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 | $0.01582 | $0.01582 |
| Opus 5.5 | $0.00633 | $0.00633 |
| Sonnet 5.5 | $0.00316 | $0.00316 |
| Haiku 4.5 | $0.00158 | $0.00158 |
Grade A, and why
enferno 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 23d 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

enferno/app.py - Database: SQLAlchemy 2.x (
db.select(),db.paginate()), Alembic via Flask-Migrate. SQLite by default, PostgreSQL throughpsycopg3 - Auth: Flask-Security-Too 5.9 (email login, TOTP 2FA, WebAuthn, recovery codes), Google/GitHub OAuth via Flask-Dance
- Frontend: Vue 3 + Vuetify 4 served from
enferno/static/js/, no build step, Tabler icons vendored inenferno/static/tabler/ - Optional: Redis sessions and Celery (
uv sync --extra full); MCP server for agents (--extra mcp); uWSGI (--extra wsgi) - Tooling:

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.
