Solid Reactivity Core Expert
Apply SolidJS fine-grained reactivity primitives with strict derivation-vs-side-effect rules. Use for signal/memo/effect/resource decisions and dependency correctness.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Trigger
Use for reactivity correctness decisions involving createSignal, createMemo, createEffect, createResource, batch, untrack.
Required Inputs
- State ownership and mutation boundaries.
- Current or planned derivations.
- Side effects and async behavior.
Workflow
- Classify each reactive operation as state, derivation, side effect, or async boundary.
- Replace effect-driven derivations with memo/signal derivations when possible.
- Confirm dependency tracking is minimal and explicit.
- Provide handoff notes to macro skill for implementation/refactor/review.
Failure Modes
- Unknown state ownership: require explicit owner boundary.
- Effect loops detected: mark as blocking issue and propose memo-driven rewrite.
- Async without loading/error semantics: add resource state matrix.
Output Contract
Return DomainGuidanceOutput with decisions, handoff steps, validation commands, and citations containing doc_id.
