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 | $0.12699 | $0.12699 |
| Opus 5.5 | $0.05080 | $0.05080 |
| Sonnet 5.5 | $0.02540 | $0.02540 |
| Haiku 4.5 | $0.01270 | $0.01270 |
Grade A, and why
shipit 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 today.
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 — 321 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
ShipIt is a browser-based AI editor — describe what you want in chat, the agent writes the code, and you see results live. The agent runs as a CLI inside a session container; Claude Code CLI is the default backend, Codex CLI is also supported, and the architecture is agent-agnostic so additional backends can be added later. Authentication normally uses the user's existing subscription with the chosen provider; a metered API key exists only as a fallback ranked below connected accounts.
Product principles
These govern what ShipIt is. They override convenience, "what other tools do," and "this is how the underlying platform works." A proposal that conflicts with one is wrong. Design docs cite them by number — §1–§5 are stable identifiers; compress the prose, never renumber.
1. ShipIt is the surface. The user does not leave it.
You build, review, ship, and debug inside one chat-shaped IDE. PRs, CI status, deploy status, diffs, commit history, conversation history, terminal output, preview, and merge conflicts all surface inline — no GitHub tab, hosting dashboard, CI tab, or local terminal required. Sending the user elsewhere is a failure of the product, not a feature.
2. Inline beats link-out. Always.
If the upstream system has the data, ShipIt fetches and renders it. Links to GitHub or the cloud provider are escape hatches in overflow menus, never the happy path — "View on GitHub" sits beside the PR card, and we never bounce anyone to GitHub's diff viewer. The reason is compounding: once the user is reading a PR on github.com, the next comment, re-request, and fixup happen there too. The cycle has to start somewhere; we keep it inside.
3. External tabs are reserved for things ShipIt does not own.
The whole list: OAuth / auth flows (Anthropic, GitHub own their login screens), account and billing pages (provider billing, GitHub repo creation and settings), and external documentation the user explicitly clicks through to. "The PR was created so let's open it" is not on it.
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.

shipit CLAUDE.md is an instructions file published in the GitHub repository nikzlabs/shipit (9 stars, last pushed today), licensed Apache-2.0. It adds 12,699 tokens to every session, about $0.0508 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
