Run Warden to analyze code changes before committing. Use when asked to "run warden", "check my changes", "review before commit", "warden config", "warden.toml", "create a warden skill", "add trigger", or any Warden-related local development task.

🧰 Not standalone. This skill ships with getsentry/xcodebuildmcp and only works together with that tool — install the tool first, then add this skill.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

Run Warden to analyze code changes before committing.

Pre-Commit Workflow

After making code changes and before committing:

Run warden to analyze uncommitted changes
Review the findings
Fix issues Warden reports (or use warden --fix to auto-apply)
Commit the changes

Run Warden once to validate work. Do not loop re-running Warden on the same changes.

Reading Output

Severity levels:

high - Must fix before merge
medium - Worth reviewing
low - Minor improvement

Exit codes: 0 = no findings at or above fail threshold. 1 = findings at or above fail threshold.

Verbosity: -v shows real-time findings. -vv shows debug info (tokens, latency). -q shows errors and summary only.

`warden init`	Initialize warden.toml and GitHub workflow
