get_field_orientation

Retrieves and ranks foundational papers for a research topic by citation impact and relevance. Bootstraps literature surveys with candidate papers for fast field orientation.

Instructions

Returns CANDIDATE FOUNDATIONAL PAPERS for a research topic — cheap retrieval only, no synthesis. Ranks papers by a blend of citation count (0.6 weight, captures importance) and semantic similarity to your topic (0.4 weight). Use this to bootstrap a literature survey or get a fast sense of the landscape. For a synthesized orientation report (key concepts, open problems, reading order), use the /field-guide skill which calls this tool internally. Does not require a Pro API key — no LLM calls are made.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
topicYesResearch area to orient on. Be specific for better results. Examples: 'diffusion models for protein structure prediction', 'efficient attention mechanisms for long-context LLMs', 'graph neural networks for molecular property prediction'.
limitNoNumber of candidate papers to return (5–30, default 15).
Behavior4/5

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

No annotations provided, so description carries full burden. Discloses cheap retrieval, no LLM calls, no Pro key, and ranking weights. Could mention coverage or recency limitations but still good transparency for a simple tool.

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

Conciseness5/5

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

Concise, well-structured, and front-loaded. Every sentence adds value: purpose, ranking, usage guidance, and API key note. No wasted words.

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

Completeness4/5

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

Provides sufficient context for a 2-parameter tool with no output schema. Explains input requirements and ranking. Lacks description of output format (e.g., what fields are returned), but overall complete for its scope.

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

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with good descriptions. The description adds value by explaining the ranking weights, and provides specific examples for the 'topic' parameter. Adds context beyond 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?

Clearly states the tool returns foundational papers for a research topic, explains ranking mechanism, and distinguishes from the /field-guide skill. However, does not explicitly differentiate from the sibling tool 'get_foundational_lineage'.

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

Usage Guidelines5/5

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

Explicitly states when to use (bootstrap literature survey, fast landscape sense) and when not to use (synthesized report requires field-guide skill). Also notes no Pro API key needed, providing clear guidance.

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