aios-project-system

aios-project-system is a skill for Claude Code, Codex from rexleimo/aios. It costs 34 tokens per session (800 once invoked), scanned A, original, MIT.

A map of the AIOS repository's architecture, stored state, browser tools, skill sources, and execution rules. AIOS is a project system for coordinating coding-agent workflows.

In plain words
What is it for?
Use it before changing AIOS workflows, tasks, browser operations, skill synchronization, or other project-level automation.
Why use it?
It helps changes follow the repository's authoritative structure instead of editing generated files or bypassing required checks.

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

aios-project-system 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 5d 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.

AIOS Project System

Overview

Use this skill as the repository map for aios. It explains where state lives, how automation actually runs, and which files are authoritative before you edit tasks, workflows, or browser operations.

This skill is a map, not a router. For task routing, use aios-workflow-router; execute only the Provider selected by the current Rex Capability Command.

Core Topology

  • CLAUDE.md / AGENTS.md / GEMINI.md: per-client project-level behavior contract and architecture overview (each client loads its own instruction file).
  • skill-sources/*/SKILL.md: canonical skill sources (edit here, never edit generated copies).
  • Generated repo-local skills per client: .codex/skills, .claude/skills, .gemini/skills, .opencode/skills, .agents/skills — emitted from skill-sources/ via config/skills-sync-manifest.json.
  • Agent promotion and workflow enablement are evidence-gated: use agents smoke for core-risk rollout evidence, then skill verify-training to block changed skills until SkillOpt training is accepted.
  • scripts/lib/specs/*.json: runtime specifications and limits.
  • tasks/{pending,done,failed}: task queue and outcomes.
  • scripts/run-browser-use-mcp.sh: default browser MCP launcher (bridges to ai-browser-book/mcp-browser-use).
  • mcp-server/: legacy Playwright MCP implementation retained for compatibility workflows.
  • docs/plans/: design, implementation, and postmortem documents.

Runtime Truths (Do Not Skip)

  • The primary browser MCP server label is mcp-browser-use; do not add compatibility aliases for old browser MCP names.
  • mcp-server/src/index.ts still exposes Playwright browser_* tools, but treat that path as legacy/compatibility.
  • If both mcp-browser-use and chrome-devtools are available, use mcp-browser-use for normal browser automation and reserve chrome-devtools for debugging only.
  • For interactive runs, explicitly prefer chrome.launch_cdp { port: 9222, user_data_dir: '~/.chrome-cdp-profile' }, then browser.connect_cdp.
  • Repo-local skill SKILL.md files can drift from site UI; treat them as runbooks that require live verification.
  • Prefer page.extract_text / page.get_html evidence before using page.screenshot.
  • Repo-local discoverable skills are generated under each client's skill root (.codex/skills, .claude/skills, .gemini/skills, .opencode/skills, .agents/skills) from skill-sources/ — do not create ad-hoc skill roots such as .baoyu-skills/*/SKILL.md. .baoyu-skills/ is extension-config territory, not a skill root. Edit canonical sources under skill-sources/, then run skill sync.
  • Keep safety constraints aligned with scripts/lib/specs and the skill-constraints skill.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

aios-project-system is a skill published in the GitHub repository rexleimo/aios (52 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 800 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
