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 | $0.00021 | $0.00302 |
| Opus 5 | $0.00010 | $0.00151 |
| Sonnet 5 | $0.00004 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
observe scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
The observe web UI autostarts when the session begins in an RN project. Permanent opt-out:
.rn-agent/config.json → { "observe": { "autoStart": false } } (port via observe.port,
default 7333; env RN_AGENT_OBSERVE_AUTOSTART / RN_AGENT_OBSERVE_PORT override config).
The user's argument: "$ARGUMENTS"
- If the argument is empty: call the
observeMCP tool withaction: "status". If running, print the returnedurlprominently and tell the user to open it in a browser to watch the live tool-call timeline, live device mirror, and app state. If NOT running (autostart disabled or previously stopped), callaction: "start"— an explicit /observe is an explicit request to see the UI — and print the URL. - If the argument is
stop: call withaction: "stop". The UI stays down for the rest of the session; mention the config opt-out if the user wants it permanent. - If the argument is
restart: call withaction: "restart"and print the (possibly new) URL. The event timeline is preserved across restarts.
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.

observe is a command published in the GitHub repository Lykhoyda/rn-dev-agent (11 stars, last pushed 2d ago), licensed MIT. It adds 21 tokens to every session and 302 once invoked, about $0.0001 per session on Opus 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.
