What it does
The PoC skill is designed to help teams rapidly validate a technical approach or integration by defining explicit success criteria, limiting scope and duration, and focusing on high-risk areas to inform go/no-go decisions. It emphasizes throwaway code, a defined time box, and documentation of findings to support architectural choices.
How it works
The skill prescribes a structured PoC process: establish success criteria before coding, identify key risks, set a time-bound scope (with a defined PoC duration based on complexity), determine what to include and exclude, execute in phases (research, minimal setup, core implementation, testing against criteria, documentation), and capture findings with clear outcomes. It includes concrete phases for research, setup, core implementation, testing, and documentation, plus example PoC structures and evaluation templates. It also outlines anti-patterns to avoid, such as scope creep and productionizing PoCs.
When to use it
Use when evaluating new technologies or frameworks, validating technical approaches before committing, deciding architectural patterns with unknowns, testing third-party integrations, or demonstrating feasibility to stakeholders. It also distinguishes when not to use a PoC, such as when requirements are clear, the technology is familiar, or time pressure necessitates production work.
What it can touch
Contains guidance on using code to test hypotheses and measure outcomes, with references to creating a minimal repository structure and data for PoC demonstrations. It emphasizes non-production quality for PoC code and documents integration points and results.
Caveats
Emphasizes that PoCs should produce evidence to support a decision, not production-ready solutions. Recommends throwaway code, avoidance of feature completeness, and careful documentation of what worked, what didn’t, and remaining questions. No assurances beyond the stated success criteria, and practical time-boxing is essential to avoid scope creep.
# Proof of Concept (PoC) ## Core Principle **Prove the concept, not the implementation. Learn fast, decide faster.** Good PoCs: - **Have clear success criteria** — Know what you're validating - **Are time-boxed** — Days, not weeks - **Focus on risk** — Test what you're unsure about - **Lead to decisions** — Go/no-go with evidence - **Are disposable** — Code gets thrown away, knowledge doesn't --- ## When to Use Use this skill when: - Evaluating new technologies or frameworks - Validating technical approaches before committing - Making architectural decisions with unknowns - Testing third-party integrations - Demonstrating feasibility to stakeholders - De-risking major technical initiatives - Choosing between competing solutions Do NOT use a PoC when: - Requirements are clear and solution is known - Technology is already familiar to the team - Time pressure requires immediate production work - The problem is small enough to just solve directly --- ## PoC vs Prototype vs MVP ### Proof of Concept (PoC) - **Purpose**: Validate technical feasibility - **Audience**: Technical team - **Duration**: 1-5 days - **Quality**: Throwaway code - **Outcome**: Go/no-go decision ### Prototype - **Pu

What does the proof-of-concept skill do?
Rapid validation of technical feasibility and approach before full implementation. Use when evaluating new technologies, validating approaches, testing integrations, or demonstrating feasibility to stakeholders.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill proof-of-concept --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
