[meta] Contributor onboarding roadmap

[abhicris]

Welcome, contributors

This is the contributor onboarding roadmap for arbitrum-cli — an agent-first Arbitrum CLI (JSON in, JSON out, MCP-compatible, single Rust binary).

Every issue below is scoped to be doable by a motivated outside contributor — no private context required.

The ladder

Tier 1 — good first issue (1–5 hours):

• Issues labeled good first issue. Topics: --pretty JSON flag, events subcommand, enriched info output.

Tier 2 — help wanted (1–2 days):

• Issues labeled help wanted. Topics: Orbit-chain support, extended Create Protocol AgentDeposit actions, MCP server mode (see MCP server mode: expose CLI subcommands as a local MCP server #1).

How to claim

1. Comment "I'd like to work on this" on the issue.
2. PR within ~1 week. Say so if life gets in the way.
3. cargo test && cargo clippy -- -D warnings must pass before review.

Learn the codebase

• PR feat: agent-deposit command + GitHub Actions CI #2 (feat: agent-deposit command + GitHub Actions CI) is the best read — shows the subcommand pattern + unsigned-calldata invariant.
• src/main.rs — clap subcommand enum; adding a new subcommand is a 30-line change.
• src/output.rs — the JSON/Human emit decision; every subcommand feeds through it.

Invariants

• The CLI never touches private keys. Writes always emit unsigned calldata; external signers broadcast.
• JSON by default (agent-first); humans use --human.
