feat(acp): add DeepSeek Harness and ZCode to the registry - #32943
ACP Registry search cannot install DeepSeek Harness or ZCode. Neither agent is in the official registry index. Discussion #11937 asked for DeepSeek Harness and was closed with the existing ACP path: dsh --profile acp. A dedicated DSH driver (#14026) is the wrong shape.
On Windows, the npm launcher for that CLI is dsh.cmd. T3 refuses generic batch files, so the installed command cannot start. A typed local ACP command also closed the add dialog instead of offering the same sign-in step as a registry agent.
Change
When the official registry URL is loaded, T3 appends two records only if those ids are absent. The cached official JSON is unchanged.
DeepSeek Harness installs @deepseek-ai/dsh@0.2.2-rc.1 and starts dsh --profile acp. Credentials stay in the dsh profile. The earlier live probe advertised no login method, so the sign-in step can be skipped.
ZCode installs the unofficial supermomonga/zcode-acp v0.3.2 raw binaries (checksums from that release's SHA256SUMS) and starts zcode-acp. A compatible ZCode desktop install is still required. This is not zcode-acp-server.
Local ACP commands now continue to the existing sign-in step. Until a finished probe reports zero auth methods, an installed local command offers that step. A probe that advertises methods shows sign-in even when the snapshot still says authentication is unavailable.
On Windows, a standard npm Node cmd shim is rewritten to node.exe plus its script and arguments, with shell: false. Custom batch files stay rejected.
These pieces belong together: the registry records are how Add installs the CLIs, the shim is how the Windows npm launcher for dsh actually starts, and the sign-in step is the account flow those installs already use.
Scope and approval
This stays on the existing ACP registry driver. It does not add a provider package, agent-id checks in the generic adapter, or a new auth protocol.
There is no maintainer comment that approves supplemental registry entries or the ZCode bridge. #11937 approves using ACP for DeepSeek Harness (dsh --profile acp) and does not approve this search-list addition. ZCode has no prior discussion.
Verification
Windows, Node v24.18.0.

Not checked: the full AcpRegistrySupport suite (this machine already fails unrelated path cases), a live ZCode desktop, and screenshots of the registry search results. An earlier DeepSeek probe completed initialize, session/new, and session/close, and advertised no auth methods. Icons are omitted; both agents use the generic ACP glyph.

The ACP Registry adds supplemental DeepSeek Harness and ZCode records. Local commands can use recognized npm Windows shims. Authentication readiness and local ACP setup now account for advertised sign-in methods and proceed to a sign-in step.

Recognizes supported npm Node.js shims and resolves their script and Node executable for local inspection and launch. Tests cover successful resolution and missing Node.js. The documentation distinguishes standard npm launchers from custom batch scripts.

Authentication readiness and sign-in controls account for advertised methods. Local ACP instances use the ACP Registry wizard and proceed to sign-in after saving. Tests and documentation cover the updated flows.
Installed DeepSeek Harness may not appear in search without npm, and Windows shim setup can report ready before Node.js is found. Both are narrow edge cases with a clear fix and low merge risk.

launchLocalExecutable returns either a plain object or an error value.
The function returns a union of a spawn descriptor and an AcpRegistryError that callers must check with instanceof. A missed check at a new call site would silently pass an error object as a spawn descriptor. Return an Effect instead, and use Effect.fn. This also matches the docs/internals/effect-services.md style of typed errors in the error channel.

main returned zero results for both searches. the pr returned one entry each and installed deepseek harness 0.2.2-rc.1 and zcode 0.3.2 through their add buttons.
the real deepseek registry and local-command probes discovered deepseek-v4-flash. both reached the sign-in step, then correctly hid sign-in after the agent advertised no methods. skip completed the wizard. main had closed the local-command wizard immediately.
a real local codex acp bridge advertised chatgpt and api-key methods, and the new sign-in step displayed them. gpt-6.1-sol completed a turn and follow-up through that acp instance. server logs show successful initialize, session/new, and both session/prompt calls. the conversation survived a page reload. the bridge emitted a model-metadata fallback warning alongside both replies.

