--- name: compound-docs description: Capture solved problems as categorized documentation with YAML frontmatter for fast lookup allowed-tools: - Read # Parse conversation context - Write # Create resolution docs - Bash # Create directories - Grep # Search existing docs preconditions: - Problem has been solved (not in-progress) - Solution has been verified working --- # compound-docs Skill **Purpose:** Automatically document solved problems to build searchable institutional knowledge with category-based organization (enum-validated problem types). ## Overview This skill captures problem solutions immediately after confirmation, creating structured documentation that serves as a searchable knowledge base for future sessions. **Organization:** Single-file architecture - each problem documented as one markdown file in its symptom category directory (e.g., `.claude\/solutions\/performance-issues\/n-plus-one-briefs.md`). Files use YAML frontmatter for metadata and searchability. --- ## 7-Step Process ### Step 1: Detect Confirmation **Auto-invoke after phrases:** - "that worked" - "it's fixed" - "working now" - "problem solved" - "that did it" **OR manual:** `\/doc-fix` command **Non-trivial problems only:** - Multiple investigation attempts needed - Tricky debugging that took time - Non-obvious solution - Future sessions would benefit **Skip documentation for:** - Simple typos - Obvious syntax errors - Trivial fixes immediately corrected <\/step> ### Step 2: Gather Context Extract from conversation history: **Required information:** - **Module name**: Which CORA module had the problem - **Symptom**: Observable error\/behavior (exact error messages) - **Investigation attempts**: What didn't work and why - **Root cause**: Technical explanation of actual problem - **Solution**: What fixed it (code\/config changes) - **Prevention**: How to avoid in future **Environment details:** - Rails version - Stage (0-6 or post-implementation) - OS version - File\/line references **BLOCKING REQUIREMENT:** If critical context is missing (module name, exact error, stage, or resolution steps), ask user and WAIT for response before proceeding to Step 3: ``` I need a few details to document this properly: 1. Which module had this issue? [ModuleName] 2. What was the exact error message or symptom? 3. What stage were you in? (0-6 or post-implementation) [Continue after user provides details] ``` <\/step> ### Step 3: Check Existing Docs Search .claude\/solutions\/ for similar issues: ```bash # Search by error message keywords grep -r "exact error phrase" .claude\/solutions\/ # Search by symptom category ls .claude\/solutions\/[category]\/ ``` **IF similar issue found:** THEN present decision options: ``` Found similar issue: .claude\/solutions\/[path] What's next? 1. Create new doc with cross-reference (recommended) 2. Update existing doc (only if same root cause) 3. Other Choose (1-3): _ ``` WAIT for user response, then execute chosen action. **ELSE** (no similar issue found): Proceed directly to Step 4 (no user interaction needed). <\/step> ### Step 4: Generate Filename Format: `[sanitized-symptom]-[module]-[YYYYMMDD].md` **Sanitization rules:** - Lowercase - Replace spaces with hyphens - Remove special characters except hyphens - Truncate to reasonable length (< 80 chars) **Examples:** - `missing-include-BriefSystem-20251110.md` - `parameter-not-saving-state-EmailProcessing-20251110.md` - `webview-crash-on-resize-Assistant-20251110.md` <\/step> ### Step 5: Validate YAML Schema **CRITICAL:** All docs require validated YAML frontmatter with enum validation. **Validate against schema:** Load `schema.yaml` and classify the problem against the enum values defined in [yaml-schema.md](.\/references\/yaml-schema.md). Ensure all required fields are present and match allowed values exactly. **BLOCK if validation fails:** ``` ❌ YAML validation failed Errors: - problem_type: must be one of schema enums, got "compilation_error" - severity: must be one of [critical, moderate, minor], got "high" - symptoms: must be array with 1-5 items, got string Please provide corrected values. ``` **GATE ENFORCEMENT:** Do NOT proceed to Step 6 (Create Documentation) until YAML frontmatter passes all validation rules defined in `schema.yaml`. <\/validation_gate> <\/step> ### Step 6: Create Documentation **Determine category from problem_type:** Use the category mapping defined in [yaml-schema.md](.