**Plan Context**: Layer 0 (SDLC-Agnostic), Layer 1 (Language-Specific), Layer 2 (Stack/Goal-Specific), ARL Meta-Layer  
**Generated**: 2026-02-23

## Layer 0 (SDLC-Agnostic)

### backlog-item-groomer

- **Type**: agent
- **Path**: `.claude/agents/backlog-item-groomer.md`
- **Proposed Layer**: L0
- **Relevance**: Produces context manifest with RT-ICA assessment, dependency graph, and blockers. Core to SAM planning pipeline and human touchpoints before task delegation.
- **Key content**:
  - RT-ICA procedure: Goal statement → Reverse prerequisites → Availability check (AVAILABLE/DERIVABLE/MISSING) → BLOCKED/APPROVED decision
  - Discovers supporting skills, related agents, prior work, dependencies, blockers
  - Output format: Context Manifest with RT-ICA Summary, Supporting Skills, Related Agents, Prior Work, Dependencies, Blockers, Suggested First Steps
  - Uses Glob/Grep/Read only; no write tools; orchestrator owns commits

### fact-checker

- **Type**: agent
- **Path**: `.claude/agents/fact-checker.md`
- **Proposed Layer**: L0
- **Relevance**: Implements verification protocol and evidence discipline. Returns VERIFIED/REFUTED/INCONCLUSIVE with citations. Training data recall explicitly rejected.
- **Key content**:
  - Mandatory tool usage: WebFetch, WebSearch, gh, CLI — must use at least one before verdict
  - Chain of Verification (CoVe): 2–3 falsification questions, cross-check with different source/method
  - Structured verdict format: CLAIM, VERDICT, EVIDENCE, CROSS_CHECK, EXPLANATION, CITATION
  - Prohibited: VERIFIED/REFUTED without tool evidence; phrases "I know", "from my training"
  - Single-claim scope; does not update backlog or fix docs

### topic-specialist

- **Type**: agent
- **Path**: `.claude/agents/topic-specialist.md`
- **Proposed Layer**: L0
- **Relevance**: Embodies evidence discipline and CoVe for domain research. Primary sources only; can update/create skills with verified findings.
- **Key content**:
  - Invocation format: TOPIC, SKILLS, QUESTION, CONDITIONS, OUTPUT (answer only | update skill | create skill)
  - Source priority: GitHub source → README/docs → issues → official docs → WebSearch
  - Minimum research checklist: repo URL, README, main entry point, GitHub issues
  - CoVe step: 2–3 falsification questions, cross-check, revise if discrepancy
  - Evidence rules: Never state fact without URL + access date; no "I know", "typically"; quote directly
  - Boundaries: No training-data-only responses; no commits; modifies only skills/research

### context-gathering

- **Type**: agent
- **Path**: `.claude/agents/context-gathering.md`
- **Proposed Layer**: L0
- **Relevance**: Creates context manifest for new tasks. Human touchpoint for task prep; ensures developer has everything needed before implementation.
- **Key content**:
  - Process: Understand task → Research everything (spare no tokens) → Write narrative context manifest
  - Output: "How It Currently Works" (verbose narrative), "For New Feature Implementation", "Technical Reference Details"
  - CRITICAL: May ONLY use Edit on the task file; forbidden from editing other files
  - Self-verification: "Could someone implement with ONLY my context manifest?"
  - Architecture patterns, data access, code organization, business logic extraction

### context-refinement

- **Type**: agent
- **Path**: `.claude/agents/context-refinement.md`
- **Proposed Layer**: L0
- **Relevance**: Updates context manifest with discoveries from work session. Only updates if drift or new discoveries found. Accumulates institutional knowledge.
- **Key content**:
  - Process: Read transcript → Analyze for drift/discoveries → Decision (no update vs. update)
  - Drift types: Component behavior different, gotchas, hidden dependencies, wrong assumptions, environmental requirements
  - Update format: "Discovered During Implementation" with narrative + Updated Technical Details
  - Qualifies: Undocumented interactions, incorrect assumptions, hidden side effects; NOT minor typos, temporary workarounds

### logging

- **Type**: agent
- **Path**: `.claude/agents/logging.md`
- **Proposed Layer**: L0
- **Relevance**: Consolidates work logs into task Work Log section. Artifact conventions for task format; invoked during context compaction or task completion.
- **Key content**:
  - Responsibilities: Read target file + transcript → Assess cleanup → Remove outdated → Update existing → Add new → Chronological order
  - Work Log format: Date → Completed, Decisions, Discovered, Next Steps
  - Rules: Cleanup first, chronological integrity, consolidation, clarity
  - CRITICAL: May ONLY edit the specific task file; never sessions/state/, current-task.json, system state
  - Scope: Work Log, Success Criteria, Next Steps, Context Manifest

### code-review

- **Type**: agent
- **Path**: `.claude/agents/code-review.md`
- **Proposed Layer**: L0
- **Relevance**: Quality gate for code changes. Invoked explicitly or by protocol. Reviews for security, bugs, performance, project patterns. LLM-slop detection.
- **Key content**:
  - Use ONLY when explicitly requested or by protocol in sessions/protocols/
  - LLM slop focus: Reimplementing existing, failing norms, junk patterns, placeholders, hallucinated defaults, duplicate env vars
  - Categorization: Critical (blocks deployment), Warning (should address), Suggestion (consider)
  - "Keep it real": Consider actual risk; don't concern troll
  - Output: Summary, Critical/Warning/Suggestion sections, Patterns Followed, Overall Assessment

|-------|--------|
| **L0** | backlog-item-groomer, fact-checker, topic-specialist, context-gathering, context-refinement, logging, code-review |
| **L1** | javascript-pro, typescript-pro, c-systems-programmer |

## Cross-Cutting Patterns

1. **Evidence discipline**: fact-checker, topic-specialist — primary sources only, CoVe, citations
2. **RT-ICA**: backlog-item-groomer — pre-planning gate, AVAILABLE/DERIVABLE/MISSING
3. **Context manifest**: backlog-item-groomer, context-gathering, context-refinement — task format artifact
4. **Orchestrator boundaries**: Most agents defer commits, README updates, batch coordination to orchestrator
5. **Project detection**: L1 agents (javascript-pro, typescript-pro, c-systems-programmer) read config files before acting
6. **Stack-specific skills**: plugin-assessor, plugin-docs-writer load claude-skills-overview-2026, claude-plugins-reference-2026, claude-hooks-reference-2026
