@agentproto/provider-kit

Generic provider/backend catalog, status, creds, setup-ledger, list/resolve, MCP tool, and CLI wizard primitives shared by the agentproto provider families (agent-CLI, browser, tunnel, and eval-reporter backends).

The kit owns the skeleton; each family parameterises it with its own TInfo descriptor and THandle (which extends AdapterHandle). The runtime keeps importing zero concrete providers — everything flows through injected load / toInfo callbacks.

| Export | Module | Purpose | |---|---|---| | computeStatus | ./status | Pure sync supported \| available \| ready classifier | | makeCredsStore | ./creds | File-backed creds store, mode 0600, never leaks value | | makeSetupLedger | ./ledger | ~/.agentproto/setup/<slug>.json existence/read/write | | makeAdapterResolver, makeAdapterLister | ./list-resolve | Slug→handle + catalog→entry list | | makeListTool, makeSetupTool | ./mcp-tools | MCP tool factories (value param is sensitive) | | makeAdapterWizard | ./wizard | CLI radio-picker + step runner; skips ledger-completed steps |

See docs/provider-kit.md for the full design (the kit's concepts are unchanged; only the package name was renamed from @agentproto/adapter-kit).

Status engine is pure & sync (fed pre-resolved booleans). AdapterHandle.check() is async and never invoked during listing — status comes from resolvability plus ledger/creds existence only.

The previous package name @agentproto/adapter-kit remains available as a deprecated shim that re-exports @agentproto/provider-kit unchanged.
