learn

learn is a command for coding agents from affaan-m/ECC. It costs 8 tokens per session (324 once invoked), scanned A, original, MIT.

A command that reviews the current conversation and code changes to record reusable patterns, good practices, mistakes, and code examples.

In plain words
What is it for?
It extracts discoveries and suggests updates to coding skills or rules, including structured instincts with triggers and confidence levels.
Why use it?
It helps preserve useful lessons from one coding session so they can guide later work.

About the project

ECC is a toolkit that organizes and improves how coding agents work through skills, memory, security checks, research practices, and related extensions. It is for developers using agents such as Claude Code, Codex, OpenCode, and Cursor.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo
git clone --depth 1 https://github.com/affaan-m/ECC

Or install ecc, the plugin that ships this one along with the rest of its 70 skills, 56 commands, 68 agents, 1 MCP server.

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 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.

What it actually says

Learn Command

Extract patterns, learnings, and reusable insights from the current session: $ARGUMENTS

Your Task

Analyze the conversation and code changes to extract:

  1. Patterns discovered - Recurring solutions or approaches
  2. Best practices applied - Techniques that worked well
  3. Mistakes to avoid - Issues encountered and solutions
  4. Reusable snippets - Code patterns worth saving

Output Format

Patterns Discovered

Pattern: [Name]

  • Context: When to use this pattern
  • Implementation: How to apply it
  • Example: Code snippet

Best Practices Applied

  1. [Practice name]
    • Why it works
    • When to apply

Mistakes to Avoid

  1. [Mistake description]
    • What went wrong
    • How to prevent it

Suggested Skill Updates

If patterns are significant, suggest updates to:

  • skills/coding-standards/SKILL.md
  • skills/[domain]/SKILL.md
  • rules/[category].md

Instinct Format (for continuous-learning-v2)

{
  "trigger": "[situation that triggers this learning]",
  "action": "[what to do]",
  "confidence": 0.7,
  "source": "session-extraction",
  "timestamp": "[ISO timestamp]"
}

TIP: Run /learn periodically during long sessions to capture insights before context compaction.

Changes

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.
