What it does

Lineth Quickstart is an agent skill from LFDT-Lineth/lineth-monorepo. Operating manual for the Lineth Stack quickstart — the Docker-Compose dev/demo stack at docs/getting-started/lineth-stack in the lineth-monorepo that boots a local Linea/Lineth L2 with Sepolia or local L1 finality. Use whenever you are working inside the lineth-stack quickstart and need to boot or run the stack, choose between local and Sepolia L1 mode, get past the Sepolia deployer-funding step, read the finality/success signals, run traffic or bridge smoke tests, reset it, or debug a failing boot (L1 RPC…

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `metadata.json`, `rules/debugging.md` and `rules/making-changes.md`).

It sits in Development, covering Monorepo tooling, Containers and QA and bug reports. It works with Docker and Ethereum. The repository describes itself as: The principal Lineth repository. Lineth is an enterprise-grade EVM layer 2 framework for developing public, permissioned or private networks. Its modular and versatile design… The licence is AGPL-3.0.

When your agent uses it

  • You are working inside the lineth-stack quickstart and need to boot
  • Choose between local and Sepolia L1 mode
  • Get past the Sepolia deployer-funding step
  • Read the finality/success signals

Example prompts

  • “start the stack”
  • “run the quickstart”
  • “boot lineth locally”
  • “/lineth-quickstart”

Requirements

  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit 75baf30. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Lineth Quickstart loads about 1k tokens when it runs. Until then it costs about 240 tokens; SKILL.md has 423 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~240
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Use whenever you are working inside the lineth-stack quickstart and need to boot or run the stack, choose between local and Sepolia L1 mode, get past the Sepolia deployer-funding step, read the finality/success signals, run traffic or bridge smoke tests, reset it, or debug a failing boot (L1 RPC unreachable, deploy gas too low, unfunded deployer, port collision, prover out-of-memory, address mismatch, finality not advancing). Trigger even on casual asks — "start the stack", "run the quickstart", "boot lineth locally", "my deploy keeps failing", "finality isn't happening", "reset the quickstart". When editing this package's scripts or docs, also read rules/making-changes.md so commits pass the repo's lint and DCO gates.

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 local instead, which needs no funding.
  • Success means finality, not a blob. Report success only on an observed finalizeBlocks and an advancing rollup currentL2BlockNumber. Submit Blobs only publishes data — it is not finalization.

When something fails

Read rules/debugging.md — it has a symptom → cause → fix table (RPC unreachable, gas too low, unfunded deployer, port collision, prover OOM, address mismatch, finality not advancing), the logs-first diagnostics, and timing expectations so "slow" isn't mistaken for "broken". Hard STOP conditions that need a human: an unfunded Sepolia deployer and repeated Sepolia gas/RPC failures.

When you change scripts or docs in this package

Read rules/making-changes.md — read-before-change, the validation gate (./scripts/check-quickstart-static.sh plus a real boot for boot-path changes), and the repo's commit rules that reject otherwise-fine commits: scope must be from the allowed list (use misc; lineth-stack is rejected), git commit -s for DCO, and a GitHub noreply author email or the push is blocked. Never commit .env, artifacts/, or any real secret.
