# Now-Chess
|
|
|
|
Scala 3.5.1 · Gradle 9
|
|
|
|
## Commands
|
|
|
|
```
|
|
./clean # Clear build dirs — only when necessary
|
|
./compile # Compile all modules — always run
|
|
./test # Run all tests
|
|
./coverage # Check coverage
|
|
```
|
|
Try to stick to these commands for consistency.
|
|
|
|
## Modules
|
|
|
|
| Module | Role | Depends on |
|
|
|--------|------|-----------|
|
|
| `api` | Model / shared types | (none) |
|
|
| `core` | Primary business logic | api, rule |
|
|
| `rule` | Game rules | api |
|
|
| `io` | Export formats | api, core |
|
|
| `ui` | Entrypoint & UI | core, io |
|
|
|
|
## Style
|
|
|
|
- Use immutable data and pure functions.
|
|
- Keep functions under 30 lines. If you need "and" to describe it, split it.
|
|
- Keep cyclomatic complexity under 15.
|
|
- Avoid comments. Let names carry intent; comment only non-obvious algorithms.
|
|
- Scan for duplicated logic before finishing. Extract it.
|
|
- Follow default Sonar style for Scala.
|
|
- Use `Option` or `Either` for fallible operations; avoid exceptions for control flow.
|
|
- Naming: types are PascalCase, functions/values are camelCase.
|
|
|
|
## Code Quality
|
|
|
|
- **Coverage:** 100% condition coverage required in `api`, `core`, `rule`, `io` (mandatory); `ui` exempt.
|
|
|
|
## Architecture Decisions
|
|
|
|
- **Immutable state as primary model:** GameContext (api) holds board, history, player state — immutable, passed through the system. Each move creates a new GameContext, enabling undo/redo without side effects.
|
|
- **Observer pattern for UI decoupling:** GameEngine publishes move/state events; CommandInvoker queues moves; UI listens to events, not polling. GameEngine never imports UI code.
|
|
- **RuleSet trait encapsulates rules:** Move generation, check, castling, en passant all in RuleSet impl. GameEngine calls rules as a black box; rules don't know about the rest of core.
|
|
|
|
## Rules
|
|
|
|
- **Tests are the spec.** Never modify tests to pass; modify requirements or code. Update tests only if requirements change.
|
|
- Never read build folders. Ask permission if needed.
|
|
- Keep this file up to date with any important decisions or conventions.

## Instructions for Claude Code
|
|
|
|
### Two-Step Rule (mandatory)
|
|
**Step 1 — Orient:** Use wiki articles to find WHERE things live.
|
|
**Step 2 — Verify:** Read the actual source files listed in the wiki article BEFORE writing any code.
|
|
|
|
Wiki articles are structural summaries extracted by AST. They show routes, models, and file locations.
|
|
They do NOT show full function logic, middleware internals, or dynamic runtime behavior.
|
|
**Never write or modify code based solely on wiki content — always read source files first.**
|
|
|
|
Read in order at session start:
|
|
1. `.codesight/wiki/index.md` — orientation map (~200 tokens)
|
|
2. `.codesight/wiki/overview.md` — architecture overview (~500 tokens)
|
|
3. Domain article (e.g. `.codesight/wiki/auth.md`) → check "Source Files" section → read those files
|
|
4. `.codesight/CODESIGHT.md` — full context map for deep exploration
|
|
|
|
Routes marked `[inferred]` in wiki articles were detected via regex — verify against source before trusting.
|
|
If any source file shows ⚠ in the wiki, re-run `codesight --wiki` before proceeding.
|
|
|
|
Or use the codesight MCP server for on-demand queries:
|
|
- `codesight_get_wiki_article` — read a specific wiki article by name
|
|
- `codesight_get_wiki_index` — get the wiki index
|
|
- `codesight_get_summary` — quick project overview
|
|
- `codesight_get_routes --prefix /api/users` — filtered routes
|
|
- `codesight_get_blast_radius --file src/lib/db.ts` — impact analysis before changes
|
|
- `codesight_get_schema --model users` — specific model details
|
|
|
|
Only open specific files after consulting codesight context. This saves ~16.893 tokens per conversation.

## graphify
|
|
|
|
This project has a graphify knowledge graph at graphify-out/.
|
|
|
|
Rules:
|
|
- Before answering architecture or codebase questions, read graphify-out/GRAPH_REPORT.md for god nodes and community structure
|
|
- If graphify-out/wiki/index.md exists, navigate it instead of reading raw files
|
|
- After modifying code files in this session, run `python3 -c "from graphify.watch import _rebuild_code; from pathlib import Path; _rebuild_code(Path('.'))"` to keep the graph current
