Product fitness and solution validation for bootstrapped founders. Assesses whether THIS specific solution is the right way to address a validated problem — value proposition clarity, solution-problem fit, minimum product achievability, differentiation reality, switching motivation, time-to-value, retention potential, and substitute vulnerability. Use when user runs `/solution-analysis`, asks abou

Use when you want to audit environment variable usage — scans the entire codebase for all env var references across all sources (code, Docker, CI, config files) and flags anything undocumented or inconsistent. Works for any stack and any env var pattern.

Use before committing or opening a pull request — reviews staged changes as a principal engineer for correctness, edge cases, and logic flaws. Always invoke this before creating a PR.

This skill coordinates the respo

Read or update project changelog. Use PROACTIVELY whenever you need context about what was done previously in ANY area of the codebase, and after making changes or decisions worth preserving. This is your strategic memory - use it liberally to avoid redoing work or missing context.

Analyze and recommend pricing structures and packaging options aligned with value delivery and business goals. Use this skill when a team needs to make or review pricing and packaging decisions.
