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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered. The description adds genuinely new behavioral context not in annotations: the per-call price ($0.01 USDC, x402 on Base mainnet), which matters for invocation, and the liability caveat ('triage guidance, not legal advice') which signals the output is indicative. It does not spell out output structure beyond the summary sentence, but that is acceptable here.

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?

The description is front-loaded with scope and jurisdiction list, then moves to outputs, caveat and price in a sensible order. The country enumeration partially duplicates the schema's country-code parameter, and the specific regulatory acronym list is dense, but each clause carries signal. No filler sentences.

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?

There is no output schema, so the description must indicate returns, and it does: notifiable parties, deadline and computed due time. Payment mechanics and the non-legal-advice caveat are disclosed, which an agent needs before calling a paid x402 endpoint. The only gap is that conditional parameter interplay (sector only for ZA, material/classified_at only for financial institutions) is left entirely to the schema.

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 100%, with every one of the 9 parameters documented in detail, including conditional applicability ('Financial institutions: ...', 'South Africa only', 'ISO 8601; no offset = UTC+2'). The description adds no parameter-level meaning beyond that, so the baseline 3 applies. It also does not state that all parameters are optional or that country drives which other fields matter.

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 the resource precisely (data breach and cyber incident reporting obligations across 11 named jurisdictions) and states what it returns: notifiable regulators/parties, the legal deadline (e.g. 72 hours) and a computed due time from discovery. It also names the specific regimes (POPIA, FSCA/PA, NDPA, ngCERT, Kenya DPA), which no sibling tool covers. The verb is nominal rather than imperative, but an agent can still tell exactly what the tool produces.

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?

Usage is implied rather than stated: an agent infers it is for post-incident triage, and the closing line frames it as 'triage guidance, not legal advice,' which is a useful scope limit. There is no explicit when-to-use/when-not-to-use framing and no named alternative, though no sibling appears to overlap. The default values (country ZA, role responsible_party, sector general) live in the schema rather than the description.

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