get_kb_docs_bulk

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

Annotations already declare readOnly/idempotent/non-destructive, so the description wisely spends its words on behavior instead: the 30-doc cap and the default compact return shape versus full bodies. It does not say what happens if some IDs are invalid or not found, which is the main remaining gap for a fan-out call.

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, both front-loaded: the batching purpose first, then the default-vs-opt-in payload distinction. No restatement of the name or title and nothing that could be cut.

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?

With no output schema, the description correctly carries the return-shape burden by naming compact metadata, chunksPreview, and full content. Only partial-failure semantics for a 30-item fan-out are missing, a minor gap for a read-only tool.

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 already 100%, so the baseline is 3; the description earns above baseline by explaining what includeContent actually changes (full bodies vs. compact metadata plus chunksPreview) and by giving the hard upper bound of 30 on docIds.

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 (fetch KB documents) plus the defining scope: batch/fan-out in one call. It implicitly separates itself from get_kb_doc (single) but never names that or any other sibling, so it stops short of a clean 5.

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?

The phrase 'many KB documents in one call' implies when to use it, but there is no explicit guidance on when to choose it over search_kb_docs or list_kb_docs, nor any exclusion such as search-first-then-bulk.

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