A set of contribution rules for the Vibe Coding Repository Standard, a project containing guidance, templates, validators, and documentation for AI-assisted coding repositories.

In plain words
What is it for?
Use it when planning edits, explaining technical terms, checking links and validators, documenting tests, or reviewing privacy, safety, and compatibility claims.
Why use it?
It helps contributors make focused, understandable changes while separating confirmed facts from guesses and recording enough evidence to support behavior changes.

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-repository-standard AGENTS.md 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.

VCRS Repository Instructions

Purpose

This repository publishes the Vibe Coding Repository Standard (VCRS), its Codex-first reference implementation, prompts, templates, validators, and public documentation.

Communication

  • Write in plain, direct, user-friendly language.
  • Explain unavoidable jargon or link to docs/glossary.md.
  • Distinguish confirmed facts, evidence-backed inferences, proposals, and unknowns.
  • Do not overstate compatibility, production readiness, benchmarks, adoption, or search visibility.
  • When a change affects behavior, show the important test scenarios, expected outcomes, actual outcomes, commands, and evidence in the pull request.
  • State which checks were not run and why. Do not write “all tests pass” without supporting output.

Change discipline

Before editing, classify the change as editorial, implementation, normative, security-related, or release-related.

  • Trace current links, validators, prompts, and version references before changing them.
  • Keep one pull request focused on one coherent outcome.
  • Preserve meaning during moves; separate broad structural changes from normative changes.
  • Prefer the smallest defensible solution and the Python standard library.
  • Do not add a dependency, agent capability, MCP server, hook, or memory feature without a demonstrated need, owner, risk boundary, and removal plan.
  • Do not copy third-party text or code without checking its license and recording required attribution.
  • The executor may validate its own work, but a material change requires independent review before approval.

Privacy and safety

  • Never add private repository content, client or employer data, personal data, credentials, internal domains, or identifying logs.
  • Use synthetic examples and clearly fake values.
  • Do not run included prompts against production or paid external systems during repository maintenance.
  • Do not publish security details in a public issue, Discussion, pull request, screenshot, or log.

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.
