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

With no annotations, the description carries the burden of behavioral disclosure. It states that results are cited excerpts with source URLs and notes anonymization behavior for public versus internal keys, which is useful context. It does not explicitly mention auth, rate limits, or side-effect guarantees, but the search/return framing makes the read-only nature reasonably clear.

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?

The description front-loads the core search purpose and is information-dense, but it is long and somewhat repetitive, especially the repeated 'Updata CEO Summit materials' phrasing. It remains usable, but several phrases could be compressed without losing meaning.

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?

Given the broad corpus, multiple source types, and absence of an output schema, the description is fairly complete: it covers corpus contents, source routing, intended first-use priority, and the shape of returned excerpts. It still lacks explicit sibling differentiation and full source-value coverage, which keeps it from being fully complete.

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%, so the baseline is 3. The description adds value by mapping some source enum values to content types, especially source:"doc" for docs, source:"playbook" for playbooks, and source:"resource" for event materials. It does not fully explain study, podcast, case_study, or any, but it meaningfully enriches the source parameter.

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 clearly states a specific verb and resource: searching LeanScale's full knowledge corpus. It enumerates the source types and explains the difference between docs and playbooks, but it does not explicitly distinguish this tool from siblings such as search_podcast, get_playbook, or get_case_study.

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?

It gives clear usage guidance with 'Use this first for any go-to-market, RevOps, sales-ops...' and explains when to pass source:"doc", source:"playbook", or source:"resource". It does not state when to avoid this tool in favor of specific sibling retrieval tools, so it falls short of full when/when-not/alternatives guidance.

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