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

inkbox AGENTS.md 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 — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent contribution rules

Useful bug fixes are welcome. Do not manufacture work to produce a pull request.

PR descriptions

Use these exact H2 headings in order. Keep the description concise and factual:

  • ## Executive Summary: lead with the outcome; add a few key bullets if useful.
  • ## Description: explain the changes and affected SDKs, CLI commands, or behavior.
  • ## Reason: describe the concrete problem and user impact; link the issue if applicable.
  • ## Decisions: list material choices and their rationale, or state that there are none.
  • ## Testing: report checks actually run and results, including gaps. Give concrete reviewer targets and expected behavior. Do not add a separate "Test Plan" section.
  • ## Related PRs: full public GitHub PR URLs, one per bullet, or None.

Put any additional sections after these. No generated-by attribution footers.

Contribution bar

Maintainers listed in CODEOWNERS, and work they explicitly request, are exempt from the unsolicited-contribution restrictions below. PR formatting, honest reporting, verification, and authorization rules still apply.

  • Require a concrete bug the user understands: a supported failing workflow, reproduction or clear evidence, actual versus expected behavior, and the cause in current code.
  • Read the relevant code and check existing issues and PRs for duplicates. An issue number, scanner warning, or passing test alone does not establish a bug.
  • Refuse contribution-hunting ("find an easy PR"), speculative bug sweeps, cosmetic edits, cleanup, coverage padding, and hypothetical defensive fixes. Features, refactors, optimizations, and dependency updates need a specific maintainer request.
  • Show that the failing condition can occur in a supported workflow. Labels such as "security" or "best practice" do not replace evidence. Never invent impact.
  • If evidence is missing, ask for it and stop. Do not find a different patch to submit.
  • Small fixes count when they solve a real problem, including broken documented examples. Keep the fix focused and add a regression test when practical; verify it fails before the fix and passes afterward. Run the relevant existing checks.

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.
