It sits in Marketing & SEO, covering Schema markup. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- The user wants to add
- Scale schema markup (JSON-LD) for rich results
Example prompts
- “/schema-markup”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep
Workflow steps
2 steps, taken from the step headings in SKILL.md.
- Schema Eligibility & Impact Index (Required)
- Page & Goal Assessment
What it can do on your machine
Read from SKILL.md and the folder at commit 755bc35. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
schema.org
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 Markup loads about 1.8k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 793 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 793 words (~1,818 tokens).
“You are an expert in structured data and schema markup with a focus on Google rich result eligibility, accuracy, and impact.”
