env_get_allowlist

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

No annotations are provided, so the description carries the full burden. "Get" implies a read, but it never states that the call is side-effect free, what happens if no allowlist is configured (empty vs default), or whether the allowlist is workspace- or environment-scoped.

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 short sentence with no filler and the key concept front-loaded. It is efficient, though its brevity is partly under-specification rather than tight writing.

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?

There is no output schema and no annotations, yet the description says nothing about the shape of the returned configuration (list of URLs? wildcard patterns? enabled flag?) or how it relates to env_set_allowlist. For a zero-param getter this is the main missing piece an agent needs.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The description correctly implies no inputs are needed.

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?

"Get the current URL allowlist configuration" names a specific verb and resource, and the resource (allowlist) is distinctive enough to separate it from the other env_* siblings. It does not explicitly name its write counterpart env_set_allowlist, but the read/write split is still inferable.

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?

No guidance on when to call this versus env_set_allowlist or env_list, and no mention of scope (global vs per-environment) or preconditions. The agent must infer that this is the read side of the allowlist pair purely from the name.

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