agent-plus AGENTS.md

A set of repository instructions for agent-plus, covering its coding-agent plugins, installation process, design patterns, and required planning practices. An AGENTS.md file is guidance that coding agents read before working in a project.

In plain words
What is it for?
Use it when installing or maintaining agent-plus, analyzing a repository, summarizing changes, or managing its skills and plugins.
Why use it?
It tells agents which commands and rules apply, reducing mistakes when using the repository's plugins, service wrappers, and workflows.

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.

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 D, and why

agent-plus AGENTS.md scanned grade D with 3 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 2d 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

curl -fsSL https://github.com/osouthgate/agent-plus/releases/latest/download/install.sh | sh

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- **Missing-config errors point to both `.env` and `~/.claude/settings.json`** so the user knows where to put the value.

AGENTS.md

Durable instructions for any coding agent (Claude Code, Codex, Cursor, Aider) working in this repo. If you're Claude Code, treat this as memory.

For context on what this repo is and why it exists, see README.md. This file is operational rules only.

Installing agent-plus

If asked to install agent-plus for the user, run:

macOS / Linux:

curl -fsSL https://github.com/osouthgate/agent-plus/releases/latest/download/install.sh | sh

Windows (PowerShell):

powershell -c "irm https://github.com/osouthgate/agent-plus/releases/latest/download/install.ps1 | iex"

Then register the plugins with Claude Code so they're callable as tools:

claude plugin marketplace add osouthgate/agent-plus
for p in agent-plus-meta repo-analyze diff-summary skill-feedback skill-plus; do
  claude plugin install $p@agent-plus
done

Then reload: /reload-plugins in the current session, or open a new one.

The install script chains into agent-plus-meta init automatically — the workspace wizard runs as part of install. If the user skipped that, they can run agent-plus-meta init manually.

Changes

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.

agent-plus AGENTS.md is an instructions file published in the GitHub repository osouthgate/agent-plus (4 stars, last pushed 1mo ago), licensed MIT. It adds 2,436 tokens to every session, about $0.0122 per session on Opus 5. A static security scan graded it D with 3 findings (downloads and executes remote code, reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
