How packages were screened

1. Source discoverySearched GitHub for pi.dev, pi-coding-agent, extension, commands, and skills; sorted by stars and recent activity.

2. Static inspectionCloned repos without installing. Scanned package scripts, shell/TS/JS/Python/JSON/Markdown for sudo, curl|bash, rm -rf, system writes, install hooks, token/secret handling, and shell spawning.

3. LabelingClean means no obvious risky patterns. Notes means expected power-tools behavior. Caution/review means inspect manually before installing globally.
