+## Core Differences Between Commands and Agents
+
+While commands and agents share similar invocation patterns, they have fundamental architectural differences:
+
+### Key Architectural Differences
+
+**1. Purpose & Complexity**
+- **Commands**: Reusable prompt templates that expand into instructions. Best for **procedural workflows** with predefined steps.
+- **Agents**: Autonomous subprocesses with their own tool access. Best for **complex, multi-step tasks** requiring independent decision-making.
+
+**2. Execution Model**
+- **Commands**: Expand into prompts that Claude executes in the main conversation context
+- **Agents**: Run as separate subprocesses with isolated execution environments
+
+**3. Tool Access**
+- **Commands**: Execute within the main Claude context and inherit available tools
+- **Agents**: Have explicitly defined tool subsets specified in their configuration (e.g., `tools: Read, Grep, Bash`)
+
+**4. Autonomy Level**
+- **Commands**: Provide instructions for Claude to follow. Can interact with users via AskUserQuestion tool to gather preferences or clarify requirements.
+- **Agents**: Act autonomously to complete tasks and return final reports. **Should NOT ask questions** - they run independently and must work with the information provided in their prompt.
+
+**5. Model Selection**
+- **Commands**: Can specify which model to use for executing the command
+- **Agents**: Can specify which model runs the agent subprocess (e.g., `model: haiku` for cost efficiency)
+
+### When to Choose Each
+
+**Choose Commands when:**
+- You have a reusable prompt/workflow
+- Steps are mostly predefined
+- You want users to trigger via `/slash` syntax
+- You need a simple procedural template
+
+**Choose Agents when:**
+- Task requires autonomous multi-step problem solving
+- You need isolated tool access for security/organization
+- Task should run as independent subprocess
+- You want specialized capabilities (like code review, test running)
+
+**Example from this repository:**
+- `/weather-karachi` command: Orchestrates the workflow
+- `weather-fetcher` agent: Autonomous subprocess that fetches temperature
+- `weather-transformer` agent: Autonomous subprocess that transforms data
+
+The command coordinates, while agents execute their specialized tasks independently.

 # Weather Transformation Results
 
-**Original Temperature:** 26°C
+**Original Temperature:** 309.15 K (Kelvin)
+
+**Conversion to Celsius:** 309.15 K - 273.15 = 36°C
 
 **Transformation Applied:** Add +10 to the result
 
-**Final Result:** 36°C
+**Calculation:** 36°C + 10 = 46°C
+
+**Final Result in Celsius:** 46°C
+
+**Final Result in Kelvin:** 319.15 K
+
+## Detailed Summary
+
+- Input: 309.15 K
+- Intermediate (Celsius): 36°C
+- After Transformation: 46°C
+- Output: 319.15 K
 
 ## Calculation Details
 
-- Starting value: 26°C
-- Operation: +10
-- Result: 26 + 10 = 36°C
+- Starting value: 309.15 K (equal to 36°C)
+- Operation: Add +10
+- Result: 36 + 10 = 46°C (equal to 319.15 K)
