websex_http_session_create

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

No annotations are provided, so the description carries the behavioral burden. It adds useful context ('persistent', 'engagement-scoped', 'declared target scope'), but says nothing about authentication needs, whether sessions can be reused concurrently, or lifecycle/destruction behavior. Return values are covered by the output schema.

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 filler, leading with the verb and resource. Efficient, though it is terse for an 8-parameter tool.

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 tool with 8 undocumented parameters, no annotations, and no title, a one-sentence description is thin. The output schema covers return values, but when-to-use context and parameter meaning are left to inference.

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 coverage is 0% across 8 parameters, so the description must compensate. It maps loosely to scope_hosts, default_headers, verify_tls and follow_redirects, but omits name, base_url, engagement_id and include_subdomains, and references 'cookies' for which no parameter exists.

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+resource ('Create a persistent engagement-scoped HTTP workbench session') and enumerates the configurable dimensions (scope, headers, TLS, redirects). The 'create' verb clearly separates it from session_list/get/update siblings, though no sibling is named explicitly.

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 conveys that the session is persistent and engagement-scoped, but gives no guidance on when to create a session versus using websex_http_request, websex_http_repeater, or the browser tools directly. No prerequisites or exclusions are stated.

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