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 wshobson/agents at 46891e7e60.

    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 postmortem-writing skill helps AI agents analyze past events or processes to identify what went well, what didn’t, and how future outcomes can be improved. It enables structured reflection on completed tasks, projects, or incidents, often used in professional settings like software development, project management, and incident response.

When to use it

  • After a project has been completed to evaluate its success and lessons learned
  • Following an incident or failure to identify root causes and prevent recurrence
  • As part of a team retrospective to improve collaboration and processes

Key capabilities

  • Structured analysis of past events
  • Identification of successes and failures
  • Generation of actionable insights for future improvement

Example prompts

  • "Write a postmortem report on the recent software deployment."
  • "Analyze what went wrong with the customer support incident last week."
  • "Summarize the key takeaways from our team’s project retrospective."

Tips & gotchas

  • Provide clear context or data about the event being analyzed for accurate results.
  • Use this skill in conjunction with other tools like incident tracking systems to ensure comprehensive insights.
