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

Annotations already declare readOnly, idempotent, non-destructive, open-world behavior, so the safety profile is covered. The description adds useful behavior beyond that: the data is live from the POPS4 catalogue, priced at wholesale, and returns total, per-head cost, tier band, and follow-up links, plus a named human contact who confirms pricing.

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, front-loaded with the action and the data source, followed by the return shape. The trailing full credential string ('Jenny Huang Goodman MPA MSc MHSA, Principal') is somewhat verbose, but the overall text is efficient for the information conveyed.

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 no output schema, the description does the return-value work by naming total, per head, tier band, and links. Annotations cover safety and openness, so the only meaningful omissions are whether tier has a default and any limits on attendees.

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 0%, so the description must carry parameter meaning; it partially does, since 'per head' hints at how attendees is used and 'tier band' references tier. It never explains tier-level semantics (e.g. what 'bespoke' vs 'whiteglove' means for pricing) or how attendees affects the total, leaving real gaps.

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 concrete verb+resource: it prices a program from the POPS4 catalogue, with a mapping of filing types to program examples. This clearly distinguishes it from the sibling get_* tools, which fetch filing data rather than price offerings.

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 parenthetical examples ('mergers -> welcoming the new team', 'cmo-moves -> a new leader's launch') implicitly tell the agent when this tool applies, and the 'filing' framing implies the trigger context. However, there is no explicit when-not guidance or named alternative for cases where the agent only wants the underlying filing data.

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