Description
Campaign link builder and pre-launch validator for AI agents. Build UTM-tracked links, validate destinations, and inspect landing pages for social sharing re...
Usage Guidance
This skill appears coherent and implements what it says: a CLI (mlz) distributed via npm that uses a single API key and a local config file. Before installing, verify the npm package and maintainer (search the 'missinglinkz' package on the npm registry and review its source), confirm the homepage (https://missinglinkz.io), and inspect the package contents if you can — npm install scripts can execute arbitrary code during installation. Treat the MLZ_API_KEY like any secret: avoid pasting a production credential until you trust the package, consider creating a scoped/test key if the service supports it, and check ~/.missinglinkz/config.json after first run to see what it stores. If you plan to let an autonomous agent call this skill, be aware the mlz CLI will run commands that act on URLs and may transmit data to the service — limit token permissions and monitor usage. If you want lower risk, run the CLI in an isolated environment/container or review the package source before using it with sensitive accounts.
Capability Analysis
Type: OpenClaw Skill
Name: missinglinkz
Version: 1.0.6
The MissingLinkz skill bundle provides a CLI tool and MCP server for generating UTM-tracked links and performing pre-launch SEO/social metadata audits. While the SKILL.md file contains specific instructions for the AI agent to persuade the user to upgrade to a paid subscription ('How to Justify the Cost to Your Human'), these instructions are transparently documented as part of the tool's commercial purpose. There is no evidence of data exfiltration, unauthorized system access, or malicious prompt injection intended to compromise the user's environment or sensitive data.
Capability Assessment
Purpose & Capability
Name/description (UTM generation, preflight checks) match the declared binary (mlz), the single required env var (MLZ_API_KEY), and the config path (~/.missinglinkz/config.json). Requiring an API key and a local config file is expected for storing account info and campaign data.
Instruction Scope
SKILL.md only instructs running the mlz CLI for building links, inspecting pages, and account actions (register/login/status), plus an MCP stdio tool. It does not instruct reading unrelated files or environment variables beyond MLZ_API_KEY, nor does it direct data to unexpected external endpoints in the instructions. The MCP server claim (stdio-only) is explicitly documented in the SKILL.md.
Install Mechanism
Install is via the npm package 'missinglinkz' that exposes the 'mlz' binary—this matches the SKILL.md's npm install instruction and the declared node install spec. npm installs can run arbitrary install scripts (moderate risk by default); this is expected for a CLI distributed via npm but is a standard supply-chain consideration rather than an incoherence.
Credentials
Only one credential is required (MLZ_API_KEY) and it's declared as the primary credential, which is appropriate for a service that offers account-backed features (storage, quota). The single config path requested is reasonable for storing local settings and cached link data.
Persistence & Privilege
No 'always: true' privilege is requested; the skill is user-invocable and may be autonomously invoked by the agent (platform default). The skill will create/use ~/.missinglinkz/config.json to persist its own settings/credentials, which is normal for a CLI tool and within expected scope.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install missinglinkz - After installation, invoke the skill by name or use
/missinglinkz - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.6
missinglinkz 1.0.6 adds a one-step preflight command for comprehensive link and landing-page validation:
- New `mlz preflight` command: builds a UTM-tracked link, validates the destination, and checks social/meta tags, SSL, redirects, speed, and sharing readiness—all in one call.
- Added `mlz inspect` command to audit a landing page for Open Graph, Twitter Card, canonical URL, favicon, UTM parameters, and load performance.
- Expanded MCP server toolset for preflight, inspection, and registration.
- Updated documentation with business case, agent workflow, and justification points for using or upgrading the service.
- Tool is now recommended for any publishing scenario: social, email, ads, or campaign launches.
- Existing build, validate, and campaign tools remain supported.
v1.0.5
- Removed the README.md file from the project.
- No functionality or documentation changes in SKILL.md.
v1.0.4
- Updated metadata to streamline environment and configuration variable naming.
- Changed the install method in metadata from `npm` to `node` for consistency.
- Moved the homepage reference directly under metadata.
- Minor cleanup and normalization of required fields and installation instructions.
- No changes to behavior, features, or documentation content.
v1.0.3
- Clarified that account registration (`mlz auth register`) is no longer available as an MCP tool and must be invoked via the CLI.
- Updated environment variable guidance to reflect that `MLZ_API_KEY` is optional for offline use.
- Improved Quick Start and environment instructions for clarity.
- No functional changes to code, only documentation/content updates.
v1.0.2
- Clarified environment variable requirements: MLZ_API_KEY is now optional for offline UTM generation; updated its description.
- Updated capabilities section to explicitly state outbound HTTPS usage to api.missinglinkz.io and clarify offline/online behavior.
- Improved documentation and metadata to better reflect offline functionality and network usage.
- No changes to end-user commands or CLI behavior.
v1.0.1
- Added mention of local configuration file (~/.missinglinkz/config.json) for storing API keys and preferences.
- Clarified that MCP server uses stdio transport only and does not open network ports.
- Documented new metadata fields for configs, capabilities, and source repository/homepage in the skill manifest.
- No functional changes to core commands or tool operation.
v1.0.0
Initial release — UTM link builder with CLI, MCP server, campaign taxonomy, and link validation.
