gerrit-create

A procedure for sending code changes to Gerrit, a code-review system, and updating the review afterward. It covers the special review branch, required change identifier, commit structure, target branch, and reviewer metadata.

In plain words
What is it for?
Use it to create or update a Gerrit review, push a patch set, add reviewers or watchers, group changes by topic, or mark work as unfinished.
Why use it?
Gerrit expects changes in a particular format, and each pushed commit can become a separate review. This guide helps prepare and upload a change that reviewers can process correctly.

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

gerrit-create 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.

Creating and Updating Gerrit Changes

Guide for pushing code changes to Gerrit for review.

Prerequisites

The Gerrit MCP server must be available and git must be configured with the appropriate remote.

Creating a new change

Gerrit changes are created by pushing commits to a special ref:

git push origin HEAD:refs/for/<target-branch>

Before pushing

  1. Commit message format: Gerrit requires a Change-Id footer in the commit message. If the Gerrit commit-msg hook is installed, it adds this automatically. If not:

    Subject line (50 chars max)
    
    Body explaining what and why (wrapped at 72 chars).
    
    Change-Id: I<40-char-hex>
    
  2. Single commit per change: Each commit becomes one Gerrit change. Squash work-in-progress commits before pushing.

  3. Target branch: Usually main or master, but verify the project's default branch.

Push options

Add metadata via push options:

git push origin HEAD:refs/for/main \
  -o topic=my-feature \
  -o [email protected] \
  -o [email protected] \
  -o wip
  • topic=<name> — group related changes
  • r=<email> — add reviewer
  • cc=<email> — add CC
  • wip — mark as work-in-progress
  • ready — mark as ready for review
  • hashtag=<tag> — add hashtag

Updating an existing change

To upload a new patch set for an existing change:

  1. Amend the commit (keep the same Change-Id):

    git commit --amend
    
  2. Push again:

    git push origin HEAD:refs/for/main
    

Gerrit matches the Change-Id to the existing change and creates a new patch set.

Managing change metadata

After a change exists, use mcp__gerrit__submit_gerrit_review to:

  • Add comments explaining what changed in the new patch set
  • Vote on your own change (if allowed by project settings)
  • Reply to reviewer comments

Use mcp__gerrit__fetch_gerrit_change to verify the change was created/updated correctly.

Common issues

  • Missing Change-Id: Install the commit-msg hook: gitdir=$(git rev-parse --git-dir); scp -p -P 29418 <user>@<host>:hooks/commit-msg ${gitdir}/hooks/
  • Push rejected (not permitted): Check project permissions and target branch
  • Merge conflict on push: Rebase on the target branch first
  • Change already merged: The Change-Id was reused — create a new commit with a fresh Change-Id

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.
