HackerNews Daily Digest
A minimal news-aggregation project that fetches HackerNews top stories once a day, filters them by score and (optional) topic keywords, and keeps a rolling markdown log + a live Scarf dashboard.
Requires Scarf 2.3+ — uses the Configuration form during install and on-demand re-edit.
What you get
- Configurable score threshold — only stories at or above this score show up. HN front page averages ~150; lower it to widen the net, raise it to focus on the truly viral.
- Configurable item cap — keeps each digest from sprawling. Default 15.
- Optional topic keywords — a list of keywords (case-insensitive substring match against titles). Items that match a keyword get a
[topic]tag in the digest and"ok"status in the dashboard list. Empty list = include every story above threshold, no highlighting. - No API keys — HackerNews' Firebase API is fully public. Nothing in this project's
.scarf/config.jsonis secret; no Keychain entries are created. digest.md— agent's append-only log. New runs prepend at the top. Created automatically on first run..scarf/dashboard.json— live dashboard with stat widgets (top score, items tracked, last run) and a Top Stories list.- Cron job
Daily HN digest— registered (paused) by the installer; tag[tmpl:awizemann/hackernews-digest]. Runs daily at 8:00 AM when enabled.
First steps
- During install, fill in the Configuration form — set
min_score,max_items, and any topic keywords you care about. (All have sensible defaults if you just want to skip it.) Hit Continue, then Install. - After install, open the Cron sidebar and enable the
[tmpl:awizemann/hackernews-digest] Daily HN digestjob. It's paused on install so nothing runs without your explicit say-so. - From the project's dashboard, ask your agent to run the job now: "Run the HN digest and update the dashboard."
- Future runs happen automatically at 8 AM daily.
Changing filters later
Click the Configuration button (slider icon, dashboard toolbar) to re-open the form pre-filled with your current values. Adjust score, max items, or topics. Save. The next cron run picks up the changes.
Customizing
- Change the schedule. Edit the cron job in the Cron sidebar — accepts
30m,every 2h, or standard cron expressions like0 8 * * *. - Switch sources. This template is HN-only by design. To pull from Lobsters, Reddit, or RSS, fork it (export from a Scarf project, edit
cron/jobs.json's prompt, re-import) — most of the agent contract is generic. - Add alerting. Set a
delivertarget on the cron job (Discord, Slack, Telegram) — the agent will post the run summary there instead of just writing todigest.md.
Recommended model
claude-haiku-4 works well — this is a simple HTTP-fetch + filter + markdown task. Haiku keeps costs low when the cron runs daily. The recommendation appears in the Configuration form; Scarf doesn't auto-switch your active model, so adjust via Settings if you'd like.
Uninstalling
Right-click the project in the sidebar → Uninstall Template… (or click the shippingbox icon on the dashboard header). Scarf walks you through exactly what's about to be removed: template-installed files in the project dir, the [tmpl:…] cron job, and the configuration values you entered (config.json; this template stores no secrets so there's nothing in Keychain to clean up). User-created files (like digest.md) are preserved.
