hallow-assurance

Verification in proportion to criticality. Hooks call the assure CLI to block agent edits to protected files and role-violating edits, inject the repo's level map at session start, and block stopping while changed code fails its fast objectives. Inert in repos without an assurance.yaml.

Included Skills3

assure-testingskills/assure-testing/SKILL.md

How to write tests in a repo governed by hallow-assurance (an assurance.yaml at the root). Use when writing or changing tests, property tests, fuzz targets, or fuzz corpora; when reproducing a bug before fixing it; when assure check or assure evaluate reports a failing objective; or when uncovered code needs a coverage resolution.

bugfixskills/bugfix/SKILL.md

Fix a bug fail-first — a verifier reproduces it with a failing test, an implementer fixes it.

checkskills/check/SKILL.md

Run the hallow-assurance fast check on the working tree, then optionally the full evaluation.
