websex_browser_set_state

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

No annotations are provided, so the description carries the full disclosure burden and does not meet it. It does not state whether existing cookies/storage are overwritten or merged, whether the session must already exist, what auth or permissions are required, or whether the change is reversible.

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 no padding, which is efficient. It is arguably too terse for a five-parameter mutation tool, but the sentence itself earns its place.

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?

With no annotations, no output-schema explanation needed (an output schema exists), and 0% parameter documentation, the single sentence is insufficient for a state-mutating tool. It omits prerequisites, overwrite semantics, and any failure behavior an agent would need.

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 0%, so the description must compensate. It names three of the five parameters semantically (cookies, localStorage, sessionStorage), which is useful, but leaves engagement_id and session_id completely undocumented in both the description and 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 states a specific verb (Set) and resources (cookies, localStorage, sessionStorage) in a live browser session, so the operation is unambiguous. It does not explicitly contrast itself with the sibling websex_browser_state (which presumably reads state), relying on the reader to infer the set-vs-read distinction.

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?

There is no guidance on when to use this tool versus alternatives, no mention of prerequisites (e.g. an existing live browser session does not obviously need to be created first), and no exclusions. The only implicit usage cue is the word 'live browser session'.

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