get_bookmark_content

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

No annotations are provided, so the description carries full burden. It states the output is in Markdown format and implies fresh content from the URL. It also tells the agent to summarize. However, it does not disclose whether the tool is read-only, destructive, requires authentication, or has rate limits. The overall behavior is clear but could be more explicit about safety.

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 reasonably concise at about six lines. It front-loads the main purpose and includes helpful usage guidance. However, it contains meta-instructions to the agent ('you will summarize') which adds some redundancy. Still efficient overall.

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 one parameter, high schema coverage, and an output schema, the description is fairly complete. It covers the output format (Markdown) and various use cases. It lacks error handling details or prerequisites, but given the output schema likely documents return values, it is adequate.

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 only parameter 'id' is described in the schema as 'The bookmark ID' with 100% coverage. The description does not add extra meaning beyond the schema, such as how to obtain the ID or its format. Baseline is 3 due to high schema coverage.

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 gets the full content of a bookmark in Markdown format. It uses a specific verb ('Get') and resource ('bookmark content'), and distinguishes from siblings like 'get_bookmark' (which likely returns metadata) by specifying it returns full article content.

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 explicitly lists when to use the tool: reading full article, getting a summary, analyzing or discussing content, quoting parts, or getting fresh content from the URL. It also instructs the agent to summarize after calling. However, it does not mention when NOT to use or mention alternatives like 'get_bookmark' for metadata.

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