Depreciation

Calculate depreciation financial metrics and business data. Use when tracking expenses, analyzing investments, or generating financial reports.

Security Scan

The skill is internally consistent: a small CLI tool that stores and manipulates depreciation entries under ~/.depreciation with no network calls or extra credentials requested.

Purpose & Capability

Name/description match the included script and commands. The code implements add/list/search/export/stats/config for depreciation entries, which is coherent with the stated purpose.

Instruction Scope

SKILL.md directs the agent to run scripts/script.sh with specific commands. The script only reads/writes files under the data directory (default ~/.depreciation) and does not access other system config, secrets, or external endpoints.

Install Mechanism

No install spec or external downloads. The skill is instruction-only plus a bundled bash script; nothing is fetched from the network or extracted at install time.

Credentials

No required environment variables or credentials. The script respects an optional DEPRECIATION_DIR override and otherwise uses the user's home directory for storage—proportionate for its function.

Persistence & Privilege

always is false and the skill does not modify other skills or system-wide agent settings. It only creates/updates files beneath its own data directory.

Assessment

This skill is a small local CLI that stores data in ~/.depreciation (unless you set DEPRECIATION_DIR). Before installing, consider: (1) it will create and modify files in that directory (data.jsonl and config.txt), so back up any important files if you reuse that path; (2) it performs only local filesystem operations and makes no network calls or request for credentials; (3) review the script contents and file permissions if you require stricter controls (e.g., make the data directory private). Overall the behavior matches the description.
