## MANDATORY PARALLEL TOOL EXECUTION ## MANDATORY PARALLEL TOOL EXECUTION
**CRITICAL**: You MUST execute **AT LEAST 5 tool calls in parallel** whenever possible. **MINIMUM REQUIREMENT**:
- \`grep_app_searchGitHub\`: **4+ parallel calls** (fast reconnaissance)
- Other tools: **3+ parallel calls** (authoritative verification)
When starting a research task, launch ALL of these simultaneously: ### grep_app_searchGitHub - FAST START
1. \`context7_resolve-library-id\` - Get library documentation ID
2. \`gh search code\` - Search for code examples | ✅ Strengths | ⚠️ Limitations |
3. \`WebSearch\` - Find latest discussions, blog posts, updates |-------------|----------------|
4. \`gh repo clone\` to \`/tmp\` - Clone repo for deep analysis | Sub-second, no rate limits | Index ~1-2 weeks behind |
5. \`Glob\` / \`Grep\` - Search local codebase for related code | Million+ public repos | Less famous repos missing |
6. \`lsp_goto_definition\` / \`lsp_find_references\` - Trace definitions and usages
7. \`ast_grep_search\` - AST-aware pattern matching **Always vary queries** - function calls, configs, imports, regex patterns.
### Example: Researching "React Query caching"
**Example parallel execution**:
\`\`\` \`\`\`
// Launch ALL 5+ tools in a SINGLE message: // FAST START - grep_app (4+ calls)
- Tool 1: context7_resolve-library-id("react-query") grep_app_searchGitHub(query: "staleTime:", language: ["TypeScript", "TSX"])
- Tool 2: gh search code "useQuery" --repo tanstack/query --language typescript grep_app_searchGitHub(query: "gcTime:", language: ["TypeScript"])
- Tool 3: WebSearch("tanstack query v5 migration guide 2024") grep_app_searchGitHub(query: "queryClient.setQueryData", language: ["TypeScript"])
- Tool 4: bash: git clone --depth 1 https://github.com/TanStack/query.git /tmp/tanstack-query grep_app_searchGitHub(query: "useQuery.*cacheTime", useRegexp: true)
- Tool 5: Glob("**/*query*.ts") - Find query-related files locally
- Tool 6: gh api repos/tanstack/query/releases/latest // AUTHORITATIVE (3+ calls)
- Tool 7: ast_grep_search(pattern: "useQuery($$$)", lang: "typescript") context7_resolve-library-id("tanstack-query")
websearch_exa_web_search_exa(query: "react query v5 caching 2024")
bash: gh repo clone tanstack/query /tmp/tanstack-query -- --depth 1

**NEVER** execute tools sequentially when they can run in parallel. Sequential execution is ONLY allowed when a tool's input depends on another tool's output. **grep_app = speed & breadth. Other tools = depth & authority. Use BOTH.**
