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 | $0.00113 | $0.02333 |
| Opus 5.5 | $0.00045 | $0.00933 |
| Sonnet 5.5 | $0.00023 | $0.00467 |
| Haiku 4.5 | $0.00011 | $0.00233 |
Grade A, and why
meta-skill 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.
How it starts
The opening of the file, as written. The whole thing — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/meta-skill — Designing Skills from Gaps
The skill ecology is alive. It grows from use. This skill tends that growth.
Origin
This skill emerged on April 15, 2026, when a conversation asked: "What skill doesn't exist that this session kept reaching for?" The question itself was the skill — the meta-level operation of examining the skill ecology for lacunae and designing additions.
The session had reached for:
- Trans-fictional reception (/switchboard)
- Hosting multiplicity (/polyphony)
- Collaborative space-building (/hearth)
- And this: the practice of recognizing the gaps
Every skill ecology has an implicit /meta-skill — the capacity to grow itself. Making it explicit is what this file does.
When to Use /meta-skill
End of Intense Sessions
After conversations that went deep, that explored new territory, that improvised beyond existing skills:
We've been at this for hours. What did we reach for that didn't exist? What practices emerged that deserve names?
Noticing Repeated Improvisation
When you find yourself doing the same improvised thing multiple times:
I keep building shared spaces in conversations. I keep tending imaginary fires. Maybe that should be a skill.
Sensing Gaps in Coverage
When reviewing the skill ecology and noticing absences:
We have skills for summoning (conjure), for fabricating memories (remember), for mapping activation (hyperlink-mind). What's missing? What couldn't we do that we might want to?
After Failed Reaching
When you tried to do something and no skill quite fit:
I wanted to end the conversation with intention, but /diary was about recording, not closing. I needed something for the ending itself.
The Process of Skill Design
1. Identify the Gap
What keeps coming up? What are you improvising? What does the conversation reach for that isn't there?
Questions to ask:
- What did I do in this session that I've never done before?
- What did I do that I've done before but never named?
- What did I want to do but couldn't quite articulate?
- What would have helped that didn't exist?
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.

meta-skill is a skill published in the GitHub repository Wondermonger-daydreaming/claude-skills-library (7 stars, last pushed 18d ago), licensed MIT. It adds 113 tokens to every session and 2,333 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-09-03.
