Reference Patterns

Personal reference of implementation and testing patterns across languages (TypeScript, Go, Protobuf — Rust and more as they come). Each pattern is a self-contained, runnable example documented in its PATTERN.md, meant to be consumed from other projects through MCP.

Layout

<language>/<category>/<pattern-slug>/
├── PATTERN.md    # frontmatter (name, tags, description, origin, test command) + Problem/Solution/Path/Key points
└── ...           # runnable code with its own manifest (package.json, go.mod, buf.yaml, ...)

• llms.txt is the generated index of every pattern — this is what MCP clients read first.
• Patterns never depend on each other.
• Each language directory is a workspace managed by its native tool: pnpm-workspace.yaml (with a catalog: as the single place to bump TypeScript dependency versions), go.work, and per-crate Cargo for Rust. One root pnpm install covers every TypeScript pattern; bumping a catalog version + running ./scripts/test-all.sh re-verifies the whole reference at once. Toolchains needed locally: node + pnpm, go, buf, rust + cargo.

Consume via MCP (GitMCP)

This repo is served as an MCP server by GitMCP — no hosting, it reads the public repo directly. From any project:

claude mcp add --transport http patterns https://gitmcp.io/Skayfa/reference-patterns

or in mcpServers:

"patterns": {
  "type": "http",
  "url": "https://gitmcp.io/Skayfa/reference-patterns"
}

Exposed tools: fetch_reference_docs (returns llms.txt), search_reference_docs, search_reference_code, fetch_generic_url_content.

Add a pattern

1. Copy templates/pattern/PATTERN.md into <language>/<category>/<slug>/.
2. Fill the frontmatter — description is what MCP search matches against; origin records where the pattern was distilled from (source project + month); test is the command scripts/test-all.sh runs from the pattern directory (none for docs-only patterns).
3. Add the runnable code with its own manifest. TypeScript patterns are picked up by the workspace glob automatically — use "catalog:" versions (add new entries to pnpm-workspace.yaml) and test: pnpm test.
4. ./scripts/generate-llms.sh to refresh the index.
5. ./scripts/test-all.sh — everything must pass before pushing.

Test everything

./scripts/test-all.sh
