What this PR does

Adds a DeepSeek Harness configurator in the same manual fashion as the other UI-driven clients (like CherryStudioConfigurator). The Manual Configuration snippet renders everything needed to mount Unity MCP in DSH as a configuration-only bundle: the two bundle files (package.json + cordis.patch.yml) and the dsh plugin add / dsh plugin remove commands. After a DSH reload the tools surface as mcp__unityMCP__<tool>. DSH's own plugin manager owns enable/disable and removal from there.

Per review feedback the implementation is trimmed to the manual configurator shape: no process execution, no bundle management code, no tests. The whole diff lands around 220 lines.

Relationship to #1453

This branch started from PR #1453 by @VortDyn and keeps his commits in the history. His investigation of the Cordis patch row shape is what the snippet renders today. After review feedback the implementation settled on the manual shape, so the final diff is much smaller than the earlier iterations here.

Why a bundle instead of the home patch

The snippet targets $DSH_HOME/bundles/<profile>/unity-mcp/ installed via dsh plugin add, rather than editing $DSH_HOME/cordis.patch.yml:

  • The bundle shows up in DSH's plugin manager with a working enable/disable toggle.
  • The home patch is a global layer and can collide with rows from other sources (observed two rows for one serverName on a live install).

Test plan

  • tools/compile-check.sh (the license-free Roslyn gate): win, osx, linux pass.
  • Full EditMode suite: 1562 tests, only the 15 pre-existing ExecuteCodeTests failures that also fail on untouched code.
  • Live end-to-end on Windows against a real DSH install: the rendered bundle installs with dsh plugin add, appears in DSH's plugin manager with the toggle, and a DSH agent session lists the 48 mcp__unityMCP__* tools. Removing the plugin removes the tools.

Summary by CodeRabbit

  • New Features
    • Added DeepSeek Harness support with instructions for manually connecting it to Unity MCP. Setup guidance covers HTTP and stdio connection options.
  • Documentation
    • Added DeepSeek Harness to the recommended terminal clients and expanded the client setup guide with profile-specific setup and removal instructions.

Adds a DeepSeek Harness configurator so "Configure All Detected Clients"
covers DSH the way it already covers Cursor, Codex, Claude Code and Pi.

DeepSeek Harness differs from every other JSON/TOML client here in one way
that had to be handled rather than assumed: `dsh` consumes MCP servers
through its `@deepseek-ai/dsh-mcp-client` plugin, configured as Cordis rows
in a YAML patch layer -- `$DSH_HOME/cordis.patch.yml` (override wins, then
the env var, then `~/.dsh`) -- not a JSON/TOML config file. The package has
no YAML parser, and real patch files may contain features YAML parsers
choke on (`!!js` JS-expression tags, anchors) plus unrelated server rows
that must never be corrupted. All patch-file surgery therefore lives in
`DshConfigHelper`, which manages exactly one marker-fenced block: upsert
replaces only the fenced region, status parses only its known row shape,
and Unregister removes only the fenced region.

Detection is fail-closed in both directions: DSH counts as installed only
once it has run at least once (its home directory exists), so a bare
`~/.dsh` from another tool cannot read as "detected", and a DSH user who
has not configured any MCP server yet is still reported.

Tests cover the block surgery (HTTP/stdio row shapes, round-trip parsing,
idempotent upsert, foreign patches preserved byte-for-byte, register-then-
unregister leaves user content intact) and the configurator contract
(config path, status with and without auto-rewrite).

Docs: capability matrix row, the terminal-client list, and the per-client
DSH section in the configurators guide. Also ignore `.compile-out/`, the
scratch output of tools/compile-check.sh.
Addresses the CodeRabbit review on PR CoplayDev#1453:

- DshConfiguratorTests fed "it''s-a-key" (two literal apostrophes) into
  BuildUnityMcpBlock. Quote doubled them into four, and Unquote returned
  the doubled value, so the assertion against "it''s-a-key" failed. The
  round-trip logic was correct; only the test input was wrong. Pass the
  unescaped value instead.
- Fix the garbled sentence ("may contain features one (e.g.") in the
  DSH section of website/docs/guides/client-configurators.md.
…cs for bundle flow

- RunDshCommand resolves the dsh launcher via DSH_CLI override then PATH+PATHEXT (dsh.cmd/dsh.bat/dsh.exe/dsh) and routes .cmd/.bat shims through cmd.exe /s /c; Process with UseShellExecute=false cannot find dsh.cmd by bare name, so Configure would have failed on every Windows install.

