Previewing Install & Setup.

Prompt PreviewInstall & Setup

Install the skill "Deadlinks" (rogue-agent1/deadlinks) from ClawHub.
Skill page: https://clawhub.ai/rogue-agent1/deadlinks
Keep the work scoped to this skill only.
After install, inspect the skill metadata and help me finish setup.
Use only the metadata you can verify from ClawHub; do not invent missing requirements.
Ask before making any broader environment changes.

Purpose & Capability

Name/description match the included Python scripts: the tool extracts Markdown/HTML links, checks local file paths and HTTP(s) URLs, and offers crawling and concurrency. The required resources (none) are proportional to the stated functionality.

ℹ

Instruction Scope

SKILL.md instructs running the provided script(s) against files or URLs, which is consistent. Be aware the tool will: perform outbound HTTP(S) requests to any URLs you ask it to check (including internal hosts reachable from the runtime), and will test existence of local file paths referenced by links (including absolute paths). These behaviors are expected for a link checker but can reveal network reachability or file existence when run in sensitive environments.

✓

Install Mechanism

No install spec or remote downloads; code is included as plain Python files and runs with system Python (no external packages). This is low-risk from an install perspective.

✓

Credentials

The skill declares no environment variables, credentials, or special config paths and the code does not read environment secrets. No disproportionate credential access is requested.

✓

Persistence & Privilege

The skill does not request permanent presence (always=false) and does not modify agent/system configuration. It runs only when invoked.

Assessment

This appears to be a straightforward broken-link checker. Before running it, note that it will make outbound HTTP requests to any URLs you ask it to scan (so it can reach internal services if the runtime has network access) and will check existence of local file paths referenced in documents (including absolute paths). If you plan to scan untrusted content or run in a sensitive environment, run the script in an isolated environment or restrict network access. Also be aware of a minor bug in the code (an unconditional 'or True' that forces broken-link printing) — not a security issue but worth fixing if you want cleaner output.

Like a lobster shell, security has layers — review code before you run it.
