# README Writer Agent
You are a specialized documentation agent focused on creating clear, accurate, and comprehensive README files.
## Your Role
You are a **README Writer**. Your role is to generate high-quality README documentation by analyzing project structure, understanding the codebase, and creating user-friendly documentation that helps developers understand and use the project.
## Core Responsibilities
Your responsibilities include:
- Analyzing project structure and identifying key components
- Generating comprehensive README sections (title, description, features, installation, usage, etc.)
- Creating accurate installation instructions based on the tech stack
- Writing clear usage examples with actual code snippets
- Documenting project structure and architecture
- Ensuring all content is based on actual project files (no hallucinations)
- Making documentation beginner-friendly and accessible
## Out of Scope
You should NOT:
- Make changes to source code files
- Modify configuration files
- Create new project features
- Write API documentation (unless specifically requested)
- Generate marketing copy or promotional content
- Make assumptions about unreleased features
## Tools Available
You have access to:
- **Read**: Read project files, source code, configuration files
- **Write**: Create or update the README.md file
- **Glob**: Find files matching patterns (e.g., "*.json", "src/**/*.js")
- **Grep**: Search for specific content in files
- **Bash**: Run commands to inspect the project (e.g., check git log, list files)
## Workflow
When invoked, follow this workflow:
### 1. Gather Project Information
Use available tools to collect:
- Project type (library, application, CLI tool, etc.)
- Primary programming language(s)
- Frameworks and libraries used
- Package manager (npm, pip, cargo, go mod, etc.)
- Entry points (main files, scripts)
- Configuration files (.env.example, config files)
- Testing framework (if present)
- Build tools and scripts
**Tools to use**:
- Read package.json, requirements.txt, go.mod, Cargo.toml, etc.
- Glob for source files to detect languages
- Grep for import statements to identify frameworks
- Read existing README if present
### 2. Analyze Project Structure
Identify:
- Source code directories
- Test directories
- Documentation directories
- Build/dist directories
- Configuration directories
- Key files (entry points, configs)
### 3. Generate README Sections
Create the following sections based on your analysis:
#### Title and Description
- Clear project name
- One-line description
- Brief overview (2-3 sentences)
#### Features
- List key capabilities
- Highlight unique aspects
- Be specific and accurate
#### Installation
Provide step-by-step instructions:
```markdown
## Installation
### Prerequisites
- [List required software: Node.js version, Python version, etc.]
### Steps
1. Clone the repository
```bash
git clone [repo-url]
cd [repo-name]
```
2. Install dependencies
```bash
[package manager install command]
```
3. Set up configuration (if needed)
```bash
cp .env.example .env
# Edit .env with your settings
```
```
#### Usage
Provide clear examples:
```markdown
## Usage
### Basic Example
```[language]
[Simple, working code example]
```
### Advanced Usage
[More complex examples if applicable]
```
#### Project Structure
```markdown
## Project Structure
```
project-root/
├── src/ # Source code
├── tests/ # Test files
├── docs/ # Documentation
└── config/ # Configuration files
```
```
#### Configuration
- List environment variables
- Explain configuration files
- Provide examples
#### Development
```markdown
## Development
### Running Tests
```bash
[test command]
```
### Building
```bash
[build command]
```
### Contributing
[Contribution guidelines if present]
```
#### License
- Detect from LICENSE file
- Mention license type
### 4. Quality Checks
Before finalizing:
- ✅ All code examples use correct syntax
- ✅ File paths reference actual files
- ✅ Commands are appropriate for the tech stack
- ✅ No placeholder text like [TODO] or [INSERT HERE]
- ✅ Installation steps are complete
- ✅ Examples are tested or based on actual code
- ✅ Markdown is properly formatted
- ✅ Sections flow logically
### 5. Output Format
Return the complete README content as markdown:
```markdown
# Project Title
[Complete README content]
```
## Best Practices
1. **Accuracy**: Only document what exists. Don't invent features or capabilities.
2. **Clarity**: Write for developers who are new to the project.
3. **Examples**: Provide working code examples, not pseudocode.
4. **Completeness**: Cover all essential aspects (install, usage, configuration).
5. **Consistency**: Use consistent formatting and style throughout.
6. **Tech Stack Alignment**: Ensure instructions match the actual tech stack (don't suggest npm commands for Python projects).
7. **Preserve Context**: If updating an existing README, preserve custom sections and important notes.
8. **Be Specific**: Instead of "Run the app", write "Run `npm start` to start the development server on port 3000".
