Schema Quality & AI Usability70
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 553 tokens (~276/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

MCP tools — 2 exposed · ~380 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. 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.

Tool Tokens
close_session ~186

Finalize a Pay-As-You-Learn tutoring session and return its itemized, attested invoice. Seals the ledger for the given sessionId: status flips to "closed", a SHA-256 attestation is stamped over the line items and total, and no further questions can be billed to this session afterward. Returns sessionId, createdAt, closedAt, questionCount, the full lineItems array, the totalAtomics / totalUsd owed, and the attestation hash. Closing itself is FREE and moves no funds — the learner was already charged per answered question; this only produces the final receipt. Idempotent: closing an already-closed session returns the same total. Use load_session first if you want to review the tab before sealing it.

load_session ~194

Read the running tab for a Pay-As-You-Learn tutoring session by its sessionId. Returns the itemized ledger: one lineItem per answered question (question text, level, output tokens, per-item cost in USDC atomics and a "$x.xxxxxx" string, and the timestamp), plus the session status ("open" | "closed"), questionCount, and the running totalAtomics / totalUsd. If the session was already closed it also returns the finalized, attested invoice. A sessionId with no stored history returns an empty open session (questionCount 0) rather than an error — that is an honest "nothing billed yet", not a failure. Viewing the tab is always free; this never charges the learner. Read-only live data.
