What is brandapp-sdk-install?

A setup workflow for adding the reopt Brandapp SDK to a project. The SDK provides building blocks for sign-in, OAuth, custom data fields, subscription checkout, file handling, API routes, and environment settings.

Use it when first installing or initializing @reopt-ai/brandapp-sdk, setting up authentication or payments, adding file support, or configuring its API routes and environment variables.

It gives the project-specific setup steps needed for these parts to work together, including changes between SDK versions.

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	$0.00105	$0.03170
Opus 5	$0.00053	$0.01585
Sonnet 5	$0.00021	$0.00634

Security

Grade A, and why

brandapp-sdk-install 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.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Brandapp SDK Install

This is NOT the SDK you know. Read node_modules/@reopt-ai/brandapp-sdk/docs/ before writing code (the package ships docs at top-level docs/, not dist/docs/). Heed deprecation notices — 2.0 renamed every env var without aliases; 3.0 rewrote the webhook contract and blocks clientSecret in the browser; 4.0 moved to Better Auth 1.7 (no client plugin, new callback path). docs/migration.md stops at 2.x → 3.0.0, so read the package CHANGELOG.md for 3.1–4.0.

When to apply

A consumer project adopting @reopt-ai/brandapp-sdk for the first time. Triggers: "install", "init", "setup", "bootstrap", "apply SDK", "brandapp integration" against @reopt-ai/brandapp-sdk.

Step 1 — Pin agent rules into AGENTS.md / CLAUDE.md

Source of truth for the rules block: the module's own agent-rules file, once it ships one. @reopt-ai/brandapp-sdk does not ship one as of 4.2.0, so use the fallback agent-rules.md bundled with this skill.

Append to the consumer's AGENTS.md (fall back to CLAUDE.md if AGENTS.md is absent — never both). Wrap the content between:

<!-- BEGIN:reopt/brandapp-sdk-agent-rules -->
…content from source above…
<!-- END:reopt/brandapp-sdk-agent-rules -->

Idempotent: if the markers already exist, replace only the content between them. Never touch text outside the markers — the consumer's own rules live there.

Step 2 — Consumer-side setup (this skill owns; docs cannot)

These are properties of the consumer project, not the module. They will not appear in the module's docs/.

Public npm registry — no token or scoped .npmrc entry is required. Inspect the project .npmrc and npm config get @reopt-ai:registry; if the scope still resolves to GitHub Packages, remove only the legacy project entry @reopt-ai:registry=https://npm.pkg.github.com before installing. Preserve unrelated registry/auth settings, and ask before changing user/global npm config.
Env namespace (2.0+) — 3 tiers, no aliases for renamed vars:

What ships with it

3 files 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.

Changes

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.

brandapp-sdk-install is a skill published in the GitHub repository reopt-ai/reopt-skills (1 stars, last pushed 7d ago), licensed MIT. It adds 105 tokens to every session and 3,170 once invoked, about $0.0005 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 2026-08-31.
