Bump the version - -Update the version in `package.json` to the version you want to publish. - -### 2. Run the workflow - -From the GitHub Actions UI: - -- choose **Publish package** -- choose the branch to publish from (default: `main`) -- run the workflow - -## What the workflow does - -The workflow performs these steps: - -1. Checks out the selected branch -2. Sets up Node.js and Bun -3. Reads `name` and `version` from `package.json` -4. Verifies that: - - git tag `v` does not already exist on `origin` - - `@braintrust/trace-opencode@` is not already published on npm -5. Installs dependencies with `bun install --frozen-lockfile` -6. Validates the package by running: - - `bun run check` - - `bun run typecheck` - - `bun run test` - - `bun run build` - - `npm pack --dry-run` -7. Publishes to npm with: - - ```bash - npm publish --provenance --access public - ``` - -8. Creates and pushes the matching git tag: - - ```text - v - ``` - -9. Creates a GitHub release for that tag - -## Notes - -- The package is public, so `package.json` includes: - - ```json - { - "publishConfig": { - "access": "public" - } - } - ``` - -- The publish step relies on npm trusted publishing. No `NPM_TOKEN` secret should be needed. -- If the publish succeeds, npm should show provenance information for the release. - -## Failure modes - -The workflow will fail early if: - -- the git tag for that version already exists -- that exact version is already published on npm -- lint, typecheck, tests, build, or `npm pack --dry-run` fails -- npm trusted publishing is not configured correctly for the package/repo/workflow - -## Troubleshooting - -If npm rejects the publish, verify: - -1. trusted publishing is enabled for `@braintrust/trace-opencode` -2. the repository matches exactly: - - `braintrustdata/braintrust-opencode-plugin` -3. the workflow filename matches exactly: - - `publish-package.yaml` -4. the GitHub Actions job has `id-token: write` - -If needed, update the trusted publishing settings in npm and rerun the workflow. +Publishing a real package is a separate release-only action. It requires an +already validated tarball and the explicit safeguards enforced by +`src/plugins/opencode/publish.sh`. Normal CI and integration work must use only +the dry-run path. diff --git a/src/plugins/opencode/content/package.json b/src/plugins/opencode/content/package.json index 4e19707..3290958 100644 --- a/src/plugins/opencode/content/package.json +++ b/src/plugins/opencode/content/package.json @@ -43,10 +43,6 @@ "dist", "README.md" ], - "dependencies": { - "braintrust": "^0.0.185", - "zod": "^3.23.8" - }, "devDependencies": { "@biomejs/biome": "^2.3.11", "@opencode-ai/plugin": "^1.1.14", diff --git a/src/plugins/opencode/content/src/client.ts b/src/plugins/opencode/content/src/client.ts deleted file mode 100644 index fcca118..0000000 --- a/src/plugins/opencode/content/src/client.ts +++ /dev/null @@ -1,537 +0,0 @@ -/** - * Braintrust API client for the OpenCode plugin - */ - -import { PLUGIN_VERSION } from "./version" - -export interface BraintrustConfig { - profile?: string - apiKey: string - apiUrl?: string - appUrl: string - orgName?: string - projectName: string - tracingEnabled: boolean - enableTools: boolean - debug: boolean - logToFile?: string // Path to write NDJSON log of all plugin I/O, or "auto" for default path - additionalMetadata?: Record - queueSize?: number -} - -/** - * Plugin config from opencode.json `braintrust` section. - * Uses snake_case to match environment variable naming. - */ -export interface PluginConfig { - profile?: string - api_key?: string - api_url?: string - app_url?: string - org_name?: string - project?: string - trace_to_braintrust?: boolean - enable_tools?: boolean - debug?: boolean - log_to_file?: string // Path to write NDJSON log of all plugin I/O, or "true"/"auto" for default path - additional_metadata?: Record - queue_size?: number -} - -export interface SpanData { - id: string - span_id: string - root_span_id: string - span_parents?: string[] - created?: string // ISO timestamp for ordering - input?: unknown - output?: unknown - expected?: unknown - error?: string - scores?: Record - metadata?: Record - metrics?: { - start?: number - end?: number - prompt_tokens?: number - completion_tokens?: number - tokens?: number - prompt_cached_tokens?: number - prompt_cache_creation_tokens?: number - reasoning_tokens?: number - } - context?: { - caller_functionname?: string - caller_filename?: string - caller_lineno?: number - span_origin?: Record - } - span_attributes?: { - name?: string - type?: "llm" | "task" | "tool" | "function" | "eval" | "score" - } - _is_merge?: boolean // When true, merge with existing span by id instead of creating new row -} - -function detectEnvironment(): { type?: string; name?: string } | undefined { - if (process.env.BRAINTRUST_ENVIRONMENT_TYPE || process.env.BRAINTRUST_ENVIRONMENT_NAME) { - return { - ...(process.env.BRAINTRUST_ENVIRONMENT_TYPE - ?
