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

No annotations are supplied, so the description carries the full behavioral burden. It implies a read-only verification but never states that it is side-effect free, what a failure result looks like, whether an invalid chain raises an error or returns a partial report, or what the expense of scanning the full log is. Given a zero-annotation mutation-adjacent tool, this is a significant gap.

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 front-loaded sentence with no filler, and the core verb plus scope arrive immediately. The parenthetical '(production)' is slightly cryptic and the jargon ('linkage') is unexplained, but there is no wasted wording.

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 verification tool with no annotations, no output schema and one undocumented parameter, the description should say what result the caller gets back and how failure is signalled. Instead it stops at the operation name, leaving the agent without the information needed to interpret a response or decide between the adjacent verify 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 coverage is only 50%: 'session' is fully documented inline, but 'checkpointsOnly' has no schema description at all. The phrase 'full log and checkpoint chain' faintly suggests the flag restricts verification to checkpoints, but the description never confirms this or explains the trade-off, so it does not compensate for the coverage gap.

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 scope: 'verify signatures + linkage over full log and checkpoint chain'. That is materially more informative than the tool name alone, and the 'full log and checkpoint chain' phrasing hints at how it differs from a lighter resume verification. It never names a sibling or states the boundary explicitly, so an agent must infer the distinction from names alone.

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?

No when-to-use or when-not-to-use guidance. The '(production)' tag implies an environment constraint but is never explained, and there is no indication of when this full-chain check should be preferred over edna.id.verify_resume or edna_identity_verify, nor any prerequisite or cost warning for a full-chain scan.

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