onboard

A project setup tool for Claude Code that examines an older codebase and creates project guidance in CLAUDE.md. It can also configure guard hooks, restricted areas, health checks, and matching local and continuous-integration commands.

In plain words
What is it for?
Use it when introducing Claude Code to a legacy project, generating CLAUDE.md, configuring safeguards, checking setup health, or removing the setup.
Why use it?
Older projects often lack clear instructions for coding agents, and their local checks may differ from CI. This tool gathers that information and organizes the setup, with a local-only mode that avoids writing project files.

Security

Grade A, and why

onboard 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.

What ships with it

1 file beside plugin.json 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.

Changes

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.

onboard is a plugin published in the GitHub repository sdsrss/onboard (2 stars, last pushed 3mo ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-08-31.
