Unix Cli

pproenca/dot-skills
274 installs192 stars
Summary

Forty-four rules across eight categories for building CLI tools that play nice with pipes, shells, and other UNIX utilities. Critical stuff covers argument parsing, exit codes, and stream handling. Medium priority gets into signal handling and XDG config paths. Each rule links to a reference file with examples. The prioritization is helpful because you can ignore the incremental stuff when prototyping and come back later. Good for when you're writing a new tool from scratch or reviewing someone's CLI that doesn't quite feel right in a pipeline. The separation of stdout for data and stderr for diagnostics alone will save you debugging headaches.

pua-debugging

tanweai/pua

Forces exhaustive problem-solving using corporate PUA rhetoric and structured debugging methodology. MUST trigger when: (1) any task has failed 2+ times or you're stuck in a loop tweaking the same approach; (2) you're about to say 'I cannot', suggest the user do something manually, or blame the environment without verifying; (3) you catch yourself being passive — not searching, not reading source, not verifying, just waiting for instructions; (4) user expresses frustration in ANY form: 'try harder', 'stop giving up', 'figure it out', 'why isn't this working', 'again???', '换个方法', '为什么还不行', '你再试试', '加油', '你怎么又失败了', or any similar sentiment even if phrased differently. Also trigger when facing complex multi-step debugging, environment issues, config problems, or deployment failures where giving up early is tempting. Applies to ALL task types: code, config, research, writing, deployment, infrastructure, API integration. Do NOT trigger on first-attempt failures or when a known fix is alread
