commit.lint

Step 3/4 in full workflow

Full commit workflow: review, test, lint, and commit

Reviews code, runs tests, lints, and commits changes. Use when ready to commit work with quality checks.

Prerequisites (Verify First)

Before proceeding, confirm these steps are complete:

• /commit.test

Instructions

Goal: Formats and lints code with ruff using a sub-agent. Use after tests pass to ensure code style compliance.

Lint Code

Objective

Format and lint the codebase using ruff to ensure code quality and consistency.

Task

Run ruff format and ruff check to format and lint the code. This step should be executed using a sub-agent to conserve context in the main conversation.

Process

IMPORTANT: Use the Task tool to spawn a sub-agent for this work. This saves context in the main conversation. Use the haiku model for speed.

1. Spawn a sub-agent to run linting

   Use the Task tool with these parameters:

   • subagent_type: "Bash"
   • model: "haiku"
   • prompt: See below

   The sub-agent should:

   a. Run ruff format

   ruff format .
   

   This formats the code according to ruff's style rules.

   b. Run ruff check with auto-fix

   ruff check --fix .
   

   This checks for lint errors and automatically fixes what it can.

   c. Run ruff check again to verify

   ruff check .
   

   Capture the final output to verify no remaining issues.

2. Review sub-agent results

   • Check that both format and check completed successfully
   • Note any remaining lint issues that couldn't be auto-fixed

3. Handle remaining issues

   • If there are lint errors that couldn't be auto-fixed, fix them manually
   • Re-run ruff check to verify

Example Sub-Agent Prompt

Run ruff to format and lint the codebase:

1. Run: ruff format .
2. Run: ruff check --fix .
3. Run: ruff check . (to verify no remaining issues)

Report the results of each command.

Quality Criteria

• ruff format was run successfully
• ruff check was run with --fix flag
• No remaining lint errors (or all are documented and intentional)
• Sub-agent was used to conserve context
• When all criteria are met, include <promise>✓ Quality Criteria Met</promise> in your response

Context

This step ensures code quality and consistency before committing. It runs after tests pass and before the commit step. Using a sub-agent keeps the main conversation context clean for the commit review.

Job Context

A workflow for preparing and committing code changes with quality checks.

The full workflow starts with a code review to catch issues early, runs tests until they pass, formats and lints code with ruff, then reviews changed files before committing and pushing. The review and lint steps use sub-agents to reduce context usage.

Steps:

1. review - Code review for issues, DRY opportunities, naming, and test coverage (runs in sub-agent)
2. test - Pull latest code and run tests until they pass
3. lint - Format and lint code with ruff (runs in sub-agent)
4. commit_and_push - Review changes and commit/push

Work Branch

Use branch format: deepwork/commit-[instance]-YYYYMMDD

• If on a matching work branch: continue using it
• If on main/master: create new branch with git checkout -b deepwork/commit-[instance]-$(date +%Y%m%d)

Outputs

Required outputs:

• code_formatted

Guardrails

• Do NOT skip prerequisite verification if this step has dependencies
• Do NOT produce partial outputs; complete all required outputs before finishing
• Do NOT proceed without required inputs; ask the user if any are missing
• Do NOT modify files outside the scope of this step's defined outputs

On Completion

1. Verify outputs are created
2. Inform user: "full step 3/4 complete, outputs: code_formatted"
3. Continue workflow: Use Skill tool to invoke /commit.commit_and_push
