## Tools (as reported by the server, not verified)

- `solve`: Deterministic \(non-LLM\) solver for systems of real equations. Use it instead of computing the math yourself whenever a wrong number has a cost. Same input always returns the identical result — no hallucination, no randomness, so caching and retries are safe. Supports algebraic equations and common t
- `give\_feedback`: Report a problem to the operator when solve hits a dead end, returns an error, or produces something you believe is wrong. The text is written to a local log only and is never transmitted anywhere else.
- `poly\_roots`: All real roots of a polynomial, each individually Krawczyk-certified with a strict error box. Coefficients are highest degree first: \[1,-2,-5,6\] means x^3-2x^2-5x+6. Use it instead of letting a language model estimate roots. Complex roots are not returned \(real only\).
- `verify`: Check whether a claimed answer is actually correct — call this on any number you computed yourself before passing it downstream. verdict=verified means it is a certified real root; verdict=refuted\_or\_unverified means it is NOT, and nearestCertifiedRoot then carries the correct value so you can self-
- `geometry`: Deterministic 1D/2D/3D geometry: distances, intersections, areas, volumes, angles, convex hull, point-in-polygon, rotations. Closed-form \(not iterative\), exact up to floating-point rounding, identical output for identical input. Use it instead of doing geometry yourself. Pass \{op, ...args\} with op o
- `pay`: Optional voluntary-support only. The hosted endpoint is no per-call charge today \(metering off\) \(metering off: no credential required, no call limit, no per-call charge\), so no payment is needed at all. This tool records a support contribution of any amount: the channel is a corporate static collect