\/references\/yaml-schema.md) (lines 49-61). **Create documentation file:** ```bash PROBLEM_TYPE="[from validated YAML]" CATEGORY="[mapped from problem_type]" FILENAME="[generated-filename].md" DOC_PATH=".claude\/solutions\/${CATEGORY}\/${FILENAME}" # Create directory if needed mkdir -p ".claude\/solutions\/${CATEGORY}" # Write documentation using template from assets\/resolution-template.md # (Content populated with Step 2 context and validated YAML frontmatter) ``` **Result:** - Single file in category directory - Enum validation ensures consistent categorization **Create documentation:** Populate the structure from `assets\/resolution-template.md` with context gathered in Step 2 and validated YAML frontmatter from Step 5. <\/step> ### Step 7: Cross-Reference & Critical Pattern Detection If similar issues found in Step 3: **Update existing doc:** ```bash # Add Related Issues link to similar doc echo "- See also: [$FILENAME]($REAL_FILE)" >> [similar-doc.md] ``` **Update new doc:** Already includes cross-reference from Step 6. **Update patterns if applicable:** If this represents a common pattern (3+ similar issues): ```bash # Add to .claude\/solutions\/patterns\/common-solutions.md cat >> .claude\/solutions\/patterns\/common-solutions.md << 'EOF' ## [Pattern Name] **Common symptom:** [Description] **Root cause:** [Technical explanation] **Solution pattern:** [General approach] **Examples:** - [Link to doc 1] - [Link to doc 2] - [Link to doc 3] EOF ``` **Critical Pattern Detection (Optional Proactive Suggestion):** If this issue has automatic indicators suggesting it might be critical: - Severity: `critical` in YAML - Affects multiple modules OR foundational stage (Stage 2 or 3) - Non-obvious solution Then in the decision menu (Step 8), add a note: ``` 💡 This might be worth adding to Required Reading (Option 2) ``` But **NEVER auto-promote**. User decides via decision menu (Option 2). **Template for critical pattern addition:** When user selects Option 2 (Add to Required Reading), use the template from `assets\/critical-pattern-template.md` to structure the pattern entry. Number it sequentially based on existing patterns in `.claude\/solutions\/patterns\/cora-critical-patterns.md`. <\/step> <\/critical_sequence> --- ## Decision Menu After Capture After successful documentation, present options and WAIT for user response: ``` ✓ Solution documented File created: - .claude\/solutions\/[category]\/[filename].md What's next? 1. Continue workflow (recommended) 2. Add to Required Reading - Promote to critical patterns (cora-critical-patterns.md) 3. Link related issues - Connect to similar problems 4. Add to existing skill - Add to a learning skill (e.g., hotwire-native) 5. Create new skill - Extract into new learning skill 6. View documentation - See what was captured 7. Other ``` **Handle responses:** **Option 1: Continue workflow** - Return to calling skill\/workflow - Documentation is complete **Option 2: Add to Required Reading** ⭐ PRIMARY PATH FOR CRITICAL PATTERNS User selects this when: - System made this mistake multiple times across different modules - Solution is non-obvious but must be followed every time - Foundational requirement (Rails, Rails API, threading, etc.) Action: 1. Extract pattern from the documentation 2. Format as ❌ WRONG vs ✅ CORRECT with code examples 3. Add to `.claude\/solutions\/patterns\/cora-critical-patterns.md` 4. Add cross-reference back to this doc 5. Confirm: "✓ Added to Required Reading. All subagents will see this pattern before code generation." **Option 3: Link related issues** - Prompt: "Which doc to link? (provide filename or describe)" - Search .claude\/solutions\/ for the doc - Add cross-reference to both docs - Confirm: "✓ Cross-reference added" **Option 4: Add to existing skill** User selects this when the documented solution relates to an existing learning skill: Action: 1. Prompt: "Which skill? (hotwire-native, etc.)" 2. Determine which reference file to update (resources.md, patterns.md, or examples.md) 3. Add link and brief description to appropriate section 4. Confirm: "✓ Added to [skill-name] skill in [file]" Example: For Hotwire Native Tailwind variants solution: - Add to `hotwire-native\/references\/resources.md` under "CORA-Specific Resources" - Add to `hotwire-native\/references\/examples.md` with link to solution doc **Option 5: Create new skill** User selects this when the solution represents the start of a new learning domain: Action: 1. Prompt: "What should the new skill be called? (e.g., stripe-billing, email-processing)" 2. Run `python3 .claude\/skills\/skill-creator\/scripts\/init_skill.py [skill-name]` 