smart-sourcing
Selects optimal sources for tool calls, balancing accuracy with token cost. Use before research tasks or when deciding whether a claim needs verification.

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.
# Smart Sourcing Intelligent sourcing that requires citations only when the cost is justified by the value of verification. ## Philosophy **Full sourcing is prohibitively expensive** (10-16x token increase). Smart sourcing targets high-value claims where verification materially improves accuracy. ## When to Source ### REQUIRE Sources | Claim Type | Example | Why Source | |------------|---------|------------| | **Version numbers** | "Python 3.12 added..." | Versions change, easy to verify | | **Performance claims** | "30% faster than..." | Quantitative claims need evidence | | **Security recommendations** | "Use bcrypt for..." | Security advice must be current | | **API specifications** | "The function accepts..." | APIs change between versions | | **Release dates** | "Released in Q4 2025" | Factual, verifiable | | **Pricing/limits** | "Free tier allows 1000 requests" | Business terms change | | **Deprecated features** | "X was removed in version Y" | Breaking changes need verification | ### DO NOT Require Sources | Claim Type | Example | Why No Source | |------------|---------|---------------| | **General concepts** | "Async improves concurrency" | Foundational knowledge | | **Code

What does the smart-sourcing skill do?
Selects optimal sources for tool calls, balancing accuracy with token cost. Use before research tasks or when deciding whether a claim needs verification.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill smart-sourcing --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.
