You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 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 kdpnichefinder --cli-only Verify: kdpnichefinder-pp-cli --version 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 1.26.5 or newer). This installs into $GOPATH/bin (default $HOME/go/bin ), so add that directory to $PATH instead: go install github.com/mvanhorn/printing-press-library/library/marketing/kdpnichefinder/cmd/kdpnichefinder-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. KDP Niche Finder is a click-to-browse web tool that shows one curated niche bucket at a time with no history and no export. This CLI mirrors all four buckets into local SQLite so you can rank niches by opportunity across buckets (rank), see which niches are rising or fading since your last refresh (drift), spot books that appear in multiple buckets (dupes), gauge publisher saturation, and export KDP-ready CSVs — all offline and agent-native. When to Use This CLI Use this CLI when an agent or power user needs to research Amazon KDP niches programmatically: ranking opportunities across all buckets, tracking niche revenue trends over time, studying publisher competition, or exporting shortlists. It turns KDP Niche Finder's browse-only web UI into a queryable local database. Anti-triggers Do not use this CLI for: Do not use this CLI to generate book covers or interiors — that is Artistly's generation suite, not this niche tool. Do not use it for live Amazon BSR lookups of arbitrary ASINs — it only covers the curated KDP Niche Finder buckets. Do not use it for non-US marketplaces — the source data is US-centric. Unique Capabilities These capabilities aren't available in any other tool for this API. Local state that compounds rank — Rank niches across all four buckets at once by a composite of estimated revenue, sales, and price. Pick this when an agent needs the single best niche by opportunity, not a bucket-by-bucket browse. kdpnichefinder-pp-cli rank --max-price 9.99 -- sort value --agent drift — Show which synced niches are rising or fading in estimated revenue versus an earlier snapshot. Pick this for timing decisions (publish now vs skip) that the source tool cannot answer at all. kdpnichefinder-pp-cli drift --since 7d -- sort rising --agent keywords — Tokenize synced book titles and count keyword frequency to surface hot terms for a niche. Pick this to seed KDP backend keyword fields from what is actually selling. kdpnichefinder-pp-cli keywords -- type evergreen --min-count 3 --agent Cross-bucket analysis dupes — Find books that appear in more than one niche bucket (same ASIN) and show which buckets. Pick this to spot niches surfacing in multiple buckets, a strong cross-validated signal. kdpnichefinder-pp-cli dupes --agent saturation — Per bucket, show how concentrated estimated revenue is among publishers (whale vs fragmented). Pick this to tell an open niche from one a single publisher already dominates. kdpnichefinder-pp-cli saturation -- type hidden_gems --agent competitors — For a focus book, list same-publisher and same-price-band competitors using the extracted ASIN. Pick this to study who else is winning a specific niche before committing to it. kdpnichefinder-pp-cli competitors 2584 --agent Agent-native plumbing export — Export title, ASIN, price, estimated sales, and revenue as CSV for KDP backend keyword and cover work. Pick this to hand a shortlist off to keyword/cover tooling without retyping titles. kdpnichefinder-pp-cli export --csv Discovery Signals This CLI was generated with browser-observed traffic context.

Command Reference books — Save and unsave niche books kdpnichefinder-pp-cli books <book_id> — Toggle save/unsave a book; optionally into a folder categories — Niche bucket metadata kdpnichefinder-pp-cli categories — List niche bucket categories (key, name, description) folders — Organize saved niches into folders kdpnichefinder-pp-cli folders create — Create a folder kdpnichefinder-pp-cli folders list — List your folders niches — Browse curated KDP niche buckets (real Amazon books with estimated sales/revenue) kdpnichefinder-pp-cli niches <type> — Browse a niche bucket: evergreen, fresh_money, hidden_gems, or high_ticket saved — Your saved niche books kdpnichefinder-pp-cli saved — List your saved books user — Authenticated account kdpnichefinder-pp-cli user — Show the authenticated user Finding the right command When you know what you want to do but not which command does it, ask the CLI directly: kdpnichefinder-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 Best low-price niche across all buckets kdpnichefinder-pp-cli rank --max-price 9.99 -- sort value --agent Ranks every synced book by revenue-per-dollar so cheap, high-return niches surface first. Narrow a verbose niche list to the fields that matter kdpnichefinder-pp-cli niches hidden_gems --search journal --agent -- select title,estimated_monthly_revenue,amazon_url Uses dotted --select paths to pull just title, revenue, and Amazon link from the paginated bucket response. Spot rising niches week over week kdpnichefinder-pp-cli drift --since 7d -- sort rising --agent Diffs the latest snapshot against one a week ago to show niches gaining estimated revenue. Export a saved shortlist for keyword work kdpnichefinder-pp-cli export --csv Emits title/ASIN/price/sales/revenue as CSV for KDP backend keyword and cover tooling. Auth Setup KDP Niche Finder uses a Laravel session login (no API key). Run kdpnichefinder-pp-cli auth login --chrome to capture your logged-in kdpnichefinder.com browser session; reads use the session cookie and saves/folders additionally send the CSRF token the CLI composes for you. Run kdpnichefinder-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: kdpnichefinder-pp-cli categories --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 Explicit retries — use --idempotent only when an already-existing create should count as success 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 AND no machine-format flag ( --json , --csv , --compact , --quiet , --plain , --select ) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout. Agent Feedback When you (or the agent) notice something off about this CLI, record it: kdpnichefinder-pp-cli feedback "the --since flag is inclusive but docs say exclusive" kdpnichefinder-pp-cli feedback --stdin < notes.txt kdpnichefinder-pp-cli feedback list --json --limit 10 Entries are stored locally at ~/.local/share/kdpnichefinder-pp-cli/feedback.jsonl . They are never POSTed unless KDPNICHEFINDER_FEEDBACK_ENDPOINT is set AND either --send is passed or KDPNICHEFINDER_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: Sink Effect stdout Default; write to stdout only file:<path> Atomically write output to <path> (tmp + rename) webhook:<url> POST the output body to the URL ( application/json or application/x-ndjson when --compact ) 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. kdpnichefinder-pp-cli profile save briefing --json kdpnichefinder-pp-cli --profile briefing categories kdpnichefinder-pp-cli profile list --json kdpnichefinder-pp-cli profile show briefing kdpnichefinder-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. Exit Codes Code Meaning 0 Success 2 Usage error (wrong arguments) 3 Resource not found 4 Authentication required 5 API error (upstream issue) 7 Rate limited (wait and retry) 10 Config error Argument Parsing Parse $ARGUMENTS : Empty, help , or --help → show kdpnichefinder-pp-cli --help output Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above Anything else → Direct Use (execute as CLI command with --agent ) MCP Server Installation Install the MCP server: go install github.com/mvanhorn/printing-press-library/library/marketing/kdpnichefinder/cmd/kdpnichefinder-pp-mcp@latest Register with Claude Code: claude mcp add kdpnichefinder-pp-mcp -- kdpnichefinder-pp-mcp Verify: claude mcp list Direct Use Check if installed: which kdpnichefinder-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
