What you can build

  • Read an account CSV, investigate each named company, and write one cited meeting-preparation Markdown brief per row.
  • Transform a discovery brief and its topic angles into draft calendar rows with topic, proposed angle, and a human review status.
  • Read the documented doctor JSON output and turn configured-source failures into a concise internal repair queue.
  • Take a question and saved-library search results, then assemble dated matches into a topic-grouped packet for a team review.
  • Combine a current hiring-signals report with a manually maintained prior-roles CSV to produce a role-by-role novelty and focus-change memo.

Try this prompt

Build a small local account-research runner using the documented last30days skill. Accept a CSV with one company or person per row, invoke a separate recent-topic investigation for each, and create one Markdown meeting brief per input row with the returned findings and citations. Keep the original CSV and research artifacts unchanged; write generated briefs to a separate output folder. Report failed or incomplete runs rather than inventing missing findings. Include a short README explaining setup, inputs, outputs, and source-access limits.

Get started

  1. Install the skill

    Use the documented Agent Skills installer for a supported host, or the Claude Code marketplace route. The reusable skill is at skills/last30days/SKILL.md.

  2. Check the runtime

    The engine requires Python 3.12+ and Node.js. The README also documents yt-dlp and optional source CLIs for additional research coverage.

  3. Select sources and credentials

    Reddit, Hacker News, Polymarket, and GitHub work without source setup. Optional credentials belong in ~/.config/last30days/.env; browser-cookie access requires consent.

License & notes

MITMIT-licensed; commercial use is allowed with the license notice retained. The skill itself does not set a price. A compatible AI agent host may involve model or runtime charges; optional search and data APIs, X access, and hosted publishing may incur provider fees. No dollar amounts are asserted. Research files are saved locally by default; publishing is opt-in.

  • Requires a compatible AI agent host, Python 3.12+, and Node.js; optional sources may need local tools or credentials.
  • Source availability and depth depend on platform access, authentication, and configured APIs; a run may have partial coverage.
  • Designed for recent topic research, not exhaustive archival search or guaranteed verification of every reported claim.
  • Optional model, API, and hosting use may incur provider charges. MIT commercial use requires retaining the license notice.
