Help with MongoDB query optimization and indexing. Use only when the user asks for optimization or performance: "How do I optimize this query?", "How do I index this?", "Why is this query slow?", "Can you fix my slow queries?", "What are the slow queries on my cluster?", etc. Do not invoke for general MongoDB query writing unless user asks for performance or index help. Prefer indexing as optimization strategy. Use MongoDB MCP when available.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MongoDB Query Optimizer ## When this skill is invoked Invoke **only** when the user wants: - Query/index **optimization** or **performance** help - **Why** a query is slow or **how to speed it up** - **Slow queries** on their cluster and/or **how to optimize them** Do **not** invoke for routine query authoring unless the user has requested help with optimization, slow queries, or indexing. ## High Level Workflow ### General Performance Help If the user wants to examine slow queries, or is looking for general performance suggestions (not regarding any particular query): - Use MongoDB MCP server **atlas-get-performance-advisor** tool to fetch slow query logs and performance advisor output - Make suggestions based on this information If Atlas MCP Server for Atlas is not configured or you don’t have enough information to run **atlas-get-performance-advisor** against the correct cluster, tell the user that general performance analysis requires Atlas MCP Server configuration with API credentials, and suggest they configure it or ask about a specific query instead. ### Help with a Specific Query If the user is asking about a particular query: …

How to install
mdr add fcakyon/claude-codex-settings/mongodb-query-optimizer@sha256:62a5bff5f4050596The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
