Internal LLM-shaped work — model classification, free-form prompt elaboration, webhook CI summarization, execution summary — either shells out to the `gemini` CLI (`internal/executor/classifier.go:60`) or sits in `internal/api/elaborate.go` doing the same. That's expensive in latency and dollars for what are essentially helper completions, and there's no path to keep "internal" reasoning private/local. + +This change adds a local OSS model backend (any OpenAI-compatible HTTP server: Ollama, vLLM, LM Studio, llama.cpp server) as a first-class third Runner alongside Claude and Gemini. The unified harness model wins over a separate "internal LLM service" because it preserves a single `Runner` abstraction, single `executions` table, and one set of pool semantics (rate-limit handling, observability, WebSocket events) for any task whose `agent.type == "local"`. + +Outcome: a `LocalRunner` for user-facing tasks, plus a lower-level `LocalLLMClient` that internal helpers call directly without paying Pool/Execution overhead. First migration target is the classifier (sub-second, high-volume, lowest blast radius). Elaboration, webhook summarization, and execution summary follow in subsequent passes using the same client. + +## Architectural decision: two layers, one backend + +`LocalRunner implements Runner` is the user-visible contract. But the classifier runs *inside* `Pool.execute()` (at `internal/executor/executor.go:437`), so submitting recursively to `Pool` would deadlock against `workCh`'s slot accounting and pollute the `executions` table with sub-second rows for every classification. + +Resolution: introduce a `LocalLLMClient` (HTTP, no Pool, no DB) as the workhorse. `LocalRunner` is a thin adapter over it for full Pool-managed executions. Internal callers — classifier now, elaborate/webhook/summary later — call `LocalLLMClient` directly. Two code paths to local, but path lengths are wildly unequal (the runner is ~150 lines of glue) and they share one HTTP round-tripper. + +Capabilities (e.g. "this runner can edit code, that one can't") are deferred. `LocalRunner` simply leaves `SandboxDir` empty; the Pool already tolerates that. Revisit only when a third non-coding runner appears. + +## End state + +- **`internal/llm`** (new package) — `LocalLLMClient` with `Chat` and `ChatStream` over OpenAI-compat `/chat/completions`. Handles retries via the existing backoff helper, JSON mode, SSE streaming, optional bearer token. +- **`internal/executor/local.go`** (new) — `LocalRunner` implements `Runner`. Streams response deltas into the same stream-json envelope Claude uses (`{"type":"assistant","message":{"content":[{"type":"text","text":"..."}]}}`) so existing parsers (`internal/executor/summary.go:13`, `internal/task/changestats.go`) keep working unchanged. +- **`Classifier`** (`internal/executor/classifier.go`) — now holds a `*llm.Client`. When set, classification goes through it with `response_format: json_object`; markdown-fence cleanup is skipped on this path. Gemini-CLI path stays as a fallback when `[local_model]` config is empty. +- **Storage** — `executions.tokens_in` and `tokens_out` added (additive `ALTER`, schema pattern at `internal/storage/db.go:78-89`). `cost_usd` stays 0 for local. `session_id`/`sandbox_dir` remain nullable; `LocalRunner` simply doesn't populate them. +- **`AgentConfig`** — adds `Temperature *float64` (pointer so 0 means "unset") and `MaxTokens int` at `internal/task/task.go:30`. Existing Claude-shaped fields (`PermissionMode`, `AllowedTools`, etc.) are silently ignored by `LocalRunner`. +- **Config** — new `[local_model]` TOML section in `internal/config/config.go:18`: `endpoint`, `model`, `timeout_seconds`, `default_temperature`, `api_key`. If `endpoint` is empty, the runner is not registered and the classifier falls back to Gemini-CLI. +- **Routing** — `executor.go:428`'s hardcoded `t.Agent.Type == "claude" || == "gemini"` widens to include `"local"` (or, cleaner, becomes `t.Agent.Type != ""`). +- **Wiring** — `cmd/claudomator/main.go`, `internal/cli/serve.go:60-78`, and `internal/cli/run.go:75-90` build the `*llm.Client` from config and register both `runners["local"]` and `pool.Classifier.LLM`. +- **GeminiRunner** (`internal/executor/gemini.go`) — kept and finished alongside as a separate concern. The shared backoff helper move (below) and the `LogPather` interface it already implements (`gemini.go:26`) are unaffected. Real subprocess invocation replacing the simulated stdout block at `gemini.go:107-116` is a follow-up commit, not gated by this change. + +Shared utility move: `runWithBackoff` currently lives at `internal/executor/ratelimit.go:60`. Move it to a new tiny `internal/retry` package so both `internal/executor` and `internal/llm` use it. One-line change at the existing call site in `claude.go`. + +## Migration phases + +**Phase 1 — this pass. Classifier swap.** All the `internal/llm` + `internal/executor/local.go` + `Classifier` work above. Gated by config: if `[local_model].endpoint` is unset, behavior is unchanged. Net new files; no breaking changes to existing runners. + +**Phase 2 — task elaboration.** `internal/api/elaborate.go:208-275` currently has Claude and Gemini paths. Add `elaborateWithLocal`; new try-order is local → claude → gemini, controlled by a `prefer_local_for_elaborate` config flag. `Server` (`internal/api/server.go:76`) gains an `llm *llm.Client` field passed via `NewServer`. + +**Phase 3 — webhook CI summarization.** `createCIFailureTask` at `internal/api/webhook.go:154` builds task instructions from a hardcoded template. Add an optional summarization step calling `s.llm.Chat` over the fetched workflow logs to produce a tighter `instructions` body. Pure additive. + +**Phase 4 — execution summary.** `extractSummary` (`internal/executor/summary.go:13`) is text-pattern based. Add `summarizeExecution(ctx, *llm.Client, stdoutPath) string` that synthesizes a summary when no `## Summary` section exists. Hook lives in `Pool.handleRunResult` at `executor.go:347-355`; pass `*llm.Client` through `Pool` construction. + +## Critical files + +**New:** +- `internal/llm/client.go` — `Client`, `Chat`, `ChatStream`, request/response types +- `internal/llm/client_test.go` — `httptest`-driven coverage +- `internal/executor/local.go` — `LocalRunner` +- `internal/executor/local_test.go` — runner tests with stub `*llm.Client` +- `internal/retry/backoff.go` — relocated `runWithBackoff` + +**Modified:** +- `internal/executor/classifier.go` — add `LLM *llm.Client` field, route through it when set, keep Gemini fallback path +- `internal/executor/classifier_test.go` — add httptest-backed test +- `internal/executor/executor.go:428` — broaden `skipClassification` predicate +- `internal/executor/ratelimit.go` — remove `runWithBackoff` (moved); update import in `claude.go` +- `internal/task/task.go:30-43` — add `Temperature`, `MaxTokens` to `AgentConfig` +- `internal/config/config.go:18-52` — add `LocalModel` struct + field to `Config` +- `internal/storage/db.go:78-89` — two additive `ALTER` migrations; add `TokensIn`/`TokensOut` to `Execution` struct; update SELECT/INSERT/UPDATE SQL in same file +- `internal/cli/serve.go:60-78`, `internal/cli/run.go:75-90`, `cmd/claudomator/main.go` — build client, register runner, wire classifier + +## Reuse, not reinvention + +- `runWithBackoff` (`internal/executor/ratelimit.go:60`) → relocated and reused by `LocalLLMClient` +- `isRateLimitError`/`isQuotaExhausted` (`executor.go:271-283`) → emit compatible error strings from `LocalLLMClient` so Pool's existing rate-limit handling treats local 429/503 identically +- Stream-json envelope from `claude.go:600` parsing → `LocalRunner` writes the same envelope so `extractSummary` and `ParseChangestatFromFile` work unchanged +- Existing nullable `session_id`/`sandbox_dir` columns → no schema rework needed for non-coding runners +- `LogPather` interface (`executor.go:38`) → `LocalRunner` implements it for log path pre-population, just like `GeminiRunner` already does + +## Verification + +**Unit tests:** +- `internal/llm/client_test.go`: httptest server returns canned chat-completion JSON; assert `Chat` returns parsed `Content`, prompt/output tokens, model.

