You MUST use this when an approved design or settled requirements need a detailed multi-step implementation plan before code changes begin.
Evidence-grounded to-be design (ADRs + design doc) and an implementation orchestration plan (a machine-readable task ledger). Activates when the user asks to design a target state, plan the work, or produce a task plan for a goal.
Expert in requirements definition and system design. Converts abstract requirements into concrete specification documents (SPEC.md) and design documents (DESIGN.md), and visualizes system structures using Mermaid diagrams.
Converts architecture descriptions, module specs, or workflow docs into Mermaid diagrams. Use when visualizing brick module relationships, workflows (DDD, investigation), or system architecture. Supports: flowcharts, sequence diagrams, class diagrams, state machines, entity relationship diagrams, and Gantt charts. Generates valid Mermaid syntax for embedding in markdown docs.
Analyze code for performance and efficiency improvements
Convert PRD to structured task list with automatic linking
Use when a repository needs cleanup of dead code, build artifacts, unused dependencies, outdated docs, or stale tests - provides safe cleanup workflows, validation steps, and reporting templates for code, deps, docs, tests, and sprint archives.
Design and document statistical algorithms with pseudocode and complexity analysis
Creates Source-of-Truth docs (Project Brief, Decisions, Glossary) for new app ideas. Use at the very start of a project to lock scope, stack, and terminology. Essential for preventing drift in downstream PRD, UI/UX, and Architecture phases.
Create Atomic Requirements (REQ) - Layer 7 artifact using REQ v3.0 format with 12 sections, SPEC-readiness scoring, and IMPL-readiness scoring
Governance-focused README with fixed structure and output contract. Use for asset governance, audit, or standardized first-impression docs. For process-driven creation (templates by project type) use crafting-effective-readmes.
Always Auto-invoked skill that creates/updates workspace AGENTS.md to instruct the agent to always search for existing skills before attempting any scientific task.
