The tool, available via Claude Code marketplace or npx for 50+ agent hosts, requires zero configuration for Reddit, HN, Polymarket, and GitHub, with a setup wizard unlocking additional sources. It aims to provide real-time insights beyond traditional search engines, which often miss platform-specific content.", "body_md": "English | [Français](/mvanhorn/last30days-skill/blob/main/README.fr.md) | [Deutsch](/mvanhorn/last30days-skill/blob/main/README.de.md) | [Español](/mvanhorn/last30days-skill/blob/main/README.es.md) | [Português (Brasil)](/mvanhorn/last30days-skill/blob/main/README.pt-BR.md) | [日本語](/mvanhorn/last30days-skill/blob/main/README.ja.md) | [简体中文](/mvanhorn/last30days-skill/blob/main/README.zh-CN.md)\n\n**An AI agent-led search engine scored by upvotes, likes, and real money - not editors.**\n\nThis README tracks the current v3 pipeline. The runtime skill spec lives in [skills/last30days/SKILL.md](/mvanhorn/last30days-skill/blob/main/skills/last30days/SKILL.md), which is the source of truth for the latest command and setup behavior.\n\n**Claude Code (recommended — auto-updates via marketplace):**\n\n```\n/plugin marketplace add mvanhorn/last30days-skill\n/plugin install last30days\n```\n\n**Codex, Cursor, Copilot, Gemini CLI, or any of 50+ Agent Skills hosts:**\n\n```\nnpx skills add mvanhorn/last30days-skill -g\n```\n\n(`-g`\n\ninstalls globally for your user, available across all projects. Drop it to scope per-project.)\n\nMore install options (claude.ai web, OpenClaw, manual) in the [Install](#install) section below.\n\nZero config. Reddit, HN, Polymarket, and GitHub work immediately. Run it once and the setup wizard unlocks X, YouTube, TikTok, arXiv, Techmeme, and more in 30 seconds.\n\nReddit upvotes. X likes. YouTube transcripts. TikTok engagement. Polymarket odds backed by real money and insider information. That's millions of people voting with their attention and their wallets every day. /last30days searches all of it in parallel, scores it by what real people actually engage with, and an AI agent judge synthesizes it into one brief.\n\nGoogle aggregates editors. /last30days searches people.\n\nYou can't get this search anywhere else because no single AI has access to all of it. Google search doesn't touch Reddit comments or X posts. ChatGPT has a deal with Reddit but can't search X or TikTok. Gemini has YouTube but not Reddit. Claude has none of them natively. Each platform is a walled garden with its own API, its own tokens, its own auth. But you can bring your own keys and browser sessions, and suddenly an AI agent can search all of them at once, score them against each other, and tell you what actually matters.\n\nThat's the unlock. Not one better search engine. A dozen disconnected platforms, bridged by an agent.\n\n```\n/last30days Peter Steinberger\n```\n\nYou have a meeting tomorrow. You Google them. You get their LinkedIn from 2023. /last30days gives you what they're actually doing this month: joined OpenAI to work on Codex, fighting Anthropic's ban on third-party agents, shipping 23 PRs at 85% merge rate, building \"LobsterOS\" for cross-device agent control, and r/ClaudeCode hit 569 upvotes debating whether he's a hero or \"insufferable.\" Scattered across X posts, Reddit threads, YouTube transcripts, and GitHub commits. None of it was on Google.\n\nI built it to keep up in AI. Everything changes every day and the Reddit and X nerds are always on top of it first. I needed better prompts, and the training data was always months behind what the community had already figured out.\n\nBut it turned into something bigger. Now I run it before a sales call to know the last 30 days truth about a business. Before a meeting to read someone's recent tweets and podcast transcripts. Before a Disney World trip to know which rides are closed and what the community says about Genie+. Before I build anything to know what problems people are actually hitting.