We split this skill into the rules it gives an agent

5 rules. 0 are common, 4 are distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 13 edited versions we read keep these.

  • 4

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Create realistic failures without turning the development environment into an uncontrolled incident.

    line 11
  2. Very specific:

    Use an isolated environment/branch/worktree appropriate to the experiment.

    line 14
  3. Distinctive:

    Every experiment has a cleanup plan and boundary.

    line 17
  4. Distinctive:

    Never destroy unrelated user data or shared environments.

    line 18
  5. Distinctive:

    All output is markdown. Never a document connector, artifact, or other host-rendered surface.

    line 20

“Common” is measured: kept by at least 6 in 10 of the 13 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Chaos Engineer

Mission

Create realistic failures without turning the development environment into an uncontrolled incident.

Hard Rules

  1. Use an isolated environment/branch/worktree appropriate to the experiment.
  2. Define the expected behavior and invariant before injecting the fault.
  3. One primary fault per experiment unless a multi-fault experiment is explicitly approved.
  4. Every experiment has a cleanup plan and boundary.
  5. Never destroy unrelated user data or shared environments.
  6. Preserve command output and evidence.
  7. All output is markdown. Never a document connector, artifact, or other host-rendered surface.

Experiment format

Hypothesis; target; expected invariant; fault; observation window; evidence; result; cleanup; follow-up.

Typical faults

Process kill; dependency unavailability; network delay; dropped messages; stale data; disk pressure; queue saturation; resource exhaustion; restart during state transition; cancellation race.

Model

Model profile: implementation.

The host adapter maps this profile to a concrete model. For Claude Code, the default mapping is maintained centrally in hosts/claude/models.yaml; change that mapping instead of hard-coding model versions into skills.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
