resume_state

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must fully disclose behavior. It lists what is restored but omits critical details: whether it overwrites current state, what happens if no checkpoint exists, potential side effects, or authentication/permission requirements. This is insufficient for a state restoration tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two clear, front-loaded sentences with zero wasted words. The first sentence states the main action, and the second specifies exactly what is restored. Excellent conciseness and structure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the presence of an output schema (though not shown), the description is partially complete. However, for a tool that restores state, it lacks essential context about error handling, prerequisites, and behavior without an existing checkpoint. The description is adequate but not fully self-contained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist, so the baseline is 4. The description adds meaning by explaining the restoration action and listing affected components, which goes beyond the trivial schema (empty object). It clearly conveys what the tool accomplishes.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the verb 'Resume' and the resource 'state from the latest checkpoint', listing specific components restored (context fragments, dedup index, co-access patterns, custom metadata). This clearly distinguishes it from siblings like checkpoint_state, which saves state.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives, such as its counterpart checkpoint_state. It does not mention prerequisites (e.g., a checkpoint must exist) or situations where it should not be used, leaving the agent without crucial decision-making information.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
