A consent-first setup wizard for configuring a Bridge assistant. It checks the system only with permission, suggests relevant features, and lists other available features.

In plain words
What is it for?
Setting up a new Bridge user, reconfiguring an existing one, reviewing suggested features, and browsing the feature catalogue.
Why use it?
It helps new users discover useful features without answering abstract questions or allowing unwanted system scans.

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

bridge-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 9d 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.

Bridge Onboard — Setup Wizard

Set up a new Bridge user or reconfigure an existing one. Read the referenced file ONLY when triggered.

Philosophy — Discover, don't Interrogate

A new user came here to configure an assistant, not to inventory their life. Asking abstract questions like "do you file taxes for multiple legal entities?" or "do you have a household mandant?" makes the user defensive — they don't know yet what those features do, so they say "skip" to everything and miss the point.

Instead, the wizard:

  1. Looks at what's already on the system (with permission)
  2. Proposes specific features that match the evidence
  3. Shows the rest as a read-only catalogue with "when you need it"
  4. Surfaces features proactively later (feature-discovery standing-order) when patterns suggest they'd help

All of this is consent-first: before step 1, the user picks discovery.modeconfined (default) or broader. Confined means the Bridge never scans the machine (other repos, installed apps, devices, files, and mail stay untouched) — you still get every feature, just enabled modularly when you want it via the Phase E catalog, --add <feature>, or the feature's enabled: flag in bridge-config.yaml. Only broader unlocks the permission-gated scan in step 1.

The entry point is the four-lane front door in rules/session-start.md § NEW USER front door — it reflects what Phase 0 detected (origin state, git name), notes the guard is already armed, and opens four discoverable lanes under a free-text invite: [1] show me around (demo) · [2] describe what I'll use it for (→ this wizard, purpose pre-filled) · [3] make it private first (protection) · [4] bind a workspace / org overlay. This file and references/ are where lanes [2]/[3]/[4] land; the heavy lifting lives in references/.

Defaults — what the wizard assumes

  • Purpose pins a north-star (ordering, never gating). It is captured at the front door — the user describes what they're here to do (session-start lane [2] or a free-text answer) and that sentence becomes purpose.statement verbatim; Phase A does not re-ask. purpose.focus and user_profile are derived silently from the statement — never posed as a visible six-domain questionnaire. Purpose ORDERS the Phase C suggestions, the Phase E catalogue, and (under broader) the feature-discovery standing-order; it never hides, gates, or removes a feature. Empty purpose = today's flat, general-purpose behaviour. Change anytime via --purpose.
  • GitHub is optional. Onboarding completes end-to-end without a GitHub org, without gh CLI, and without GitHub-projects integration.
  • Upstreams stay empty (upstreams: []) by default. Upstream variant choice is a separate, optional step via --upstream.
  • Work-system on by default. Phase D recommends enabling — it's what makes Claude resume context across sessions. The wizard explains the trade-off but suggests [y].
  • Discovery scan is opt-in per source. Default-on sources are non-invasive (git config, dir listings, app list). Sensitive sources (mail accounts, finance-app accounts, calendar names) are default-off and only opt-in.
  • Nothing scanned beyond names. Mail content, document content, message bodies, keychain, passwords — NEVER touched. Explicit in the permission prompt so trust is established.

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.

bridge-onboard is a skill published in the GitHub repository bks-lab/open-bridge (8 stars, last pushed yesterday), licensed MIT. It adds 135 tokens to every session and 2,488 once invoked, about $0.0007 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 2026-08-31.
