parse_references

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

With no annotations, the description carries the full behavioral burden and does so well: it declares read-only status, heuristic parsing, per-entry parse_confidence (full/partial/failed), verbatim retention of failed entries ('will never be converted'), detection of Word-native vs third-party citation fields, and refusal behavior around text conversion. This goes well beyond a basic summary.

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 front-loaded with the core purpose and then layers in essential behavioral detail. Every clause earns its place: confidence levels, failed-entry handling, citation positions, field detection, and style_hint usage are all informative without being padded.

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 analysis tool, this description is complete: it explains what is parsed, what metadata is produced, how failures are handled, how style_hint affects behavior, and the no-mutation guarantee. The presence of an output schema means detailed return structure does not need to be repeated in the description.

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. It does meaningfully explain style_hint with concrete examples ('apa7', 'ieee', 'turabian') and its effect on parsing. file_path is not explicitly described, but its role as the manuscript path is strongly implied by the first sentence; still, a one-sentence clarification would make parameter semantics complete.

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 names a specific verb ('Parse') and resource ('the manuscript's reference list ... and in-text citations') and states the output is 'a structured model.' It also positions itself as 'Read-only stage 1 of publication-style conversion,' which distinguishes it from the many conversion and citation-sibling tools by framing what it does and what it is a prerequisite for.

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 description gives clear context: this is the read-only first stage of publication-style conversion, and style_hint should be supplied when the source style is known to tighten parsing. It does not explicitly name sibling alternatives or state when-not-to-use it, so it stops short of a full 5, but an agent can infer the intended workflow.

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