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

Annotations already provide readOnlyHint=false, openWorldHint=true, and destructiveHint=true. The description adds value beyond these by enumerating concrete risky operation classes (delete, revoke, cancel, send, activate retention) and disclosing a genuinely new trait — 'Not automatically undoable' — plus the confirmation-before-call requirement. No contradiction with annotations; the description's claims align with all three hints.

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?

Compact at roughly 52 words across four sentences, and the most critical information ('DESTRUCTIVE') is front-loaded in caps, followed by consequences and the confirmation requirement. Minor redundancy: 'reaches people outside this system' and 'May reach systems outside PaperOffice' communicate the same open-world trait twice.

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?

For an open-world dynamic dispatcher with an unrestricted arguments object, the description covers the danger profile thoroughly but leaves operational gaps: how arguments should be shaped for a given tool_id, how to discover valid tool IDs (despite schema/search siblings existing), and the explicit read-vs-write split with call_read. An output schema exists, so return-value documentation is not the description's responsibility.

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?

With 0% schema description coverage, the description carries the burden for both parameters, but only nominally addresses tool_id (it selects an inner tool in the connector universe, which is something beyond 'string'). The arguments parameter — a free-form passthrough object with additionalProperties — receives zero explanation, and there is no pointer to sibling tools po_mcp_tools_schema or po_mcp_tools_search for discovering valid tool_id values.

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?

Description states a specific verb+resource: 'Execute any inner tool_id in this connector universe, including writes.' The title's '(writes allowed)' framing differentiates it from its read counterpart, po_mcp_tools_call_read, which appears directly in the sibling list. Clear overall, though the description body never names the read sibling explicitly.

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?

The destructive framing ('Not automatically undoable — confirm intent first') implies this is for write operations requiring user confirmation, which is useful. However, there is no explicit routing guidance: it never states 'use po_mcp_tools_call_read for read-only calls' or gives when-not-to-use conditions. Usage context is implied by the title and danger warnings rather than stated.

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