  • Status Tracking: Clear confirmation that the GPT-5 compatibility crisis is fully resolved
  • Cross-Reference Integration: Links to companion implementation PRs for full context

✅ Resolution Confirmation

  • GPT-5 Parameter Issues: Fully resolved via transformer improvements
  • Tools Format Errors: Fixed via JSON schema metadata cleanup
  • Reasoning Token System: Working inline control tokens deployed
  • Cross-Repository Integration: Tested and documented end-to-end

🎯 User Experience Impact

  • Status Clarity: Users now see clear "resolved" status instead of "pending"
  • Modern Context: Documentation reflects current 2025 model ecosystem
  • Success Story: Documents successful resolution of major compatibility crisis
  • Future Reference: Preserved knowledge for similar integration challenges

📚 Educational Value

  • Problem Resolution Documentation: Shows how major API compatibility issues are resolved
  • Cross-Repository Coordination: Example of systematic approach to multi-repo features
  • Status Management: Best practices for tracking and communicating bug resolution
  • Timeline Maintenance: Importance of keeping documentation current with rapid AI evolution

🔗 Complete Solution Chain

This PR completes the 4-PR solution set:

  1. LLMS PR #1: Core GPT-5 API compatibility fixes
  2. CCR PR #1: Inline reasoning control token implementation
  3. LLMS PR #2: Technical documentation and API guide
  4. [CCR PR Could you provide the file .env.example? #2]THIS PR: User documentation and resolution confirmation

🏁 Crisis Resolution Complete

With this PR, the GPT-5 reasoning parameter compatibility crisis that blocked Claude Code interactive mode is:

  • Technically Resolved: Core fixes implemented and tested
  • User Experience Enhanced: Inline tokens provide intuitive control

Prevent local Claude Code settings from being committed to repository.
These files contain personal development tool preferences that should
remain local to each developer.
- Update package.json to use llms v1.0.26 with GPT-5 support
- Add comprehensive debug logging in index.ts for troubleshooting
- Implement GPT-5 parameter mapping in router.ts (max_tokens → max_completion_tokens)
- Working GPT-5 through CCR with tool format conversion

Add comprehensive inline token system for controlling GPT-5 reasoning effort
and verbosity without requiring separate CLI flags or configuration.

Features:
- Prefix tokens: Quick:, Deep:, Explain:, Brief: (beginning of prompt)
- Colon tokens: :quick, :deep, :explain, :brief (anywhere in prompt)
- Automatic token detection, parameter mapping, and prompt stripping
- Integration with CCR router middleware for seamless processing
- Avoids conflicts with Claude Code's # memory system

Token mappings:
- Quick/:quick → low effort, low verbosity (500 token budget)
- Deep/:deep → high effort, medium verbosity (2000 token budget)
- Explain/:explain → medium effort, high verbosity (1000 token budget)
- Brief/:brief → medium effort, low verbosity (1000 token budget)

Implementation in src/utils/router.ts:153-210 processes tokens before
API calls, automatically strips them from prompts, and sets appropriate
reasoning_effort, verbosity, and thinking parameters for downstream
transformers.

Documentation includes comprehensive reference table and usage examples
in CLAUDE.md inline token section.

Replace outdated GPT-4 references with current 2025 model comparisons:
- GPT-5 vs o3/o4-mini performance differences
- Token usage: GPT-5 2000+ vs o3/o4-mini 500 reasoning tokens
- Architecture evolution: unified vs specialized reasoning models
- Performance improvements: 50-80% fewer tokens, 6x fewer hallucinations
- Tool capabilities: GPT-5 agentic integration vs o3 limitations

Reflects actual 2025 release timeline with GPT-5 (Aug 2025),
o3/o4-mini as current generation models rather than legacy comparisons.
