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

The description adds real value beyond annotations by stating the signal is informational and does not affect bounty amount, funding, acceptance, ordering, or payout — consistent with destructiveHint=false and idempotentHint=true. It still omits auth/permission requirements beyond the implicit agent_key and says nothing about failure modes.

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 tight sentences: what it does, what it does not affect, and the key parameter constraint. No filler and the most important non-obvious facts lead.

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?

With no output schema, the description could say more about the response or the error when amount_usd is not above solver_payout_usd. For a lightweight informational write, however, it covers the essentials an agent needs to invoke it correctly.

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 67%, and the description compensates for the undocumented amount_usd by explaining it is the amount you would receive and must exceed the bounty's solver_payout_usd — a constraint absent from the schema's min/max bounds. This is exactly the kind of semantics a description should add.

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 or replace your price signal on an open or in-progress bounty') and clarifies the artifact is a signal, not the bounty itself. It does not explicitly distinguish itself from siblings like bounty_raise or bounty_pledge, so it stops short of a 5.

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 'open or in-progress bounty' phrasing implies the state in which this is valid, and 'post or replace' implies repeatability. But there is no explicit when-to-use vs. alternatives such as bounty_raise, bounty_pledge, or bounty_fund.

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