What is install-agentproto-app?

A setup tool that registers an agentproto app bundle with the local agentproto command-line service so it can find and run the bundle.

Use it to verify the command-line tool, install the current bundle, and start the service needed to run it.

It removes the need to manually add the bundle's location to the service's app registry.

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	$0.00055	$0.00526
Opus 5.5	$0.00022	$0.00210
Sonnet 5.5	$0.00011	$0.00105
Haiku 4.5	$0.00006	$0.00053

Security

Grade A, and why

install-agentproto-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 1mo 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.

What it actually says

Install this agentproto app

What this does

Registers this directory's .agentproto/APP.md-defined app with the local agentproto CLI, so the daemon (agentproto serve) can resolve it by id. This skill is intentionally generic — it does not read or care about whatever this particular bundle declares (book, kit, dashboard…); it only shells out to the one CLI verb every agentproto app installs through.

Steps

Confirm agentproto is installed and on PATH:
```
agentproto --version
```
If it isn't, install it first — npm i -g @agentproto/cli, or whatever this bundle's own README recommends.
From this directory (the one containing .agentproto/APP.md), run:
```
agentproto app install .
```
This reads the app's id from .agentproto/APP.md and registers id -> this directory in ~/.agentproto/apps.json — the same mapping the daemon's app_install tool writes. Re-running it for the same id is safe (idempotent): it updates the existing entry rather than erroring.
Make sure the daemon is running (skip if it's already up, e.g. as a background service):
```
agentproto serve
```
The app is now installed. What "using" it looks like from here depends on the client — the daemon's app_* MCP tools (app_run, app_apply, app_status, …), or agentproto app serve . for a standalone browser view, are both fair game. This skill's job stops at "installed and registered."

Gotchas

agentproto app install needs a .agentproto/APP.md in the target directory (an app dir, not an arbitrary folder) — run it from the app's root, or pass that root as the argument instead of ..
Installing an app is not the same as running it — this skill covers registration only.

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.
