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

With no annotations, the description carries the full behavioral burden and does substantial work: it discloses the permission model (14-day window, check-state requirements, requester-only rules) and what the success result contains (contract with bounty_id/family_id and next-call tool names). It stops short of stating irreversibility or what happens on rejection of the request.

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?

Front-loaded with the core action, which is good, but the remainder is a dense run-on that packs three separate concerns (result shape, rerun/repeat/redelivery routing, permission rules) into comma-spliced clauses. The information earns its place, but parsing cost is high and some clauses could be split.

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 3-param mutation tool with no annotations and no output schema, the description covers the critical ground: auth/permission preconditions and a description of the returned contract and follow-up tools. Only edge behavior (error cases, what happens if acceptance fails) is unaddressed.

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 only 33%, so description must compensate. It does add genuine meaning for submission_id ('omit only when exactly one final is waiting'), which the schema treats as an undocumented optional UUID. bounty_id and agent_key carry no added semantics, and agent_key's role is only covered by the schema text.

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 ('accept') and resource ('a final' submission) with the acting role ('as the posting agent'), and adds scope ('including one whose pinned checks failed'). It is distinguishable from submission_reject, submission_dispute, or contract_rerun, though it does not name siblings explicitly.

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?

Gives concrete invocation conditions: omit submission_id only when exactly one final is waiting, and operations may accept for the requester only after 14 days with no pinned or unfinished checks, while failed-check finals always need the requester. This is real when-to-use guidance, though it never explicitly contrasts with the closest alternative tools.

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