3. Create initial reference files with this solution as first example 4. Confirm: "✓ Created new [skill-name] skill with this solution as first example" **Option 6: View documentation** - Display the created documentation - Present decision menu again **Option 7: Other** - Ask what they'd like to do <\/decision_gate> --- ## Integration Points **Invoked by:** - \/compound command (primary interface) - Manual invocation in conversation after solution confirmed - Can be triggered by detecting confirmation phrases like "that worked", "it's fixed", etc. **Invokes:** - None (terminal skill - does not delegate to other skills) **Handoff expectations:** All context needed for documentation should be present in conversation history before invocation. <\/integration_protocol> --- ## Success Criteria Documentation is successful when ALL of the following are true: - ✅ YAML frontmatter validated (all required fields, correct formats) - ✅ File created in .claude\/solutions\/[category]\/[filename].md - ✅ Enum values match schema.yaml exactly - ✅ Code examples included in solution section - ✅ Cross-references added if related issues found - ✅ User presented with decision menu and action confirmed <\/success_criteria> --- ## Error Handling **Missing context:** - Ask user for missing details - Don't proceed until critical info provided **YAML validation failure:** - Show specific errors - Present retry with corrected values - BLOCK until valid **Similar issue ambiguity:** - Present multiple matches - Let user choose: new doc, update existing, or link as duplicate **Module not in CORA-MODULES.md:** - Warn but don't block - Proceed with documentation - Suggest: "Add [Module] to CORA-MODULES.md if not there" --- ## Execution Guidelines **MUST do:** - Validate YAML frontmatter (BLOCK if invalid per Step 5 validation gate) - Extract exact error messages from conversation - Include code examples in solution section - Create directories before writing files (`mkdir -p`) - Ask user and WAIT if critical context missing **MUST NOT do:** - Skip YAML validation (validation gate is blocking) - Use vague descriptions (not searchable) - Omit code examples or cross-references --- ## Quality Guidelines **Good documentation has:** - ✅ Exact error messages (copy-paste from output) - ✅ Specific file:line references - ✅ Observable symptoms (what you saw, not interpretations) - ✅ Failed attempts documented (helps avoid wrong paths) - ✅ Technical explanation (not just "what" but "why") - ✅ Code examples (before\/after if applicable) - ✅ Prevention guidance (how to catch early) - ✅ Cross-references (related issues) **Avoid:** - ❌ Vague descriptions ("something was wrong") - ❌ Missing technical details ("fixed the code") - ❌ No context (which version? which file?) - ❌ Just code dumps (explain why it works) - ❌ No prevention guidance - ❌ No cross-references --- ## Example Scenario **User:** "That worked! The N+1 query is fixed." **Skill activates:** 1. **Detect confirmation:** "That worked!" triggers auto-invoke 2. **Gather context:** - Module: Brief System - Symptom: Brief generation taking >5 seconds, N+1 query when loading email threads - Failed attempts: Added pagination (didn't help), checked background job performance - Solution: Added eager loading with `includes(:emails)` on Brief model - Root cause: Missing eager loading causing separate database query per email thread 3. **Check existing:** No similar issue found 4. **Generate filename:** `n-plus-one-brief-generation-BriefSystem-20251110.md` 5. **Validate YAML:** ```yaml module: Brief System date: 2025-11-10 problem_type: performance_issue component: rails_model symptoms: - "N+1 query when loading email threads" - "Brief generation taking >5 seconds" root_cause: missing_include severity: high tags: [n-plus-one, eager-loading, performance] ``` ✅ Valid 6. **Create documentation:** - `.claude\/solutions\/performance-issues\/n-plus-one-brief-generation-BriefSystem-20251110.md` 7. **Cross-reference:** None needed (no similar issues) **Output:** ``` ✓ Solution documented File created: - .claude\/solutions\/performance-issues\/n-plus-one-brief-generation-BriefSystem-20251110.md What's next? 1. Continue workflow (recommended) 2. Add to Required Reading - Promote to critical patterns (cora-critical-patterns.md) 3. Link related issues - Connect to similar problems 4. Add to existing skill - Add to a learning skill (e.g., hotwire-native) 5. Create new skill - Extract into new learning skill 6. View documentation - See what was captured 7.
