dvcrn 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.

Configuration
Scripts auto-load credentials from .env files. No manual setup in the session.
Load priority (first found wins):
- System environment variables
<cwd>/.substracker-skills/.env~/.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 list
bun scripts/main.ts s create --name "Netflix" --expiry-date 2026-04-07 --amount 15.99
bun scripts/main.ts s get <id>
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
