Implementation Reference
- The async handler function that fetches user posts and replies from Discourse using the user_actions API endpoint, paginates with offset, formats post details including topic title, date, URL, category, and excerpt, and returns formatted text content or error.
async ({ username, page }, _extra: any) => { try { const { base, client } = ctx.siteState.ensureSelectedSite(); const offset = (page || 0) * 30; // The filter parameter 4,5 corresponds to posts and replies const data = (await client.get( `/user_actions.json?offset=${offset}&username=${encodeURIComponent(username)}&filter=4,5` )) as any; const userActions = data?.user_actions || []; if (userActions.length === 0) { return { content: [{ type: "text", text: page && page > 0 ? `No more posts found for @${username} at page ${page}.` : `No posts found for @${username}.` }] }; } const posts = userActions.map((action: any) => { const excerpt = action.excerpt || ""; const truncated = action.truncated ? "..." : ""; const date = action.created_at || ""; const topicTitle = action.title || ""; const topicSlug = action.slug || ""; const topicId = action.topic_id || ""; const postNumber = action.post_number || ""; const categoryId = action.category_id || ""; const postUrl = `${base}/t/${topicSlug}/${topicId}/${postNumber}`; return [ `**${topicTitle}**`, `Posted: ${date}`, `Topic: ${postUrl}`, categoryId ? `Category ID: ${categoryId}` : undefined, excerpt ? `\n${excerpt}${truncated}` : undefined, ].filter(Boolean).join("\n"); }); const totalShown = userActions.length; const pageInfo = page && page > 0 ? ` (page ${page})` : ""; const header = `Showing ${totalShown} posts for @${username}${pageInfo}:\n\n`; const footer = totalShown === 30 ? `\n\nTo see more posts, use page ${(page || 0) + 1}.` : ""; return { content: [{ type: "text", text: header + posts.join("\n\n---\n\n") + footer }] }; } catch (e: any) { return { content: [{ type: "text", text: `Failed to get posts for ${username}: ${e?.message || String(e)}` }], isError: true }; } } ); - Zod schema for tool input: required 'username' string and optional 'page' non-negative integer for pagination.
