Decision Extractor

Scan recent notes (weekly reports, meetings) for decision language and surface decisions that should be logged in project files.

Arguments

• Time range (optional): "this week", "last 2 weeks", "this month" (default: last 2 weeks)
• Project filter (optional): Only look for decisions about a specific project
• --include-slack: Also scan Slack for decision language (default: vault only)

Steps

1. Find files to scan:

   • Glob recent weekly reports based on time range
   • Glob meeting notes in those week folders
   • If project filter, narrow scope

2. Scan vault for decision language: Pattern match for phrases indicating decisions:

   • "decided to", "decision:", "the call is"
   • "agreed on", "agreed to", "we'll go with"
   • "chose to", "choosing", "selected"
   • "approved", "signed off on"
   • "not doing", "won't pursue", "deprioritizing"
   • "the plan is", "moving forward with"
   • "resolved to", "committed to"

3. Scan Slack for decisions (if --include-slack):

   • Use mcp__playground-slack-mcp__get_messages with action: my_messages
   • Time range: Match the vault time range argument
   • Search sent messages and @mentions for same decision patterns
   • These are "async decisions" that may not have made it to vault notes
   • Skip gracefully if Slack MCP unavailable

4. Extract decision context:

   • The decision itself
   • Date (from file or section)
   • People involved (if mentioned)
   • Project/topic it relates to
   • Rationale (if stated)
   • Source: vault file or Slack (channel + thread link)

5. Match to projects:

   • For each decision, identify which project it relates to
   • Check if project has a Decision Log section
   • Check if decision is already logged

6. Present findings:

   • Show decisions found
   • Indicate which are already logged vs. new
   • Group by project
   • Mark Slack decisions with source channel

7. Offer to update:

   • For new decisions, ask if user wants to add to Decision Log
   • If confirmed, use Edit tool to append to project file

Output Format

## Decisions Found ([time range])

### [[project-1]]

**Already Logged:**
- [Date]: [Decision] ?

**New (not in Decision Log):**
- [Date]: [Decision]
  - Source: `meeting-2025-01-06-person.md`
  - Context: [brief rationale if found]
  - -> Add to Decision Log? [Y/N]

### [[project-2]]

**New:**
- [Date]: [Decision]
  - Source: `weekly-report-w02.md`
  - -> Add to Decision Log? [Y/N]

### Unmatched (no clear project)

- [Date]: [Decision]
  - Source: [file]
  - Possible projects: [[project-a]], [[project-b]]

### From Slack (--include-slack)

- [Date]: [Decision]
  - Source: #[channel] ([thread link])
  - Participants: @person1, @person2
  - -> Add to Decision Log? [Y/N]

Decision Log Format

When adding to project files, use this table format:

## Decision Log

| Date | Decision | Context |
|------|----------|---------|
| 2025-01-06 | Chose Figma over Sketch for prototypes | Team familiarity, better collaboration |
| 2025-01-08 | Scoped out mobile for v1 | #proj-channel (Slack) |

For Slack decisions, include channel name as context. Link to thread if available.

Notes

• Don't add duplicates. Check existing Decision Log first.
• If a project doesn't have a Decision Log section, offer to create one
• For decisions that span multiple projects, log in the primary project and note the connection
• "Context" should be brief (one sentence). Link to source file for details.
• Ask before writing. This skill modifies files.
• Some "decisions" are actually action items. Use judgment. Decisions are choices between options; actions are tasks to do.
