channel_get_grid_bit

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

No annotations exist, so the description carries the burden. It correctly indicates a read operation (non-destructive) but does not detail error handling or constraints (e.g., valid parameter ranges). The behavioral picture is minimal but accurate.

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 sentence with no filler. The most critical information (verb, resource, position base) is front-loaded and concise.

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 simple read tool with 2 parameters and no output schema, the description covers purpose and clarifies position base. However, it fails to mention the return value type (e.g., boolean, integer) or valid input ranges, leaving gaps for an agent.

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 description adds value for 'position' (0-based step) but leaves 'index' unexplained. With 0% schema coverage, half of the parameters lack semantic guidance, making the description only partially helpful.

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 clearly states it 'Read[s] a single step-sequencer bit' and specifies the resource and that position is 0-based step within a pattern. This distinguishes from sibling tools like channel_set_grid_bit (write) and channel_get_step_sequence (get all steps).

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 implies read-only usage but does not explicitly state when to use this vs. alternatives like channel_get_step_sequence. No when-not-to-use guidance is provided.

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