Added "vc_agent_proof", "vc_lease_consume", "vc_lease_issue" and 4 more (26 tools before, 33 now)
Verify an agent's completion claim against real external world state. Runs independent read-back checks (HTTP status, page text, JSON fields) and returns a digest receipt with verified=true/false plus a confidence score, so a user does not have to trust the agent's self-reported summary. Use after an agent says it posted, deployed, paid, emailed or changed a record. ~$0.25/call.
Spend exactly one use of a lease, atomically. Blocks replay, expiry, revocation and overuse. Returns decision allow/block with a named reason plus an Ed25519 decision receipt. If a previous attempt timed out, call this again with the SAME use_nonce: a replay returns reason=replay — do not retry the write, reconcile it. ~$0.02/call.
Mint a durable single-use capability lease, or attenuate a parent lease. Use before an irreversible action you may need to retry: pass a stable use_nonce to vc_lease_consume so a retry after a timeout blocks instead of writing twice. Authority is conserved — a child's uses are reserved out of the parent, so a 1-use grant cannot father N free children. ~$0.05/call.
Revoke a lease and (by default) its whole subtree so derived authority dies with its source. Use when an agent is misbehaving or a task is cancelled. ~$0.02/call.
Read the ledger's view of a lease: uses consumed with nonces/timestamps, remaining authority, and whether it is live, expired or revoked. ~$0.01/call.
Get details for one Vibes-Coded marketplace resource. Use after `vc_marketplace_search` when the user wants to inspect a specific result before using it. Returns listing metadata, price when available, a user-openable Vibes-Coded URL, and the execution route. Read-only and does not execute or purchase the resource.
Search the Vibes-Coded marketplace for AI-agent tools and API outcomes. Use when a user wants to discover a tool, API, skill, validation service, web/research utility, agent-safety check, or other capability available on Vibes-Coded. Search by the user's actual task and return relevant listings. This tool only searches Vibes-Coded's bounded marketplace catalog. It does not execute a paid outcome, change user data, or search the general web. Prefer this before `pay` when the user has not already chosen a specific Vibes-Coded outcome. …
