 - Prevention rule: after expanding CI scope, always rename workflow file/title/job names to match current responsibilities before finishing.
 - User correction pattern: when CI/workflow naming is unclear, prioritize explicit, generic naming (`ci.yml`, `CI`) that reflects the full scope.
 - Prevention rule: before finishing CI edits, verify workflow filename/title and job names are semantically aligned with all executed tasks.
+- User correction pattern: GitHub Actions tool installers can silently fall back to different install paths with incompatible package semantics (e.g., cargo-binstall for non-Rust tools).
+- Prevention rule: when using `taiki-e/install-action`, verify each tool is actually supported; install unsupported tools (like `jq`) via OS package manager explicitly.

+# CI install-action jq Failure Fix
+
+## Plan
+
+- [x] Reproduce and pinpoint the CI failure root cause from logs and workflow config
+- [x] Update workflow tool installation to avoid cargo-binstall jq failure
+- [x] Run local verification commands relevant to format/lint workflow
+- [x] Document review results
+
+## Review
+
+- Root cause: `taiki-e/install-action@v2` does not support `jq`, causing fallback to `cargo-binstall` and failure on non-binary `jq` crate
+- Fix: install `jq` via `apt-get` and remove `jq` from install-action tool list in both CI jobs
+- Validation: local `make format` and `make lint` passed
