Traction scoreGitHub stars can be faked, so popularity alone can be misleading. Traction Score looks for broader signs of recent attention, adoption, and active maintenance.
This skill provides a structured approach to reviewing code by anchoring analysis on the agreements between system participants. It focuses on correctness as the primary objective, treating performance and security as specific sub-cases of a broader verification engine.
It is designed for those auditing codebases or reviewing changes to ensure a fix is safe. The process requires forcing violating executions and refuting candidate bugs before they are reported, reducing noise in the review cycle.

Use the identify-assumptions-existing skill to stress-test [feature idea] for [existing product]. I will provide the product, objective, market segment, feature idea, and optionally a PRD, designs, or research. Identify Value, Usability, Viability, and Feasibility assumptions from Product Manager, Designer, and Engineer perspectives. For each assumption, state what could go wrong, confidence as High/Medium/Low, and a suggested test.
Prioritized backlog with estimates and acceptance criteria
Team roster and availability, including PTO, meetings, and on-call duties
Story-point velocity from the last three sprints
Sprint duration
Known dependencies or external owners
Use the sprint-plan skill to draft a sprint plan for [team or product]. Use the supplied prioritized backlog, team roster and availability, and velocity from the last three sprints. Reserve a 15–20% buffer, select only ready stories within capacity, map dependencies and the critical path, identify risks with mitigations, and produce a concise sprint goal and plan summary. Flag missing information instead of inventing it.
Use the marketing-ideas skill for [product]. Based on the product, target market, brand positioning, current channels, audience behavior, budget, and resource constraints I provide, generate five creative, cost-effective marketing ideas. For each, give the primary channel, core message, why it should engage this audience, and what makes it resource-efficient.
