New section explicitly lists 8 forbidden actions: 1. Do NOT implement the spec (workflow creates specs only) 2. Do NOT skip clarifying questions (Phase 2 is mandatory) 3. Do NOT make technical decisions without evidence 4. Do NOT write specs in isolation (check context first) 5. Do NOT proceed without user validation (respect STOP points) 6.

- `Grep` - Search for specific decision rationale or WHY statements - -- **Phase 3 (Code Analysis):** - - `Grep` - Search for patterns, imports, framework usage - - `Read` - Inspect specific files for WHAT and HOW -

-## Confidence Assessment - -Categorize every finding by confidence level: - -### High Confidence (🟢) - -- **Criteria:** Strong evidence from working code or explicit documentation -- **Automation Examples:** - - `Grep` confirms 3+ consistent code references across different files - - Feature exists in working code with traced execution path - - Technology explicitly listed in dependencies AND usage found in code - - Design decision documented in ADR with matching code implementation -- **Manual Verification:** - - Feature exists with traced working code path - - Explicit documentation with recent timestamps - - Active usage in production code (not commented out) - -### Medium Confidence (🟡 Needs Validation) - -- **Criteria:** Inferred from context, behind feature flags, or implied -- **Automation Examples:** - - Evidence only appears in code comments (not executable code) - - `Grep` finds 1-2 references only (limited usage) - - Pattern inferred from file structure but not explicitly implemented - - Dependency listed but no usage found in code -- **Manual Verification:** - - Feature toggle currently disabled (code exists but may not be active) - - Pattern inferred from code structure (not explicitly documented) - - Outdated documentation (>6 months old) that may not reflect current code - -### Low Confidence (🔴 Unknown) - -- **Criteria:** Cannot determine from available information -- **Automation Examples:** - - No code references found via `Grep` - - Conflicting dependency versions - - Files exist but appear unreferenced -- **Manual Verification:** - - Rationale missing from both docs and code - - Conflicting information between sources (code vs. docs) - - Experimental or dormant code paths - - Dead code that may no longer be used - -**Automatic Confidence Rules:** - -- If `Grep/Glob` confirms ≥3 consistent references → Start with Medium, verify for High -- If evidence only in comments → Maximum Medium Confidence -- If no code references found → Start with Low Confidence -- If docs are >6 months old without code confirmation → Maximum Medium Confidence - -### Always Flag Medium and Low Confidence Items for User Validation - -## Process - -This is a **conversational, iterative analysis process**.

-- Pub/sub systems (Redis, RabbitMQ, Kafka) -- Event-driven patterns -- WebSocket or real-time communication - -#### Crosscutting Concerns - -**Goal:** Analyze system-wide quality attributes that cut across all components - -These concerns are often overlooked but critical for understanding system maturity: - -1. **Logging & Observability:** - - Logging framework used (Winston, Log4j, Serilog, etc.) - - Log levels and structure (structured logging JSON, plain text) - - Distributed tracing (OpenTelemetry, Jaeger, Zipkin) - - Metrics collection (Prometheus, StatsD, custom) - - **Evidence:** `Grep` for logger imports/usage, configuration files - - **Example:** "Structured logging with Winston (src/config/logger.ts:12, used in 47 files)" -

