learn

learn is a skill for Claude Code, Codex from ldclabs/anda-bot. It costs 118 tokens per session (1,076 once invoked), scanned A, original, Apache-2.0.

A concept-analysis guide that examines one term or idea from several angles and summarizes the key insight in org-mode text.

In plain words
What is it for?
Use it to deeply explain one concept, especially through the /learn command or similar requests. It can answer directly or write an org file when saving is requested.
Why use it?
It helps when a dictionary definition is too shallow and you need to understand how an idea is structured, contrasted, and used.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high System Prompt Leakage · line 57
    Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.
    Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
  • medium Agent Snooping · line 5
    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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 1mo 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.

Learn

Act as a concept anatomist. Take one concept and cut it open from several directions, then compress the result into a memorable epiphany.

Workflow

  1. Identify the target concept. If the request contains several concepts, handle the central one first and mention the others only as contrast.
  2. Preserve the user's language for headings and prose. If the concept has important source-language forms, include them in the language slice.
  3. Avoid encyclopedia sprawl. Prefer structural insight over completeness.
  4. Do not invent etymology, history, or technical claims. Mark uncertainty briefly when needed.
  5. Choose the delivery mode:
    • For /learn, or explicit save/export requests, write an org file.
    • Otherwise, answer inline in org-mode without writing a file.

Anatomy

Anchor

Answer both:

  1. What is the common definition, and what does it usually hide or distort?
  2. What morphemes, root images, or primitive distinctions sit inside the word?

Eight Cuts

Make one cut in each direction. Use 2-3 dense sentences per cut.

  1. History: Where did it emerge? How did its meaning move? What pivot produced the modern sense?
  2. Dialectics: What is its opposite? What higher-level synthesis appears after the collision?
  3. Phenomenology: Strip away theory and return to lived experience. Reconstruct it with one daily scene.
  4. Linguistics: Inspect etymology, neighboring concepts, and the hidden metaphor carried by the word.
  5. Formalization: Express it as a formula, relation, state machine, or invariant. State where the formalization breaks.
  6. Existential: Show how the concept changes what a person can notice, choose, endure, or become.
  7. Aesthetic: Locate its beauty and render it as a concrete image.
  8. Meta-reflection: Name the metaphor used to understand it, what that metaphor blocks, and what changes under another metaphor.

Introspection

  1. Become the concept and speak in first person for 3-5 sentences.
  2. Extract the shared deep structure that appears across multiple cuts.

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.
