Captures learnings, errors, corrections, and feature requests to enable continuous improvement. Use when: (1) User corrects Claude ('No, that's wrong...', 'Actually...'), (2) User requests a capability that doesn't exist, (3) Claude realizes its knowledge is outdated or incorrect, (4) A better approach is discovered for a recurring task, (5) Receiving a Handoff block from self-healing (a recurring verified heal at Recurrence-Count >= 3) to distill into a memory file or new skill. For ACTIVE runtime failures where the agent needs to apply and verify a fix mid-task, use `self-healing` instead (it files HEAL- entries with proof; self-improvement promotes accumulated patterns). Also review learnings before major tasks. For CI-only/headless learning capture, use self-improvement-ci.

Fix and improve this skill with Tessl
tessl review fix ./skills/self-improvement/SKILL.mdgh skill install pskoett/pskoett-skills self-improvementFor CI-only execution, use:
gh skill install pskoett/pskoett-skills self-improvement-ciFallback using the Agent Skills CLI:
npx skills add pskoett/pskoett-skills/skills/self-improvement
npx skills add pskoett/pskoett-skills/skills/self-improvement-ciLog 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.
Pair with self-healing: self-healing is the active runtime recovery primitive — it diagnoses, patches, verifies, and files HEAL- entries to .learnings/HEALS.md when something breaks mid-task. Self-improvement (this skill) is the passive accumulation and promotion layer — it logs corrections, knowledge gaps, and feature requests, and promotes recurring heal handoffs to permanent memory. They share .learnings/ but write to different files; verify discipline lives in self-healing, promotion logic lives here.

Write promoted rules as short prevention rules (what to do before/while coding), not long incident write-ups.

Knowledge Gaps (→ learning with knowledge_gap category):
Errors (→ error entry):

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/.gitkeepEnable automatic reminders through agent hooks. This is opt-in - you must explicitly configure hooks. The same two scripts work across Claude Code and Codex CLI (both deliver JSON on stdin and accept the same additionalContext output shape); Copilot hooks can log but not inject context, so Copilot uses the instructions-file channel. Full per-agent setup including Codex and Copilot: references/hooks-setup.md.
Create .claude/settings.json in your project. The command path must point to where the skill is actually installed: .claude/skills/self-improvement/ for gh skill install / npx skills add, or skills/self-improvement/ if this repo is vendored into the project. Relative paths resolve from the project root.
{
"hooks": {
"UserPromptSubmit": [{
"hooks": [{
"type": "command",
"command": "${CLAUDE_PROJECT_DIR}/.claude/skills/self-improvement/scripts/activator.sh"
}]
}]
}
}This injects a learning evaluation reminder after each prompt (~50-100 tokens overhead).
{
"hooks": {
"UserPromptSubmit": [{
"hooks": [{
"type": "command",
"command": "${CLAUDE_PROJECT_DIR}/.claude/skills/self-improvement/scripts/activator.sh"

"matcher": "Bash",
"hooks": [{
"type": "command",
"command": "${CLAUDE_PROJECT_DIR}/.claude/skills/self-improvement/scripts/error-detector.sh"
}]
}]
}
}Hooks receive the event payload as JSON on stdin. The error detector parses tool_response from that JSON and returns its reminder as additionalContext JSON output, which is required for PostToolUse output to reach the model.
| Script | Hook Type | Purpose |
|---|---|---|
scripts/activator.sh | UserPromptSubmit (Claude Code, Codex) | Reminds to evaluate learnings after tasks (plain stdout is added to context for this event on both agents) |
scripts/error-detector.sh | PostToolUse (Claude Code, Codex), postToolUse (Copilot, logging only) | Parses the stdin JSON payload for error patterns across all three agents' payload shapes; emits an additionalContext reminder |

When a learning is valuable enough to become a reusable skill, extract it using the provided helper.
A learning qualifies for skill extraction when ANY of these apply:
| Criterion | Description |
|---|---|
| Recurring | Has See Also links to 2+ similar issues |
| Verified | Status is resolved with working fix |
| Non-obvious | Required actual debugging/investigation to discover |
| Broadly applicable | Not project-specific; useful across codebases |
| User-flagged | User says "save this as a skill" or similar |

This skill works across different AI coding agents with agent-specific activation.
Activation: Hooks (UserPromptSubmit, PostToolUse)
Setup: .claude/settings.json with hook configuration
Detection: Automatic via hook scripts
Activation: Hooks (UserPromptSubmit, PostToolUse) — experimental, behind codex_hooks = true in config.toml
Setup: <repo>/.codex/hooks.json or ~/.codex/hooks.json; same scripts, same payload/output shapes as Claude Code
Detection: Automatic via hook scripts; see references/hooks-setup.md for the config
Fallback: Add the self-improvement guidance to AGENTS.md if hooks are unavailable
Activation: Instructions file (Copilot hooks exist in .github/hooks/*.json but their output is ignored for prompt/tool events — they can log, not inject context)
Setup: Add to .github/copilot-instructions.md:
## Self-Improvement
After solving non-obvious issues, consider logging to `.learnings/`:
1. Use format from self-improvement skill
2. Link related entries with See Also
3. Promote high-value learnings to skills
Ask in chat: "Should I log this as a learning?"Detection: Manual review at session end
OpenClaw-specific setup, promotion targets, and hybrid usage details are kept in
references/openclaw-integration.md so this main skill stays focused on the core
self-improvement workflow for coding agents.
Regardless of agent, apply self-improvement when you:
For Copilot users, add this to your prompts when relevant:
After completing this task, evaluate if any learnings should be logged to
.learnings/using the self-improvement skill format.
Or use quick prompts:

If you maintain this skill, you can claim it as your own. Once claimed, you can manage eval scenarios, bundle related skills, attach documentation or rules, and ensure cross-agent compatibility.
