C-checklist

C-checklist is an agent for coding agents from lukacf/meerkat. It costs 0 tokens per session (456 once invoked), scanned A, original, Apache-2.0.

A checklist for Meerkat, a modular agent framework written in Rust, covering how untrusted incoming messages are admitted and how trust changes are handled.

In plain words
What is it for?
Use it to review ingress admission, acknowledgements, trust publication, rollback behavior, and related handler tests.
Why use it?
It gives developers concrete conditions for checking that authentication and trust decisions happen in one place and remain correct after failures.

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

C-checklist 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 4d 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 it actually says

Lane C Checklist

  • C-01 DOGMA-12 Make classified admission the single semantic owner of untrusted ingress decisions. Done when transport does not independently decide the same untrusted-ingress fact.
  • C-02 DOGMA-12 Preserve auth-exempt bootstrap/idempotency traffic through the single-owner admission path. Done when auth-exempt bridge traffic is accepted or dropped only by the canonical admission seam.
  • C-03 DOGMA-12 Move ack emission after final admission outcome. Done when no ack is sent before admission has definitively accepted the ingress item.
  • C-04 DOGMA-12 Remove trust rereads for the same ingress fact. Done when the trust decision is computed once and reused through classification/admission.
  • C-05 DOGMA-19 Publish trust only after DSL bind success. Done when bind rejection cannot leave a peer trusted.
  • C-06 DOGMA-19 Keep old trust active until DSL authorize success and publish new trust only after success. Done when authorize rejection cannot strand the wrong supervisor as trusted.
  • C-07 DOGMA-19 Add explicit rollback or deferred-publication logic for every trust-mutating failure path. Done when handler-level tests cover reject-after-prepare cases.
  • C-08 DOGMA-12 DOGMA-19 Add or update the trust/ack defensive scan. Done when the scan is checked in and wired for lane/final gating.
  • C-09 Self static review. Done when the trust publication order is clearly commit-first and not just renamed comments.
  • C-10 Handoff note. Done when handoff commit, changed files, and risks are recorded in C-plan.md.
  • C-11 Generated-output request. Done when any regen need is recorded explicitly, or marked none.

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.

C-checklist is an agent published in the GitHub repository lukacf/meerkat (20 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 456 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