\n\nIf you're meeting with a CEO, have you read all their tweets and YouTube transcripts from the last 30 days? I have.\n\n| Source | What the people tell you |\n|---|---|\nReddit |\nThe unfiltered take. Top comments with real upvote counts, free, no API key. The real opinions that Google buries. |\nX / Twitter |\nThe hot take, the expert thread, the breaking reaction. First to know, first to argue. |\nYouTube |\nThe 45-minute deep dive. Full transcripts searched for the 5 quotable sentences that matter. |\nTikTok |\nThe creator reaching 3.6M people with a take you'll never find on Google. |\nInstagram Reels |\nThe influencer perspective with spoken-word transcripts. The visual culture signal. |\nHacker News |\nThe developer consensus. 825 points, 899 comments. Where technical people actually argue. |\nPolymarket |\nNot opinions. Odds. Backed by real money. 96% confidence on album sales. 4% on an acquisition. |\nGitHub |\nFor people: PR velocity, top repos by stars, release notes. For topics: issues and discussions. |\nDigg |\nCurated story clusters from Digg's AI 1000 leaderboard (~1000 high-signal AI accounts on X), with attributable inline quotes (no X auth required). Auto-enabled when `digg-pp-cli` is on PATH. |\narXiv |\nThe papers behind the hype. New research in the window, free, no API key. Auto-enabled when `arxiv-pp-cli` is on PATH (first-run setup installs it). |\nTechmeme |\nThe tech-news editorial layer, date-windowed to your 30 days. Free, no API key. Auto-enabled when `techmeme-pp-cli` is on PATH (first-run setup installs it). |\nLinkedIn |\nThe professional signal. Posts and articles, with articles weighted as high signal. |\nStockTwits |\nTrader sentiment. Auto-activates when your topic is a ticker or crypto. |\nThreads |\nThe post-Twitter text layer. Conversations from creators and brands. |\nPinterest |\nVisual discovery. Pins, saves, and comments on products and ideas. |\nXiaohongshu (RED) |\nChinese lifestyle, product, and creator signals. Requested explicitly with `--search xhs` when a logged-in x-mcp browser plugin or `xiaohongshu-mcp` service is running locally. |\nBluesky |\nThe decentralized social layer. AT Protocol posts from the post-Twitter migration. |\nPerplexity |\nGrounded Sonar synthesis, raw Search API rows, and Deep Research. |\nWeb |\nThe editorial coverage, the blog comparisons. One signal of many, not the only one. |\n\nCommunity contributors keep adding more. Truth Social and other niche sources are in the engine with more on the way.\n\nA Reddit thread with 1,500 upvotes is a stronger signal than a blog post nobody read. A TikTok with 3.6M views tells you more about what's culturally relevant than a press release. Polymarket odds backed by $66K in volume are harder to argue with than a pundit's guess.\n\nThe synthesis ranks by what real people actually engaged with. Social relevancy, not SEO relevancy.\n\n**Before a meeting.** `/last30days Peter Steinberger`\n\n- joined OpenAI's Codex team, fighting Anthropic's ban on third-party agents, 23 PRs merged at 85% merge rate on GitHub, building LobsterOS for cross-device agent control. r/ClaudeCode: \"Ever since OpenClaw released, it was widely known that if you run it through anything other than the API, you were gonna get banned eventually\" (227 upvotes). That's not on LinkedIn.\n\n**To read hiring signals.** `/last30days Listen Labs --hiring-signals`\n\n- current jobs and careers pages become cited evidence for focus shifts: hiring into enterprise security, customer success, infrastructure, or product expansion. The report says what the hiring appears to signal, not what the roadmap will ship.\n\n**To find the topic before it peaks.** Ask `/last30days what's exploding in AI agents?