From a88b47bf19c6df92c8e85ce69c11bb09e65e91f7 Mon Sep 17 00:00:00 2001 From: Erik van der Boom Date: Sun, 19 Apr 2026 22:33:16 +0200 Subject: [PATCH] ci: add OS matrix, tool-parity guard, and coverage job Expand CI to ubuntu + windows + macos. Add a tool-parity check that verifies all four surfaces (mcp-ts index.ts, vscode-ext mcp.ts, vscode-ext package.json, mcpb manifest.json) declare the same tools. Add a coverage job that runs vitest with @vitest/coverage-v8 and enforces 80/65/90/80 thresholds for statements/branches/functions/lines. --- .github/workflows/ci.yml | 48 +++++++++++++++- .gitignore | 1 + scripts/check-tool-parity.mjs | 103 ++++++++++++++++++++++++++++++++++ 3 files changed, 149 insertions(+), 3 deletions(-) create mode 100644 scripts/check-tool-parity.mjs diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 417fb0f..4a8621a 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -10,7 +10,11 @@ permissions: jobs: test: name: Test & template-sync check - runs-on: ubuntu-latest + runs-on: ${{ matrix.os }} + strategy: + fail-fast: false + matrix: + os: [ubuntu-latest, windows-latest, macos-latest] env: FORCE_JAVASCRIPT_ACTIONS_TO_NODE24: true @@ -39,7 +43,7 @@ jobs: if: always() uses: actions/upload-artifact@v7 with: - name: mcp-test-results + name: mcp-test-results-${{ matrix.os }} path: mcp-ts/test-results.json # ── Template sync ───────────────────────────────────────────────────────── @@ -65,5 +69,43 @@ jobs: if: always() uses: actions/upload-artifact@v7 with: - name: vscode-ext-test-results + name: vscode-ext-test-results-${{ matrix.os }} path: vscode-ext/test-results.json + + # ── Job: Coverage gates ────────────────────────────────────────────────────── + # Runs coverage-with-thresholds on ubuntu only (one platform is enough — coverage + # numbers don't depend on OS, and per-OS coverage runs would triple CI time). + coverage: + name: Coverage (v8) + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v6 + - uses: actions/setup-node@v6 + with: + node-version: '22' + cache: 'npm' + cache-dependency-path: | + mcp-ts/package-lock.json + vscode-ext/package-lock.json + + - name: Install mcp-ts + run: cd mcp-ts && npm ci + - name: mcp-ts coverage + run: cd mcp-ts && npm run test:coverage + + - name: Sync templates to vscode-ext + run: cp mcp-ts/src/templates.ts vscode-ext/src/ai-setup-templates.ts + + - name: Install vscode-ext + run: cd vscode-ext && npm ci + - name: vscode-ext coverage + run: cd vscode-ext && npm run test:coverage + + - name: Upload coverage reports + if: always() + uses: actions/upload-artifact@v7 + with: + name: coverage + path: | + mcp-ts/coverage/ + vscode-ext/coverage/ diff --git a/.gitignore b/.gitignore index 2d5e8ee..c6c3c19 100644 --- a/.gitignore +++ b/.gitignore @@ -12,6 +12,7 @@ mcp-rust/target/ # Test artifacts test-results.json +coverage/ # Environment (contains personal paths) .env diff --git a/scripts/check-tool-parity.mjs b/scripts/check-tool-parity.mjs new file mode 100644 index 0000000..cbe11ec --- /dev/null +++ b/scripts/check-tool-parity.mjs @@ -0,0 +1,103 @@ +#!/usr/bin/env node +/** + * MCP tool parity guard. + * + * Verifies every tool name appears in all 5 required surfaces: + * 1. mcp-ts/src/tools.ts — implementation function `toolXxx` + * 2. mcp-ts/src/index.ts — server.registerTool('bindery_xxx', ...) + * 3. vscode-ext/src/mcp.ts — vscode.lm.registerTool('bindery_xxx', ...) + * 4. vscode-ext/package.json — languageModelTools[].name = 'bindery_xxx' + * 5. mcpb/manifest.json — tools[].name = 'xxx' (no prefix) + * + * Source of truth: the set of tool names in mcp-ts/src/index.ts. + * Exits with code 1 if any surface diverges. + */ + +import * as fs from 'node:fs'; +import * as path from 'node:path'; +import { fileURLToPath } from 'node:url'; + +const repoRoot = path.resolve(path.dirname(fileURLToPath(import.meta.url)), '..'); + +function read(p) { + return fs.readFileSync(path.join(repoRoot, p), 'utf-8'); +} + +function extractMatches(source, regex) { + const names = new Set(); + for (const m of source.matchAll(regex)) { + names.add(m[1]); + } + return names; +} + +// ── Surface 1: mcp-ts/src/index.ts — registerTool('xxx', ...)
