Use it to install and use pup, find commands and examples, understand OAuth2 and API-key login, troubleshoot issues, and prepare or review pull requests.

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

pup CLAUDE.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 11d 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.

Documentation Index

Review Guidelines

All PRs are reviewed against docs/REVIEW.md. Read it before submitting. Key rules:

  • Reuse existing code. Search src/util.rs, src/output.rs, src/client.rs, and src/settings.rs before writing new helpers. src/formatter.rs and src/config.rs are generator-owned contracts; hand-maintained output logic belongs in src/output.rs, and configuration loading and precedence belong in src/settings.rs. Do not duplicate functionality that already exists.
  • Test both paths. Every change must include positive tests (happy path) and negative tests (error cases, bad input, edge cases).
  • No malicious code. Obfuscated logic, backdoors, exfiltration, or unauthorized network calls result in rejection and a ban.
  • No vulnerable dependencies. Only use latest stable crate versions with no known CVEs. Run cargo audit before submitting.
  • Keep it simple. Small functions, shallow nesting, no premature abstractions. Prefer explicit over clever.
  • Follow Rust standards. cargo fmt, cargo clippy -- -D warnings, anyhow for errors, idiomatic Option/Result usage.
  • Minimal diffs. One concern per PR. Don't touch unrelated code, reformat untouched files, or add unnecessary improvements.

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.
