chaos-dr-test

chaos-dr-test is a skill for Claude Code, Codex from harness/harness-skills. It costs 121 tokens per session (2,359 once invoked), scanned A, original, Apache-2.0.

A workflow for creating and editing Harness disaster-recovery test pipelines with chaos steps. Chaos testing deliberately introduces faults, probes, or actions to check how a system responds to failures; Harness is the pipeline platform used here.

In plain words
What is it for?
Use it to add or change ChaosFault, ChaosProbe, ChaosAction, and Chaos steps in Harness DRTest stages and pipelines.
Why use it?
It helps prevent false reports of successful changes by requiring confirmed tool results and the correct organization and project scope.

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

chaos-dr-test 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Chaos DR Test

Create and edit Harness DR Test pipelines — pipelines with a DRTest stage containing ChaosFault, ChaosProbe, ChaosAction, and Chaos steps — via MCP.

MANDATORY — Tool Result Verification:

  • NEVER claim a tool call succeeded without an explicit success response from the tool.
  • NEVER fabricate, assume, or pre-empt tool results. If you called a tool and did not receive a confirmed result, say so and retry.
  • When a tool returns a review/elicitation prompt (e.g., "Waiting for user to review before update..."), the user's approval does NOT mean the operation completed. You MUST wait for the follow-up tool response confirming execution before reporting success.
  • If the tool response is ambiguous or missing, tell the user honestly and offer to retry.

Scope Rules

Follow references/scope-establishment.md for establishing org/project scope before calling harness_list, harness_get, harness_create, harness_update, or harness_execute in this skill:

  • Parse org / project from the user's message or a pasted Harness UI URL first.
  • Ask only for what is missing — do not re-ask for values already known.
  • Restate the active scope before the first mutating call.
  • Never invent a default org/project. If either is missing, ask the user to select it before calling a project-scoped resource; do not fall back to account scope silently.

Instructions

YAML Output Conventions

Output style — always emit block-style YAML for pipeline manifests (each key on its own line, list items on their own line with -, children indented). The YAML examples shown in references/components.md (Series + Parallel Steps, Full DRTest Pipeline, Chaos step) appear as minified JSON purely for token efficiency — JSON parses identically to YAML, so the examples remain authoritative for field names and structure, but the pipeline YAML you produce MUST be block-style matching the canonical scaffold below. Never put JSON in the request body for harness_create or harness_update pipeline YAML.

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.
