First observedApr 15, 2026

TDQS

A3.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description's read/write split reinforces that and points to org_manage, but adds nothing about pagination, default time windows, or permission requirements for the org-scoped reads.

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 sentences, no filler, with the read scope and the org_manage handoff front-loaded. The middle clause is a dense keyword list rather than prose, which is efficient but slightly reads as a dump of action names.

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

Completeness3/5

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

For a 16-parameter, 22-action multiplexed tool with no output schema, the description gives the agent a category map but no per-action requirements (which actions need org_id, meter, or workspace_id) and no return-shape hints. The `describe` action in the schema partially compensates, so this is adequate but not complete.

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% and every parameter (detail defaults, meter, starting_after, describe_action, workspace_id scoping) is already documented inline. The description only repeats the action category names, adding no format, default, or interaction semantics beyond the schema. Baseline 3 is correct.

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 the resource (Fastio organizations) and the read-only scope, then enumerates the operation families (list, details, limits, workspaces, shares, billing, members, invitations, discovery, assets) that map onto the 22-value action enum. That is enough to tell it apart from org_manage, though it never names a single verb+resource pair per action.

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?

Explicitly routes write operations to the sibling `org_manage`, which is a genuine when-not rule. It does not, however, say when to pick a specific action over another (e.g. details vs public-details, discover-all vs discover-available), leaving that to the schema's 'describe' action.

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