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

Annotations only declare the safety profile (readOnly=false, destructive=false, idempotent=false); the description adds real behavioral context beyond them: expiry semantics ('visitors then see 'link expired''), slug auto-generation for unguessable tokens, and per-link inheritance of greetings/themes. It does not describe the delete action's consequences or list pagination behavior, so not a 5.

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?

Front-loaded with the core purpose, then usage rationale, then return values, with zero filler sentences. The return-value paragraph slightly duplicates what the output schema already carries, which is the only wasted space.

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 14-parameter multi-action tool, the description supplies the mental model an agent needs (link = URL + QR + presentation mode with per-link overrides) and defers per-parameter detail to a fully-covered schema and a return-value output schema. Deletion consequences and pagination are the only gaps, and those are minor.

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 100%, so each of the 14 parameters is already documented in the schema, including action-to-required-parameter mapping and enum meaning. The description adds only the conceptual model (a link carries greeting/topic/caption/theme/expiry) rather than new per-parameter syntax, so the baseline 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?

States a specific verb and resource up front ('Create and manage shareable links for an agent') and immediately grounds it with the concrete artifact produced (unique URL, QR code, chat vs conversation rendering). An agent can distinguish this from sibling tools like gnosari_manage_appearance or gnosari_manage_access without inspecting either schema.

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?

Strong contextual guidance on why multiple links exist ('one link per channel (poster, email campaign, personal invitation) so each is tracked separately'), which tells the agent when to create several links rather than reuse one. It does not explicitly name alternatives or state prerequisites (e.g., that the target agent must already exist) or when to prefer get/list over create, so it falls short of a 5.

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