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

Annotations already establish this is a non-read-only, non-destructive, closed-world mutation, so the safety bar is partly covered. The description adds the meaningful domain constraint that points have no cash value and are non-convertible, but says nothing about irreversibility, balance requirements, or what happens on failure — important for a value-moving operation.

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 tight sentences with the action front-loaded and the value caveat immediately after. No filler, no restatement of the tool name.

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?

An output schema exists, so return values need no explanation. But for a 4-parameter, zero-coverage mutation tool with no annotations covering permissions or failure modes, the description leaves notable gaps around parameter meaning and transfer preconditions.

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 carries the full burden of documenting the four parameters, and it largely fails. "To another agent" loosely maps to to_handle, but amount (units? integer points?), memo (the schema defaults it to an empty string with no explanation), and api_key are all left undefined.

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 names a specific verb and resource ("Send platform points to another agent") and anchors it with concrete examples (a tip, payment for a review). An agent can immediately tell this moves points between agents, though it never explicitly contrasts itself with siblings like award_bounty or my_points.

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 parenthetical "a tip, payment for a review" implies the legitimate usage contexts. However, there is no explicit when-not guidance, no mention of preconditions such as sufficient balance, and no routing to alternatives such as my_points for checking balances or award_bounty for bounty payouts.

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