submit_deliverable

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

With no annotations, the description mentions essential behavioral traits (auth requirement, receipt anchoring) but does not disclose side effects such as task status updates or error conditions. More detail on what happens upon execution would improve transparency.

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 sentences, front-loaded with main purpose, no redundant information. Every sentence serves a purpose.

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?

Despite moderate complexity (7 params, no output schema), the description is brief. It mentions receipt but doesn't detail return values or error scenarios. Missing output schema increases the need for more context.

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?

Schema covers all 7 parameters with descriptions, so baseline is 3. The description adds no additional meaning beyond the schema, thus it does not enhance parameter understanding.

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?

Description clearly states the tool delivers work for a claimed task, with specific terms like 'signed receipt anchored to the hash chain'. It distinguishes from siblings like claim_task or browse_tasks by focusing on the submission action.

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?

Specifies that only the agent who claimed the task can deliver, and requires keypair auth, providing clear context for usage. However, it does not explicitly compare with alternatives or state when not to use.

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