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 | $0.00777 | $0.00777 |
| Opus 5 | $0.00388 | $0.00388 |
| Sonnet 5 | $0.00155 | $0.00155 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
agent-toolkit 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 yesterday.
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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Run ox agent prime at session start to load SageOx team context — it's fine to read the user's request first.
AI Agent Instructions
ox is SageOx's team-context CLI. It is optional for outside contributors — if you do
not have it, skip the line above and carry on; nothing in this repository needs it to
build, test, or run.
Orientation
An opinionated toolkit for hosted AI chat agents that run on several chat surfaces at
once from one process and identity. Read README.md for the architecture and
SETUP.md to run one.
The property every change has to preserve: the brain holds no transport or write credential. It can only request actions through one guarded chokepoint, and the gateway decides and executes. If a change lets a credential, a relay handle, or a write path reach the brain's process, it is wrong however well it works.
Build and test
Node 22+ and pnpm 10. The vault tests shell out to real age
and age-keygen binaries, so install those too — or run mise install, which the
checked-in .mise.toml pins.
pnpm install --frozen-lockfile
pnpm test # vitest
pnpm typecheck # tsc --noEmit, root and every package
Both must be green before you open a pull request. Changes under deploy/ also need Helm
and Terraform; .github/workflows/ci.yml has the exact
commands and pinned tool versions.
Run the CLI from source with the checked-in wrapper — the packages are not published yet:
./bin/sageox-agent --help

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.

agent-toolkit AGENTS.md is an instructions file published in the GitHub repository sageox/agent-toolkit (10 stars, last pushed today), licensed Apache-2.0. It adds 777 tokens to every session, about $0.0039 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 2026-09-10.
