Prepare a hashlib release — changelog section, version bump, release-grade verification, bump commit — and hand the tag push to the maintainer. Also orchestrates the cross-repo cascade (convertlib → hashlib → cipherlib).

Measure hashlib performance properly — per-algorithm before/after comparison for optimization work, compiled-exe runs, correct interpretation. Use when optimizing, when asked "is this faster", to compare against crypto/pointycastle/hash, or before/after any change to a hot path ($update, $process, sink internals).

Implement a new hash/MAC/KDF algorithm in hashlib end-to-end — sink, wrapper, exports, cited test vectors, compare tests, benchmark, README row, changelog. Use when asked to add, implement, or port a hash algorithm, checksum, MAC, or KDF.

Run hashlib's CI gate locally, scoped to the current change — format, analyze, VM tests, plus node/integration/pana when the diff warrants them. Use before committing, when asked to "check", "verify", "preflight", or "is this ready", and as the final step of any code change.

Run the cipherlib release ritual — local pre-flight mirroring release-test.yml, CHANGELOG entry, single version-bump commit, matching vX.Y.Z tag, tag push, and CI watch through pub.dev publish. Use ONLY when the maintainer explicitly asks to release, publish, or bump the version.

Scaffold a new cipher algorithm, AES mode, or AEAD variant end-to-end in cipherlib house style — implementation, barrel wiring, canonical test file with KAT placeholders, integration parity, benchmark, README row, and CHANGELOG entry. Use whenever adding any new algorithm to this package.

Run cipherlib benchmarks and regenerate BENCHMARK.md plus its README embed safely, with the reference-machine guard. Use when measuring a performance change or when benchmark tables need refreshing.

The cipherlib verification gate — run after completing any change and before declaring it done. Ordered, fail-fast, CI-parity checks with a pass/fail report. Also covers when to add node-platform and integration runs.

Differential-fuzz every convertlib codec against external reference implementations (dart:convert, base_codecs, base32) with full-domain inputs and a reproducible seed. Use before releases, after touching any encoder/decoder or alphabet table, or when asked to "fuzz", "cross-check", or "audit" the codecs. Finds the class of bug that roundtrip tests structurally cannot (wrong-alphabet tables, masking errors).

Scaffold a new codec or a new alphabet variant for convertlib the house way - generated alphabet tables, codec class with static const instances, top-level to/from functions, the six standard test groups with differential checks, README/CHANGELOG/example updates, and exports. Use when adding any new encoding (a new baseN, a new alphabet like base58/base85/z85, or a new format codec).

Run the exact checks convertlib CI runs, locally, before any commit or release. Use before committing, when asked "is this ready", "run the checks", or as the first step of a release. Catches format drift, analyzer infos, vm/node test failures, and integration breakage without waiting 20 minutes for the GitHub Actions matrix.

Cut a convertlib release end to end - version choice, CHANGELOG, pubspec bump, atomic release commit, vX.Y.Z tag, push, CI watch, pub.dev verification, and the follow-up dependency bump in ~/projects/hashlib. Use when asked to release, publish, ship, cut a version, or tag. Prevents the tag/pubspec-mismatch failure that killed v3.1.1.