Third: HTTP 429 with `Retry-After: 1` → assert one retry then success. +- `internal/executor/classifier_test.go`: httptest backend returning JSON-mode response → assert `Classification` parsed correctly. Existing mock-binary test stays for the Gemini fallback path. +- `internal/executor/local_test.go`: stub `*llm.Client` returning fixed text → `Run` writes correct stream-json envelope to `stdout.log`; verify `extractSummary` finds `## Summary` from that envelope. +- `go test -race ./...` passes (Pool reentrancy is the risk this design avoids; race detector would catch slips). + +**Manual end-to-end against Ollama:** +1. `ollama pull llama3.1:8b && ollama serve` +2.

Submit a task with `agent.type = "local"`, `instructions = "Summarize: 2+2"`. Expect `READY`/`COMPLETED` execution, populated `stdout.log` with stream-json text deltas, `cost_usd = 0`, non-zero `tokens_out` in the `executions` row. +5. Stop Ollama → submit another task → classifier should fall back to `gemini` invocation (or fail with a rate-limit-style error if no Gemini binary present). Confirms the `endpoint == ""` and runtime-failure fallback paths both work. + +**Build sanity:** `go build ./...` and `go test -race ./...` (CGo / `gcc` required per CLAUDE.md). + +--- + +# Phase 1 — Focused Plan + +This is the only phase we execute in this pass.

This is the durable record that lives with the codebase. Phase 2/3/4 focused plans will be appended to the same file when started. + +2. **Create branch.** `git checkout -b claude/local-oss-model-agents-MEBqj` (already designated; create if it doesn't exist). + +3. **`internal/retry/backoff.go`** — relocate `runWithBackoff` from `internal/executor/ratelimit.go:60`. Update the existing call site in `internal/executor/claude.go` to import from the new path. Keep all signature and behavior unchanged. Run `go build ./...` and `go test ./internal/executor/...` to confirm zero behavioral change. + +4. **`internal/llm/client.go`** — implement the package. Types from the design: + - `Client{Endpoint, Model, HTTPClient, APIKey, Logger}` + - `ChatRequest{Model, Messages, Temperature, MaxTokens, ResponseJSON, Stream}` + - `Message{Role, Content}` + - `ChatResponse{Content, PromptTokens, OutputTokens, Model, FinishReason}` + - `Chat(ctx, req)` — POSTs `/chat/completions`, wraps in `retry.RunWithBackoff`, maps 429/503 to `isRateLimitError`-compatible error strings + - `ChatStream(ctx, req, onDelta)` — same endpoint with `stream: true`, parses SSE `data:` lines, calls `onDelta(text)` per chunk, terminates on `data: [DONE]`, aggregates final response + +5. **`internal/llm/client_test.go`** — three tests: + - Canned chat-completion JSON → assert `Chat` returns parsed `Content`, prompt/output tokens, model + - SSE stream of `data:` lines terminated by `data: [DONE]` → assert `onDelta` called per chunk, final `ChatResponse` aggregated + - HTTP 429 with `Retry-After: 1` → assert one retry then success + +6. **`internal/storage/db.go:78-89`** — append two `ALTER TABLE executions ADD COLUMN` migrations for `tokens_in INTEGER` and `tokens_out INTEGER`. Add `TokensIn`, `TokensOut int64` to `Execution` struct. Update SELECT, INSERT, UPDATE SQL in the same file. Existing `isColumnExistsError` swallows duplicate-column errors so re-running is safe. + +7. **`internal/task/task.go:30-43`** — add `Temperature *float64` and `MaxTokens int` to `AgentConfig` with appropriate yaml/json tags. Pointer for Temperature so 0 means "unset, use server default." + +8. **`internal/config/config.go:18-52`** — add `LocalModel` struct (`Endpoint`, `Model`, `TimeoutSeconds`, `DefaultTemperature`, `APIKey`) and `LocalModel LocalModel` field on `Config`. `Default()` leaves `Endpoint` empty. + +9. **`internal/executor/local.go`** — `LocalRunner` struct with `Client *llm.Client`, `Logger`, `LogDir`. Implement `Run(ctx, *task.Task, *storage.Execution) error`: + - Build messages from `t.Agent.SystemPromptAppend` + `Instructions` + - Call `Client.ChatStream` with `onDelta` writing `{"type":"assistant","message":{"content":[{"type":"text","text":"<delta>"}]}}` lines to `e.StdoutPath` + - On completion, write a final `{"type":"result", ...