dickwu Memory Save
Extract insights from the completed task and persist them to the knowledge system.
Steps
1. Reflect on the Task
Ask yourself:
- What did I learn about the codebase that wasn't already in knowledge.md?
- Did any hypothesis get confirmed or contradicted?
- Did I discover a new pattern that should be tracked?
- Did I make a mistake that revealed a rule worth recording?
2. Identify the Domain
Match insights to existing domain folders in knowledge/INDEX.md. If no folder fits, create a new domain folder with all three files (knowledge.md, hypotheses.md, rules.md) and add it to INDEX.md.
3. Categorize and Write
For each insight, decide where it goes:
knowledge.md — Confirmed facts and patterns
- **[topic]**: [fact] (observed [date])
hypotheses.md — Patterns that need more data
- **[topic]**: [hypothesis] (confirmations: N/5, first observed [date])
rules.md — Confirmed 5+ times, apply by default
- **[topic]**: [rule] (promoted [date], confirmed N times)
4. Promotion Check
Scan hypotheses.md in relevant domains. If any hypothesis now has 5+ confirmations:
- Remove it from hypotheses.md
- Add it to rules.md with
(promoted [today's date], confirmed N times) - Tell the user: "Promoted to rule: [hypothesis]"
5. Demotion Check
If today's work contradicted an existing rule in rules.md:
- Remove it from rules.md
- Add it back to hypotheses.md with
(demoted [today's date], contradicted by: [reason]) - Reset confirmation count to 0
- Tell the user: "Demoted rule: [rule] — contradicted by [reason]"
6. Update Hypothesis Counts
If today's work confirmed an existing hypothesis (but it's not yet at 5):
- Increment its confirmation count
- Tell the user: "Confirmed: [hypothesis] (now N/5)"
7. Summary
Report what was saved:
Saved to [domain]:
+ N new knowledge entries
+ N new hypotheses
^ N hypothesis confirmations
* N promotions to rules
v N demotions from rules
Ask Before Saving
Before writing, briefly list what you plan to save and ask: "Save these insights?" This gives the user a chance to add, remove, or correct entries before they're persisted.
Writing Good Entries
- Be specific and actionable — future sessions need to understand and apply these
- Include dates so staleness can be assessed
- One insight per bullet point
- Don't duplicate existing entries — update them instead
- Skip things derivable from reading the code — focus on non-obvious patterns and gotchas
