yaojingang/yao-open-skills is a public collection of reusable AI skills for research, decision-making, business analysis, learning, and document creation. It serves people who want repeatable, maintainable AI workflows instead of isolated prompts, and catalogued add-ons are published skills from this collection.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.01150 |
| Opus 5 | $0.00036 | $0.00575 |
| Sonnet 5 | $0.00015 | $0.00230 |
| Haiku 4.5 | $0.00007 | $0.00115 |
Grade A, and why
yao-open-skills-sync 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 13d 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 — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Yao Open Skills Sync
Use this skill to manage the public yao-open-skills collection in the current repo root.
This skill is not for creating arbitrary new skills from scratch. It is for intake, governance, sync tracking, and collection maintenance.
Read First
Before changing the collection, read:
references/operating-rules.mdreferences/registry-schema.md
Only read repo-wide docs under ../../docs/ if you need more human-facing detail after reviewing the references.
Primary Responsibilities
- Evaluate whether a local skill is suitable for public release
- Create a clean public copy under
skills/<slug>/ - Register or update the skill in
registry/skills.json - Add or update a human-facing usage guide under
docs/skills/<slug>.md - Regenerate the README catalog and HTML navigation page so the collection homepage stays in sync
- Record whether the skill is only local, staged, published, or needs an update
- Push collection changes to GitHub when the user wants the public repo updated
Workflow
1. Inspect the source skill
Given a local path from the user:
- Confirm the path exists
- Inspect
SKILL.md - Identify what should be kept, removed, or rewritten for public release
Watch for:
output/,downloads/,.venv/,node_modules/, caches, logs- generated reports, exported results,
.commandhelpers, and local scan artifacts - private APIs, tokens, cookies, internal references, customer data
- assets or references that may not be redistributable
2. Decide whether it can be public
Use the publishing rules:
- If the skill can be cleaned into a self-contained public version, proceed
- If it mixes public logic with sensitive material, split the public part from the private part
- If it cannot be safely cleaned, stop and explain why it should not be published
3. Import the public copy
When approved:
- Copy the public version into
skills/<slug>/under the repo root - Keep only the files needed for the public skill
- Make the structure self-contained and understandable
- Exclude local output artifacts by default unless the user explicitly wants a safe sample included
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

yao-open-skills-sync is a skill published in the GitHub repository yaojingang/yao-open-skills (1,314 stars, last pushed 15d ago), licensed MIT. It adds 73 tokens to every session and 1,150 once invoked, about $0.0004 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.
