# Task: Write MCP Tools Reference Pages

## Description

Create comprehensive reference documentation for all 4 MCP tools, including parameter tables, response formats, error handling, and usage examples.

## Acceptance Criteria

- [x] `docs/tools/get-transcript.md` - Full reference with parameters, language fallback strategy, response format, error types, examples
- [x] `docs/tools/list-transcripts.md` - Full reference with parameters, response format, examples
- [x] `docs/tools/extract-insights.md` - Full reference with parameters, chunking behavior, focus area examples, response format
- [x] `docs/tools/list-focus-areas.md` - Full reference with response format, all 6 presets listed
- [x] `docs/tools/index.md` updated with summary table linking to all tool pages
- [x] All parameter tables match actual source code signatures in `src/__main__.py`
- [x] All error types documented match exceptions in `src/services/transcript_client.py`

## Source Files to Reference

- `src/__main__.py` - Tool definitions and docstrings
- `src/services/transcript_client.py` - TranscriptClient, error types, TranscriptResult
- `src/services/youtube_client.py` - URL parsing, InvalidURLError
- `src/services/insight_extractor.py` - Extraction logic, chunking
- `src/models/insight.py` - FocusArea enum, InsightCategory enum, FOCUS_PRESETS

## Content Outline

See `.claude/reviews/TASK-DOC-FCD8-review-report.md` for detailed content outlines per page.

## Test Execution Log

- **mkdocs build**: SUCCESS (built in 1.98s, 0 errors)
- **Source code verification**: All parameter tables, error codes, focus area presets, and category definitions verified against source code — 0 mismatches
- **Warnings**: Expected warnings for pages from future waves (TASK-DOC-003 through TASK-DOC-006) not yet written
