agentproto-apps

agentproto-apps is a skill for Claude Code, Codex from agentproto/ts. It costs 178 tokens per session (3,075 once invoked), scanned A, original, Apache-2.0.

A package format and command set for building Agentproto apps: folders containing agents, workflows, an optional web interface, and app-specific data.

In plain words
What is it for?
Use it to create an app bundle, define its agents and workflows, serve its interface, manage its lifecycle, and read or write its stored data.
Why use it?
It gives these parts a defined structure and lets the Agentproto daemon install, run, monitor, stop, and store data for an app.

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.

Security

Grade A, and why

agentproto-apps 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 19d 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.

Agentproto apps (AIP-53)

A packaged app is a directory that ships one or more AIP-42 agents, the AIP-15 workflows they run, and (optionally) a single-file web UI, emitted under <dir>/.agentproto/ by defineApp().emit(dir). The daemon installs, applies, runs, and persists them. This skill is the app plane on top of the base agentproto skill (sessions/drivers live there).

Anatomy — what an app dir contains

<appDir>/
  .agentproto/
    APP.md                            # frontmatter: id, agents[], workflows[], ui{path,tools}
    agents/<id>/AGENT.md              # AIP-42 agent manifests
    workflows/<id>/WORKFLOW.md        # AIP-15 workflow manifests
    ui/index.html                     # single-file dashboard (CSS+JS inline)
  data/                               # default data dir (app_data_* writes here)
<dataDir>/                            # …or wherever `app_install {dataDir}` /
                                      # `app install --data-dir` pointed it

APP.md frontmatter (schema: app/v1, id, agents: [{id,path}], workflows: [{id,path}], ui: {path, title, tools: [...]}, optional data: {dir} — the default data dir, relative to the app dir). The ui.tools array is an allowlist — app_tool_call REFUSES any tool id not in it, so when the UI calls a new daemon tool (e.g. app_data_read), add it there.

Gotcha: this repo's root .gitignore ignores .agentproto/ by default (it targets agent-scoped scratch). For a first-class app bundle the .agentproto/ dir IS the deliverable — git add -f <appDir>/.agentproto to commit it.

The app lifecycle (daemon verbs)

  • app_install {dir} — validates the app (loadAppHandle), cross-checks every WORKFLOW.md tool step id against the daemon's registered tools (reports ALL missing at once), and checks the agent adapter resolves. Upserts by appId. Re-installing refreshes the record.
  • app_apply {appId, scopeId?, dir?} — makes the app's capabilities available in a scope; installs first if dir given and not already installed; validates requires deps are applied. Idempotent.
  • app_run {appId, agents?, sequence?, prompt?, cwd?, model?, harness?, adapter?} — spawns one live session per agent under a fresh appRunId. agents runs them CONCURRENTLY. sequence: [id, ...] runs them ONE-AT-A-TIME in order (each awaited to a terminal session state before the next), for scout→tailor-style dependency chains — both under one appRunId. Pass model/harness (or adapter) to select the runner for every spawn.
  • app_status {appRunId} — returns the run's session descriptors + its workflow runs. As of the sequential-run work, app_status LAZILY reconciles: if the stored run status is running but every session is terminal, it reports ended (with a synthesized endedAt) — so concurrent runs are also observed to conclude instead of hanging forever at running.
  • app_stop {appRunId} — kills the run's sessions and marks it terminal.
  • app_list — installed apps with a run-history summary (includes adapter/harness/model when set on the run).
  • app_uninstall / app_unapply / app_list_applied / app_catalog / app_skill_get / app_artifact_get — installation/uninstall and catalog.

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.
