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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds one genuine behavioral detail beyond the annotations: results are scoped to requests "the caller can open," implying permission-based filtering. It says nothing about ordering, page size defaults, or whether archived specs are included.

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?

The single sentence is front-loaded and free of filler, which is good, but for a four-parameter paginated list tool the brevity crosses into under-specification rather than conciseness.

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?

With no output schema and no parameter documentation, the description should carry more weight for a list tool: what fields come back, how to page through results, and how the archived and project_id filters behave are all missing. Only the permission-scoping hint is provided.

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% across four parameters, and the description compensates for none of them. It never explains whether "archived" includes or excludes archived specs, how cursor/limit pagination behaves, or what project_id scoping does.

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 gives a specific verb ("Lists") and resource ("saved requests"), and usefully glosses the opaque tool name "specs" as saved requests. It falls short of 5 because it does not distinguish the result set from closely related listers such as list_request_templates, list_starred, or list_spec_revisions.

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 when-to-use guidance, no mention of alternatives for retrieving specs (get_spec, list_spec_revisions, search_workspace), and no note on when to prefer this over filtering elsewhere. Only the implicit hint that results are limited to what the caller can open.

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