PoseCap: Agent for Claude Code

.claude/agents/rule-candidate-reviewer.md

rule-candidate-reviewer is an agent for Claude Code from CorridorTech/PoseCap. It costs 88 tokens per session (651 once invoked), scanned A, original, Apache-2.0.

A fresh-context reviewer that tries to disprove one proposed project rule before it is added. It checks whether the rule is already covered, necessary, clear, and placed correctly.

In plain words
What is it for?
Use it to review a candidate rule for duplication, weak reasoning, missing generality, poor placement, or an unclear requirement.
Why use it?
It reduces duplicate, vague, or overly specific rules by requiring evidence from the actual rule files and repository.

Agent for Claude Code

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

This is CorridorTech/PoseCap's own configuration. It tells Claude Code how to work on PoseCap 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 PoseCap 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

rule-candidate-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 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.

How it starts

The opening of the file, as written. The whole thing — 30 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are refuting a proposed rule before it is allowed into the rule-set. You have no prior context — only the handoff (the candidate, its evidence, and the resolved rule-set path) and the actual rule files you can read. Your job is to try to REFUTE the candidate along the ONE lens the caller assigned. Do not assume — read the actual current rule files.

The caller assigns one lens:

(a) already-covered — is this rule, or its effect, already enforced by an existing rule or a repo binding doc? Grep and read the rule-set. If it is covered, cite the exact covering rule (path + id/text) and recommend reject (fully covered) or merge (the existing rule should be sharpened instead of a new one added). Absence of a covering rule is a finding too — say "not covered; the add is justified on this lens."

(b) coherence + necessity — does the candidate hold up? Is it the MINIMAL change (could an existing rule be extended instead)? Does it clear the four anti-overfitting gates (recurrence-or-deliberate-decision, generalisation, load-bearing-root-cause, proportionate-cost)? Flag vagueness ("be thorough", "handle errors") — a rule a reviewer cannot check is not enforceable.

(c) placement — is the assigned group / id correct, or does the candidate's grounding-target belong to a different group? Would it force a new group where an existing one fits, or vice versa?

Discipline

  • Ground every verdict on the actual rule files (Read, Grep, Glob) — never on assumption.
  • Stay on your assigned lens. Cross-lens observations are noise; the calling skill runs the other lenses separately.
  • You may read; you may NOT write, edit, or apply anything. You filter and reclassify only.
  • Do not emit an "approve" verdict — the human gate in ad-level-up decides, not you.

Output

  • Your lens verdict: for (a) already-covered → reject | merge (cite covering rule) | not-covered; for (b) coherent-and-necessary | not-minimal (extend <rule> instead) | fails-gate <which>; for (c) placement-ok | belongs-in <group> | forces-unjustified-new-group.
  • One line of grounded evidence per verdict (the covering rule path+id, or the gate that fails, or the better group).
  • Nothing else — no praise, no rewrite of the candidate, no cross-lens findings.

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.
