data-sharing-and-publishing-contracts

data-sharing-and-publishing-contracts is a skill for Claude Code, Codex from vaquarkhan/data-engineering-agent-skills. It costs 49 tokens per session (443 once invoked), scanned A, original, MIT.

A guide for publishing tables, files, extracts, APIs, or reverse ETL outputs as dependable data products. Reverse ETL means sending prepared warehouse data into operational tools or systems.

In plain words
What is it for?
Use it to define a dataset's schema, grain, audience, delivery method, freshness, retention, privacy limits, service expectations, versioning, and deprecation policy.
Why use it?
It prevents downstream users and systems from relying on undocumented assumptions about a dataset. Clear ownership, compatibility rules, access limits, and change notices reduce surprises when published data changes.

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-sharing-and-publishing-contracts 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 10d 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.

What it actually says

Data Sharing And Publishing Contracts

Overview

Use this skill when data leaves the producing team and becomes a product for other teams, systems, or partners. It helps agents define stable publish contracts with ownership, compatibility, and operational expectations.

When to Use

  • publishing curated tables or marts
  • sharing extracts or files with other teams or partners
  • exposing governed data through APIs or reverse ETL
  • modifying an existing consumer-facing dataset

Do not publish widely-used data with implicit contracts.

Workflow

  1. Define the published contract. Include:

    • owner
    • audience
    • schema
    • grain
    • delivery method
    • freshness and retention expectations
  2. Identify compatibility and versioning needs.

  3. Define access and usage boundaries. Capture:

    • allowed consumers
    • privacy constraints
    • SLA expectations
    • communication path for changes
  4. Validate publish readiness before release.

  5. Document change policy. Consumers should know what can change, how they will be notified, and how long deprecated behavior lasts.

Common Rationalizations

Rationalization Reality
"It is just one extract for another team." One-off exports often become critical dependencies.
"Consumers can ask if something changes." Many consumers only discover changes after failure.
"The schema tells them everything they need." Delivery timing, freshness, retention, and ownership matter too.

Red Flags

  • published outputs have no owner
  • delivery or freshness expectations are missing
  • breaking changes are shipped without versioning or notice
  • access boundaries are unclear for shared datasets

Verification

  • The publish contract covers audience, schema, delivery, and freshness
  • Ownership and communication path are defined
  • Compatibility and access expectations are explicit
  • Release readiness is validated before consumers depend on it
Changes

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.