-- 🟢 High: Active implementation found with configuration and usage -- 🟡 Medium: Partial implementation or inconsistent usage -- 🔴 Low: Not implemented or unclear strategy - -**Present findings:** Crosscutting concerns summary with quality attribute assessment. - ---- - -### Phase 5: Gap Identification & User Collaboration - -**Goal:** Identify what cannot be determined from code/docs and get answers from user - -#### Automated Gap Detection - -Compare code analysis vs. documentation to find gaps, then **prioritize them**: - -**Priority Levels:** - -- 🟥 **Critical:** Blocks new development or introduces significant risk -- 🟧 **Important:** Should be resolved soon, impacts architectural decisions -- 🟨 **Minor:** Cosmetic, informational, or low-impact - -**Gap Categories with Prioritization:** - -1. **Missing Rationale:** - - Technologies used in code but no "why" in docs - - Patterns implemented but no decision record - - Architectural choices without explanation - - **Priority Assessment:** - - 🟥 Critical: Core authentication/security decisions undocumented - - 🟧 Important: Database choice, framework selection without rationale - - 🟨 Minor: Utility library choices, formatting tools - -2. **Conflicts:** - - Code contradicts documentation - - Diagrams show different structure than code - - Comments claim one thing, code does another - - **Priority Assessment:** - - 🟥 Critical: Security/auth flows mismatch code vs docs - - 🟧 Important: API contracts differ from implementation - - 🟨 Minor: Outdated diagram with minor structural differences - -3. **Unknowns:** - - Feature toggles (which are active?) - - Experimental code (what's the status?) - - Dead code (can it be removed?) - - Performance requirements (what are the targets?) - - **Priority Assessment:** - - 🟥 Critical: Feature toggles blocking production features - - 🟧 Important: Experimental code in main execution paths - - 🟨 Minor: Old commented-out code, unused utilities - -**Prioritization Rules:** - -- If gap relates to **security, auth, or data integrity** → 🟥 Critical -- If gap relates to **core business logic or API contracts** → 🟧 Important -- If gap relates to **documentation quality or code cleanup** → 🟨 Minor -- If gap **blocks spec development** → Escalate priority by one level - -#### User Questions (Focused, NOT Batch) - -Ask 3-5 targeted questions based on gaps found: - -Example: - -```text -I found some gaps that need your input: - -1. **PostgreSQL vs. MongoDB:** - - Code uses PostgreSQL (src/db/pool.ts:8) - - But there's MongoDB client code (src/mongo/client.ts:12) that appears unused - - Question: Is MongoDB deprecated? Can that code be removed? - -2. **Feature Toggle 'new_dashboard':** - - Code exists for new dashboard (src/features/dashboard-v2/) - - Currently disabled (src/config/features.ts:15: enabled: false) - - Question: What's the status? Should this be documented as experimental? - -3. **Authentication Decision:** - - JWT tokens are used (src/auth/jwt.ts) - - No documentation explains why JWT was chosen over sessions - - Question: Why was JWT selected? (This will help document the decision) -``` - -### ⛔ STOP - Wait for User Answers - -**Capture answers as direct quotes:** - -```text -[User confirmed: 2025-01-21: "MongoDB was from an early experiment, it's safe to remove."] -[User stated: "JWT chosen because we needed stateless auth for mobile clients."] -``` - ---- - -### Phase 6: Generate Comprehensive Analysis Document - -**Goal:** Create complete, evidence-based codebase context document - -**Output Modes:** - -- **Full Analysis (Default):** Complete detailed document with all sections (~10-20 pages) -- **Executive Summary Mode (Optional):** 2-page high-level summary first, then full details - -**To enable summary mode, user can request:** "Generate an executive summary first" - -#### Document Structure - -**If Executive Summary Mode requested, start with:** - -```markdown -# Executive Summary: [Project Name] - -**Date:** YYYY-MM-DD | **Analysis Scope:** [Full/Partial] - -## Quick Facts -- Repository Type, Languages, Architecture, Key Technologies, Maturity Level - -## Strengths -- ✅ List 3-5 key strengths with evidence - -## Areas Needing Attention -- ⚠️ List 3-5 priority concerns with priority levels (🟥🟧🟨) - -## Recommended Next Steps -1-3 actionable next steps - ---- -**Full detailed analysis follows below...** -``` - -#### Full Analysis Structure - -```markdown -# Codebase Context: [Project Name] - -**Date:** YYYY-MM-DD -**Scope:** [Full codebase / Specific components] -**Purpose:** [From user's stated purpose] - ---- - -## 1.

Non-members and non-collaborators are still blocked 🤖 Generated with Claude Code Co-Authored-By: Claude --- .github/workflows/claude.yml | 63 +++++++++++++++++----- .github/workflows/opencode-gpt-5-codex.yml | 63 +++++++++++++++++----- 2 files changed, 100 insertions(+), 26 deletions(-) diff --git a/.github/workflows/claude.yml b/.github/workflows/claude.yml index a7580ee..2d8150c 100644 --- a/.github/workflows/claude.yml +++ b/.github/workflows/claude.yml @@ -11,33 +11,70 @@ on: types: [submitted] jobs: - claude: - timeout-minutes: 10 - concurrency: - group: claude-${{ github.event_name }}-${{ github.event.issue.number || github.event.pull_request.number || github.run_id }} - cancel-in-progress: true + # Check if the user is a member of liatrio-labs organization + check-org-membership: + runs-on: ubuntu-latest if: | ( github.event_name == 'issue_comment' && - contains(github.event.comment.body, '@claude') && - contains(fromJson('["OWNER","MEMBER","COLLABORATOR"]'), github.event.comment.author_association) + contains(github.event.comment.body, '@claude') ) || ( github.event_name == 'pull_request_review_comment' && - contains(github.event.comment.body, '@claude') && - contains(fromJson('["OWNER","MEMBER","COLLABORATOR"]'), github.event.comment.author_association) + contains(github.event.comment.body, '@claude') ) || ( github.event_name == 'pull_request_review' && github.event.review.body != null && - contains(github.event.review.body, '@claude') && - contains(fromJson('["OWNER","MEMBER","COLLABORATOR"]'), github.event.review.author_association) + contains(github.event.review.body, '@claude') ) || ( github.event_name == 'issues' && ( (github.event.issue.body != null && contains(github.event.issue.body, '@claude')) || contains(github.event.issue.title, '@claude') - ) && - contains(fromJson('["OWNER","MEMBER","COLLABORATOR"]'), github.event.issue.author_association) + ) ) + outputs: + is-authorized: ${{ steps.check.outputs.authorized }} + steps: + - name: Check authorization + id: check + env: + GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} + run: | + ACTOR="${{ github.actor }}" + + # Check if user is a repo collaborator/owner/member first + if [[ "${{ github.event_name }}" == "issue_comment" ]];
