| description | Skip Phase 7 rebuild when no code changed since Phase 5 build passed.
Compares git diff hash against stored hash from last successful build validation.
Triggers on: entering Phase 7, checking build status, before final build validation.
Returns BUILD_CACHE_HIT to skip or BUILD_CACHE_MISS to re-run build-validator.

Build Status Cache
Check whether a Phase 7 build-validator launch can be skipped because no code has changed since Phase 5 build validation passed.
When to Use
- After Phase 5 build passes: Stamp the cache
- At Phase 7 build check: Check the cache before launching build-validator
Usage
Stamp (after Phase 5 build passes)
bash ${CLAUDE_SKILL_DIR}/scripts/check_build_cache.sh <WORKDIR> stamp
Output: BUILD_CACHE_STAMPED
Check (before Phase 7 build)
bash ${CLAUDE_SKILL_DIR}/scripts/check_build_cache.sh <WORKDIR>
Interpreting Output
Cache Hit
BUILD_CACHE_HIT
Action: Skip the Phase 7 build-validator launch. Build was already validated and no code changed.
Cache Miss
BUILD_CACHE_MISS
reason: <why the cache is stale or missing>
Action: Run build-validator as normal.
How It Works
The script hashes git diff HEAD output (all uncommitted changes). After Phase 5 passes, this hash is stored. Before Phase 7 runs, the current hash is compared. If Phase 6 (visual QA) made code fixes, the hash changes and build-validator re-runs. If Phase 6 was skipped or made no code changes, the hash matches and build-validator is skipped.
