Pause Thinking

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the action ('pause') but doesn't explain what pausing entails—whether it's reversible, if it preserves state, or what happens to the thought chain. It also omits critical details like permissions needed, side effects, or error conditions. For a mutation tool with zero annotation coverage, this leaves significant behavioral gaps.

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 a single, efficient sentence with zero wasted words. It's front-loaded with the core action ('pause') and resource ('active thought process'), making it immediately scannable. Every word earns its place, and there's no redundancy or fluff.

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 the tool has an output schema (which handles return values) and 100% schema coverage for parameters, the description's minimalism is partially excusable. However, as a mutation tool with no annotations, it should still clarify behavioral aspects like reversibility or side effects. The description is adequate but leaves gaps in usage context and behavioral transparency.

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 100%, with both parameters (chainId, reason) clearly documented in the schema. The description adds no additional parameter semantics beyond implying the tool operates on a thought process (linked to chainId). Since the schema does the heavy lifting, the baseline score of 3 is appropriate—the description doesn't enhance or contradict parameter understanding.

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 'Pause an active thought process' clearly states the verb ('pause') and resource ('active thought process'), making the purpose immediately understandable. It distinguishes from siblings like 'resumeThinking' and 'completeThoughtProcess' by specifying the pause action rather than continuation or termination. However, it doesn't explicitly mention the chainId parameter's role in identifying which process to pause.

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 like 'resumeThinking' or 'completeThoughtProcess'. There's no mention of prerequisites (e.g., only works on active chains), nor does it specify what constitutes an 'active thought process' that can be paused. The agent must infer usage from the tool name alone.

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