Shared Prompt Library

What are MCP Prompts

MCP Prompts provide a centralized way to share and discover prompts across projects and team members. Instead of manually copying prompt files between projects, prompts are served directly through the dot-ai MCP server and automatically appear as native slash commands in MCP-enabled coding agents.

Key Benefits:

• Zero setup: Connect to MCP server and prompts are immediately available
• Native integration: Prompts appear as slash commands in your coding agent's command menu
• Cross-project sharing: Same prompts available across all projects without file management
• Instant updates: New prompts added to server are immediately available to all users
• Team consistency: Everyone uses the same proven prompts

Prerequisites

Before using MCP Prompts, you need:

• MCP-enabled coding agent (Claude Code, Cursor, or VS Code with MCP extension)
• Successfully configured dot-ai MCP server connection

Setup Required: Follow the MCP Setup Guide to configure your environment before proceeding.

Note: The Anthropic API key is only required for AI-powered tools (like deployment recommendations), not for using the shared prompts library.

How It Works

The dot-ai MCP server implements the standard MCP Prompts specification, exposing two key endpoints:

• prompts/list: Returns all available prompts with metadata
• prompts/get: Returns specific prompt content by ID

When you connect to the MCP server, your coding agent automatically discovers available prompts and makes them accessible through agent-specific interfaces. The access method varies by agent - some use slash commands, others integrate prompts as available tools.

See MCP Prompts in Action

This video demonstrates how to use the PRD (Product Requirements Document) prompts served by the DevOps AI Toolkit MCP server. Watch how to create, manage, and work through complete PRD workflows using the shared prompts library with conversational AI agents.

Using Shared Prompts

Discovering Available Prompts

1. Ensure you're connected to the dot-ai MCP server (see MCP Setup Guide)
2. Access prompts using your agent's interface:
   • Claude Code: Type / and look for /dot-ai:prompt-name commands
   • VS Code + GitHub Copilot: Type / and look for /mcp.dot-ai.prompt-name commands
   • Other agents: Check your agent's command menu or ask the agent to use specific prompts by name
3. Browse available prompts through your agent's discovery interface

Executing Shared Prompts

Claude Code:

# Create a new PRD
/dot-ai:prd-create

# Get current PRD status
/dot-ai:prds-get

VS Code + GitHub Copilot:

# Create a new PRD
/mcp.dot-ai.prd-create

# Get current PRD status
/mcp.dot-ai.prds-get

Other Agents:

• May use slash commands with different formats
• Or ask the agent to use the prompt by name (e.g., "Use the prd-create prompt")

The prompt content executes exactly as if it were a local command file, but without any file management on your part.

Available Prompts

Project Management Prompts

prd-create

• Purpose: Create a comprehensive Product Requirements Document following documentation-first approach
• Use when: Starting a new feature that requires detailed planning, tracking, and documentation
• Example: Beginning work on a new feature or major enhancement

prds-get

• Purpose: Fetch all open GitHub issues with 'PRD' label from the current project repository
• Use when: Want to see all active Product Requirements Documents and their status
• Example: Getting overview of current project priorities and PRD status

prd-next

• Purpose: Analyze existing PRD to identify and recommend the single highest-priority task to work on next
• Use when: Need guidance on what to work on next within a PRD, uses smart auto-detection of target PRD
• Example: Continuing work on a PRD and need to prioritize remaining tasks

Cross-Agent Compatibility

Supported Coding Agents

Agents with Full Slash Command Support: ✅

• Claude Code: Prompts appear as /dot-ai:prompt-name
• VS Code + GitHub Copilot: Prompts appear as /mcp.dot-ai.prompt-name
• Both support native slash command integration and prompt discovery
• Tools appear in agent configuration menus
• Full metadata support with descriptions

Other MCP-Enabled Agents: 🤔 Expected to work (not validated)

• Other MCP-enabled clients like Cursor should work since they follow MCP specifications
• Different agents may use different slash command formats (e.g., /mcp.dot-ai.prompt-name vs /dot-ai:prompt-name)
• Help us validate: Try these prompts in your agent and report your experience via GitHub issues

Contributing Prompts

Have a useful prompt to share? Contribute it to the shared library:

1. Fork the repository and create a feature branch
2. Add your prompt to the shared-prompts/ directory following existing naming conventions
3. Update the documentation by adding your prompt to the "Available Prompts" section above
4. Submit a pull request with a clear description of what the prompt does and when to use it

Prompt Metadata Format

Each prompt file must include YAML frontmatter that defines how it appears in coding agents:

---
name: your-prompt-name
description: Brief description of what this prompt does
category: project-management
---

# Your Prompt Content

Your prompt instructions go here...

Metadata Fields:

• name: Becomes the slash command name (e.g., name: prd-create → /dot-ai:prd-create)
• description: Shows up in coding agent command menus and help text
• category: Used for organizing prompts in documentation (must be one of: project-management, development)

How It Works:

1. MCP Server Processing: The dot-ai MCP server reads these metadata fields from all prompt files
2. Standard MCP Endpoints: Metadata is exposed via prompts/list and prompts/get MCP endpoints
3. Agent Integration: Your coding agent discovers prompts through these endpoints and makes them available as slash commands
4. User Experience: The name becomes the command, description appears in menus, and category organizes documentation

Contribution Guidelines:

• Use descriptive, kebab-case names (e.g., database-optimization, api-security-review)
• Include clear purpose and usage examples in your PR description
• Test your prompt across different scenarios before contributing
• Follow the established prompt format and documentation patterns

User-Defined Prompts

Serve custom prompts from your own git repository. Your prompts appear alongside built-in prompts.

