Store raw results under `.agents/evidence/` or a documented benchmark directory; summarize with\n   median, p95 and confidence interval.\n8. Keep the benchmark and the baseline config in the repository so the next agent can reproduce it.\n\n## Verification\n\n- Before/after runs use the same machine, build profile, dataset and command.\n- At least 5 samples; report median and p95, not only the best run.\n- The improvement exceeds run-to-run noise; show the distributions.\n- Correctness and security checks still pass.\n- The benchmark command is documented and, where practical, automated.\n- Regression claims are reproducible by a second person/agent.\n\n## Failure and escalation\n\n- Noisy environment: increase samples, pin resources, or move to an isolated runner; otherwise mark\n  the result inconclusive.\n- Benchmark harness is wrong (dead-code elimination, missing I/O, unrealistic data): fix the harness\n  before trusting numbers.\n- Improvement is within noise: report \"no measurable change\"; do not ship complexity for it.\n- Performance requires a design change or new dependency: escalate with the measured trade-off.\n- Production profiling needs credentials or traffic: require explicit approval and a safe sampling\n  plan.\n\n## Done when\n\nA reproducible baseline, bottleneck evidence, measured change, correctness results, variance and\nresidual risk are reported; raw data is retained; no unmeasured performance claim remains.\n"

Use when preparing a version, artifact, app build, package or deployment; when checking provenance, signatures, compatibility, security findings, rollback and final evidence.\n---\n\n# Release verifier\n\nA release is a claim that a specific artifact is fit to ship. Verify the artifact, not the branch\nyou remember testing. Shipping requires human approval; this skill prepares the evidence.\n\n## Activate when\n\n- Preparing a tag, package, binary, container, app build or deployment.\n- A release checklist or signing/provenance step is required.\n- A rollback plan must be validated before a production change.\n\n## Inputs and assumptions\n\n- The exact revision and artifact digest to release.\n- The release policy: versioning, changelog, signing, provenance, supported platforms, compatibility\n  window, approval owners.\n- Credentials for signing/publishing must be injected at runtime; none are read from the repository.\n\n## Outputs\n\n- A release evidence bundle: revision, artifact hashes, full-gate result, security result, SBOM or\n  dependency inventory where available, signature/provenance status, compatibility results.\n- A changelog and version check consistent with the artifact.\n- A tested rollback procedure and an owner.\n- An explicit list of unverified items and residual risks.\n\n## Permissions and restrictions\n\nDo not publish, tag, sign, deploy or rotate credentials without explicit human approval. Do not\nrelease from a dirty tree or an unverified artifact. Do not skip a failed check to meet a date; do not\nedit the changelog to hide a breaking change. Never commit signing keys or tokens.\n\n## Workflow\n\n1. Freeze the candidate: exact commit, clean tree (or documented dirty build), artifact digest.\n2. Run `./.agents/bin/eng verify --profile full --ci`. Confirm the evidence record is for the\n   candidate revision, not an earlier one.\n3. Run `./.agents/bin/eng release-check --version <v> --artifact <path> --notes <file> --rollback <file>`.\n   It refuses a dirty tree, missing version/notes/rollback, or evidence for another HEAD.\n4. Verify the version, changelog, compatibility notes and migration steps. Check that generated\n   artifacts match their source.\n5. Check security: required scanners ran, findings are resolved or explicitly accepted by the owner,\n   dependency/license policy is satisfied.\n6. Verify artifact integrity and provenance: hashes, signatures, SBOM, reproducible build or\n   attestation. Record what is unavailable.\n7. Test the rollback on a copy or staging environment; record the command and expected state.\n8. Obtain human approval for the publish/deploy step. Publish through the approved channel.\n9. After publishing, verify the public artifact hash/signature and a smoke test. Record the result.\n\n## Verification\n\n- Evidence is bound to the released digest, not just a branch name.\n- All required checks pass; skipped/blocked checks are listed and accepted explicitly.\n- Version and changelog match the artifact.\n- Signing/provenance verified with the project's public key/policy where available.\n- Rollback was exercised, not merely described.\n- Public artifact re-downloaded and hash-checked after upload.\n\n## Failure and escalation\n\n- Dirty tree or mismatched digest: stop; rebuild from the tagged revision.\n- Required check blocked: do not release; report the blocker and owner.\n- Security finding unresolved: stop; require an explicit risk acceptance from the owner.\n- Signing key or credential unavailable: stop; do not substitute an unsigned artifact silently.\n- Post-publish verification fails: trigger rollback, preserve evidence, notify the owner.\n\n## Done when\n\nThe exact artifact is identified and hashed, the full gate and security checks have evidence, the\nchangelog/version/compatibility are consistent, rollback is tested, human approval is recorded, and\nremaining risks are stated.\n"
