I want to run a query using Claude 3.5 Sonnet through the browser automation mode. Is this supported or should I switch execution modes?

SKILL.md101 linessingle file

oracle — best use

Oracle bundles your prompt + selected files into one “one-shot” request so another model can answer with real repo context (API or browser automation). Treat output as advisory: verify against code + tests.

Main use case (browser, GPT‑5.2 Pro)

Default workflow here: --engine browser with GPT‑5.2 Pro in ChatGPT. This is the common “long think” path: ~10 minutes to ~1 hour is normal; expect a stored session you can reattach to.

Recommended defaults:

Engine: browser (--engine browser)
Model: GPT‑5.2 Pro (--model gpt-5.2-pro or --model "5.2 Pro")

Golden path

Pick a tight file set (fewest files that still contain the truth).
Preview payload + token spend (--dry-run + --files-report).
Use browser mode for the usual GPT‑5.2 Pro workflow; use API only when you explicitly want it.
If the run detaches/timeouts: reattach to the stored session (don’t re-run).

Commands (preferred)

Help:
- oracle --help
- If the binary isn’t installed: npx -y @steipete/oracle --help (avoid pnpx here; sqlite bindings).
Preview (no tokens):
- oracle --dry-run summary -p "<task>" --file "src/**" --file "!**/*.test.*"
- oracle --dry-run full -p "<task>" --file "src/**"
Token sanity:
- oracle --dry-run summary --files-report -p "<task>" --file "src/**"
Browser run (main path; long-running is normal):
- oracle --engine browser --model gpt-5.2-pro -p "<task>" --file "src/**"
Manual paste fallback:
- oracle --render --copy -p "<task>" --file "src/**"
- Note: --copy is a hidden alias for --copy-markdown.