- Configure fails fast when the target DSH profile does not exist (with the available profiles listed), because 'dsh plugin add' silently initializes a missing profile as a bare, unusable one.

- Commit .meta for the new sources per repo convention.

- Docs: describe the native bundle flow (dsh plugin add / remove, profile-scoped) instead of the root home patch.
Matches DSH's own bundle template and the behavior proven in the live end-to-end run: mount failures surface as visible entry activation errors instead of silently degrading.
PathsEqual runs Path.GetFullPath, which throws on the characters package specs contain ('>'), and its catch returns false for identical strings — so the stdio status check could never match a PyPI spec and always reported IncorrectPath (other clients mask this with auto-rewrite). Add PackageSourcesEqual: specs compare as text, path-like sources as normalized paths. Adds the stdio status tests the suite was missing (all previous status tests used HTTP).

📝 Walkthrough

The change adds a manual DeepSeek Harness configurator that generates profile-specific setup bundles for HTTP and stdio transports. Documentation describes the setup, and .gitignore adds two exclusion patterns.

Changes: DeepSeek Harness integration

Layer / File(s) Summary
Configurator lifecycle and discovery
MCPForUnity/Editor/Clients/Configurators/DeepSeekHarnessConfigurator.cs, MCPForUnity/Editor/Clients/Configurators/DeepSeekHarnessConfigurator.cs.meta, website/docs/getting-started/clients.md
The configurator identifies DeepSeek Harness, resolves its home and profile paths, detects installation from the home directory, and reports NotConfigured. It provides manual setup instructions. The getting-started documentation lists DeepSeek Harness as a terminal client.
Bundle generation and transport settings
MCPForUnity/Editor/Clients/Configurators/DeepSeekHarnessConfigurator.cs, website/docs/guides/client-configurators.md
The configurator generates bundle files and profile-specific plugin commands. Its patch row uses HTTP settings, including a conditional API-key header, or stdio settings that require uvx. The guide describes the bundle, transport fields, and plugin commands.

…le bundles, docs

- RunDshCommand drains stdout/stderr concurrently (ReadToEndAsync started before the timed wait). Sequential blocking reads could deadlock when the child filled the other pipe, and a hung dsh would freeze the editor because the timeout sat after the reads.

- Bundle paths are profile-qualified (\/bundles/<profile>/unity-mcp/): dsh plugin add symlinks the bundle directory into the profile, so a shared path let one profile's Unregister dangle another's link. Profile names are validated against path traversal. Regression tests cover cross-profile isolation.

- Docs: Auto-config cell is 'no (manual Configure)' per SupportsAutoConfigure => false; bundle paths updated.

- Docstrings: one-line summaries for the 44 diff functions that lacked them.

@coderabbitai review — thanks for the sharp review. All three findings were valid; fixed in the latest push.

1. RunDshCommand sequential-read deadlock (Major) — fixed. Classic .NET hazard and worse than described: since Configure() runs on the editor main thread, a hung dsh would have frozen the whole editor because the timed WaitForExit sat after the blocking reads. Now both pipes are drained with ReadToEndAsync() started before the timed wait, results collected after exit; timeout kills the process and returns immediately.

2. Shared bundle path across profiles (Major) — fixed. Confirmed the symlink behavior on a live DSH install (dependencies showed link:...), so the dangling-link scenario was real. Bundle paths are now profile-qualified ($DSH_HOME/bundles/<profile>/unity-mcp/) and profile names are validated (rejects .., separators, invalid filename chars). Added Bundles_AreIsolatedPerProfile and Unregister_OnlyRemovesTargetProfileBundle regression tests covering exactly the cross-profile delete scenario. Docs updated with the rationale. Note: no migration code — the bundle path never shipped in a release, so only test installs used the old location.

3. Auto-config cell (Minor) — fixed. The cell now reads no (manual Configure), matching SupportsAutoConfigure => false.

Docstring coverage — added one-line <summary> docs to the 44 functions in the diff that lacked them (mostly test methods), including BuildConfigPath, GetManualSnippet, BuildBlock, IsCmdShim, QuoteArg, and LooksLikeFilePath.

