Create and drive a /board card as a mirror of a jira-task-runner run: born in triage, moved straight to in_progress, finished at in_review or done. The card MUST NEVER pass through the todo column -- see 'The load-bearing rule' below for why. Covers projectId…
Document an epic/feature architecture with the C4 model -- system context/container/component/dynamic diagrams as Mermaid .mmd plus a narrative doc. NOT for rendering an existing .mmd (use mermaid-viewer).
Generate or refresh the repo-wide architecture map — architecture-out/architecture-map.json (machine contract with named flows) + architecture-map.html (self-contained viewer). Use when the user asks for an architecture map, repo map, "/architecture-map", or…
Use when designing or reviewing Claude-based agent systems — agentic loops and stop_reason handling, multi-agent orchestration, coordinators, subagent invocation and context passing, workflow enforcement, Agent SDK hooks (PreToolUse/PostToolUse), task…
Use when setting up or auditing Claude Code in a repository — CLAUDE.md hierarchy and imports, .claude/rules, custom slash commands and skills, path-specific rules, plan mode vs direct execution, iterative refinement workflow, or CI/CD integration with…
Use when creating or reviewing tool definitions for Claude — tool names, descriptions, input schemas, structured error responses, tool_choice configuration, MCP server setup and scoping, or built-in tool usage (Grep, Glob, Read, Edit). Also when Claude picks…
Use when writing or reviewing system prompts, few-shot examples, structured output via tool use, JSON schema validation with retry loops, Message Batches API processing, or multi-instance/multi-pass review pipelines such as automated PR reviewers. Also when…
Use when reviewing long-running or multi-agent Claude systems for reliability — context window management and summarisation, escalation and ambiguity resolution, error propagation between agents, codebase exploration and context degradation, human review and…
