project-onboard

project-onboard is a skill for Claude Code from VKirill/claude-lane-stack. It costs 0 tokens per session (1,371 once invoked), scanned A, original, MIT.

A project-onboarding workflow that maps an existing code repository into practical documentation for developers and coding agents. It can create or update files such as a project guide, module map, API overview, test index, taxonomy, and runbook.

In plain words
What is it for?
Use it when starting work in a repository, especially when its project guide is missing or incomplete. It can perform a fast or deep onboarding and identify whether a user interface needs a separate design document.
Why use it?
It reduces the time needed to understand an unfamiliar repository and shows where its code, interfaces, tests, and design documentation are located.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

project-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 3d 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.

Project onboard (Claude Lane Stack)

Info (print and stop)

If $ARGUMENTS is info, or the user says info / справка / как запускать this skill: print the block below verbatim (Russian), then stop. Do not start onboard.

project-onboard — первичная карта репо (CLAUDE.md + LLM-pack)

Когда
- Нет CLAUDE.md / пустой или чужой репо.
- Уже живой UI без DESIGN.md → design-lead (project-design), не повторный onboard.

Как открыть шпаргалку
- /lane-stack:project-onboard info
- каталог: /lane-stack:info

Запуск
- /project-onboard
- /project-onboard deep
- /project-onboard /path/to/repo fast
- CLI: project-onboard .
- агент: project-onboarder (Codex, не Grok)

Флаги
- deep / fast — глубина
- full / minimal — scenario
- --seed-only — только заглушки, без модели

После
- RU-саммари: поверхности, модули, тесты, DESIGN?, RUNBOOK?
- has_ui → docs/DESIGN.md (Google)
- docs включены + паспорт тонкий → сначала этот скилл / project-onboarder, потом docs-maintainer
- weekly refresh: docs-maintainer, не этот скилл

Who runs it

Role How
One-shot CLI project-onboard . (detect + seed + Codex/Cursor fill)
Default writer Codex (stages.onboard from adoc)
Instructions ~/.agents/codex/instructions/onboard.md
Model / effort / fast adoc stages.onboard
Weekly refresh docs-maintainer (ONBOARD_REFRESH=weekly)
Existing UI, no DESIGN.md design-lead (skill project-design) — extract, do not re-onboard

Default CLI = full pipeline. --seed-only = stubs without model. Do not use Grok.

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.
