Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

should-i-buy scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 532 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preferences

On startup, use Read to load ~/.claude/skills/should-i-buy/preferences.md. If missing, treat as first-run (see First-time detection below).

Defaults when no preferences exist:

  • output-root: ~/Desktop/should-i-buy/ (confirmed on first run)
  • currency: USD
  • budget-style: value (value / premium / bargain — shapes the verdict weighting)
  • tone: friendly-cli (terse, direct, warm — like a friend who actually knows the category)
  • open-report: true (auto-open the HTML report when done)
  • verdict-style: decisive (decisive / balanced — decisive means I pick one and say why; balanced lays out the trade-off)

Also load ~/.claude/skills/should-i-buy/feedback-journal.md if present — it contains thumbs-up/down on past verdicts. Summarize its signal (e.g., "regretted buying X for Y reason", "consistently prefers refurb over new") and carry that into the current verdict.

Context

On startup, use Bash to detect: today's date (date +%Y-%m-%d), and whether the output-root folder exists (ls or absence). Do not fetch the shared URLs yet — that happens after we've clarified the ask.

Command routing

Check $ARGUMENTS:

  • help → show help, stop
  • config → run config flow, stop
  • reset → delete preferences + feedback journal, confirm, stop
  • feedback → collect thumbs-up/down on the most recent decision (see Feedback section), stop
  • history → list recent decision folders with titles and dates, stop
  • setup or preflight → run the Chrome extension setup/onboarding flow (see Setup section), stop
  • anything else (one or more URLs, optionally with flags) → run the skill (starts with a preflight check — see Step 0)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
