Freshness Gate

Current Unix timestamp: !date +%s

Read your MEMORY.md and find the last_fetch_date value. If it does not exist, or if the current timestamp minus last_fetch_date exceeds 604800 (7 days), you MUST run a knowledge refresh before answering. Follow the refresh procedure described in your agent system prompt (fetch SDK repos, release notes, and NIP support tables — write findings to agent memory only, never modify plugin files).

If memory is fresh, proceed directly to answering.

Reference Documents

The following supporting documents are available in your skill directory at ${CLAUDE_SKILL_DIR}/:

File	Content
library-matrix.md	All major Nostr SDKs by language/maturity/NIP support/activity, with strengths and trade-offs
selection-guide.md	Decision tree by language, platform, and use case; when to push back on a user's chosen library
common-tasks.md	Side-by-side code examples for keypair generation, publish, subscribe, and NIP-46 connect across SDKs
interop-and-bindings.md	rust-nostr UniFFI family, the two distinct nostr-sdk-ios projects, archived/legacy projects, wire compatibility

Read the relevant documents to answer the user's question. Consult your agent memory for additional context and prior findings.

Response Format

• Default to language-native first. Match the user's stack rather than pushing one SDK universally. nostr-tools/NDK for TS, rust-nostr for Rust, fiatjaf.com/nostr for Go, pynostr for Python, nostr-sdk-ios for native Apple, etc.
• Surface bindings as a fallback when cross-platform parity matters (rust-nostr → nostr-sdk-jvm + nostr-sdk-swift).
• Always check archive/legacy status before recommending: go-nostr is archived (use fiatjaf.com/nostr), python-nostr is feature-frozen (use pynostr), NostrKit is minimal (use nostr-sdk-ios), Rhodium is incomplete (use nostr-sdk-jvm for KMP).
• Show concrete code for the chosen library — don't just name it.
• Cite NIP numbers when explaining behavior; defer to the remote-signing skill for deep NIP-46/07/55 specifics.
• Flag pre-1.0 / alpha status (rust-nostr family, marmot-ts, Rhodium).
• Watch out for name collisions — distinguish rust-nostr/nostr-sdk-swift (UniFFI) from nostr-sdk/nostr-sdk-ios (native) from damus-io/nostr-sdk (Damus's own implementation).
• If you need to fetch live source or release notes to verify an API surface, do so.
