read_log

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

No annotations exist, so the description carries the full burden. It discloses that reads are bounded and that offset is byte-based, which is useful context. However, it does not mention error behavior, response format, rate limits, or what 'bounded' means in size.

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 terse sentence with no filler. Every word contributes, and it front-loads the core action and key scoping detail.

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?

With four parameters, no annotations, and no output schema, the description is far too sparse. It does not explain the run_id parameter, the meaning of limit, pagination beyond byte offsets, or what the caller should expect in the result.

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 for all parameters. It only clarifies the semantics of 'offset' (bytes), leaving run_id, limit, and stage_index unexplained in both schema and description. That is weak compensation for a four-parameter tool.

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 ('read') and resource ('log increments'), and the byte-offset detail helps characterize the operation. It is clearly distinct from sibling tools about experiments and artifacts, though 'increments' is slightly vague and the description does not mention the run_id context.

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?

There is no explicit guidance on when to use this tool versus alternatives. The intended use is implied by the name and description, and the siblings are unrelated, so confusion is unlikely, but no exclusions or alternative routing are provided.

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