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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00228 | $0.00995 |
| Opus 5 | $0.00114 | $0.00498 |
| Sonnet 5 | $0.00046 | $0.00199 |
| Haiku 4.5 | $0.00023 | $0.00100 |
Grade A, and why
lineth-quickstart 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 9d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lineth Stack quickstart — agent skill
This skill helps you operate the Lineth Stack quickstart: a Docker-Compose dev/demo stack that boots a local Linea/Lineth L2 settled by either Sepolia (default, real public L1) or a self-contained local Besu+Teku L1. It is a dev/demo tool, not a production deployment.
The skill does not restate the boot procedure — that has one source of truth in the package, and duplicating it here would let the two drift apart. Your job is to route to that source, then layer on the failure triage and change/commit rules the skill bundles.
Start here
Run everything from docs/getting-started/lineth-stack/ (find it with git rev-parse --show-toplevel
then cd in). Then read these two files before acting — they are the procedure, and if anything here
ever disagrees with them, they win:
AGENTS.md— the canonical operating runbook: preflight, L1-mode choice, the boot commands, the Sepolia funding stop, success signals, reset, and guardrails. Follow it step by step.README.md— the operator guide it draws on: endpoints, gas caps, prover modes, full troubleshooting.
Don't work from memory or from this file's summary — the stack is nonce/order-sensitive and
artifact-driven, so a 60-second read of the current AGENTS.md prevents a failed boot.
Two things agents most often get wrong
These are the classic false steps; AGENTS.md has the detail, but keep them front of mind:
- The Sepolia first-boot "exit" is expected, not an error. First Sepolia boot generates the
deployer keystore, prints the address + funding amount, and stops before any container starts. You
cannot fund it — surface the address to the human, then rerun the same command. For unattended runs,
choose
--l1-mode localinstead, which needs no funding. - Success means finality, not a blob. Report success only on an observed
finalizeBlocksand an advancing rollupcurrentL2BlockNumber.Submit Blobsonly publishes data — it is not finalization.
What ships with it
3 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.
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.

lineth-quickstart is a skill published in the GitHub repository LFDT-Lineth/lineth-monorepo (126 stars, last pushed today), licensed Apache-2.0. It adds 228 tokens to every session and 995 once invoked, about $0.0011 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.
