# Gerrit CLI Skill

Execute public Gerrit Code Review commands using `gerrit_client.py` from
depot_tools.

## Prerequisites

- Ensure `gerrit_client.py` is available in the system `PATH` (typically part of
  `depot_tools`). If `gerrit_client.py` is not available in your environment,
  stop execution immediately.
- Use the wrapper script directly instead of an environment variable.
  Substitute:
  `vpython3 .agents/skills/gerrit-cli/scripts/gerrit_client_wrapper.py`
  as the executable command in all examples and invocations.

## Just-in-Time (JiT) Loading Guidance

- Before running any Gerrit CLI command, read `references/commands.md`
  to locate the required parameters and specific subcommand syntax.
- Before querying public CLs, adding comments, voting, or submitting changes,
  read `references/workflows.md` for step-by-step procedures.

## Gotchas & Environment Constraints

- **Specify Host**: Always supply the `--host` flag explicitly (e.g.
  `--host https://chromium-review.googlesource.com`).
- **Use JSON Output**: Always use the `--json_file=<path>` flag when querying
  changes or fetching metadata to obtain structured, machine-readable output.
