dsh-tool-chaos

Configuration

Installed defaults cannot inject a fault:

- id: tool-chaos
  config:
    enabled: false
    dryRun: true
    seed: dsh-tool-chaos
    allowGlobalWildcard: false
    rules: []

A bounded preview rule looks like this:

- id: tool-chaos
  config:
    enabled: true
    dryRun: true
    seed: retry-suite-v1
    allowGlobalWildcard: false
    rules:
      - id: first-github-error
        tool: github_*
        action: error
        scope: root
        argumentsPattern: ''
        probability: 1
        afterMatches: 0
        every: 1
        maxInjections: 1
        delayMs: 1000
        message: deterministic GitHub transport failure

tool is an anchored, case-sensitive glob. argumentsPattern runs against stable key-sorted JSON. DSH patch rows replace a row's complete config, so every overlay must restate all keys it relies on.
