docs(rules): record CI-classification and verification lessons from the raw-lane close-out - #30079
Conversation
Add two rules distilled from the raw-query campaigns: - ci-failure-classification: classify CI failures from evidence (frozen install first, non-inert control experiments, known flake fingerprints, gate-vs-content diagnosis). - non-vacuous-verification: every check must be able to fail (regression tests red pre-fix, verifiers fail on empty input, not.toBeAny sentinels, comments are not evidence). Extend typescript-patterns (keyed-union id parameters, ReturnType of overloaded functions), adr-writing (maintain the ADR in the PR that changes the decision), and the record-upgrade-instructions skill (stacked-PR entry placement, release-cut corollaries, token-precise detection predicates). Raise the total-rules-bytes footprint threshold to cover the two new rules. Always-apply and AGENTS.md budgets are unchanged.

📝 WalkthroughWalkthroughThe pull request adds repository guidance for verification, CI failure classification, ADR maintenance, TypeScript overloads, and upgrade recording. It indexes the new rules and raises the rules-footprint threshold. ChangesAgent guidance updates
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The documentation changes still prescribe validation steps that can compare the wrong branch base or miss ignored files, and related upgrade-recording guidance remains inconsistent about paths and coverage entries. Future contributors could therefore produce incomplete records that pass the documented checks, so follow-up is needed before merge. Possibly related PRs

The two new rulecards set alwaysApply: false without globs, so nothing said where they apply. Give each the surface it governs: the CI rule the workflow and script trees, the verification rule the test files. The ReturnType note claimed any added overload retypes consumers. Only the last signature does, since that is the one ReturnType resolves. The upgrade-instruction skill still diffed against origin/main in every step while the paragraph above them says the gate diffs against the branch the PR targets. Name that branch once and use it throughout. Move the detection-predicate patterns into a fenced block: a regex ending in a backtick cannot sit in an inline code span.

Line 22 correctly requires the same steps. Line 23 then calls a concurrent trivial PR with an identical signature “equivalent evidence.” A matching signature does not prove the same merge base, lockfile, setup action, runner, path filters, or other inputs. The workflow in
.github/workflows/ci.ymlalso runspnpm install --frozen-lockfile, build, and clean-tree checks at Lines 39-49.Line 32 has the same overstatement. Recurrence can indicate a timing-sensitive defect, but it can also repeat an infrastructure or dependency failure. Require the listed controls before classifying the failure as a PR defect.
Proposed wording
- a concurrent trivial PR ... with the identical signature is the equivalent evidence. + a concurrent trivial PR ... with the identical signature is corroborating evidence; + require matching workflow inputs before using it as a control. - a "flake" recurring on consecutive runs of the same tree is a real defect in a timing costume. + a "flake" recurring on consecutive runs of the same tree is evidence of a possible + timing-sensitive defect; confirm it with controls before classification.Also applies to: 32-32

…runnable The intro, routing table and reference section pointed at skills/upgrade/ and skills/extension-author/, which do not exist. The trees are skills/prisma-next-upgrade/ and skills/prisma-8-extension-upgrade/, which is also what the coverage gate scans and what the worked example already said. The install commands now match the invocation the published skills' own READMEs document. Validation step 4 compared the branch diff against the working-tree diff after re-applying the entry. The working tree is back at HEAD by then, so that comparison can never hold. Check that nothing is left over instead, and give the extension flow the same command rather than prose.

A diff against HEAD says nothing about files the entry created, so a stray artefact passed step 4. Ask git status for the substrate instead: an empty porcelain listing covers both the modification and the untracked cases in one command. Also name the extension skill's SKILL.md where the text said 'the matching extension-author file'.

Close-out documentation from the whole-query raw SQL project (TML-3198 → TML-3214/TML-3217 and the CI work they surfaced: TML-3221, TML-3222). Records the durable lessons as rules and skill guidance.
New rules
ci-failure-classification.mdc— classify CI failures from evidence before acting: runpnpm install --frozen-lockfilebefore classifying (stale dist/deps/fixtures fake both reds and greens), use control experiments that actually run the failing steps (the inert-diff detector makes docs-only controls vacuous), and recognize the flake fingerprints this project hit live: assertion drift across retries, connection death cascades (one error, then siblings at 0ms), and all-tests-green-but-exit-1 teardown rejections. Also: when a gate demands content about changes a PR does not contain, suspect the gate's comparison base.non-vacuous-verification.mdc— every check must be able to fail. Regression tests run red pre-fix or test a purpose-built seam; verifiers fail on empty input;not.toBeAny()sentinels guard type fixtures againstskipLibCheckany-poisoning; comments describing guards are not evidence the guard exists; generated-file claims are tested by regenerating.Both are scoped (
