1. Software Development

Verifies parent-child inheritance relationship in skill system without MCP tool usage.

Systematically implements technical plans with verification, phase tracking, and file-specific testing for complex feature development.

Enables parallel execution of child skills for testing, enhancing test efficiency and coverage in skill-based development.

Requests peer code reviews for major features and task completion to verify adherence to requirements and quality standards before merging.

A test utility that invokes an error-prone child component to verify error propagation mechanisms in a system.

Tests return value propagation from Layer 3 (innermost) to Layer 2 in nested function structures.

Verifies TaskCreate, List, Get, and Update tool availability in forked skills to ensure functional consistency.

Verifies that the 'allowed-tools' configuration correctly restricts available tools in the system.

Tests MCP tool availability in allowed-tools list without requiring MCPSearch functionality.

Tests if tasks created in parent conversation are visible to forked skills.

Tests the substitution of $ARGUMENTS variables in skill content to verify correct rendering.

Requires verification command execution and output confirmation before claiming code completion, commit, or PR creation to prevent false positives.

Writes timestamps in child processes for parallel test coordination, enabling precise timing analysis in test suites.

Validates dynamic configuration of CLAUDE_CODE_TASK_LIST_ID for code task management systems.

Tests whether disallowedTools configuration effectively blocks MCP tools in the model's tool management system.

Enables parallel execution of independent tasks without shared state or sequential dependencies through agent-based dispatching.

Verifies return path behavior in nested function calls, ensuring child functions correctly return to immediate parent or skip to grandparent level.

Executes an isolation test by writing a secret and verifying sibling A's secret in a secret management system.

Validates the Task tool's parallel subagents implementation in SDK environments.

Deliberately fails to test error propagation in skill chains during development testing.

Orchestrates Layer 2 in a 3-layer test framework for automated testing and validation.

Systematically diagnoses software bugs, test failures, and unexpected behavior to determine root causes before proposing fixes.

Verifies presence and functionality of TaskCreate, List, Get, and Update tools in SDK-calling forked skills.

Generates detailed implementation plans for complex features, refactors, and multi-phase projects with research, iteration, and success criteria.
