No way for MCP clients to request different preview sizes\n2. No way to disable compaction for debugging\n3. No way to adapt to different context window sizes\n4. Values are not documented in tool schema\n\n## Recommended Solution\nAdd environment variables or MCP tool parameters:\n- `BEADS_MCP_COMPACTION_THRESHOLD` env var (default: 20)\n- `BEADS_MCP_PREVIEW_COUNT` env var (default: 5)\n- Optional `compact_threshold` and `preview_size` parameters to list/ready tools\n\n## Implementation Notes\n- Keep current defaults for backward compatibility\n- Read from environment at server initialization\n- Document in CONTEXT_ENGINEERING.md\n- Add tests verifying env var behavior","status":"closed","priority":3,"issue_type":"task","created_at":"2025-12-14T14:24:34.037997-08:00","updated_at":"2025-12-14T14:40:48.79752-08:00","closed_at":"2025-12-14T14:40:48.79752-08:00","dependencies":[{"issue_id":"bd-4u2b","depends_on_id":"bd-otf4","type":"discovered-from","created_at":"2025-12-14T14:24:34.039165-08:00","created_by":"stevey"}]}
