A command-line tool for starting and managing local web and mobile application projects, including their development servers and previews.

It is for creating web or mobile projects from bundled templates, restarting servers, viewing logs, taking screenshots, building locally, and registering a Stripe webhook.

It puts common project setup, restart, logging, screenshots, builds, and checkpoints into one repeatable workflow.

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	$0.00034	$0.00991
Opus 5	$0.00017	$0.00495
Sonnet 5	$0.00007	$0.00198
Haiku 4.5	$0.00003	$0.00099

Measured 8d ago against content hash 93d034309fd5, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-07, from the pricing page.

Security

Grade A, and why

ii-app 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 8d ago.

The scan reads SKILL.md. This mod also ships 16 executable files (assets/templates/nextjs-shadcn/eslint.config.mjs, assets/templates/nextjs-shadcn/next.config.js, assets/templates/nextjs-shadcn/postcss.config.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

ii-app Skill

Use this skill for local app lifecycle actions that should go through the bundled Rust CLI:

ii-app web init <template_id> to scaffold a bundled web template and write a web cache
ii-app web restart to restart the cached tmux-backed web servers
ii-app web view-log to inspect web server output
ii-app web screenshot to open the cached preview URL in agent-browser, save a screenshot, and print the file path
ii-app web status to save server log output and a screenshot snapshot to disk, then print the status file path
ii-app web checkpoint to run bun run build:local, clean transient build artifacts, and create a git checkpoint commit
ii-app web list-templates to inspect bundled web template IDs
ii-app mobile init <project_name> to scaffold an Expo app and write a mobile cache
ii-app mobile restart to restart the Expo dev server and refresh tunnel/LAN URLs
ii-app mobile view-log to inspect Expo output
ii-app stripe register-webhook to create a Stripe webhook endpoint and write STRIPE_WEBHOOK_SECRET into the project .env

Workflow

Resolve the skill root as the directory containing this SKILL.md.

If bin/ii-app is missing or stale, build it with scripts/build.sh.
Run the binary from the skill root or by absolute path.
Prefer --json when another agent step needs structured output.
Use workspace-local caches unless the user asks for a custom --cache-path.

Default cache locations:

<workspace>/.ii-app/web.json
<workspace>/.ii-app/mobile.json

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.
