+# @haylan/opencode-fastcrw
+
+An [opencode](https://opencode.ai) v2 plugin that makes a self-hosted [fastCRW](https://docs.fastcrw.com) server opencode's websearch. It calls `POST {baseURL}/v1/search` directly; it does not use the `crw-mcp` MCP server.
+
+The plugin registers a search provider with id `fastcrw` and makes it the default. If fastCRW fails, searches fail; they never fall back to the built-in providers (Exa, Firecrawl, Parallel, Tavily, TinyFish).
+
+## Install
+
+The package is published to the Gitea npm registry. Map the scope to it in your `.npmrc`:
+
+```
+@haylan:registry=https://git.arthurerlich.de/api/packages/haylan/npm/
+```
+
+Then add the plugin to your `opencode.json`:
+
+```jsonc
+{
+  "plugins": [
+    {
+      "package": "@haylan/opencode-fastcrw",
+      "options": { "baseURL": "http://crw.home:3000" },
+    },
+  ],
+}
+```
+
+Installing by name from the Gitea registry has not been verified end to end yet; see [docs/runtime-checks.md](docs/runtime-checks.md).
+
+### Local build
+
+To try the plugin without a registry:
+
+```bash
+npm ci
+npm run build
+```
+
+opencode loads local plugins as directories, resolved by file path (`<dir>/server`, then `<dir>/index`), and ignores `package.json` `exports`, so this package cannot be pointed at directly. Use a small shim instead. Create `~/.config/opencode/plugins/fastcrw.js` (a `.js` or `.ts` file; `.mjs` is ignored) with:
+
+```js
+export { default } from "file:///ABSOLUTE/PATH/TO/fastcrw-opencode-websarch/dist/index.js"
+```
+
+A drop-in file cannot receive plugin options, so configure the plugin with the environment variables below (`CRW_API_URL`, `CRW_API_KEY`). To use options instead, put the same line in an `index.js` inside a directory and reference that directory as `"package": "./that-dir"` (a relative path is resolved from the config file; `~` is not expanded).
+
+## Configuration
+
+Plugin options come from `opencode.json`. Precedence is option, then environment variable, then default.
+
+| Option    | Environment variable | Default                 | Notes                                                                                   |
+| --------- | -------------------- | ----------------------- | --------------------------------------------------------------------------------------- |
+| `baseURL` | `CRW_API_URL`        | `http://localhost:3000` | Base URL of the fastCRW server, `http` or `https`. Trailing slashes are removed.        |
+| `apiKey`  | `CRW_API_KEY`        | none                    | Optional. Sent as a Bearer token. Prefer the environment variable over `opencode.json`. |
+| `limit`   | none                 | `8`                     | Results per search, clamped to 1 to 20. An invalid value falls back to 8.               |
+| `lang`    | none                 | unset                   | Search language, for example `en` or `de`. Omitted from the request when unset.         |
+| `tbs`     | none                 | unset                   | Time range: `qdr:h`, `qdr:d`, `qdr:w`, `qdr:m` or `qdr:y`.                              |
+
+A bad `baseURL`, `tbs`, `lang` or `apiKey` makes the plugin fail to load, with a message naming the option. opencode keeps running and shows the plugin as failed.
+
+### Choosing the provider
+
+Do not set `websearch.provider` to another provider. In opencode, a provider named in `opencode.json` wins over the one a plugin sets as default, so `"websearch": { "provider": "exa" }` would send your searches to Exa. Leaving it unset, or setting it to `"fastcrw"`, uses this plugin.
+
+## Errors
+
+Failures are thrown as `fastCRW <status> <error_code>: <message>`, with a hint for a missing or invalid key (401) and for a server without a search backend (503 `search_disabled`). A server that is unreachable, times out (30 s) or returns something that is not JSON gets its own message. opencode currently shows only a generic "Web search request failed: fastcrw", so check the server when searches fail.
+
+A self-hosted fastCRW server needs a SearXNG-style search backend (`CRW_SEARCH__SEARCH_BACKEND_URL`); without one, searches return 503.
+
+## Development
+
+```bash
+npm ci
+npm run check   # Prettier and type check
+npm test        # node --test, needs Node 22.18 or later
+npm run build   # compile to dist/
+npm run smoke -- "query"   # one real search against CRW_API_URL (manual)
+```
+
+`docs/spec.md` is the build spec, `docs/runtime-checks.md` records what was verified against a real opencode, and `CONTEXT.md` defines the vocabulary.
+
+### Releasing
+
+Releases are published by the manually started `release` workflow on Gitea Actions. It reads the latest version heading in `CHANGELOG.md` (the repository keeps the dev version `0.0.0-dev` in `package.json`) and then:
+
+1. publishes that version to the Gitea npm registry, unless it already exists;
+2. tags the workflow's commit `v<version>`, unless the tag already exists;
+3. links the package to this repository, unless it is already linked.
+
+Every step skips itself when done, so starting the workflow again completes a release that only partly succeeded.
+
+To release: add a dated `## [x.y.z]` entry to `CHANGELOG.md`, merge it to `main`, then start the workflow. It needs a token with `write:package` and `write:repository` rights: the job token if it has them, otherwise a `PACKAGE_TOKEN` secret.

