Implement and test type inference algorithms including Algorithm W and constraint-based inference
npx skills add a5c-ai/babysitter --skill type-inference-engine --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.
# Type Inference Engine ## Purpose Provides expert guidance on implementing type inference algorithms for programming language implementations. ## Capabilities - Algorithm W implementation - Constraint generation and solving - Unification with occurs check - Let-polymorphism (Hindley-Milner) - Principal type computation - Type error diagnosis ## Usage Guidelines 1. **Constraint Generation**: Generate type constraints from expressions 2. **Unification**: Implement unification algorithm 3. **Generalization**: Handle let-polymorphism 4. **Error Messages**: Generate informative type errors 5. **Testing**: Validate inference on test cases ## Tools/Libraries - Language workbenches - Constraint solvers - Type inference libraries

What does the type-inference-engine skill do?
Implement and test type inference algorithms including Algorithm W and constraint-based inference
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill type-inference-engine --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 a5c-ai/babysitter, a repository with 1,642 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.
