Router and cheat-sheet for claude-mem MCP tools (prefix mcp__plugin_claude-mem_mcp-search__*). Use when users ask "did we solve this before?", "what did we do last session?", want to explore an unfamiliar codebase token-cheaply, or want to build a focused knowledge corpus from past work. Recognizes the 3-layer memory search pattern, AST-based smart_outline/unfold over Read, and the build→prime→query corpus lifecycle.
Use when context-mode MCP tools (ctx_batch_execute, ctx_execute, ctx_execute_file, ctx_search, ctx_fetch_and_index, ctx_index, ctx_stats, ctx_doctor) are available. Covers picking ctx over Bash/Read/WebFetch, batch-first gathering, think-in-code, intent for BM25 filtering, search throttling, hook-enforced anti-patterns. Triggers: "ctx", "context-mode", "keep output out of context", "index that", "token savings", "sandbox this".
