# Assess LWC to widget fit

Answer two questions for each LWC: **Can the current behavior be represented?** If not, **would a feasible widget still accomplish the user's goal?** Assess only; do not create metadata. A widget is its own declarative artifact, distinct from a Lightning Type. Its body renders supplied data with discovered tiles, bindings, formulas, and supported actions. It cannot run arbitrary LWC code, fetch after render, or retain reactive client state.

## Evidence and decision

1. Read the component's JS/TS, template, metadata, and relevant child components. State the user's goal in one sentence. Trace each visible value to its source and identify interactions essential to that goal. An `@api` property proves external input, **not** that an invocable action returns it. A user's explicit statement about action output is evidence for a feasibility assessment; verify the actual action contract and Lightning Type/renderer wiring before claiming a working migration.
2. Map the **job** of each rendered element and action to the target surface. `platform-widget-generate` explains the discovery procedure; the actual `discoverUiComponents` response and `getUiComponentSchemas` results establish available blocks and attributes. Read its `references/widget-formulas.md` only when a transformation matters. Record the target channel from evidence rather than assuming a fixed channel or tile count. Without discovery, a documented pattern can support a **provisional candidate**, but absence from examples does not prove a block is unavailable. Use `review` when that uncertainty determines the verdict; never invent a tile, action, input submission mechanism, or formula.
3. Check all dimensions, even after a failure: rendering vocabulary; retained state, imperative effects, and actions; data origin; and transformations. A bounded snapshot or pre-shaped collection can sometimes move into the invocable action's output. Inspect the action implementation before asserting that it can. A formula's scalar `MIN`/`MAX`, date, or regex support does not imply collection sorting or aggregation. Input forms require evidence that the current tiles can collect values **and** pass those values to an action; `sendMessage` alone does not prove that.
4. Judge the current LWC and a proposed widget separately. A link or `sendMessage` may preserve an intent without preserving the original interaction, if the agent can actually perform the requested work with the required context. A carousel may become a product list; an order builder whose purpose is choosing quantities may not. Treat that change as a rebuild. For the widget candidate, consider a **specified proposed IA contract** when setting `rendersAsWidget`; state the contract change explicitly. If feasibility or purpose remains unresolved, use `review`, not a forced yes/no verdict.
