-- **[Greenfield .NET CLI tool](https://github.com/mnriem/spec-kit-dotnet-cli-demo)** — Builds a Timezone Utility as a .NET single-binary CLI tool from a blank directory, covering the full spec-kit workflow: constitution, specify, plan, tasks, and multi-pass implement using GitHub Copilot agents.
-
-- **[Greenfield Spring Boot + React platform](https://github.com/mnriem/spec-kit-spring-react-demo)** — Builds an LLM performance analytics platform (REST API, graphs, iteration tracking) from scratch using Spring Boot, embedded React, PostgreSQL, and Docker Compose, with a clarify step and a cross-artifact consistency analysis pass included.
-
-- **[Brownfield ASP.NET CMS extension](https://github.com/mnriem/spec-kit-aspnet-brownfield-demo)** — Extends an existing open-source .NET CMS (CarrotCakeCMS-Core, ~307,000 lines of C#, Razor, SQL, JavaScript, and config files) with two new features — cross-platform Docker Compose infrastructure and a token-authenticated headless REST API — demonstrating how spec-kit fits into existing codebases without prior specs or a constitution.
-
-- **[Brownfield Java runtime extension](https://github.com/mnriem/spec-kit-java-brownfield-demo)** — Extends an existing open-source Jakarta EE runtime (Piranha, ~420,000 lines of Java, XML, JSP, HTML, and config files across 180 Maven modules) with a password-protected Server Admin Console, demonstrating spec-kit on a large multi-module Java project with no prior specs or constitution.
-
-- **[Brownfield Go / React dashboard demo](https://github.com/mnriem/spec-kit-go-brownfield-demo)** — Demonstrates spec-kit driven entirely from the **terminal using GitHub Copilot CLI**. Extends NASA's open-source Hermes ground support system (Go) with a lightweight React-based web telemetry dashboard, showing that the full constitution → specify → plan → tasks → implement workflow works from the terminal.
-
-- **[Greenfield Spring Boot MVC with a custom preset](https://github.com/mnriem/spec-kit-pirate-speak-preset-demo)** — Builds a Spring Boot MVC application from scratch using a custom pirate-speak preset, demonstrating how presets can reshape the entire spec-kit experience: specifications become "Voyage Manifests," plans become "Battle Plans," and tasks become "Crew Assignments" — all generated in full pirate vernacular without changing any tooling.
-
-- **[Greenfield Spring Boot + React with a custom extension](https://github.com/mnriem/spec-kit-aide-extension-demo)** — Walks through the **AIDE extension**, a community extension that adds an alternative spec-driven workflow to spec-kit with high-level specs (vision) and low-level specs (work items) organized in a 7-step iterative lifecycle: vision → roadmap → progress tracking → work queue → work items → execution → feedback loops. Uses a family trading platform (Spring Boot 4, React 19, PostgreSQL, Docker Compose) as the scenario to illustrate how the extension mechanism lets you plug in a different style of spec-driven development without changing any core tooling — truly utilizing the "Kit" in Spec Kit.

