Use when generating AI cover images or illustrations via OpenRouter API (AI image, OpenRouter, cover image, WeChat, text-to-image, Gemini, image generation).
Use when an approved delivery slice or plan exists and the next step is execution, or when debugging, TDD, E2E acceptance, parallel task coordination, or isolated workspace setup is needed (approved slice, approved plan, coordinated execution, implementation execution, worktree, isolated workspace, branch isolation, plan execution, TDD, test first, failing test, bugfix, regression proof, E2E, end-to-end, acceptance test, test suite, acceptance gate, parallel agents, subagent, independent task, coordinator, debugging, root cause, unexpected behavior, verification failure).
Use when drafting or revising technical design, API endpoint contracts, or advancing a service from evidence into design and implementation readiness (technical design, backend design, platform design, module boundary, API design, endpoint contract, validation, error code, service delivery, design closure, implementation readiness).
Use when researching a topic, discovering or clarifying requirements, tracing evidence, or investigating a technical spike (research, investigation, topic research, technology evaluation, domain analysis, findings report, requirements discovery, elicitation, requirements document, feature definition, use case analysis, requirement clarification, scope definition, acceptance, functional boundary, evidence trace, traceability, data mapping, reference mapping, technical spike, evidence gap, option comparison).
Use when splitting scope into executable implementation slices, or when strengthening test and acceptance coverage (implementation breakdown, delivery slices, task decomposition, test breakdown, acceptance, integration test, verification planning).
Use when renaming, moving, archiving, or cleaning up docs (archive, move, rename documents).
Use when rendering Mermaid syntax into diagram image files for docs or articles (mermaid, flowchart, diagram, PNG, SVG, visualization).
