Phosphate

Phosphate fertilizer reference — P2O5 forms, application timing, soil testing, runoff management, crop requirements. Use when planning phosphorus fertilizati...

Security Scan

The skill is an offline/reference tool whose instructions invoke a local shell script to print phosphate/fertilizer guidance; its requirements and files align with that purpose and no suspicious behavior was found in the provided content.

Purpose & Capability

Name/description (phosphate fertilizer reference) match the files and commands: SKILL.md documents reference commands that invoke scripts/script.sh to print agricultural guidance. There are no unrelated binaries, services, or credentials requested.

Instruction Scope

SKILL.md instructs the agent to run local script commands (intro, products, soiltest, etc.). The script contents shown only emit static reference text (cat << EOF blocks). The instructions do not ask the agent to read unrelated system files, collect environment secrets, or transmit data externally.

Install Mechanism

No install spec is present; this is instruction-only plus a bundled script. No network downloads, package installs, or archive extraction are used in the manifest. The script is local and self-contained.

Credentials

No required environment variables, credentials, or config paths are declared. SKILL.md mentions a PHOSPHATE_DIR configuration variable as a default data dir, which is reasonable for a local reference tool; the provided script does not require secrets or external credentials.

Persistence & Privilege

always is false and the skill does not request elevated or persistent platform privileges. There is no evidence it modifies other skills or global agent settings.

Assessment

This skill appears to be a simple, local reference: it runs a bundled shell script that prints fertilizer guidance. Before installing or invoking it, you may: (1) review the remainder of scripts/script.sh (the file was truncated in the listing) to confirm there are no network calls, file writes, or subprocess executions; (2) run the script in a sandbox or container (e.g., inspect with less/cat, then run scripts/script.sh help) to verify behavior; (3) if you plan to let the agent invoke the skill autonomously, remember it will execute the local script but it does not request credentials or external access. If you see any lines that call curl/wget/ssh/telnet, or write to sensitive paths (e.g., /etc, ~/.ssh), treat those as red flags and do not proceed.
