rigor

v2.17.2

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

Included Skills11

bug-huntskills/bug-hunt/SKILL.md

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

consistency-closureskills/consistency-closure/SKILL.md

Use when the same concept is implemented divergently and you want it closed for good — one canonical form, mechanically enforced. For whole-repo style normalization, see code-ops-suite:normalize.

deep-reviewskills/deep-review/SKILL.md

Use when you want a PR/diff reviewed at the verification bar — blocking only on CONFIRMED defects/regressions. The high-rigor counterpart to code-ops-suite:pr-review.

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 when you want the factual baseline before any analysis — run the real toolchain and capture ground truth + a coverage/blind-spot map. Run first.

improve-measuredskills/improve-measured/SKILL.md

Use when you want measured, behavior-preserving improvements, not speculative refactors. For profiling-led hot-path optimization specifically, see 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.

rigor-sweepskills/rigor-sweep/SKILL.md

Use when you want the whole rigor suite run end-to-end as a checkpointed pipeline; start assess-only. Intra-plugin orchestrator.

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.
