feat(cli): add DeepSeek Harness (dsh) as an init platform - #547
Conversation
`trellis init --dsh` installs the Trellis workflow into a dsh project: - shared workflow + bundled skills under .agents/skills/, byte-identical to the Codex / Gemini CLI / Pi / Kimi writes into the same root - user-invocable entry skills (trellis-start / trellis-continue / trellis-finish-work) under .dsh/skills/, dsh's own highest-rank project skill root - .dsh/DSH.md operator guide dsh is a class-2 pull-based host: it discovers .agents/skills and .dsh/skills natively and loads skills by name through its skill-loader tool. The default web/headless profiles ship no session-start hook, so hasHooks=false and trellis-start stays a user-invocable skill. dsh has no project-level sub-agent definition surface, so no trellis-implement/check/research agent prompts are written — those phases run inline through the workflow skills.

Thanks for opening this PR. I did a second, implementation-level review against DSH What we learned from a real DSH runThe initial skills-only adapter is a useful baseline, but DSH can preserve more of the Trellis experience than we first assumed:
Current designThe current design has two layers. Trellis adapter
DSH host pluginThe host-side functionality is intentionally kept in a separate plugin rather than embedded in Trellis:
The plugin is now public at: One contribution question is whether upstream is comfortable documenting this as an optional companion. Published branchesThe complete Trellis work is currently based on
The docs and marketplace changes are committed in their own forks. The Trellis root branch intentionally does not record fork-only submodule SHAs; those pointers should move only after the child commits are available from the upstream submodule repositories. VerificationTrellis, in a read-only-source Linux Docker validation as the non-root
Plugin:
Real end-to-end DSH run:
The first diagnostic run also completed successfully, but it exposed the two issues above: inherited Codex identity and foreground-like sleep/poll waiting. The second run verifies both fixes. How would you prefer to proceed?Because this PR targets
Also, should I open the docs and marketplace PRs now, or wait until the desired Trellis base and plugin fallback contract are agreed? I am happy to reorganize the commits or provide focused cherry-picks once the preferred direction is clear. |
I think option |
A dsh session launched from another host inherits that host's identity — a dsh started under Codex still carries CODEX_THREAD_ID. dsh ships no hook, so `task.py` resolves through the shell path with no platform hint and walks _ENV_SESSION_KEYS from the top: CODEX_THREAD_ID matched first and Trellis wrote a foreign `codex_<thread>` pointer for dsh work. Puts dsh first in that table. DSH_SESSION_ID is a name no other vendor sets, so first place cannot mis-claim a non-dsh session. Also registers `dsh` in _KNOWN_PLATFORMS so the pointer prefix resolves back to a platform name in context metadata. Reported by @SajoLuo from a live run against dsh 0.1.0-rc.6 (#547). The regression case pins the ordering, not just the lookup: it sets DSH_SESSION_ID and CODEX_THREAD_ID together with no platform hint and fails with `codex_outer` if the entry ever moves down the table. Also adds dsh to the workflow's inline-execution blocks. dsh has no project-level sub-agent surface, so implement/check run in the main session, but it was in neither the sub-agent nor the inline group — an agent reading workflow.md on dsh found no routing block it belonged to. The marketplace mirror is synced to match. Co-authored-by: SajoLuo <SajoLuo@users.noreply.github.com>

Thanks — option 1 works for me. I’ll keep #547 as the minimal Before opening the beta PR, I’ll finish the remaining integration cleanup: make the workflow capability-aware so Thanks for coordinating this. |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Keep the DSH membership check when relaxing the marker assertion.
The prefix-only checks at Line 816 and Line 1513 do not prove that DeepSeek Harness is present. A future workflow update could remove DSH while both tests still pass. Keep the prefix check for extensibility, and add a marker-scoped assertion for DeepSeek Harness.

