pp-qurankuEvery Al-Qur'an feature the app has, plus the Indonesian Tarjamah Tafsiriyah offline, a local database, offline search, a khatam plan, and a hifz tracker no other Qur'an tool has.
Pp Quranku is an agent skill from mvanhorn/printing-press-library. Every Al-Qur'an feature the app has, plus the Indonesian Tarjamah Tafsiriyah offline, a local database, offline search, a khatam plan, and a hifz tracker no other Qur'an tool has. Trigger phrases: read surah, tarjamah tafsiriyah, cari ayat, verse of the day, khatam plan, use quranku, run quranku.
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit d9a1696. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadBashFrom allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
goclaudenpxFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Pp Quranku loads about 3.4k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 1,465 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, BashAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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/education/quranku/cmd/quranku-pp-cli@latestIf --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.
QuranKu carries Ustadz Muhammad Thalib's Tarjamah Tafsiriyah translation alongside Quran.com's metadata and audio, all in a local SQLite store. Read any surah, look up any verse, search offline with find, follow a plan to finish the Qur'an, and track memorization with hifz.
Use QuranKu when an agent or user needs Qur'an text with the Indonesian Tarjamah Tafsiriyah, offline verse search, precise ayah lookups, or personal reading/memorization tracking. It is the only tool that carries this specific translation with a local database.
Do not use this CLI for:
These capabilities aren't available in any other tool for this API.
find — Search the Qur'an offline by word or meaning across Arabic and the Indonesian Tafsiriyah.
Reach for this when you need to locate verses by meaning without a live search API.
quranku-pp-cli find "kasih sayang" --jsonverse — Get a single verse (e.g. 2:255) with Arabic and the Tafsiriyah translation joined together.
Use for a precise ayah lookup instead of fetching a whole surah.
quranku-pp-cli verse 2:255 --jsondaily — A stable, date-seeded verse of the day with its Tafsiriyah translation.
Use for a reproducible daily reflection verse.
quranku-pp-cli daily --jsonrandom — A random verse with its Tafsiriyah translation for reflection.
Use for a spontaneous verse for study or reflection.
quranku-pp-cli random --jsonplan — Build and follow a plan to finish the Qur'an in N days, tracking progress locally.
Use to pace and track a full Qur'an reading over time.
quranku-pp-cli plan start --days 30hifz — Mark and review Qur'an memorization progress per surah or verse.
Use to track what you have memorized across sessions.
quranku-pp-cli hifz mark 1 --jsonbookmark — Save verses with personal notes for later, offline.
Use to keep a personal, portable set of saved verses.

quranku-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.
quranku-pp-cli surah get 36 --json --select data.verses.translations.terjemahTafsiriyahFetch Yasin and narrow the payload to just the Tafsiriyah translation lines.
quranku-pp-cli find "sabar" --jsonFind verses mentioning patience across the local Arabic + Tafsiriyah index.
quranku-pp-cli plan start --days 30Create a reading plan that finishes the Qur'an in 30 days and tracks progress.
No authentication required.
Run quranku-pp-cli doctor to verify setup.
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:
quranku-pp-cli chapters list --agent --select id,name,statusPreviewable — --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
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.
Agents should treat the CLI's path resolver as part of the runtime contract:
Use --home <dir> for one invocation, or set QURANKU_HOME=<dir> to relocate all four path kinds under one root.
Use per-kind env vars only when a specific kind must diverge: QURANKU_CONFIG_DIR, QURANKU_DATA_DIR, QURANKU_STATE_DIR, QURANKU_CACHE_DIR.
Resolution order is per-kind env var, --home, QURANKU_HOME, XDG (XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME), then platform defaults.
config contains settings like config.toml and profiles. data contains credentials.toml, data.db, cookies, and auth sidecars. state contains persisted queries, jobs, and teach.log. cache contains regenerable HTTP/cache files.
Stored secrets live in credentials.toml under the data dir. Existing legacy config.toml secrets are read for compatibility and leave config.toml on the first auth write.
Run quranku-pp-cli doctor --fail-on warn to surface path and credential-location warnings. agent-context exposes a schema v4 paths block for agents that need the resolved dirs.
For MCP, pass relocation through the MCP host config. The MCP binary does not inherit CLI flags:
{
"mcpServers": {
"quranku": {
"command": "quranku-pp-mcp",
"env": {
"QURANKU_HOME": "/srv/quranku"
}
}
}
}Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use QURANKU_HOME or per-kind vars as durable fleet levers, and use --home only for a single invocation. Relocation is not reversible by unsetting env vars; move files manually before clearing QURANKU_HOME, or doctor will not find credentials left under the former root.
When you (or the agent) notice something off about this CLI, record it:
quranku-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
quranku-pp-cli feedback --stdin < notes.txt
quranku-pp-cli feedback list --json --limit 10Entries are stored locally as feedback.jsonl under the resolved data dir. They are never POSTed unless QURANKU_FEEDBACK_ENDPOINT is set AND either --send is passed or QURANKU_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.
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.
A profile is a saved set of flag values, reused across invocations. Use it when a scheduled or recurring agent reuses the same saved flags while providing different input each run.
quranku-pp-cli profile save briefing --json
quranku-pp-cli --profile briefing chapters list
quranku-pp-cli profile list --json
quranku-pp-cli profile show briefing
quranku-pp-cli profile delete briefing --yesExplicit 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.

Every Al-Qur'an feature the app has, plus the Indonesian Tarjamah Tafsiriyah offline, a local database, offline search, a khatam plan, and a hifz tracker no other Qur'an tool has. Pp Quranku is an agent skill from mvanhorn/printing-press-library. Every Al-Qur'an feature the app has, plus the Indonesian Tarjamah Tafsiriyah offline, a local database, offline search, a khatam plan, and a hifz tracker no other Qur'an tool has.
Pp Quranku fits situations like: phrases: read surah; tarjamah tafsiriyah; verse of the day.
Run `npx skills add mvanhorn/printing-press-library --skill pp-quranku -a claude-code`. Or copy the skill folder (cli-skills/pp-quranku in mvanhorn/printing-press-library) into .claude/skills/pp-quranku in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mvanhorn/printing-press-library --skill pp-quranku -a codex`. Or copy the skill folder (cli-skills/pp-quranku in mvanhorn/printing-press-library) into .agents/skills/pp-quranku in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mvanhorn/printing-press-library --skill pp-quranku -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pp-quranku, .gemini/skills/pp-quranku, .github/skills/pp-quranku and .opencode/skills/pp-quranku in your project.
Going by SKILL.md and its folder, Pp Quranku needs the command-line tools its instructions call (go, claude and npx). Our summary lists: Node.js. Its frontmatter pre-approves these tools: Read, Bash.
SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Pp Quranku is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 3.4k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
