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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00041 | $0.00996 |
| Opus 5.5 | $0.00016 | $0.00398 |
| Sonnet 5.5 | $0.00008 | $0.00199 |
| Haiku 4.5 | $0.00004 | $0.00100 |
Grade B, and why
learn scanned grade B with 1 finding 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.

91% identical to learn — 67 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/learn — Skill Extraction Workflow
Extract non-obvious discoveries into reusable skills that persist across sessions.
When to Use This Skill
Invoke /learn when you encounter:
- Non-obvious debugging — Investigation that took significant effort, not in docs
- Misleading errors — Error message was wrong, found the real cause
- Workarounds — Found a limitation with a creative solution
- Tool integration — Undocumented API usage or configuration
- Trial-and-error — Multiple attempts before success
- Repeatable workflows — Multi-step task you'd do again
- User-facing automation — Reports, checks, or processes users will request
Workflow Phases
PHASE 1: Evaluate (Self-Assessment)
Before creating a skill, answer these questions:
- "What did I just learn that wasn't obvious before starting?"
- "Would future-me benefit from this being documented?"
- "Was the solution non-obvious from documentation alone?"
- "Is this a multi-step workflow I'd repeat?"
Continue only if YES to at least one question.
PHASE 2: Check Existing Skills
Search for related skills to avoid duplication:
# Check project skills
ls .claude/skills/ 2>/dev/null
# Check global skills
ls ~/.claude/skills/ 2>/dev/null
# Search for keywords
grep -r -i "KEYWORD" .claude/skills/ ~/.claude/skills/ 2>/dev/null
Outcomes:
- Nothing related → Create new skill (continue to Phase 3)
- Same trigger & fix → Update existing skill (bump version)
- Partial overlap → Update with new variant
PHASE 3: Create Skill
Create the skill file at .claude/skills/[skill-name]/SKILL.md:

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 clearsmog/claude-skills (2 stars, last pushed 24d ago), licensed MIT. It adds 41 tokens to every session and 996 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (enumerates other installed skills). It is 91% identical to learn, differing in 67 lines, and is treated as a copy.
