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

Annotations only declare write/openWorld/non-destructive; the description adds genuinely useful behavior: the offer becomes publicly visible to buyers, confirmation is on by default and toggleable, and a Cotlet API key with app access is required. That is real context beyond the annotation set, though it does not describe reversibility or what happens after publishing.

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 purpose is front-loaded well, but the public-reach/confirmation point is repeated three times across separate sentences ('it asks first,' 'you confirm each call,' 'confirm with the user before each call'), which is redundant padding rather than concise emphasis.

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 3-parameter write tool with no output schema and annotations already covering the safety profile, the description supplies the key remaining context: public visibility, confirmation requirement, and auth needs. It is essentially complete, with only minor gaps around post-publish behavior or editability.

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 the schema already documents title, description, and price. The description merely restates those same three fields ('with a title, description and price') without adding format, currency, or validation nuance beyond what the schema supplies, matching the baseline of 3.

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 states a specific verb and resource: 'Publish a fixed-price Offer on your profile,' with the inputs (title, description, price) named. It is clearly a create/publish action and distinguishable from sibling reads like peopleperhour_list_offers, though it never explicitly names a sibling to route against.

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?

It tells the agent that this reaches the public and therefore requires per-call confirmation, which is implied usage context. However, it offers no explicit when-to-use/when-not guidance or comparison against alternatives such as send_proposal, so an agent must infer positioning from the name alone.

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