Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00329 | $0.00329 |
| Opus 5 | $0.00164 | $0.00164 |
| Sonnet 5 | $0.00066 | $0.00066 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
ralph 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 3d 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
Ralph Agent Instructions
Overview
Ralph is an autonomous AI agent loop that runs AI coding tools (Amp or Claude Code) repeatedly until all PRD items are complete. Each iteration is a fresh instance with clean context.
Commands
# Run the flowchart dev server
cd flowchart && npm run dev
# Build the flowchart
cd flowchart && npm run build
# Run Ralph with Amp (default)
./ralph.sh [max_iterations]
# Run Ralph with Claude Code
./ralph.sh --tool claude [max_iterations]
Key Files

Flowchart
The flowchart/ directory contains an interactive visualization built with React Flow. It's designed for presentations - click through to reveal each step with animations.
To run locally:
cd flowchart
npm install
npm run dev
Patterns
- Each iteration spawns a fresh AI instance (Amp or Claude Code) with clean context
- Memory persists via git history,
progress.txt, andprd.json - Stories should be small enough to complete in one context window
- Always update AGENTS.md with discovered patterns for future iterations
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 snarktank/ralph (21,663 stars, last pushed 7mo ago), licensed MIT. It adds 329 tokens to every session, about $0.0016 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 2026-08-30.
