Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability66
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 13432 tokens (~152/item across 88 items; 88 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

contacter_expert ~350

Call this ONLY when the user explicitly asks to contact, reach out to, or request a quote/appointment from a Payotte-listed professional. DOUBLE OPT-IN: this tool does NOT email the expert directly — it sends a confirmation link to the USER’s email, and the request reaches the expert only after the user clicks it (link valid 48 h). Tell the user to check their inbox. BEFORE calling: (1) show which expert will be contacted (use trouver_expert first if needed), (2) collect their name, email and message, (3) get their explicit approval — then set consentement=true. Never invent contact details. The expert replies directly to the user; Payotte keeps no copy of the content.

client_courrielstringyesEmail address of the user — the expert will reply there.
client_nomstringyesFull name of the user requesting contact.
client_telephonestring–Optional phone number of the user.

estimer_economie ~255

Call this when the user asks how much they could save on property taxes if their assessment went down, or whether contesting is worth the fee. Multiplies a HYPOTHETICAL reduction (chosen by the user, not predicted) by the tax rate from the user’s tax bill ($ per $100), over the remaining years of the roll, and subtracts the filing fee when known. Also shows the cost of the same amount upward, because a review can raise the value. Ask the user for their tax rate: Payotte does not guess municipal rates.

NameTypeReqDescription
annees_restantesnumber–Optional: years of the roll the reduction would cover (1-3).
baissenumberyesHypothetical reduction: in CAD (e.g. 30000) or as a fraction (e.g. 0.08 for 8%).
