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

Annotations already declare the read-only, idempotent, closed-world safety profile, yet the description adds substantive behavioral caveats not present anywhere in structured fields: no live availability, no safety certification, integrations untested, and that results include vendorTestingPolicy. This is meaningful scope disclosure, though it says nothing about errors, auth, or rate limits.

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?

Front-loads what the tool does before the caveats, and each clause adds a distinct nuance (availability, safety, integration testing, protocol tests). There is mild redundancy across the last three sentences on the 'untested/uncertified' theme, which keeps it from a 5.

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?

No output schema exists, so the description carries more burden for return values; it names vendorTestingPolicy as a result field but does not otherwise characterize the returned detail, provenance, or sources. Adequate for a two-parameter lookup, but the return shape remains thin.

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 50%: the language parameter is richly documented in the schema, but the required id parameter has no description anywhere, and the tool description never mentions it (format, source, or lookup expectations). At this coverage level the description needed to compensate and does not.

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?

Specific verb 'Read' plus a concrete resource set (software details, provenance, sources, documentation review scope). An agent can tell this is a detail-lookup tool, but it never contrasts itself with search_software or compare_software, so sibling differentiation is left 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?

The description explains what the data means (docs-reviewed only, no certification) but gives no when-to-use instruction and never routes to an alternative such as search_software for discovery or get_review_summary for reviews. Usage is only inferable from the required id.

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