Verification pushed alongside: DSH EditMode suites green (40 tests), tools/compile-check.sh green for win/osx/linux, and the cross-profile behavior additionally verified against a live DSH install (bundle appears in the plugin manager UI with a working enable toggle; unregister removes exactly one profile's registration).

@sobhanb-eth Thanks for the fixes and the technical details. I’ll review the latest changes, including the process timeout handling, profile isolation, documentation, and regression tests.

Thanks for clarifying the editor-main-thread constraint and confirming DSH’s bundle-link behavior.

Learning: In CoplayDev/unity-mcp, DeepSeekHarnessConfigurator.Configure() runs on the Unity editor main thread. RunDshCommand must drain stdout and stderr concurrently and enforce a timeout to prevent a hung DSH process from freezing the editor.

Learning: In CoplayDev/unity-mcp PR #1471, live DeepSeek Harness verification showed bundle dependencies registered as link: paths. DSH registrations therefore depend on the bundle directory remaining present. Bundle directories must be profile-scoped so unregistering one profile does not leave another profile with a dangling link.

@coderabbitai review — round 2 findings both valid; fixed in the latest push.

1. Unregister deletes the bundle when dsh plugin remove fails (Major) — fixed. The removal result is now checked: on a nonzero exit the bundle is kept (the profile still links the directory — deleting it would dangle the symlink exactly as described) and Unregister throws with the exact manual command so the user can retry. When the profile does not list the bundle at all, the leftover files are deleted without invoking the CLI (nothing links them, so no dangling state is possible). Regression tests: Unregister_RemovalFailure_KeepsBundleAndThrows, Unregister_Unregistered_DeletesFilesWithoutRemove.

2. cmd.exe metacharacters in profile names (Major) — fixed. Verified the cmd semantics empirically before choosing the fix: &, |, ^ are literal inside double quotes (so quoting is sufficient for them), but %VAR% expands even inside quotes and %% is not reduced on a cmd /c command line — so percent cannot be escaped there. The fix is therefore: (a) every argument is now double-quoted with standard CommandLineToArgvW escaping (backslash-before-quote doubling), which keeps legitimate names like R&D and home paths containing & working; (b) profile names reject " and % outright (GetBundleDir validation). Regression coverage: the cmd-shim test now round-trips R&D and C:\bundle dir through a real cmd.exe invocation and asserts they arrive as data; GetBundleDir_RejectsUnsafeProfileNames covers %/" rejection and asserts R&D is accepted.

Docstrings updated for the reworked methods. Verification: DSH EditMode suites green (42 tests), tools/compile-check.sh green for win/osx/linux.

@sobhanb-eth Thanks for the fixes and the detailed verification report. I’ll review the latest push, focusing on:

  • Bundle preservation when dsh plugin remove fails.
  • Cleanup of unregistered bundle files without invoking DSH.
  • Windows argument quoting and profile-name validation.
  • Regression coverage for both findings.

DSH's plugin-manager toggle keeps the dependency installed while dropping the
entry from dsh.profile.bundles. Unregister skipped dsh plugin remove in that
state and deleted the directory the dependency links. Unregister now runs the
CLI when the profile declares the bundle in either place and only skips it for
bare leftover files. Status checks keep the strict enabled look: a disabled
bundle mounts no tools.

Regression test: Unregister_DisabledButInstalled_StillRunsRemove.

@coderabbitai review — round 3 finding valid; fixed in the latest push.

Disabled-but-installed bundle removal (Major) — fixed. You're right about the toggle semantics: enabled (dsh.profile.bundles) and installed (dependencies) are separate states, so a disabled bundle kept its dependency while my round-2 gate skipped dsh plugin remove and deleted the directory the dependency links.

Unregister now uses ProfileDeclaresBundle, which treats the bundle as present when it appears in either dsh.profile.bundles (enabled) or dependencies (installed, possibly disabled) — dsh plugin remove runs in both cases, and the CLI is only skipped when neither declares it (bare leftover files, safe to delete). Status checks intentionally keep the strict dsh.profile.bundles look: a disabled bundle mounts no tools, so the Setup window shows Not Configured and clicking Configure re-enables it via dsh plugin add.

Regression test added as requested: Unregister_DisabledButInstalled_StillRunsRemove simulates the toggle (dependency present, bundles entry removed) and asserts remove still runs and the bundle is cleaned up.

Verification: DSH EditMode suites green (43 tests), tools/compile-check.sh green for win/osx/linux.

