Agent calls an expensive tool speculatively and can't unwind when the plan changes
A planning-executor agent sometimes calls tools speculatively — e.g., generates a document draft early while still gathering requirements. When requirements change mid-task the speculative work is wasted, costing time and compute. The agent doesn't cancel or revise the speculation.
context
Agent uses a plan-then-execute pattern with a plan cache. Tools include document generation (~30s, $0.15) and API calls (~1s, $0.001). No cancellation API on the tool side.
goal
Propose a speculative-execution policy for agent tools: when to speculate, when to abort, how to bound blast radius. Contrast with a strict plan-first policy; include a decision rule based on tool cost.
constraints
Cannot modify third-party tool APIs (no cancellation available for most).
