+# 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
+
+### Performance Improvements
+
+Includes query timing metrics and explains the index solution
+
+### Bug Fixes
+
+Describes broken behavior then the fix in two sentences
+
+### Documentation
+
+- **Major rewrite**: Long form explaining inaccuracies and improvements
+- **Simple correction**: One sentence for simple correction
+
+### Features
+
+Simple statement of what was added and dependencies
+
+### Refactoring
+
+Explains why client-side sorting is now redundant
+
+### Configuration
+
+Adds guidelines with issue reference

+## Git Workflow
+
+### Working on PR branches
+
+When working on an existing PR branch:
+
+```sh
+git fetch origin
+git checkout branch-name
+git pull origin branch-name
+```
+
+Then make your changes and push normally. Don't use `git push --force` unless the user specifically asks for it.

+          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.]
+
+          ---
+          *This classification was performed by AI analysis. Please review and adjust if needed.*
+
+          ### Format 2: Insufficient Information
+
+          ## 🤖 Automated Severity Classification
+
+          **Status:** Unable to classify - insufficient information
+
+          **Reasoning:**
+          [2-3 sentences explaining what critical information is missing and why it's needed to determine severity.]
+
+          **Suggested next steps:**
+          - [Specific information point 1]
+          - [Specific information point 2]
+          - [Specific information point 3]
+
+          ---
+          *This classification was performed by AI analysis. Please provide the requested information for proper severity assessment.*

+            - 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!

+# 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.

-## Quick Reference
-
-### Full workflows available in imported WORKFLOWS.md
-
-### 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)
-```

-## Common Pitfalls
-
-1. **Audit table errors** → Update `enterprise/audit/table.go`
-2. **OAuth2 errors** → Return RFC-compliant format
-3. **Race conditions** → Use unique test identifiers
-4. **Missing newlines** → Ensure files end with newline
