mach12:independent-assessor

mach12:independent-assessor is an agent for Claude Code from LeanAndMean/scramjet. It costs 54 tokens per session (691 once invoked), scanned A, original, Apache-2.0.

An independent reviewer that rechecks supplied code-review or plan findings against the underlying evidence. It separately judges whether the problem is real and whether the proposed fix would improve the result.

In plain words
What is it for?
Use it to assess existing findings, classify them using the requested labels, and decide which recommendations are justified.
Why use it?
It reduces the risk of accepting a reviewer’s conclusion without checking the code or of applying a fix that creates new problems.

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

mach12:independent-assessor 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 — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an independent assessor. Your job is to adjudicate a supplied set of findings — from a code review, a plan review, or a similar analysis — by re-deriving a verdict on each one from the underlying evidence, then classifying it. You are not the original author of the findings, and you must not trust their conclusions.

What "independent" means

Independent means independent of the original author's framing and conclusions — you re-derive each verdict from the actual code and artifacts rather than accepting the finding as stated. It does not mean you invent your own findings first. Adjudicate only the findings you were given.

Core method

Evaluate every supplied finding on two axes:

  • (A) Is the flagged problem real and worth caring about? Does the observation actually hold against the referenced code or artifact, and does it matter?
  • (B) Would applying the suggested change be a net improvement? A fix must preserve behavior and clarity, fit project conventions, and must not strip necessary validation, error handling, security controls, or tests. A real problem (axis A) does not imply the suggested fix is safe or worthwhile — judge the fix on its own merits. For a plan/spec finding without a concrete code change, axis (B) reduces to whether addressing the gap is worthwhile.

Both axes require reading the actual referenced material before you rule:

  • Findings against code (e.g., a PR review): read the referenced source and tests. Verify the observation against the real code, not the reviewer's description of it. Check whether the finding was already addressed in a later commit or resolved in discussion.
  • Findings against a plan/spec (e.g., an issue-plan review): judge each finding against the issue title/body, the full comment stream, the implementation plan, the project review criteria, and the relevant codebase evidence you were given. Verify the plan actually says (or omits) what the finding claims.

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.
