finslipa_check · Finsliparn MCP: Risk & Policy

WHAT IT DOES

What finslipa_check does on Finsliparn

AI agents invoke finslipa_check to trigger actions in Finsliparn. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why finslipa_check needs a policy

The tool actively executes the test suite, scores results, and modifies directives based on outcomes. Running tests constitutes executing code/external operations, and updating directives is a write side-effect. Since it both executes and writes, Execute is the higher severity category. Blast radius is high because arbitrary test execution could trigger unintended side effects depending on the test suite content.

From the tool's definition "Run tests, score the current iteration, and update the directive with feedback"
