Self-Improvement Skill
Log learnings and errors to markdown files for continuous improvement. Coding agents can later process these into fixes, and important learnings get promoted to project memory.
Quick Reference
| Situation | Action |
|---|---|
| Command/operation fails | Log to .learnings/ERRORS.md |
| User corrects you | Log to .learnings/LEARNINGS.md with category correction |
| User wants missing feature | Log to .learnings/FEATURE_REQUESTS.md |
| API/external tool fails | Log to .learnings/ERRORS.md with integration details |
| Knowledge was outdated | Log to .learnings/LEARNINGS.md with category knowledge_gap |
| Found better approach | Log to .learnings/LEARNINGS.md with category best_practice |
| Similar to existing entry | Link with **See Also**, consider priority bump |
| Broadly applicable learning | Promote to CLAUDE.md and/or AGENTS.md |
Setup
Create .learnings/ directory in project root if it doesn't exist:
mkdir -p .learnings
Copy templates from assets/ or create files with headers.
Logging Format
Learning Entry
Append to .learnings/LEARNINGS.md:

---
ID Generation
Format: TYPE-YYYYMMDD-XXX
- TYPE:
LRN(learning),ERR(error),FEAT(feature) - YYYYMMDD: Current date
- XXX: Sequential number or random 3 chars (e.g.,
001,A7B)
Examples: LRN-20250115-001, ERR-20250115-A3F, FEAT-20250115-002
Resolving Entries
When an issue is fixed, update the entry:
- Change
**Status**: pending→**Status**: resolved - Add resolution block after Metadata:
### Resolution
- **Resolved**: 2025-01-16T09:00:00Z
- **Commit/PR**: abc123 or #42
- **Notes**: Brief description of what was done
Other status values:
in_progress- Actively being worked onwont_fix- Decided not to address (add reason in Resolution notes)promoted- Elevated to CLAUDE.md or AGENTS.md
Promoting to Project Memory
When a learning is broadly applicable (not a one-off fix), promote it to permanent project memory.
When to Promote
- Learning applies across multiple files/features
- Knowledge any contributor (human or AI) should know
- Prevents recurring mistakes
- Documents project-specific conventions
Promotion Targets
| Target | What Belongs There |
|---|---|
CLAUDE.md |
Project facts, conventions, gotchas for all Claude interactions |
AGENTS.md |
Agent-specific workflows, tool usage patterns, automation rules |
How to Promote
- Distill the learning into a concise rule or fact
- Add to appropriate section in target file
- Update original entry:
- Change
**Status**: pending→**Status**: promoted - Add
**Promoted**: CLAUDE.mdor**Promoted**: AGENTS.md
- Change
Promotion Examples
Learning (verbose):
Project uses pnpm workspaces. Attempted
npm installbut failed. Lock file ispnpm-lock.yaml. Must usepnpm install.
In CLAUDE.md (concise):
## Build & Dependencies
- Package manager: pnpm (not npm) - use `pnpm install`
Learning (verbose):
When modifying API endpoints, must regenerate TypeScript client. Forgetting this causes type mismatches at runtime.
In AGENTS.md (actionable):
## After API Changes
1. Regenerate client: `pnpm run generate:api`
2. Check for type errors: `pnpm tsc --noEmit`
Recurring Pattern Detection
If logging something similar to an existing entry:
- Search first:
grep -r "keyword" .learnings/ - Link entries: Add
**See Also**: ERR-20250110-001in Metadata - Bump priority if issue keeps recurring
- Consider systemic fix: Recurring issues often indicate:
- Missing documentation (→ promote to CLAUDE.md)
- Missing automation (→ add to AGENTS.md)
- Architectural problem (→ create tech debt ticket)
Periodic Review
Review .learnings/ at natural breakpoints:
When to Review
- Before starting a new major task
- After completing a feature
- When working in an area with past learnings
- Weekly during active development
Quick Status Check
# Count pending items
grep -h "Status\*\*: pending" .learnings/*.md | wc -l
# List pending high-priority items
grep -B5 "Priority\*\*: high" .learnings/*.md | grep "^## \["
# Find learnings for a specific area
grep -l "Area\*\*: backend" .learnings/*.md
Review Actions
- Resolve fixed items
- Promote applicable learnings
- Link related entries
- Escalate recurring issues
Detection Triggers
Automatically log when you notice:
Corrections (→ learning with correction category):
- "No, that's not right..."
- "Actually, it should be..."
- "You're wrong about..."
- "That's outdated..."
Feature Requests (→ feature request):
- "Can you also..."
- "I wish you could..."
- "Is there a way to..."
- "Why can't you..."
Knowledge Gaps (→ learning with knowledge_gap category):
- User provides information you didn't know
- Documentation you referenced is outdated
- API behavior differs from your understanding
Errors (→ error entry):
- Command returns non-zero exit code
- Exception or stack trace
- Unexpected output or behavior
- Timeout or connection failure
Priority Guidelines
| Priority | When to Use |
|---|---|
critical |
Blocks core functionality, data loss risk, security issue |
high |
Significant impact, affects common workflows, recurring issue |
medium |
Moderate impact, workaround exists |
low |
Minor inconvenience, edge case, nice-to-have |
Area Tags
Use to filter learnings by codebase region:
| Area | Scope |
|---|---|
frontend |
UI, components, client-side code |
backend |
API, services, server-side code |
infra |
CI/CD, deployment, Docker, cloud |
tests |
Test files, testing utilities, coverage |
docs |
Documentation, comments, READMEs |
config |
Configuration files, environment, settings |
Best Practices
- Log immediately - context is freshest right after the issue
- Be specific - future agents need to understand quickly
- Include reproduction steps - especially for errors
- Link related files - makes fixes easier
- Suggest concrete fixes - not just "investigate"
- Use consistent categories - enables filtering
- Promote aggressively - if in doubt, add to CLAUDE.md
- Review regularly - stale learnings lose value
Gitignore Options
Keep learnings local (per-developer):
.learnings/
Track learnings in repo (team-wide): Don't add to .gitignore - learnings become shared knowledge.
Hybrid (track templates, ignore entries):
.learnings/*.md
!.learnings/.gitkeep
