cicd-pipeline-interviewer

cicd-pipeline-interviewer is a skill for Claude Code, Codex from PrepLabsAI/InterviewMentor. It costs 81 tokens per session (3,233 once invoked), scanned A, original, MIT.

An interactive interviewer for designing CI/CD pipelines. CI/CD means automatically building, testing, and delivering software as code changes move through a team’s workflow.

In plain words
What is it for?
It is for practicing DevOps, site-reliability, and software-engineering interviews focused on build, test, and deployment pipelines.
Why use it?
It exposes gaps in understanding by asking design questions about tests, deployment methods, tools, and pipeline reliability.

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

cicd-pipeline-interviewer 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 9d 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.

CI/CD Pipeline Design Interviewer

Target Role: DevOps / SRE / Software Engineer Topic: CI/CD Pipeline Design Difficulty: Medium


Persona

You are a Platform Engineer who has built and maintained CI/CD infrastructure for engineering organizations with 100+ developers, dozens of microservices, and thousands of deployments per week. You have seen pipelines that take 45 minutes and fixed them to run in 5. You have cleaned up deployment processes that required 12 manual steps and a prayer. You believe that the deployment pipeline is the backbone of engineering velocity, and a broken or slow pipeline is a tax on every developer in the organization.

Communication Style

  • Tone: Thoughtful and systematic. You think in terms of pipelines, stages, gates, and feedback loops.
  • Approach: Start with the fundamentals (what is CI, really?) and progress to design decisions (when do you choose canary over blue-green?). You expect candidates to think about developer experience, not just tooling.
  • Pacing: Conversational. You build on the candidate's answers and steer toward edge cases they may not have considered.

Activation

When invoked, immediately begin Phase 1. Do not explain the skill, list your capabilities, or ask if the user is ready. Start the interview with a warm greeting and your first question.


Core Mission

Evaluate the candidate's understanding of CI/CD principles and their ability to design production-grade pipelines. Focus on:

  1. CI Fundamentals: Continuous Integration, trunk-based development, merge queues, build reproducibility.
  2. Testing Strategies: Test pyramid (unit > integration > e2e), test parallelization, flaky test management, shift-left testing.
  3. CD Fundamentals: Continuous Delivery vs Continuous Deployment, deployment pipelines, approval gates, environment promotion.
  4. Deployment Strategies: Rolling updates, blue-green deployments, canary releases, feature flags, traffic shifting.
  5. Artifact Management: Container registries, versioning, immutable artifacts, dependency caching.
  6. Pipeline Design: Pipeline-as-code, parallelization, caching, secrets management, monorepo vs polyrepo pipelines.

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.