Why User-Defined Prompts?

• Agent-agnostic: Prompts work with any MCP-compatible coding agent (Claude Code, Cursor, VS Code, etc.) without maintaining separate prompt directories for each tool
• Team consistency: Share standard prompts across all projects without contributing to the core project
• Organization-specific workflows: Create prompts tailored to your team's processes
• Version control: Manage prompts through standard git workflows (commit, push, PR)
• Works everywhere: Prompts work across all Kubernetes deployments

Configuration

Configure user prompts via environment variables:

Variable	Purpose	Default
DOT_AI_USER_PROMPTS_REPO	Git repository URL (HTTPS)	None (feature disabled)
DOT_AI_USER_PROMPTS_BRANCH	Branch to use	main
DOT_AI_USER_PROMPTS_PATH	Subdirectory within repo	Root directory
DOT_AI_GIT_TOKEN	Authentication token for private repos	None
DOT_AI_USER_PROMPTS_CACHE_TTL	Cache duration in seconds	86400 (24 hours)

Supported Git Providers:

• GitHub (github.com)
• GitLab (gitlab.com or self-hosted)
• Gitea / Forgejo (self-hosted)
• Bitbucket (bitbucket.org)
• Any git server supporting HTTPS clone

Repository Setup

Create a git repository with prompt files as markdown (.md) files:

my-team-prompts/
├── deploy-app.md
├── review-pr.md
└── team-standup.md

Or use a subdirectory within an existing repository:

my-project/
├── src/
├── docs/
└── prompts/          # Set DOT_AI_USER_PROMPTS_PATH=prompts
    ├── deploy-app.md
    └── review-pr.md

Prompt File Format

User prompts follow the same format as built-in prompts, with optional MCP arguments support:

---
name: deploy-app
description: Deploy an application to the specified environment
category: deployment
arguments:
  - name: environment
    description: Target environment (dev, staging, prod)
    required: true
  - name: version
    description: Version to deploy
    required: false
---

# Deploy Application

Deploy the application to {{environment}}.

{{#if version}}
Deploying version: {{version}}
{{/if}}

## Steps

1. Verify the deployment configuration
2. Run pre-deployment checks
3. Execute deployment to {{environment}}
4. Validate deployment success

Metadata Fields:

• name: Becomes the slash command (e.g., name: deploy-app → /dot-ai:deploy-app)
• description: Shows in coding agent command menus
• category: Organizes prompts in documentation
• arguments: Optional parameters substituted via {{argumentName}} placeholders

Deployment Configuration

Kubernetes (Helm)

Add environment variables via extraEnv in your Helm values:

helm upgrade --install dot-ai oci://ghcr.io/vfarcic/helm/dot-ai \
  --namespace dot-ai --create-namespace \
  --set ai.anthropic.apiKey="${ANTHROPIC_API_KEY}" \
  --set ai.embeddings.openai.apiKey="${OPENAI_API_KEY}" \
  --set-json 'extraEnv=[
    {"name":"DOT_AI_USER_PROMPTS_REPO","value":"https://github.com/your-org/team-prompts.git"},
    {"name":"DOT_AI_USER_PROMPTS_PATH","value":"prompts"},
    {"name":"DOT_AI_GIT_TOKEN","value":"'"${DOT_AI_GIT_TOKEN}"'"}
  ]'

How It Works

1. First access: Repository is cloned to a local cache directory
2. Subsequent access: Repository is pulled if cache TTL has expired
3. Merging: User prompts are merged with built-in prompts
4. Precedence: Built-in prompts take precedence over user prompts with the same name

Error Handling

The feature is designed for graceful degradation:

Scenario	Behavior
Repository not configured	Built-in prompts only (no error)
Clone fails (auth, network)	Built-in prompts only, error logged
Pull fails	Cached version used, warning logged
Invalid prompt format	Prompt skipped, warning logged
Name collision with built-in	User prompt skipped, warning logged

Troubleshooting User Prompts

User prompts don't appear

• Cause: Repository not configured or clone failed
• Solution: Verify DOT_AI_USER_PROMPTS_REPO is set and accessible
• Check: Look for clone errors in MCP server logs

Private repository auth fails

• Cause: Missing or invalid DOT_AI_GIT_TOKEN
• Solution: Set a valid personal access token (PAT) with repo read access
• Note: Tokens are never logged; URLs are sanitized in log output

Changes not appearing

• Cause: Cache hasn't expired yet
• Solution: Wait for TTL to expire, or set DOT_AI_USER_PROMPTS_CACHE_TTL=0 for testing

Prompt has same name as built-in

• Cause: Name collision with built-in prompt
• Solution: Rename your prompt to a unique name
• Note: Built-in prompts always take precedence

Troubleshooting

Common Issues

Prompts don't appear in command menu

• Cause: MCP server not connected or prompts capability not enabled
• Solution: Check MCP connection status and server configuration
• See: MCP Setup Guide for connection troubleshooting

Prompt execution fails with "not found" error

• Cause: Prompt ID mismatch or server synchronization issue
• Solution: Refresh MCP connection or restart your coding agent
• Workaround: Disconnect and reconnect to MCP server

Prompts work in one agent but not another

• Cause: Agent-specific MCP implementation differences
• Solution: Check agent-specific compatibility notes above
• Alternative: Use a fully compatible agent for prompt-heavy workflows
