What is augment-extensions AGENTS.md?

Instructions for using Augment Extensions, a system that stores reusable guidance modules for the Augment Code AI agent. Its command-line tool can list, search, inspect, and link those modules to a project.

Use it to discover available modules, inspect their guidelines and examples, and apply linked rules while working on a project.

It lets an agent find the relevant project rules without relying on one small instruction file.

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.

Model	Per session	Once invoked
Fable 5.1	$0.04355	$0.04355
Opus 5.5	$0.01742	$0.01742
Sonnet 5.5	$0.00871	$0.00871
Haiku 4.5	$0.00436	$0.00436

Security

Grade A, and why

augment-extensions 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 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.

Augment Extensions - AI Agent Integration

This repository provides extension modules for Augment Code AI that exceed the standard .augment/ character limit.

For AI Agents

Discovery

You can discover and use extension modules through the augx CLI:

# List all available modules
augx list

# Show module details
augx show <module-name>

# Search for modules
augx search <keyword>

Usage in Projects

When working on a project that has Augment Extensions linked:

Check linked modules: augx list --linked
View module content: augx show <module-name>
Apply module rules: Follow the guidelines in the module's rules/ directory

Module Structure

Each module contains:

module.json - Metadata and configuration
rules/ - Markdown files with detailed guidelines
examples/ - Code examples demonstrating best practices
README.md - Module overview

Integration Workflow

Human initializes: augx init
Human links modules: augx link coding-standards/typescript
AI agent queries: augx show typescript-standards
AI agent applies rules from module content

CLI Commands Reference

augx list - List all available modules
augx list --linked - List modules linked to current project
augx show <module> - Display module content
augx show linked - Show all linked modules
augx show all - Show all available modules
augx search <term> - Search for modules
augx update - Update all linked modules
augx version - Show CLI version

Command Help Reference

When augx init is run, the CLI automatically generates .augment/COMMAND_HELP.md containing comprehensive help documentation for all detected workflow tools (Beads, OpenSpec, Augx).

For AI Agents:

Check for help reference: Look for .augment/COMMAND_HELP.md in the project
Use for command discovery: Reference the file to learn available commands and their syntax
Generate accurate commands: Use the help text to construct correct command invocations
Understand tool capabilities: Learn what each tool can do without executing commands

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.
