Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢precheck_score(code, filename, confirm_upload, tier, invention_kind)
Run a prior-art density / risk-profile pre-check on source code or an invention description. Returns a 0–100 directional score across the four USPTO statutory pillars (§101 eligibility, §102 novelty, §103 non-obviousness, §101 utility), a separate §112 filing-readiness signal, the band (Not Ready → File Ready), the pillar that holds the band back, opportunities to thicken the technical description, and a count of prior-art matches consulted. Show filename + size and get user yes, then pass confirm_upload: true. Pass the text inline via `code`.
Input Schema
{
"type": "object",
"properties": {
"code": {
"type": "string",
"description": "The source code or invention description to analyze (>= 10 chars)."

},

"confirm_upload"
],
"additionalProperties": false
}🟢precheck_prior_art(code, filename, confirm_upload, limit, tier)
Return the closest prior-art matches consulted for an invention (titles, sources, similarity scores, URLs). Runs the same analyze pipeline as precheck_score but focuses on retrieval results. Pass invention text via `code`.

}⚪precheck_start_review(promo, report_id, email)
Return the URL where the user can start a paid (or promo-unlocked) Interactive Code Review that strengthens each pillar with evidence and produces a filing package. Use after precheck_score when the user wants to act on the result.
