What it does
Yao Expert Skill is an agent skill from yaojingang/yao-open-skills. Create expert-level learning reports and tutorials from any domain, industry, technology, role, market, product idea, or vague field question. Use when the user wants to quickly build domain expertise, understand an industry, generate a structured expert study report, build a keyword library, design Feynman self-tests, or export the result as Markdown, DOCX, PDF, and HTML. Do not use for short factual answers, pure business model diagnosis, standalone beginner tutorials with no domain-structure research, simple…
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 47 other files, including scripts and reference files (for example `README.md`, `agents/interface.yaml` and `evals/semantic_config.json`).
It sits in Documents & Office, covering Word documents, Document parsing and Product strategy. It works with Microsoft Word. The repository describes itself as: OpenYao public skills collection: reusable AI assets for decision-making, business analysis, tutorials, research evidence gathering, and document generation. The licence is MIT.
When your agent uses it
- The user wants to quickly build domain expertise
- Understand an industry
- Generate a structured expert study report
- Build a keyword library
Example prompts
- “/yao-expert-skill”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Read references/domain-expert-method.md; capture assumptions and the expert-learning brief.
- Read references/research-and-source-quality.md; build a source plan and verify current facts when the domain is time-sensitive.
- Draft the canonical report in Markdown using templates/expert-report-template.md.
- Add the tutorial path, keyword teaching cards, concept map, representative people/company/case map, Feynman tests, evidence register, and…
- Read references/report-and-tutorial-contract.md; check section coverage, evidence labels, and learning sufficiency.
- Read references/export-and-layout-quality.md; run scripts/export_expert_report.py for Markdown, DOCX, PDF, and HTML.
- Run scripts/validate_artifacts.py and fix layout, table, anchor, overflow, citation, and local-path issues before delivery.
What it can do on your machine
Read from SKILL.md and the folder at commit 093996e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/, which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Yao Expert Skill loads about 1.7k tokens when it runs, and up to ~9k if it reads all its reference files. Until then it costs about 145 tokens; SKILL.md has 776 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Yao Expert Skill
Turn a domain, industry, technology, role, product direction, or fuzzy idea into an expert learning packet: one structured report, one tutorial path, a keyword system, Feynman tests, and four polished export formats.
Own The Following Job
- Normalize the user's topic into domain, region, purpose, audience, time horizon, output depth, and exclusions.
- Build domain expertise from structure first: boundary, classifications, value chain, actors, demand, supply, competition, lifecycle, policy, technology, capital, risks, and change variables.
- Use authority-first research and separate
fact,inference,hypothesis, andunknown. - Generate
50-100keyword teaching cards. Each keyword must include a plain-language one-liner, concept explanation, bottom logic, real example, practical application, role/effect, related people/companies/institutions when relevant, common misconception, and evidence. - Explain difficult concepts and underlying logic with simple analogies plus real domain examples, so a newcomer can understand how the field works rather than only memorize terms.
- Begin every report with a reader-facing
导读摘要that introduces the learning material, highlights, reading path, and structural logic before the formal report sections. - Write each major module with a natural introductory paragraph and transitions before tables, so the report reads as coherent learning material instead of a hard glossary or matrix dump.
- Generate
10Feynman questions with reference answers and a scoring rubric. - Produce Markdown, Word, PDF, and HTML artifacts, with layout checks for tables, borders, overflow, anchors, fixed left-side navigation, and local-path leakage.
Inputs
Expect one or more of:
- a domain, industry, technology, market, role, company direction, or vague idea
- geography, language, audience, use case, time horizon, and desired depth
- existing notes, links, papers, reports, screenshots, or source constraints
- requested output formats, naming, style, deadline, and privacy constraints
When the user gives only a topic, do not stall. Use the defaults in references/domain-expert-method.md, state the assumptions, and continue unless a missing input would materially change the package.
Do Not Route Here
- one-off factual answers or quick explanations
- generic web research that does not produce an expert learning packet
- pure business model work; use a business model skill instead
- beginner tutorial creation with no industry/domain structure; use a tutorial skill instead
- finished-file conversion with no report or tutorial design
- legal, medical, financial, or safety advice as a final recommendation; keep those as educational research with source and uncertainty notes
Default Workflow
- Read
references/domain-expert-method.md; capture assumptions and the expert-learning brief. - Read
references/research-and-source-quality.md; build a source plan and verify current facts when the domain is time-sensitive. - Draft the canonical report in Markdown using
templates/expert-report-template.md. - Add the tutorial path, keyword teaching cards, concept map, representative people/company/case map, Feynman tests, evidence register, and uncertainty log.
- Read
references/report-and-tutorial-contract.md; check section coverage, evidence labels, and learning sufficiency. - Read
references/export-and-layout-quality.md; runscripts/export_expert_report.pyfor Markdown, DOCX, PDF, and HTML. - Run
scripts/validate_artifacts.pyand fix layout, table, anchor, overflow, citation, and local-path issues before delivery.

Output Contract
The normal output set is:
{basename}.md: canonical expert learning report and tutorial packet{basename}.docx: Word document export with readable tables and restrained report styling{basename}.pdf: PDF export checked for page layout and table overflow risk{basename}.html: standalone HTML report with a fixed left-side numbered navigation menu and section anchors- a short delivery note with assumptions, source coverage, uncertainty, validation result, and next learning steps
Quality Gates
- The topic boundary includes wide, narrow, exclusion, and data/source scope.
- The report begins with
导读摘要, including introduction, highlights, reading path, and logic overview; Markdown, DOCX, PDF, and HTML exports must all preserve this opening summary. - Every major module has a reader-facing introduction before dense tables or matrices.
- Key claims are backed by source tier, date, and confidence.
- Every major judgment is labeled as fact, inference, hypothesis, or unknown.
- Keyword teaching cards cover demand, product, technology, value chain, business model, competition, policy, finance, operations, risks, and trends.
- Every keyword teaching card explains: what it means, how to understand it in one sentence, why it exists, how it works, where it appears in the real domain, how to apply it, what role it plays, which people/companies/institutions are associated with it when relevant, and what beginners often misunderstand.
- Representative people, companies, institutions, products, and cases are included as learning anchors, with role labels and source notes rather than unsupported rankings.
- The tutorial can take a beginner from orientation to self-check, not just list terms.
- HTML contains a fixed left-side navigation tree with ordered indices, compact four-character Chinese anchor labels, transparent background, and no standalone sidebar panel styling.
- PDF exports remove the HTML navigation node before printing and hide browser print chrome; no navigation labels,
file://paths, dates, or browser page footers should appear. - DOCX/PDF/HTML exports exist and pass
scripts/validate_artifacts.py, or remaining failures are named precisely.
