generating-dataflow-pipeline

generating-dataflow-pipeline is a skill for Claude Code, Codex from OpenDCAI/Dataflow-LoopAI. It costs 20 tokens per session (5,720 once invoked), scanned A, original, Apache-2.0.

A planner that selects operators and writes standard DataFlow pipeline code from a task description and a small JSONL sample. JSONL is a text format with one JSON object per line.

In plain words
What is it for?
Planning pipelines for document processing, text transformation, and multi-field composition; selecting supported operators; validating dependencies; and generating code tied to the supplied sample file.
Why use it?
It uses the sample to infer fields and data types, helping choose compatible processing steps and avoid broken field dependencies.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is Sample file: [Path to JSONL file, e.g., ./data/input.jsonl].

Good fit Planning pipelines for document processing, text transformation, and multi-field composition; selecting supported operators; validating dependencies; and generating code tied to the supplied sample file.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

generating-dataflow-pipeline 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (templates/pipeline_template.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

DataFlow Pipeline Code Generator

Goal

This skill is used when users provide:

  • Target: What the pipeline should achieve
  • Sample Data File: Path to a JSONL file containing 1-5 representative data samples

The skill must:

  1. Read and analyze the JSONL file at the provided path
  2. Infer data structure, field types, and content characteristics
  3. Determine task type based on file content (document processing, text transformation, multi-field composition)
  4. Select appropriate operators from preferred primitives
  5. Validate field dependencies
  6. Output intermediate operator decision summary
  7. Generate standard DataFlow pipeline code with first_entry_file_name set to the user-provided file path

User Input Format

Users provide:

Target: [Clear task description]
Sample file: [Path to JSONL file, e.g., ./data/input.jsonl]

Important: The sample file is a JSONL file (one JSON object per line), not a JSON array.

Preferred Operator Strategy

Six Core Primitives (high-coverage operators for most data science tasks):

  1. PromptedGenerator - Single-field LLM generation
  2. FormatStrPromptedGenerator - Multi-field template generation
  3. Text2MultiHopQAGenerator - Multi-hop QA pair construction
  4. PromptedFilter - LLM-based quality filtering
  5. GeneralFilter - Rule-based filtering
  6. KBC trio (always used together in order): FileOrURLToMarkdownConverterFlash → KBCChunkGenerator → KBCTextCleaner

These are preferred primitives, not fixed workflows. They can be used repeatedly and combined flexibly.

Operator Selection Priority Rule (MANDATORY)

When a specialized operator exists for the task, it MUST be used over generic operators. Do NOT use PromptedGenerator to replicate functionality that a dedicated operator already provides.

Decision table (check in order, use the first match):

Task / Scenario Required Operator Do NOT use
Generate QA pairs from text Text2MultiHopQAGenerator PromptedGenerator with QA prompt
Convert file path / URL to text KBC trio (FileOrURLToMarkdownConverterFlash → KBCChunkGenerator → KBCTextCleaner) PromptedGenerator to summarize files
Score / evaluate using multiple fields FormatStrPromptedGenerator + GeneralFilter PromptedFilter (single input_key only)
Filter by deterministic rule on existing fields GeneralFilter PromptedFilter
Generate new content from a single field PromptedGenerator —
Generate new content from multiple fields FormatStrPromptedGenerator Multiple PromptedGenerator steps

generating-dataflow-pipeline is a skill published in the GitHub repository OpenDCAI/Dataflow-LoopAI (29 stars, last pushed 16d ago), licensed Apache-2.0. It adds 20 tokens to every session and 5,720 once invoked, about $0.0001 per session on Opus 5.5. 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.
