Card Compare

Return a compact side-by-side comparison of two exact card variants.

When To Use

When the user asks to compare two credit cards. Trigger phrases: "card-compare", "compare", "vs", "versus", "which is better", "[card A] or [card B]".

Input Format

The user provides two card names separated by "vs", "versus", "or", or a comma:

• card-compare Amex Gold vs Chase Sapphire Preferred
• card-compare CSR, Venture X

Workflow

1. Parse two card names from the input.
2. Resolve each card — normalize and match to exact variants. If either is ambiguous, return a numbered choice list for that card and stop.
3. Search — use the platform's WebSearch tool by default. If BRAVE_API_KEY is available and curl exists, you may use one Brave Search API call instead for faster results.
4. Fetch pages — use WebFetch by default to fetch issuer and approved secondary pages after the search completes.
5. Pace any follow-up searches — if another search is needed, wait briefly instead of bursting requests.
6. Compile — assemble side-by-side report.
7. Confidence — flag uncertain or conflicting claims.

Step 1: Card Identity Resolution

Common Abbreviations

Only shorthands and ambiguous names need entries here. Cards with full, unambiguous names (e.g., "Chase Marriott Bonvoy Boundless", "Chase United Explorer", "American Express Hilton Honors Aspire") are resolved via search — no table entry needed.

Step 2: Search

Use the platform's WebSearch and WebFetch tools by default. If BRAVE_API_KEY is available and the runtime also provides curl, you may use Brave Search API instead for faster and more repeatable search results.

Optional Brave template:

curl -sS "https://api.search.brave.com/res/v1/web/search?q=CARD_A+vs+CARD_B+compare&count=20" \
  -H "X-Subscription-Token: $BRAVE_API_KEY"

Search Budget Rule

Treat search as scarce and paced. Built-in web search is the default path; if Brave mode is used, it may rate-limit after only a few closely spaced requests.

• Start with one search.
• Fetch the issuer and approved secondary pages before deciding whether any additional search is needed.
• If an extra search is needed, wait about 2 to 5 seconds first.
• If Brave returns 429, wait about 8 to 15 seconds and retry once.
• If Brave is unavailable, continue with WebSearch + WebFetch.
• If it still fails, continue with the best evidence already gathered and note the limitation in ## 📋 Confidence Notes.

Source Policy

• Issuer-first: check both cards' official product pages before secondary sources.
• Max 5 secondary sources from: NerdWallet (preferred), The Points Guy (preferred), Doctor of Credit (preferred), One Mile at a Time (preferred), Bankrate (preferred), Upgraded Points.
• Disallowed: Reddit, Facebook, Instagram, TikTok, X, YouTube, referral links, user forums.

Step 4: Fetch Pages

Pick the issuer URL for each card and up to 2 secondary URLs (prefer nerdwallet.com and thepointsguy.com) from the search results. Fetch in parallel with WebFetch.

An approved secondary page means a URL whose hostname matches one of the approved secondary domains named in this skill. Do not fetch or cite secondary pages from any other domain.

URL Safety Rules

• Prefer WebFetch for page retrieval. Use curl only for the optional Brave Search API calls above, not for arbitrary result URLs.
• Never execute a shell command that interpolates a raw URL taken directly from search results.
• Only fetch URLs when all of the following are true:
  1. scheme is https
  2. hostname matches a supported issuer domain or an approved secondary domain from this skill
  3. the URL is being passed to WebFetch, not inserted into a shell pipeline
• If a result URL fails those checks, skip it and use the next valid result.

Search snippets are too shallow for accurate comparisons — the actual pages have complete rate tables, credit lists, and benefit details.

Output Rules

Confidence Definitions

• confirmed: supported by issuer terms or multiple approved sources
