vibe-build

vibe-build is a skill for Claude Code from KhazP/vibe-coding-prompt-template. It costs 18 tokens per session (260 once invoked), scanned A, original, MIT.

A guided implementation process for building a minimum viable product, or MVP, from an existing project plan. It works through features incrementally and tests each one.

In plain words
What is it for?
Use it to start coding an MVP, follow an AGENTS.md plan, implement features, run tests, and continue work across sessions.
Why use it?
It gives coding work a defined source of truth and checks progress as features are added. It also identifies the planning documents needed before implementation.

About the project

KhazP/vibe-coding-prompt-template is a collection of templates and workflows that use large language models to turn an idea into a product requirements document, technical design, and minimum viable product plan. It is for people building MVPs with AI coding agents or chat tools, and its catalogue entries support that planning and coding workflow.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

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-build 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 1mo 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 actually says

Build a new-project slice

Establish the requested outcome and acceptance criteria from the user's brief and relevant project decisions. Read applicable repository instructions and only the documents needed for this slice. An absent or stale MEMORY.md does not require rebuilding the whole planning workflow.

Implement the intended behavior using the chosen stack. Preserve unrelated work and make a recovery checkpoint when the change warrants it. Add accounts, databases, infrastructure, paid services, and AI only when requirements justify them. Continue until the requested slice works, not merely until files exist.

Use the project's affected checks and exercise the relevant user journey when runtime access permits it. Fix failures caused by the change, distinguish pre-existing failures, and reuse results that remain valid. A setup validator or passing build alone is not evidence of interactive behavior.

Update project progress when the repository maintains it. Report the outcome, actual checks, unverified behavior, and any concrete blocker or recovery note. External sends, production changes, store submission, and deployment remain subject to authorization for their specific effect and target.

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.
