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 | $0.00026 | $0.00271 |
| Opus 5.5 | $0.00010 | $0.00108 |
| Sonnet 5.5 | $0.00005 | $0.00054 |
| Haiku 4.5 | $0.00003 | $0.00027 |
Grade A, and why
rn-feature-dev 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
React Native Feature Development
Initial request: $ARGUMENTS
Invoke the rn-feature-development skill and execute the full 8-phase pipeline
against the user's feature request above.
The skill contains the complete process:
- Phase 1 (Discovery) through Phase 8 (E2E Proof)
- Core principles, safety constraints, and recovery procedures
- Common Rationalizations, Red Flags, Boundaries, Verification gates
Do not improvise the process. Follow every phase in the skill. Create a todo list at Phase 1 with all 9 phases (1, 2, 3, 4, 5, 5.5, 6, 7, 8) and mark each complete as you progress.
Critical reminders:
- NEVER skip phases — speed comes from parallel agents, not phase elimination
- Gate Phase 5 on explicit user approval of the architecture (from Phase 4)
- Phase 5.5 verification table MUST have concrete Evidence in every row
- Phase 8 executes the architect's E2E Proof Flow mechanically, step by step
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-feature-dev is a command published in the GitHub repository Lykhoyda/rn-dev-agent (20 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 271 once invoked, about $0.0001 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.
