Subscriptions

Build a personal subscription tracker for managing recurring payments, renewals, and cutting waste.

Security Scan

Instruction-only, local subscription-tracker that is internally consistent with its stated purpose and does not request credentials, installs, or network access.

Purpose & Capability

The name/description describe a personal subscription tracker and the SKILL.md content implements that: creating ~/subscriptions, adding markdown entries, surfacing totals and reminders. There are no unrelated requirements (no cloud credentials, no external binaries) so the declared purpose matches the requested capabilities.

Instruction Scope

Runtime instructions are limited to creating and managing local markdown files under ~/subscriptions/, tracking cost/billing/use/value, and surfacing reminders. The instructions do not tell the agent to read unrelated system files, environment variables, or send data to external endpoints.

Install Mechanism

No install spec and no code files — this is instruction-only. That is the lowest-risk install profile: nothing is downloaded or written beyond the local files the skill itself instructs the agent to create.

Credentials

The skill requests no environment variables, credentials, or config paths. The only sensitive data referenced is a payment method 'Card: Visa •4242' pattern; the instructions do not request full card numbers or unrelated secrets, so the environment/credential access is proportional to the task.

Persistence & Privilege

always is false and the skill does not require elevated privileges or modifications to other skills. It does instruct creating files under the user's home directory, which is expected for a local tracker and is a normal scope of persistence.

Assessment

This skill appears to be a simple, local subscription tracker and is internally consistent, but review these practical points before installing: 1) Source is unknown and there's no homepage—exercise the usual caution with third-party skills even if they appear benign. 2) The skill will create files in ~/subscriptions/; confirm you are comfortable with that location and file ownership/permissions. 3) Avoid storing full payment card numbers or other sensitive secrets in plaintext; keep only safe metadata (e.g., last 4 digits) or use an encrypted/secure store. 4) If you use an autonomous agent, verify it will not transmit the subscription data externally—this skill's instructions don't require network access, but agent runtime policies matter. 5) Back up or encrypt the subscriptions directory if it will contain sensitive financial notes.

Core Behavior

• User mentions subscription → add to tracker
• User asks about spending → surface totals
• Alert before renewals and price increases
• Create ~/subscriptions/ as workspace

What To Track

• Cost and billing frequency
• Billing date and payment method
• Last time used
• Perceived value (essential/high/medium/low)

What To Surface

• "You spend $165/month on subscriptions"
• "HBO unused for 3 weeks"
• "Adobe renews in 30 days — $660"
• "3 subscriptions bill this week"

Review Triggers

• Unused 30+ days → suggest cancel
• Price increased → flag it
• Annual renewal approaching → remind 7 days before
• Quarterly prompt: "still getting value?"

Cancelled Log

# cancelled.md
## 2024
- Hulu: Feb 1 (never used) — saved $18/mo

Progressive Enhancement

• Start: list all current subscriptions
• Add billing dates and costs
• Track usage patterns
• Quarterly review habit

What NOT To Do

• Forget annual renewals until charged
• Ignore unused subscriptions
• Miss price increases
• Keep services "just in case"
