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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and a closed-world scope, so the safety profile is covered. The description adds one genuinely behavioral detail beyond that: the embed snippet is only present when the agent is published, a conditional return state. It does not mention permissions, errors, or size of the returned config.

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 purpose is front-loaded in the first clause with no preamble or filler. The one-sentence enumeration is long and repetitive ('its ... its ...'), and the clause 'where the owner previews and publishes it in Agent One' is awkwardly worded, but nothing is truly extraneous.

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, the description need not restate return values, and annotations cover the safety profile, leaving little required. For a one-parameter read tool this is close to complete; only the missing when-to-use steering against sibling tools keeps it from a 5.

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 100% for the single agentId parameter, and the schema itself already says 'Agent ID from list_agents.' The description adds no additional meaning about the identifier, the max length, or what happens with an invalid or unpublished ID, so the baseline of 3 applies.

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 opens with a specific verb and resource ('Get one agent's configuration') and enumerates the concrete contents returned: instructions, greeting, knowledge sources, lead form state, totals, publishUrl, and embed snippet. This clearly separates it from list_agents (singular vs. list), though it does not explicitly name any sibling tool as an alternative.

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 explicit statement of when to call this versus get_agent_insights, list_agents, or get_profile. Usage is only implied by the enumerated payload, which lets an agent infer 'call this when you need the full config of a single agent' but leaves exclusions and prerequisites unstated.

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