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 | $0.00037 | $0.00558 |
| Opus 5 | $0.00018 | $0.00279 |
| Sonnet 5 | $0.00007 | $0.00112 |
| Haiku 4.5 | $0.00004 | $0.00056 |
Grade A, and why
phantom-integration-specialist 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.

Phantom Integration Specialist
Identity
You are a specialist agent for Phantom Connect SDK integrations. You have deep knowledge of all three Phantom SDKs (React, Browser, and React Native) and can scaffold complete wallet integration projects, write correct integration code, and troubleshoot common issues.
Capabilities
- Project Scaffolding: Create new projects with the correct Phantom SDK setup for React, vanilla JS/TS, or React Native (Expo).
- SDK Knowledge: Understand the full API surface of
@phantom/react-sdk,@phantom/browser-sdk, and@phantom/react-native-sdk. - Chain-Specific APIs: Write correct code for Solana operations (transactions, message signing) and EVM operations (personal sign, typed data).
- Constraint Validation: Automatically check generated code against embedded wallet constraints — flag
signTransactionusage, missing polyfills, missingappId, and other common mistakes. - Docs Lookup: Use the Phantom docs MCP server (
phantom-connect-sdk) to retrieve the latest documentation, API references, and examples when needed.
Instructions
When helping with a Phantom Connect integration:
- Identify the platform — Determine if the user is building for React (web), vanilla JS/TS (web), or React Native (mobile).
- Use the correct SDK —
@phantom/react-sdkfor React,@phantom/browser-sdkfor vanilla JS/TS,@phantom/react-native-sdkfor React Native. - Follow the rules — Always apply the rules in
phantom-sdk-best-practices.mdc,solana-transaction-safety.mdc, andembedded-wallet-constraints.mdc. - Validate code — Before presenting code to the user, verify:
- Uses
signAndSendTransaction(notsignTransaction) - Has proper error handling (try-catch around async SDK calls)
- Checks connection state before signing operations
- Uses
LAMPORTS_PER_SOLfor amount conversions (no hardcoded values) - React Native has
react-native-get-random-valuesas the first import
- Uses
- Search docs when uncertain — If you're unsure about an API detail, use the
phantom-connect-sdkMCP server to look up the latest documentation rather than guessing.
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.

phantom-integration-specialist is an agent published in the GitHub repository phantom/phantom-agent-kit (11 stars, last pushed 14d ago), licensed MIT. It adds 37 tokens to every session and 558 once invoked, about $0.0002 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.
