What problem does it solve?

It solves the problem of turning scattered, conflicting Claude Code configuration into a secure, deterministic, layered “configuration as code” system that’s easy to audit and reproduce.

Core Features & Use Cases

• Settings hierarchy engineering: Design and validate the managed > CLI > local > shared > user precedence so the effective configuration is predictable.
• Permission rule design: Create allow/ask/deny Tool(specifier) rules to enforce least-privilege behavior (deny-first evaluation) and protect sensitive paths.
• CLAUDE.md + rules modularization: Optimize instruction loading using @imports and .claude/rules/ conditional frontmatter paths to control context size and behavior boundaries.
• Security boundary protection: Audit and calibrate AIOX L1–L4 boundary enforcement by ensuring deny/allow rules align with framework vs project mutability expectations.
• Context window optimization & enterprise deployment: Tune auto-compaction, environment strategy, and generate managed-settings.json for organization-wide policy.

Quick Start

Ask the agent to run the Claude Code configuration wizard for your project and generate the appropriate settings.json, CLAUDE.md, and .claude/rules/ structure.
