helix.mcp: Skill for Claude Code

.copilot/skills/reviewer-protocol/SKILL.md

reviewer-protocol is a skill for Claude Code, Codex from lewing/helix.mcp. It costs 13 tokens per session (988 once invoked), scanned A, a copy of reviewer-protocol, MIT.

A review workflow for teams where one agent checks another agent's work. If the reviewer rejects it, a different agent must revise it rather than the original author.

In plain words
What is it for?
Approving or rejecting work, assigning revisions to another agent, escalating work to a specialist, and enforcing the lockout after rejection.
Why use it?
It preserves independent review and prevents the person who made the work from immediately judging and correcting their own rejected version.

Written for no agent in particular: nothing here depends on one.

This is lewing/helix.mcp's own configuration. It tells Claude Code and Codex how to work on helix.mcp 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 helix.mcp 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

reviewer-protocol 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 8d 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.

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

When a team member has a Reviewer role (e.g., Tester, Code Reviewer, Lead), they may approve or reject work from other agents. On rejection, the coordinator enforces strict lockout rules to ensure the original author does NOT self-revise. This prevents defensive feedback loops and ensures independent review.

Patterns

Reviewer Rejection Protocol

When a team member has a Reviewer role:

  • Reviewers may approve or reject work from other agents.
  • On rejection, the Reviewer may choose ONE of:
    1. Reassign: Require a different agent to do the revision (not the original author).
    2. Escalate: Require a new agent be spawned with specific expertise.
  • The Coordinator MUST enforce this. If the Reviewer says "someone else should fix this," the original agent does NOT get to self-revise.
  • If the Reviewer approves, work proceeds normally.

Strict Lockout Semantics

When an artifact is rejected by a Reviewer:

  1. The original author is locked out. They may NOT produce the next version of that artifact. No exceptions.
  2. A different agent MUST own the revision. The Coordinator selects the revision author based on the Reviewer's recommendation (reassign or escalate).
  3. The Coordinator enforces this mechanically. Before spawning a revision agent, the Coordinator MUST verify that the selected agent is NOT the original author. If the Reviewer names the original author as the fix agent, the Coordinator MUST refuse and ask the Reviewer to name a different agent.
  4. The locked-out author may NOT contribute to the revision in any form — not as a co-author, advisor, or pair. The revision must be independently produced.
  5. Lockout scope: The lockout applies to the specific artifact that was rejected. The original author may still work on other unrelated artifacts.
  6. Lockout duration: The lockout persists for that revision cycle. If the revision is also rejected, the same rule applies again — the revision author is now also locked out, and a third agent must revise.
  7. Deadlock handling: If all eligible agents have been locked out of an artifact, the Coordinator MUST escalate to the user rather than re-admitting a locked-out author.

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.
