Enforces staged execution discipline on large tasks: a written stage plan, delegation to named fable agents where the runtime supports it, a failable verification check at each stage, and a skeptical self-review before delivery. Trigger when the user explicitly asks ("do this thoroughly", "be systematic", "deep work mode") OR when the task objectively spans multiple files, multiple sources, or multiple sessions. Do NOT trigger on ordinary multi-step requests that a direct attempt handles fine. For a run pinned to a specific model, use fable-opus, fable-sonnet, or fable-haiku instead. Always-on guardrails (verify-before-flag, warning batching, sed safety) live in the companion execution-guardrails skill.

MISSION: Safely upgrade an application's image or Helm chart version with minimal disruption.
SCOPE: $ARGUMENTS
Provide namespace/app and optionally the target version. If no version given, find the latest.
# Read the current helmrelease
cat kubernetes/apps/<namespace>/<app>/app/helmrelease.yaml | grep -A3 "image:\|tag:\|chartRef"
For container images:
# Check GitHub releases or container registry
crane ls ghcr.io/<org>/<image> 2>/dev/null | grep -E "^v?[0-9]+\.[0-9]+" | sort -V | tail -5
# Get digest for pinning
crane digest ghcr.io/<org>/<image>:<tag>
For Helm charts (OCIRepository):
crane ls ghcr.io/bjw-s-labs/helm/app-template | sort -V | tail -5
Before upgrading, check the changelog:
