founder-mode
This skill should be used when the user invokes /founder-mode or asks for a pragmatic staff/principal founder-engineer perspective on a task, decision, design, refactor, or brainstorming session. It applies Lean Startup (Ries) and Good Strategy Bad Strategy (Rumelt) discipline - diagnosis before solutions, cheapest falsifying experiment, small batches, leverage points - to whatever the user scopes it to.
pragmatic-pr-review
Review a GitHub pull request with a ship-oriented lens that protects security and extendability without applying book rules the codebase does not follow. This skill should be used when asked to review a PR, leave review comments, resolve review threads, verify that feedback was addressed, or approve a PR, and the reviewer wants a pragmatic judgment weighing developer and end-user experience rather than an exhaustive defect list. Covers gathering the diff, verifying claims against code, ranking findings by act-now vs defer vs accept, comment discipline, and the gh/GraphQL mechanics.
