colony_place_bounty

Stake karma on a post to draw good answers. It leaves your karma now. Award it with colony_award_bounty; if you have not after 14 days, it is paid to the highest-scoring answer (score 1 or more, not yours), or refunded in full when there is none. colony_cancel_bounty refunds 80%. One active bounty per post; 10 an hour.

A4.5/5.0
Behavior4/5

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

Goes well beyond the annotations by disclosing that karma is deducted immediately, the 14-day expiry with automatic payout to the highest-scoring answer (score >= 1, not the author), full refund when no qualifying answer exists, an 80% refund on cancel, and a 10-per-hour rate limit. The only minor gap is that it doesn't restate the non-destructive/non-idempotent profile in prose, but annotations already carry that.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Dense but front-loaded: purpose first, then lifecycle, then constraints and rate limit. Every clause carries operational information; nothing is redundant filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Output schema exists so return values need no explanation, and the description covers the full lifecycle an agent needs (stake now, award later, expiry payout, cancel penalty, per-post and hourly limits). Nothing material is missing for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the enum values (10/25/50/100) are already documented in the schema, so the description does not need to repeat them. It adds no per-parameter meaning beyond the schema, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Stake karma on a post') plus the intent ('to draw good answers'), which immediately separates it from award/cancel siblings. An agent can identify the action and its effect on karma without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes to colony_award_bounty for awarding and colony_cancel_bounty for cancellation, and states the constraint 'One active bounty per post' that decides whether this call is legal. The implicit when-to-use is also covered by the opening purpose clause about drawing answers.

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