Fertigation

Fertigation reference — injecting fertilizers through irrigation systems, nutrient scheduling, injection methods, and crop-specific programs. Use when design...

Security Scan

The skill is a local, read-only fertigation reference: its files and runtime instructions are consistent with the stated purpose and do not request credentials or perform external network installs.

Purpose & Capability

Name/description match the delivered content: an offline reference for fertigation. The included script prints reference material and the SKILL.md maps commands to that script. No unrelated credentials, binaries, or cloud access are requested.

Instruction Scope

SKILL.md directs the agent to run the bundled scripts/script.sh with specific subcommands. The script content shown only emits static help text (no file reads, writes, network endpoints, or unspecified data collection). The only configuration mentioned is an optional FERTIGATION_DIR for data storage; that is proportional to a local reference tool.

Install Mechanism

No install spec is present (instruction-only with an included script). This is low-risk: nothing is downloaded or extracted from external URLs and no package managers are invoked.

Credentials

The skill declares no required environment variables or credentials. The single documented config variable (FERTIGATION_DIR) is reasonable for a local data directory and does not imply elevated access.

Persistence & Privilege

always is false and the skill is user-invocable. It does not request persistent elevation or modification of other skills or system-wide settings. Autonomous invocation is allowed by default but presents no special risk given the skill's local, non-network behavior.

Assessment

This skill appears to be a straightforward, local reference: it prints agricultural guidance from an included shell script and does not request keys or perform network installs. Before enabling, you may want to: (1) quickly scan the remainder of scripts/script.sh for any unexpected commands (curl, wget, ssh, file writes), (2) confirm you are comfortable with autonomous invocation (the agent may run the script if asked), and (3) if you plan to set FERTIGATION_DIR, ensure it points to a directory you control. If you see any network calls or commands that write outside a local sandbox, treat that as suspicious and do not enable the skill.

Fertigation — Fertigation Systems Reference

Quick-reference skill for fertigation techniques, nutrient management, and injection system design.

When to Use

• Designing fertigation systems for drip or sprinkler irrigation
• Calculating fertilizer injection rates and concentrations
• Selecting injection equipment (Venturi, positive displacement, proportional)
• Planning nutrient schedules for different crop growth stages
• Troubleshooting fertigation uniformity and compatibility issues
