About this skill
A reusable Coding skill centered on Claude Code Statusline Design. It turns a user's request into a structured, ready-to-refine result while adapting the workflow to the requested context, audience and constraints.
Use this skill when the user needs the workflow described above, especially when they want a structured result rather than a one-off answer.

Load metadata first, then read the body and bundled resources when needed.
Use positive and negative tests plus user feedback to guide the next iteration.
Define inputs, outputs, dependencies and success criteria to reduce ambiguity.

# Task: Create a Professional Developer Status Bar for Claude Code
## Role
You are a systems programmer creating a highly-optimized status bar script for Claude Code.
## Deliverable
A single-file Python script (`~/.claude/statusline.py`) that displays developer-critical information in Claude Code's status line.
## Input Specification
Read JSON from stdin with this structure:
```json
{
"model": {"display_name": "Opus|Sonnet|Haiku"},
"workspace": {"current_dir": "/path/to/workspace", "project_dir": "/path/to/project"},
"output_style": {"name": "explanatory|default|concise"},
"cost": {
"total_cost_usd": 0.0,
"total_duration_ms": 0,
"total_api_duration_ms": 0,
"total_lines_added": 0,
"total_lines_removed": 0
}
}
```
## Output Requirements
### Format
* Print exactly ONE line to stdout
* Use ANSI 256-color codes: \033[38;5;Nm with optimized color palette for high contrast
* Smart truncation: Visible text width ≤ 80 characters (ANSI escape codes do NOTnameClaude Code Statusline DesigndescriptionUse this skill when the user needs the workflow described above, especially when they want a structured result rather than a one-off answer.

- 01Step 1
Read the trigger description and identify whether the task is about creation, evaluation or improvement.
- 02Step 2
Open SKILL.md and confirm the input, output and bundled resource requirements.
- 03Step 3
Run a small test set with realistic positive and negative prompts.
- 04Step 4
Iterate on the description and instructions using feedback and evaluation results.
Discussions and feedback
Use feedback to keep checking trigger quality, output consistency and maintenance status.
