30-SECOND BRIEF
What it does—and when it fits
Prototype creates throwaway code to answer one design or logic question. The upstream Skill chooses between an interactive logic/state prototype and several switchable UI directions, keeps setup minimal, exposes state after actions, and expects validated decisions to be captured before the prototype is deleted or folded into production code.
INSTALL BY AGENT
Choose your Agent
Paths come from official Agent docs or the universal installer behind skills.sh. Compatibility still follows this Skill's record.
.claude/skills/prototype/~/.claude/skills/prototype/Use project scope for team sharing and personal scope across repositories. The installer defaults to project scope; add -g for personal scope.
npx skills add mattpocock/skills --skill prototype --agent claude-codeClaude Code discovers custom Skill folders automatically at project or personal scope.

A practical workflow
Test a state model
Build a small interactive harness for difficult logic transitions.
Compare UI directions
Put meaningfully different visual options on one switchable route.
Capture the verdict
Record what the prototype proved before cleanup or production work.
THE TRADEOFFS
Advantages and tradeoffs
Notable strengths
- This profile is manually organized around the current upstream SKILL.md workflow.
- The capability boundary remains explicitly tied to mattpocock/skills.
- Core uses, limitations, and risks are separated for pre-install review.
Limitations
- Prototype code intentionally omits production hardening, persistence, and broad edge-case coverage.
- A convincing demo can still validate the wrong question if the initial branch is chosen poorly.
BEST FIT
Who it is for
Product teams resolving uncertain interactions
Engineers testing state or interface decisions
BEFORE YOU USE IT
Risks to review before use
Prototype promoted to production
Throwaway shortcuts can become permanent. Label the artifact clearly and require a separate production review.
Upstream instruction drift
Behavior can change with upstream updates. Record the commit used for important workflows and review updates before adoption.
SECURITY
What the permission profile means
- Declared access remains governed by the current upstream SKILL.md and runtime requests.
- Treat repository files, web content, and tool output as untrusted input.
- SkillSignal has not independently executed or security-audited this package; external skills.sh labels are not SkillSignal certification.
Not a security certification. External ratings are attributed references. SkillSignal has not independently executed or security-reviewed this Skill.
