Evidence-bound investigation producing a falsifiable architectural mental model of a code concept, pattern, term, or component in large legacy codebases. Use WHENEVER user asks WHAT/HOW/WHERE about code — /explain, "explain X", "what is X", "how does X work", "trace this concept across layers", "preflight before bug-fix", "build mental model", "architectural overview", "layer-by-layer explanation", "F/B/D-XXX pattern explanation", or pastes a domain term or component name asking what it does ...

Pre-implementation blueprint for AI coding agents on legacy codebases. Use WHENEVER user asks HOW to implement, plan, or design — /howto.implement, /blueprint, "implementation plan / analysis / strategy / approach", "how to implement / add / build / refactor", pastes Jira / user story / RCA / SPEC asking "plan this", or mentions Tree of Thoughts, spec-driven development, Design-by-Contract. Falsification-first, anti-hallucination — Approach #0 baseline + 3+ alternatives, confidence-weighted Y...

Evidence-bound transformation of vague human requirements (Jira ticket, Confluence page, free text, file path) into AI-ready specifications for coding agents. Use WHENEVER user asks to /distill, "analyze requirements", "clarify task", "vague requirements", "ambiguous AC", "task vs bug", "EARS", "Given-When-Then", "GWT", "AI-ready spec", "prepare spec for implementation", "Open Questions", "INVEST", "MoSCoW", "user story analysis", "acceptance criteria", "steps to reproduce", "expected vs actu...

Root cause analysis for software bugs in large legacy codebases. Use this skill WHENEVER the user asks WHY a bug happens, asks for RCA, mentions root cause analysis, says /bug.why, /bug.investigate, asks "why is this failing", "find the root cause", "trace this exception", "investigate this bug", "post-incident review", or pastes a stack trace, error log, exception, NullReferenceException, SqlException, InvalidOperationException, or asks 5 Whys / Kepner-Tregoe / IS-IS-NOT / fault localization...

Surgical code-execution skill for AI coding agents on legacy codebases. Use WHENEVER the user asks to IMPLEMENT, CODE, BUILD, APPLY, or FIX from a contract source — IMP / Plan + TASK-NN, RCA report, freeform task, or Jira ticket. Triggers on /implement, /bug.fix, /code, /apply, /fix, "implement this", "code this", "build this", "apply this fix", "fix this bug", "execute the plan", "implement the blueprint", paths like `IMP-*.md`, `PLAN-*.md`, `RCA-*.md` followed by "implement"/"fix"/"apply", ...

Hypothesis-driven task-correctness verification for AI coding agents on legacy codebases. Use WHENEVER user asks to verify, audit, or pre-flight a task artifact (IMP, RCA, Plan, Implementation, Fix, Jira ticket) before submission — /verify, /verify-task, /gate2, "verify this", "verify the RCA", "verify the implementation", "is this fix correct", "double-check my plan", "audit before merge", "pre-flight before PR", "Gate 2 / Pre-Send check", "find what's wrong with my IMP", or pastes RCA-/IMP-...

White-box code-path tracing in two modes. REAL — empirical verification of completed code via CFG/MPC traversal, Counterfactual + optional Live Mutation Testing, PBT hook, Tandem-FL on FAIL, Killer-Path-First, FAIL-FAST, persistent index-prefixed JSONL trace with resume + confidence decay, Reviewer Agent re-rank, Reflexion lessons, structured fix_proposal + repro_snippet. VIRTUAL — pre-implementation falsification of RCA reports / Implementation Blueprints / Plans / freeform ideas via Planner...
