Description
Search Z-Library and send EPUBs to Kindle
README (SKILL.md)
Run the book2kindle CLI to search Z-Library and send EPUBs to Kindle.
Execute: .venv/bin/book2kindle $ARGUMENTS
Behavior
- If
$ARGUMENTSis empty, run.venv/bin/book2kindle --helpand present the available commands. - For
search \x3Ctitle>: run.venv/bin/book2kindle search "\x3Ctitle>"and display the results as a numbered list. - For
send \x3Ctitle> --pick N: run.venv/bin/book2kindle send "\x3Ctitle>" --pick Ndirectly. - For
send \x3Ctitle>without--pick: first run.venv/bin/book2kindle search "\x3Ctitle>"to show results, then ask the user which one to send. Once they choose, run.venv/bin/book2kindle send "\x3Ctitle>" --pick N. - Pass through any other flags the user provides (e.g.
--pick,--limit).
Output
Present CLI output conversationally. Summarize results clearly — show book title, author, format, and file size when available.
Usage Guidance
This skill is instruction-only but expects you to have a local CLI at .venv/bin/book2kindle; the registry entry doesn't provide or install that tool. Before using it: (1) verify where the book2kindle CLI comes from — inspect its source code or install it from a trusted, auditable repository (e.g., a known GitHub release). (2) Confirm how the CLI handles your Kindle account (email, credentials) and do not provide secrets unless you trust the CLI and its install source. (3) Be aware that Z‑Library is widely associated with infringing/pirated content — using tools that automate downloading from it can carry legal and policy risks. (4) If you proceed, run the CLI manually first to see exactly what network calls and files it uses; avoid granting broad credentials or installing untrusted binaries. If the skill included an install URL, a link to the CLI repo, or declared the env vars it needs, that would increase confidence.
Capability Analysis
Type: OpenClaw Skill
Name: book2kindle
Version: 0.1.0
The skill is a straightforward command-line interface wrapper designed to search Z-Library and send EPUB files to Kindle via a local binary (`.venv/bin/book2kindle`). The instructions in SKILL.md correctly map user intent to specific CLI arguments and do not contain any evidence of malicious intent, data exfiltration, or prompt injection attacks.
Capability Assessment
Purpose & Capability
The skill claims to search Z‑Library and send EPUBs to Kindle but does not declare any required binaries, installs, or credentials. The SKILL.md requires executing .venv/bin/book2kindle, yet the registry metadata lists no required binary or install step — a clear mismatch. Additionally, sending to Kindle likely requires account configuration (email/address or credentials) which the skill does not mention or request.
Instruction Scope
The runtime instructions tell the agent to run a local CLI that will contact external services (Z‑Library and whatever mechanism sends to Kindle). The SKILL.md gives no guidance on what that CLI is, where it came from, or what data it will read, store, or transmit. It also permits arbitrary flags to be passed through, giving broad runtime discretion without constraints.
Install Mechanism
There is no install spec (instruction-only), which is low risk in general, but SKILL.md assumes the presence of a .venv/bin/book2kindle binary. That missing install/instruction to obtain the CLI is an incoherence: either the binary must be provided/installed or the skill will fail. Because the binary's provenance is unspecified, you cannot assess what code will run when invoked.
Credentials
requires.env lists nothing, but the functionality (sending books to a Kindle) typically requires account configuration or credentials (Send-to-Kindle email, OAuth, or SMTP/AMAZON API credentials). The skill gives no indication of how those credentials are provided or protected. Also, interacting with Z‑Library implicates content-distribution/legal risk that is not surfaced.
Persistence & Privilege
The skill is not marked always:true and model invocation is disabled (disable-model-invocation: true), so it cannot run autonomously. That limits the blast radius and is appropriate given the network/credential concerns.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install book2kindle - After installation, invoke the skill by name or use
/book2kindle - Provide required inputs per the skill's parameter spec and get structured output