+# Community Walkthroughs
+
+> [!NOTE]
+> Community walkthroughs are independently created and maintained by their respective authors. They are **not reviewed, nor endorsed, nor supported by GitHub**. Review their content before following along and use at your own discretion.
+
+See Spec-Driven Development in action across different scenarios with these community-contributed walkthroughs:
+
+- **[Greenfield .NET CLI tool](https://github.com/mnriem/spec-kit-dotnet-cli-demo)** — Builds a Timezone Utility as a .NET single-binary CLI tool from a blank directory, covering the full spec-kit workflow: constitution, specify, plan, tasks, and multi-pass implement using GitHub Copilot agents.
+
+- **[Greenfield Spring Boot + React platform](https://github.com/mnriem/spec-kit-spring-react-demo)** — Builds an LLM performance analytics platform (REST API, graphs, iteration tracking) from scratch using Spring Boot, embedded React, PostgreSQL, and Docker Compose, with a clarify step and a cross-artifact consistency analysis pass included.
+
+- **[Brownfield ASP.NET CMS extension](https://github.com/mnriem/spec-kit-aspnet-brownfield-demo)** — Extends an existing open-source .NET CMS (CarrotCakeCMS-Core, ~307,000 lines of C#, Razor, SQL, JavaScript, and config files) with two new features — cross-platform Docker Compose infrastructure and a token-authenticated headless REST API — demonstrating how spec-kit fits into existing codebases without prior specs or a constitution.
+
+- **[Brownfield Java runtime extension](https://github.com/mnriem/spec-kit-java-brownfield-demo)** — Extends an existing open-source Jakarta EE runtime (Piranha, ~420,000 lines of Java, XML, JSP, HTML, and config files across 180 Maven modules) with a password-protected Server Admin Console, demonstrating spec-kit on a large multi-module Java project with no prior specs or constitution.
+
+- **[Brownfield Go / React dashboard demo](https://github.com/mnriem/spec-kit-go-brownfield-demo)** — Demonstrates spec-kit driven entirely from the **terminal using GitHub Copilot CLI**. Extends NASA's open-source Hermes ground support system (Go) with a lightweight React-based web telemetry dashboard, showing that the full constitution → specify → plan → tasks → implement workflow works from the terminal.
+
+- **[Greenfield Spring Boot MVC with a custom preset](https://github.com/mnriem/spec-kit-pirate-speak-preset-demo)** — Builds a Spring Boot MVC application from scratch using a custom pirate-speak preset, demonstrating how presets can reshape the entire spec-kit experience: specifications become "Voyage Manifests," plans become "Battle Plans," and tasks become "Crew Assignments" — all generated in full pirate vernacular without changing any tooling.
+
+- **[Greenfield Spring Boot + React with a custom extension](https://github.com/mnriem/spec-kit-aide-extension-demo)** — Walks through the **AIDE extension**, a community extension that adds an alternative spec-driven workflow to spec-kit with high-level specs (vision) and low-level specs (work items) organized in a 7-step iterative lifecycle: vision → roadmap → progress tracking → work queue → work items → execution → feedback loops. Uses a family trading platform (Spring Boot 4, React 19, PostgreSQL, Docker Compose) as the scenario to illustrate how the extension mechanism lets you plug in a different style of spec-driven development without changing any core tooling — truly utilizing the "Kit" in Spec Kit.

+### Composition Strategies
+
+Templates, commands, and scripts support a `strategy` field that controls how a preset's content is combined with lower-priority content instead of fully replacing it:
+
+| Strategy | Description | Templates | Commands | Scripts |
+|----------|-------------|-----------|----------|---------|
+| `replace` (default) | Fully replaces lower-priority content | ✓ | ✓ | ✓ |
+| `prepend` | Places content before lower-priority content (separated by a blank line) | ✓ | ✓ | — |
+| `append` | Places content after lower-priority content (separated by a blank line) | ✓ | ✓ | — |
+| `wrap` | Content contains `{CORE_TEMPLATE}` (templates/commands) or `$CORE_SCRIPT` (scripts) placeholder replaced with lower-priority content | ✓ | ✓ | ✓ |
+
+Composition is recursive — multiple composing presets chain. The `PresetResolver.resolve_content()` method walks the full priority stack bottom-up and applies each layer's strategy.
+
+Content resolution functions for composition:
+- **Python**: `PresetResolver.resolve_content()` in `src/specify_cli/presets.py` (templates, commands, and scripts)

 When a preset is installed with `type: "command"` entries, the `PresetManager` registers them into all detected agent directories using the shared `CommandRegistrar` from `src/specify_cli/agents.py`.

