import type { BottleneckTask } from '@cleocode/contracts';
/**
 * Show blocked tasks and analyze blocking chains.
 *
 * @param projectRoot - Absolute path to the CLEO project root directory
 * @param params - Optional analysis configuration
 * @param params.analyze - When true, compute transitive blocking chains
 * @param params.limit - Maximum number of blocked tasks to return (default: 20)
 * @returns Blocked tasks with optional blocking chains, critical bottleneck tasks, and a summary
 *
 * @remarks
 * Collects both explicitly blocked tasks and dependency-blocked pending tasks.
 * Critical blockers are the top 5 tasks that appear most frequently in blocking chains.
 *
 * @example
 * ```typescript
 * const result = await coreTaskBlockers('/project', { analyze: true, limit: 10 });
 * console.log(result.summary, result.criticalBlockers);
 * ```
