Get Title Context

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true. The description adds the important behavioral context of being 'subscription-gated', which is not in the annotations. This helps the agent understand access constraints. No contradiction with annotations.

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 sentence of 7 words, extremely concise with no wasted text. Every word adds value: 'Fetch' indicates the action, 'safe' and 'subscription-gated' add constraints, and 'context for a game title' defines the resource.

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?

The tool is simple with one optional parameter and no output schema. The description adequately covers the purpose and constraints, but does not explain what the returned context contains (e.g., settings, status). Given sibling tools and the lack of output schema, a bit more detail would improve completeness.

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 100% for the single parameter, with a clear description in the schema itself. The tool description adds no additional meaning beyond what the schema provides for title_id. 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 clearly states the tool fetches context for a game title, using the verb 'Fetch' and specifying 'safe, subscription-gated context'. It distinguishes from siblings like glitch_list_titles and glitch_select_title by focusing on context retrieval rather than listing or selection. However, it could be more specific about what 'context' includes.

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 does not specify when to use this tool versus alternatives like glitch_list_titles or glitch_select_title. It mentions 'subscription-gated' as a condition but lacks explicit guidance on when to invoke or avoid this tool, and no alternatives are listed.

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