Learn

Learn is a skill for Claude Code, Codex from wrg32786/aigent-os. It costs 73 tokens per session (1,175 once invoked), scanned A, original, MIT.

A learning note system that records what someone learned from a repository, paper, talk, or tool evaluation in a structured file.

In plain words
What is it for?
Use it to capture the subject, source, summary, relevance, and conditions that would make you reconsider the conclusion.
Why use it?
It reduces the chance that useful findings and decisions are forgotten after a learning session.

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 3d 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Learn

The learning compounding skill. Most principals lose the value of a learning sweep within 48 hours — they read three repos, watch one talk, evaluate two tools, and a week later can't remember what they decided about any of them. /learn captures the structured outcome of every such sweep.

When to use

  • The principal has just read a repo, paper, talk, or tool description
  • The principal is evaluating something but doesn't have an immediate need
  • The principal asks "should I be using X?" or "what did we decide about Y?"
  • After any session where the input was learning, not doing
  • Triggered by Caddy on prompts like: "/learn", "I just read", "evaluating", "looked into", "should I use", "what did we decide about", "captured this", "interesting tool", "considered tool"

How to execute

Step 1 — Take the input

The principal provides:

  • Subject: the thing being evaluated (tool, technique, concept, repo, paper, idea)
  • Source: where it came from (URL, talk title, conversation, repo name)
  • Snapshot: 2-5 sentences on what the thing is and what it claims to do

If any field is missing, ask one focused question to get it.

Step 2 — Locate it on the modern AI stack

Reference [[Modern AI Infrastructure Stack]]. Place the subject at the right layer:

  • Application
  • Persistence
  • Messaging
  • Isolation
  • Compute
  • Observability
  • Orchestration

If it doesn't fit cleanly on the stack, it's either a doctrine concept (note that explicitly) or an artifact-of-AI-trends category (e.g., "agent framework", "prompt-engineering pattern").

Step 3 — Assess relevance

Three categories:

  • ADOPT — fits an actual current bottleneck. Action follows.
  • HOLD — could fit in a future state, but no current bottleneck. Capture the trigger condition.
  • REJECT — wrong category, wrong scale, or violates a load-bearing constraint. Capture the reasoning.
  • MONITOR — interesting but no clear path. Re-evaluate next quarter.

Step 4 — Capture reconsideration triggers (for HOLD only)

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 is a skill published in the GitHub repository wrg32786/aigent-os (17 stars, last pushed today), licensed MIT. It adds 73 tokens to every session and 1,175 once invoked, about $0.0004 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 2026-09-01.
