We Built a Reddit Lead-Finder Skill for Claude, Codex, and ChatGPT

A packaged skill that finds Reddit leads for a product — subreddit discovery, a fit/severity/intent rubric, rule checks, and a drafted report — as a native Claude Skill or a plain-markdown playbook for Codex, ChatGPT, or any agent.

We shipped a packaged skill — reddit-lead-finder— that turns the ThreadSnoop API into a finished workflow instead of seven endpoints someone has to wire together themselves: give it a product (a URL is enough, it'll read the site and confirm what it found with you), and it searches the right subreddits, judges every candidate on fit, severity, and intent, checks each subreddit's self-promotion rules, and hands back a short ranked report with quoted evidence and links. Two files, both free, both download from the ThreadSnoop homepage: a native Claude Skill and a plain-markdown twin for Codex, ChatGPT, or anything else that can make an HTTP call.

Why a skill instead of just docs?

An API is a set of capabilities; a skill is a finished way to use them. We'd already written the workflow up as a blog post — a prompt sketch you copy, tweak, and re-run by hand every time. A skill is that same workflow packaged so an agent picks it up on its own: Claude Code loads a real SKILL.mdautomatically when it's relevant, no slash command or re-explaining required, and any other agent gets the identical instructions as plain markdown to paste in once. Same judgment, same rubric, zero re-explaining per session.

What it actually does

  1. Reads the product from a URL, or asks.Give it a site and it fetches the page itself, infers what the product is, who it's for, and what problem it solves — then says that back to you and asks you to confirm or correct it before spending a single search. No URL, no problem — it just asks directly.
  2. Searches by problem, not by product category. search_subreddits finds communities from the pain, not the obvious industry name, and every sweep generates both category vocabulary (how a seller would describe it) and pain vocabulary (how someone with the problem actually complains about it, product-name-free) — the second is where most real leads live.
  3. Judges every candidate on three dimensions— the same rubric ThreadSnoop itself scores on: Customer Fit, Problem Severity, Purchase Intent. A post that merely mentions a topic doesn't make the report; one that shows real fit and real urgency does.
  4. Checks the subreddit's rules first. get_subreddit_rules before recommending anyone engage — plenty of communities ban self-promotion outright.
  5. Drafts a short report, not a data dump — permalink, the quoted line that convinced it, the three scores, one sentence of reasoning, ranked.

A real run, unscripted

We tested the skill against ThreadSnoop's own product — a Reddit read API built for AI agents — searching r/webscraping for people running into exactly the kind of problem the API solves. One hit, the kind the skill is built to surface:

“How to search multiple Reddit Communities at once? What is the best way to limit search on selected Reddit Communities at once?”
— r/webscraping

The top reply pointed at Reddit's own unauthenticated multi-sub .jsonendpoint, then immediately noted it “fails to work unless you're logged in” — a real developer hitting a real gap a stable, authenticated read API closes directly. Judged against the rubric: strong Customer Fit (a developer trying to do exactly what the API is for), moderate Problem Severity (a real blocker, not yet an expensive one), and low explicit Purchase Intent (they asked how to build it themselves, not what to buy) — a genuine, on-topic thread worth a helpful reply, not a five-alarm lead. That distinction — real signal without inflating it — is the whole point of scoring instead of just keyword-matching.

Get it

Both files are free downloads from the ThreadSnoop homepage, no signup required to grab them — you'll need a free API key to actually run the workflow (1,000 free Reddit searches on signup, no card):

  • Claude Code / claude.ai — download SKILL.md, drop it in .claude/skills/reddit-lead-finder/ (project or ~/.claude/skills/ for every project), and Claude loads it automatically when what you're doing matches its description.
  • Codex, ChatGPT, or your own agent — download reddit-lead-finder.md, a plain-markdown twin with the identical steps and rubric, meant to be pasted once as custom instructions or a system prompt.

Either file assumes a key you can call the REST API with:

curl
curl "https://api.threadsnoop.com/v1/subreddits/search?q=saas" \
  -H "x-api-key: YOUR_KEY"

or, if your agent supports MCP, connect https://api.threadsnoop.com/mcpinstead and it'll use the seven MCP tools in place of raw REST calls — see what the Reddit MCP server is for setup across Claude Code, Claude Desktop, and Codex CLI.

Curious how the underlying scoring works in the actual product, not just this skill's hand-rolled version of it? how ThreadSnoop finds customers on Reddit covers the real pipeline — keyword and semantic discovery, the same fit/severity/intent rubric, and the learning loop that tunes it to your own ratings over time.

Frequently asked questions

What is the reddit-lead-finder skill?

A free, downloadable playbook that uses the ThreadSnoop API to find Reddit posts and comments from people describing the problem a product solves, judges each one on customer fit, problem severity, and purchase intent, and drafts a short ranked report with links and quoted evidence.

Does it work with ChatGPT and Codex, or only Claude?

Both files ship together: a native Claude Skill (SKILL.md, auto-loaded by Claude Code and claude.ai) and a plain-markdown twin with the identical instructions for pasting into Codex, a custom GPT, or any other agent that can make HTTP calls.

Does the skill post or reply on Reddit automatically?

Never. It only reads and drafts — the same human-in-the-loop rule as every other ThreadSnoop surface. It hands you a link and an optional draft reply; you review, edit, sign in as yourself, and post it.

How much does it cost to run?

The skill itself is free. It calls the ThreadSnoop API, which is metered per request ($1.50 per 1,000 reads at the base rate) — new accounts get 1,000 free Reddit searches, no card required, which covers a real first run.
