Implementation Reference

• src/tools/social-tools.ts:129-141 (handler)

  The handler implementation for reposting an event in Nostr (kind 6).

  export async function repostEvent({ eventId, eventPubkey, relayUrl, privateKey, relays }: z.infer<typeof repostEventSchema>) {
    const eTag = relayUrl ? ['e', eventId, relayUrl] : ['e', eventId];
    const template: EventTemplate = {
      kind: KINDS.REPOST,
      content: '',
      tags: [eTag, ['p', normalizePubkey(eventPubkey)]],
      created_at: Math.floor(Date.now() / 1000),
    };
  
    const signed = await signTemplate(template, privateKey);
    const result = await publishEvent(signed, relays ?? DEFAULT_RELAYS);
    return { event: signed, published: result };
  }

• src/tools/social-tools.ts:29-35 (schema)

  Zod schema definition for input validation of the repostEvent tool.

  export const repostEventSchema = z.object({
    eventId: z.string().describe('ID of the event to repost'),
    eventPubkey: z.string().describe('Pubkey of the event author'),
    relayUrl: z.string().optional().describe('Relay URL where the original event lives'),
    privateKey: z.string().optional().describe(privateKeyDesc),
    relays: z.array(z.string()).optional().describe('Relays to publish to'),
