version: "1.0.1" name: ca-checkpoint description: Periodic multi-reviewer sweep of the whole codebase — surfaces a triaged checkpoint report. argument-hint: (none)

/ca-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 /ca-review, scoped to the whole codebase against the

<project-root>/.codearbiter/ docs:

1. Route to dispatching-parallel-agents (<plugin-root>/routines/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.

1. After the verdict returns, separately dispatch checkpoint-aggregator with that verdict and the reviewed commit from git rev-parse HEAD, the UTC review-start time, and whether the reviewed worktree was dirty. Retain these observed values from before the sweep. It writes the dated report to

<project-root>/.codearbiter/checkpoints/YYYY-MM-DD.md: findings by severity with file:line, and out-of-scope items marked inline [NEEDS-TRIAGE].

1. Write the current override count to <project-root>/.codearbiter/last-checkpoint — the

integer baseline the startup briefing 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 /ca-override. Write a bare integer, not a timestamp — the briefing treats any value above the current total as stale and falls back to showing every override.

1. 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 /ca-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 → /ca-review.
• A pre-implementation threat model → /ca-threat-model.
• ADR health only → /ca-adr-status.
• A whole-codebase deep audit → /ca-tribunal (checkpoint is the lean periodic sweep; tribunal its rare deep counterpart).
