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

No annotations are present, so the description must carry the behavioral disclosure burden. It only says 'Fetch' and 'sealed', implying a read-only, finalized receipt, but does not explain side effects, prerequisites, error behavior, or what 'sealed' means operationally.

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?

The description is a single compact sentence with no redundant words, and the key verb and resource are front-loaded. It is appropriately concise, though it is also quite terse.

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?

For a one-parameter fetch with an output schema, the description gives the minimal core needed to understand the operation. However, it lacks usage context such as when a sealed receipt becomes available and how to obtain job_id, and no annotations compensate for this gap.

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 description coverage is 0%, and the description adds only 'for a job,' which maps to job_id without explaining its format, provenance, or constraints. The schema's title 'Job Id' and string type carry nearly all the real parameter information.

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 uses the specific verb 'Fetch' with a precise resource ('sealed receipt summary') scoped to 'a job', making the core operation clear. It does not explicitly distinguish itself from siblings like hydracept_job_status or hydracept_job_inspect, but the receipt concept is distinct enough to avoid immediate confusion.

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 is given about when to call this versus alternatives such as hydracept_job_status, hydracept_job_inspect, or hydracept_jobs_find. It also does not explain what job state must be reached before a sealed receipt exists, leaving the selection decision entirely to the agent.

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