`\n\nand the skill switches to discovery mode: the engine sweeps Reddit category listings, Hacker News front/best stories, Digg's AI 1000 feed, and X when authenticated; your agent judges the nominations (names, junk filtering, content-worthiness) and writes podcast / X-article angles; then you get 5-10 velocity-ranked topics. Every result includes cross-source numbers, a momentum label, and a ready-to-run `/last30days \"<topic>\"`\n\nfollow-up.\n\n**When something drops.** `/last30days Kanye West`\n\n- UK blocked his visa, Wireless Festival canceled, sponsors fled. But BULLY debuted #2 on Billboard. Fantano came back from his \"Yay sabbatical\" to review it (653K views). SoFi Homecoming brought out Lauryn Hill and Travis Scott for 44 songs. Polymarket: \"Will Kanye tweet again?\" 86% Yes. 23 Reddit threads, 17 YouTube videos, 86K upvotes.\n\n**To compare tools.** `/last30days OpenClaw vs Hermes vs Paperclip`\n\n- \"These aren't competitors, they're layers.\" OpenClaw is the executor (351K GitHub stars, live), Hermes is the self-improving brain (31K stars), Paperclip is the org chart (49K stars). Star counts pulled live from the GitHub API, not stale blog posts. Side-by-side table with architecture, memory, security, best-for. Per @IMJustinBrooke: \"OpenClaw = Charmander, Hermes = Charizard.\"\n\n**To understand the world.** `/last30days Iran vs USA`\n\n- Day 38 of the war. Trump's Tuesday deadline for Iran to reopen the Strait of Hormuz. Two US warplanes downed. Oil at $126/barrel. The IEA called it \"the largest supply disruption in the history of the global oil market.\" Polymarket: ceasefire by Dec 31 at 74%. 27 X posts, 10 YouTube videos, 20 prediction markets.\n\n**Before a trip.** `/last30days Universal Epic Universe`\n\n- Expansion already under construction. \"Project 680\" permit filed. Fireworks show confirmed by infrastructure but unannounced. Wait times: Mine-Cart Madness averaging 148 minutes. No annual pass yet, and locals are frustrated. Stardust Racers down for refurbishment through April 5.\n\n**To learn something fast.** `/last30days Nano Banana Pro prompting`\n\n- JSON-structured prompts are replacing tag soup. @pictsbyai's nested format prevents \"concept bleeding.\" Edit-first workflow beats regeneration. Then it writes you a production prompt using exactly what the community said works.\n\nSince the v3.3 announcement in May, as of v3.11.1 (July 2026): 175 merged PRs - 122 of them from 52 community contributors - across 15 releases. This is what landed.\n\n/last30days is now a native Codex plugin with guided setup - not a port, a first-class citizen. Renderer-aware citations mean Codex output reads like a brief instead of URL soup (#694), and the same engine runs on Claude Code, Cursor, Copilot, Gemini CLI, Claude Desktop, OpenClaw, and 50+ Agent Skills hosts. Codex plugin manifest by [@rfoust](https://github.com/rfoust) (#686), Codex auth fix by [@tmchow](https://github.com/tmchow) (#698).\n\narXiv brings the papers behind the hype and Techmeme brings the editorial tech-news layer - free, zero keys, and first-run setup installs their CLIs so they activate automatically (#709). Digg's AI 1000 story clusters arrive without X auth the same way - setup installs the free Digg CLI for you (#590). Trustpilot ships opt-in for consumer-brand research.\n\nReddit's public .json API died; the free path came back stronger. Keyless RSS + shreddit scraping (#457), dedicated-subreddit discovery with real upvote counts via arctic-shift (#696), and a relevance floor so a viral off-topic post can't hijack your brief (#488, thanks [@rzachsmith](https://github.com/rzachsmith)). No API key. Real scores. Top comments included.\n\nComments are now a default-on layer across sources: Instagram comments with rank-based diversity so five hot takes don't all come from one post (#751), YouTube comments plus a ScrapeCreators transcript backup for when yt-dlp strikes out (#637), and crowd-voted comments weighted into Best Takes so the community's funniest lines survive scoring (#592, #608).