Option C has no binary, no download, no optional dependencies, and identical behaviour on all platforms. The regex engine is the exact same syntax agents already know from ripgrep and grep β€” so the `keywords` parameter can advertise full regex support transparently. + +OR syntax (`auth|login`), anchors (`^##`), wildcards (`use.*Hook`), and character classes are all native JavaScript regex β€” no ripgrep needed for this. + +MiniSearch (already present in `node_modules`) serves purely as an **optional performance optimisation** for large docsets: rank the most relevant files first, then grep only those.

Parity with baseline. +⁴ MiniSearch is already present in `node_modules` but is not a declared direct dependency of `@codemcp/knowledge-core`; it must be added explicitly, so this is not a clean win. +⁡ Building the MiniSearch index takes ~44–64ms on the tested 46-file docset.

This script fetches the correct platform binary (e.g. `ripgrep-v15.0.0-aarch64-apple-darwin.tar.gz`) from `https://github.com/microsoft/ripgrep-prebuilt/releases`, extracts it, and places `rg` in `node_modules/@vscode/ripgrep/bin/rg`. The JS wrapper (`ripgrep-js` or custom) then calls `child_process.spawn(rgPath, [...args])`. + +**Size:** + +| Component | Size | +| ------------------------------------------------------- | ------------------------------------- | +| `@vscode/ripgrep` JS + deps (yauzl, https-proxy-agent…) | 452 KB installed | +| `rg` binary (macOS ARM64) | **4.3 MB** | +| `rg` binary (Linux x86-64 compressed) | ~1.9 MB compressed / ~5+ MB extracted | +| **Total on disk** | ~4.8 MB | + +**Critical risk:** The `postinstall` download will **silently fail or error** in: + +- Air-gapped / corporate environments without access to `github.com` +- CI systems where GitHub API rate limits are hit +- Environments where `GITHUB_TOKEN` is not set and rate limiting applies + +When the download fails, `rgPath` resolves to a non-existent file and every `search_docs` call throws at runtime. + +--- + +### Option B β€” MiniSearch hybrid + +**How it works:** On first `search_docs` call for a given docset, build a MiniSearch index by reading all files. Cache the index in the server's memory keyed by `docset_id`. On subsequent calls, use the cached index to identify the top-N ranked files, then do a streaming line-by-line regex grep on those files. + +**Pros:** Fuzzy matching (`fronmattr` β†’ `frontmatter`), prefix matching (`auth` β†’ `authentication`), ranked results. +**Cons:** Index must be rebuilt if docset is re-initialized; adds state to the server; MiniSearch results are document-level and require a second grep pass for line numbers; 44–64ms cold start. + +--- + +### Option C β€” Pure Node.js streaming regex grep (chosen) + +**How it works:** + +1. Walk the docset directory with `fs.promises.readdir` (recursive, or via a `walk` generator). +2. Skip binary files by checking the first 8 KB for null bytes. +3. Skip ignored paths: `node_modules/`, `.git/`, `dist/`, `build/`, `.agentic-metadata.json`. +4. For each text file, open a `readline` stream and test each line against `new RegExp(keywords, 'i')`. +5. Collect matches with 2 lines of before/after context. +6. Cap results at 50 matches; set `truncated: true` if cap is hit. +7. If 0 matches and `generalized_keywords` is provided, repeat with that pattern. + +**Syntax advertised to agents:** + +``` +Supports full regex syntax (e.g. "log.*Error", "function\s+\w+", "auth|login"). +Filter by file pattern with include parameter (e.g. "*.md", "*.ts"). +Use generalized_keywords for broader synonyms if primary pattern returns no results. +``` + +This syntax is identical to ripgrep's default regex mode β€” agents that know ripgrep will use it correctly without any learning curve. + +--- + +## Links + +- [MiniSearch documentation](https://lucaong.github.io/minisearch/) +- [microsoft/ripgrep-prebuilt releases](https://github.com/microsoft/ripgrep-prebuilt/releases) +- [@vscode/ripgrep source](https://github.com/microsoft/vscode-ripgrep) +- [Nygard ADR template](https://github.com/joelparkerhenderson/architecture-decision-record/blob/main/locales/en/templates/decision-record-template-by-michael-nygard/index.md) diff --git a/package.json b/package.json index f803291..5b1e5f5 100644 --- a/package.json +++ b/package.json @@ -8,7 +8,7 @@ "agentic-knowledge": "packages/cli/dist/index.js" }, "engines": { - "node": ">=18.0.0", + "node": ">=20.0.0", "pnpm": ">=9.0.0" }, "packageManager": "pnpm@10.29.3", diff --git a/packages/core/package.json b/packages/core/package.json index 003accf..b64e508 100644 --- a/packages/core/package.json +++ b/packages/core/package.json @@ -29,7 +29,8 @@ "typecheck": "tsc --noEmit" }, "dependencies": { - "js-yaml": "^4.1.0" + "js-yaml": "^4.1.0", + "minisearch": "^7.1.2" }, "devDependencies": { "@eslint/js": "^9.34.0", diff --git a/packages/core/src/__tests__/searcher.test.ts b/packages/core/src/__tests__/searcher.test.ts new file mode 100644 index 0000000..f224ec2 --- /dev/null +++ b/packages/core/src/__tests__/searcher.test.ts @@ -0,0 +1,341 @@ +/** + * Tests for the docset searcher (ADR-001 Option C: Node.js streaming regex grep) + */ + +import { describe, test, expect, beforeAll, afterAll } from "vitest";
