AGENTS.md

pantheon-legacy AGENTS.md is an instructions file for Codex, OpenCode from ils15/pantheon-legacy. It costs 799 tokens per session, scanned A, original, MIT.

A project instruction file for the Pantheon multi-agent system in Cline, an AI coding assistant. It documents available agents, their responsibilities, setup, commands, and working conventions.

In plain words
What is it for?
Configuring agent roles and workflows for frontend, database, research, planning, quality checks, and other development tasks.
Why use it?
It gives the coding assistant consistent project-specific rules and explains which agent should handle each type of work.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; built for cline.

This is ils15/pantheon-legacy's own configuration. It tells Codex and OpenCode how to work on pantheon-legacy itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pantheon-legacy configures →

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

pantheon-legacy 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 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.
