checkpoint-aggregator

checkpoint-aggregator is an agent for Claude Code from arbiterForge/codeArbiter. It costs 34 tokens per session (956 once invoked), scanned A, original, AGPL-3.0.

A software agent that combines finding-triage results and decision-challenger results into one dated checkpoint document. A checkpoint is a saved record of the project’s current review state.

In plain words
What is it for?
Use it to create .codearbiter/checkpoints/YYYY-MM-DD.md after the relevant review outputs are available.
Why use it?
It keeps related review outputs together in a predictable location and date-based format. It reports findings but does not block work by itself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

checkpoint-aggregator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
