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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds two genuinely new facts: the state is PII-free, and project_key functions as a capability handle (an access credential). It does not disclose failure behavior for an invalid or rotated key, which is the key remaining gap.

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 front-loaded sentence with the verb first and zero filler. It is arguably too terse for the amount of undocumented parameter surface, but nothing in it is wasted.

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?

There is no output schema, so the description should hint at what 'project state' contains, and it does not. Annotations cover the read/idempotent profile, but an agent still lacks guidance on return shape and on what happens when the capability handle is rejected.

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 carry the semantics. It correctly frames project_key as a 'capability handle' rather than a plain lookup key, which is meaningful, but says nothing about the format or source of project_id, nor how the 40-120 character key is obtained.

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?

States a specific verb and resource ('Read persistent PII-free project state'), which clearly separates it from write-oriented siblings like workspace_create_project or workspace_update_intake. It does not explicitly name a sibling it is not, and 'state' remains somewhat abstract, 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?

There is no statement of when to use this versus workspace_describe, workspace_review_readiness, or workspace_get_handoff. The only usage signal is the implicit prerequisite of supplying both project_id and project_key; no exclusions or alternative routing are given.

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