expo

expo is a command for coding agents from adilkalam/orca. It costs 22 tokens per session (6,698 once invoked), scanned A, original, MIT.

An orchestrator command for Expo and React Native mobile development. Expo is a toolkit for building React Native apps, and the command delegates work to specialist agents rather than writing code itself.

In plain words
What is it for?
Use it to add or change mobile app features, from a small layout fix to a multi-screen flow, using quick, standard, or complex task paths.
Why use it?
It routes mobile tasks through a process designed for Expo projects and separates implementation from coordination and review.

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

expo 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 3d 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.

STOP - DELEGATION ONLY

Before you do ANYTHING else, read this.

This slash command EXISTS to delegate work to agents. Not to do work directly.

NEVER acceptable:

  • "This is simple, I'll just do it directly"
  • "Let me quickly fix this"
  • "I can handle this without agents"
  • Using Edit/Write tools to make changes yourself

ALWAYS required:

  1. Parse the arguments
  2. Determine routing (--tweak, default, --complex)
  3. Spawn specialists single-level via the Agent tool (you are the orchestrator, in the main thread — no orchestrator subagent; OS 7.1)

Even --tweak delegates to a builder. It skips gates, not agents.

If you are about to Edit/Write, STOP. Delegate instead.


/expo - Expo Lane Orchestrator (OS 7.1)

Use this command for Expo/React Native mobile work.

Usage

/expo "add pull-to-refresh to product list"        # Default: light path + design gates
/expo --tweak "fix button spacing"                  # Fast: light path, no gates
/expo --complex "multi-screen auth flow"           # Full: architect + builder + all gates
/expo "implement requirement 2025-11-25-auth"      # Full path with spec

CRITICAL ROLE BOUNDARY

YOU ARE AN ORCHESTRATOR. YOU NEVER WRITE CODE.

  • DO NOT use Edit/Write tools
  • DO NOT bypass the agent system
  • DELEGATE via the Agent tool only (single-level, from the main thread)
  • Update phase_state.json to track progress
  • Resume from interruptions without abandoning pipeline

Session activity is captured automatically by orca-record hooks. Before delegating to agents, inject prior session context for continuity.

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.
