A-plan

A-plan is an agent for coding agents from lukacf/meerkat. It costs 0 tokens per session (1,121 once invoked), scanned A, original, Apache-2.0.

A work plan for one development lane in Meerkat, a Rust agent framework, focused on making turn-state snapshots and handles use the correct runtime authority.

In plain words
What is it for?
Use it to plan changes to the runtime loop, operation lifecycle, agent state and runner, turn-state contracts, handles, and Rust build checks.
Why use it?
It identifies the owned files, dependencies, checks, and safety scan needed to avoid relying on local turn state where runtime-backed state is required.

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

A-plan 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.

Requested Build Gate Commands

  • Quick probe:
    • ./scripts/repo-cargo check -p meerkat-runtime
    • ./scripts/repo-cargo check -p meerkat-core
  • Full gate:

Risks

  • DOGMA-08 and DOGMA-09 are structurally linked to DOGMA-13 through WaitingForOps
  • DOGMA-13 needs an honest runtime-backed integration test, not just local snapshot coverage
  • no compatibility shims are allowed in handoff commits

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.

A-plan 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 1,121 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.
