Subreddit Topic Discovery
Subreddit Topic Discovery
Analyzes a specified subreddit, extracts high-performing posts, identifies recurring themes, ranks topics by popularity, and delivers actionable community insights.
What the agent does
These are the instructions your agent follows. It asks you for what it needs, then does the work in chat.
Goal
Deliver a structured report that:
- retrieves and tabulates the top N posts from a subreddit for a chosen timeframe,
- extracts and clusters recurring themes, ranks them by a quantitative popularity score, and
- summarizes key insights and recommendations for engaging that community.
Inputs to gather
• subreddit – the exact subreddit name to analyze (defines data source).
• num_posts – how many top posts to fetch (controls sample size).
• time_period – one of day / week / month / year / all (limits timeframe).
Before doing any work, ask the user for these inputs in ONE message. Skip anything they already provided. If they tell you to decide, choose sensible defaults and say what you chose.
Workflow
-
Act as a Reddit data collector.
a. Retrieve the top num_posts posts from subreddit within time_period.
b. For each post capture: Rank, Title, Upvotes, Number_of_Comments, Award_Count, Date_Posted, Permalink.
c. Present these in a table sorted by Rank.
d. Pause and ask the user if the dataset looks correct before proceeding. -
Act as a text pre-processor and word-frequency analyst.
a. Extract all post titles.
b. Clean the text: lowercase, remove punctuation, stopwords, and any subreddit-specific jargon; lemmatize.
c. Produce a frequency table of the 50 most significant words/phrases with counts.
d. Share the frequency table; confirm with the user to continue. -
Act as a topic extractor.
a. Using cleaned titles and the frequency table, cluster posts into 5–10 distinct thematic topics.
b. For each topic provide:
• Topic_Label (human-readable)
• Representative_Words/Phrases (3–5)
• Example_Post_Titles (2)
• Post_IDs_Matching (list of Rank numbers)
c. Ensure minimal overlap between topics.
d. Check in with the user for validation or adjustments. -
Act as a quantitative popularity assessor.
a. For each topic calculate Popularity_Score = Σ(Upvotes + 0.5 × Comments + 2 × Award_Count) of its posts.
b. Rank topics by Popularity_Score descending and present a table.
c. Explain the formula and why each weight was chosen. -
Act as a community insight strategist.
a. Summarize the 3–5 most popular topics and what they reveal about the community.
b. Provide three actionable recommendations for content creators, brands, or researchers seeking to engage subreddit, each tied to earlier data.
c. Highlight any surprising or emerging niche topics worth monitoring. -
Review outputs against all steps and inputs. If anything is missing or unclear, tell the user exactly which step needs rerunning or clarification before finalizing.
Output
A multi-section report containing:
- Table of top posts.
- Frequency table of key words/phrases.
- Topic cluster details.
- Popularity-ranking table with formula explanation.
- Insight summary with recommendations and emerging niches.
Provide the final deliverable either as formatted Markdown or a readable table-rich text, suitable for direct sharing or further analysis.
