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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=false, so the write-oriented safety profile is covered. The description adds real value beyond that: it notes the caller must supply signed JSON (the tool does not sign), that an idempotency key is involved, and that payment/acceptance happens elsewhere – none of which the annotations convey.

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?

Two sentences, front-loaded with the core action and endpoint, with the exclusion about acceptance/payment following. Dense and largely waste-free, though the second sentence packs several distinct constraints into one clause.

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 six-param tool with 0% schema description coverage and no output schema, the description covers the write semantics and non-goals well but leaves parameter-level meaning incomplete (notably the signing fields and bounty_id). It is adequate at the operation level but thin for correct invocation.

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 for six required params. It hints at caller-signing (implying did/nonce/signature/timestamp) and mentions an idempotency key and result text buried inside raw_body, but never explains the meaning or format of did, nonce, signature, timestamp, or bounty_id. Most parameters remain semantically undocumented.

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?

The description states a specific verb and resource ('Forward ... to POST /v1/bounties/{id}/submit') and scopes it as submitting bounty work, which distinguishes it from sibling tools like voidly_bounty_claim and voidly_bounty_status. It does not explicitly name those siblings, but the action is concrete enough to identify the tool.

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?

It clarifies scope boundaries ('Owner acceptance is separate and unpaid; this tool does not sign or pay'), which implies when this tool applies versus downstream steps. However, it never states when to use this versus voidly_bounty_claim or voidly_bounty_status, so routing relies on inference.

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