approve_hitl

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action without revealing side effects, such as whether approval is irreversible, triggers notifications, or requires specific permissions. For a mutating operation, this lacks essential transparency about post-approval consequences.

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?

The description is an efficient single sentence that is front-loaded and free of extraneous words. However, it is so brief that it omits useful guidance, which could be included without sacrificing conciseness. It earns its place for purpose clarity but leaves room for more informative content.

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?

Given that this is a mutation tool with no annotations and no output schema, the description is incomplete. It only states the action and lacks context about the workflow, expected inputs' significance, or what happens after approval. For a tool that affects system state, more context is needed for safe and 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 input schema already provides descriptions for both parameters (escalation_id and comments) with 100% coverage, so the description adds no additional semantic value. The description itself does not mention parameters, but the schema handles the documentation adequately, meeting the baseline for high schema coverage.

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 'Approve a HITL escalation' clearly identifies the action (approve) and the resource (HITL escalation), making it distinct from sibling tools like reject_hitl, create_hitl, and list_hitls. It uses a specific verb+resource structure that leaves no ambiguity about the tool's core function.

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?

The description provides no guidance on when to use this tool versus alternatives such as reject_hitl, modify_hitl, or create_hitl. It does not mention any prerequisites, contextual triggers, or situations where approval is appropriate, leaving the agent to infer usage solely from the tool's name.

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