\n\nAsk for a health check and the doctor runs every source, then prescribes exact fixes - which key is missing, which CLI is off PATH, which cookie expired (#753). No more guessing why X came back thin.\n\nThe X pipeline got a ground-up overhaul: FROM and ABOUT lanes so a person's own posts and the conversation about them both rank (#610), person-aware subquery disambiguation (#611), first-party authorship grounding with interaction-signal ranking (#613), and a single X source with automatic backend failover (#622). Plus an honest `--diagnose`\n\nthat actually probes auth (#609).\n\nLinkedIn via ScrapeCreators, with articles as high signal ([@ravstr](https://github.com/ravstr), #702). StockTwits auto-activates for ticker and crypto topics ([@wtiwana](https://github.com/wtiwana), #658). Perplexity grew direct API modes and async Deep Research ([@sk-holmes](https://github.com/sk-holmes), #629).\n\nThe security wave was almost entirely community work: stored-XSS fixes in the HTML renderer ([@iliaal](https://github.com/iliaal), [@aaronjmars](https://github.com/aaronjmars)), locked-down cookie temp files, supply-chain-hardened CI with OpenSSF Scorecard and build provenance attestation ([@shaanmajid](https://github.com/shaanmajid), [@hammadxcm](https://github.com/hammadxcm), [@aniruddh909](https://github.com/aniruddh909)), Semgrep and OSV-Scanner scans plus a PR dependency-review gate ([@23241a6749](https://github.com/23241a6749)), a test-coverage floor introduced at 60% and since raised to 84% ([@gourab5139014](https://github.com/gourab5139014)), and a Hermes security scan cleared of every CRITICAL finding (#768).\n\nHebrew and non-Latin languages ([@dudyme](https://github.com/dudyme)). CJK-aware tokenization for Chinese sources ([@An-idd](https://github.com/An-idd)). A Windows compatibility wave. Cookie extraction across the full Chromium family - Brave, Edge, Vivaldi, Opera, Arc ([@andrey-esipov](https://github.com/andrey-esipov)) - plus macOS Keychain and Linux pass(1) credential sources. `--as-of`\n\nhistorical lookback ([@chiyi-creator](https://github.com/chiyi-creator)). Auto-provisioned Python 3.12 via uv ([@buntysomroy](https://github.com/buntysomroy)). `--hiring-signals`\n\nfor reading a company's job pages. Watchlist deltas between runs.\n\nThe v3 foundations are all still here: the pre-research brain that resolves the right handles, subreddits, and hashtags before a single API call fires (built by [@j-sperling](https://github.com/j-sperling)); Best Takes scoring for humor and virality alongside relevance; cross-source cluster merging; single-pass comparisons (\"CLI vs MCP\" in 3 minutes, not 12); auto-discovered `--competitors`\n\ncomparisons; GitHub person-mode (`--github-user=steipete`\n\n); ELI5 mode (\"eli5 on\" after any run); and shareable, self-contained HTML briefs (`--emit=html`\n\n). Configuration knobs live in [CONFIGURATION.md](/mvanhorn/last30days-skill/blob/main/CONFIGURATION.md).\n\n| Surface | Install | Updates |\n|---|---|---|\nClaude Code (recommended) |\n`/plugin marketplace add mvanhorn/last30days-skill` |\nAuto via marketplace, or `claude plugin update last30days@last30days-skill` |\nGrok (xAI Build CLI) |\n`grok plugin marketplace add mvanhorn/last30days-skill` then `grok plugin install last30days` |\n`grok plugin update last30days` |\nCodex, Cursor, Copilot, Gemini CLI, or any of 50+\n|\n`npx skills add mvanhorn/last30days-skill -g` |\n`npx skills update last30days -g` |\nclaude.ai (web) |\n`last30days.skill` |\n\n**Claude Desktop**[Download the](https://github.com/mvanhorn/last30days-skill/releases/latest)and drag into Settings > Extensions`.mcpb`\n\nfor your platform**OpenClaw**`clawhub install last30days-official`\n\n`clawhub update last30days-official`\n\n```\n/plugin marketplace add mvanhorn/last30days-skill\n```\n\nRecommended because the Claude Code marketplace handles updates for you — the plugin cache is versioned and auto-refreshes when a new release publishes. Run `claude plugin update last30days@last30days-skill`\n\nto force a check.