Toise

Deep clean and structural health check for Claude-maintained software.

Purpose: When you're uncertain whether the ground is solid — early foundations, mid-project drift, scale pressure — toise gives you an honest, evidence-backed answer. It finds the dustballs behind the sofa, flags drift that accumulated across sessions, and occasionally surfaces structural concerns that session-level review can't see.

Core thesis: Claude is the primary code-touching entity in these codebases. Architecture that works for Claude encodes global decisions in discoverable artefacts so that each fresh session can do good local work without the architect in the room. Five principles capture what makes this work (see references/principles.md).

Relationship to other tools:

• Toise = periodic deep clean + structural assessment (this skill)
• Titans = session-level code review (bugs, craft, idiom)
• understanding.md = the soul. Toise reads it for context, never writes to it.
• CLAUDE.md = the manual. Toise proposes improvements to it.