-Presets **override**, they don't merge. If two presets both provide `spec-template`, the one with the lowest priority number wins entirely.
+Presets **override by default**, they don't merge. If two presets both provide `spec-template` with the default `replace` strategy, the one with the lowest priority number wins entirely. However, presets can use **composition strategies** to augment rather than replace content.
+
+### Composition Strategies
+
+Presets can declare a `strategy` per template to control how content is combined. The `name` field identifies which template to compose with in the priority stack, while `file` points to the actual content file (which can differ from the convention path `templates/<name>.md`):
+
+```yaml
+provides:
+  templates:
+    - type: "template"
+      name: "spec-template"
+      file: "templates/spec-addendum.md"
+      strategy: "append"        # adds content after the core template
+```
+
+| Strategy | Description |
+|----------|-------------|
+| `replace` (default) | Fully replaces the lower-priority template |
+| `prepend` | Places content **before** the resolved lower-priority template, separated by a blank line |
+| `append` | Places content **after** the resolved lower-priority template, separated by a blank line |
+| `wrap` | Content contains `{CORE_TEMPLATE}` placeholder (or `$CORE_SCRIPT` for scripts) replaced with the lower-priority content |
+
+**Supported combinations:**
+
+| Type | `replace` | `prepend` | `append` | `wrap` |
+|------|-----------|-----------|----------|--------|
+| **template** | ✓ (default) | ✓ | ✓ | ✓ |
+| **command** | ✓ (default) | ✓ | ✓ | ✓ |
+| **script** | ✓ (default) | — | — | ✓ |
+
+Multiple composing presets chain recursively. For example, a security preset with `prepend` and a compliance preset with `append` will produce: security header + core content + compliance footer.

 The following enhancements are under consideration for future releases:
 
-- **Composition strategies** — Allow presets to declare a `strategy` per template instead of the default `replace`:
-
-  | Type | `replace` | `prepend` | `append` | `wrap` |
-  |------|-----------|-----------|----------|--------|
-  | **template** | ✓ (default) | ✓ | ✓ | ✓ |
-  | **command** | ✓ (default) | ✓ | ✓ | ✓ |
-  | **script** | ✓ (default) | — | — | ✓ |
-
-  For artifacts and commands (which are LLM directives), `wrap` would inject preset content before and after the core template using a `{CORE_TEMPLATE}` placeholder. For scripts, `wrap` would run custom logic before/after the core script via a `$CORE_SCRIPT` variable.
-- **Script overrides** — Enable presets to provide alternative versions of core scripts (e.g. `create-new-feature.sh`) for workflow customization. A `strategy: "wrap"` option could allow presets to run custom logic before/after the core script without fully replacing it.
+- **Structural merge strategies** — Parsing Markdown sections for per-section granularity (e.g., "replace only ## Security").
+- **Conflict detection** — `specify preset lint` / `specify preset doctor` for detecting composition conflicts.

+# Lean Workflow
+
+A minimal preset that strips the Spec Kit workflow down to its essentials — just the prompt, just the artifact.
+
+## When to Use
+
+Use Lean when you want the structured specify → plan → tasks → implement pipeline without the ceremony of the full templates. Each command produces a single focused Markdown file with no boilerplate sections to fill in.
+
+## Commands Included
+
+| Command | Output | Description |
+|---------|--------|-------------|
+| `speckit.specify` | `spec.md` | Create a specification from a feature description |
+| `speckit.plan` | `plan.md` | Create an implementation plan from the spec |
+| `speckit.tasks` | `tasks.md` | Create dependency-ordered tasks from spec and plan |
+| `speckit.implement` | *(code)* | Execute all tasks in order, marking progress |
+| `speckit.constitution` | `constitution.md` | Create or update the project constitution |
+
+## What It Replaces
+
+Lean overrides the five core workflow commands with self-contained prompts that produce each artifact directly — no separate template files involved. The result is a shorter, more direct workflow.
+
+## Installation
+
+```bash
+# Lean is a bundled preset — no download needed
+specify preset add lean
+```
+
+## Development
+
+```bash
+# Test from local directory
+specify preset add --dev ./presets/lean
+
+# Verify commands resolve
+specify preset resolve speckit.specify
+
+# Remove when done
+specify preset remove lean
+```
