data_analyst

Development rules for a data-analysis agent, software that examines collected data and explains findings with charts, dashboards, and screenshots.

In plain words
What is it for?
Use them when adding or changing tools in data_analyst_agent/, including tools that fetch data, create visual outputs, or support Agency Swarm workflows.
Why use it?
They provide a consistent way to inspect inputs, build data-gathering and visualization tools, and keep credentials out of runtime requests.

Cursor rule for Cursor

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 10 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 594 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

data_analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scope

  • These rules describe how to build and refine data_analyst_agent.
  • Keep edits limited to data_analyst_agent/ unless cross-agent collaboration is required.
  • Use this file to align tooling updates, visualization workflows, and testing practices with Agency Swarm conventions.

Data Analyst Agent Purpose

  • Analyze raw or collected data and clearly explain the findings.
  • Generate charts, dashboards, and screenshots that highlight trends and support decision-making.
  • Visualize the results and analyze them to reveal hidden trends.

Design Workflow

  1. Review existing analytics and browser utilities under tools/ and tools/utils/.
  2. Determine the format of the input data. If it's an online dashboard service - research api or methods of gathering data from it.
  3. Construct tools one by one inside the tools/ folder that allow the agent to fetch data and visualize it. Use either @function_tool or BaseTool.
  4. Source credentials via dotenv; never demand API keys or secrets as runtime inputs.
  5. Ensure each tool returns image outputs as described in the OpenAI Agents documentation: https://openai.github.io/openai-agents-python/tools/#returning-images-or-files-from-function-tools.
  6. Test each tool individually before proceeding with agent development.
  7. After tools are ready, create the Data Analyst agent. Begin with instructions.md, outlining the role, goals, available tools, and usage guidelines.

Customization Guidelines

Depending on needs, you may adjust:

  1. Data connectors - swap or extend integrations (databases, APIs, files) while preserving consistent return schemas.
  2. Visualization styles - introduce helper utilities for specialized chart types or interactive dashboards.
  3. Instruction emphasis - refine prompts to prioritize exploratory analysis, anomaly detection, or KPI reporting.

Customization Examples

  1. Introducing a warehouse connector (e.g., Snowflake) -> a tool that authenticates via env vars and returns tidy tables for plotting.
  2. Supporting CSV uploads -> requires a parser tool that validates headers, infers types and plots the data.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

data_analyst is a cursor rule published in the GitHub repository VRSEN/OpenSwarm (2,856 stars, last pushed 1mo ago), licensed MIT. It adds 10 tokens to every session and 594 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
