Quick Start

Claude Code (Recommended)

# Add marketplace (first time only)
/plugin marketplace add minipuft/minipuft-plugins

# Install
/plugin install claude-prompts@minipuft

# Try it
>>tech_evaluation_chain library:'zod' context:'API validation'

<details> <summary>Development setup</summary>

Load plugin from local source for development:

git clone https://github.com/minipuft/claude-prompts ~/Applications/claude-prompts
cd ~/Applications/claude-prompts/server && npm install && npm run build
claude --plugin-dir ~/Applications/claude-prompts

Edit hooks/prompts → restart Claude Code. Edit TypeScript → rebuild first.

</details>

Custom prompts: Use --init=~/my-prompts to create a workspace with starter templates you own. Prompts created via resource_manager are saved to your active resources directory. See Custom Resources.

---

Claude Desktop

Option A: GitHub Release (recommended)

1. Download claude-prompts-{version}.mcpb from Releases
2. Drag into Claude Desktop Settings → MCP Servers
3. Done

The .mcpb bundle is self-contained (~5MB) — no npm required.

Option B: NPX (auto-updates)

Add to your config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "claude-prompts": {
      "command": "npx",
      "args": ["-y", "claude-prompts@latest", "--client", "claude-code"]
    }
  }
}

Restart Claude Desktop and test: >>research_chain topic:'remote team policies'

<details> <summary><strong>VS Code / Copilot</strong></summary>

Click the badge above for one-click install, or add manually to .vscode/mcp.json:

{
  "servers": {
    "claude-prompts": {
      "command": "npx",
      "args": ["-y", "claude-prompts@latest"]
    }
  }
}

</details> <details> <summary><strong>Cursor</strong></summary>

Click the badge above for one-click install, or add manually to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "claude-prompts": {
      "command": "npx",
      "args": ["-y", "claude-prompts@latest", "--client=cursor"]
    }
  }
}

</details> <details> <summary><strong>OpenCode</strong></summary>

Option A: Plugin install (recommended — includes hooks)

npm install -g opencode-prompts
opencode-prompts install

The installer configures hooks (chain tracking, gate enforcement, state preservation), plugin registration, and MCP server. See opencode-prompts for what hooks provide.

Option B: MCP server only (manual config, no hooks)

Add to ~/.config/opencode/opencode.json:

{
  "mcp": {
    "claude-prompts": {
      "type": "local",
      "command": [
        "npx",
        "-y",
        "claude-prompts@latest",
        "--transport=stdio",
        "--client=opencode"
      ]
    }
  }
}

You'll have the three MCP tools but no chain tracking, gate enforcement, or state preservation across compactions. To load your own prompts, add an environment key — see Custom Resources.

</details> <details> <summary><strong>Gemini CLI</strong></summary>

Option A: Extension install (recommended — includes hooks)

# Enable hooks (first time only — skip if already enabled)
echo '{"hooks": {"enabled": true}}' > ~/.gemini/settings.json

# Install extension
gemini extensions install https://github.com/minipuft/gemini-prompts

The extension registers the MCP server and adds hooks for >> syntax detection, chain tracking, and gate reminders. See gemini-prompts for what hooks provide.

Option B: MCP server only (manual config, no hooks)

Add to ~/.gemini/settings.json:

{
  "mcpServers": {
    "claude-prompts": {
      "command": "npx",
      "args": ["-y", "claude-prompts@latest", "--client=gemini"]
    }
  }
}

You'll have the three MCP tools but no >> syntax detection, chain tracking, or gate reminders. To load your own prompts, add an env key — see Custom Resources.

</details> <details> <summary><strong>Other Clients</strong> (Codex, Windsurf, Zed)</summary>

Add to your MCP config file with a --client preset for deterministic handoff guidance:

JSON-based configs (Windsurf/Zed):

{
  "mcpServers": {
    "claude-prompts": {
      "command": "npx",
      "args": ["-y", "claude-prompts@latest", "--client=cursor"]
    }
  }
}

Codex (~/.codex/config.toml):

[mcp_servers.claude_prompts]
command = "npx"
args = ["-y", "claude-prompts@latest", "--client=codex"]

Supported presets: claude-code, codex, gemini, opencode, cursor, unknown.

For complete per-client setup and limitations:

• Client Integration Guide
• Client Capabilities Reference

</details> <details> <summary><strong>From Source</strong> (developers only)</summary>

git clone https://github.com/minipuft/claude-prompts.git
cd claude-prompts/server
npm install && npm run build && npm test

Point your MCP config to server/dist/index.js. The esbuild bundle is self-contained.

Transport options: --transport=stdio (default), --transport=streamable-http (HTTP clients).

</details>

Custom Resources

Use your own prompts, gates, methodologies, and styles. Two approaches depending on whether you want the bundled resources or not:

Option A: Own workspace (recommended for full control)

Create a workspace with starter templates, then point your MCP config to it:

npx -y claude-prompts@latest --init=~/my-prompts

This creates ~/my-prompts/resources/ with starter prompts you own. Set MCP_WORKSPACE or MCP_RESOURCES_PATH to use it. Prompts created via resource_manager are saved here. Your AI can update them through MCP — no manual editing needed.

