feat(provider-opencode-go): add OpenCode Go Chat Completions provider worker - #690
Merged
Merged
Conversation
OpenCode Go Chat Completions provider behind llm-router. Implements the provider protocol: stream (SSE chunks to AssistantMessageEvent frames), abort, refresh_models (live GET /v1/models enriched with models.dev metadata: context window, reasoning efforts, tool/structured-output capability), and re-declaration on router::ready. Chat Completions wire format only, max_completion_tokens, strict json_schema structured output, reasoning_effort low/medium/high for deepseek-/kimi-k2.7- families. Wired into create-tag/release workflows and the harness worker deps.
README to the provider family structure (Behavior/Tests/Running), manifest tags+description to the canonical form, release wiring in alpha-release.yml and discover_changed_workers.py, llm-router README reference note.
Upstream MOT-4335 rewrote all provider identity prompts to teach the live
surface (register_trigger, harness::spawn, orchestrator: true) and stripped
orchestration-process doctrine. The fork-PR merge with the new main runs the
harness prompts sweep over every shipped prompt, which failed on our pre-
rewrite copy ("delegation is one-way" etc.). Absorb the rewritten prompt,
update the register.rs identity assertions, and apply the iii-state -> state
rename.

Inline comments:
In `@provider-opencode-go/iii-permissions.yaml`:
- Around line 7-9: Add !provider::opencode_go::abort to the deny list in
iii-permissions.yaml alongside the existing provider::opencode_go entries,
preventing agents from invoking the provider-owned abort operation.
In `@provider-opencode-go/src/curated.rs`:
- Around line 219-224: Update the OpenCode Go model metadata and the `Some(m) =>
Model` construction in the curation flow to source `max_output_tokens` from each
known model’s `ModelMeta`; retain 4096 only as the fallback for unknown model
IDs. Ensure the curated `Model.max_output_tokens` reflects the catalog value
used by routing and downstream configuration.
In `@provider-opencode-go/src/discovery.rs`:
- Around line 21-27: Update models_url to derive the models endpoint only from
the configured api_url origin, returning no URL when the path does not end with
/chat/completions instead of falling back to opencode.ai. Adjust
fetch_live_models/refresh_models to skip discovery on that None result while
preserving the existing models slice, and update the related test to verify the
configured origin is retained.
In `@provider-opencode-go/src/main.rs`:
- Line 22: Update the `#[arg]` configuration for the `--url` option in `main.rs`
to use the documented `III_WS_URL` environment variable instead of `III_URL`,
preserving the existing default WebSocket URL.
In `@provider-opencode-go/src/reasoning.rs`:
- Around line 30-52: Update level_str and reasoning_effort_for so each
ThinkingLevel maps to an ordered list of accepted effort aliases, with Minimal
preferring "minimal" then "none"; return the first alias contained in
supported_efforts(model), preserving None when no alias is supported. Add
coverage verifying Minimal returns Some("none") for gpt-5.6-luna and None for
grok-4.5.
In `@provider-opencode-go/src/register.rs`:
- Around line 167-172: Handle the Result returned by register_trigger in
register_provider for the router::ready trigger instead of discarding it with
let _. Log registration failures or propagate the error through
register_provider, ensuring failures remain visible and the existing successful
registration behavior is preserved.
In `@provider-opencode-go/src/sse.rs`:
- Around line 252-257: In the tool-call handling loop around
`state.function_calls` in the SSE delta processing, reject entries whose parsed
`index` exceeds a small fixed bound before the capacity-growing `while` loop.
Skip those oversized tool-call entries and preserve existing behavior for valid
indices.
- Around line 235-251: Update ProviderOpencodeGo’s streaming path so thinking
support is consistent: if the Chat Completions stream provides
delta.reasoning_content, handle it in handle_chunk by tracking state.thinking
and emitting the appropriate thinking events, adding an OpenBlock::Thinking
variant as needed; otherwise remove the unused thinking state/branch and narrow
supports_thinking in the curated metadata.
In `@README.md`:
- Around line 71-73: Repair the Markdown table entries for provider-openai and
provider-opencode-go so each is a complete three-column row with properly placed
pipe delimiters. Keep the existing descriptions intact, ensuring the
provider-openai description remains on its own row and the provider-opencode-go
row remains separate.

Yes, I'll take care of them |
Resolve conflicts from main's release-architecture rework (Release Control workflow_dispatch inputs replaced per-worker lists): - drop PR edits to alpha-release.yml (deleted on main), create-tag.yml, release.yml, discover_changed_workers.py (E2E_WORKERS removed on main) - README.md: keep main's new provider rows; insert provider-opencode-go row between provider-openai and provider-openrouter - harness/iii.worker.yaml: keep main's shell ^0.11.0 / scrapling ^0.2.7 pins, add provider-opencode-go ^1.0.0 dependency Verification: cargo check --all-targets clean; 68 tests pass (58 lib + 2 bin + 4 schema + 4 integration) against engine 0.22.0 and merged llm-router 1.4.3.

The stream trigger type the console's live views subscribe through was missing; add iii-stream to the harness engine stack (matches the integration/e2e stack config pattern).

What
New Rust worker
provider-opencode-go: an LLM provider worker behindllm-routerspeaking the OpenCode Go API — Chat Completions(
https://opencode.ai/zen/go/v1/chat/completions), SSE streaming, live modeldiscovery, auth/error taxonomy, reasoning-effort mapping, tool calling, and
structured output. Registers
provider::opencode_go::stream/refresh_models/
abortwith the router, binds identity via registration token (state scopeprovider-opencode-go), and readsOPENCODE_GO_API_KEYas credential.Why
The stack has no way to route chat completions to an OpenCode Go subscription.
The OpenCode Go API is Chat Completions compatible, so the existing
provider-openaiworker ports directly — same protocol, same relay/pumpscaffold, same error taxonomy, with the OpenAI-only surfaces (embeddings,
Responses API) dropped as dead code.
How it works
router::provider::resolve(config slice →
OPENCODE_GO_API_KEYenv on the router → none); sent asAuthorization: Bearer.AssistantMessageEventframesinto a router-owned channel;
ping≥ every 30s of silence; a failed channelwrite (
router::abort/ caller gone) drops the SSE receiver and aborts thein-flight HTTP request. Stream-path
tracing::debugfor provider-sideobservability.
GET /v1/modelssupplies bare ids; each isenriched from a hardcoded curated metadata table (
src/curated.rs) preparedfrom models.dev (2026-08-03) — context window, reasoning support/effort
levels, tool-call and structured-output capability for the maintainer's
curated model set (24 models.dev entries +
hy3-preview). Ids outside thetable keep conservative defaults (128K, no thinking, tools on) — same
pattern as provider-openai's
curated.rs.thinking_levelmaps to the upstreamreasoning_effortonlywhen the model's curated effort list accepts the level (e.g.
grok-4.5accepts

provider-openai: mechanical renames only in most files; theOpenAI-only surface (ApiMode, embeddings, Responses-API event handlers and
thinking deltas, curated reasoning-fallback ladder, luna guard) is dropped —
OpenCode Go has no such surface.
opencode/worker —different role (CLI wrapper vs provider), no overlap; both install side by
side.
hy3-previewis listed by the liveGET /v1/modelsbut the chat endpointcurrently returns
ModelNotFound— an upstream inconsistency; the curatedrow keeps conservative defaults and the provider surfaces the upstream error
cleanly.
