.claude/agents/provenance-reviewer.md

provenance-reviewer is an agent for Claude Code from Nosmoht/talos-mcp-server. It costs 43 tokens per session (1,112 once invoked), scanned A, original, MIT.

A read-only reviewer for the risks introduced by new or changed software dependencies. It examines where dependencies come from and whether they remain suitable to use.

In plain words
What is it for?
Reviewing go.mod and go.sum changes, including dependency licenses, maintenance activity, repository status, known vulnerabilities, and version constraints.
Why use it?
It helps identify licensing problems, abandoned packages, known security issues, weak version pinning, and other supply-chain concerns before release.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is Nosmoht/talos-mcp-server's own configuration. It tells Claude Code how to work on talos-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything talos-mcp-server configures →

Token cost

What it costs to keep this loaded

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.

Security

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.