\n\nIf you'd rather use the agent-skills install path on Claude Code, that's also supported:\n\n```\nnpx skills add mvanhorn/last30days-skill -g -a claude-code\n```\n\nThe native plugin and the `npx skills`\n\ninstall can coexist. Note that Claude Code does not dedupe across install methods: if you have both the marketplace plugin and the `npx skills`\n\ncopy active, `/last30days`\n\nwill show two entries. Use one install method per machine.\n\n[Grok Build](https://docs.x.ai/build/features/skills-plugins-marketplaces) (`grok`\n\n) installs last30days as a native plugin. Direct install tracks the repository:\n\n```\ngrok plugin install mvanhorn/last30days-skill\n```\n\nOr add this repo as a marketplace source, then install by plugin name:\n\n```\ngrok plugin marketplace add mvanhorn/last30days-skill\ngrok plugin install last30days\n```\n\nAdd `--trust`\n\nto skip the install confirmation. Update with `grok plugin update last30days`\n\n. Grok also reads the Claude Code manifests for compatibility; the native `.grok-plugin/`\n\npair is the first-class lane (and what an official [xAI marketplace](https://github.com/xai-org/plugin-marketplace) listing points at). `npx skills add`\n\nremains a valid cross-host fallback.\n\nInstall via the open [Agent Skills](https://agentskills.io) CLI — supports 50+ harnesses including `codex`\n\n, `cursor`\n\n, `github-copilot`\n\n, `gemini-cli`\n\n, `claude-code`\n\n, `windsurf`\n\n, `cline`\n\n, `continue`\n\n, `roo`\n\n, `aider-desk`\n\n, `opencode`\n\n, `goose`\n\n, and more (full list on the [vercel-labs/skills repo](https://github.com/vercel-labs/skills)).\n\n```\nnpx skills add mvanhorn/last30days-skill -g\n```\n\nThe `-g`\n\n(global) flag installs to your user directory so the skill is available across all projects. Without `-g`\n\n, `npx skills`\n\ninstalls project-locally into `./.skills/`\n\n(committed with the repo). For a research-the-world tool, global is what you want.\n\nCodex desktop and other folder-mode hosts can work in ordinary folders as well as Git repos. Before first research, ask the host agent to run the bundled `scripts/last30days.py --preflight`\n\nfrom the loaded skill directory; in a source checkout, the equivalent command is `python3 skills/last30days/scripts/last30days.py --preflight`\n\n. It shows the config source, browser-cookie plan, planned writes, optional commands, and ignored project config without reading cookies, writing files, or running research.\n\nBy default this installs for whichever harness `npx skills`\n\ndetects. To target a specific one (or multiple):\n\n```\nnpx skills add mvanhorn/last30days-skill -g -a codex\nnpx skills add mvanhorn/last30days-skill -g -a cursor\nnpx skills add mvanhorn/last30days-skill -g -a gemini-cli\nnpx skills add mvanhorn/last30days-skill -g -a codex -a cursor\n```\n\nUpdate later with:\n\n```\nnpx skills update last30days -g\n```\n\nOr update everything you've installed globally via `npx skills`\n\n:\n\n```\nnpx skills update -g\n```\n\nList and remove with `npx skills list -g`\n\nand `npx skills remove last30days -g`\n\n.\n\n[Download](https://github.com/mvanhorn/last30days-skill/releases/latest/download/last30days.skill)from the latest release`last30days.skill`\n\n- Go to\n[claude.ai > Customize > Skills](https://claude.ai/customize/skills) - Click the\n`+`\n\nbutton in the Skills panel > click on`Create skill`\n\n>`Upload a skill`\n\nand browse/drop the file in\n\nEnable \"Code execution and file creation\" under Capabilities first — skills won't run without it.