channel_set_step_sequence

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

With no annotations, the description must fully disclose behavior. It states the tool overwrites the step sequence and that steps must be a list of 0/1 ints up to pattern length, but it does not explain what happens if the pattern is null or if steps exceed the pattern length, nor does it mention permissions or side effects.

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 sentence, very concise with no wasted words. However, it could be restructured to front-load the action and then detail parameters, but current structure is acceptable.

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 tool with 3 parameters, no annotations, and no output schema, the description is inadequate. It fails to explain the index and pattern parameters, does not indicate the return value or effect on the channel, and lacks context on when to use this vs related tools like channel_set_grid_bit.

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?

Only the 'steps' parameter is described (as a list of 0/1 ints up to pattern length). The 'index' and 'pattern' parameters are not mentioned in the description. Schema coverage is 0%, so the description adds some value but insufficiently compensates for the lack of parameter documentation.

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 uses the verb 'Overwrite' and the resource 'step sequence', clearly indicating it replaces the existing step sequence. This distinguishes it from siblings like channel_get_step_sequence (read) and channel_clear_step_sequence (clear).

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. It does not mention when to use channel_set_grid_bit or channel_clear_step_sequence instead, nor does it specify prerequisites or conditions.

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