Today nothing reaches npm between two release-please releases, so trying a merged but unreleased change means building from source. This adds a continuously published preview channel. Every CI-green push to `main` that is not a release merge publishes `<package.json version, patch bumped>-preview.N` under the `preview` dist-tag, tags the commit `v<version>`, and dispatches the same agent registry update a stable release does. With `main` at 0.73.0 that gives `0.73.1-preview.1`, `0.73.1-preview.2`, and so on; `N` restarts at 1 whenever a release moves the base. `latest` is untouched. ## Approach - **Added to `publish.yml` rather than a new workflow.** npm binds a trusted publisher to one repo + workflow filename, and a package gets only one. A separate file would fail OIDC and cost the stable path its publisher. - **Gated on the `CI` workflow succeeding** (`workflow_run`), so a red commit is never published. release-please's release merge is excluded by the head commit's author and subject — its `releases_created` output is not reachable from a different workflow run. - **`N` is the max of the npm registry and local git tags.** npm reserves versions forever, even after `unpublish`, so a reused `N` is a hard failure; but the registry is CDN-served and lags, which the tags cover. A registry read failure aborts rather than guessing. - **Base is patch+1, not release-please's prediction**, which moves mid-flight and would reset `N` under already-published previews. - **The version is applied to the CI working tree only**, never committed — `package.json` and the release-please manifest stay release-please's to own. - **`--tag preview` is mandatory:** `npm publish` defaults to `latest` even for a semver prerelease. - **Three jobs.** `publish-npm-preview` mirrors `publish-npm` and only publishes (no repo write access); `publish-tag-preview` only tags, so a failed tag is retryable with _Re-run failed jobs_ without re-publishing an immutable version; `trigger-registry-update` is shared with the stable path. Both downstream jobs gate on a `published` output the publish step sets, not on job status — the tag push happens after the publish, so a red job can still mean npm has the version. ## Next step The publish is `npm publish --dry-run` for now. The `workflow_run` trigger and the `release` environment's protected-branch policy mean this job cannot run off the default branch at all, so merging this is the only way to exercise the trigger, the gate and the version calculation — and with `published` unset, the rehearsal neither tags nor touches the registry. Once one run looks right, a follow-up drops `--dry-run` and adds `echo "published=true" >> "$GITHUB_OUTPUT"` to that step. Nothing else changes.
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
- Tool permission presentation, editable choices, and durable effects through the permission extension
Learn more about the Agent Client Protocol.
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.
