dh

Produce groomed content for a backlog item — discovers related skills, agents, prior work, and dependency graph; performs RT-ICA assessment; outputs groomed item template for writing into .claude/backlog/{priority}-{slug}.md. Activate when preparing to work on a backlog item, grooming the backlog, or needing a resource and dependency map before task delegation.

SAM Stage 6 independent code reviewer. Reviews any language or stack against a SAM task file's acceptance criteria. Detects the stack from files, loads the matching dh:code-review-{stack} skill, checks universal quality dimensions (security, correctness, tests, API contracts, naming, error handling, performance), produces a structured PASS/FAIL/NEEDS-WORK verdict, and registers the report as a codebase-analysis artifact via MCP. Use when a task reaches S6 Forensic Review or when an independent review of implementation quality is required. Trigger phrases: 'review this implementation', 'run code review', 'S6 review', 'forensic review', 'check implementation against acceptance criteria'.

Explores codebase patterns and writes structured analysis documents. Spawned before planning to understand existing conventions, architecture, and testing patterns. Writes documents directly to reduce orchestrator context load.

Updates task context manifest with discoveries from current work session. Analyzes implementation code and task file to understand what was learned. Only updates if drift or new discoveries found. Provide the task file path.

Post-task verifier that compares method signatures and type contracts from the architect spec against files modified by the just-completed task. Reads the architect spec Component Design and Type System Design sections, extracts expected signatures and contracts, then greps the modified files to find actual signatures. Reports mismatches as a concerns block with CONTRACT VIOLATION (signature mismatch) and CONTRACT GAP (spec defines contract but implementation is silent) severity levels. Returns an empty response when no mismatches are found.

SAM-style feature initiation workflow: discovery -> codebase analysis -> architecture spec -> task decomposition -> validation -> context manifest. Use when a user asks to add a feature, plan a feature, or convert an idea into executable task files.

Use when analyzing failing test cases to determine whether failures indicate genuine bugs or test implementation issues. Activates on "analyze failing tests", "debug test failures", "investigate test errors", or when provided with specific failing test names or output. Applies balanced investigative reasoning — does not auto-fix tests without establishing root cause.

Single interface for backlog items and GitHub Issues. GitHub Issues are the source of truth. All backlog CRUD goes through MCP tools (mcp__plugin_dh_backlog__*) — no direct file edits. Use when creating, listing, viewing, updating, closing, resolving, grooming, or syncing backlog items and GitHub issues.

Combine CLEAR (Concise, Logical, Explicit, Adaptive, Reflective) and CoVe (Chain of Verification) to write and lint agent task files that will be executed by worker agents. Use when orchestration or planning agents are producing task plans, task prompts, or TASK.md style instructions that must be unambiguous, verifiable, and resistant to hallucination.

Claude Code skill and agent review patterns. Covers SKILL.md structure, frontmatter validity, token budget, description quality, and agent contract compliance. Loaded automatically when reviewing Claude skills or agent definitions.
