Skills I keep coming back to.

Design test cases based on confirmed requirements and real failure mechanisms, clearly distinguishing between case design, red test handoff, validation, and authorized fix closed loops.

Coordinate development, testing, defect fixes, regression, and review based on confirmed requirements and implementable designs. Assess delivery status using complete user tasks and evidence.

Reproduce the failure, trace the first broken rule along the real execution path, and then validate the minimal fix within the authorized scope.

Perform a read-only review of PR, commits, branches, or workspace differences, trace callers, verify requirements, and provide evidence-based findings. The default is an in-depth Solo review.

A design language for AI programming agents: 24 design commands, real-time browser iteration, and 61 deterministic detection rules for identifying cookie-cutter, AI-generated front-end designs.

Investigate the current behavior and, before design begins, organize the goals into confirmed product requirements, clear decisions, and acceptance criteria.

Write or review actionable development, database, and interface designs. First verify key mechanisms, affected entry points, cross-layer contracts, and failure recovery, then determine whether the handoff is ready.

Agent Skills that provide artistic direction, reference images, and browser inspection for programming agents, aiming to create distinctive front-end designs rather than generic AI-styled pages.

A locally pre-indexed code knowledge graph for programming agents, automatically synchronized after code changes, aiming to reduce token usage and tool calls, covering agents such as Claude Code, Codex, Cursor, etc.

Engineering Agent Skills shared by Matt Pocock from his personal .agents directory: small, composable, easy to modify, and not bound to specific models.

An agent skill that makes programming agents prioritize minimal viable changes: fewer lines of code, less speculative code, simpler diffs. Think like the laziest seasoned developer in the room.
