prove-your-worth
Ruthlessly audit project features for justification. Challenge every feature to prove its value with evidence or face removal. Uses MCP tools for research.
npx skills add majiayu000/claude-skill-registry --skill prove-your-worth --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Prove Your Worth — Feature Justification Audit ## Philosophy > "Every line of code is a liability. Every feature is technical debt until proven otherwise." This skill embodies extreme pragmatism: - **Existence is not justification** — Features must earn their place - **External is often better** — Well-maintained OSS beats custom code - **Simpler is superior** — Complexity requires compelling justification - **Facts over feelings** — No "we might need this" or "it's cool" ## When to Use - Before major architectural decisions - When codebase feels bloated or unfocused - When onboarding reveals "why do we have this?" - Before starting new features (to clean first) - Periodically (quarterly feature audit) ## MCP Tools Required This skill leverages MCP tools for evidence-based research. If MCP is unavailable, findings will be limited to agent knowledge (clearly marked). | Tool | Provider | Purpose | |------|----------|---------| | `brave_web_search` | brave-search | Find alternative solutions, compare tools | | `get_library_docs` | context7 | Get documentation for potential replacements | | `search_repositories` | github | Find similar OSS implementations | | `get_readme` | github |

What does the prove-your-worth skill do?
Ruthlessly audit project features for justification. Challenge every feature to prove its value with evidence or face removal. Uses MCP tools for research.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill prove-your-worth --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.
