What Feasibility Test does

Feasibility Test runs a one-shot probe to check whether an unverified runtime, library, or external mechanism actually works as assumed. Use it before locking a design when the answer depends on live behavior.

Feasibility Test is cataloged under Quality on DirSkills. Feasibility Test comes from a repository tagged agentic, ai-agents, ai-coding-assistant, ai-development and ai-workflow.

Documentation

README

Excerpt

vc-feasibility-test

Output style: Follow process/development-protocols/communication-standards.md — answer-first, plain language, no unexplained jargon, TL;DR on long responses.

One-shot empirical probe skill. Used when SPEC or INNOVATE encounters an approach hinging on an unverified external/runtime/library mechanism — the question is "does this mechanism actually work the way the design assumes?", asked before the decision locks.

Boundary vs vc-test-coverage-plan

These two skills are complementary and must not be confused:
