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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so safety is covered. The description adds a useful behavioral expectation that the output is evidence rather than a compatibility certification, but the "up to 8 mods" cap merely restates the schema's maxItems and nothing is said about the shape or limits of the evidence returned.

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 sentences, no filler, with the capability stated first and the scope disclaimer second. Every clause earns its place.

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 simple two-parameter read tool with full annotation coverage, the safety and scope story is adequate and the absence of an output schema is partly offset by calling the result "published support evidence." Still, with 0% schema description coverage the definition leaves an agent unsure how to format ids and especially what to put in the free-text environment field.

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 both parameters and it largely does not. "Up to 8 mods" loosely maps to ids and "requested environment" loosely maps to environment, but there is no clarification of the id format (a lowercase slug pattern) or of what an environment string should contain — a free-form field of up to 1000 characters that is the single most ambiguous input here.

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 gives a specific verb and resource ("Read published support evidence") plus scope ("up to 8 mods alongside the requested environment"), and it rules out what the tool is not (no project inspection, no certification). It never names or contrasts with the other tools (get_mod_details, search_catalog), so sibling differentiation is inferred from the negative framing rather than stated. "Support evidence" is also somewhat abstract about what is actually returned.

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 exclusion "This does not inspect a project or certify compatibility" is a genuine when-not signal that steers an agent away from treating results as a verdict. However, no alternative tool is named for the cases it excludes, so an agent must guess whether get_mod_details or get_setup_overview is the right fallback.

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