Getting it into your agent
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.
npx agentmods add instructions/rexleimo/aios/claude-mdgit clone --depth 1 https://github.com/rexleimo/aiosWhat 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 | $0.03418 | $0.03418 |
| Opus 5 | $0.01709 | $0.01709 |
| Sonnet 5 | $0.00684 | $0.00684 |
| Haiku 4.5 | $0.00342 | $0.00342 |
Grade B, and why
aios CLAUDE.md scanned grade B 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 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.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Path Conventions (路径约定)
IMPORTANT: All relative paths in this document are relative to the PROJECT ROOT (current working directory), NOT AIOS_ROOT.
Two Key Paths
-
AIOS_ROOT/AIOS_ROOT_DIR- AIOS framework installation location- Contains
scripts/,package.json, core framework code - Example:
/Users/rex/.rexcil/aiosor~/aios-framework - Set via environment variable or auto-detected
- Contains
-
Project Root - Your current working directory where you run AIOS commands
- Contains
.aios/,.claude/skills/,docs/plans/, project-specific state - This is where
pwdpoints when you runaioscommands - All paths in this document like
.aios/context-db/,.claude/skills/are relative to this directory
- Contains
Why This Matters
- If your
AIOS_ROOT=/Users/rex/.rexcil/aiosbut you're working in/Users/rex/my-project/:.aios/context-db/means/Users/rex/my-project/.aios/context-db/(✓ correct)- NOT
/Users/rex/.rexcil/aios/.aios/context-db/(✗ wrong)
- Framework scripts live in
$AIOS_ROOT/scripts/ - Your project state lives in
$(pwd)/.aios/
Verification Commands
# Check your project root
pwd
# Check AIOS framework location
echo $AIOS_ROOT
# List your project's AIOS directories
ls -la .aios/ .claude/skills/ docs/plans/
Evaluate the AIOS workflow policy before creating a plan, selecting a skill, or dispatching work.
directandnoopturns do not create a persistent plan or invoke a skill chain.guardedturns use only the required edit and verification gates.plannedturns create or reuse one work-item plan, then execute only the Provider selected by the current rex Command.- Do not insert a global bootstrap or compatibility skill chain.
aios-workflow-routerhelps classify work but does not replace the Provider selected by the current Rex Capability Command. - Invoke the selected Provider rather than paraphrasing it; use
verification-before-completionbefore claiming a changed behavior is complete.
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.