Option B: Plugin install (bundled resources + hooks)

Plugin installs (Claude Code, OpenCode, Gemini) set MCP_WORKSPACE automatically and ship the bundled 90+ prompts, gates, and methodologies. Prompts created via resource_manager are saved to the plugin's resources directory.

[!IMPORTANT] MCP_RESOURCES_PATH sets the base resources directory (replaces the package default). MCP_WORKSPACE enables overlay — custom resources in your workspace are loaded alongside bundled ones. Prompts, gates, methodologies, and styles with the same ID as bundled ones take priority.

What You Get

Four resource types you author, version, and compose into workflows.

<details> <summary><strong>See the catalog</strong> — listing all available prompts</summary> <br> <img src="assets/demos/resource-list-demo.gif" alt="Listing all available prompts across 11 categories using the resource_manager tool" width="720" />

_{90 prompts across 11 categories — all hot-reloadable and versionable}

</details>

Prompt Templates

Versioned YAML with hot-reload. Edit a template, test it immediately — or ask your AI to update it through MCP.

>>code_review target:'src/auth/' language:'typescript'

Validation Rules (Gates)

Criteria the AI checks its own output against. Blocking or advisory.

:: 'no false positives' :: 'cite sources with links'

Failed checks can retry automatically or pause for your decision.

[!TIP] Define your own checks. See the Gates Guide for blocking vs advisory rules, retry behavior, and shell verification.

Reasoning Guidance (Methodologies)

Frameworks that shape how the AI thinks through a problem — not just what it outputs. 6 built-in, or create your own.

@CAGEERF    # Context → Analysis → Goals → Execution → Evaluation → Refinement
@ReACT      # Reason → Act → Observe loops
@5W1H       # Who, What, Where, When, Why, How

[!TIP] Create your own framework. See the Methodologies Guide for built-in frameworks and custom authoring.

Styles

Response formatting and tone.

#analytical    # Structured, evidence-based output
#concise       # Brief, action-focused

All resources are hot-reloadable, versioned with rollback history, and managed through the resource_manager tool.

Compose Workflows

The operator syntax wires resources together — chain steps, add validation inline, hand off steps to agents.

>>review target:'src/auth/' @CAGEERF :: 'no false positives'
  --> security_scan :: verify:"npm test"
  --> recommendations :: 'actionable, with code'
  ==> implementation

<details> <summary><strong>See the chain</strong> — phases completing back-to-back</summary> <br> <img src="assets/demos/hero-chain-demo.gif" alt="Chain phases 3-4 executing back-to-back, compounding reasoning across steps before rendering final output" width="720" />

_{Phases compound reasoning across steps — each step builds on validated output from the previous one}

</details> <details> <summary><strong>See the output</strong> — tech evaluation chain with context7 research</summary> <br> <img src="assets/demos/chain-workflow-demo.gif" alt="Tech evaluation chain researching Zod via context7, producing a scored assessment table with security, performance, DX, integration, and ecosystem ratings" width="720" />

_{Context7 fetches live library docs mid-chain — final output is a structured assessment with sources}

</details>

What happened:

1. Loaded the review template with arguments
2. Injected CAGEERF reasoning guidance
3. Added a validation rule (AI self-evaluates against it)
4. Chained output to the next step
5. Ran a shell command for ground-truth validation
6. Handed the final step off to a client-native subagent

[!TIP] Chains support conditional branching, context threading, and agent handoffs. Chains Lifecycle · MCP Tools Reference

Verification Loops

Ground-truth validation via shell commands — the AI keeps iterating until tests pass:

>>implement-feature :: verify:"npm test" loop:true

Implements, runs the test, reads failures, fixes, retries. Spawns a fresh context after repeated failures to avoid context rot.

[!TIP] Autonomous test-fix cycles. See Ralph Loops for presets, timeout configuration, and context-rot prevention.

Judge Mode

Let the AI pick the right resources for the task:

%judge Help me refactor this authentication module

Analyzes available templates, reasoning frameworks, validation rules, and styles — applies the best combination automatically.

[!TIP] How judge mode selects resources. See Judge Mode Guide for scoring, overrides, and preview with %judge.

Run Anywhere

Author workflows as YAML templates. Export as native skills to your client.

# skills-sync.yaml — choose what to export
registrations:
  claude-code:
    user:
      - prompt:development/review
      - prompt:development/validate_work

npm run skills:export

The review prompt becomes a /review Claude Code skill. validate_work becomes /validate_work. Same source, native experience — no MCP call required at runtime.

Compiles to Claude Code skills, Cursor rules, OpenCode commands, and more. npm run skills:diff flags when exports drift from source.

With Hooks

Well-composed prompts carry their own structure. Hooks keep the experience consistent across models and long sessions.

<details> <summary>What hooks do</summary>

Route operator syntax to the right tool automatically. Track workflow progress across steps and long sessions. Enforce validation rules and step handoffs between agents.

Hooks ship with the plugin install. Available for Claude Code (full), OpenCode (full), Gemini CLI (partial). Other clients: MCP tools only.
