B3/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered externally. The description usefully adds that results are paginated and that the endpoint is publicly accessible (an auth disclosure), but says nothing about page size, limits, or result ordering behaviour.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single tight sentence with zero filler, and the verb/resource lead is front-loaded. The dangling trailing clause 'Public access.' is clipped but not wasteful enough to hurt placement.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and only annotations covering safety, the description lists the report fields (revision, operation, runtime, permissions) but leaves jargon like 'attributed reports' unexplained and omits pagination mechanics. It is minimally viable for a two-parameter read tool but not fully self-contained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must carry the parameter burden. 'For a path' loosely implies path_id and 'paginated' loosely implies the cursor parameter, but neither is defined — it is unclear whether path_id is an ID, slug, or route, and the cursor's continuation semantics are never explained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Read paginated attributed reports for a path') and enumerates the content types returned (revision, operation, runtime, permissions). It is distinguishable from most siblings, though it never contrasts itself with the very similar-sounding get_path_history.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 tool versus alternatives; with get_path_history, get_filtered_changes and get_operational_outcomes in the sibling list, an agent gets no routing guidance. 'Public access' hints at an auth precondition but is not usage guidance.

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