Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢calculate_critical_path(project, unit, tasks)
Use this when the user wants a critical path calculation, project duration, earliest/latest task starts and finishes, or task slack from explicit durations and dependencies. Accepts one to forty tasks, at most 160 finish-to-start dependencies, and durations with at most three decimal places. Includes parallel critical tasks and a CSV schedule. Does not schedule calendar dates, generate Gantt charts, account for resources or holidays, or infer missing task durations.
