rigor

v3.3.4

Verification-first workflows for finding real bugs, fixing them at root cause, and making measured improvements. Prove-it-or-don't-report-it: every finding carries an evidence tier and a proof artifact, and fixes ship a failing-then-passing regression test fixed at root cause. v2 adds test-suite validation (flaky + mutation testing), characterization safety nets, root-cause sibling sweeps, regression bisection, and a regression guard.

Included Skills9

bug-huntskills/bug-hunt/SKILL.md

Use when you want REAL bugs found and proven, not a list of guesses. Each candidate is proven with a failing test. The flagship.

deep-reviewskills/deep-review/SKILL.md

Use for pre-merge review of a PR or diff. bar verified (default) blocks only on CONFIRMED defects; bar standard reviews every lens; unproven items are advisory.

fix-verifiedskills/fix-verified/SKILL.md

Use when CONFIRMED bugs exist and you want them fixed at root cause with proof. Requires CONFIRMED findings as input.

ground-truthskills/ground-truth/SKILL.md

Use first, for the factual baseline before any analysis. Runs the real toolchain and captures ground truth plus a coverage and blind-spot map.

improve-measuredskills/improve-measured/SKILL.md

Use for measured, behavior-preserving improvements, not speculative refactors. For profiling-led hot-path optimization, use code-ops-suite:performance.

quality-scanskills/quality-scan/SKILL.md

Use when you want high-signal, defect-causing quality issues with evidence and tiers, not cosmetic nits.

regression-huntskills/regression-hunt/SKILL.md

Use when something used to work and you need to pinpoint the commit that broke it and find related regressions in recent changes.

safety-netskills/safety-net/SKILL.md

Use before refactoring or fixing low-coverage code. Writes characterization tests that lock current observable behavior.

test-suite-auditskills/test-suite-audit/SKILL.md

Use when you need to know whether a green suite actually catches faults. Validates the tests other proofs rest on.
