- AGENTS.md: universal cross-tool file read by Claude Code, Cursor, Codex, and OpenCode - .cursor/: 15 hook events via hooks.json, 16 hook scripts with DRY adapter pattern, 29 rules (9 common + 20 language-specific) with Cursor YAML frontmatter - .codex/: reference config.toml, Codex-specific AGENTS.md supplement, 10 skills ported to .agents/skills/ with openai.yaml metadata - .opencode/: 3 new tools (format-code, lint-check, git-summary), 3 new hooks (shell.env, experimental.session.compacting, permission.ask), expanded instructions, version bumped to 1.6.0 - README: fixed Cursor section, added Codex section, added cross-tool parity table - install.sh: now copies hooks.json + hooks/ for --target cursor

# Coding Style
|
|
|
|
## Immutability (CRITICAL)
|
|
|
|
ALWAYS create new objects, NEVER mutate existing ones:
|
|
|
|
```
|
|
// Pseudocode
|
|
WRONG: modify(original, field, value) → changes original in-place
|
|
CORRECT: update(original, field, value) → returns new copy with change
|
|
```
|
|
|
|
Rationale: Immutable data prevents hidden side effects, makes debugging easier, and enables safe concurrency.
|
|
|
|
## File Organization
|
|
|
|
MANY SMALL FILES > FEW LARGE FILES:
|
|
- High cohesion, low coupling
|
|
- 200-400 lines typical, 800 max
|
|
- Extract utilities from large modules
|
|
- Organize by feature/domain, not by type
|
|
|
|
## Error Handling
|
|
|
|
ALWAYS handle errors comprehensively:
|
|
- Handle errors explicitly at every level
|
|
- Provide user-friendly error messages in UI-facing code
|
|
- Log detailed error context on the server side
|
|
- Never silently swallow errors
|
|
|
|
## Input Validation
|
|
|
|
ALWAYS validate at system boundaries:
|
|
- Validate all user input before processing
|
|
- Use schema-based validation where available
|
|
- Fail fast with clear error messages
|
|
- Never trust external data (API responses, user input, file content)
|
|
|
|
## Code Quality Checklist
|
|
|
|
Before marking work complete:
|
|
- [ ] Code is readable and well-named
|
|
- [ ] Functions are small (<50 lines)
|
|
- [ ] Files are focused (<800 lines)
|
|
- [ ] No deep nesting (>4 levels)
|
|
- [ ] Proper error handling
|
|
- [ ] No hardcoded values (use constants or config)
|
|
- [ ] No mutation (immutable patterns used)
