Execute MCP operations via **Gemini CLI** to preserve context budget. ## Execution Steps 1. **Execute task via Gemini CLI** (using stdin pipe for MCP support): ```bash # IMPORTANT: Use stdin piping, NOT -p flag (deprecated, skips MCP init) echo "$ARGUMENTS. Return JSON only per GEMINI.md instructions." | gemini -y -m gemini-2.5-flash ``` 2. **Fallback to mcp-manager subagent** (if Gemini CLI unavailable): - Use `mcp-manager` subagent to discover and execute tools - If the subagent got issues with the scripts of `mcp-management` skill, use `mcp-builder` skill to fix them - **DO NOT** create ANY new scripts - The subagent can only use MCP tools if any to achieve this task - If the subagent can't find any suitable tools, just report it back to the main agent to move on to the next step ## Important Notes - **MUST use stdin piping** - the deprecated `-p` flag skips MCP initialization - Use `-y` flag to auto-approve tool execution - **GEMINI.md auto-loaded**: Gemini CLI automatically loads `GEMINI.md` from project root, enforcing JSON-only response format - **Parseable output**: Responses are structured JSON: `{"server":"name","tool":"name","success":true,"result":<data>,"error":null}` ## Anti-Pattern (DO NOT USE) ```bash # BROKEN - deprecated -p flag skips MCP server connections! gemini -y -m gemini-2.5-flash -p "..." ```
