description: "Capture a reusable learning from completed work so future similar work is easier. Use when the user says 'save this learning', 'capture this insight', or finishes something tricky. Also use proactively after non-routine work. Not for recording a *decision* and its rationale; use `decision-log`."

Capture what you learned from completing work. This is the "compound" step—making future similar work easier.

Arguments

$WORK_COMPLETED: What did you just complete? (project milestone, tricky problem, meeting, workflow improvement, etc.)

Process

1. Reflection Questions

Ask the user (or extract from recent work context):

1. **What was the situation?**

  • Original goal or challenge
  • Why it was harder than expected (if applicable)

2. **What approach worked?**

  • Strategy or tactic used
  • Key decisions made

3. **What would you do differently?**

  • Gotchas encountered
  • Better approaches discovered late

4. **What's reusable?**

  • Patterns that apply elsewhere
  • Mental models that help

2. Create or Update Learning Note

Store in: `06-Resources/Learnings/[Category]_Learnings.md`

**Categories:**

  • `Working_Preferences` - How you like to work, communication style, tool preferences
  • `Mistake_Patterns` - Common errors to avoid, with triggers and corrections

Create new category files as needed for domain-specific learnings.

3. Learning Entry Format

Append to the appropriate file:

---

## [Short Title] — [Date]

**Context:** [1 sentence on what you were doing]

**Challenge:** [What was tricky or non-obvious]

**What Worked:** 
[The approach that succeeded]

**Key Insight:** 
> [The memorable takeaway—something you'd tell past-you]

**See Also:** [Related notes if any]

4. Cross-Link (Optional)

If the learning relates to:

  • A person → Add to their person page
  • A project → Add link in project's note
  • A recurring workflow → Update relevant template

Output

1. Ask reflection questions (or extract from context) 2. Create/update the appropriate learning file 3. Suggest any cross-links 4. Confirm saved

Philosophy

> "The palest ink is better than the best memory." — Chinese proverb

This isn't documentation for others—it's a gift to future-you. Be specific. Include the gotcha. Make it searchable.

Track Usage (Silent)

Call the `mark_feature_used` tool on the `dex-analytics` MCP server with `save-insight`. This ticks the feature's box in `System/usage_log.md`, which is what `/dex-level-up` reads to recommend features that have not been tried. It writes locally and sends nothing, so it runs whether or not analytics is enabled.

**Analytics (Silent):**

Call `track_event` with event_name `insight_saved` and properties:

  • category

This only fires if the user has opted into analytics. No action needed if it returns "analytics_disabled".
