✨ No Changes Needed
+          [Reason: Documents already updated in PR | Internal changes only | Test-only | No user-facing impact]

+# Coder Development Guidelines
+
+You are an experienced, pragmatic software engineer. You don't over-engineer a solution when a simple one is possible.
+Rule #1: If you want exception to ANY rule, YOU MUST STOP and get explicit permission first. BREAKING THE LETTER OR SPIRIT OF THE RULES IS FAILURE.
+
+## Foundational rules
+
+- Doing it right is better than doing it fast. You are not in a rush. NEVER skip steps or take shortcuts.
+- Tedious, systematic work is often the correct solution. Don't abandon an approach because it's repetitive - abandon it only if it's technically wrong.
+- Honesty is a core value.
+
+## Our relationship
+
+- Act as a critical peer reviewer. Your job is to disagree with me when I'm wrong, not to please me. Prioritize accuracy and reasoning over agreement.
+- YOU MUST speak up immediately when you don't know something or we're in over our heads
+- YOU MUST call out bad ideas, unreasonable expectations, and mistakes - I depend on this
+- NEVER be agreeable just to be nice - I NEED your HONEST technical judgment
+- NEVER write the phrase "You're absolutely right!"  You are not a sycophant. We're working together because I value your opinion. Do not agree with me unless you can justify it with evidence or reasoning.
+- YOU MUST ALWAYS STOP and ask for clarification rather than making assumptions.
+- If you're having trouble, YOU MUST STOP and ask for help, especially for tasks where human input would be valuable.
+- When you disagree with my approach, YOU MUST push back. Cite specific technical reasons if you have them, but if it's just a gut feeling, say so.
+- If you're uncomfortable pushing back out loud, just say "Houston, we have a problem". I'll know what you mean
+- We discuss architectutral decisions (framework changes, major refactoring, system design) together before implementation. Routine fixes and clear implementations don't need discussion.
+
+## Proactiveness
+
+When asked to do something, just do it - including obvious follow-up actions needed to complete the task properly.
+Only pause to ask for confirmation when:
+
+- Multiple valid approaches exist and the choice matters
+- The action would delete or significantly restructure existing code
+- You genuinely don't understand what's being asked
+- Your partner asked a question (answer the question, don't jump to implementation)
+

+
+## Essential Commands
+
+| Task              | Command                  | Notes                            |
+|-------------------|--------------------------|----------------------------------|
+| **Development**   | `./scripts/develop.sh`   | ⚠️ Don't use manual build        |
+| **Build**         | `make build`             | Fat binaries (includes server)   |
+| **Build Slim**    | `make build-slim`        | Slim binaries                    |
+| **Test**          | `make test`              | Full test suite                  |
+| **Test Single**   | `make test RUN=TestName` | Faster than full suite           |
+| **Test Postgres** | `make test-postgres`     | Run tests with Postgres database |
+| **Test Race**     | `make test-race`         | Run tests with Go race detector  |
+| **Lint**          | `make lint`              | Always run after changes         |
+| **Generate**      | `make gen`               | After database changes           |
+| **Format**        | `make fmt`               | Auto-format code                 |
+| **Clean**         | `make clean`             | Clean build artifacts            |
+
+### Documentation Commands
+
+- `pnpm run format-docs` - Format markdown tables in docs
+- `pnpm run lint-docs` - Lint and fix markdown files
+- `pnpm run storybook` - Run Storybook (from site directory)
+
+## Critical Patterns
+
+### Database Changes (ALWAYS FOLLOW)
+
+1. Modify `coderd/database/queries/*.sql` files
+2. Run `make gen`
+3. If audit errors: update `enterprise/audit/table.go`
+4. Run `make gen` again
+
+### LSP Navigation (USE FIRST)
+
+#### Go LSP (for backend code)
+
+- **Find definitions**: `mcp__go-language-server__definition symbolName`
+- **Find references**: `mcp__go-language-server__references symbolName`
+- **Get type info**: `mcp__go-language-server__hover filePath line column`
+- **Rename symbol**: `mcp__go-language-server__rename_symbol filePath line column newName`
+
+#### TypeScript LSP (for frontend code in site/)
+
+- **Find definitions**: `mcp__typescript-language-server__definition symbolName`
+- **Find references**: `mcp__typescript-language-server__references symbolName`
+- **Get type info**: `mcp__typescript-language-server__hover filePath line column`
+- **Rename symbol**: `mcp__typescript-language-server__rename_symbol filePath line column newName`
+
+### OAuth2 Error Handling
+
+```go
+// OAuth2-compliant error responses
+writeOAuth2Error(ctx, rw, http.StatusBadRequest, "invalid_grant", "description")
+```
+
+### Authorization Context
+
+```go
+// Public endpoints needing system access
+app, err := api.Database.GetOAuth2ProviderAppByClientID(dbauthz.AsSystemRestricted(ctx), clientID)
+
+// Authenticated endpoints with user context
+app, err := api.Database.GetOAuth2ProviderAppByClientID(ctx, clientID)
+```
+
+## Quick Reference
+
+### Full workflows available in imported WORKFLOWS.md
+
+### Git Workflow
+
+When working on existing PRs, check out the branch first:
+
+```sh
+git fetch origin
+git checkout branch-name
+git pull origin branch-name
+```
+
+Don't use `git push --force` unless explicitly requested.
