Card News
Return the last-3-month news view of one exact card variant in compact format.
When To Use
When the user asks about recent changes, news, or updates for a credit card. Trigger phrases: "card-news", "any changes", "recent news", "what's new with", "updates for".
Workflow
- 1. Resolve card identity — normalize and match to one exact variant. If ambiguous, return a numbered choice list and stop.
- Search — run one Brave Search API call with freshness filter for recent results.
- Fetch pages — fetch the top news pages before deciding whether another search is needed.
- Filter — apply 3-month lookback window and inclusion rules.
- Pace any follow-up searches — if another Brave search is needed, wait briefly instead of bursting requests.
- Compile — assemble the news report.
- 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
Run one Brave Search API call with freshness filter:
CODEBLOCK0
The freshness=p3m parameter limits results to the past 3 months, matching the lookback window. Replace CURRENT_YEAR with the actual current year.
Search Budget Rule
Brave may rate-limit after only a few closely spaced requests. Treat search as scarce and paced.
- - Start with one search.
- Fetch the top result pages before deciding whether another 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 it still fails, continue with the best evidence already gathered and note the limitation in
## 📋 Confidence Notes.

Recency Rules
- - Use a 3-month lookback window only.

- Exclude: generic issuer chatter, evergreen "best card" articles that do not describe a recent change.
Step 4: Fetch Pages
