Solana Mobile dev skills

Agent skills for building Solana apps on Android with Expo and React Native. These follow the Agent Skills convention — a SKILL.md per skill directory — so they work with Claude Code, Codex, OpenCode, Cline, Amp, and the other agents the installer below supports.

The repository is also packaged as an Agent Plugin: the root plugin.json manifest plus the skills/ directory make it a portable plugin that compatible clients can discover and load directly.

Skills

Skill	What it covers
integration-privy	Privy authentication over Mobile Wallet Adapter, via Sign-In-With-Solana
seeker-domains	.skr domain resolution in both directions, with server and client integration
seeker-genesis-token	Seeker device ownership via SGT verification and Sign-in-with-Solana
solana-mobile	Project scaffolding, templates, emulators, development builds, toolchain checks
solana-mobile-wallet	Mobile Wallet Adapter: connect, disconnect, sign, send

Each skill is a self-contained directory: a SKILL.md with the procedure, and references/ with detail the agent loads only when it needs it. That keeps the up-front context cost small while the long-form material stays available.

Skills covering a third-party service are prefixed integration-, so they group together in a listing and stay distinguishable from the first-party ones.

Install

Use skills, the same installer npx solana-mobile create uses to add the Solana dev skill:

npx -y skills add solana-mobile/solana-mobile-skills

That prompts for which skills and which agents. To take everything without prompts:

npx -y skills add solana-mobile/solana-mobile-skills --all

Skills land in .agents/skills/, which most agents read directly, and are symlinked into the agent-specific locations that need it. A skills-lock.json records the source and a content hash of each skill, so installs are reproducible and reviewable in a diff.

Useful flags:

npx -y skills add solana-mobile/solana-mobile-skills -l          # list without installing
npx -y skills add solana-mobile/solana-mobile-skills -g          # install globally
npx -y skills add solana-mobile/solana-mobile-skills -s solana-mobile-wallet

Then skills list, skills update, and skills remove manage what is installed.

To install by hand instead, copy any skills/<name>/ directory into your agent's skills directory. Each one is self-contained, with no links outside its own folder.

Using them

Describe what you want; the agent picks the skill from its description. Things that trigger these:

• "Create a new Solana mobile app"
• "Add a connect wallet button to my Expo app"
• "Send SOL from my React Native app"
• "Gate this screen to Seeker owners"
• "Show .skr names instead of wallet addresses"
• "Add Privy login to my Solana mobile app"

In Claude Code you can also invoke one directly, for example /solana-mobile-wallet.

Requirements

• An Expo React Native project
• A development build — Expo Go does not work. Mobile Wallet Adapter needs native Android modules that Expo Go does not bundle. This is the most common cause of "the wallet integration does not work".
• An Android development environment. npx solana-mobile@latest doctor checks it.

Android only. iOS builds run, but have no wallet support.

Kit first

The skills write @solana/kit with @wallet-ui/react-native-kit — the current client library, and what npx solana-mobile create scaffolds. Patterns follow the expo-kit-minimal template.

They fall back to legacy @solana/web3.js with @wallet-ui/react-native-web3js in two cases: the app already uses it as its Solana client, or you ask for it directly. So the skills read package.json before writing wallet code, and match what is there rather than mixing stacks — provider props, hook return values, and transaction construction all differ, and code from one silently fails on the other.

The CLI

These skills lean on the solana-mobile CLI rather than restating setup steps that go stale:

npx solana-mobile@latest create      # scaffold from the template catalog

npx solana-mobile@latest doctor      # check the local toolchain

npx solana-mobile@latest emu start   # manage Android emulators

Scope

Mobile and Seeker-specific work only. For general Solana development — Anchor and Pinocchio programs, Codama client generation, testing, security review — use the Solana Foundation's solana-dev skill. npx solana-mobile create installs it into .agents/skills/solana-dev/ in every scaffolded project, so it is usually already present. These skills sit alongside it rather than duplicating it.

Contributing

Three checks run in CI, and all of them run locally. Validate against the Agent Skills spec with Anthropic's quick_validate.py from anthropics/skills, vendored at scripts/validate-skill.py and wrapped to add the checks it skips, such as the skill name matching its directory. Needs python3 with PyYAML (pip install pyyaml):

./scripts/validate-skills.sh

Then check that every relative link resolves and stays inside its skill directory, which the spec validator does not cover:

./scripts/check-links.sh

CI also validates plugin.json against the Agent Plugins schema. To run that locally:

curl -sfL https://agent-plugins.org/schemas/1.0.0/plugin.schema.json -o /tmp/plugin.schema.json &&
echo "0a4aad95ce337878ad38802ebf0daa3fde76abe3f65400c86bcbb1ec0b3ab883  /tmp/plugin.schema.json" | shasum -a 256 -c - &&
npx -y ajv-cli@5.0.0 validate --spec=draft2020 -s /tmp/plugin.schema.json -d plugin.json

Beyond what those enforce, skill content should stay portable across agents:

• Frontmatter carries name and description; name must match the directory name
• Relative links only, never pointing outside the skill's own directory — a skill directory is the unit of distribution, so an escaping link breaks once the skill is installed alone
• No host-specific tool names in the prose — describe the action, not the tool
• Keep SKILL.md under 500 lines and push detail into references/, so activation stays cheap

Issues and pull requests welcome. Prompts always have room to improve.
