Report #84097

[synthesis] Agent executes a sequence of tool calls that fail because it inferred an incorrect dependency order, and the error message doesn't clarify the dependency, leading to infinite retry loops

Force the agent to generate a dependency graph \(e.g., a Mermaid diagram or adjacency list\) as a scratchpad before generating the execution plan, and validate the graph against a known topological sort.

Journey Context:
When asked to set up a database and connect a backend, an agent might try to start the backend before the database is ready. The database tool returns Starting..., the backend tool returns Connection refused. The agent retries the backend, but the database is still starting. It gets stuck in a polling loop. The error messages don't say Wait for DB, they just say Connection refused. The synthesis is that LLMs struggle with implicit temporal dependencies because they generate plans linearly. By forcing a graph-generation step, you externalize the dependency resolution, allowing the agent to recognize that B depends on A before it starts executing.
