name: substracker description: Manage SubsTracker subscriptions and configuration via CLI scripts. Handles login, subscription CRUD, config updates, notifications, and dashboard queries. Use this skill whenever the user mentions subscriptions, recurring payments, subscription tracking, renewal reminders, payment history, notification configuration (Telegram, Bark, email, webhook, Gotify), or anything related to their SubsTracker instance — even if they just say "add a subscription", "what am I paying for", "check my renewals", "how much do I spend monthly", "update my Telegram config", "加个订阅", "我订阅了什么", "有哪些快到期了", "每月花多少钱", "续费", "订阅提醒", "通知设置", "看下订阅", "账单" without explicitly mentioning SubsTracker.

SubsTracker API Skill

Manage subscriptions via CLI scripts that wrap the SubsTracker REST API. The scripts handle authentication, cookie management, and retries — you just call a command and get JSON back.

Read scripts/types.ts for all field names, types, defaults, and descriptions (TSDoc comments).

Configuration

Scripts auto-load credentials from .env files. No manual setup in the session.

Load priority (first found wins):

1. System environment variables
2. <cwd>/.substracker-skills/.env
3. ~/.substracker-skills/.env

Required variables in .env:

SUBSTRACKER_URL=https://sub.example.com
SUBSTRACKER_USER=admin
SUBSTRACKER_PASS=your_password

If variables are missing, the script exits with a clear error. Ask the user to create their .env file.

Running Commands

Resolve the runtime: use bun if installed, otherwise npx -y bun.

All commands follow the same pattern:

bun <SKILL_DIR>/scripts/main.ts <command> [subcommand] [--flags]

Scripts output JSON to stdout (for you to parse) and log to stderr (for debugging). Authentication and session cookies are handled automatically — if a session expires, the script re-logs in and retries.

Command Reference

Login

bun scripts/main.ts login

Usually not needed — all commands auto-login when no session exists. Use this to verify credentials.

Subscriptions

bun scripts/main.ts s update <id> --amount 19.99
bun scripts/main.ts s delete <id>
bun scripts/main.ts s toggle <id> --active false
bun scripts/main.ts s renew <id> --amount 15.99 --note "March renewal"
bun scripts/main.ts s test-notify <id>

Presenting Results

When showing subscription data to the user, format JSON responses as readable tables or summaries — don't dump raw JSON. For example, a subscription list should look like a table with name, amount, cycle, next renewal date, and status.

Error Handling

• Missing env vars: script exits with instructions to create .env
• 401 Unauthorized: auto re-login and retry (once)
• API errors: response includes success: false and message explaining what went wrong