zcode conversations and successful sign-in: the binary installed, but this vm has no compatible zcode desktop. the real session probe failed with "The ACP agent could not create a test session"; sign-in returned "The provider login command did not finish successfully."
windows npm .cmd launching was covered by existing checks, not a real windows runtime. native ios/android and electron desktop were not exercised. external browser login and credential entry were not completed.
Search can install DeepSeek Harness and the unofficial ZCode ACP bridge
through the existing registry driver. An official entry with the same id
replaces the supplemental record.
Local ACP commands use the same sign-in step. On Windows, a standard npm

Limit the dsh PATH preference to the supplemental record.
If the official Registry publishes deepseek-harness, appendMissingAgents keeps the official record. This ID check still selects a PATH dsh instead of the official distribution. The same check affects prepare and inspect at Lines 1700 and 1814. Restrict the PATH preference to the supplemental record so an official entry uses its declared distribution.

Test the catalog behavior, not only the PATH helper.
These assertions cannot detect whether prepare, inspect, and resolve launch the intended agent. Add a focused catalog test for an installed dsh and an official entry with the same ID. The collision case would catch the PATH-precedence defect above. As per coding guidelines, “Backend behavior changes ship with focused tests.” As per path instructions, request tests when they catch a real regression.

Do not present this bridge as compatible with a current ZCode installation.
The pinned v0.3.2 bridge supports ZCode desktop 3.11.2 and rejects other host versions. ZCode desktop 3.17.2 was released on November 4, 2026. A user with that desktop version can add the search result but cannot complete a working ZCode session. Use a bridge verified for the current desktop version, or state the exact required desktop version before the user adds the agent. (raw.githubusercontent.com)

Remove the node:path import. CI fails on it.
The CI step effect-tsgo tsrs --noEmit fails with TS377057 (effect(nodeBuiltinImport)). It disallows import * as NodePath from "node:path". The build stays red until the import is removed.
absoluteSpawnPath needs NodePath.win32, NodePath.posix and NodePath.resolve. Use the Path.Path service already provided in makeAcpRegistryCatalog for the host-relative logic. Move absoluteSpawnPath inside the catalog so it can use the path service. For the drive-relative Windows case, use path.resolve when the service is the Windows implementation. Alternatively, add a documented lint suppression that states why it is needed. The repository rules require a reason for every suppression.
Note a related risk: NodePath.resolve uses the host process.cwd(). The commit message says the path must be anchored independently of the agent working directory, and that holds here. The Path.Path service must keep the same behavior.
As per coding guidelines, "Dependencies come from the environment (yield* FileSystem.FileSystem), never as parameters to make" and "Does every directive you added that disables a lint, type-checker, or LSP diagnostic say why".

Problem
ACP Registry search cannot install DeepSeek Harness or ZCode. Neither agent is in the official registry index. Discussion #11937 asked for DeepSeek Harness and was closed with the existing ACP path:
dsh --profile acp. A dedicated DSH driver (#14026) is the wrong shape.On Windows, the npm launcher for that CLI is
dsh.cmd. T3 refuses generic batch files, so the installed command cannot start. A typed local ACP command also closed the add dialog instead of offering the same sign-in step as a registry agent.Change
When the official registry URL is loaded, T3 appends two records only if those ids are absent. The cached official JSON is unchanged.
@deepseek-ai/dsh@0.2.2-rc.1and startsdsh --profile acp. Credentials stay in the dsh profile. The earlier live probe advertised no login method, so the sign-in step can be skipped.SHA256SUMS) and startszcode-acp. A compatible ZCode desktop install is still required. This is notzcode-acp-server.Local ACP commands now continue to the existing sign-in step. Until a finished probe reports zero auth methods, an installed local command offers that step. A probe that advertises methods shows sign-in even when the snapshot still says authentication is unavailable.
On Windows, a standard npm Node cmd shim is rewritten to
node.exeplus its script and arguments, withshell: false. Custom batch files stay rejected.These pieces belong together: the registry records are how Add installs the CLIs, the shim is how the Windows npm launcher for
dshactually starts, and the sign-in step is the account flow those installs already use.Scope and approval
This stays on the existing ACP registry driver. It does not add a provider package, agent-id checks in the generic adapter, or a new auth protocol.
There is no maintainer comment that approves supplemental registry entries or the ZCode bridge. #11937 approves using ACP for DeepSeek Harness (
dsh --profile acp) and does not approve this search-list addition. ZCode has no prior discussion.Verification
Windows, Node v24.18.0.