}` line so existing parsers see a recognizable terminator + - Set `e.TokensIn`, `e.TokensOut`, `e.CostUSD = 0`, `e.Status = "READY"` + - Implement `LogPather` so log paths pre-populate consistently with other runners + +10. **`internal/executor/local_test.go`** — runner tests with a stub `*llm.Client` (use a small interface or test-injected `HTTPClient`): + - Stub returns fixed text containing a `## Summary` section + - Assert `Run` writes correct stream-json envelope to `stdout.log` + - Assert `extractSummary(stdoutPath)` (from `internal/executor/summary.go`) finds the summary + - Assert `e.TokensOut > 0` and `e.CostUSD == 0` + +11. **`internal/executor/classifier.go`** — add `LLM *llm.Client` field on `Classifier`. In `Classify`, when `c.LLM != nil`, use `LLM.Chat` with `ResponseJSON: true`, skip the markdown-fence cleanup. When nil, fall through to the existing Gemini-CLI subprocess path. Existing prompt template stays (already lists Claude+Gemini models, which is what the classifier still picks among). + +12. **`internal/executor/classifier_test.go`** — add httptest-backed test for the LLM path. Existing mock-binary test (if present) stays for the Gemini fallback path. + +13. **`internal/executor/executor.go:428`** — change `skipClassification := t.Agent.Type == "claude" || t.Agent.Type == "gemini"` to `skipClassification := t.Agent.Type != ""`. This generalizes correctly: any explicitly-set agent type skips selection; unset still goes through `pickAgent` + `Classifier`. + +14. **Wire registration** in three files: + - `cmd/claudomator/main.go` — build `*llm.Client` from `cfg.LocalModel` if `Endpoint != ""`, pass to pool construction + - `internal/cli/serve.go:60-78` — register `runners["local"] = &executor.LocalRunner{...}`, set `pool.Classifier = &executor.Classifier{LLM: localClient, GeminiBinaryPath: cfg.GeminiBinaryPath}` + - `internal/cli/run.go:75-90` — same pattern + +15. **`go test -race ./...`** — full suite passes. The race detector is the safety net for the reentrancy-avoidance design. + +16. **Manual smoke test against Ollama** — five steps documented in the Verification section above. Confirm the fallback path by stopping Ollama mid-session and watching classification fall back to Gemini. + +17. **Commit and push** to `claude/local-oss-model-agents-MEBqj`. Single commit covering Phase 1, message in the form: `feat(executor): add LocalRunner and OpenAI-compat LLM client`. Body describes the two-layer split (Client + Runner), the classifier swap, and the config gating. + +## Stop conditions for Phase 1 + +- All unit tests pass under `-race` +- `go build ./...` clean +- Smoke test against a running Ollama instance produces a `READY` execution with non-zero `tokens_out` and `cost_usd = 0` +- Smoke test with `[local_model]` empty produces unchanged behavior (Gemini classifier path, no LocalRunner registered) +- Branch pushed to remote + +After Phase 1 lands, we stop and decide whether to begin Phase 2 (elaboration). At that point we'll write a Phase 2 focused plan in `docs/plans/local-oss-runner.md`. diff --git a/internal/cli/llm.go b/internal/cli/llm.go new file mode 100644 index 0000000..04fe902 --- /dev/null +++ b/internal/cli/llm.go @@ -0,0 +1,31 @@ +package cli + +import ( + "log/slog" + "net/http" + "time" + + "github.com/thepeterstone/claudomator/internal/config" + "github.com/thepeterstone/claudomator/internal/llm" +) + +// buildLocalLLMClient returns an *llm.Client when a local model endpoint is +// configured.
