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

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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Planning

Execute a multi-round planning session with architect/critic review.

Argument Routing

Argument Mode
<prompt> Self-execute on current host (default)
--delegate Add a review pass on <other-host> (see Review Phases for the mapping). On a host that is not itself a provider it replaces Phase 2 rather than adding to it, so the net is still one review phase.
round=N Review rounds for every applicable phase (default 1). e.g. round=3 for deeper iteration.
round=N,M Per-phase budget: Phase 1 (<other-host>) gets N rounds, Phase 2 gets M. Turns --delegate on.
--no-handoff Internal: skip implementation prompt at step 5 (caller controls next step)

Reviewers and the resolver always run in every review phase that dispatches — the round budget only sets how many times each phase iterates.

Parsing the round budget (round=… and --round=… are the same token):

  • round=N → every applicable phase gets N. Does not affect --delegate.
  • round=N,M{maxRounds[1]} = N, {maxRounds[2]} = M, and --delegate is on whether or not it was written. Phase 1 exists only under --delegate, so naming two budgets IS the request for both phases.
  • Absent → 1 for every phase.
  • Every value must be an integer ≥ 1. More than two values, a 0, or a non-integer is a usage error: report it and stop. Do not clamp, drop the extras, or fall back to the default.

Strip --delegate, the round token, and --no-handoff before passing the prompt to the execution path.

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.
