dataflow-diagram

dataflow-diagram is a skill for Codex from OutlineDriven/outline-driven-development. It costs 34 tokens per session (1,171 once invoked), scanned A, original, Apache-2.0.

A typed description and interactive HTML diagram of how data moves between sources, storage, transformations, and users or systems.

In plain words
What is it for?
Use it to map ETL or ELT pipelines, data custody, governance, transformations, stores, sources, and consumers.
Why use it?
It makes data lineage, ownership, and processing steps easier to inspect without guessing relationships.

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

dataflow-diagram 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.

Dataflow diagram

Contract

Field Bound contract
Trigger The user asks to visualize data movement, ETL or ELT, lineage, transformation stages, custody, governance, stores, sources, or consumers.
Authority Reversible local: writes only the named local artifacts below; rollback is deleting them. No remote mutation.
Side effect Writes a typed dataflow JSON specification and one self-contained interactive HTML artifact, with optional bounded visual-evidence sidecars.
Done The diagram represents the requested movement and custody facts without inferred causality, validates against both schemas, passes all render and atomic-delivery checks, and has a hash-bound receipt plus truthful visual-review status.

Inputs

The user must supply the data contracts and movement facts to depict: sources, stores, consumers, transformation stages, custody owners, and the flows between them. Optional inputs are governance labels, lineage annotations, and a request for visual-evidence sidecars. Do not infer a flow, stage, custody assignment, or causal relationship the user did not state; ask for the missing fact rather than inventing it.

Procedure

  1. Bound scope before mutation: confirm the requested movement and custody facts, and list the exact local files to write (the dataflow JSON specification and one self-contained interactive HTML artifact, plus any requested visual-evidence sidecars). Write nothing else. Done when: the file set is listed and confirmed before any mutation.
  2. Model the dataflow as stages, nodes, flows, and semantic kinds using only the user-supplied facts. Record each node's kind (source, store, transformation, consumer, governance checkpoint) and each flow's source, target, and custody owner as stated. Add no flow, stage, or causal edge the user did not provide. Done when: the model contains only user-supplied facts with no inferred edges.
  3. Serialize the model into the typed dataflow JSON specification. Validate it strictly against the dataflow schema and the common schema: every required field present, every semantic kind from the allowed set, every flow resolvable to declared nodes, and no extra or unknown fields accepted. Done when: the JSON specification validates strictly against both schemas.
  4. Render one self-contained interactive HTML artifact from the validated specification. The artifact must load with no external network or runtime dependency, render the stages and flows with their semantic kinds and custody owners, and let a reader traverse the movement interactively. Done when: the HTML artifact loads with no external dependency and renders all stages and flows interactively.
  5. Run the render check (the artifact renders the full requested movement and custody facts) and the atomic-delivery check (the JSON specification and the HTML artifact are each complete and usable on their own). If either fails, fix the artifact or specification and re-run; do not declare done on a partial pass. Done when: both the render and atomic-delivery checks pass.
  6. Capture a hash-bound receipt: record the SHA-256 of the delivered JSON specification and HTML artifact, and the schema versions validated against. Record a truthful visual-review status stating whether a human visually confirmed the rendered artifact, was not yet reviewed, or reviewed and found defects; never mark unreviewed output as confirmed. Done when: the receipt records both hashes, schema versions, and a truthful visual-review status.
  7. If visual-evidence sidecars were requested, produce only the bounded set asked for (for example, a screenshot or rendered snapshot of the artifact) and name them in the receipt. Do not generate unrequested sidecars. Done when: requested sidecars are produced and named in the receipt, or no sidecars are produced when none were requested.

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.

dataflow-diagram is a skill published in the GitHub repository OutlineDriven/outline-driven-development (52 stars, last pushed 3d ago), licensed Apache-2.0. It adds 34 tokens to every session and 1,171 once invoked, about $0.0002 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 2026-09-03.
