Api pmbok responsibility matrices partial update

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

Annotations declare readOnlyHint=false and destructiveHint=false, so the agent knows this mutates state but is non-destructive. The description adds nothing beyond that — no mention of what fields are patchable, permission needs, or side effects. No contradiction with annotations, but zero added value.

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?

A single identifier string is technically brief but represents under-specification, not conciseness. Nothing is front-loaded because there is nothing to front-load.

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 a mutation endpoint with a completely undocumented request body, no output schema, and 0% schema coverage, the definition provides no information an agent needs to call it correctly.

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?

Schema description coverage is 0%, so the description must compensate and does not. The 'body' parameter is an untyped anyOf object with no description anywhere, leaving the agent no clue what payload shape a partial update expects.

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?

The description is the tool name verbatim, a tautological restatement rather than an explanation. An agent can infer 'partial update of a PMBOK responsibility matrix' only from the identifier itself, not from any description text.

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?

There is no guidance on when to use this partial update versus the many sibling alternatives (update, retrieve, object_retrieve, matrix_activities/actors endpoints). The 'partial' token in the name implies PATCH semantics but nothing states when that is preferable to a full update.

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