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

The annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile needs no restating. The description adds the payload facets (state, balances, claims, audit head), a small but genuine behavioral signal about what the read returns; however, it says nothing about behavior when the bond_id is unknown or about freshness/snapshot semantics.

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?

One front-loaded sentence with zero filler and no redundancy. It is arguably too terse rather than too long—the efficiency is good but achieved by omitting needed detail.

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 return-value documentation is not required, and the safety profile is fully covered by annotations. Still, a read tool keyed on an opaque identifier should at minimum say what an ID looks like and what happens on an unknown bond, which this definition omits.

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 bears the burden of explaining the single bond_id parameter, yet it says nothing about format (UUID, hex, integer) or where to obtain a valid ID. The parameter name is suggestive but undocumented in both schema and description.

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 identifies a specific resource (a bond) and enumerates the returned facets (state, balances, claims, audit head), which distinguishes it from siblings like list_bonds and verify_audit. It lacks an explicit retrieval verb, but 'Current record for a bond' is unambiguous enough for an agent to select it.

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 guidance, no mention of alternatives (e.g., use list_bonds to enumerate, price_bond for valuation), and no prerequisites or error conditions. The agent must infer selection purely from the noun phrase.

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