batch_fetch

Fetch up to 50 papers in one batch with bounded concurrency and input-ordered results for compact manifests or full Markdown output.

Instructions

Fetch 1..50 papers with bounded concurrency and input-ordered compact manifest/acceptance results. It may access remote services and write the same cache, artifacts, or Markdown as fetch_paper. detail=bounded returns only a batch-wide bounded text sample. batch_results atomically writes the final input-ordered JSONL result; overwrite defaults false. Browser routes automatically prepare/update managed Camoufox before browser launch.

A3.5/5.0

Behavior5/5

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

The description meaningfully supplements the annotations by disclosing remote service access, shared cache/artifact/Markdown side effects, the detail=bounded sampling behavior, atomic JSONL writing via batch_results, the overwrite default, and automatic Camoufox preparation for browser routes. This goes well beyond the annotations and is valuable behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense but mostly front-loaded: the core purpose appears first, followed by high-impact behavioral caveats. It is not overly long, though the jargon-heavy phrasing (input-ordered compact manifest/acceptance results, batch_results atomically writes) could be clearer for an AI agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a complex tool with 18 parameters, nested objects, no output schema, and non-trivial side effects. The description covers a few important behaviors but leaves many parameters and their interactions unexplained, making it incomplete for safe and correct invocation in varied scenarios.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

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, but it only explains detail, batch_results, overwrite, and browser-route preparation. Most of the 18 parameters, including strategy, modes, concurrency, no_download, artifact_mode, prefer_cache, and markdown settings, receive no semantic explanation. The partial coverage is insufficient for such a large schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool as a batch fetch operation for 1–50 papers and notes bounded concurrency plus input-ordered results. It references fetch_paper as a related sibling but does not explicitly contrast them; still, the batch scope is unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage context is implied by the batch range and the comparison to fetch_paper, but the description never states when to choose batch_fetch over batch_check, batch_resolve, or other siblings. It provides some operational context (remote access, cache writes, browser setup) but no explicit when/when-not guidance.

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