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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing behavioral beyond restating the HTTP route: no mention of what is returned, what happens when no bot matches the pair, or whether the signal bot must be owned/accessible.

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 short sentences, front-loaded with the purpose, with no filler. The appended raw endpoint path adds little value for an agent and is the only wasted token.

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 read tool with two required, undescribed parameters and no output schema, the description should say what a successful response contains and how failures (unknown chain/address) surface. Neither is addressed, leaving the agent unable to predict behavior.

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% and both parameters are required and undocumented, so the description carries the full burden. It only echoes the parameter names conceptually ('chain and address') and gives no format guidance, e.g. whether chainId is a numeric string, a slug, or that address must be the bot's on-chain address.

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?

States a specific verb ('Get') and resource ('DEX signal bot') along with the lookup key ('by chain and address'), which sets it apart from the ID-based sibling get_bot_signal_dex_id. However, it never explicitly names that sibling or the folder/total variants, so differentiation is only implicit.

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 when-to-use or when-not-to-use guidance, and no alternatives are named despite a dense cluster of near-identical get_bot_signal_dex* tools. The 'by chain and address' phrasing hints at the selector but leaves the agent to infer when this tool beats get_bot_signal_dex_id or get_bot_signal_dex_factory_chainId_exchangeId.

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