high confidencePurpose & Capability
The skill's name/description (mortgage calculations, comparisons, prepayment) match the included scripts and SKILL.md. Minor inconsistency: SKILL.md and the scripts require Bash and python3, but the registry metadata lists no required binaries; the code embeds a Python calculator and shell glue, so python3 and a POSIX shell (Bash 4+) are actually needed.
Instruction Scope
SKILL.md instructs use of a local CLI and describes commands that read/write local files under the data directory, list/search logs, and print results to stdout. The scripts only operate on files in the configured data directory and stdout/stderr, and do not access network endpoints or unrelated system paths.
Install Mechanism
No install spec or remote downloads are present; this is instruction-only with bundled scripts. No network downloads or archive extraction are performed by the skill itself.
Credentials
No credentials or secrets are requested. The only environment configurables are MORTGAGE_CALCULATOR_DIR and standard XDG_DATA_HOME; these are reasonable for changing the local data path.
Persistence & Privilege
The skill writes persistent data to a directory in the user's home (~/.local/share/mortgage-calculator by default), creating data.log and history.log. This is expected for a logging tool, but users should be aware it keeps a local audit/history of commands and entries.
Assessment
This skill appears to do what it says: mortgage calculations and simple local logging. Before installing, note: (1) it requires a Bash-compatible shell and python3 at runtime even though the registry did not list required binaries — ensure your environment has python3 and Bash 4+; (2) it will create ~/.local/share/mortgage-calculator/ (unless you set MORTGAGE_CALCULATOR_DIR) and write data.log and history.log there, which may contain sensitive financial notes you enter; (3) there are no network calls or secret exfiltration in the provided scripts, but you should still review the bundled scripts and decide whether you want the local logs to exist on the host or redirect them to a different directory. If you plan to automate or share the machine, consider setting MORTGAGE_CALCULATOR_DIR to a controlled location or audit the files before running.Like a lobster shell, security has layers — review code before you run it.
