Porters Five Forces

phuryn/pm-skills
2.1k installs24.9k stars
Summary

This walks through Porter's Five Forces framework to analyze competitive dynamics in any industry. You get structured evaluation of competitive rivalry, supplier power, buyer power, threat of substitutes, and threat of new entrants, with clear criteria for rating each force as high, medium, or low. It's built for assessing market attractiveness before entering a space or when your competitive position shifts. The prompts push you to identify not just current state but trends and strategic responses. Pairs well with SWOT analysis when you need the full strategic picture, though forces analysis alone is often enough to spot whether you're fighting uphill.

improve

shadcn/improve

Survey any codebase as a senior advisor and produce prioritized, self-contained implementation plans for OTHER models/agents to execute. Strictly read-only on source code — never implements, fixes, or refactors anything itself. Use when asked to audit a codebase, find improvement opportunities (bugs, security, performance, test coverage, tech debt, migrations, DX), suggest features or where to take the project next (roadmap, product direction), or generate handoff plans for another agent to implement.
