Agentlas OS is a local-first system for creating, storing, borrowing, and running specialist AI agents and temporary agent teams through supported hosts and models. It serves people who want reusable agents that remain available across computers and model workspaces, and the catalogue contains its skills, commands, hooks, agents, instructions, plugin, and rule.
Borrowing it
Nothing to install: this file belongs to agentlas-ai/Agentlas-OS. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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 | $0.00582 | $0.00582 |
| Opus 5.5 | $0.00233 | $0.00233 |
| Sonnet 5.5 | $0.00116 | $0.00116 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
Agentlas-OS CLAUDE.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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Adapter
Asked to install this repo, not to work on it? This file is the contributor constitution and will not help you. Read the install block at the top of README.md: it points at
scripts/install-all-runtimes.sh, which writes only under~/.agentlas,~/.local/bin, and this host's own plugin/command-adapter directories.
This file adapts the Agentlas Core Engine Meta-Agent Team for Claude Code.
AGENTS.md is canonical; this file stays thin.
Public Release Boundary
The Public Release Allowlist (Hard Rule) in AGENTS.md is mandatory.
For public GitHub work, stage only end-user install/runtime files and public
README/LICENSE/CHANGELOG material. Never stage internal docs, research,
benchmarks, tests or fixtures, logs/results, signing or credential material,
environment files, private paths/memory, or unrelated local work. Verify the
staged archive, not the dirty working tree.
Route
- Read
AGENTS.md. - Read
.agentlas/mode-map.json. - Use
skills/mode-classification/SKILL.mdto choose the mode. - If missing details would change files, adapters, or public/private boundary,
use
skills/clarify-question-loop/SKILL.md. - Route to one core team member:
agents/10-single-agent-builder/agent.md;agents/20-multi-agent-team-builder/agent.md;agents/30-agentlas-packager/agent.md;agents/40-session-agent-builder/agent.md.
- Load only matching
skills/*/SKILL.md. - Use
skills/agentlas-auto-activation/SKILL.mdwhen local project continuity or.agentlasactivation is part of the output. - Keep runtime-specific files as adapters over the canonical core.
- Use
.agentlas/global-commands.jsonto create and report the generated global command.
Use When
/meta-agent- single agent builder
- agent team builder
- package an existing local or external agent
- Agentlas architecture packaging
- Codex, Claude Code, Antigravity, Cursor, or AGENTS.md compatibility
- generated global command routing
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.
