trakt_sync_to_trakt

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

Annotations already indicate readOnlyHint=false (write operation) and destructiveHint=false. The description adds no additional behavioral context such as authentication requirements, rate limits, side effects, or what happens to existing Trakt data. It merely restates the action without elaborating on consequences or prerequisites.

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 a single, front-loaded sentence that fully conveys the core purpose without any wasted words. It is an example of efficient, minimal writing that earns its place.

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 sync tool with no output schema and annotations that are not rich (only readOnlyHint/destructiveHint/openWorldHint), the description is too sparse. It does not explain the sync process, whether authentication is required, what a 'sync' entails (e.g., one-time vs. continuous, full vs. incremental), or what the expected outcome/return is. This leaves significant gaps for an agent invoking the tool.

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 schema description coverage is 100%, with each parameter (dryRun, batchSize, includeProgress) clearly described. The description does not add any parameter-specific meaning beyond what the schema already provides, so a baseline score of 3 is appropriate.

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 'Sync Plex watch history to Trakt.tv' uses a specific verb ('Sync') and explicitly names the source (Plex) and destination (Trakt.tv), clearly distinguishing it from the sibling tool trakt_sync_from_trakt which syncs in the opposite direction.

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 directional phrasing 'Plex to Trakt.tv' makes the intended use clear and implicitly contrasts with trakt_sync_from_trakt. However, it does not explicitly state when to use this tool over alternatives or mention exclusions, though the sibling context provides sufficient differentiation.

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