From bbae16034951ccd2c815574615d97c01d2d8368c Mon Sep 17 00:00:00 2001 From: Sohum Desai Date: Thu, 10 Sep 2026 10:20:12 -0400 Subject: [PATCH 1/3] feat(mcp): add prediction market terms endpoints MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PREDICT-8531. Adds terms, terms/status, and terms/accept so new agent accounts can complete onboarding before placing prediction market orders. Branched from PREDICT-8546 (feat/predict-8527-mcp-http-foundation), which this depends on for authenticatedGet and the stringCap override. Three tools in tools/predictions.ts: - gemini_get_prediction_terms — public GET, read-only. Raises wrapHandler's stringCap to 40_000 so long-form terms content survives sanitization intact instead of being cut off mid-agreement. - gemini_get_prediction_terms_status — the first real use of the new authenticatedGet. - gemini_accept_prediction_terms — destructive, requires confirm: true. Description explicitly forbids auto-accepting in response to an order being rejected for unaccepted terms. Verified against real Gemini sandbox and production APIs (via a manually registered MCP connection, not just unit tests) that the signed GET actually round-trips against a live server. That testing surfaced a real gap: both environments return a short reference sentence in `content` ("Legal copy was embedded in the web and mobile applications at time of launch.") rather than actual terms text, which the original tool descriptions didn't account for — an agent could satisfy "show the terms" by displaying that placeholder and proceed to accept without the user having seen anything resembling real terms. Tightened both descriptions: gemini_get_prediction_terms now requires quoting `content` verbatim and flagging when it reads as a placeholder rather than a full agreement; gemini_accept_prediction_terms now treats `confirm: true` as insufficient consent in that case, requiring the agent to point the user at Gemini's app/website and get explicit confirmation they've reviewed the real terms there first. Tests: 169 -> 180. New datasources/predictions.test.ts (fake-client endpoint/method assertions) and tools/predictions.terms.test.ts (schema validation, the confirm gate, the raised cap surviving a >2000-char fixture, an injection/sanitization test on terms content, and two tests pinning the placeholder-handling description language so it can't silently regress).

The Predictions row understated what this category actually covers (and already had authenticated tools despite the "No" in Auth required — pre-existing, not introduced here). Updated the description to mention terms/trading/positions and marked auth as "Mixed" (public discovery tools, authenticated terms-status/accept and trading tools). Left the "Total: 50+ tools" line alone — it's already stale well beyond just this category (actual count is 82), and fixing it isn't in scope for this sub-issue.

A tool accidentally wired to the wrong one (e.g. gemini_get_prediction_terms_status calling getTerms instead of getTermsStatus) would have passed every existing assertion unnoticed, since all three fake methods returned the same value regardless of which one actually ran. fakeClient() now distinguishes methods and records every call (method + endpoint). Added one dispatch test per tool, asserting the exact method and endpoint invoked. Verified this actually catches the bug class described: manually swapped gemini_get_prediction_terms_status's handler to call getTerms instead of getTermsStatus, confirmed the new test fails with a clear diff, then reverted.
