onboard

onboard is a command for Claude Code from zhangfengcdt/memoir. It costs 64 tokens per session (248 once invoked), scanned A, original, Apache-2.0.

A command that indexes the current folder and saves a persistent project overview in memoir. Git repositories receive a code-structure map, while non-Git folders receive a file-based index.

In plain words
What is it for?
Use it to onboard yourself or another coding agent to a repository or project folder. Pass the force option to rebuild the overview even when no changes are detected.
Why use it?
It lets later sessions start with stored context about the folder instead of rebuilding an overview each time. It also chooses an indexing method suited to the folder type.

Token cost

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.

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 8d 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.

What it actually says

Run the memoir-onboard skill. The skill picks the right procedure for the current folder:

  • git repocodebase:onboard (modules, goals, rules, lessons). Cold path on a fresh clone, warm path after meaningful diffs, meta-only when code HEAD hasn't moved.
  • non-git folderproject:onboard (per-file structured blobs from deterministic stdlib extractors, plus a project-shape summary). Tuned for writing, video editing, bookkeeping, and other mixed-media projects. Cold/warm/meta paths keyed off a filesystem snapshot hash.

Pass --force to rewrite even when nothing has changed since the last onboarding pass.

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.
