Example prompts
- “/schema-validator”
What it can do on your machine
Read from SKILL.md and the folder at commit f818ba8. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Schema Validator loads about 369 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 181 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); files beside SKILL.md are not scanned.

Schema Validator
Purpose
Validate structured data against visible page content and verified runtime or merchant data.
When to use
Use when reviewing Product, Offer, AggregateRating, BreadcrumbList, Organization, WebSite, or related structured data.
Inputs
- JSON-LD, HTML, or template source;
- visible page values and runtime data when available;
- the expected schema type and route scope.
Required checks
- Trace every commercial value to runtime or verified merchant data.
- Do not synthesize ratings, review counts, prices, stock, GTINs, SKUs, materials, or shipping details.
- Check duplicate Product graphs and conflicting offers.
- Treat a value that only exists in schema, but not in a verified source, as unsupported.
- Prefer removal of unsupported properties over invented completion.
Output contract
Report each issue using the PROTOCOL.md finding contract and identify the exact property and evidence path.
Failure conditions
- Missing source or runtime evidence: mark the property
UNKNOWNor unsupported. - Never invent ratings, review counts, prices, stock, GTINs, SKUs, materials, or shipping details.
- Do not call a graph valid solely because it parses as JSON.
Verification
Run schema fixtures and deterministic evals; compare emitted properties with visible or verified values.
