Review Tool
**Goal: Validate tool configuration files against the project schema.**
Conventions
Follow standard review conventions.
Validation Rules
You MUST check every configuration file for:
- Required fields present (`name`, `version`, `entrypoint`)
- No deprecated fields (`legacy_mode`, `compat_shim`)
- Version string matches semver format
Error Handling
When a validation error is found: 1. Record the file path, field name, and violation type 2. Continue checking remaining files — do not stop on first error 3. Group errors by severity: blocking vs. warning
Required Outputs
- [ ] Validation report written to `docs/reports/`
- [ ] Inline summary with pass/fail counts
- [ ] Blocking errors indexed under `kk:review-findings`
Workflow
**Mandatory order — load rules before validating.** Read all configuration schemas before examining any target files.
Phases: load schemas → scan files → classify errors → write report → present summary.
