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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds only the endpoint path and the word 'paginated', with no ordering, auth, rate-limit, or page-indexing behavior disclosed.

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 clauses, front-loaded with the purpose and then the endpoint. Nothing redundant or padded; every token serves the reader.

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 paginated listing endpoint, critical invocation details are absent: whether 'page' is 0- or 1-based, default behavior, and what the pagination envelope looks like. Only the enum source and the limit cap are resolvable, and the absence of an output schema means the description could have done more.

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 67%: 'limit' is documented in the schema (max 100, capped) and 'source' has an enum plus label, but 'page' has no description anywhere. The description adds nothing about parameter meaning beyond the implied source filter, so it does not compensate for the 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?

States a specific verb and resource ('Get paginated signal logs') and narrows scope with 'by source', plus the raw endpoint. It is interpretable and roughly distinguishes it from get_log_signal_paginated (all sources), but it never names that sibling or get_log_signal_source_id_paginated, so the differentiation is inferential rather than explicit.

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 when-to-use guidance, no prerequisites, and no mention of the closely related alternatives (get_log_signal_paginated, get_log_signal_source_id_paginated). The agent must infer from the name alone which of the several paginated log endpoints to pick.

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