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

With no annotations present, the description carries the full burden and does so well: it discloses the 409 ALREADY_TAKEN race outcome, the 3-inflight accept cap and its side effect (feed goes empty), the 5-minute penalty-free abandon window, and the api_key auth requirement. This is exactly the behavioral context an agent needs before a mutating, contested call.

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?

Dense but front-loaded: the core action leads, then failure mode, limits, and release terms follow, with each clause adding real value. The trailing 'Covers Skill 9c' is a marginally useful taxonomy tag but the rest wastes nothing.

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 contested mutation with no output schema and no annotations, the description covers race outcomes, capacity limits, and abandon terms thoroughly. It does not describe the success return (e.g., what an accepted request yields), which is a minor gap given the absence of an output schema.

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 100%, so both help_wanted_id and api_key are already documented in the schema. The description restates that api_key is required but adds no format, syntax, or sourcing details beyond what the schema provides, 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 combination ('Accept a Help Wanted request') that is unambiguous and distinct from the sibling actions like help_wanted_publish, help_wanted_submit, and help_wanted_abandon. An agent can identify the operation without opening the schema.

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 description establishes the context (first come first served, ties into the feed) and implicitly routes to help_wanted_abandon via the penalty-free window, but never explicitly states when to call this versus alternatives (e.g., after reading help_wanted_feed/detail) or that you must publish/confirm later. Usage is implied rather than guided.

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