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 | $0.00216 | $0.00216 |
| Opus 5.5 | $0.00086 | $0.00086 |
| Sonnet 5.5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
tero-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 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.

What it actually says
AGENTS.md — tero-mcp (Python lite + packaging)
Tero-first: use tero MCP or scripts/tero.sh before changes.
Hygiene
Use scripts/check.sh (or equiv uv/pytest/ruff).
Secrets, .env and git-secrets protection (2026-07-10, tooling 1.0 wave)
WHAT:
- Added .env* rules to .gitignore.
- git-secrets hooks installed, patterns for XAI_API_KEY + others registered, .gitallowed for safe doc mentions, scan verified clean. WHY: Workspace tooling (incl. cabal-devmelopner using XAI key) requires protection. 1.0 hardening. Re-setup:
git secrets --install
git secrets --register-aws
git secrets --add 'XAI_API_KEY'
git secrets --scan
Cites: tooling 1.0 wave doc + this task. Append-only.
Follow guards, use worktrees for parallel, update tero index after docs.
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.
