description: Periodic multi-reviewer sweep of the whole codebase — surfaces a triaged checkpoint report.
argument-hint: (none)

{{CMD:checkpoint}} — codebase sweep

Periodic sweep of the entire codebase with the reviewer fleet, funneled to a single dated report. Surfaces findings — not a promotion gate, enforces no sign-off.

Flow

1. Build the unit list — the same fleet as `{{CMD:review}}`, scoped to the whole codebase against the `{{PROJECT_DIR}}/.codearbiter/` docs:

| Reviewer | Reads | |---|---| | `security-reviewer` | `security-controls.md`; reviews security posture | | `auth-crypto-reviewer` | `security-controls.md`; authn/crypto/key/secret paths | | `dependency-reviewer` | dependency manifests; license + supply-chain posture | | `migration-reviewer` | migration history; safety + classification | | `coverage-auditor` | test coverage vs. obligations across the tree | | `architecture-drift-reviewer` | `decisions/`; drift between code and accepted ADRs |

2. Route to `dispatching-parallel-agents` (`{{PLUGIN_ROOT}}/skills/dispatching-parallel-agents/SKILL.md`) with that unit list (read-only batch). It dedupes, then funnels through `finding-triage` → `verdict-aggregator` and returns the single read-only verdict. 3. After the verdict returns, separately dispatch `checkpoint-aggregator` with that verdict. It writes the dated report to `{{PROJECT_DIR}}/.codearbiter/checkpoints/YYYY-MM-DD.md`: findings by severity with file:line, and out-of-scope items marked inline `[NEEDS-TRIAGE]`. 4. Write the current override **count** to `{{PROJECT_DIR}}/.codearbiter/last-checkpoint` — the integer baseline the {{IF:claude}}statusline{{ELSE}}startup briefing{{END}} subtracts for its overrides-since-checkpoint counter. The value is the number of non-comment, non-blank lines in `overrides.log` at this moment (`0` if the log is absent). This re-zeros the `over:N` segment until the next `{{CMD:override}}`. Write a bare integer, not a timestamp — the {{IF:claude}}statusline{{ELSE}}briefing{{END}} treats any value above the current total as stale and falls back to showing every override. 5. Report the checkpoint path.

Hard gate

Read-only except writing the checkpoint doc and `last-checkpoint` — MUST NOT modify code. MUST NOT consume raw reviewer output — only the `finding-triage` → `verdict-aggregator` verdict. Checkpoint persistence MUST remain the separate `checkpoint-aggregator` step and MUST NOT run for `{{CMD:review}}` or another generic parallel batch. MUST NOT resolve a `[CONFIRM-NN]` surfaced during the sweep by guessing. The report surfaces findings; it does not block or sign off anything.

When NOT to use

• Reviewing just the current diff → `{{CMD:review}}`.
• A pre-implementation threat model → `{{CMD:threat-model}}`.
• ADR health only → `{{CMD:adr-status}}`.
• A whole-codebase deep audit → `{{CMD:tribunal}}` (checkpoint is the lean periodic sweep; tribunal its rare deep counterpart).
