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

roadtrip-skill AGENTS.md scanned grade A with 1 finding 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 9d 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.

The opening of the file, as written. The whole thing — 290 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Universal Rulebook

Vendor-agnostic technical rules for working in this repo. Applies to any AI agent or human. For product/domain background see CONTEXT.md.

Branching Rule

  • When creating git branches, if current base branch is not default branch (main), you should prompt user to specify base branch
  • When submitting pull request (PR), you should set PR base branch as the current local base branch, instead of the browser github's default base branch

Hard constraints

  • Python 3.8+ standard library only for assets/, scripts/, and tools/. No third-party pip packages at runtime (urllib, json, re, math, …). Do not add runtime dependencies. Sole exception: mcp_server/ depends on the mcp SDK (declared in pyproject.toml) — never let it leak into the other dirs. Dev dependencies are pytest plus mcp for tests/test_mcp_server.py, which auto-skips when mcp is absent so the stdlib+pytest baseline stays green.
  • Zero required API keys. Everything must run and test with no keys and no network. Keys (NPS_API_KEY, OCM_API_KEY, OPENWEATHER_API_KEY) are read from env vars only and are strictly optional upgrades.
  • Use python3 (there is no python on the standard dev machine).

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.
