project_access_list_update

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

With no annotations, the description must disclose behavioral traits. It mentions 'POST semantics' but does not explain implications like idempotency, required permissions, or side effects. The agent is left guessing about updates vs. creations and error conditions.

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 description is a single, clear sentence without unnecessary words. It is appropriately front-loaded with the verb and resource. Could be slightly more informative, but it is concise.

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?

Given the tool has a nested array parameter and no output schema, the description lacks details on return values, error handling, or behavior when an entry exists. It does not cover prerequisites or effects, leaving gaps for an agent.

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 baseline is 3. The description adds '(POST semantics)' but no further meaning beyond the schema's 'upsert' hint. The items' fields (ipAddress, cidrBlock, comment) are self-explanatory from the schema.

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 clearly states the action ('Update') and the resource ('IP access list entries for the project'), and adds context with '(POST semantics)' to indicate upsert behavior. This distinguishes it from sibling tools like project_access_list_create and project_access_list_delete.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not explain that this is for upserting entries, nor does it compare to project_access_list_create or project_access_list_delete.

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