- Instagram: migrate /v1/ to /v2/ ScrapeCreators endpoint (v1 deprecated Feb 2026)
- OpenAI: switch fallback chain to [gpt-5-mini, gpt-4.1-mini, gpt-4.1] (8x cheaper,
gpt-5-mini is the first mini model supporting web_search with filters.allowed_domains)
- xAI: use explicit grok-4-1-fast-non-reasoning (bare name aliases to reasoning variant)
- xAI: pass from_date/to_date natively to x_search tool config instead of prompt-only
- Polymarket: correct rate limit comment (15K/10s, not 350/10s)
- test_models: update xAI model expectations to grok-4-1-fast (matching
current XAI_POLICY_MAP)
- test_openai_reddit: update fallback order assertion to gpt-4.1 (matching
current MODEL_FALLBACK_ORDER)
- test_codex_auth: expect 'reddit' not 'web' when no API keys (Reddit
is available via public JSON fallback)
- test_truthsocial: convert from pytest-style classes to unittest.TestCase,
fix import path to use sys.path.insert pattern (matching all other tests)
- Fix invalid YAML in SKILL.md argument-hint (closes#8)
Wrapped value in single quotes to properly escape double quotes
- Add automatic model fallback for GPT-5 access errors (closes#9)
When OpenAI returns 400 for unverified orgs, retry with gpt-4o
- Add tests for model fallback logic
