What it does
SEO Audit is an agent skill from skrun-dev/skrun. Audit a website for SEO issues and track improvements over time. Use when analyzing website SEO performance.
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `agent.yaml`).
It sits in Marketing & SEO, covering SEO audit. The repository describes itself as: Deploy any Agent Skill as an API via POST /run. The open-source multi-model alternative to Claude Managed Agents, Microsoft Foundry & Mistral/Koyeb — works with any LLM. The licence is MIT.
When your agent uses it
- Analyzing website SEO performance
- Tasks that involve SEO audit
Example prompts
- “/seo-audit”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Analyze the website URL for common SEO factors
- Produce a score from 0 to 100
- State awareness: If previous audit state is provided, compare the current score with the previous one and indicate the trend (improving…
What it can do on your machine
Read from SKILL.md and the folder at commit b1d963b. 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 (its code samples are json).
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
SEO Audit loads about 392 tokens when it runs. Until then it costs about 30 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.
