Read a plan file, execute every task in dependency order with per-task validation, then write an implementation report to reports/<feature-slug>-implementation-report.md.

Analyze a ticket or feature description, read the codebase, identify risks, and write a context-rich implementation plan to plans/<feature-slug>-plan.md. No code is written in this phase.

Delegate the latest implementation diff to the code-reviewer sub-agent for a PASS/CONCERNS verdict against CLAUDE.md rules, then write the verdict to reports/<feature>-review.md.

Run the full quality gate (ruff + mypy + pytest + tsc + vitest) and report PASS/FAIL for each command. Run before any commit or PR.
