remove_circle_member

Destructive

Remove a member from a Circle, deleting their channels and revoking any live authorizations routed through them. Requires a Proof account with PROOF_API_KEY configured.

Instructions

Remove a member from a Circle. Deletes the member's channels and revokes any live authorizations that routed through them.

ACCESS: needs a Proof account. Set PROOF_API_KEY and restart this server, then call this tool again. start_login does NOT open this tool.

TDQS

A4.4/5.0
Behavior5/5

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

Annotations already declare destructiveHint=true, but the description goes further by specifying exactly what is destroyed: the member's channels are deleted and live authorizations routed through them are revoked. It also discloses the auth prerequisite and its operational remedy, which no structured field provides.

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

Conciseness4/5

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

Front-loads the action and its side effects in two tight sentences, then separates the access requirement into a clearly marked block. The restart instruction borders on operational noise but is actionable for resolving the failure, so it largely earns its place.

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

Completeness5/5

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

Output schema exists, so return values need no explanation. For a destructive, cascading removal with an authentication gate, the description covers the mutation, its blast radius, and the prerequisite — everything an agent needs to call it safely.

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?

Both parameters are fully described in the schema (100% coverage) as Circle ID and Member ID, so the schema does the heavy lifting. The description implies the member's channels are scoped to that member but adds no format, constraint, or identifier-matching detail beyond the schema, making the baseline 3 correct.

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?

States a specific verb and resource ('Remove a member from a Circle') and immediately clarifies scope by naming the cascading effects on that member's channels and authorizations. This is distinguishable from siblings like add_circle_member and remove_circle_member_channel without opening any schema.

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

Usage Guidelines4/5

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

Gives an explicit precondition for use (requires a Proof account via PROOF_API_KEY and server restart) and preempts a likely wrong path by stating that start_login does NOT unlock this tool. It does not name sibling alternatives such as removing only a channel, but the context for when this tool applies is clear.

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