Use when the user wants a security review of code or a diff — OWASP/CWE findings with severity, taint/data-flow analysis, and concrete fixes via security_review
Use when the user wants tests generated for code or a diff — enumerates edge cases and failure modes first, then emits runnable test code via testgen
Use when a task would benefit from a structured thinking technique but you're not sure which — recommends the right prompt technique for the intent (debug, spec, refactor, decision, design) and applies it
Use for decisions or judgments worth multiple independent perspectives — multi-model council with parallel analysis, search grounding, and synthesis (30-60s); for a quick single-call verdict use the jury tool directly
Use when the user shares or finishes a plan and wants it stress-tested before execution — adversarial multi-model pre-mortem with ranked risks, mitigations, and concrete plan edits
Use when code changes are ready for review — a diff exists, the user says "review my changes/PR", or a commit is about to happen. Multi-model diff review (Kimi, DeepSeek, GPT-5.5 panel + Gemini judge) with a MERGEABLE verdict
Use when TachiBot tools seem missing, a provider isn't working, or the user asks to set up/configure TachiBot or its API keys — runs doctor and walks through fixing the gaps
Use when a feature request is loose or ambiguous and needs a reviewable spec before planning — turns "add X somehow" into user stories, acceptance criteria, out-of-scope, and open questions via spec_writer
