  5. First observed

TDQS

A3.5/5.0
Behavior2/5

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

Beyond the annotations (readOnlyHint=false, destructiveHint=false), the description adds no behavioral context such as reversibility, error behavior, or permissions. The agent relies solely on the annotations for safety profile.

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?

The description is a single sentence with no wasted words, front-loading the action and object. It is appropriately sized for a simple tool.

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

Completeness3/5

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

The tool is simple with annotations and full schema coverage, and an output schema exists. However, the description adds no context about when to use it versus tag_link or what happens on removal. It is minimally viable but could benefit from a usage hint.

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?

Since the input schema covers 100% of parameter documentation, the description does not need to explain parameters. The baseline of 3 applies, as the schema already provides adequate semantics for alias, domain, and tag_id.

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?

The description clearly states the action ('Remove') and the resource ('tag from a short link'), making it distinct from the sibling tool tag_link which adds a tag.

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?

The description implies the use case (removing a tag) but does not explicitly mention when to use this tool versus tag_link or other alternatives. No exclusions are stated.

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

A3.9/5.0
Disambiguation5/5

Each tool targets a clearly distinct resource and action: links, domains, tags, auth, and account status are all separate concerns. Even similar tools like shorten_url and bulk_create_links are differentiated by single vs. batch creation, and check_alias is distinct from get_link by checking availability before creation.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern in snake_case (e.g., add_domain, delete_link, list_tags, verify_registration_code). Mixed verb styles like tag/untag and shorten_url are still predictable and fit the established convention.

Tool Count3/5

At 23 tools, the set is on the heavy side and falls in the 16-25 borderline range. The number is somewhat justified by the broad scope (links, domains, tags, auth, analytics), but it approaches the upper limit where an agent may have difficulty selecting between many options.

Completeness5/5

The tool surface covers the full lifecycle of short links (create, read, update, delete, list, stats), domain management (add, delete, verify, list), tags (create, list, delete, tag/untag), and account/auth flows (guest tokens, registration, pro upgrade). It is hard to identify any critical missing operation for the stated purpose.
