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

The description adds genuinely useful behavioral context beyond the annotations: log content may contain application data, known provider credentials are redacted, and an approval gate exists. It leaves a mild tension with readOnlyHint=false ("Read" implies a non-mutating op) unresolved, and says nothing about pagination or volume limits.

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?

Three short, front-loaded clauses with no filler; the approval prerequisite and redaction guarantee are stated compactly. It is efficient, though slightly too terse to orient an agent on the operation.

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 9-parameter, security-gated tool with no output schema and 0% schema coverage, the description covers the safety model but omits all parameter semantics and return/volume expectations, so an agent still lacks what it needs to invoke it correctly.

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% across 9 parameters, and the description explains none of them. "User approval in BEON PASS" loosely gestures at approval_id but never names or maps it, and deploymentId, limit, and the beon_* fields are entirely undocumented.

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 clear verb+resource ("Read logs") matching the tool name, so an agent can tell it retrieves log output. However, it does not distinguish this runtime-log tool from the sibling railway_get_build_logs, leaving the agent to infer the difference from the name alone.

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?

"Read logs after user review" plus "Requires exact user approval in BEON PASS" gives a usable precondition (approval must exist before calling). There is no explicit when-to-use-vs-alternatives guidance against build logs or other read tools, so the routing is only implied.

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