get_lords_journal_index_items

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

No annotations are provided, so the description carries the full behavioral burden; it does disclose that the call returns the index item plus its references, which is useful. However, it says nothing about permissions, whether a missing item errors or returns empty, or any pagination/rate limits, which are meaningful gaps for a no-annotation tool.

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?

Purpose and the sibling pointer are front-loaded, which is good, but the opening pipe-separated keyword fragment is filler and the Returns line duplicates what the output schema already declares.

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?

An output schema exists, so the return-values sentence is redundant rather than compensating. For a simple two-required-param getter with no annotations, the description is minimally adequate but omits error behavior and how the required identifiers relate to other Lords Journal tools.

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 Args block is the only documentation, and it merely restates the field names ("GUID of the Journal index item", "Journal volume id the item belongs to"). It adds no guidance on where to obtain these values (e.g., from general-index results or get_lords_journal_volumes) or what format the GUID takes beyond the type.

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 Lords Journal index item") and clarifies the scope as expanding a single entry found in a general index, which distinguishes it from the general-index retrieval tool. The pipe-separated fragment "Journal index entry, references, sub-items" is noisy and not a clean differentiation, keeping it below a 5.

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?

"Use to expand one index item found in a general index" gives an explicit trigger condition, and "See also: get_lords_journal_general_index" names the upstream alternative. It stops short of stating when NOT to use it or what a caller should do if the GUID is unknown.

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