coding-interview-agent

coding-interview-agent is a plugin for Claude Code from PrepLabsAI/InterviewMentor. Its manifest loads nothing; the 44 skills it bundles cost 3,088 tokens per session together, scanned A, original, MIT.

A set of AI-led mock interviews for software engineering roles. It covers coding problems, system design, data, DevOps, machine learning, debugging, product management, and behavioral questions.

In plain words
What is it for?
Use it to practise algorithms, system design, SQL, incident response, cloud operations, ML engineering, and behavioral interviews.
Why use it?
It gives interview practice without needing another person to act as the interviewer. Progressive hints and evaluation rubrics help show where your answers need work.

Security

Grade A, and why

coding-interview-agent 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.

What it installs

The manifest is a name and a version. 44 skills travel with it, and installing the plugin installs all of them — 3,088 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#coding-interview-agent in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
