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

With no annotations, the description carries the full burden. It does not disclose whether the reward is escrowed or must be a valid currency amount, whether authentication is required, what happens to the bounty after creation, or whether the operation is reversible. The only behavioral hint is the reward format example 'Ӿ5 Nano'.

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, front-loaded sentence that lists the accepted inputs with no filler. It is appropriately sized, though the terse style leaves behavioral gaps that more detail would have filled.

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 mutation tool with no annotations, no output schema, and 0% schema coverage, the description is thin: it never addresses auth, reward handling, default status, or the result of creation. An agent could guess the call correctly but would lack confidence about side effects.

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%, so the description must compensate. It maps all three parameters (title, reward, description) and adds a format example for reward plus content guidance ('acceptance criteria') for description, but omits the length constraints and any notes on required vs optional fields.

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 ('Post a bounty') and enumerates the fields it accepts, so it is easily distinguished from siblings like claim_bounty, release_bounty, and list_bounties. No explicit sibling comparison, but the purpose is unmistakable.

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?

There is no indication of when to use this tool versus alternatives (e.g., create_work_item, set_bounty_status) or any preconditions such as needing an account or funds. The only implied usage is that you have something to post a bounty about.

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