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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered structurally. The description adds only the HTTP route (GET /api/v2/log/transaction/{id}), which is redundant REST metadata rather than behavioral context such as not-found handling or auth requirements.

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?

Two short sentences, front-loaded with the purpose and with no filler. The trailing HTTP route is information the agent cannot act on, which is the only waste.

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 one-parameter read tool with full schema coverage and annotations carrying the safety profile, this is minimally adequate. With no output schema, a brief note on what the returned transaction log contains would have closed the remaining gap.

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 100% and the single 'id' parameter is already documented as 'Transaction log id' in the schema. The description restates the same fact ('by id') without adding format, source, or lookup guidance, so the baseline of 3 applies.

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?

States a specific verb and resource: 'Get a transaction log by id', which is distinct from the sibling list endpoint get_log_transaction and from get_log_transaction_bot_signal_type_service_id. It does not explicitly name those alternatives, so sibling differentiation is left implicit.

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 only usage cue is 'by id', which just restates the single required parameter. There is no guidance on when to use this versus the paginated get_log_transaction listing or the filtered get_log_transaction_bot_signal_type_service_id variant.

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