ASM turns eligibility, cost, risk, provenance, and policy into a reproducible decision before an agent invokes a service or pays it.
Across five registries and directories, no entry combined comparable price, SLA/rate-limit, quality, and access-mechanism signals in machine-actionable form. Runtime payment remains the selected rail's job. Snapshot: May 2, 2026.
In ToolSelect-Bench v0, every tested model improved correct selection with ASM metadata; constraint violations fell for five of six. Raw picks are committed for rescoring.
The selector rejects ineligible tools and surfaces financial risk and approval requirements. This uses expired June 2026 example facts, not current provider recommendations.
