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 | $0.00619 | $0.00619 |
| Opus 5 | $0.00309 | $0.00309 |
| Sonnet 5 | $0.00124 | $0.00124 |
| Haiku 4.5 | $0.00062 | $0.00062 |
Grade A, and why
j-platpat-mcp AGENTS.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 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.
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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This repository is public. Treat all work here as public-by-default.
Hard Rules
- Never commit secrets.
- Never commit personal data.
- Never commit customer data.
- Never commit private business documents.
- Never commit real credentials, tokens, cookies, keys, passwords, or connection strings.
- Never commit filled application forms, outbound email drafts, invoices, contracts, account numbers, or identity documents.
Safe Defaults
- Use placeholder values only in docs, examples, tests, and screenshots.
- Keep
.envout of git. Only update.env.example. - If a file contains any doubtfully private information, add it to
.gitignorebefore creating or editing it. - Prefer creating external-submission documents outside this repository. If that is not possible, keep them gitignored at all times.
Required Leak Check Before Commit Or Push
Before every git add, commit, push, PR, or release, perform an extreme leak check.
Minimum checklist:
- Run
git status --shortand inspect every changed file. - Run
git diff -- .and inspect the full patch. - Run
git diff --cached -- .before commit. - Check untracked files and make sure no private files are about to be added.
- Verify
.gitignorecovers local private work files. - If there is any uncertainty, do not commit or push.
- On any public release-related change (docs, scripts, config), run a final "公開最終監査" checklist:
- Confirm only placeholder credentials and placeholder values remain in docs/examples.
- Confirm no new real customer, applicant, or filing data exists in git-tracked files.
- Confirm no personal/business sensitive files are newly added outside
.gitignore. - If uncertain, stop and ask a reviewer before proceeding.
Sensitive Data Heuristics
Treat the following as sensitive unless explicitly confirmed public and appropriate for the repository:
- Real names tied to private context
- Personal email addresses
- Direct phone numbers
- Home or office addresses
- Birth dates
- Bank account details
- Corporate IDs not needed for the codebase
- Legal, finance, HR, or application paperwork
- Internal-only URLs, IDs, and operational notes
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.
