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.

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 | $0.06215 | $0.06215 |
| Opus 5 | $0.03107 | $0.03107 |
| Sonnet 5 | $0.01243 | $0.01243 |
| Haiku 4.5 | $0.00622 | $0.00622 |
Grade A, and why
Agentlas-OS 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 today.
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

Repository Constitution: Local Main Only
This repository uses one canonical development line: the local main branch
in the canonical Agentlas OS checkout.
- Make every source change and commit directly on local
main. - Do not create feature, release, backup, agent-named, or temporary branches.
- Do not create Git worktrees. Use an external recovery directory or a verified Git bundle when a safety snapshot is required.
- Before editing, confirm the canonical checkout is on
main, inspect status, fetch remote refs, and inspectmain...origin/main. A GUI "Pull origin" button is not permission to pull or merge blindly. - If local
mainis dirty, preserve it with a reviewed checkpoint commit before reconciling remote changes on that same branch. - Push only
mainand intentional release tags. Do not publish side branches.
Public Release Allowlist (Hard Rule)
Before any commit, push, tag, release, or upload to a public GitHub repository,
construct and review an explicit allowlist. Public source and release artifacts
may contain only files required for an end user to install and run the product,
plus public-facing README, LICENSE, and CHANGELOG material.
Never publish internal design or research documents, plans, benchmarks, benchmark prompts or results, tests, fixtures, test data, scores, logs, screenshots, signing material, certificates, credentials, environment files, operator notes, private paths, local memory, or recovery artifacts. Run tests and benchmarks only in local/private temporary storage or private CI; publish neither their inputs nor their artifacts. Existing unrelated local work must remain unstaged.
For a public release, do not use a blanket git add -A. Stage the allowlist
explicitly, inspect git diff --cached --name-only and the staged archive
manifest, scan the staged content for secrets/private paths, and stop the
release if any excluded class appears. A passing test does not authorize
publishing the test.
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.

Agentlas-OS AGENTS.md is an instructions file published in the GitHub repository agentlas-ai/Agentlas-OS (1,099 stars, last pushed yesterday), licensed Apache-2.0. It adds 6,215 tokens to every session, about $0.0311 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 2026-09-03.