Routes DeepSeek Harness through native sub-agent dispatch instead of the inline workflow, as the follow-up to #547 agreed in that thread. - collision-free child-only `trellis-agent-{research,implement,check}` role skills with the pull-based context prelude; the main session never loads them itself - capability-aware synchronization: the optional `dsh-trellis` companion's event-driven `trellis_wait` when present, initial foreground dispatch when absent, never polling or sleeping - `trellis init --dsh` still installs no profile plugin — project-level init does not write to the user's dsh profile - nested-host session identity: managed `DSH_TRELLIS_CONTEXT_ID` first, then `DSH_SHELL=1` plus `DSH_SESSION_ID` resolving through the canonical env table ahead of an inherited `TRELLIS_CONTEXT_ID`, with the generic override keeping its precedence everywhere else - bundled, dogfood and marketplace workflow mirrors byte-identical Companion changes merged first: mindfold-ai/marketplace#13 (cfb2f38), mindfold-ai/docs#31 (59d5b37). Beta docs only; stable stays as shipped in 0.6.15, where dsh runs inline. Verified against a real dsh 0.1.0-rc.6: the `subagent` tool schema matches the dispatch instructions, the plugin-absent foreground path settles end to end, and a managed dsh shell resolves its own session identity rather than an inherited outer one.

Brings 18 commits from main, including 0.6.15, the DSH minimal adapter (#547), and the marker-label routing fix. Beta stays on 0.7.0-beta.3 and keeps its own submodule pointers. Git merged three files cleanly whose *content* was contradictory, so those are the ones worth re-reviewing: - workflow.md: main puts dsh in the inline-execution group (#547 has no sub-agent surface), beta puts it in the class-2 sub-agent group (#548 added one). Both edits applied, leaving dsh in both groups. Resolved to beta's semantics — dsh removed from the inline markers in the template, the dogfood copy and the marketplace mirror. - dsh was registered twice: once by #547 on main and once by #548 on beta, in cli/index.ts, commands/init.ts and configurators/index.ts. Different lines each time, so no conflict was raised; tsc caught it. Deduped, keeping beta's wording. - opencode.test.ts: beta's layered-workflow tests fed the plugin a bare {type,text} part, which #524 on main no longer accepts — insertSyntheticTextPart requires an ordinary part with a persisted identity and now emits the breadcrumb as its own part instead of rewriting the user's text. The tests asserted on parts[0] and silently saw the unmodified prompt. Rewritten against the synthetic-part contract; they still verify the layered resolution they were written for. Declared conflicts resolved to beta for everything dsh-related and for the version files; workflow_phase.py took main's _PLATFORM_MARKER_LABELS table, which subsumes beta's dsh-only alias. Verified on the merged tree rather than assumed: - core 344 passed, cli 1825 passed, lint and tsc clean - all 22 platforms resolve a non-empty routing block - dsh resolves the sub-agent route, not the inline one - built the CLI and ran `init --dsh`: 86 files, with the three trellis-agent-* role skills beta expects - marketplace mirror byte-identical to the bundled template
This repository's own `.trellis/` install had drifted to 0.6.14 while the CLI it ships moved to 0.6.16-sd.1, so the generated platform config committed here no longer matched the templates it is generated from, and 86 of 231 receipt entries disagreed with the files at their paths. Diagnosis: 80 of the 86 were the bug fixed in 5a92d58 — the file on disk was already byte-identical to its template, so `analyzeChanges` classified it `unchanged` and the write-back never touched its entry. One `trellis update` run now repairs all of them. The other 6 were content differences, and they are not one thing: - `.trellis/workflow.md` and the four `platform-map.md` copies were **stale generated artifacts**, not customizations. The template gained a `[workflow-state:task_error]` section, and the platform map gained the DeepSeek Harness row from mindfold-ai#547; the committed copies predate both. Regenerated through `update --create-new` and adopted, so the transforms the real pipeline applies are the ones that produced them. - `.trellis/config.yaml` is genuinely repository-owned — it declares this monorepo's `packages:` block and `default_package: cli`. It is *correct* for it to differ from the template, and it is left alone. Overwriting it would have broken the package configuration, which is what `--force` would have done to it had the other five been fixed that way. Result: 86 mismatched of 231 entries -> 1 of 254, the survivor being config.yaml. The entry for `.opencode/package.json` is retained deliberately; update records it as deleted-by-you so the deletion stays detectable. Verified: `.trellis/scripts` still byte-identical to the templates (`diff -rq` silent), 369 core + 1846 cli tests pass.
