This Skill addresses the issue where the Pi Orchestrator can easily fall into an infinite working loop. In practical development, when you assign a large task to Pi, the orchestrator might forget to delegate to sub-agents and instead continuously perform operations such as file reading, code searching, and content writing itself. After more than 20 rounds, it may still not have triggered any sub-agent delegation. This causes the task to get stuck at the orchestrator level, which is not only inefficient but also causes the system to lose its intended role as a coordinator.
Usage is straightforward: simply install the extension via npm and start a Pi session. It automatically detects the orchestrator role in the background, setting an upper limit of 3 preparation rounds + 3 effective working rounds. When the orchestrator fails to delegate to sub-agents for 3 consecutive rounds, the system injects a gentle reminder prompt into the context instead of forcibly blocking execution. The status bar displays real-time round counts and delegation status for clear visibility.
It is particularly suitable for developers who frequently use the Pi Orchestrator for complex task decomposition and coordination. This is especially useful in scenarios involving local models or models with weaker instruction-following capabilities, where the orchestrator is more prone to forgetting delegation rules. In such cases, this limiter effectively compensates for model behavioral deviations. Additionally, it can be paired with extensions that limit the parallel number of sub-agents to form a comprehensive agent collaboration management solution.
It is recommended to install this tool uniformly when developing AI applications requiring multi-step coordination to prevent context exhaustion due to prolonged orchestrator occupation. Note that it only affects the orchestrator and does not interfere with the normal operation of regular sub-agents. It does not forcibly interrupt tasks but rather encourages the orchestrator to revert to its delegation role via warnings. If a more restrictive approach is desired, it may need to be combined with other extensions.
Key Features
Unlike similar tools (e.g., a 7-round hard-blocking solution), the Pi Agent Turn Limiter employs a soft reminder mechanism. It only injects warnings without forcibly intercepting tool calls, preserving flexibility for the orchestrator's coordination. Furthermore, it targets only the orchestrator role, avoiding interference with normal sub-agent operations and preventing over-restriction.
Limitations
This extension is only compatible with the Pi Agent framework and requires the orchestrator's tool configuration to include the `subagent` tool for proper role detection. It may fail to trigger counting if a non-standard orchestrator is used.
FAQ
Does this extension forcibly prevent the orchestrator from continuing its work?
No, it only injects a reminder into the system prompt when the round limit is reached. It does not block any tool calls; the orchestrator can continue execution, but the context will prompt it to delegate to sub-agents.
Is manual configuration required after installation?
No, it takes effect automatically upon installation with all settings using default values (3 preparation rounds + 3 effective working rounds). You can view the real-time status at the bottom of the Pi TUI.
