+# Function Templates — Agent Guide
+
+## What Is This Repo?
+
+Templates for [Knative Functions](https://github.com/knative/func). Users create
+functions via `func create -r <this-repo> -l <language> -t <template>`.
+
+```bash
+# Example: create a Go function from the "hello" template
+func create myfunc -r https://github.com/functions-dev/templates -l go -t hello
+```
+
+All files in a template directory are copied to the user's project (except `manifest.yaml`
+which holds some metadata that the function will need and hidden files).
+
+## Using Templates (This repository)
+
+Templates are organized as `<language>/<template>/`. The `-l` flag matches the language
+directory, the `-t` flag matches the template subdirectory:
+
+```
+go/hello/               →  func create -l go -t hello
+python/echo/            →  func create -l python -t echo
+rust/echo-cloudevents/  →  func create -l rust -t echo-cloudevents
+```
+
+### Template Index
+
+Available in all languages (go, node, python, quarkus, rust, springboot, typescript):
+
+| Template | Description |
+|---|---|
+| `hello` | Returns `{"message":"Hello <Language> World!"}`. Simplest starting point. |
+| `echo` | Echoes back the request. GET returns query string, POST returns body. |
+| `echo-cloudevents` | Receives a CloudEvent, echoes the data back as a new CloudEvent. |
+
+Go-specific:
+
+| Template | Description |
+|---|---|
+| `go/blog` | Hugo-powered blog served as static files. Requires `make` to build before use. |
+| `go/splash` | Static splash page serving HTML, CSS, and PNG files. |
+
+Python-specific:
+
+| Template | Description |
+|---|---|
+| `python/pdf-processing` | PDF operations (extract text, metadata, split, merge) via HTTP. |
+| `python/mcp` | MCP server exposing basic tools (hello, add_numbers) via Model Context Protocol. |
+| `python/mcp-ollama` | Exposes Ollama LLM as MCP tools (list/pull/call models). Needs Ollama. |
+| `python/mcp-ollama-rag` | RAG via MCP — combines Ollama with Chroma vector DB for document Q&A. Needs Ollama. |
+| `python/ollama-client` | HTTP wrapper that forwards prompts to a local Ollama server. Needs Ollama. |
+| `python/llamacpp` | Loads a Granite code model via llama.cpp for local text generation. |

+## Running Tests
+
+```bash
+make test            # all runtimes
+make test-go         # single runtime
+make test-python     # etc.
+```
+
+Detailed logs go to `test-results.log`. Skipped templates and reasons are listed
+at the top of the Makefile.
+
+## Adding a New Template
+
+1. Create `<language>/<template-name>/` with function source files
+2. Add tests following existing patterns per language:
+   - Go: `*_test.go`
+   - Python: `tests/test_func.py`, deps in `pyproject.toml` (under `dependencies` or `[project.optional-dependencies] dev`)
+   - Node: `test/unit.js` + `test/integration.js`, `npm test` script in `package.json`
+   - TypeScript: `test/unit.ts` + `test/integration.ts`, `npm test` script in `package.json`
+   - Rust: `#[cfg(test)]` module in `handler.rs`
+   - Quarkus/SpringBoot: `src/test/java/`
+3. If it needs external services, add to the skip list in Makefile with a comment
+4. CI picks it up automatically — both workflows discover templates dynamically
+
+Remember: every file in the template directory gets copied to the user's project
+via `func create`. Only include files the user would want.
+
+## CI Workflows
+
+| Workflow | What It Does | Triggers |
+|---|---|---|
+| `invoke-all.yaml` | Builds and invokes every template end-to-end | push to main, PRs, manual |
+| `test-templates.yaml` | Runs unit tests via `make test` | push to main, PRs |
+
+Both workflows discover templates dynamically from the directory structure.
+
+## Key Constraints
+
+- **No git submodules** — `func create` does not fetch them. Use vendored deps or
+  language-native module systems (e.g. Hugo modules for go/blog).
+- **`manifest.yaml`** — Optional per-template config for build settings (builder images,
+  buildpacks, envs, health endpoints). Not copied to the user's project. Can be defined
+  at repo, language, or template level with inheritance.
