kastalien-research Distill wisdom from experience in this area: $ARGUMENTS
Process
1. Experience Inventory
Gather evidence of past decisions and outcomes:
- Read recent git history (
git log --oneline -20) - Review agent memory and learnings
- Check
.Codex/rules/for existing principles - Look at code patterns in the codebase
2. Pattern Extraction
For each significant decision or outcome:
- What was decided? (the choice made)
- What was the context? (constraints, information available)
- What happened? (outcome, downstream effects)
- Was it the right call? (with hindsight)
Look for:
- Success patterns — conditions that consistently lead to good outcomes
- Failure patterns — early warning signs of bad paths
- Evolution patterns — how thinking has changed over time
3. Principle Abstraction
Distill patterns into principles at the right abstraction level:
| Level | Example |
|---|---|
| Tactical | "Always run tests before committing database migrations" |
| Strategic | "Prefer reversible changes over irreversible ones" |
| Philosophical | "Optimize for time-to-signal, not time-to-completion" |
A good principle is:
- Actionable — you can act on it right now
- Falsifiable — you can identify situations where it doesn't apply
- Bounded — it states when it applies, not just what to do
4. Validation
Check each principle against past experience:
- Does it explain observed outcomes?
- Are there counter-examples?
- Under what conditions does it break?
5. Storage
Write validated principles to the appropriate location:
- Project-wide:
.Codex/rules/as a new or updated rule file - Agent-specific: Agent memory
- Session-specific:
MEMORY.md
Tag with freshness: HOT (just validated) | WARM (reasonable but not recently tested) | COLD (theoretical)
