create_link

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

No annotations are provided, so the description carries the full burden, yet it discloses only that this is a mutating create. It does not mention auth/permission requirements, slug-uniqueness or collision behavior, whether the slug is used as a redirect path, or what the response contains (no output schema). 'Tracked' hints that the link records analytics events, which is the only real behavioral signal.

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?

It is a single front-loaded sentence with no filler, so there is no verbosity problem. The issue is the opposite: it is under-specified rather than concise, so the brevity earns no more than a middling score.

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 four-parameter mutation tool with zero annotation coverage, no schema descriptions, and no output schema, the definition leaves the agent without enough information to call it correctly. Missing are required-parameter semantics, slug rules, teamId scoping, error/conflict behavior, and return shape.

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 description coverage is 0% and the description names none of the four parameters. The agent gets no meaning for url, name, slug (length constraints only), or the optional teamId, and no indication that slug is constrained to 8-100 characters and must presumably be unique.

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?

'Create a tracked link' states a specific verb and resource, and the resource (link) is distinguishable from sibling creators like create_pixel, create_website, or create_share. It stops short of 5 because it says nothing about scope (team vs. personal) or how it differs from the closest siblings, list_links/get_link/update_link.

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?

No when-to-use guidance at all: no prerequisites (e.g., must provide a slug not already taken), no indication of whether teamId is needed for team-scoped links, and no pointer to alternatives such as create_website_share or send_link_or_pixel_event. The agent must infer usage entirely from the sibling list.

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