lakefs-versioning

lakefs-versioning is a skill for Claude Code from oyi77/1ai-skills. It costs 38 tokens per session (1,539 once invoked), scanned A, original, MIT.

A version-control system for data lakes, which are large stores of raw data. LakeFS provides Git-like branches, commits, merges, rollbacks, and access to earlier data states.

In plain words
What is it for?
Use it to experiment with datasets, roll back failed updates, merge approved changes, enforce checks in data pipelines, and maintain separate data views for tenants or teams.
Why use it?
It lets teams test data changes separately and recover when an update causes problems. Atomic commits and isolated branches make data pipelines easier to reproduce and review.

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

lakefs-versioning 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 12d 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.

Overview

LakeFS brings Git-like version control to data lakes. It enables branching, committing, merging, and reverting data changes — supporting atomic operations, isolated experimentation, and CI/CD for data.

Capabilities

  • Create branches for isolated data experiments
  • Commit atomic changes to data
  • Merge branches with conflict detection
  • Time travel to any previous data state
  • Run pre-commit and pre-merge hooks (CI/CD)
  • Works with S3, Azure Blob, GCS as storage backends
  • Compatible with Spark, Presto, Trino, Hive, dbt

When to Use

Trigger phrases:

  • "lakefs versioning"

  • "LakeFS data versioning — Git-like branching for data lakes, atomic commits, time"

  • Needing reproducible data pipelines

  • Experimenting with data changes without risk

  • Implementing CI/CD for data quality

  • Rolling back failed data updates

  • Supporting multi-tenant data isolation

When NOT to Use

  • Task is about data processing, not versioning
  • You need real-time data streaming (use streaming tools)
  • Task is about data storage, not version control
  • You don't have data pipeline infrastructure
  • Task is about database migrations (use migration tools)
  • You need data warehousing, not versioning

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.
