Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned astronomer/agents at cbe1141f54.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The tracing-upstream-lineage skill enables AI agents to trace and analyze the lineage of data or processes upstream in a system. It helps identify dependencies, origins, and transformations applied to data elements, making it easier to understand how information flows through complex systems.

When to use it

  • Investigating the source of data inconsistencies or errors in a pipeline.
  • Auditing data transformations for compliance or debugging purposes.
  • Mapping out dependencies between different components in a distributed system.
  • Understanding the root cause of an issue by following upstream processes.

Key capabilities

  • Tracing data lineage through multiple transformation steps.
  • Identifying upstream sources and dependencies.
  • Visualizing process flow to understand how data is manipulated or passed along.

Example prompts

  • "Trace the origin of this dataset back through all transformations."
  • "Show me the upstream processes that contributed to this result."
  • "What systems or data sources are involved in this pipeline?"

Tips & gotchas

  • Ensure that your system has proper metadata tracking enabled for accurate lineage tracing.
  • This skill may require access to logs, schemas, or process definitions to function effectively.
