## Description `headroom wrap opencode` looked like it worked (proxy started, opencode launched) but **no inference reached the proxy**, so users saw zero savings (#1572). Root causes: 1. The injected synthetic `headroom` provider (`@ai-sdk/openai-compatible`) had **no `models` and no `apiKey`** → opencode raised `ProviderModelNotFoundError`, and it only ever targets OpenAI. 2. The wrap injected a reference to the **unpublished `headroom-opencode` npm plugin**, which opencode silently failed to resolve → the transparent transport never loaded. 3. Serena was launched with `--context opencode`, a context Serena does not ship → crash on launch (#1549). This PR makes `headroom wrap opencode` route opencode's traffic through the proxy with the user's **own API key** (no key written to disk), and gets the transparent transport plugin actually loading. Closes #1572 Closes #1549 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) ## Changes Made - **`runtime.py`** — two complementary routing layers (both verified against opencode 1.17): 1. Override opencode's native `anthropic`/`openai` provider `baseURL` to the proxy. Reliable, credential-independent (covers API key **and** subscription), keeps native model metadata/limits, reuses the user's existing key. This is the always-on layer and the only one a pip-only install needs. 2. Load the transport plugin **by absolute path** when it has been built (`headroom_opencode_plugin_path()`), self-configured via `HEADROOM_PROXY_URL`. Covers providers we don't name (Gemini, Copilot, custom gateways) and providers added mid-session. Loopback URLs aren't double-routed, so the two layers coexist. - **`wrap.py`** — Serena context `opencode` → `agent` (valid context). - **`plugins/opencode/`** — new `src/entry.opencode.ts` loader entry that exports **only** the plugin function (opencode rejects a module with non-function exports: "Plugin export is not a function"); tsup builds it as a second entry. - **tests** — updated `test_providers_opencode_config.py` for path-based plugin injection + a skip-when-unbuilt case. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ python -m pytest tests/test_providers_opencode_config.py tests/test_cli/test_wrap_opencode.py -q 72 passed in 0.59s $ (cd plugins/opencode && npm test) Test Files 2 passed (2) Tests 9 passed (9) $ ruff check headroom/providers/opencode/runtime.py headroom/cli/wrap.py tests/test_providers_opencode_config.py ✓ Ruff: No issues found $ mypy headroom/providers/opencode/runtime.py Success: no issues found in 1 source file ``` ## Real Behavior Proof - **Environment:** macOS, opencode 1.17.11 (npm), headroom proxy 0.28.0 (local), Anthropic API key from `.env`. - **Exact command:** ``` headroom wrap opencode --no-serena --no-context-tool --no-proxy --port 8787 \ -- run -m anthropic/claude-haiku-4-5-20251001 "Reply with exactly: WRAPWORKS" ``` - **Observed result:** opencode printed `plugin=headroom-opencode` (loaded, no error) and returned `WRAPWORKS`. The proxy log shows the request routed through it: ``` event=outbound_request method=POST path=https://api.anthropic.com/v1/messages source=passthrough event=proxy_inbound_response path=/v1/messages status=200 PERF model=claude-haiku-4-5-20251001 cache_hit_pct=97 client=opencode ``` Compression verified on a large tool_result (`client=opencode`): ``` Pipeline complete: 170653 -> 77 tokens (saved 170576, 100.0% reduction) PERF tok_before=151309 tok_after=67 tok_saved=151242 transforms=router:tool_result:log client=opencode ``` - **Not tested:** custom OpenAI-compatible gateways (need the proxy to honor `x-headroom-base-url` in the dedicated OpenAI handler — open PR #1502); interactive TUI (verified the headless `opencode run` path). ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Additional Notes - **Plugin shipping:** the plugin loads by repo-relative path, which works for source/editable installs. `plugins/opencode/dist/` is gitignored, so the plugin must be built (`cd plugins/opencode && npm install && npm run build`) for layer 2 to activate; pip-only installs gracefully fall back to layer 1 (native baseURL override). Bundling `dist/` into the package or publishing `headroom-opencode` to npm is a follow-up for universal shipping. - **CHANGELOG:** N/A — handled by Release Please from the conventional commit. - Custom-gateway support depends on existing PR #1502 (honor `x-headroom-base-url` in the dedicated OpenAI handlers); not duplicated here. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |
