plex_media_enrichment

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

The readOnlyHint annotation already signals a non-mutating operation, and the description adds a return format and an example call. However, it does not disclose per-operation behavior, potential side effects, external service dependencies, rate limits, or the structure of the returned data beyond a generic string.

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 fairly compact and includes useful return-format and example sections. However, the 'PORTMANTEAU PATTERN RATIONALE' section is redundant filler, and the phrase 'High-value' adds subjective noise without practical information.

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 three distinct operations and no output schema, the description only provides a generic return format and one example. It does not explain the behavior of get_external_metadata or analyze_trends, making the tool only partially complete for a multi-operation interface.

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?

All four parameters already have schema descriptions, so the bar for added value is lower. The example supplies a concrete call pattern (operation='enrich_item', title='Inception', year=2010), but the three enum operations are not explained individually, leaving the agent to guess what 'analyze_trends' or 'get_external_metadata' do.

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 clearly states the tool is for 'media enrichment using external sources (Wikipedia, TMDB, TVDB)' and explains it adds 'Informed Discovery capabilities' by fetching contextual metadata. This distinguishes it from sibling tools like plex_metadata, though the exact meaning of 'enrichment' remains somewhat abstract.

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 implies usage when external metadata beyond Plex's native data is needed, naming specific sources and noting that Plex does not natively provide this. However, it offers no explicit guidance about when to prefer this tool over alternatives like plex_metadata or plex_rag, nor any exclusions.

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