Condition-Based Waiting

Replace fixed delays with condition polling for more reliable async tests.

Defense-in-Depth Validation

Design layered validation across data flows to prevent bugs and security issues.

Testing Skills With Subagents

Iteratively test process documentation to find gaps and refine instructions.

Domain-Focused Naming

Name code by domain meaning to improve clarity and team alignment.

Writing Evergreen Comments

Write evergreen comments focused on what and why, not historical context.

Root Cause Tracing

Trace bugs backward through call stacks to find the original trigger.

Commenting Intent

Helps developers write code comments explaining intent, rationale, and key tradeoffs.

Dispatching Parallel Agents

Dispatch multiple agents in parallel to investigate and fix independent issues.

Finishing a Development Branch

Helps developers finish a branch with merge, PR, or cleanup workflows.

Subagent-Driven Development

Execute implementation plans with task-specific subagents and code review checkpoints.

Requesting Code Review

Trigger a code review against plans or requirements before moving forward.

Using Git Worktrees

Gardening Skills Wiki

Check a skills wiki for links, naming, cross-references, and coverage gaps.

Testing Anti-Patterns

Helps developers avoid common testing anti-patterns and write more reliable tests.

Single Purpose Variables

Improve code clarity and maintainability by assigning each variable one purpose.

Executing Plans

Execute detailed plans in batches with review checkpoints and course correction.

Simplifying Control Flow
