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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00889 | $0.00889 |
| Opus 5.5 | $0.00356 | $0.00356 |
| Sonnet 5.5 | $0.00178 | $0.00178 |
| Haiku 4.5 | $0.00089 | $0.00089 |
Grade A, and why
agents-shipgate 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 2mo 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 — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Instructions
The full agent-facing instructions for this repo live in AGENTS.md. Everything there applies to Claude Code.
A few Claude-specific notes:
Running the CLI in this repository
Use ./shipgate <command> ... from the repository root — the repository launcher, and the canonical command here (python shipgate <command> ... on Windows, which does not read a shebang). It is the same CLI as agents-shipgate, but it runs this working tree's src/, picks a supported interpreter (the main checkout's virtualenv when you are in a git worktree), and needs no install and no PYTHONPATH. The recovery commands it prints name the launcher, so you can run them as printed.
A bare agents-shipgate may resolve to a different, older install on PATH, or fail with ModuleNotFoundError if the environment behind it is gone. Use it only to check what an installed build does. If a command behaves as though an edit never happened, run ./shipgate doctor --config shipgate.yaml --json and read the environment block — it names the interpreter, the imported package, the checkout, and any mismatches[].

Output handling
Prefer --json on every command and parse the result programmatically. Do not scrape stdout when a JSON form exists. The stable JSON shape is the contract.
For scan, parse agents-shipgate-reports/report.json directly — that's where the structured output lives. The stdout summary is for humans.
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.
