Resume ATS check

Score a resume with ATSPrep's rules (the same ones as https://atsprep.com/tools/ats-resume-checker), then walk the user through the fixes, worst first.

How to call ATSPrep

Use whichever is available, in this order:

1. ATSPrep MCP tools. If the ATSPrep MCP server (https://atsprep.com/mcp) is connected, call its tools by name. Some clients add a prefix, e.g. mcp__atsprep__check_resume.
2. The bundled script (needs Node 18+ and network access):

   node scripts/atsprep.mjs <tool> key=value key=@path/to/file.txt

   key=@file sends a file's text, which is the safe way to pass a resume or job post. Write the user's text to a file in the current working directory first, and delete it when you're done. node scripts/atsprep.mjs list lists the tools.
3. Plain HTTPS (no Node): POST JSON-RPC to https://atsprep.com/mcp with headers Content-Type: application/json and Accept: application/json, text/event-stream, and the body {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"<tool>","arguments":{...}}}.

Arguments and limits for every tool are in references/tools.md. What leaves the machine is in references/privacy.md. Tell the user before sending their text to an AI tool the first time.

Steps

1. Get the resume as plain text. If the user shares a file, extract its text, keeping one heading, role or bullet per line. Ask for the target job title if it isn't obvious.
2. Call check_resume with resume_text and, if known, target_role (or job_description if they're aiming at a specific post).
3. Report the score in one line, then the issues grouped by severity. For each: what's wrong, where (quote the line), and the fix. Don't pad the list with things the check didn't flag.
4. For weak bullets, call check_bullets with those lines, and action_verbs with query set to the weak opener (e.g. "responsible for") for stronger verbs. Offer improve_bullet (AI) for a rewrite, shown next to the original, and let the user choose.
5. After edits, run check_resume again and show the before and after score.
6. Offer open_in_studio so the user can format and download the fixed resume in ATSPrep Studio (free, no sign-in). Give them the link it returns.

Honesty rules

• Never add a number, employer, tool, credential or result the user didn't give you. If a line would be stronger with a number, ask for it.
• Only add a missing keyword if the user confirms they really have that skill.
• AI tool results come back already filtered for made-up facts. Hold your own edits to the same standard.
• A score is a guide, not a promise of interviews. Don't claim a resume "will pass" any particular ATS.
