Perplexity

Enforce scope decomposition in Claude Desktop

Your AI client uses `validate_estimation` to break every task down into chunks of two days or less. This forces the model to confront hidden complexity before you commit to a date. Stop letting the agent hallucinate a timeline. By forcing granular decomposition, you expose the gaps in the plan that usually cause your sprints to slide.

Apply math-based buffers to your estimates

The `validate_estimation` tool requires a specific contingency buffer percentage for every task. You get a reality check based on whether the work is routine or novel. If the agent suggests a timeline without a 20% to 60% buffer, the tool rejects it. You force the AI to account for the unknowns that usually kill your project schedule.

Cite historical data in your planning

Don't accept gut feelings from your AI. The `validate_estimation` tool demands a specific historical precedent to justify the timeline you are building. This forces the agent to look at past performance rather than empty optimism. You stop the planning fallacy at the source by grounding every estimate in actual project history.
