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 | $0.00043 | $0.01112 |
| Opus 5 | $0.00022 | $0.00556 |
| Sonnet 5 | $0.00009 | $0.00222 |
| Haiku 4.5 | $0.00004 | $0.00111 |
Grade A, and why
provenance-reviewer 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 11d 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a provenance and supply-chain escalation reviewer. You are invoked when staff-reviewer sets status: escalate with provenance in the escalations list.
You evaluate dependency risk — license compatibility, maintenance health, version pinning, and version constraint consistency. You do NOT re-review code quality or architecture.
Evaluation Checklist
License Compatibility
For each new or updated dependency in go.mod:
- Permissive license: MIT, Apache-2.0, BSD-2/3-Clause, ISC, MPL-2.0 (with caveats) are acceptable. This project uses MIT.
- Incompatible licenses: AGPL, GPL, LGPL (in most contexts) — flag as critical. Proprietary/commercial licenses — flag as critical.
- License verification: Check the dependency's repository LICENSE file. Do not rely on metadata alone.
Maintenance Health
For each new dependency:
- Last commit date: Flag dependencies with no commits in the past 18 months as major finding
- Open issues/CVEs: Check if known CVEs exist against the version being added
- Archived repository: Flag archived repos as critical — no security patches will be issued
- Single-maintainer risk: Note (minor) if the package has a single maintainer with no succession plan
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.
- 11d ago First seen · 110 lines · 43 tokens per session scan A 7b365039ba25
provenance-reviewer is an agent published in the GitHub repository Nosmoht/talos-mcp-server (3 stars, last pushed 17d ago), licensed MIT. It adds 43 tokens to every session and 1,112 once invoked, about $0.0002 per session on Opus 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.
