learn

learn is a skill for Claude Code from isvlasov/rageatc-oss. It costs 32 tokens per session (298 once invoked), scanned A, original, MIT.

A quick way to record an observation in a project's LEARNINGS.md file for possible improvement later.

In plain words
What is it for?
Capturing what went wrong or worked well during a coding session.
Why use it?
It keeps useful lessons from being forgotten without requiring a full investigation at the time.

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 7d 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.

What it actually says

Learn

Capture an observation to LEARNINGS.md so it is preserved for future sessions and later /codify sweeps.

This is quick capture, not analysis — root cause analysis happens later, when the user runs /codify. Record what happened clearly enough that a future reader can understand it without this session's context.

Steps

  1. Locate or create LEARNINGS.md in the project root. If it does not exist, create it using the LEARNINGS.md template in the scaffolding-project skill (current frontmatter format lives there).
  2. Draft the entry from session context. With no arguments, the user is signalling "that was noteworthy — record it": draft your best understanding and ask "Here's what I'd capture — does this match how you see it?". With an argument, fold the user's pointer or perspective into the draft. Either way you write the entry; the user confirms or corrects — they should not have to explain the event from scratch.
  3. Append the entry following the format in the file's frontmatter comment. Distil, do not transcribe.
  4. Confirm — tell the user what was recorded and where. Nothing else needed.

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.
