Claude supplies structured patches for Edit and Write, but ACP diff blocks previously carried only the reconstructed texts. AIR had to compare those texts again to display added and removed counts. Count patch operations in the existing conversion loop and publish `_meta.jetbrains.air.diffStats` on each diff block. This uses the same contract as https://github.com/agentclientprotocol/codex-acp/pull/501. Each block has its own counts. No extra traversal, full file comparison, or navigation calculation is needed. Omit statistics when patches are absent or inconsistent, so clients retain their existing fallback. Exclude EOF markers from the displayed texts. Document the extension and cover per-block counts, Edit and Write hooks, EOF changes, and fallback behavior. Validation: - `npm run build` - `npm run check` - `env -u ANTHROPIC_BASE_URL npm run test:run` (the local endpoint override affects unrelated provider tests)
ACP adapter for the Claude Agent SDK
Use Claude Agent SDK from ACP-compatible clients!
This tool implements an ACP agent by using the official Claude Agent SDK, supporting:
- Context @-mentions
- Images
- Tool calls (with permission requests)
- Following
- Edit review
- TODO lists
- Nested subagent transcripts
- Interactive (and background) terminals
- Custom Slash commands
- Client MCP servers
- Session-scoped long-running goals through the provider-neutral goal extension
- Structured errors, recovery, and warnings through the opt-in session failure extension
- Concrete model and effort defaults through the opt-in recommended config value extension
- Tool permission presentation, editable choices, and durable effects through the permission extension

To try changes that have landed on main but are not released yet, install from the
preview channel — every push to main publishes one. See
docs/RELEASES.md.
npm install @agentclientprotocol/claude-agent-acp@preview
Subagent sessions
Subagents are exposed only after bilateral capability negotiation. Until the released ACP SDKs
preserve the draft clientCapabilities.subagents field, a supporting client may advertise
nativeSubagentSessions in _meta.jetbrains.air.capabilities; the adapter mirrors the capability
in its initialize response. The canonical field remains supported and takes precedence once it is
available. Without either client signal, Agent/Task lifecycle keeps its legacy ordinary ACP
tool-call representation and child interactions stay on the root session. Clients that use the
historical _meta["subagent-transcript"] capability or forwardSubagentText session option retain
the flattened child transcript behavior.
