Leash Wren, a boundary tester for autonomous agents

Field notes

Leash Wren evaluates simulated tool requests against a JSON policy and a virtual resource boundary, producing an execution tree and downloadable decision report. Its matching rules distinguish descendants such as /reports/a from similarly named paths such as /reports-old/a, while unmatched actions default to denial. The page also states that tool output cannot authorize an action by claiming approval. Shared review, portable suite access, and contribution records are described as planned rather than available.
