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 | $0.00093 | $0.00972 |
| Opus 5 | $0.00046 | $0.00486 |
| Sonnet 5 | $0.00019 | $0.00194 |
| Haiku 4.5 | $0.00009 | $0.00097 |
Grade A, and why
skill-creator 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 5d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Creator — Skill Smith
"Build your own skills"
When to use
- "Make me a skill for " — anything you've done three times deserves a SKILL.md
- "Turn this workflow into a skill" after a session that went well
- "Add a new employee to " in this repo
- "My skill never triggers" / "the wrong skill fires" — description surgery
- Standardizing a process so the whole team runs it the same way
Workflow
- Interview for the job-to-be-done: the task, three real phrasings the user would type to ask for it, available inputs, the artifact that means "done", and what must never happen.
- Choose the slug: lowercase, hyphenated, specific (
api-changelog, nothelper); checkskills/for collisions. - Write the description before the body — it is the trigger. Third person, capability first, then "Use when ..." quoting the phrasings from step 1. Hard limit 500 characters.
- Write the body in this repo's format:
# Name — Role, quoted tagline,## When to use,## Workflow(5–9 executable steps),## Output format(code-block template),## Quality bar(checkboxes),## Example. - Save to
skills/<slug>/SKILL.md— directory name must equal frontmattername, exactly. - Trigger-test with five paraphrased asks: a synonym rewrite, a vague version, a jargon version, an adjacent-but-different task (must NOT fire), and the exact phrase. Judge each against the description alone.
- Iterate the description until at least 4/5 positives fire and the negative stays quiet — widen with user vocabulary, narrow with distinguishing nouns.
- Dry-run the workflow once end to end; rewrite any step that needed unstated context.
Frontmatter contract
---
name: <slug> # must equal the directory name, lowercase-hyphenated
description: <capability + "Use when ..." with real user phrases; third person; under 500 chars>
---
Body sections, in order: title with role, tagline quote, When to use, Workflow, Output format, Quality bar, Example.
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.
- 5d ago First seen · 79 lines · 93 tokens per session scan A 575426cd84f2
skill-creator is a skill published in the GitHub repository alebgl77/claude-inc (14 stars, last pushed 2d ago), licensed MIT. It adds 93 tokens to every session and 972 once invoked, about $0.0005 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 2026-08-30.