\n\nClaude Desktop installs `/last30days`\n\nas an MCP server via a `.mcpb`\n\nbundle (a one-click Model Context Protocol package).\n\n- Go to the\n[latest release](https://github.com/mvanhorn/last30days-skill/releases/latest)and download the`.mcpb`\n\nfor your platform:- macOS Apple Silicon:\n`last30days-pp-mcp-darwin-arm64.mcpb`\n\n- macOS Intel:\n`last30days-pp-mcp-darwin-amd64.mcpb`\n\n- Linux x86_64:\n`last30days-pp-mcp-linux-amd64.mcpb`\n\n- macOS Apple Silicon:\n- Open Claude Desktop, go to Settings > Extensions, and drag the file in.\n- When prompted, paste API keys for the sources you want to enable. Every field is optional — the engine degrades to web-only mode if you skip them all. Keys are stored in your OS keychain.\n- Restart Claude Desktop. Ask Claude to \"research Peter Steinberger\" or any topic and it will call the\n`research`\n\ntool.\n\n**Host requirement:** Python 3.12+ on PATH. The bundle ships the engine source but uses your local Python interpreter. Install from [python.org](https://www.python.org/downloads/) on Windows; macOS and most Linux distros ship a compatible version.\n\n**Keys don't sync with the Code skill.** Claude Desktop and Claude Code maintain separate credential stores by design. If you already configured `~/.config/last30days/.env`\n\nfor the Code skill, you'll re-enter the same keys here once.\n\nWindows support is deferred until per-platform manifest entry points are sorted out; track in a follow-up issue.\n\n```\nclawhub install last30days-official\n```\n\nFor X/Twitter action workflows outside `/last30days`\n\nresearch, such as posting\ntweets or replies, follower export, media handling, monitors, and giveaway\ndraws, use [TweetClaw](https://github.com/Xquik-dev/tweetclaw) as the companion\nOpenClaw plugin. TweetClaw is maintained by Xquik-dev and is listed only as an\noptional companion path, not a last30days dependency or endorsement.\n\n```\ngit clone https://github.com/mvanhorn/last30days-skill.git\nln -s \"$(pwd)/last30days-skill/skills/last30days\" ~/.claude/skills/last30days\n```\n\nThe symlink keeps the install in sync with your working tree as you edit — no re-copy needed. For `claude.ai`\n\n, build the `.skill`\n\nfile from source: `bash skills/last30days/scripts/build-skill.sh`\n\nproduces `dist/last30days.skill`\n\n.\n\nReddit (with comments), Hacker News, Polymarket, and GitHub work immediately. Zero configuration. Run `/last30days`\n\nonce and the setup wizard unlocks more sources in 30 seconds, including the free arXiv and Techmeme CLIs.\n\nThese platforms don't have relationships with each other. X doesn't know what Reddit thinks. YouTube doesn't see TikTok. But you can bring your own API keys and browser tokens, and suddenly you have access to all of them at once.\n\n| Sources | What you need | Cost |\n|---|---|---|\n| Reddit (with comments) + HN + Polymarket + GitHub + StockTwits | Nothing | Free |\n| arXiv + Techmeme | Free CLIs, auto-installed by first-run setup | Free |\n| X / Twitter | Log into x.com in any browser, or set `XQUIK_API_KEY` / `XAI_API_KEY` |\nBrowser cookies are free; keys are provider-specific |\n| YouTube | `brew install yt-dlp` |\nFree |\n| Bluesky | App password from bsky.app | Free |\n| TikTok + Instagram + Threads + Pinterest + LinkedIn + YouTube comments | ScrapeCreators key | 10,000 free calls, then PAYG |\n| Xiaohongshu (RED) | Run a logged-in x-mcp browser plugin or `xiaohongshu-mcp` service and opt in with `--search xhs` per run or `INCLUDE_SOURCES=xiaohongshu` in `.env` ; last30days auto-probes `http://localhost:18060` then `http://host.docker.internal:18060` , or use `XIAOHONGSHU_API_BASE` for a custom URL |\nNo last30days API key; depends on your local browser-session service |\n| DripStack (premium financial newsletters) | Opt-in: `--search dripstack` per run, or `INCLUDE_SOURCES=dripstack` in `.env` |\nNo key; free public search API |\n| Perplexity Sonar / Search API / Deep Research | Perplexity key, or OpenRouter key as Sonar fallback | Pay as you go |\n| Web search | Brave Search key | 2,000 free queries/month |\n\nOn macOS you can store keys in the system Keychain instead of a `.env`\n\nfile. The skill picks them up automatically as the lowest-priority source — `.env`\n\nfiles and process environment still win on collision.