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 | $0.03656 | $0.03656 |
| Opus 5.5 | $0.01462 | $0.01462 |
| Sonnet 5.5 | $0.00731 | $0.00731 |
| Haiku 4.5 | $0.00366 | $0.00366 |
Grade A, and why
openlakeforge 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 1mo 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 — 294 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent and contributor guide
This is the working guide for anyone changing OpenLakeForge — human or coding agent. It records what the repository actually enforces today. If a statement here disagrees with the code, the code wins and this file is a bug.
CLAUDE.md points here. There is one copy of these rules on purpose.
What this project is
OpenLakeForge is a cloud-agnostic, self-hostable lakehouse platform: open-source components assembled on Kubernetes with Terraform and Helm. The data path is CSV → Bronze → Floe validation → Silver Iceberg through Polaris → dbt-trino Gold → Trino → Superset, orchestrated by Dagster.
The audience is small data teams self-hosting a complete lakehouse. Runtime
footprint, onboarding friction, and recoverability are product features here,
not polish — a team without a platform engineer cannot absorb a stack that needs
one. v0.2-alpha is scoped around exactly that; see the roadmap.
Non-goals
These are settled scope decisions, not gaps. A change that adds machinery for one of them is out of scope, and a review finding that asks for it should be closed with a pointer here rather than fixed.
| Not a goal | Why |
|---|---|
Concurrent or re-entrant olf invocation |
olf is a single-operator CLI: one invocation at a time, on a workstation or a CI runner. olf deploy runs its phases sequentially in one process and relies on that. Do not add locks, leases, atomic-rename dances, or TOCTOU guards to shared code. |
| Windows support | Deployment targets are Linux and macOS. |
The audience is a small data team without a platform engineer, and that is a design constraint rather than a market description: machinery those teams will never exercise is not free. It costs runtime footprint, onboarding friction, and reviewer attention — the three things this project treats as product features.
This list is about the CLI process model, not about the deployed platform's
security. Authentication, credential scope, and stage data isolation in the
running stack are real requirements — open items are tracked as debt in
docs/technical-debt.md, not waived here.
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.

openlakeforge AGENTS.md is an instructions file published in the GitHub repository malon64/openlakeforge (22 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 3,656 tokens to every session, about $0.0146 per session on Opus 5.5. 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.
