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

Annotations already establish the full safety profile (readOnlyHint, idempotentHint, destructiveHint=false, openWorldHint=false), so the bar is lower. The description usefully adds that verification is against a 'signed canonical catalog' (i.e., cryptographic/authoritative rather than best-effort), but says nothing about what a failed verification yields or whether network/auth is involved.

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?

A single tight sentence with the verb and resource front-loaded and zero filler. Nothing could be removed 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?

With an output schema present, return values need not be explained, and the annotations cover safety. For a two-parameter, single-purpose verification tool the description is nearly sufficient; the only real gap is the lack of routing guidance versus the sibling discovery/search tools.

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 semantic load. It does map both inputs conceptually ("asset identifier or content hash"), clarifying that either asset_id or content_sha256 can be supplied, but the 'or' relationship and the format constraints (the regex patterns) are only inferable from the schema.

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 names a specific verb ("Verify") and a specific resource ("an AgentiScript asset identifier or content hash") plus the authority it checks against ("the signed canonical catalog"). This clearly distinguishes it from read/list siblings like discover_assets or search_catalog, though it names no sibling explicitly.

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 when-to-use or when-not-to-use guidance and no alternative is referenced, despite six siblings that also touch assets. The agent must infer that this is the validation step to run before trusting an asset discovered via discover_assets or search_catalog.

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