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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description adds the useful detail that ids are namespaced across sources, but says nothing about behavior for unknown/stale ids or what the 'full record' contains.

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?

A single sentence with the resource and the id-source stated up front, followed by compact inline examples. No waste.

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 single-param read tool with annotations and no output schema, the description covers enough to invoke it correctly. The only gap is any hint about what the returned record includes or how errors surface.

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 coverage is 0% and the single 'id' parameter has no description, so the description must carry this burden. Three concrete id-format examples (frantic:142, taskmarket:TSK-XXXX, algora:owner/repo#123) do that well, though it doesn't state whether the prefix is mandatory or case-sensitive.

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 and resource ('Full record for one bounty id') and explicitly ties it to list_bounties as the source of ids, which cleanly separates it from list_bounties and get_new_bounties.

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?

The phrase 'from list_bounties' implies the correct workflow: discover ids first, then fetch details here. It does not state exclusions (e.g. don't use this for bulk fetches), so it falls just short of a 5.

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