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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so safety needs no restating. The description adds real value with the 'applied is not published' interpretation warning and the batch ceiling, but it is silent on what happens for unknown or malformed keys (per-item errors vs. whole-call failure) and on partial results.

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 units, no filler, and the batch scope leads. The field enumeration is telegraphic, which suits a lookup tool, though the most actionable sentence (the applied/published caveat) is buried at the end rather than front-loaded.

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?

An output schema exists, so most of the description's text enumerating returned fields is redundant restatement rather than necessary disclosure. Given a single required parameter and a closed-world read, the definition is serviceable, but it leaves the error/partial-result behavior undefined – the one thing an agent calling with up to 50 keys actually needs to know.

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%, so the description must carry the load; it partially does by identifying the array as HL7 Jira keys and repeating the 50-item cap already encoded in maxItems. It does not explain the key pattern ('PROJ-123' style) beyond what the regex implies, nor how invalid keys are handled.

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?

Names the resource (HL7 Jira keys) and the kind of data returned (status, resolution, lifecycle stage, evidence record, citing canonical_url) with a clear batch scope of up to 50. The verb is implied rather than stated ('Up to 50 HL7 Jira keys: status...'), but the operation is unmistakable and clearly distinct from siblings like get_digest_item or validate_bundle.

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 statement of when to use this versus search_digest, get_digest_item, or explain_finding, and no preconditions or exclusions. The closing note '"applied" is not "published"' is a semantic caveat about interpreting results, not usage guidance.

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