AGENT NOTES

Styling Guidelines

• Reuse the existing token & utility layers before introducing new CSS variables or custom properties. Extend src/styles/tokens.css / src/styles/utilities.css if a shared pattern is needed.
• Keep aggregate entry files (e.g., src/styles/controls.css, messaging.css, panels.css) lean—they should only @import feature-specific subfiles located inside src/styles/{components|messaging|panels}.
• When adding new component styles, place them beside their peers in the scoped subdirectory (e.g., src/styles/messaging/new-part.css) and import them from the corresponding aggregator file.
• Prefer smaller, focused style files (≈150 lines or less) over large monoliths. Split by component or feature area if a file grows beyond that size.
• Co-locate reusable UI patterns (buttons, selectors, dropdowns, etc.) under src/styles/components/ and avoid redefining the same utility classes elsewhere.
• Document any new styling conventions or directory additions in this file so future changes remain consistent.

Coding Principles

• Favor KISS by keeping modules narrowly scoped and limiting public APIs to what callers actually need.
• Uphold DRY: share helpers via dedicated modules before copy/pasting logic across stores, components, or scripts.
• Enforce single responsibility; split large files when concerns diverge (state, actions, API, events, etc.).
• Prefer composable primitives (signals, hooks, utilities) over deep inheritance or implicit global state.
• When adding platform integrations (SSE, IPC, SDK), isolate them in thin adapters that surface typed events/actions.

File Length Guidelines (Highlight Only)

We track file size as a refactoring signal. When you touch or create files, highlight oversized files so the team can plan refactors when time permits.

• Source files: warn after ~500 lines; target limit ~800 lines
• Test files: highlight after ~1000 lines

Behavior for agents:

• Do not refactor solely to satisfy these thresholds.
• When a change touches a file that exceeds the warning/limit, mention it in your final response and include the file path and approximate line count.
• When creating new files, aim to stay under the thresholds unless there's a clear reason.

Tooling Preferences

• Use the edit tool for modifying existing files; prefer it over other editing methods.
• Use the write tool only when creating new files from scratch.
