learner

learner is a skill for Claude Code, Codex from naimkatiman/continuous-improvement. It costs 11 tokens per session (1,437 once invoked), scanned A, original, MIT.

A tool that extracts a reusable skill from the current conversation. A skill is a set of instructions that teaches an agent how to handle a recurring type of task.

In plain words
What is it for?
Use it to capture problem-solving principles and workflows as a new or improved agent skill.
Why use it?
It turns useful patterns discovered during a conversation into guidance that can be reused later.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

learner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Learner Skill

Deprecated compatibility alias: use /oh-my-claudecode:skillify for new skill extraction workflows. This file remains for internal implementation/history and compatibility.

This is a Level 7 (self-improving) skill. It has two distinct sections:

  • Expertise: Domain knowledge about what makes a good skill. Updated automatically as patterns are discovered.
  • Workflow: Stable extraction procedure. Rarely changes.

Only the Expertise section should be updated during improvement cycles.


Expertise

This section contains domain knowledge that improves over time. It can be updated by the learner itself when new patterns are discovered.

Core Principle

Reusable skills are not code snippets to copy-paste, but principles and decision-making heuristics that teach Claude HOW TO THINK about a class of problems.

The difference:

  • BAD (mimicking): "When you see ConnectionResetError, add this try/except block"
  • GOOD (reusable skill): "In async network code, any I/O operation can fail independently due to client/server lifecycle mismatches. The principle: wrap each I/O operation separately, because failure between operations is the common case, not the exception."

Quality Gate

Before extracting a skill, ALL three must be true:

  • "Could someone Google this in 5 minutes?" → NO
  • "Is this specific to THIS codebase?" → YES
  • "Did this take real debugging effort to discover?" → YES

Recognition Signals

Extract ONLY after:

  • Solving a tricky bug that required deep investigation
  • Discovering a non-obvious workaround specific to this codebase
  • Finding a hidden gotcha that wastes time when forgotten
  • Uncovering undocumented behavior that affects this project

What Makes a USEFUL Skill

  1. Non-Googleable: Something you couldn't easily find via search

    • BAD: "How to read files in TypeScript" ❌
    • GOOD: "This codebase uses custom path resolution in ESM that requires fileURLToPath + specific relative paths" ✓
  2. Context-Specific: References actual files, error messages, or patterns from THIS codebase

    • BAD: "Use try/catch for error handling" ❌
    • GOOD: "The aiohttp proxy in server.py:42 crashes on ClientDisconnectedError - wrap StreamResponse in try/except" ✓

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

learner is a skill published in the GitHub repository naimkatiman/continuous-improvement (7 stars, last pushed 10d ago), licensed MIT. It adds 11 tokens to every session and 1,437 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
