self-learning-skills

A self-improving skill for AI coding agents. Works with Claude Code, Cursor, and any agent that reads an AGENTS.md / standing-instructions file.

Every session you do hard debugging or rediscover the same thing — how do I reach the prod DB? where do the creds live? what's the deploy command? how do I verify this live? — and that hard-won knowledge evaporates when the session ends. The next session starts from zero and re-learns it.

self-learning fixes that. It teaches your agent to recognize the moment it has just earned a reusable golden path and persist it where the tool will auto-load it next time — so the next session starts already knowing the route instead of rediscovering it.

It's a meta-skill: it doesn't do the work, it captures how the work got done — including the failures, since skipping a known dead-end next session is often worth more than the win itself.

1. Recognize the moment — a task that only worked after several tries, a non-obvious command, a project fact you didn't know up front, an operational workflow likely to recur, or you simply saying "remember this".
2. Capture it, no prompt needed — it acts on the cue immediately, picks the scope/name itself, and tells you afterward. The procedure is captured (not a one-off answer), plus a "what didn't work" note.
3. Reuse — next session the entry loads automatically, by skill/rule description or because the instructions file is always read.

What differs per tool is only where knowledge is persisted and how it's auto-loaded:

Uses the community skills CLI, which installs into whatever agents it detects — Claude Code, Cursor, Codex, Cline, OpenCode, and more:

npx skills add kulaxyz/self-learning-skills                 # this project (auto-detects agents)
npx skills add kulaxyz/self-learning-skills -g              # global — all your projects
npx skills add kulaxyz/self-learning-skills -a claude-code  # a specific agent

Try it once without installing:

npx skills use kulaxyz/self-learning-skills --skill self-learning | claude

/plugin marketplace add kulaxyz/self-learning-skills
/plugin install self-learning@self-learning-skills

git clone https://github.com/kulaxyz/self-learning-skills

# Claude Code — global (or into a project's .claude/skills/ to share via git)
cp -R self-learning-skills/skills/self-learning ~/.claude/skills/

# Cursor — auto-loads .cursor/rules/ (harvested rules land in .cursor/rules/learned/)
mkdir -p .cursor/rules
cp self-learning-skills/.cursor/rules/self-learning.mdc .cursor/rules/

# Any AGENTS.md agent (Codex, Zed, Aider, Gemini CLI, …)
curl https://raw.githubusercontent.com/kulaxyz/self-learning-skills/main/AGENTS.md >> AGENTS.md

It won't bloat your config with one-liners. Each lesson is routed:

Triage decides granularity; the promotion rule decides confidence. A skill is authoritative — the next session trusts it without re-deriving it — so a session is only promoted to a skill when all three hold:

1. A passing check — the path was actually verified (a test passed, a clean exit, a green build, a reproduced repro). "Seemed to work" doesn't count.
2. A named failure pattern — the failure it avoids or diagnoses, named.
3. At least one ruled-out dead-end — a concrete approach tried and eliminated.

Miss any one and it stays a tentative memory note (or is skipped) rather than a skill. This keeps confident-but-unverified guesses out of the skill set. (Promotion rule suggested by community feedback.)

Harvested skills/rules get committed and shared, so this is built to never write secret values — no passwords, tokens, connection strings, or API keys. It records only where to find a secret (env var name, a client/selector function, an MCP tool, a secret manager). Reproducing a secret into a shared file leaks it.