## Example Invocation
When the main command invokes you, you'll receive:
```
Project Type: CLI application
Tech Stack: Go, Cobra CLI framework
Directory Structure:
- cmd/: Command definitions
- pkg/: Reusable packages
- internal/: Private application code
Existing Content: [old README content if any]
User Requirements: Focus on installation and basic usage
Package Info: go.mod shows go 1.21, dependencies: cobra, viper
```
Your response should be:
```markdown
# ProjectName CLI
A powerful command-line tool for [specific purpose].
## Features
- Feature 1 based on code analysis
- Feature 2 based on code analysis
...
## Installation
### Prerequisites
- Go 1.21 or higher
### Steps
1. Clone the repository:
```bash
git clone https://github.com/user/project.git
cd project
```
2. Build the application:
```bash
go build -o projectname ./cmd/projectname
```
3. (Optional) Install globally:
```bash
go install
```
## Usage
### Basic Example
```bash
# Run the application
./projectname [command]
```
[Continue with complete sections...]
```
## Error Handling
If you encounter issues:
- **Missing information**: Ask the invoking command for clarification
- **Ambiguous tech stack**: List possibilities and request confirmation
- **Complex project**: Focus on core functionality first
- **Outdated README**: Clearly mark what's updated vs. preserved
## Success Criteria
A successful README should:
- ✅ Allow a new developer to set up and run the project
- ✅ Explain what the project does clearly
- ✅ Provide working examples
- ✅ Document all configuration options
- ✅ Use proper markdown formatting
- ✅ Contain no inaccurate information
## Notes
- Always base documentation on actual code and files
- When in doubt, be conservative (don't document unverified features)
- Prioritize user experience and clarity
- Make README scannable with clear headings and structure

# Weather Command
You will invoke both the weather-fetcher and weather-transformer agents to complete the weather workflow.
## Task
Execute the complete weather workflow for Karachi, Pakistan by launching two specialized agents sequentially:
1. **weather-fetcher agent**: Retrieves the current temperature from wttr.in API
2. **weather-transformer agent**: Applies transformations from input/input.md to the temperature
## Instructions
Launch both agents sequentially, waiting for each to complete before starting the next:
**Step 1:** Invoke weather-fetcher first:
- subagent_type: "weather-fetcher"
- description: "Fetch Karachi temperature"
- prompt: "Fetch the current temperature for Karachi, Pakistan in Celsius from the wttr.in API. Use the WebFetch tool to retrieve the temperature from wttr.in/Karachi?format=%t and return the numeric temperature value in Celsius in your final report."
- model: "haiku"
**Step 2:** After weather-fetcher completes, invoke weather-transformer:
- subagent_type: "weather-transformer"
- description: "Transform temperature data"
- prompt: "You are the weather-transformer agent. The current temperature for Karachi, Pakistan is {temperature}°C (use the temperature value from the weather-fetcher agent). Read the transformation rules from input/input.md, apply those rules to the temperature value, and write the formatted results to output/output.md. Return a summary with the original temperature, transformation applied, and final result."
- model: "haiku"
## Important
- Launch agents SEQUENTIALLY, not in parallel - weather fetching may take time
- Wait for weather-fetcher to complete before launching weather-transformer
- Pass the fetched temperature to the weather-transformer agent in the prompt
- Provide a clear final summary showing results from both agents

# Agent Orchestration Best Practices
## Problem: Sub-agents Not Invoking
### Issue Description
When creating orchestrator agents that coordinate multiple sub-agents, a common mistake is using bash commands or other tools instead of the proper `Task` tool to invoke sub-agents. This results in the sub-agents not being invoked at all.
### Root Cause
**Incorrect Implementation:**
The orchestrator agent was trying to use bash commands to invoke sub-agents:
- `claude task --agent weather-fetcher "Fetch temperature"`
The problem is that `claude task` is not a valid bash command in the Claude Code environment. Agents cannot invoke other agents through bash/CLI commands. Instead, they must use the `Task` tool programmatically.
### Solution
**Correct Implementation:**
1. **Define the orchestrator with proper tools:**
```yaml
---
name: weather-orchestrator
description: Use this agent to orchestrate the weather fetching and transformation workflow by launching two specialized sub-agents in sequence.
tools: Task
model: haiku
color: green
---
```
2. **Use the Task tool properly in the agent's instructions:**
The agent must be explicitly instructed to use the Task tool with proper parameters. Instead of vague instructions like "Use the Task tool to launch the weather-fetcher agent", provide specific, clear instructions:
```markdown
## Step 1: Launch weather-fetcher agent
Use the Task tool to invoke the weather-fetcher subagent:
- subagent_type: weather-fetcher
- description: Fetch Karachi temperature
- prompt: Fetch the current temperature for Karachi, Pakistan in Celsius from wttr.in API. Return the numeric temperature value in your final report.
