pr_setInOut

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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false, so the safety profile is covered. The description clarifies that the tool can both set and clear, but doesn't say whether in/out points affect export ranges or playback, or what happens if no points are supplied.

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 no filler. It is compact to the point of slight compression ('with item'), but nothing 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?

Five optional parameters, no output schema, and no annotations about defaults mean the description should clarify behavior when no arguments are given or when clear is combined with points. It covers the two targeting modes but leaves call-time ambiguity for an all-optional schema.

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 coverage is 60%; inPoint/outPoint and sequence are already documented in the schema. The description adds real value by explaining that 'item' switches the target from the sequence to a project item's source, but says nothing about how 'clear' interacts with inPoint/outPoint, which is the key ambiguity given 0 required params.

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 ('set (or clear) sequence in/out points') and distinguishes the alternate mode (a project item's source in/out via 'item'). The scope shift from sequence to source-item is graspable, though 'with item' is terse enough to require a re-read.

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 parenthetical 'or clear' and 'with item' imply the two modes of use, but there is no explicit guidance on when to prefer this over siblings like pr_setPlayhead, pr_removeRange, or pr_trimClip, nor on prerequisites (e.g., must a sequence be active?).

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