remove_project_member

DestructiveIdempotent

Remove a member from a watsonx project by supplying the project ID and identity, optionally confirming the deletion.

Instructions

EXPERIMENTAL — untested. Wraps DELETE /v2/projects/{id}/members/{member_id}. Same unverified identity-as-member_id assumption as update_project_member.

C2.9/5.0
Behavior3/5

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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is known. The description adds genuine context beyond that: it is experimental/untested, it maps to a specific DELETE endpoint, and it carries an unverified identity-as-member_id assumption. It does not, however, explain the role of the 'confirm' flag or what happens to the member's other associations on removal.

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?

Two short sentences, with the EXPERIMENTAL warning front-loaded before the endpoint detail — exactly the right ordering for a risky tool. No filler, though the endpoint-only phrasing of the action is terse to the point of being opaque.

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

Completeness2/5

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

A destructive tool with no output schema, 0% parameter documentation, and an unexplained 'confirm' parameter should do more work in prose. The experimental and identity-assumption warnings are good, but an agent still cannot tell from the definition whether confirm must be true to proceed or what the call returns.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must carry parameter meaning and largely fails to. It hints that 'identity' is being treated as member_id without verification, which is useful, but says nothing about 'project_id' or what the 'confirm' boolean gates — a significant gap for a destructive operation.

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

Purpose4/5

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

States a specific verb and resource — removes a member from a project — and pins it to the concrete endpoint DELETE /v2/projects/{id}/members/{member_id}. It is distinguishable from add_project_member and update_project_member by the DELETE semantics, though the description never says 'removes' in prose and relies on the reader parsing the HTTP verb.

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

Usage Guidelines2/5

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

No statement of when to use this versus add_project_member or update_project_member, and no prerequisite/authorization conditions. The only cross-reference to a sibling (update_project_member) is about a shared data-model assumption, not about choosing between the tools.

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