acknowledge_observation

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

Beyond the annotations, the description discloses a meaningful side effect (uncertain pauses the session) and a non-effect (never a send receipt). It does not cover auth, reversibility, or error behavior, but annotations already cover the destructive/read-only profile.

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?

Two short sentences carry all essential information with no filler. The outcome values are front-loaded, followed by the important side effect and the exclusion.

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 simple three-parameter tool, the description covers purpose, valid inputs, a key side effect, and what it does not do. It does not describe the response or prerequisites, but the tool is straightforward and the missing details are unlikely to block correct invocation.

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?

The description adds semantic value for the outcome parameter by listing the only valid values. However, session_id and observation_id are left entirely to their schema titles, and the meanings of the outcome values themselves are not explained. With 0% schema coverage, this is partial compensation only.

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 uses a specific verb ('Acknowledge') and resource ('client review') and enumerates the four outcomes, so it's clear what the tool does. It also clarifies that this is not a send receipt, which helps separate it from preview/reply actions, though it does not explicitly contrast any sibling tool by name.

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 gives clear context for when to use the tool: acknowledging client review with one of four outcomes. The warning that 'uncertain pauses the session' and that it 'never [is] a send receipt' provide some when-not guidance, but no sibling alternative is explicitly named.

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