Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00091 | $0.04339 |
| Opus 5.5 | $0.00036 | $0.01736 |
| Sonnet 5.5 | $0.00018 | $0.00868 |
| Haiku 4.5 | $0.00009 | $0.00434 |
Grade A, and why
rn-workflow 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 28d 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.
How it starts
The opening of the file, as written. The whole thing — 329 lines — stays where its author put it; the contents beside it link to each section on GitHub.
rn-workflow — the proven operating sequence, in order
This domain skill owns the sequencing of a real React Native journey on
Codex. The authoritative content stays where it lives today: the check-env
playbook owns inventory, the setup playbook owns onboarding,
capturing-proof owns evidence gates, and the rn_session tool owns every
refusal. Execute the steps below in order; never reorder, skip, or re-derive
them from memory.
Each step is: one action → one authoritative readback → one bounded stop.
There is no internal state to track — the only state ever consulted is a fresh
rn_session(action="status") projection.
Package identity
Resolve the package root from this exact SKILL.md path (../.. from this
skill directory). The bundled checker lives INSIDE the installed package at
<package-root>/rn-dev-agent-core/dist/workflow-check.js. Never use a
plugin-root environment variable, marketplace source path, or cache scan.
When to use
- Before any journey that will touch a simulator/emulator (build, test, proof).
- When asked to "get the app ready", "validate the setup", or after repeated session/device failures.
When NOT to use
- Pure code reading or editing with no device work — no session is needed.
- Plugin installation diagnostics — that is the
doctorplaybook ($rn-dev-agent:doctor). - Project onboarding — that is the
setupplaybook ($rn-dev-agent:setup; Step 0 stops and routes there if onboarding is missing).
The contract
0 read instructions ─► 1 pkg-manager + deps ─► 2 read-only inventory
│
2a classify ownership (status only)
▼
3 one exact device ─► 4 integration + managed Metro ─► 5 bind + requested proof
│
6 truthful evidence ─► 7 reverse cleanup + postflight
Authority bounds — one copy, one target
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.

rn-workflow is a skill published in the GitHub repository Lykhoyda/rn-dev-agent (20 stars, last pushed today), licensed MIT. It adds 91 tokens to every session and 4,339 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