\n\n```\n# Interactive setup — prompts for each known key, skip with empty input\nskills/last30days/scripts/setup-keychain.sh\n\n# Or store a single key by hand\nsecurity add-generic-password -a \"$USER\" -s last30days-XAI_API_KEY -w \"xai-...\"\n\n# Inspect / clean up\nskills/last30days/scripts/setup-keychain.sh --list\nskills/last30days/scripts/setup-keychain.sh --delete XAI_API_KEY\n```\n\nItems are stored under service name `last30days-<KEY>`\n\nfor the current user. On non-Darwin platforms the loader is a no-op, so there is no behaviour change for Linux/Windows users.\n\nAlready have keys under different Keychain service names? Set the non-secret `LAST30DAYS_KEYCHAIN_ALIASES`\n\nmapping described in [CONFIGURATION.md](/mvanhorn/last30days-skill/blob/main/CONFIGURATION.md#reusing-existing-macos-keychain-items) instead of copying secrets.\n\nSee [CONFIGURATION.md](/mvanhorn/last30days-skill/blob/main/CONFIGURATION.md) for the full per-source key matrix, reasoning provider priority, and web-search backend priority.\n\nTwo things you'll likely want to know on day one:\n\n**Where research files are saved.** `LAST30DAYS_MEMORY_DIR`\n\ndefaults to `~/Documents/Last30Days/`\n\n(Windows: `C:\\Users\\<you>\\Documents\\Last30Days\\`\n\n). Override by setting that env var to any path in your shell, or `--save-dir <path>`\n\nper run. Use `--output <file>`\n\nwhen you need the rendered result at an exact path, using the format selected by `--emit`\n\n. Use `--save-suffix=<name>`\n\nto keep multiple variations of the same topic separate (e.g. per client). Each `--save-dir`\n\nrun produces `<slug>-raw[-suffix].md`\n\n. Run `python3 skills/last30days/scripts/last30days.py --preflight`\n\nto review planned writes before a research run.\n\n**Structured output for agents and workflows.** Ask `/last30days`\n\nfor machine-readable JSON to receive the stable, versioned agent profile. For direct engine use in scripts or development, run `python3 skills/last30days/scripts/last30days.py \"AI coding agents\" --emit=json`\n\n; add `--json-profile=raw`\n\nonly when you need the unversioned internal `Report`\n\ndump. See the [JSON export field reference and versioning policy](/mvanhorn/last30days-skill/blob/main/docs/reference/json-export.md).\n\n**Topic-less discovery.** Ask `/last30days what's trending in AI agents?`\n\nto get a ranked discovery brief instead of researching a topic you already know - on an agent host this runs the three-command host-judged protocol (the model names topics, filters junk, scores worthiness, and writes the content angles). For direct engine use in scripts or cron, run `python3 skills/last30days/scripts/last30days.py --discover \"AI agents\"`\n\n(one-shot: deterministic topic names, no angles); add `--emit=json`\n\nfor the versioned discovery contract. Discovery is mutually exclusive with a positional topic and `--drill`\n\n.\n\n**Trend monitoring across runs.** The default mode produces a fresh markdown snapshot per run. To accumulate findings over time, add `--store`\n\nto persist into a SQLite database, then use [ scripts/watchlist.py](/mvanhorn/last30days-skill/blob/main/skills/last30days/scripts/watchlist.py) for scheduled runs (with optional Slack / webhook delivery on new findings) and\n\n[for daily / weekly digests. The full cadence pattern is in](/mvanhorn/last30days-skill/blob/main/skills/last30days/scripts/briefing.py)\n\n`scripts/briefing.py`\n\n[CONFIGURATION.md](/mvanhorn/last30days-skill/blob/main/CONFIGURATION.md#trend-monitoring-store--watchlist--briefings).