✓
Purpose & Capability
The name/description (data analysis on user-provided files) matches the declared footprint: no binaries, no environment variables, no installs. Nothing requested appears unrelated to a data analyst role.
✓
Instruction Scope
SKILL.md only instructs the agent to operate on files provided via the upload_files parameter and to reference them by filename in the working directory. It does not ask for reading system files, secrets, or sending data to external endpoints.
✓
Install Mechanism
There is no install spec (instruction-only), so nothing is written to disk or downloaded during install. This is the lowest-risk pattern.
✓
Credentials
The skill requires no environment variables, credentials, or config paths. That aligns with a tool that only processes user-uploaded files.
✓
Persistence & Privilege
The skill is not forced-always and uses default invocation settings. It does not request persistent system presence or modify other skills or agent-wide settings.
Assessment
This skill is concise and internally consistent: it expects you to upload files the agent should operate on and to reference them by filename in code. Before using it, avoid uploading sensitive secrets (API keys, private keys, etc.), verify uploaded filenames match what you intend the agent to read, and confirm any template variables (e.g., $DATE$) are substituted correctly at runtime. If the skill later requests environment variables, downloads installers, or instructs reading files outside the uploaded working directory, stop and re-evaluate, as that would be a meaningful change.
