learn-eval

A command for finding reusable lessons in a work session, checking their quality, and deciding whether to save them globally or in the current project.

In plain words
What is it for?
Use it to capture debugging methods, fixes, workarounds, and project patterns as reusable skill files.
Why use it?
It reduces the chance of saving vague or misplaced notes as future instructions.

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

learn-eval 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 2d ago.

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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/learn-eval - Extract, Evaluate, then Save

Extends /learn with a quality gate, save-location decision, and knowledge-placement awareness before writing any skill file.

What to Extract

Look for:

  1. Error Resolution Patterns — root cause + fix + reusability
  2. Debugging Techniques — non-obvious steps, tool combinations
  3. Workarounds — library quirks, API limitations, version-specific fixes
  4. Project-Specific Patterns — conventions, architecture decisions, integration patterns

Process

  1. Review the session for extractable patterns

  2. Identify the most valuable/reusable insight

  3. Determine save location:

    • Ask: "Would this pattern be useful in a different project?"
    • Global (~/.claude/skills/learned/): Generic patterns usable across 2+ projects (bash compatibility, LLM API behavior, debugging techniques, etc.)
    • Project (.claude/skills/learned/ in current project): Project-specific knowledge (quirks of a particular config file, project-specific architecture decisions, etc.)
    • When in doubt, choose Global (moving Global → Project is easier than the reverse)
  4. Draft the skill file using this format:

---
name: pattern-name
description: "Under 130 characters"
user-invocable: false
origin: auto-extracted
---

# [Descriptive Pattern Name]

**Extracted:** [Date]
**Context:** [Brief description of when this applies]

## Problem
[What problem this solves - be specific]

## Solution
[The pattern/technique/workaround - with code examples]

## When to Use
[Trigger conditions]
  1. Quality gate — Checklist + Holistic verdict

    5a. Required checklist (verify by actually reading files)

    Execute all of the following before evaluating the draft:

    • Grep ~/.claude/skills/ and relevant project .claude/skills/ files by keyword to check for content overlap
    • Check MEMORY.md (both project and global) for overlap
    • Consider whether appending to an existing skill would suffice
    • Confirm this is a reusable pattern, not a one-off fix

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.

learn-eval is a command published in the GitHub repository naimkatiman/continuous-improvement (7 stars, last pushed 7d ago), licensed MIT. It adds 29 tokens to every session and 1,196 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 2026-08-31.
