Note Improvement

Note Improvement

Capture improvement opportunities discovered during work so they don't get silently dropped. Appends to a project-level .turbo/improvements.md file that serves as a backlog of actionable ideas.

Step 1: Determine Project Root

Find the nearest .git directory or project root. The improvements file lives at .turbo/improvements.md relative to the project root.

Step 2: Identify the Improvement

Gather from context or $ARGUMENTS:

• What: One-line summary of the improvement
• Type: One of direct, investigate, or plan — see criteria below
• Category: One of refactor, performance, reliability, readability, testing, docs, dx (developer experience), or feature
• Where: File path(s) and/or area of the codebase affected
• Why: Brief rationale — what's the benefit?

Type criteria

• direct — Clear scope and a known approach, ready to apply via /implement.
• investigate — A symptom that needs root-cause analysis first: unclear root cause, performance question, intermittent bug, "something feels off".
• plan — Everything else: the approach warrants writing down before implementing (multi-file refactor, test additions, feature work).

When the criteria above clearly select one value, use it. Otherwise, use AskUserQuestion to confirm; default to plan if the user declines to choose.

Step 3: Append to File

Read .turbo/improvements.md if it exists. Create it with the header below if it doesn't.

File header (only when creating new):

# Improvements

Out-of-scope improvement opportunities captured during work sessions. Review periodically and pull items into active work when appropriate.

Entry format:

### <one-line summary>

- **Type**: <direct | investigate | plan>
- **Category**: <category>
- **Where**: `<file path or area>`
- **Why**: <brief rationale>
- **Noted**: <YYYY-MM-DD>

Append the new entry at the end of the file.

Step 4: Confirm

Tell the user the improvement was noted and where the file is.

Rules

• Deduplicate before appending: check for a similar entry and update it in place when one exists. When the existing entry predates the Type field, add a Type line while updating.
• When updating an existing entry tagged with the legacy values trivial or standard, rewrite the Type to direct or plan respectively so the file converges on current vocabulary.
• Keep entries concise — 3-5 lines max per entry. These are backlog items, not specs.
• Record only; leave action to the user, who decides when to address it.
• When the project has no .turbo/ directory, use AskUserQuestion to confirm the location before creating one.
