Add Example 6 showing how to create a hook that reports context/token usage after each Claude response: - Python script reads transcript_path to access conversation history - Estimates tokens using ~4 chars/token heuristic - Outputs one-line report: "Context: ~45k/200k tokens (77% remaining)" - Documents both Stop and UserPromptSubmit hook configurations - Explains limitations (estimate vs exact /context command)

Change: Add Context Usage Reporting Hook Example
Why
Users want to monitor their context window usage during Claude Code sessions. The hooks documentation currently lacks a practical example showing how to create a hook that reports context/token usage after each user request. This is valuable for understanding when context is getting full and when auto-compaction might occur.
What Changes
- Add a detailed example hook that reports context usage after each user prompt
- The hook will read the transcript file and estimate token usage
- Include step-by-step explanation of how the hook works
- Document the limitations (estimation vs exact token counts)
Impact
- Affected specs: hooks-documentation (add new example)
- Affected code:
06-hooks/README.md(add new example section) - User impact: Users gain a practical example for monitoring context usage
