channel_get_grid_bit

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

With no annotations, the description carries the burden of behavioral disclosure. It clearly states read-only behavior and adds 0-based positioning. However, it omits the return value format and what happens on invalid positions, and it never explains the role of 'index'.

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 focused sentence with no filler. The key action is front-loaded, and the scoping detail is compactly placed.

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, so the description should at least indicate what the tool returns, but it does not. It also leaves 'index' unexplained and does not mention whether the bit is a boolean on/off value or how out-of-range positions behave.

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 compensate. It clarifies 'position' as a 0-based step, but 'index' is left entirely undefined. With one of two required parameters unaddressed, parameter semantics are incomplete.

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 states a specific verb and resource: 'Read a single step-sequencer bit.' The parenthetical clarifies the step position, and the read action contrasts with the sibling set_grid_bit. However, it does not fully distinguish from get_step_sequence or clarify what 'index' refers to.

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 word 'Read' implies this is for reading rather than writing, and 'single bit' implies it is not for reading sequences. But there is no explicit when-to-use vs alternatives guidance, and no exclusions or conditions are mentioned.

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