Quote the profile in manual DSH commands.

When Configure fails for an accepted profile such as R&D, the error tells the user to copy dsh plugin --profile R&D add .... In Windows cmd.exe, & separates commands, so the copied retry can use the wrong profile and execute an unintended command. Quote the displayed arguments separately from the runner's argument array. Apply the same correction to the Unregister retry and manual snippet commands.

@sobhanb-eth Thanks for the fix and the verification report. I’ll review the latest push, focusing on:

  • ProfileDeclaresBundle checking both enabled and installed registrations.
  • Unregister removing disabled-but-installed bundles through the CLI.
  • Status checks continuing to require an enabled bundle.
  • Unregister_DisabledButInstalled_StillRunsRemove regression coverage.

This matches the enabled-versus-installed distinction in the existing learning.

Learning: In CoplayDev/unity-mcp, DeepSeek Harness tracks enabled bundles in dsh.profile.bundles and installed bundles in dependencies. A disabled bundle can retain a dependency linked to its bundle directory. DeepSeekHarnessConfigurator.Unregister() uses ProfileDeclaresBundle to check both locations and must run dsh plugin remove when either declares the bundle. It skips the CLI only when neither declares the bundle. Status checks intentionally require the enabled entry in dsh.profile.bundles because disabled bundles mount no tools; Configure re-enables the bundle through dsh plugin add.

Is it possible to shrink this and let it work as a manual configuration like the CherryStudioConfigurator we had? Also no test is needed for such project with 900~ lines. I would love to add Deepseek Harness, but the current size seems like a maintenance mess.

Hey, fair point. It grew way past what I expected and I get the maintenance concern.

Here's what's in there right now. The configurator writes a small bundle into the dsh home folder and installs it with dsh plugin add. There's a Configure button and an Unregister button, and the window shows whether it's set up and whether the config still matches the transport you picked. I tested the whole thing by hand. The bundle shows up in the DSH plugin manager with the working toggle and the tools show up as mcp__unityMCP__*, so the native plugin side works.

If we go the CherryStudio route, we lose the two buttons and the status dot. You'd copy two commands from the manual snippet and paste them into a terminal instead. What stays the same is everything at runtime. Same bundle, same plugin manager UI with the enable toggle, same tools. DSH already owns the install and remove lifecycle anyway, so the buttons were kind of a second copy of that living in Unity.

That gets us to around 200 lines total and all the process execution code goes away. That's where every bug we found lived, so cutting it removes the whole problem area.

There's one middle ground I'm curious about. The status check could stay read only. It would just look at the profile file and tell you whether the bundle is installed. No writes, no running commands, just a truthful status in the window. Around 20 lines.

What's your preference? Fully manual like CherryStudio with no status at all, or is the read only status fine? And do you want the tests gone completely or would two or three tiny ones for the snippet be okay? I'd rather match what the repo prefers before I cut it down.

Lets trim it down to 200 lines if thats possible, also lets get the tests gone, keeping it under similar fashion with our other configurators.

Per review direction, keep it in the same fashion as the other manual
configurators and under roughly 200 lines, with the tests gone. The class
now only renders the manual snippet (the two bundle files plus the quoted
dsh plugin add and remove commands). DSH's plugin manager owns the install,
enable/disable, and removal lifecycle from there.

This drops the helper and test files from the earlier iterations on this
branch, including the process execution and bundle management code.

Done, trimmed it down like you asked.

The configurator is 187 lines now and the whole diff against beta lands around 220 including docs and the meta file. Tests are gone too.

It works the same way CherryStudio does now. The class just renders the snippet, which carries the two bundle files and the quoted dsh plugin add and remove commands. Install, enable and disable, removal, all of that lives in DSH's plugin manager where it belongs. The window shows the copy and paste text and that is it.

So the trade is two terminal commands instead of a button. Same bundle either way, same plugin in DSH's plugin manager with the toggle, same tools after a restart.

