Best fit
Review function-calling tool definitions before exposing them to an agent.
// agent-native
Tool Schema Linter
Lint the function-calling tool definitions your agent exposes, so it picks the right tool instead of the wrong one or none.
Format: Agent skill, not a browser app. You need an AI agent that can load its instructions and use the required tools.
Package requirements: Agents that read the open SKILL.md format. Verify runtime and service requirements at the purchase or install destination.
You get: Findings on missing descriptions and types, overlapping tools, selection complexity and missing safeguards around sensitive operations.
Licence and purchase details
Review the package licence at the destination.
Review the offer and access method at your chosen marketplace. Agensi provides connected-agent access, not a download. Buying a skill does not include an AI-agent subscription or setup service.

How to run

Good to know
This is heuristic; the unsafe-tool rule is advisory. It is distinct from REST API tooling: this targets function-calling definitions.
