A4.5/5.0
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true. The description adds useful context beyond that by stating it returns the latest chain block height and is used for goodTilBlock math. No behavioral contradictions are present.
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?
The description is extremely concise: two sentences that convey the purpose and a use case. Every word earns its place with no fluff or redundancy.
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?
Given the tool has no parameters, annotations provide readOnlyHint=true, and there is no output schema, the description is fully complete. It explains what the tool does and why it's useful, which is sufficient for an agent to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0 parameters, so the baseline score is 4. The description does not need to add parameter information, and it does not attempt to invent any. This is appropriate.
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?
The name and title clearly state 'get_block_height' and 'Get latest block height'. The description specifies it returns the latest chain block height, which is a specific verb and resource. Among siblings, no other tool retrieves block height, so it is well-distinguished.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear use case: 'Useful for SHORT_TERM order goodTilBlock math.' This gives context for when to use the tool. However, it does not explicitly state when not to use it or mention alternative tools, but given the simplicity and uniqueness of the tool, this is acceptable.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.7/5.0
Disambiguation3/5
Most tools are clearly distinct, but there is overlap among the read-heavy account tools: get_balance/get_funding_status/fund virtually duplicate each other, and get_equity/get_portfolio/get_position_risk/get_open_orders/get_positions all converge on equity and open-position data. The detailed descriptions help an agent choose, but several tools have fuzzy boundaries.
Naming Consistency4/5
The overwhelming majority follow the expected verb_noun convention: get_*, place_*, cancel_*, close_*. Minor deviations such as batch_cancel, get_candles_multi, top_up_gas, and whoami make the pattern not perfectly uniform, but the inconsistency is small.
Tool Count2/5
At 33 tools, the surface is beyond what most agents need and includes several redundant query helpers rather than genuinely distinct operations. A broad exchange can justify a large surface, but get_balance/get_funding_status, get_equity/get_portfolio/get_position_risk, and get_candles/get_candles_multi make the set feel top-heavy.
Completeness4/5
The core lifecycle is well covered: market discovery, market data, order placement/cancellation, position management, risk, funding transfers, PnL, and account status. Obvious gaps are limited to historical order lookup by order ID, a way to cancel across all markets in one call, and a few optional account-history conveniences.