Compile check is green again on all three platforms. Let me know if you want it even smaller or if this shape works.

deepseek-harness dsh CLI plugin --profile desktop reserved Electron profile README

💡 Result:

The **official README reserves `desktop` for Electron**—it isn’t a normal profile you can boot or manage with an npm-installed `dsh` CLI. The CLI README says it rejects boot, config-dump, and plugin-management requests for that profile. ([github.com](https://github.com/deepseek-ai/deepseek-harness/blob/master/apps/cli/README.md))

For the official Desktop app, launch it once to initialize its profile, fully quit, then use the **Desktop-installed** `dsh` command to manage plugins:

```sh
dsh plugin --profile desktop add <package>
```

Reopen Desktop to activate the change. The README says the npm-installed CLI cannot mutate the Electron-owned profile. ([github.com](https://github.com/deepseek-ai/deepseek-harness/blob/master/apps/desktop/README.md))

If you’re trying to create an ordinary CLI profile, choose another name; `desktop` is specifically reserved for Electron. ([github.com](https://github.com/deepseek-ai/deepseek-harness/blob/master/apps/cli/README.md))

official DeepSeek Harness CLI README DSH_PROFILE desktop Electron plugin management profile

💡 Result:

The official repository describes **DSH profiles** as named configurations under `$DSH_HOME/profiles`; plugins are installed into a profile and listed in its ordered `dsh.profile.bundles` manifest. The CLI manages them with `dsh plugin --profile <name> add|remove …`. ([github.com](https://github.com/deepseek-ai/deepseek-harness/blob/master/docs/cli-help.md))

For **Electron Desktop**, the reserved `desktop` profile is owned exclusively by the app. To manage its plugins from a terminal:

1. Launch Desktop once to initialize the profile, then fully quit it.
2. Use Desktop’s bundled `dsh` command: `dsh plugin --profile desktop add <package>` (or `list` / `remove`).
3. Reopen Desktop to apply changes.

The README says the regular CLI cannot boot or modify this Desktop-owned profile; use the Desktop-installed command, not an npm-installed `dsh`. Desktop’s in-app plugin management is through the app’s Plugins page—not a separate Electron plugin-management IPC. ([github.com](https://github.com/deepseek-ai/deepseek-harness/blob/master/apps/desktop/README.md))

**`DSH_PROFILE` isn’t established as the profile-selection variable** in these README/help references; they document the `--profile` flag instead. The sources also don’t establish whether another version supports `DSH_PROFILE`. ([github.com](https://github.com/deepseek-ai/deepseek-harness/blob/master/docs/cli-help.md))

Do not use desktop as the ordinary CLI default.

When DSH_PROFILE is unset, ProfileName() selects desktop. The generated dsh plugin --profile desktop add ... command then targets the Electron-owned profile, which the regular npm-installed DSH CLI cannot modify.

The current default appears intentional for Desktop, but the snippet must either require a documented CLI profile or explain that desktop requires the Desktop-installed dsh command after Desktop is closed.

The desktop profile is Electron-owned. Verified against the Desktop-installed
dsh (0.2.1-rc.2): dsh plugin add/remove/ls on the desktop profile work (the
documented Desktop flow), while --dump-config and boot are rejected with
"managed exclusively by the Electron application". The snippet and steps now
say to quit DeepSeek Harness before running the commands and to pick another
profile name when using a standalone npm dsh.

Good catch on the reserved profile, but the plugin-management half of the finding doesn't hold for the setup this targets. I verified against the Desktop-installed dsh (it auto-updated from 0.2.0-rc.2 to 0.2.1-rc.2 since our live test, which is where the new guard appeared):

command on desktop result
dsh --profile desktop --dump-config rejected, exit 1: error: profile "desktop" is managed exclusively by the Electron application
dsh plugin --profile desktop add --help forwarded to pnpm, prints pnpm add usage
dsh plugin --profile desktop ls --depth 0 works: └── @local/unity-mcp-dsh@link:../../bundles/unity-mcp

So the CLI only guards boot/config-dump. The plugin subcommand forwards to pnpm in the profile directory even for desktop, which matches the documented Desktop flow your own research quoted ("use the Desktop-installed dsh command to manage plugins: dsh plugin --profile desktop add <package>"). The rejection applies to the npm-installed standalone CLI, not the Desktop one our users resolve from PATH.

That said, two parts of the finding were right and worth 3 comment lines:

  • The documented flow runs the plugin commands with Desktop closed, which the snippet never said.
  • A standalone npm dsh cannot manage desktop, so the snippet now tells those users to pick another profile.

Fixed accordingly: the snippet header and the install step now say quit DeepSeek Harness first, reopen after, and use another profile name with a standalone dsh. No machinery added. Compile check green for win/osx/linux.
