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

Annotations supply only readOnlyHint=false, so the description must carry the behavioral load. It does add real context beyond the annotations: the item is taken from the backpack and converted into resource tickets, making clear it is a consuming exchange rather than a read. It says nothing about failure cases (insufficient count, wrong item type) or whether the deposited amount is all-or-nothing, so the disclosure is partial.

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?

A single front-loaded sentence with no filler: action, source, destination and reward in order. The only friction is the unexplained shorthand 'b2-s1..8', which reads as internal notation rather than helpful compression.

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 two-parameter mutation with no output schema, the essential idea (deposit backpack resources for tickets) is conveyed. However, an agent still cannot tell valid item_id formats, what happens on partial or invalid input, or how the ticket payout is computed, which are all real gaps for a consuming trade-in action.

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% — neither item_id nor count is documented in the schema. The description only hints at the item_id domain via the cryptic range notation 'b2-s1..8'; it never explains what item_id accepts nor what count controls beyond the schema's minimum of 1. The description largely fails to compensate for the coverage gap.

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 concrete verb ('Сдать' = deposit/hand over), the resource ('ресурс (b2-s1..8)'), the source ('из рюкзака') and the destination ('на общественный завод'), plus the payout ('в билет ресурсов'). That is a specific verb+resource with a clear outcome. It stops short of differentiating itself from the close siblings game_plant, game_plant_buy and game_plant_make, which keeps it at 4 rather than 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?

There is no explicit statement of when to use this tool versus game_plant, game_plant_buy or game_plant_make, and no prerequisites are given. Usage is only implied by the phrase 'сдать ... на общественный завод', leaving the agent to infer the situation from game knowledge.

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