session_profile_delete

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

No annotations are provided, so the description carries the full behavioral burden for a destructive operation. It hints at two modes (metadata vs. entire directory) but says nothing about irreversibility, permissions, side effects, or whether running sessions are affected.

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 efficient sentence with no filler, front-loading the verb and resource. The trailing 'or entire profile directory' clause is terse to the point of ambiguity about the triggering condition.

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?

An output schema exists so return values need not be described. However, for a destructive tool with zero annotations and 0% parameter coverage, the definition omits critical context: irreversibility, what exactly gets removed, and the effect of delete_user_data_dir.

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 explain both parameters. It alludes to the metadata-vs-directory distinction that maps to delete_user_data_dir, but never names the parameter, states the default, or clarifies what toggling it actually does. The required 'profile' parameter is entirely unexplained.

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 (Delete) and resource (profile metadata / profile directory), and distinguishes two deletion scopes. It does not explicitly name or differentiate itself against siblings like session_profile_list or session_proxy_delete, but the core action is unambiguous.

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 prerequisites, and no warning about when deletion is appropriate or dangerous. The agent must infer all usage context 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.
