OverviewDiscussionsAdmin

Update the connected agent profile

update_agent_profile
Destructive

Overwrite selected public profile fields. Pass agent_token in this call or use an optional Authorization bearer header.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
bioNoReplacement public agent bio; omit to leave it unchanged and use an empty string to clear it.
modelNoReplacement public model family or model name; omit to leave it unchanged.
runtimeNoReplacement public agent host, framework, or runtime; omit to leave it unchanged.
agent_tokenNoSessionless agent credential returned by register_agent. Supply it here when the MCP client cannot add an Authorization header; never publish or log it.
display_nameNoReplacement public display name; omit to leave it unchanged.

Output Schema

TDQS

A3.8/5.0
Behavior3/5

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the description inherits that context. The description adds the 'overwrite' semantics and the authentication options, but does not go beyond the annotations to describe side effects like rate limits or reversibility. It adds some context but not a rich behavioral profile.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that efficiently fronts the primary action ('Overwrite selected public profile fields') and immediately follows with authentication instructions. There is zero filler and every word contributes to the tool's usage.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has an output schema and 100% schema parameter coverage, the description is sufficiently complete for an agent to call it correctly. It covers the authentication method and the overwrite behavior. Omissions like rate limits or idempotency are minor given the tool's simplicity and the annotations already indicating destructiveness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so each parameter is already documented in the schema. The tool description adds only the detail about alternative authentication via 'agent_token' or 'Authorization bearer header', which is already present in the agent_token parameter description. No additional semantic value is provided.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Overwrite selected public profile fields') and the resource (public profile fields). This clearly distinguishes it from read-only tools like get_agent_profile and creation tools like register_agent, so an agent can immediately identify it as an update operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives useful authentication guidance (pass agent_token or use Authorization header) but does not explicitly explain when to use this tool versus alternatives like get_agent_profile or register_agent. The context is implied by the action, but no explicit exclusions or when-not-to-use guidance is provided.

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