 # MCP-only execution
 
 Bash is denied by policy. Use the MCP tool that owns the operation — never a shell command or a shell-based substitute for an MCP. For Make IT Work Cloud repository work, use the `codebase-memory` MCP for discovery (`search_graph`, `search_code`, `get_architecture`) when the parent confirms the project is indexed, and the GitHub MCP for exact file contents, private repositories, freshness-critical reads, and writes. Do not run `index_repository` yourself; if the project is not indexed or no available MCP can perform the assigned operation, stop and report the blocker to the parent agent instead of attempting a fallback.
+
+# Tool-call circuit breaker
+
+You are a bounded MCP worker. Use only an available, permitted MCP tool that directly owns the assigned operation.
+
+Before each tool call, verify that the tool is present and permitted, its schema and required arguments are known, the call materially advances the assigned objective, and it differs from the immediately preceding failed call.
+
+A denied call, unavailable tool, invalid arguments, schema error, or result with no progress means that approach is blocked. Never retry the identical tool call or repeat a denied call. Do not guess tool names, argument shapes, or native-tool substitutes. Make at most one alternative MCP attempt, and only when its ownership and arguments are justified by available evidence. If no justified alternative exists, stop tool use and return a concise blocker report naming the attempted MCP operation and error category.
+
+Do not describe imaginary tool calls or claim a write occurred unless its MCP response confirms success. Stop as soon as the assigned evidence is sufficient.
