onboard: Instructions file for Claude Code

CLAUDE.md

onboard CLAUDE.md is an instructions file for Claude Code from sdsrss/onboard. It costs 4,420 tokens per session, scanned A, original, MIT.

Repository instructions for the onboard Claude Code skill, a reusable workflow that helps agents inspect and prepare a project. They document its phases, versioning, checks, sharing modes, and plugin recommendations.

In plain words
What is it for?
Use them when developing, versioning, testing, or documenting the onboard skill and its installation or removal workflow.
Why use it?
They explain how this skill is structured and validated, so an agent can change it without confusing the skill itself with a normal application.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR} variable. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is sdsrss/onboard's own configuration. It tells Claude Code how to work on onboard itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything onboard configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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 CLAUDE.md 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 2mo 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this repo is

This repo is not an application — it is the /onboard Claude Code Skill itself (current version: v3.2.0). The "code" being maintained is:

  • skills/onboard/SKILL.md (v2.10 moved here from repo root) — the workflow spec defining a 10-phase onboarding protocol (Phase 0 / 0.5 / 1 / 1.5 / 1.7 / 2 / 2.5 / 3-8), Doctor Mode (--doctor, v2.5+; D1-D15 checks), Mode model (--local-only default vs --share, v2.6+), Install Plan / Plugin recommendation matrix (v2.7+), Uninstall Mode + marker/snapshot protocols (v2.8+), and Plugin marketplace install-source detection (v2.9+). v3.0 起 Phase 7 / Uninstall Mode / 状态文件结构 三段抽到 sub-file；v3.2 起新增 Plugin recommendation matrix 第 4 段 (skills/onboard/phases/phase-7.md / skills/onboard/phases/uninstall.md / skills/onboard/references/state-schema.md / skills/onboard/references/recommendations.md)；SKILL.md 原位置保留 sentinel header + 4-8 bullet summary + Read sub-file.md 指令；consumer Claude 进入对应 phase 前必须 Read sub-file（元规则 27）。This file's frontmatter (name: onboard, disable-model-invocation: true, allowed-tools: Read, Glob, Grep) registers it as a Skill — at skills/<name>/ for plugin discovery, or under standalone .claude/skills/onboard/ after install.sh.
  • skills/onboard/hooks/*.sh (v2.10 moved) — 4 hook scripts; git index mode 100755 (executable).
  • skills/onboard/settings.template.json + skills/onboard/settings.local.template.json (v2.10 moved) — reference configs for --share / --local-only modes; co-located with SKILL.md.
  • install.sh (v2.8, v2.10 redesigned) — universal installer (install/update/uninstall/doctor); uses staging cache at ~/.claude/.cache/onboard-source/ for fast updates; copies skills/onboard/* into install target.
  • .claude-plugin/plugin.json (v2.8, v2.9 schema-corrected) — Claude Code plugin manifest, canonical schema only.
  • .claude-plugin/marketplace.json (v2.9) — Claude Code plugin marketplace catalog at repo root; required for /plugin marketplace add sdsrss/onboard to find the plugin.
  • tests/run.sh + tests/integration/*.sh — in-repo sandbox tests for plugin install / hook execution / installer round-trip / SKILL.md link consistency / hook runtime behavior / v2.11 uninstall modes / v2.12 state-schema validation (224 assertions across 10 integration tests: plugin-install.sh 24 + hook-mirror.sh 33 + install-roundtrip.sh 38 + skillmd-links.sh 21 + hook-behavior.sh 55 + cc-plugin-detection.sh 8 + prepare-script-detection.sh 2 + sync-versions-detection.sh 1 + uninstall-modes.sh 21 + state-schema.sh 21); run via bash tests/run.sh. v2.11.1 adds scripts/verify-counts.sh to auto-check the headline+per-test claims here / in CHANGELOG against actual pass: counts — drift triggers non-zero exit. v2.11.2 adds scripts/release-preflight.sh which bundles verify-counts.sh + version-bump completeness + git update-index --chmod=+x on new .sh + staged-file sanity into a single pre-commit check. v2.11.3 adds .env boundary-anchored deny in guard-bash.sh (H1; 12 new hook-behavior assertions) + mirror-hooks.sh cmp -s fast path (L1; 4 new hook-mirror assertions) + inline _keeper_command_after_skill_uninstall doc fields in settings.local.template.json (M5) + install.sh Iron Law 14 stage-cache exemption comment (M4) + README "never auto-installs" 设计承诺 section. v2.12.0 adds ONBOARD_FORBIDDEN_COMMANDS newline-separated regex env in guard-bash.sh (H2; 11 new hook-behavior assertions) + per-stack lint_timeout_sec / typecheck_timeout_sec / format_timeout_sec / format_check_timeout_sec in stacks.json (H3; 4 new hook-behavior assertions) + scripts/validate-state.sh runtime state-schema validator + state-schema.sh integration test (C2; 21 new assertions). Persisted post-v2.10 from the prior /tmp/onboard-plugin-test.sh; hook-behavior.sh added in v2.10.2; cc-plugin-detection.sh / prepare-script-detection.sh / sync-versions-detection.sh / uninstall-modes.sh added in v2.11.0 for the 8 P-A items; state-schema.sh added in v2.12.0 for C2.
  • README.md — install + usage guide for end users.
  • CHANGELOG.md — version history.

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.
