Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With readOnlyHint=true already provided, the description adds value by specifying the returned fields (title, body, author, clinical reviewer, citations, metadata). This gives the agent a clear expectation of the output without over-explaining.
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 two concise sentences, front-loaded with the primary purpose, followed by the return format. Every word is useful and there is no redundancy.
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 simple read-only fetch tool with one parameter and no output schema, the description fully covers what the tool returns and how to call it. No critical information is missing.
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 already covers the 'slug' parameter with a description. The description mentions 'by slug' but adds no additional meaning beyond what the schema provides, so the baseline of 3 applies.
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 action ('Fetch a single article'), the resource ('a single article from Therapy for Teens'), and the method ('by slug'). It naturally distinguishes itself from sibling tools like list_articles and search_articles by emphasizing the singular, slug-based retrieval.
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 the appropriate scenario: when you have a specific slug and need one complete article. It does not explicitly mention alternatives or exclusions, but the contrast with list/search tools is evident from the phrasing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Each tool serves a distinct purpose: fetching a single article, listing articles, searching, citing, retrieving crisis resources, and getting site info. There is no overlap or ambiguity between them.
All tool names follow a consistent verb_noun snake_case pattern (cite_article, get_article, list_articles, search_articles, etc.). The verbs accurately describe the action and the nouns are clear.
Six tools is appropriate for a read-only content library. Each tool covers a necessary functionality (list, search, get, cite, plus safety and context) without unnecessary bloat or missing essentials.
The tool surface fully covers the core domain of accessing articles: listing, searching, retrieving, and citing. The addition of crisis resources and microsite info completes the lifecycle for a safe, well-rounded library. No obvious gaps.
