Hor1zonZzz 86b5a53e5d refactor(rules): restructure into common + language-specific directories
* refactor(rules): restructure rules into common + language-specific directories

- Split 8 flat rule files into common/, typescript/, python/, golang/
- common/ contains language-agnostic principles (no code examples)
- typescript/ extracts TS/JS specifics (Zod, Playwright, Prettier hooks, etc.)
- python/ adds Python rules (PEP 8, pytest, black/ruff, bandit)
- golang/ adds Go rules (gofmt, table-driven tests, gosec, functional options)
- Replace deprecated ultrathink with extended thinking documentation
- Add README.md with installation guide and new-language template

* Fix installation commands for rules

Updated installation instructions to copy all rules to a single directory.

* docs: update README.md to reflect new rules directory structure

Performance Optimization

Model Selection Strategy

Haiku 4.5 (90% of Sonnet capability, 3x cost savings):

  • Lightweight agents with frequent invocation
  • Pair programming and code generation
  • Worker agents in multi-agent systems

Sonnet 4.5 (Best coding model):

  • Main development work
  • Orchestrating multi-agent workflows
  • Complex coding tasks

Opus 4.5 (Deepest reasoning):

  • Complex architectural decisions
  • Maximum reasoning requirements
  • Research and analysis tasks

Context Window Management

Avoid last 20% of context window for:

  • Large-scale refactoring
  • Feature implementation spanning multiple files
  • Debugging complex interactions

Lower context sensitivity tasks:

  • Single-file edits
  • Independent utility creation
  • Documentation updates
  • Simple bug fixes

Extended Thinking + Plan Mode

Extended thinking is enabled by default, reserving up to 31,999 tokens for internal reasoning.

Control extended thinking via:

  • Toggle: Option+T (macOS) / Alt+T (Windows/Linux)
  • Config: Set alwaysThinkingEnabled in ~/.claude/settings.json
  • Budget cap: export MAX_THINKING_TOKENS=10000
  • Verbose mode: Ctrl+O to see thinking output

For complex tasks requiring deep reasoning:

  1. Ensure extended thinking is enabled (on by default)
  2. Enable Plan Mode for structured approach
  3. Use multiple critique rounds for thorough analysis
  4. Use split role sub-agents for diverse perspectives

Build Troubleshooting

If build fails:

  1. Use build-error-resolver agent
  2. Analyze error messages
  3. Fix incrementally
  4. Verify after each fix
