Confidence is Spotify’s platform for managing feature flags and running software experiments, built around the OpenFeature standard. Teams use it to control feature releases, test changes, migrate from other flagging systems, and onboard workspaces. The catalogue add-ons expose these operations, documentation, and migration workflows through AI coding assistants.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00033 | $0.13587 |
| Opus 5 | $0.00016 | $0.06793 |
| Sonnet 5 | $0.00007 | $0.02717 |
| Haiku 4.5 | $0.00003 | $0.01359 |
Grade A, and why
onboard-confidence scanned grade A 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
**CRITICAL: TMPDIR differs between sandboxed and non-sandboxed Bash calls.** Sandboxed calls use a path like `/tmp/claude-501/`, while `dangerouslyDisableSandbox: true` calls use the system TMPDIR (e.g., `/var/folders/.. How it starts
The opening of the file, as written. The whole thing — 1,227 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Confidence Onboarding
Create accounts, invite users, and get started with Confidence — all from the CLI.
Default behavior (no sub-command)
When the user says "onboard me", "get started with Confidence", or triggers this skill without a specific sub-command, go straight to the setup wizard. The first question is always:
- Create a new account — I'll walk you through signup
- Sign in to an existing account — I already have one
Do NOT show a menu of sub-commands. Do NOT offer "Setup Wizard" as a choice — it IS the default flow. The only decision the user needs to make upfront is whether they have an account.
Commands
| Command | Description |
|---|---|
/onboard-confidence create-account |
Create a new Confidence account |
/onboard-confidence invite-user |
Invite a user to an account |
/onboard-confidence create-client |
Create an SDK client and generate credentials |
/onboard-confidence setup-wizard |
Guided walkthrough: client → flag → targeting → resolve |
/onboard-confidence setup-warehouse |
Configure data warehouse, connectors, and assignment tables |
/onboard-confidence learn |
Interactive learning about experimentation concepts |
/onboard-confidence status |
Check current user/account status |
Authentication
Browser-based Auth0 login. The skill opens a browser for Auth0 login (Google, email/password, SSO) and captures the token automatically. The user never touches a token.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-confidence is a skill published in the GitHub repository spotify/confidence-ai-plugins (10 stars, last pushed 4d ago), licensed Apache-2.0. It adds 33 tokens to every session and 13,587 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
