What is ralph AGENTS.md?

Instructions for Ralph, a framework that organizes coding-assistant workflows across Cursor, Claude, Codex, OpenCode, and Antigravity.

Use it when working on Ralph plans, YAML or Markdown task queues, multi-agent orchestration, agent profiles, runtime configuration, or artifact-based workflows.

It defines how work is planned, split into tasks, routed between assistants, and connected through shared files called artifacts.

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.

Model	Per session	Once invoked
Fable 5.1	$0.05179	$0.05179
Opus 5.5	$0.02072	$0.02072

Security

Grade B, and why

ralph AGENTS.md scanned grade B with 1 finding 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 2mo 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.

AGENTS.md

Audience: This file is the agent contract for Claude Code, Cursor, Codex, OpenCode, Antigravity, and other AI assistants working in this repository. Human operators should use README.md and docs/. Open a docs page only when this file points you there.

Overview

Ralph is a framework for organizing AI coding assistant workflows. It supports the Cursor, Claude, Codex, OpenCode, and Antigravity runtimes. It provides:

Plan-first loop: ralph create plan is the main entry point. --format classic is the zero-dependency markdown checklist path; --format yaml is the YAML-frontmatter TODO queue path. For staged multi-agent work, use ralph create orc. Older format tokens (standard, structured, pipeline, cursor) are still accepted as aliases for yaml.
Orchestration: Pipeline orchestration routes TODOs and stages by runtime, agent, and model across the supported runtimes (Cursor, Claude, Codex, OpenCode, Antigravity). It shares context through produces / requires artifact declarations and explicit artifact paths in TODO content so required inputs surface automatically in each stage's prompt.
Agents: Prebuilt agent profiles for specialized work (research, architect, implementation, code-review, qa, security)
Dashboard: Optional Node UI for monitoring plan execution and artifact generation

Ralph is installed into projects via ./install.sh. See Reference map → docs/INSTALL.md.

Runtime roots (this repo): .cursor, .claude, .codex, .opencode, and .agents at the repo root are project-owned directories for Ralph's own development workflow. bundle/.cursor/, bundle/.claude/, bundle/.codex/, bundle/.opencode/, and bundle/.agents/ are installable framework defaults and templates for downstream projects; editing bundle paths does not change repo-root runtime config. .ralph/ at the repo root is a symlink to bundle/.ralph/ (shared scripts); edits under bundle/.ralph/ are reflected there.

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.

ralph AGENTS.md is an instructions file published in the GitHub repository JoshJancula/ralph (10 stars, last pushed 1mo ago), licensed MIT. It adds 5,179 tokens to every session, about $0.0207 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
