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

Annotations already mark this as a non-read-only, non-destructive, non-idempotent write. The description adds genuinely useful behavioral context beyond that: the permission thresholds required for the default (active) mode versus the relaxed requirements for proposal mode. It does not mention that proposal creation is idempotent (that detail lives only in the schema), which keeps it from a 5.

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?

Two sentences, zero filler, with the core action front-loaded and the permission nuance following. Every clause carries information an agent needs.

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 6-parameter mutation tool with low schema coverage and no output schema, the description covers permissions and creation mode but leaves the structural parameters (parentId placement, ownerLabel) unexplained. Adequate but with clear gaps for an agent choosing argument values.

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 only 33% across 6 parameters, so the description should compensate. It only clarifies creationMode's active/proposal distinction (largely duplicating the schema's own description) plus the permission implications; parentId, ownerLabel, name, and orgId meaning are left undocumented. Marginal added value over the schema.

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?

"Create an area folder in the process tree" gives a concrete verb and resource and clarifies that the node is an area/folder concept, which helps separate it from siblings such as createClarityProcessNode and createClarityFolder. It does not explicitly name which sibling to prefer, so it stops short of a 5.

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 description gives conditional context — active mode needs org admin+/manager+, proposal mode is open to any member — which implies when each mode applies. However it never states when to use this tool versus alternatives like proposeClarityLandscapeProcess or createClarityProcessNode, so usage guidance is implied rather than explicit.

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