create_player_playback_step_forward

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

The description adds no behavioral context beyond the action itself. Annotations already mark it as non-read-only, idempotent, and non-destructive, but the description does not explain side effects on playback position, whether playback must be active, or any error conditions. No contradiction with annotations exists.

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 description is extremely compact: a short semantic label plus the exact HTTP endpoint. Both lines carry useful information, are front-loaded, and contain no filler or redundant prose.

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 zero-parameter call with an output schema and safety-related annotations, the description is minimally viable. It lacks the semantics of 'step' and does not specify when to use it over the many sibling playback controls, which leaves an agent to infer usage from the tool name alone.

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?

The input schema has zero parameters, so there is nothing for the description to document. Schema description coverage is 100% by virtue of an empty properties object, scoring at the baseline for a zero-parameter tool.

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 identifies a clear action and resource: stepping forward in player playback, backed by the explicit POST /player/playback/stepForward endpoint. It does not, however, define what 'step' means (frame, chapter, seconds) or explicitly distinguish itself from sibling playback controls.

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 description offers no guidance on when to use this tool versus alternatives like create_player_playback_step_back, create_player_playback_skip_to, or create_player_playback_seek. There is no mention of prerequisites such as an active playback session or how this differs from other playback navigation tools.

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