Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Specification-Driven Development (SDD) workflow for creating, modifying, and validating specs. Use when (1) creating new specs, (2) modifying existing specs, (3) checking spec consistency (parent/child, depends_on/used_by relationships), (4) answering questions about spec structure or format, (5) setting up a specs/ directory. Specs are the single source of truth - when code and spec diverge, the spec is correct.

Creates comprehensive handoff documents for seamless AI agent session transfers. Triggered when: (1) user requests handoff/memory/context save, (2) context window approaches capacity, (3) major task milestone completed, (4) work session ending, (5) user says 'save state', 'create handoff', 'I need to pause', 'context is getting full', (6) resuming work with 'load handoff', 'resume from', 'continue where we left off'. Proactively suggests handoffs after substantial work (multiple file edits, complex debugging, architecture decisions). Solves long-running agent context exhaustion by enabling fresh agents to continue with zero ambiguity.
