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

No annotations are supplied, so the description carries the full disclosure burden, and it says nothing about whether this is a read-only lookup, whether the fee is global or chain-dependent, whether it requires authentication, or how often it changes. The only behavioral hint, the unit in bps, comes from the same sentence that defines the purpose.

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 or redundancy. It is efficient, though its brevity edges into under-specification for a tool with multiple fee-related siblings.

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 one-optional-parameter read tool with no output schema and no annotations, the core meaning (fee, in bps, per chain) is conveyed. Still missing is whether the fee is per-chain variable, whether the result is a single number or a structure, and any auth or rate-limit expectations.

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 100% and the single chain parameter is fully documented with enum values, a stated default ("bsc"), and a Sepolia exclusion. The description adds no additional meaning about how the chain affects the returned fee, so the schema does all the work.

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?

Names a specific verb and resource ("Get current platform fee") and states the unit (bps), which is concrete enough to know what comes back. It does not differentiate from sibling pricing/status tools such as actora_listing_price, actora_central_subscription_check, or actora_subscription_plans, so an agent must infer which fee source this one reports.

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?

No guidance on when to call this versus the many subscription-related siblings (actora_subscription_check, actora_subscription_detail, actora_central_subscription_check). There are no prerequisites or exclusions stated beyond the schema's own note that Sepolia is unsupported.

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