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

With no annotations, the description carries the full burden but discloses genuinely non-obvious behavior: posting is unfunded and free, the task is not executable until a payer (or run_task) funds it, and it returns a task id. It omits whether the public posting is permanent/irreversible and any reputation or auth implications of the requester field.

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?

Three short, front-loaded sentences with no waste: purpose first, lifecycle constraint second, return value last. Every sentence carries distinct information.

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 4-parameter mutation tool with an undocumented nested args object and no output schema, the description is reasonably complete: it covers what the tool does, the funding lifecycle, and the return value. It leaves the board's visibility/permanence and the nested args format to the 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 description coverage is 100%, so the schema already documents type, args, requester, and bounty_cents, establishing a baseline of 3. The description adds only marginal meaning, clarifying that the bounty is what makes the posted task executable and that posting itself is free, which gently disambiguates the bounty_cents parameter.

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?

Specific verb+resource: 'Post a task to the public board with a bounty,' which clearly distinguishes posting from the sibling read/execute tools (get_task, list_tasks, run_task). It stops short of naming which sibling to use instead, but the action is unambiguous.

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 implies usage by explaining the bounty lifecycle ('it becomes executable once someone (or run_task) pays'), which tells the agent how this tool fits with run_task. However, there is no explicit 'use this when... not that' guidance or preconditions (e.g., when to post versus run directly).

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