A guided onboarding and memory-curation tool for an AI assistant. It can set the assistant's name and personality, learn about the user, or update the assistant's profile and individual memory files.

Use it for first-run setup, changing the assistant's personality, updating the user profile, or deciding whether to keep, update, or delete one specified memory file.

It gives first-time setup a defined conversation and lets you make focused updates later without changing unrelated information. The saved details go into the assistant and user profile files.

SkillSpector: 3 findings, up to medium

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 →

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
medium Excessive Agency · line 168
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00154	$0.05609
Opus 5	$0.00077	$0.02805
Sonnet 5	$0.00031	$0.01122
Haiku 4.5	$0.00015	$0.00561

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 11d 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.

Skill: onboard

Purpose

"Onboard" here means the whole life of getting the assistant and user to know each other. That includes both the first-run ceremony AND every small course-correction later on. This single skill covers three modes, dispatched by the invocation arguments:

Args	Mode	What it does
(none)	first-run	Full intro: name the AI, pick personality, learn user, write soul.md + user.md.
`scope:soul`	curate SOUL	Short chat to tweak `~/.octo/soul.md` only.
`scope:user`	curate USER	Short chat to tweak `~/.octo/user.md` only.
`path:<abs>`	curate memory	Short chat to update / keep / delete one memory file at the given path.

lang:zh or lang:en may be combined with any mode to pin the language. Missing lang: → infer from the user's first reply, or from the existing file's language for curate modes, defaulting to English.

Dispatch

Parse the invocation message first, before greeting:

Look for path:<something>. If present → curate memory mode, skip to section C.
Otherwise look for scope:soul or scope:user. If present → curate profile mode, skip to section B.
Otherwise → first-run mode, start at section A.

Look for lang:zh / lang:en anywhere in the same line and use it to set the language.

Presenting choices

Whenever you offer the user a fixed set of options (personality, permission mode, reasoning effort, the curate-action menu, soul/user/memory keep-or-rewrite, etc.), present them with the ask_user_question tool — never as a plain markdown list. The tool renders as clickable cards in the web UI and an arrow-key picker in the terminal; a markdown bullet list is just text the user cannot click. Put each option's label + a short description in the tool's options, and rely on its built-in "Other" choice for free-text answers. Genuinely open prompts (the user's name, occupation, links) stay plain prose — those have no fixed options.

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 skill published in the GitHub repository open-octo/octo-agent (97 stars, last pushed yesterday), licensed MIT. It adds 154 tokens to every session and 5,609 once invoked, about $0.0008 per session on Opus 5. 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 2026-08-30.
