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 | $0.00350 | $0.00350 |
| Opus 5 | $0.00175 | $0.00175 |
| Sonnet 5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
onesub 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 6d 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
Claude Code Instructions
@AGENTS.md
AGENTS.md is the canonical repository guide shared with Codex. Update that file instead of
duplicating project structure, commands, or coding rules here. This file holds only notes about
using Claude Code in this repository.
Working here with Claude Code
- Orient before editing.
AGENTS.md→ Source Map tells you which file to open; Start Here by Task tells you what a given task touches. Prefer that over a repo-wide grep. - Plan first for cross-package work. Anything that touches
packages/shared/src, a route, or a persisted field fans out into several files — sketch the file set from the Contract Change Checklist before the first edit. - Long commands.
npm ciand a fullnpm run buildtake minutes; raise the Bash timeout rather than letting them be killed.npm test -- <path>is the fast inner loop. - Verify what you changed, not everything. Use the "Touched → Run" table in Change Workflow.
Say explicitly which checks you ran and which you could not (this checkout may have no
pwsh, no network, and no store credentials). - Never commit, push, or release unless asked. See Do Not Do These Without Being Asked. The working tree often carries the user's own in-progress changes — leave them intact.
- Reviews.

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.
