update_coffee_profile

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

With no annotations, the description carries the full behavioral burden, yet it discloses almost nothing: no auth/permission requirements, no statement of whether it merges with or replaces existing profile fields, and no indication of what happens to unspecified fields. The phrase 'make themselves available for networking' hints at an effect but is not a behavioral contract.

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?

A single front-loaded sentence with the verb and resource stated first. Minor redundancy in the trailing purpose clause ('to make themselves available for networking'), but no waste that harms readability.

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 mutation tool with six parameters, zero annotations, and no output schema, the description is too thin. It never explains upsert semantics, whether all fields are optional-by-default (the schema requires none), or what a caller should send to just toggle availability. An agent lacks enough context to invoke it confidently.

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 six parameters (bio, headline, industry, help_topics, is_available, years_experience) are already fully documented in the schema. The description adds no additional meaning beyond that. Baseline 3 applies when the schema does the heavy lifting.

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 (create/update) and a precise resource (the user's coffee chat profile), which is distinguishable from the general profile tools (update_profile_basic, update_full_profile) and the coffee-chat read tools. It does not explicitly route against siblings, but the resource naming is specific enough for an agent to pick it apart from get_my_coffee_profile or delete_coffee_profile.

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 indication of when to use this versus alternatives such as update_full_profile or get_my_coffee_profile, and no prerequisites are stated. There is no when-not guidance and no mention of reading an existing profile first. The agent is left to infer usage 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.
