DevOps Guidelines

Apply only sections relevant to workload/provider/environment/acceptance criteria. Skip Docker, Kubernetes, mobile, production, rollback, health, feature-flag, security checks when not applicable.

Deployment strategy

  • Rolling (default): gradual, zero-downtime replacement.
  • Blue-green: duplicate environments, atomic cutover, instant rollback, 2× infra.
  • Canary: route small % first; requires traffic splitting.

Docker

  • Pin base-image tags (node:22-alpine); NEVER :latest.
  • Multi-stage builds + non-root user. Copy deps first for caching.
  • .dockerignore: node_modules, .git, tests. Define HEALTHCHECK + resource limits.

Kubernetes

Configure startup, readiness, liveness probes with workload-appropriate initial delays/thresholds.

CI/CD

  • PR: lint -> typecheck -> unit -> integration -> preview.
  • Main: build -> staging -> smoke -> production.

Health and shutdown

  • Simple: GET /health -> { "status": "ok" }.
  • Detailed: dependencies, uptime, version.
  • Services MUST expose meaningful health + gracefully handle SIGTERM when workload requires it.

Configuration

Use environment variables (Twelve-Factor), separated by environment. Validate at startup + fail fast. NEVER commit secrets or hard-code NODE_ENV=production.

Rollback

  • Kubernetes: kubectl rollout undo.
  • Vercel: vercel rollback.
  • Docker: redeploy previous pinned image.

Feature Flags

  • Lifecycle: create -> enable -> 5% -> 25% -> 50% -> 100% -> remove flag + dead code.
  • Every flag MUST have owner, expiration, rollback trigger. Remove within two weeks.

Checklists

  • Pre-deploy: passing tests, code review, env vars, migrations, rollback plan.
  • Post-deploy: healthy, monitored, old pods terminated, outcome documented.
  • Production: passing tests; no hardcoded secrets; JSON logs; meaningful health; pinned versions; validated env vars; resource limits; TLS; CVE scan; CORS; rate limiting; CSP/HSTS/X-Frame-Options; tested rollback; runbook; on-call.
  • Apply security/CVE checks to executable or security-sensitive workloads.

Mobile Deployment

  • EAS: eas build:configure; eas build -p ios|android --profile preview; eas update --branch production; --auto-submit.
  • Fastlane: iOS match/cert/sigh/pilot; Android Gradle/supply.
  • Credentials in env/secret storage, never Git. Automate iOS signing with fastlane match; use keytool + Google Play App Signing for Android.
  • TestFlight: internal instant; external 90 days/100 testers. Google Play: internal/beta/production. Expect 1–7 days review.
  • Rollback: EAS eas update:rollback; native release -> revert build; store release -> reduce phased rollout.

概要と使いどころ

acquire-codebase-knowledge

無料

Use this skill when the user explicitly asks to map, document, or onboard into an existing codebase. Trigger for prompts like "map this codebase", "document this architecture", "onboard me to this repo", or "create codebase docs". Do not trigger for routine feature implementation, bug fixes, or narrow code edits unless the user asks for repository-level discovery.

acreadiness-assess

無料

Run the AgentRC readiness assessment on the current repository and produce a static HTML dashboard at reports/index.html. Wraps `npx github:microsoft/agentrc readiness` and hands off rendering to the @ai-readiness-reporter custom agent. Supports policies (--policy) for org-specific scoring. Use when asked to assess, audit, or score the AI readiness of a repo.

acreadiness-generate-instructions

無料

Generate tailored AI agent instruction files via AgentRC instructions command. Produces .github/copilot-instructions.md (default, recommended for Copilot in VS Code) plus optional per-area .instructions.md files with applyTo globs for monorepos. Use after running /acreadiness-assess to close gaps in the AI Tooling pillar.

acreadiness-policy

無料

Help the user pick, write, or apply an AgentRC policy. Policies customise readiness scoring by disabling irrelevant checks, overriding impact/level, setting pass-rate thresholds, or chaining org baselines with team overrides. Use when the user asks about strict mode, AI-only scoring, custom weights, CI gating, or wants org-wide standardisation.

ad-campaign-analyzer

無料

Use this skill when the user shares ad campaign performance data and asks what to cut, scale, or test. Trigger for prompts like "analyze my ad campaigns", "where am I wasting ad spend", "reallocate my ad budget", "which ads are actually working", or "ROAS analysis". Do not trigger for campaign planning or creative generation without performance data.
