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

mdflow CLAUDE.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 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.

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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Overview

mdflow (md) is a CLI tool that executes AI agents defined as markdown files. It parses YAML frontmatter for configuration and passes keys directly as CLI flags to the specified command (claude, codex, gemini, copilot, or any other CLI tool).

CLI Subcommands

md <file.md> [flags]     # Run a flow (bare `md` opens the Flow Workbench)

                         # Scaffold a starter roster (deterministic, zero engine
                         # turns; --guided runs the interactive setup session)
md create [name]         # Create a flow and a fail-closed draft eval suite
md capture               # Print the guide an in-session agent follows to capture
                         # the current conversation as a flow (free; see src/capture.ts)
md explain <flow.md> [--json]  # Show resolved config without executing (free)
md render <flow.md>      # Inspect, write, or open a rendered flow explanation
md hooks add|list|remove <flow.md> [event…]  # Manage the flow's lifecycle hooks file (free)
md eval <flow.md>        # Run the flow's eval suite (costs engine turns; --plan is free)

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.
