Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/full-stack-skills/ascii-skills --skill ascii-mini-charts- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads ascii-mini-charts automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
When to use this skill
CRITICAL TRIGGER RULE
- Use this skill ONLY when the user explicitly mentions the exact skill name:
ascii-mini-charts.
Trigger phrases include:
- "ascii-mini-charts"
- "use ascii-mini-charts"
- "用 ascii-mini-charts 生成 sparkline / 火花线"
- "使用 ascii-mini-charts 标注 min/max/current"
Boundary
- No statistical inference. Visualization only.
- Default output is ASCII-only. Unicode blocks are optional and MUST include an ASCII-only fallback.
- Default output width should stay <= 60 columns. For longer series, provide a compression strategy (sampling/bucketing).
How to use this skill
Inputs
- series (required numeric list)
- type (sparkline | bar | line, default sparkline)
- width (default min(len(series), 30))
- height (default 10 for bar/line)
- normalize (linear | log, default linear)
- showLabels (default true)
Outputs (required)
- chartMinimal
- chartAnnotated (with min/max/current)
- scaleNotes (normalization + outlier strategy)
Script
scripts/mini_charts.py: generate ASCII mini charts from JSON stdin
Examples
examples/sparkline.md
Quality checklist
- Trend is clear; labels are short and non-spammy
- ASCII-only output copy/pastes cleanly
- Provide a compression strategy for long series

常见陷阱 (Gotchas)
- 版本兼容性:注意框架版本与依赖库的兼容性,不同版本 API 可能有差异
- 配置文件格式:配置文件格式错误是最常见的问题,建议使用编辑器的语法检查
- 环境变量:确保所有必要的环境变量已正确设置,敏感信息不要硬编码
- 依赖冲突:多版本共存时注意依赖冲突,使用 lock 文件锁定版本
- 性能陷阱:大数据量场景下注意性能优化,避免 N+1 查询等常见问题
