post-install-onboarding

post-install-onboarding is a command for coding agents from Evol-ai/SkillCompass. It costs 0 tokens per session (674 once invoked), scanned B, original, MIT.

A first-use setup routine for SkillCompass, a tool that evaluates and tracks agent skills. It runs when the tool is installed, reinstalled, or updated.

In plain words
What is it for?
Use it during the first interaction after setup or an update to scan installed skills, save the scan results, and show whether any risks were found.
Why use it?
It gives the agent an initial introduction and checks installed skills for security or structural problems. This helps surface risky skills before they are used.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the SkillCompass plugin — 1 skill, 14 commands, 3 hooks shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/evol-ai/skillcompass/post-install-onboarding
Clone the repo
git clone --depth 1 https://github.com/Evol-ai/SkillCompass

Or install SkillCompass, the plugin that ships this one along with the rest of its 1 skill, 14 commands, 3 hooks.

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 B, and why

post-install-onboarding scanned grade B with 1 finding 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 4d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Check whether `~/.claude/settings.json` already has a `statusLine` configured.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Post-Install Onboarding

Triggered by the SessionStart hook (hooks/scripts/session-tracker.js), which compares the current SkillCompass version against the last recorded version. On first install, reinstall, or version change the hook injects a context message instructing Claude to load this file and follow it on the user's first interaction.

Do not wait for a slash command. Execute the steps below in order as soon as the session starts.

Step 1: Introduce

🧭 SkillCompass

Evaluate skill quality, find the weakest area, and improve it.
Also tracks usage to help you spot idle or risky skills.

Step 2: Quick Scan (automatic, no permission needed)

Silently run skill discovery — scan immediate children */SKILL.md in each skill root (same as /setup Step 3; do NOT recurse) — and run a D1+D2+D3 quick scan on every discovered skill. Save the results to .skill-compass/setup-state.json. Then show one of the two result summaries below.

If any risks found:

Scanning installed skills...

Found {N} skill(s){, including M collections if any}.
{K} have security or structural risks; the rest passed the quick scan ✓

[View risky skills / Continue]

If all clean:

Scanning installed skills...

Found {N} skill(s){, including M collections if any}, all passed the quick scan ✓

[Continue]

Step 3: StatusLine Configuration

Check whether ~/.claude/settings.json already has a statusLine configured.

If NO existing statusLine:

SkillCompass tracks skill usage automatically.
When suggestions exist, the status line shows 🧭 N pending — type /skillcompass to view.

[Enable status line 🧭 / Skip]

If the user chooses Enable, offer two modes:

[Minimal — just the 🧭 hint / Full HUD — model, context, and more]
  • Minimal: write the statusLine config to ~/.claude/settings.json pointing to scripts/hud-extra.js.
  • Full HUD: check for claude-hud; if present, configure its --extra-cmd; otherwise fall back to Minimal.
  • Skip: do nothing.

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.
