Audit a project's Claude Code tool stack (MCP servers, plugins, hooks) against the curated recommendations at Context Radar (thoroc.github.io/context-radar): a 90-plus-tool, 20-layer comparison of context-reduction, memory, and code-nav tools for coding agents. Use when asked to review the Claude Code / MCP tool stack, check for redundant or conflicting tools, decide what to install next, or evaluate a new context/memory/code-nav tool against what's already running. DO NOT use for reviewing application dependencies (npm/cargo packages) or general code review - scope is Claude Code tooling only. Triggers: 'context radar', 'what tools should we use', 'audit our tool stack', 'is X redundant with Y', 'should I install this MCP server', 'tool stack review', 'context reduction tools'.