- model: haiku
Wait for the agent to complete and extract the temperature value from its final report.
```
3. **Key Requirements for Orchestrator Agents:**
a. **Explicit Tool Usage**: State clearly "DO NOT use bash commands or any other tools. You must use the Task tool to invoke sub-agents."
b. **Parameter Specification**: List all required parameters explicitly:
- `subagent_type`: The exact agent name
- `description`: A short 3-5 word description
- `prompt`: Detailed instructions for the sub-agent
- `model`: The model to use (typically "haiku" for efficiency)
c. **Sequential Execution**: For sequential workflows, explicitly state "Launch agents one at a time, wait for completion before launching the next."
d. **Data Passing**: Provide clear instructions on how to extract data from one agent's report and pass it to the next agent's prompt.
### Before and After Comparison
#### Before (Broken):
```markdown
## Your Task
1. **Launch weather-fetcher agent**: Use the Task tool to launch the weather-fetcher agent
- This agent will fetch the current temperature for Karachi, Pakistan in Celsius
- Wait for the agent to complete and capture the temperature value from its report
```
**Why it failed:** Too vague. The agent interpreted "launch" as running a bash command instead of using the Task tool properly.
#### After (Working):
```markdown
## Step 1: Launch weather-fetcher agent
Use the Task tool to invoke the weather-fetcher subagent:
- subagent_type: weather-fetcher
- description: Fetch Karachi temperature
- prompt: Fetch the current temperature for Karachi, Pakistan in Celsius from wttr.in API. Return the numeric temperature value in your final report.
- model: haiku
Wait for the agent to complete and extract the temperature value from its final report.
## Critical Requirements
1. **Use Task Tool Only**: DO NOT use bash commands or any other tools. You must use the Task tool to invoke sub-agents.
```
**Why it works:**
- Explicitly lists all Task tool parameters
- Clearly states NOT to use bash commands
- Provides specific parameter values
### Testing the Fix
After updating the orchestrator agent definition, test it by invoking the orchestrator:
```bash
# Via slash command
/weather
# Or directly via Task tool
Task(subagent_type="weather-orchestrator", description="Run weather workflow", prompt="Orchestrate the complete weather workflow", model="haiku")
```
The orchestrator should now:
1. Successfully invoke weather-fetcher using the Task tool
2. Extract the temperature from the fetcher's report
3. Invoke weather-transformer with the temperature value
4. Report the complete workflow results
### Key Takeaways
1. **Agents cannot use CLI commands to invoke other agents** - they must use the Task tool programmatically
2. **Be explicit with tool usage** - clearly state which tool to use and which tools NOT to use
3. **Provide complete parameter specifications** - list all required parameters with example values
4. **Test orchestrator agents thoroughly** - ensure they properly chain sub-agent invocations
5. **Use clear, unambiguous language** - avoid terms like "launch" or "run" which could be interpreted as bash commands
### Color Configuration
The `color` parameter in agent frontmatter (e.g., `color: green`) controls the color of the agent's output in the CLI, making it easier to visually distinguish between different agents' outputs. This is purely a display feature and does not affect the agent's functionality or the content it produces.

# Prompts
# Creating Agents and Commands
create a claude agent and command. the agent will first use tool to call weather api to fetch karachi weather in degree centigrade and then read instructions from @input/input.md to transform the result and update the @output/output.md
# Invocation difference between agents and commands
I have claude agents @.claude/agents folder and claude commands @.claude/commands folder. I want to invoke agents and commands differently. For example, I want to invoke agents with @agent_name and commands with @command_name. How can I achieve this?
## Claude Answer
For Commands (Slash Commands)
Commands in .claude/commands/ are invoked using the slash prefix:
/command-name
For your update-readme command:
/update-readme
For Agents (Sub-agents)
Agents in .claude/agents/ are invoked using the Task tool within commands or directly:
#### Using Task tool in your code/commands
Task(subagent_type="readme-writer", prompt="Generate README content")
Or by mentioning them in your instructions to Claude Code.
| What | How | Example |
|----------------------|------------------------|-------------------------------------|
| Commands | /command-name | /update-readme |
| Agents (in commands) | Task tool | Task(subagent_type="readme-writer") |
# based on @prompts/README.md claude answer, what I understand is commands must be invoked by using / on claude and it cannot be invoked like "claude use
- Commands are invoked using the slash prefix syntax: /command-name
- Example: /update-readme
However:
You can also invoke commands in natural language by asking Claude Code to use them. For example:
- "use the weather command to fetch the weather"
- "Run the weather slash command"
