Configures and customizes Claude Code statuslines with multi-line layouts, cost tracking via ccusage, git status indicators, and customizable colors. Activates for statusline setup, installation, configuration, customization, color changes, cost display, git status integration, or troubleshooting statusline issues.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong description that clearly defines a narrow domain (Claude Code statusline configuration), lists specific capabilities, and provides explicit activation triggers. It uses proper third-person voice and covers both what the skill does and when it should be used. The trigger terms are natural and comprehensive.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: configuring multi-line layouts, cost tracking via ccusage, git status indicators, and customizable colors. These are detailed, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both 'what' (configures statuslines with multi-line layouts, cost tracking, git status, colors) and 'when' with explicit triggers ('Activates for statusline setup, installation, configuration, customization, color changes, cost display, git status integration, or troubleshooting'). | 3 / 3 |
Trigger Term Quality | Includes strong natural trigger terms users would say: 'statusline', 'cost tracking', 'ccusage', 'git status', 'color changes', 'customization', 'troubleshooting statusline issues'. Good coverage of variations. | 3 / 3 |
Distinctiveness Conflict Risk | Very specific niche — Claude Code statusline configuration is a narrow, well-defined domain. Terms like 'statusline', 'ccusage', and 'multi-line layouts' are highly distinctive and unlikely to conflict with other skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured skill with strong actionability and good progressive disclosure. The main weaknesses are moderate verbosity (some sections explain things Claude doesn't need explained, like the benefits of multi-line layouts) and missing validation checkpoints in the installation workflow. The troubleshooting section is practical and well-organized.
Suggestions
Add a validation step after installation (e.g., 'Verify: restart Claude Code and confirm the 3-line statusline appears') to improve workflow clarity.
Trim the 'When to Use This Skill' section and the 'Benefits' list under Multi-Line Layout — these explain things Claude can infer and consume tokens without adding actionable value.
Move the full color scheme listing (all ANSI codes) to references/color_codes.md since it's already referenced there, keeping only 1-2 examples inline.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill includes some unnecessary explanation (e.g., 'Benefits' list for multi-line layout, 'When to Use This Skill' section that restates the description). The color scheme section listing all ANSI codes inline could be trimmed since it references color_codes.md. However, most content is reasonably efficient. | 2 / 3 |
Actionability | Provides concrete, executable bash commands and code snippets throughout — installation steps, specific printf modifications for color changes and layout conversion, troubleshooting commands like `which ccusage` and `ls -lh /tmp/claude_cost_cache_*.txt`. Examples are copy-paste ready with real ANSI codes. | 3 / 3 |
Workflow Clarity | Installation steps are clearly sequenced, but there are no validation checkpoints — no step to verify the statusline is working after installation, no verification that settings.json was correctly updated, and no feedback loop for the manual installation process. For a skill that modifies config files, validation steps would be important. | 2 / 3 |
Progressive Disclosure | Excellent structure with a Quick Start section followed by detailed features, customization, and troubleshooting. References to external files (color_codes.md, ccusage_integration.md) are clearly signaled and one level deep. The Resources section at the end provides a clean directory of supporting files. | 3 / 3 |
