## Pain
Domain owner: `studio/lsp`
PBS users do not get import-aware assistance, so discovering exported symbols and adding the right import from barrels, stdlib, or project modules remains manual.
## Context
Completion already exists for local/editorial contexts, and stdlib imports are understood by the compiler pipeline. The LSP does not yet provide auto-import completion, organize imports, or import quick fixes.
## Open Questions
- [ ] Should auto-import target project modules, stdlib modules, or both in the first wave?
- [ ] How should barrels and explicit module imports be ranked and rendered in completion?
- [ ] Should organize imports be a code action, source action, formatter responsibility, or separate feature?
## Options
### Option A - Import completion only
- **Approach:** Suggest symbols from known modules and include import detail, but do not edit imports automatically.
- **Pro:** Low risk and improves discovery.
- **Con:** Still leaves manual import edits.
- **Maintainability:** Good as a stepping stone.
### Option B - Auto-import and organize imports
- **Approach:** Completion/code actions insert missing imports and source actions sort/remove unused imports.
- **Pro:** Matches modern editor expectations.
- **Con:** Requires robust module export indexing and edit placement rules.
- **Maintainability:** Strong if built on a proper import graph.
## Tradeoffs
Auto-import depends on knowing canonical exports and choosing an edit location. Doing that ad hoc in completion would create formatting and duplicate import issues.
## Recommendation
Prefer Option B as the target, but start with import-aware suggestions plus a limited missing-import quick fix.
## Discussion
This should be coordinated with code actions and formatter.
## Resolution
Ainda em aberto.
## Next Step
Decide first-wave import sources: stdlib only, project modules only, or both.
