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

reapfield 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 8d 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

AGENTS.md

Guidance for AI coding agents working in the reapfield repository.

Everything you need is in CONTRIBUTING.md. Read it before changing anything. It is self-contained.

The short version

uv sync                    # install
uv run pytest              # offline: no network, no API key needed
uv run ruff check .        # lint
uv run pyright reapfield   # types

Two rules that override anything else you infer

  1. No code path may special-case a field name. No KNOWN_FIELDS table, no per-field heuristics. test_field_names_are_arbitrary enforces it.
  2. Never add anti-bot evasion. No fingerprint spoofing, CAPTCHA solving, header randomisation, or proxy rotation. When a site refuses, reapfield stops.

Commits

Conventional Commits are mandatory — release-please generates the changelog from them. See CONTRIBUTING.md for the full bump table.

Changes

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.
