What its author says it does

Copied from the file, not written here

Design canary rollout strategy with progressive traffic steps, guardrail metrics, and automated stop/rollback decisions. Use when releases need incremental risk containment and evidence-based promotion gates; do not use for full-environment cutover planning where blue-green is required.

Deployment Strategy Canary

Overview

Use this skill to release changes gradually while measuring real-user impact before broad rollout.

Scope Boundaries

  • Use this skill when the task matches the trigger condition described in description.
  • Do not use this skill when the primary task falls outside this skill's domain.

Shared References

  • Promotion and stop decision rules:
    • references/canary-promotion-rules.md

Templates And Assets

  • Rollout plan template:
    • assets/canary-rollout-plan-template.md
  • Guardrail matrix template:
    • assets/canary-guardrail-matrix-template.csv

Inputs To Gather

  • Critical SLOs and business guardrail metrics.
  • Traffic segmentation options (region, tenant, cohort).
  • Maximum acceptable degradation and rollback thresholds.
  • Release window and incident response readiness.

Deliverables

  • Canary progression plan (percentage/time/gates).
  • Guardrail matrix and promotion rules.
  • Automatic stop/rollback policy.
  • Post-promotion verification and observation window plan.

Quick Progression Example

  • Steps: 1% -> 5% -> 20% -> 50% -> 100%.
  • Hold at each step for fixed minimum time and metric stability checks.
  • Auto-rollback if error rate rises > threshold or SLO drops below floor.

Quality Standard

  • Promotion gates are objective and pre-registered.
  • Guardrails include technical and business impact signals.
  • Rollback automation/authority is clearly defined.
  • Segment choice avoids exposing highest-risk cohorts first.

Workflow

  1. Define canary audience and progression steps in assets/canary-rollout-plan-template.md.
  2. Set promotion and rollback criteria for each step using assets/canary-guardrail-matrix-template.csv.
  3. Deploy canary and monitor guardrails in real time.
  4. Promote only when criteria pass under references/canary-promotion-rules.md; otherwise stop/rollback.
  5. Complete rollout and run post-release verification.

Failure Conditions

  • Stop when promotion criteria are ambiguous or non-measurable.
  • Stop when telemetry cannot detect regressions quickly.
  • Escalate when rollback path is manual-only for high-criticality services.
