duplicacy-mcp: Instructions file for Codex

AGENTS.md

duplicacy-mcp AGENTS.md is an instructions file for Codex, OpenCode from GeiserX/duplicacy-mcp. It costs 1,206 tokens per session, scanned C, original, GPL-3.0.

A project instruction file for the duplicacy-mcp repository. It tells a coding agent which shell commands and file operations to use, including non-interactive and recursive commands.

In plain words
What is it for?
It is for guiding agent work on the duplicacy-mcp codebase, especially command execution and file overwrites.
Why use it?
It gives the agent project-specific rules instead of making it infer them from the code. This can reduce unsafe prompts, unnecessary confirmations, and inconsistent command use.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is GeiserX/duplicacy-mcp's own configuration. It tells Codex and OpenCode how to work on duplicacy-mcp 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 duplicacy-mcp configures →

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 C, and why

duplicacy-mcp AGENTS.md scanned grade C 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 21d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.
