vibe-coding

vibe-coding is a skill for Claude Code, Codex from liqiongyu/lenny_skills_plus. It costs 19 tokens per session (2,014 once invoked), scanned A, original, Apache-2.0.

A guided method for turning a rough idea into a working prototype with AI-assisted coding. It focuses on a demo you can run, test, and adjust rather than a production system.

In plain words
What is it for?
Use it to define a prototype, break the work into tasks, prepare prompts, and iterate from generated code to a demo-ready result.
Why use it?
It gives structure to fast experimentation, so an idea does not remain a vague concept or become a large, risky build. It also encourages small changes, validation, and rollback.

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

vibe-coding 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.

Vibe Coding

Scope

Covers

  • Timeboxed, AI-assisted rapid prototyping ("vibe coding") to produce a functional demo (not slides)
  • Turning a rough idea into a buildable prototype spec + task board + prompt pack
  • A tight iteration loop: generate → run → verify → adjust → log decisions
  • "Build tools to build the thing" when it meaningfully speeds up the demo (timeboxed)
  • Safe use of coding agents: least privilege, no secrets, small diffs, validation, rollback

When to use

  • "Vibe code a working prototype we can demo in 30–90 minutes."
  • "Replace this Figma concept with a clickable prototype."
  • "I’m not an engineer—help me build a small app/tool with AI and ship a demo."
  • "Turn this AI feature idea into a proof-of-concept with a clear build loop and demo script."

When NOT to use

  • You need a production-grade system, hardening, scaling, or security review (use building-with-llms + engineering process).
  • You need upstream problem framing, strategy, or PRD-level alignment (use problem-definition, writing-prds).
  • The work is high-stakes/irreversible (payments, auth, medical, legal, safety-critical) without human owners and reviews.
  • The request is "build anything" with no demo target; do intake first and narrow to one scenario.
  • You want to evaluate whether to adopt a new AI tool or framework (use evaluating-new-technology).
  • You need an AI/LLM product strategy, not a prototype (use ai-product-strategy).
  • You're validating a startup idea at the business-model level, not building a demo (use startup-ideation).

Inputs

Minimum required

  • Prototype goal: what should a user be able to do in the demo (1–3 "happy path" tasks)
  • Target user + context (who uses it, where it fits)
  • Timebox (e.g., 30/60/90 minutes) + demo audience (internal, customer, exec)
  • Platform preference (web app, mobile, CLI, spreadsheet, etc.) and constraints (privacy, data sensitivity)
  • Data/integrations: mock data ok? any APIs needed? (default to mock)

Missing-info strategy

  • Ask up to 5 questions from references/INTAKE.md (3–5 at a time).
  • If details remain missing, proceed with explicit assumptions and offer 2–3 options (e.g., mock vs real data; simple UI vs polished).
  • If asked to run commands or write/modify files, request confirmation, keep changes in a dedicated folder, and include rollback guidance.

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.

vibe-coding is a skill published in the GitHub repository liqiongyu/lenny_skills_plus (52 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 19 tokens to every session and 2,014 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
