Build and edit live Superwall paywalls from the CLI. Attach to a running browser editor session using a pairing code, list the tools the browser exposes right now, and invoke them. Covers native sw-* elements, editing workflow, design standards, and the attach/call/release lifecycle. Use whenever the user wants to design, build, modify, or review a Superwall paywall, onboarding, or web2app flow.

What this skill does

# Superwall Paywall Editor

Paywalls are built in a browser editor that exposes its tools over an authenticated relay. This skill drives that relay from the CLI — the exact same surface the MCP gateway uses — so every tool you invoke runs inside the live browser session the user has open.

## When to use

- The user wants to build, edit, or review a Superwall paywall, onboarding, or web2app flow.
- The user pastes a pairing code and asks you to take over editing.
- The user asks "what tools can you run right now?" — discover them via the browser, not from memory.

## Start here: attach, then discover

Never assume a tool name or signature from memory. The browser is the source of truth and its tool set changes across releases.

Preferred API launch flow:

1. Create an auto-expose URL: `scripts/sw-editor.sh expose --application-id <id> --paywall-id <id> --agent-name <agent> --open --wait`
2. Ask the user to complete browser authorization if prompted. The editor auto-exposes; do not ask them to click the expose button.
3. Discover what is available right now: `scripts/sw-editor.sh tools`
4. Invoke tools: `scripts/sw-editor.sh call <tool-name> --args '<json>'`

Fallback manual flow:

1. Ask the user for the **pairing code** shown in the editor UI.
2. Attach: `scripts/sw-editor.sh attach <pairing-code>`
3. Continue with `tools` and `call`.

Full CLI reference: [references/cli.md](references/cli.md).

## How to build and edit

- Workflow, build order, and when to use which tool: [references/workflow.md](references/workflow.md)
- Native `sw-*` elements (multiple-choice, indicator, drawer, picker, lottie, navigation): [references/native-elements.md](references/native-elements.md)
- Design standards, review checkpoints, typography, and conversion principles: [references/design.md](references/design.md)

## Orchestration rules

- Always establish an attachment before editing. Use `expose --open --wait` when possible, otherwise use `attach <pairing-code>`. `tools`, `call`, `status`, `release` all require an attached session.
- Prefer `expose --open --wait` when you have `SUPERWALL_API_KEY`, an application id, and a paywall id. It uses the same relay as manual pairing but removes the human pairing-code step.
- Before calling a tool you have not used this session, run `tools` to confirm it exists and to read the current parameter schema. Tools are defined in the browser bundle — an updated editor ships new or renamed tools without any change to this skill.
- Use `get_screenshot` (if present in the tool list) every 2–3 modifications to verify. Don't fly blind.
- Prefer semantic tools (`update_styles`, `set_text_content`, `set_dynamic_value`, `move_nodes`) over re-running `write_html` on existing structure. See `references/workflow.md`.
- Prefer native `sw-*` elements over hand-rolled `<div>` recreations whenever the UI represents a semantic control. See `references/native-elements.md`.
- When parsing CLI output, use `jq` — never Python. Example: `sw-editor.sh call get_subtree --args '...' | jq -r '.content[0].text'`
- Release when the user is done: `scripts/sw-editor.sh release`.

## When things go wrong

- `session_not_ready`: the browser disconnected or reloaded. Ask the user to bring the editor tab back, then re-attach (the pairing code rotates — they'll need to read you the new one).
- `session_locked`: another client is already attached. The user either attached from another MCP client, or a previous CLI attachment wasn't released. They can detach from the editor UI and you can retry.
- `unauthorized`: the controller token is stale — re-attach with a fresh pairing code.
- `attach_failed: provide a valid current pairingCode`: pairing codes expire after ~10 minutes and rotate on detach. Ask the user to show you the current one.

contribute

Included

Local-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".

architectural-analysis

Included

User-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).
