Documentation:
- Added recommended models: Claude Haiku 4.5 and Qwen3
- Added Gotify setup instructions
- Updated API reference with new endpoints
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Updated prompts to explicitly require 'out_of_stock' when the AI's
reasoning mentions the product is not available, coming soon, pre-order,
or has a future availability date.
The AI was returning 'unknown' even when its reason clearly stated
"not available for purchase right now" - now it must use 'out_of_stock'.

Send /nothink as a separate message before the actual prompt,
with a mock assistant response. This properly disables thinking
mode for Qwen3/DeepSeek models.
Removed the ineffective think:false API parameter.

Default 4K context was truncating the HTML before the model could see it.
Added num_ctx: 16384 to all 4 Ollama API calls to ensure the full
~25K character HTML content fits in context.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The /nothink prefix in prompt text doesn't work for Qwen3/DeepSeek.
The correct way is to pass "think": false in the API request body.
- Added think: false to all 4 Ollama API calls (extract, verify,
stock status, arbitrate)
- Removed ineffective /nothink prefixes from prompts
- Kept stripThinkingTags() as additional fallback protection
Ref: https://docs.ollama.com/capabilities/thinking
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
These models output <think>...</think> blocks before their actual JSON
response when in "thinking mode". This fix:
1. Adds /nothink prefix to all AI prompts (EXTRACTION_PROMPT,
VERIFICATION_PROMPT, STOCK_STATUS_PROMPT, ARBITRATION_PROMPT)
to request models disable thinking mode
2. Adds stripThinkingTags() helper function that removes <think>
blocks from responses as a fallback if models ignore /nothink
3. Applies stripping in all parse functions before JSON extraction

When anchor price matches (user previously selected a specific variant),
we now call AI specifically to verify stock status for that price point.
- Add STOCK_STATUS_PROMPT focused on variant availability
- Add AIStockStatusResult interface
- Add verifyStockStatusWith{Anthropic,OpenAI,Ollama} functions
- Add tryAIStockStatusVerification export function
- Call stock verification when anchor price matches in scraper
The prompt instructs AI to only check stock for the specific variant at
the user's selected price, ignoring other variants that may be out of
stock. This fixes false "out of stock" reports on variant product pages.

Sonnet 4 is ~4-12x more expensive than Haiku 3.5.
Haiku 3.5 should still be capable enough for price extraction.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Users can now disable AI verification for individual products that
AI is having trouble with (e.g., Amazon products where AI keeps
picking the main buy box price instead of "other sellers").
Changes:
- Add ai_verification_disabled column to products table
- Add toggle in product detail page under "Advanced Settings"
- Pass skip flag to scrapeProductWithVoting
- Skip AI verification when flag is set
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Haiku was being too literal in price extraction, often "correcting"
valid alternative prices (like Amazon other sellers) to the main
buy box price.
Sonnet is more capable and should handle nuanced cases better.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
When the scraper finds multiple valid prices (e.g., Amazon main price +
other sellers), skip AI verification entirely. AI was "correcting"
valid alternative prices to the main buy box price.
Now with multiple candidates, users see all options in the modal and
choose themselves - no AI interference.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Amazon products can have multiple prices:
- Main buy box price
- "Other Sellers" prices
- Subscribe & Save prices
- New & Used prices
The scraper now extracts ALL prices, not just the main one. This allows
anchor price matching to find the specific price the user selected.
Also fixed AI verification overriding user's anchor price selection.
When user deliberately chose a price (e.g., "other sellers" at $52.91),
don't let AI "correct" it to the main buy box price ($79.99).
Changes:
- Amazon scraper now collects all price variants
- extractSiteSpecificCandidates handles allPrices array
- Anchor matching now always returns (no fall-through to AI override)
- Increased anchor tolerance from 10% to 15% for small sales
- Added debug logging showing all candidate prices
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The previous logic checked preferred method first, which could select
a wrong price even when anchor price was available. Now:
1. PRIORITY 1: Anchor price - if user confirmed a price, find closest
match (within 10% tolerance) across ALL candidates
2. PRIORITY 2: Preferred method - only used if no anchor match found
3. PRIORITY 3: Consensus voting
Also added debug logging to trace anchor price saving and retrieval.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
When a user confirms a price from the modal, we now store it as an
"anchor price". On subsequent refreshes, if multiple price candidates
are found (common with variant products like different sizes/colors),
we select the candidate closest to the anchor price.
This fixes the issue where variant products would randomly switch to
a different variant's price on refresh.
Changes:
- Add anchor_price column to products table
- Save anchor price when user confirms a price selection
- Use anchor price to select correct variant on refresh
- 20% tolerance - if no candidate is within 20% of anchor, fall back to consensus
