Create a page-view tracker

create_tracker

Create a free page-view tracker for a website. Returns the tag image URL and ready-to-paste snippets for the site's pages, plus the stats URL where views, visitors, pages and referrers are shown. When signed in, the tracker belongs to the account; otherwise keep the manage_token to claim it later.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4/5.0

Behavior4/5

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

Annotations cover the mutation/safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false), so the description's job is to add context — and it does, disclosing that the response includes the tag image URL, paste-ready snippets, and a stats URL, plus the auth-dependent ownership behavior and the need to retain manage_token. That is real behavioral detail beyond the annotations, though rate limits and token lifetime are unstated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences, front-loaded with the core action and then the return payload and ownership rule. Every sentence carries information an agent needs.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description usefully explains what comes back (tag URL, snippets, stats URL) and how ownership works. It stops short of clarifying how the manage_token is surfaced in the response or any creation constraints, but it is otherwise sufficient for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents both name and site_url (including the domain/subdomain counting rule), making 3 the baseline. The description adds no parameter-level meaning beyond that.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb+resource ('Create a free page-view tracker for a website'), which is clearly distinguishable from siblings like shorten_url, generate_qr and get_stats_url. The scope (page-view tracking on a website) is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the creation framing, and the description adds useful context about signed-in vs anonymous ownership, but it never states when to prefer this over an alternative tool or what preconditions must hold before calling it. No explicit exclusions or alternatives are named.

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