list_cics_transactions

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds that results come from CMCI and can be capped, but says nothing about pagination, truncation warnings, or the shape of a transaction entry.

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?

A single well-formed sentence with the core action front-loaded and zero filler. It is efficient, though it stops short of any routing or constraint information that would make it exemplary.

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 read-only filtered list with full schema descriptions, complete annotation coverage and no output schema, the description supplies the essential mechanism (CMCI) and filter/cap behavior. Nothing critical is missing for correct invocation.

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 coverage is 100%, with each of the 6 parameters documented including examples and env-var fallback. The description only gestures at 'prefix/status filters and result capping', which maps to tranPrefix, status and maxResults but adds no syntax or behavior beyond the schema, so the baseline 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 ('List CICS transaction definitions') plus the retrieval mechanism and scope ('installed in a region via CMCI'). It is clearly distinguishable from siblings like get_cics_region_status or cics_disable_transaction, though it never names an alternative explicitly.

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 mention of 'prefix/status filters and result capping' implies when the filters are useful, but there is no explicit when-to-use guidance, no exclusions, and no reference to sibling tools such as list_cics_regions or get_cics_region_stats.

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