+
+### New Feature Checklist
+
+- [ ] Run `git pull` to ensure latest code
+- [ ] Check if feature touches database - you'll need migrations
+- [ ] Check if feature touches audit logs - update `enterprise/audit/table.go`
+
+## Architecture
+
+- **coderd**: Main API service
+- **provisionerd**: Infrastructure provisioning
+- **Agents**: Workspace services (SSH, port forwarding)
+- **Database**: PostgreSQL with `dbauthz` authorization
+
+## Testing
+
+### Race Condition Prevention
+
+- Use unique identifiers: `fmt.Sprintf("test-client-%s-%d", t.Name(), time.Now().UnixNano())`
+- Never use hardcoded names in concurrent tests
+
+### OAuth2 Testing
+
+- Full suite: `./scripts/oauth2/test-mcp-oauth2.sh`
+- Manual testing: `./scripts/oauth2/test-manual-flow.sh`
+
+### Timing Issues
+
+NEVER use `time.Sleep` to mitigate timing issues. If an issue
+seems like it should use `time.Sleep`, read through https://github.com/coder/quartz and specifically the [README](https://github.com/coder/quartz/blob/main/README.md) to better understand how to handle timing issues.
+
+## Code Style
+
+### Detailed guidelines in imported WORKFLOWS.md
+
+- Follow [Uber Go Style Guide](https://github.com/uber-go/guide/blob/master/style.md)
+- Commit format: `type(scope): message`
+
+### Writing Comments
+
+Code comments should be clear, well-formatted, and add meaningful context.
+
+**Proper sentence structure**: Comments are sentences and should end with
+periods or other appropriate punctuation. This improves readability and
+maintains professional code standards.
+
+**Explain why, not what**: Good comments explain the reasoning behind code
+rather than describing what the code does. The code itself should be
+self-documenting through clear naming and structure. Focus your comments on
+non-obvious decisions, edge cases, or business logic that isn't immediately
+apparent from reading the implementation.
+
+**Line length and wrapping**: Keep comment lines to 80 characters wide
+(including the comment prefix like `//` or `#`). When a comment spans multiple
+lines, wrap it naturally at word boundaries rather than writing one sentence
+per line. This creates more readable, paragraph-like blocks of documentation.
+
+```go
+// Good: Explains the rationale with proper sentence structure.
+// We need a custom timeout here because workspace builds can take several
+// minutes on slow networks, and the default 30s timeout causes false
+// failures during initial template imports.
+ctx, cancel := context.WithTimeout(ctx, 5*time.Minute)
+
+// Bad: Describes what the code does without punctuation or wrapping
+// Set a custom timeout
+// Workspace builds can take a long time
+// Default timeout is too short
+ctx, cancel := context.WithTimeout(ctx, 5*time.Minute)
+```
+
+### Avoid Unnecessary Changes
+
+When fixing a bug or adding a feature, don't modify code unrelated to your
+task. Unnecessary changes make PRs harder to review and can introduce
+regressions.
+
+**Don't reword existing comments or code** unless the change is directly
+motivated by your task. Rewording comments to be shorter or "cleaner" wastes
+reviewer time and clutters the diff.
+
+**Don't delete existing comments** that explain non-obvious behavior. These
+comments preserve important context about why code works a certain way.
+
+**When adding tests for new behavior**, add new test cases instead of modifying
+existing ones. This preserves coverage for the original behavior and makes it
+clear what the new test covers.