+
+## How plugins load (read this first)
+
+Read from the opencode binary and confirmed with hello-world plugins:
+
+- A `plugins` entry in `opencode.json` that points at a **file** is ignored with the warning "configured plugin path must be a directory". It must be a directory, or an npm package name.
+- A local directory is resolved **by file path**: `<dir>/server` then `<dir>/index`. The directory's `package.json` `exports` are not used. This repo has no root `index.js` (the entry is `dist/index.js`), so pointing a config entry at the repo or an unpacked package directory loads nothing and logs nothing. My first three attempts failed for this reason.
+- An npm package name resolves through `exports` (`<name>/server`, then `<name>`), so `exports["."]` works for registry installs (still unverified end to end, check 4).
+- Auto-discovery in `plugins/` folders (global config dir or project `.opencode/`) accepts only `.ts` and `.js` files and directories. `.mjs` files are ignored.
+- `~` paths are not expanded; use `./relative`, an absolute path or `file://`. The `~/.config/opencode/plugins/fastcrw` example in the original sketch does not work.
+- Loading is lazy: the plugin list is empty for several seconds after startup or `POST /api/location/reload`.
+
+With a one-line directory shim (`index.js`: `export { default } from "file:///.../dist/index.js"`) the real plugin loaded, registered provider `fastcrw`, honoured `baseURL` and `limit` from the plugin options, and returned the mapped result for `POST /api/websearch`.
+
+## Findings
+
+### 1. Built-in providers
+
+The plugin API has no way to remove a provider (`WebSearchEditor` only has `add` and `default`), so the built-ins (exa, firecrawl, parallel, tavily, tinyfish) stay registered. In practice fastCRW is still the only one used:
+
+- With no `websearch` config, the plugin's `editor.default.set("fastcrw")` makes it the default.
+- When fastCRW was unreachable or returned 429, opencode answered 503 "Web search request failed: fastcrw". It did **not** fall back to a built-in.
+- If no default is set (for example the plugin failed to load), a query without a provider id is rejected with 400 "Web search provider is required".
+
+### 2. Throwing `setup`
+
+With `baseURL: "nope"`, only this plugin ended up in state `failed`, with our message and stack (`fastCRW: invalid baseURL "nope" (expected an http(s) URL)`), and a `WARN failed to load plugin` line was logged. The other plugins stayed `active` and the server kept running. The provider is then not registered. The plan holds: fail loudly, no silent search elsewhere.
+
+### 3. Precedence
+
+Config `websearch.provider` wins over the plugin's `editor.default.set`: with the config set to `exa`, a query without a provider id went to Exa (and worked without a key, so the query left the machine). With the config unset or set to `fastcrw`, the plugin's provider was used. Consequence: do not set `websearch.provider` to anything else; setting it to `fastcrw` is harmless and explicit.
+
+### 6. `@opencode/plugin` install weight
+
+`npm install` of `@opencode/plugin@2.0.22` adds about 100 MB of transitive dependencies (mainly `effect`, OpenTelemetry, `@redis`). Its peers `solid-js`, `@opentui/core`, `@opentui/solid` and `@opencode/theme` are optional and not installed. Decision for the first release: keep it in `dependencies` as the docs say; revisit if install size matters.
+
+### 7. Smoke test
+
+Run against `http://crw.home` and `http://192.168.2.15:8013` (the same server; earlier attempts failed on DNS, a refused connection and an upstream 502 until the service came up). No token was needed. The envelope is `{ success, data }` and `data` is an object, so this server returns the self-hosted shape `data.results`, not a flat array; the plugin's dual-shape parser handles it. Each result has `url`, `title`, `description`, `snippet`, `position`, `score` and `category`.
+
+### 8. Typings, `time`, 429
+
+From `@opencode/schema` 2.0.22: a result is `{ url: string, title?: string, content?: string, time: { published?: number } }`, so `time: {}` is valid; `execute` receives `({ query }, { signal })`; `editor.default.set(selection: string | false)`. A 429 from fastCRW surfaced as a plain failure: three queries in a row all reached the server, so no provider cooldown was triggered. opencode also shows only the generic "Web search request failed: fastcrw" through the API; our detailed message was not visible there or in the debug log.
+
+## Follow-ups this implies
+
+- **Local installs need a root `index.js`.** Add `index.js` (`export { default } from "./dist/index.js"`) to the package and `files`, so a config entry pointing at an unpacked package directory works as well as an npm-name install. The release script stages `package.json` and `dist/` only and would need to include it.
+- Update the README and spec examples: no `~` paths, and a directory (not a file) for local `plugins` entries.
+- Optional: decide whether the generic user-facing error is acceptable, since our detailed messages are not surfaced.
+- Still to verify after the first release: check 4 (install by name with a scoped `.npmrc`) and check 5 (job token package-write rights).
+
+## Useful for later runs
+
+- `opencode serve --hostname 127.0.0.1 --port <p>` prints a generated server password; HTTP Basic auth with user `opencode` works. `GET /openapi.json` lists the API.
+- Relevant operations: `GET /api/plugin` (shows `state`, including load errors), `GET /api/websearch/provider`, `POST /api/websearch` (body `query`, optional `providerID`), `POST /api/location/reload`.
+- `opencode debug config` hung in an empty profile; `opencode plugin add` writes to the global config, so avoid it on a real machine.
