code-apply-hermit

A command that passes findings from the latest code review to Hermit, an automated code-editing system.

In plain words
What is it for?
Use it with a pull-request number and optional severity filters to apply P1–P5 review findings in the relevant worktree.
Why use it?
It lets the review findings guide mechanical edits without rereading every file and manually repeating each change.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

code-apply-hermit 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 2d 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 — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/code-apply-hermit — Claude reads the review, Hermit applies it

Hands the P1–P5 findings from the most recent /code-review to Hermit so Claude doesn't burn tokens re-reading every file and retyping every edit. Claude stays on judgment; Hermit does the mechanical apply.

Arguments

$ARGUMENTS — PR number, optionally followed by severity filters. Examples: 123, 123 P1 P2 P3.

  • --model <model_name> — which executor model Hermit should run. Defaults to the gateway's active model (./bin/gateway.sh --status to see the current pick).

Prerequisites

  • A /code-review output from the previous turn in this conversation.
  • Hermit gateway + MCP server running.

Workflow

Step 1 — locate the worktree

If the argument contains a PR number, follow the repo's worktree convention to resolve the worktree path (or infer from the current branch if you are already inside it). If no worktree / PR info can be resolved, ask the user which directory to operate on.

Step 2 — harvest review findings

Scan the prior conversation for the last /code-review output and extract each finding: severity, file path, line number, description, and the proposed direction.

If no review output is present, stop and tell the user to run /code-review $ARGUMENTS first.

Step 3 — choose what to apply

  • Default: every P1 through P5 item.
  • Filter: if severities are listed in $ARGUMENTS (e.g. P1 P2), apply only those.

Step 3.5 — write findings to disk

Save the selected findings to:

.omc/reviews/<branch>-review-<YYYYMMDDHHMMSS>.md

Format:

# Code Review Findings — <branch>

## P1
- `path/to/file.py:42` — short description — suggested fix

## P2
- ...

Step 4 — concurrency lock

mkdir -p .hermit
cat > .hermit/active-task.lock <<EOF
{
  "task_id": "<filled-after-run_task>",

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.