\n\n**A subscribable research library.** Ask `/last30days`\n\nto build your library feed, or use `python3 skills/last30days/scripts/last30days.py library feed`\n\ndirectly for scripting and development. It turns saved briefs into `index.html`\n\n, a local Atom `feed.xml`\n\n, and readable brief pages. Add `--publish`\n\nonly when you want the HTML index and brief pages hosted; publishing is explicit opt-in and public by default. To make the Atom feed subscribable, host the generated output directory on a static host such as GitHub Pages.\n\n**Search everything you've researched.** Ask `/last30days search my library for MCP servers`\n\nor `/last30days have I researched MCP servers before?`\n\n. For direct engine use, run `python3 skills/last30days/scripts/last30days.py library search \"MCP servers\"`\n\n. Search is offline and deterministic: it incrementally indexes the same saved briefs used by the library feed, merges matching per-run store sightings, and groups results by topic and date. Fresh runs also surface a compact **From your library** section when prior research overlaps the current topic; set `LAST30DAYS_LIBRARY_CONTEXT=off`\n\nto disable that passive context.\n\nPer-client wrapper scripts, custom category-peer subreddits, and the experimental beta channel for in-progress customizations are also documented in [CONFIGURATION.md](/mvanhorn/last30days-skill/blob/main/CONFIGURATION.md).\n\nPublished a recurring AI update, market watch, or wonderfully narrow obsession with last30days? Share the public library URL—or the Atom URL after hosting `feed.xml`\n\non a static host—in [the community showcase thread](https://github.com/mvanhorn/last30days-skill/issues/532). Community feeds will be linked here as their owners submit them; the thread is the collection point in the meantime.\n\n**You type a topic.** Person, company, product, technology, \"X vs Y.\" Anything.**The agent resolves who matters.** Finds X handles (including founders), GitHub repos, subreddits, TikTok hashtags, YouTube channels. For \"Kanye West\" it knows r/hiphopheads, @kanyewest, and \"bully review\" on YouTube. For \"OpenClaw\" it resolves openclaw/openclaw on GitHub and fetches live star counts.**All sources searched in parallel.** Multi-query expansion. Results scored by engagement, relevance, freshness.**The depth nobody else has.** Full YouTube transcripts from reaction videos. Top Reddit comments with upvote counts. TikTok captions. Polymarket odds. Not just titles and links.**Same story, merged.** Wireless Festival announced on Reddit, discussed on X, ticket prices on TikTok = one cluster, not three separate items.**Synthesized into one brief.** Grounded in specific data. Cited by source. Ranked by what people actually engage with. Not \"here's what I found.\" It's \"here's what matters.\"**Then it becomes your expert.** After one run, your Claude session knows everything the community knows. Ask follow-up questions. Have it write prompts, draft emails, plan trips, architect systems - all grounded in what's real right now.\n\n\"I found a Claude Code skill that researches any topic across Reddit, X, YouTube, and HN from the last 30 days. Then writes the prompts for you. I've been manually searching Reddit and X for research before every piece of content I write. Tab by tab. Thread by thread. That's the part that takes 90 minutes. This eliminates it.\" -@itsjasonai\n\n\"This one skill replaced my entire research workflow. You give it a topic, it scrapes Reddit, X, and the web for what people are actually talking about. Not old blog posts. Real conversations from the last 30 days.\" -@itswilsoncharles\n\n\"5 of the 10 trending repos on GitHub today are Claude tools. #1: mvanhorn/last30days-skill\" -@yieldhunter95\n\nMIT license.
