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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds genuinely useful context beyond that: the returned fields (workspace_id, workspace_name, framework, user_role, can_write, can_vote_and_comment) and what the permission flags mean. It stops short of describing pagination behavior despite the cursor/limit design.

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?

Purpose is front-loaded in the first clause and the dense field-semantics sentences earn their place given there is no output schema. It is a little heavy in run-on enumeration but contains no filler or redundant restatement of the title.

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 read-only list tool with annotations covering the safety profile, the description compensates for the absent output schema by enumerating the meaningful returned fields and permission flags. The main gap is that pagination (the limit/cursor mechanism) is never addressed, which an agent needs for exhaustive listings.

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% for the two parameters (limit, cursor), so the description must compensate and does not — neither limit nor cursor is mentioned or explained. The field names it does discuss (framework, user_role, can_write) are response attributes, not input parameters, so they add no input guidance.

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 ('List accessible projects across all workspaces') and immediately scopes it as a cross-workspace listing. It references the sibling hypotize_project_get for field semantics, which helps an agent relate the two, though it does not explicitly frame the singular/plural retrieval distinction.

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?

No when-to-use, when-not-to-use, or alternative-selection guidance is given. The description never tells the agent to prefer this over hypotize_project_get for single-project retrieval or how it relates to other list tools like hypotize_frameworks_list; usage is only inferred from the verb 'List'.

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