SYSE.52:4.3 - Construct the tool view and recovery path

Expose operations relevant to the supported next moves with their actual input, output and effect semantics. Use real preconditions to distinguish selectable, presently executable and unavailable operations. An unmet execution precondition may justify retaining the observation or recovery operation that can resolve it. Semantic similarity alone is insufficient for filtering.

Check what the reduced view would do after a malformed return, missing observation or uncertain effect. Keep the permitted fallback reachable. Preconditions establish applicability, not permission; current authority and resource conditions still govern actual invocation through SYSE.42.

Assemble the actual arrangement and make its tools usable by the named performer. A sheet needs the relevant visible area and a usable means of recording the next operation; an available calculator needs readable input and output. For a technical agent, assemble the actual request with the system’s supported separation between governing instructions and untrusted source content. Retain the binding between source return and the claim it supplies. If a pointer must be followed, budget that acquisition and ensure the next step can request it.
