demo5_retry_task

Retry a failed or cancelled task by resuming from the last step or restarting with modified parameters. Optionally fix the failing step to ensure success.

Instructions

Retry a failed or cancelled task. Can resume from where it stopped or restart entirely with modified parameters.

Behavior3/5

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

No annotations are provided, so the description carries full burden. It explains resume vs restart and hints at modifying parameters, but does not disclose whether retrying creates a new task, what happens to the original task, or prerequisites like task state requirements.

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

Conciseness5/5

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

Two concise sentences with no unnecessary words. The main action is front-loaded, and each sentence adds value.

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

Completeness3/5

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

The description covers the basic purpose but lacks details on return values, side effects, and how 'modified parameters' relate to the schema. Given moderate complexity and no output schema, more completeness would be beneficial.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents all parameters. The description adds context about resume/restart and modified parameters but does not add syntax or format details beyond the schema.

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

Purpose5/5

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

The description clearly states the verb 'retry' and the resource 'task', and specifies it's for failed or cancelled tasks. It distinguishes from sibling tools like demo5_cancel_task and demo5_list_tasks.

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

Usage Guidelines4/5

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

The description implies usage when a task is failed or cancelled, and mentions two modes (resume/restart) to guide selection. However, it does not explicitly exclude other scenarios or compare to alternatives.

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