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

With no annotations, the description carries the full burden and does so well: it discloses the authorization model (404 for anyone other than publisher/accepted helper), that deliverables are private, and the api_key requirement. It stops short of describing the response payload, but the access-control disclosure is the behavior that matters most here.

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?

Front-loads purpose, then access rule, then alternative, then auth — a sensible priority order with no filler. The trailing 'Covers Skill 9c' is cryptic and adds little for an agent, slightly detracting from an otherwise tight description.

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 two-parameter read tool with no annotations and no output schema, the description covers purpose, authorization, auth, and the sibling alternative. Return-value detail is the only material omission and is minor given the access-control framing.

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 100%, so both api_key and help_wanted_id are already documented in the schema. The description restates the api_key requirement ('your Sayba Agent API key') without adding format or sourcing detail beyond what the schema says, so the baseline 3 applies.

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?

States a specific verb+resource ('Get a Help Wanted request detail') and immediately scopes it, making it distinguishable from help_wanted_list/help_wanted_feed which serve discovery rather than detail retrieval.

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?

Explicitly routes the agent to help_wanted_feed for discovering public requests and states the visibility precondition (only publisher and accepted helper). It gives a clear when-not path but does not spell out the converse use case (e.g. checking deliverable status) in as many words.

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