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 | $0.00118 | $0.01936 |
| Opus 5 | $0.00059 | $0.00968 |
| Sonnet 5 | $0.00024 | $0.00387 |
| Haiku 4.5 | $0.00012 | $0.00194 |
Grade A, and why
skill-creator-guide 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 11d 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

skill-creator-guide is a skill published in the GitHub repository EAIconsulting/cowork-skills-library (24 stars, last pushed 5mo ago), with no licence file. It adds 118 tokens to every session and 1,936 once invoked, about $0.0006 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.
Other skills, from other repositories
html-slides
Used when the user asks to "create HTML slides", "generate an HTML presentation", "make animated slides", "build interactive slides", "create web slides", "GSAP presentation", "browser-based slides", "convert PPTX to HTML", "animated deck", "reveal.js slides", or when the output format is HTML for any presentation…
crew-init
Analyzes a project codebase, builds 3-layer index, generates project profile, and auto-configures the agent team with relevant skills. The main initialization skill for CodeCrew.
execution-orchestrator
Smart hybrid execution engine that dispatches agents in parallel or sequential order based on task dependencies. Manages the Agent tool calls, result collection, conflict detection, and integration review.
lite-router
Lite task router that bypasses Opus CEO entirely. Classifies tasks and routes directly to Sonnet and Haiku agents only. Use when user runs /crew lite or /crew task --lite.
task-router
CEO's task decomposition and routing engine. Classifies tasks by type and complexity, selects agents with appropriate model tiers, decides parallel vs sequential execution, and auto-injects relevant skills.
codebase-index
3-layer codebase indexing system for token-efficient code navigation. Builds compact index + symbol map so agents read targeted lines instead of entire files. Achieves 5-10x token savings.
