# Agent Instructions
These instructions apply to AI agents working in this repository, including OpenCode and Codex.
+ This file defines how to work safely in Nuri. It is not an implementation inventory, changelog, or session handoff. Use `docs/README.md` as the map to durable project documentation and inspect the current source before making claims about implementation status.
+
## Required Reading Before Work
- - English documents under `docs/` are the implementation source of truth for agents.
+ - Read `docs/README.md` to select the reference documents relevant to the change.
+ - English reference documents under `docs/` are the implementation source of truth.
- Before changing runtime, hooks, keys, lifecycle, reconciliation, invalidation, or performance code, read:
- 1. `docs/RUNTIME_ARCHITECTURE.md`
- 2. `docs/RUNTIME_IDENTITY.md`
- 3. `docs/LIFECYCLE.md`
- - When resuming work without reliable context, read `docs/SESSION_HANDOFF.md` first, then the relevant reference documents above.
+ 1. `docs/architecture/RUNTIME_ARCHITECTURE.md`
+ 2. `docs/architecture/RUNTIME_IDENTITY.md`
+ 3. `docs/architecture/LIFECYCLE.md`
+ - Read `docs/renderers/README.md` before changing renderer ownership, materialization, scheduling, or parity behavior.
+ - `docs/operations/SESSION_HANDOFF.md` is optional recovery context, not required reading or a source of truth. Verify it against current source and reference documents before relying on it.
- Korean translations for the project owner are under `docs/ko/`. Do not use a translation to override or reinterpret the English source of truth.
## Project Direction
- `Nuri` must stay platform-neutral.
- Do not add WPF, Avalonia, Duxel, Uno, OpenSilver, MAUI, or other UI framework types to `Nuri`.
- `Nuri.WPF` is the WPF renderer adapter and retains compatibility overloads where needed.
- `Nuri.Duxel` is the next UI backend development priority. Keep its immediate-mode materialization and Duxel package types outside Core.
- Component `Render()` methods should produce virtual UI descriptions, not native WPF controls.
- Native WPF controls should be created only by the WPF renderer/registry path.
- Preserve existing user-facing DSL compatibility unless the user explicitly approves a breaking change.
## Architecture Rules
- Keep platform-neutral concepts in `src/Nuri`:
- virtual entries
- patch operations
- diffing
- runtime/state
- element abstractions
- value models
- neutral event/animation descriptions
- Keep WPF materialization in `src/Nuri.WPF`:
- WPF control factories
- WPF property mapping
- WPF event delegate materialization
- WPF animation materialization
- Keep Duxel materialization in `src/Nuri.Duxel`:
- Duxel application/frame integration
- immediate-mode virtual-entry projection
- Duxel property, event, and animation materialization
- Future renderers should attach through Core contracts instead of depending on WPF code.
## Compatibility Rules
- Keep existing overloads such as WPF delegate event handlers unless removal is explicitly requested.
- Prefer adding neutral overloads beside existing WPF-specific overloads.
- `Name` currently remains a key fallback for compatibility.
- Prefer explicit `.Key("...")` for new keyed list examples.
## Performance Rules
- Preserve dirty component subtree render/diff/patch behavior.
- Preserve Dispatcher batching for state changes.
- Preserve keyed reconciliation and `MoveChildPatch` support.
- Use the `perf/` harness for before/after comparisons when optimizing.
- Treat patch count as an important metric, not just elapsed time.
## Validation
Run this after meaningful changes:
```powershell
dotnet build "Nuri.sln" -c Release
```
For performance sanity checks:
```powershell
dotnet run --project "perf\Nuri.Performance\Nuri.Performance.csproj" -c Release -- --label after
- dotnet run --project "perf\Nuri.WPFPerformance\Nuri.WPFPerformance.csproj" -c Release -- --label after
+ dotnet run --project "perf\Nuri.WPFPerformance\Nuri.WpfPerformance.csproj" -c Release -- --label after
```
## Documentation Policy
- Do not create broad documentation unless it prevents repeated rediscovery.
- - Use `docs/SESSION_HANDOFF.md` only to recover lost session context.
+ - Use `docs/README.md` to keep document roles, locations, and reading paths discoverable.
- Prefer focused samples over long explanatory docs.
- - When resuming without context, read `docs/SESSION_HANDOFF.md` first, then inspect only relevant source files.
+ - Before finishing each meaningful implementation session, review every related reference document for stale or missing statements; do not update only the first document that mentions the feature.
- Durable English reference documents must have a matching Korean translation under `docs/ko/`.
- - Update the English source and its Korean translation in the same change. Keep code symbols, paths, commands, API names, and measured numbers identical.
- - `docs/SESSION_HANDOFF.md` is an operational recovery file and does not require a full Korean mirror; summarize durable decisions in the paired reference documents instead.
+ - Keep the English and Korean documents in matching subdirectories and update both in the same change. Keep code symbols, paths, commands, API names, package versions, and measured numbers identical.
+ - `docs/operations/` contains optional operational notes and does not require a full Korean mirror. Move durable decisions into paired reference documents.
+ - Do not duplicate implementation inventories or long current-status lists in `AGENTS.md`; keep those facts in the appropriate reference document.
## Editing Rules
- Make small vertical slices that build.
- Do not rewrite large areas without a concrete reason.
- Do not revert user changes unless explicitly asked.
- Avoid introducing new external packages without confirming package direction first.
- Keep changes ASCII unless the edited file already uses non-ASCII or there is a clear reason.
- ## Current Feature Priorities
+ ## Change Workflow
- 1. Validate and refine existing Core-neutral event semantics across WPF and Duxel.
- - The baseline already includes click, text/content/check changes, hover, mouse down/up, keyboard down/up, focus changes, and loaded/unloaded compatibility events.
- - Prefer `useEffect(..., [])` and its cleanup for component mount/unmount behavior; do not expand loaded/unloaded as component lifecycle APIs.
- - Add richer pointer or keyboard payloads only when samples require modifiers, repeat state, handled semantics, coordinates, or device information.
- - Keep Avalonia as an existing regression baseline, not the next backend expansion target.
- 2. Complete platform-neutral animation support.
- - Keep `AnimationValue` renderer-neutral.
- - Expand supported properties and Duxel materialization based on sample needs.
- - Diagnose unsupported animation properties where actionable.
- 3. Strengthen renderer-level lifecycle/effect validation.
- - Verify effect flush after WPF native commit and Duxel frame projection, plus deterministic cleanup across subtree removal, key replacement, and repeated moves.
- 4. Improve WPF/Duxel semantic parity.
- - Close property, event, animation, lifecycle, and host-behavior gaps without forcing retained-control mechanics onto Duxel or moving framework types into Core.
- 5. Add diagnostics only where useful.
- - Render count and duplicate-key diagnostics already exist.
- - Prioritize patch count and unsupported property/event warnings when they help real samples.
- 6. Use the next samples to expose concrete gaps.
- - Prioritize Duxel-focused Explorer Tree, Animated Dashboard, Stress, and Multi-Window scenarios as host capabilities allow.
+ 1. Inspect the current worktree and the relevant source before assuming the handoff or reference documentation is current.
+ 2. Read the references selected through `docs/README.md` and identify the contracts the change must preserve.
+ 3. Make the smallest vertical change that keeps Core platform-neutral and renderer ownership explicit.
+ 4. Run focused tests, then the required Release solution build after meaningful changes.
+ 5. Review related English and Korean documentation for behavior, capability, command, package-version, and measurement drift.
