What it does

Pre Launch SEO Check is an agent skill from spronta/crawlie. Run a pre-launch / pre-deploy SEO gate on a site or set of pages with crawlie, returning a clear pass/fail. Use when the user is about to launch, deploy, or ship and wants to verify there are no blocking SEO issues (broken links, 5xx, missing titles/canonicals, noindex slips), or wants a CI gate for SEO regressions. Works even if crawlie is not installed.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO. It works with Model Context Protocol. The repository describes itself as: Fast, free, open-source technical SEO + GEO crawler: built for humans and agents.

When your agent uses it

  • The user is about to launch
  • Ship and wants to verify there are no blocking SEO issues (broken links
  • Missing titles/canonicals
  • Wants a CI gate for SEO regressions

Example prompts

  • “/pre-launch-seo-check”

Requirements

  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Prefer mcpcrawlie* tools if present this session.
  2. Else CLI prefix: crawlie if on PATH, otherwise
  3. If neither is available, ask for Node (https://nodejs.org) or the crawlie MCP, then stop.

What it can do on your machine

Read from SKILL.md and the folder at commit 810e836. 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

    Shell commands in SKILL.md call:

    • npx
    • npm
    • claude

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • nodejs.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

Pre Launch SEO Check loads about 758 tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 334 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~758

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 334 words (~758 tokens).

“A go / no-go gate: crawl the target, apply blocking thresholds, and report a clear verdict with the exact blockers. Built for "are we safe to ship?" moments and CI. crawlie ships on npm as crawlie — no pre-install, no…”
