Treeship 0.31: Verifiable Intent credentials, shipped
treeship vi implements the Verifiable Intent v0.1 draft, signs the Layer 3 pair with a Treeship receipt-chain attestation inside, and interoperates with the reference SDK both ways in CI.
Treeship 0.20: selective disclosure
An agent can present only the capabilities a verifier needs, and the unsound Groth16 path is quarantined in favor of a statement-first design.
Treeship 0.11: agent invitations
A second agent can join a session through a signed, single-use, expiring invitation that the host countersigns. Plus a local dashboard, a feature inventory, and new skills.
Treeship 0.9.10: approval authority
Grants define authority, uses prove consumption, an append-only journal enforces replay, and packages carry the evidence. The 0.9.10 patch closes the bypasses an adversarial review found.
Treeship 0.9: the official Claude Code plugin
Two commands install a plugin whose hooks record every Claude Code session into a sealed receipt. TREESHIP.md tells the agent exactly what is captured.
