Trend Hunter — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the trendhunter-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install trendhunter --cli-only
   

2. Verify: trendhunter-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer):

go install github.com/mvanhorn/printing-press-library/library/marketing/trendhunter/cmd/trendhunter-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

When to Use This CLI

Use this CLI when you want TrendHunter data inside an agent loop, a script, or a daily routine - rather than clicking the site by hand. It's strongest for week-over-week trend monitoring, FAQ-style trend summaries an LLM can quote, and corpus-wide keyword clustering. It's a free, no-auth scraper; for the official paid API surface, use TrendHunter's commercial offering instead.

When Not to Use This CLI

Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Local state that compounds

• digest — Generate a week-over-week digest of new vs repeat trends in a category with top rising keywords.

  Agents pulling a weekly competitive scan can ask 'what's new in eco this week' without re-clicking 30 cards by hand.

  trendhunter-pp-cli digest --since 7d --category eco --json
  

• watch — Per-category new-only feed - fills the gap that TrendHunter's RSS is global-only.

  Agents and indie scouts get a clean delta for one vertical without re-processing the global firehose.

  trendhunter-pp-cli watch --category gadgets --since 24h --json
  

• cluster — Surface rising keyword clusters via FTS5 co-occurrence with a rising-vs-prior-window delta.

  Agents researching an emerging theme see which adjacent keywords are accelerating, not just the headline trends.

  trendhunter-pp-cli cluster --window 30d --min-count 3 --json
  

• authors — Rank TrendHunter authors and futurists by time-windowed publish rate, not lifetime count.

  Find which trend hunters are currently active in your space, not just who has the biggest historical footprint.

  trendhunter-pp-cli authors --top 20 --since 30d --json
  

• inbox — Show trends seen since the last invocation of inbox - a per-machine cursor table.

  Build it into a Monday-morning routine and only ever see things you haven't seen before.

  trendhunter-pp-cli inbox --json
  

Agent-native extraction

• faq — Extract the FAQPage JSON-LD from a trend page into structured Q&A.

  Agents get a ready-to-quote Q&A summary of each trend without prompting another LLM to summarize the article.

  trendhunter-pp-cli faq ai-clone --json
  

• brief — One-shot agent brief: top-N ranked trends in a category, each with FAQ Q&A and keywords, rendered as JSON or markdown.

  Plugs straight into an agent prompt as ground truth for a market memo, no glue code needed.

  trendhunter-pp-cli brief --category ai --top 10 --format markdown
  

• scout — Pull top trends in a category, score each by relevance to a business profile, optionally route the scoring through a local LLM.

  Agents researching a vertical get a ranked, business-scoped trend list ready to pipe into the next stage of their pipeline.

  trendhunter-pp-cli scout --category kitchen --business "We sell smart ovens for home cooks" --top 10 --llm
  

Graph and synthesis

• megatrend-map — Walk the related-trend graph two levels deep from a starting slug, returning depth-1 and depth-2 related slugs so you can see which free trends cluster around a given concept.

  Evaluators deciding whether a paid megatrend report is worth $295 can see which free trends ladder up to it.

  trendhunter-pp-cli megatrend-map ai-clone --json
  

Discovery Signals

This CLI was generated with browser-observed traffic context.

• Capture coverage: 11 API entries from 30 total network entries
• Protocols: html (100% confidence), rss (100% confidence)
• Generation hints: Use stdlib HTTP transport (http_transport: standard)., Default UA must imitate Chrome - curl default UA is blocked., Default Accept header must be Chrome-style 'text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8' - bare '/' is blocked., RSS feed is global only. Per-category RSS returns valid-but-empty channels; do not call them., Trend pages occasionally redirect to vertical microsites (cleanthesky.com, etc.). Follow redirects; record the canonical /trends/ URL., FAQPage JSON-LD on /trends/ is the highest-density agent-summary surface; extract with the faq command., No clearance cookie, no Surf, no browser sidecar.

Command Reference

category — Category index pages (tech, fashion, food, eco, ai, marketing, design, ...)

• trendhunter-pp-cli category <category> — Fetch a TrendHunter category index page (~30 trend cards). The CLI's 'category ' command parses this.

• trendhunter-pp-cli megatrends — Fetch the megatrend index page.

popular — Curated 'popular right now' index.

• trendhunter-pp-cli popular — Fetch the popular-trends index page (~30 cards). Run 'popular' to get parsed JSON.

reports — Trend report index.

• trendhunter-pp-cli reports — Fetch the trend-reports landing page (titles, descriptions, paid PDF links).

results — Site search-results endpoint (the framework already provides a hand-built search command; this exposes the raw HTML page).

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

trendhunter-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Weekly trend memo for eco

trendhunter-pp-cli digest --since 7d --category eco --json --select trends.title,trends.keywords,trends.first_seen

Returns just the title, keywords, and first-seen timestamp for every new eco trend in the past week. Narrow surface; great for a slack post or LLM prompt.

Agent brief for AI

trendhunter-pp-cli brief --category ai --top 10 --format markdown

Top 10 AI trends, each with FAQ Q&A and keywords, rendered as markdown ready to paste into a prompt.

Rising-keyword scan

trendhunter-pp-cli cluster --window 30d --min-count 3 --json

Surfaces keywords whose co-occurrence count rose vs the prior 30-day window.

Active futurists this month

trendhunter-pp-cli authors --top 20 --since 30d --json

Time-windowed publish velocity for trend hunters and futurists - the site's /scoreboard is lifetime-only.

Map a megatrend to free trends

trendhunter-pp-cli megatrend-map ai-clone --json

Walks the related-trend graph two levels deep from the starting slug, surfacing the depth-1 and depth-2 related slugs around the concept.

Auth Setup

No authentication required.

Run trendhunter-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  trendhunter-pp-cli category mock-value --agent --select id,name,status
  

• Previewable — --dry-run shows the request without sending

• Offline-friendly — sync/search commands can use the local SQLite store when available

• Non-interactive — never prompts, every input is a flag

• Read-only — do not use this CLI for create, update, delete, publish, comment, upvote, invite, order, send, or other mutating requests

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

trendhunter-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
trendhunter-pp-cli feedback --stdin < notes.txt
trendhunter-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.trendhunter-pp-cli/feedback.jsonl. They are never POSTed unless TRENDHUNTER_FEEDBACK_ENDPOINT is set AND either --send is passed or TRENDHUNTER_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

trendhunter-pp-cli profile save briefing --json
trendhunter-pp-cli --profile briefing category mock-value
trendhunter-pp-cli profile list --json
trendhunter-pp-cli profile show briefing
trendhunter-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
