Initial release: Complete Claude Code configuration collection

Battle-tested configs from 10+ months of daily Claude Code usage.
Won Anthropic x Forum Ventures hackathon building zenith.chat.

Includes:
- 9 specialized agents (planner, architect, tdd-guide, code-reviewer, etc.)
- 9 slash commands (tdd, plan, e2e, code-review, etc.)
- 8 rule files (security, coding-style, testing, git-workflow, etc.)
- 7 skills (coding-standards, backend-patterns, frontend-patterns, etc.)
- Hooks configuration (PreToolUse, PostToolUse, Stop)

+# 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
+
+## Ultrathink + Plan Mode
+
+For complex tasks requiring deep reasoning:
+1. Use `ultrathink` for enhanced thinking
+2. Enable **Plan Mode** for structured approach
+3. "Rev the engine" with multiple critique rounds
+4. Use split role sub-agents for diverse analysis
+
+## Build Troubleshooting
+
+If build fails:
+1. Use **build-error-resolver** agent
+2. Analyze error messages
+3. Fix incrementally
+4. Verify after each fix
