# Oracle (CLI) — 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 outputs as advisory: verify against the codebase + tests. ## Main use case (browser, GPT‑5.2 Pro) Default workflow here: `--engine browser` with GPT‑5.2 Pro in ChatGPT. This is the “human in the loop” path: it can take ~10 minutes to ~1 hour; expect a stored session you can reattach to. Recommended defaults: - Engine: browser (`--engine browser`) - Model: GPT‑5.2 Pro (either `--model gpt-5.2-pro` or a ChatGPT picker label like `--model "5.2 Pro"`) - Attachments: directories/globs + excludes; avoid secrets. ## Golden path (fast + reliable) 1. Pick a tight file set (fewest files that still contain the truth). 2. Preview what you’re about to send (`--dry-run` + `--files-report` when needed). 3. Run in browser mode for the usual GPT‑5.2 Pro ChatGPT workflow; use API only when you explicitly want it. 4. If the run detaches/timeouts: reattach to the stored session (don’t re-run). ## Commands (preferred) - Show help (once/session): - `npx -y @steipete/oracle --help` - Preview (no tokens): - `npx -y @steipete/oracle --dry-run summary -p "<task>" --file "src/**" --file "!**/*.test.*"` - `npx -y @steipete/oracle --dry-run full -p "<task>" --file "src/**"` - Token/cost sanity: - `npx -y @steipete/oracle --dry-run summary --files-report -p "<task>" --file "src/**"` - Browser run (main path; long-running is normal): - `npx -y @steipete/oracle --engine browser --model gpt-5.2-pro -p "<task>" --file "src/**"` - Manual paste fallback (assemble bundle, copy to clipboard): - `npx -y @steipete/oracle --render --copy -p "<task>" --file "src/**"` - Note: `--copy` is a hidden alias for `--copy-markdown`. ## Attaching files (`--file`) `--file` accepts files, directories, and globs. You can pass it multiple times; entries can be comma-separated. - Include: - `--file "src/**"` (directory glob) - `--file src/index.ts` (literal file) - `--file docs --file README.md` (literal directory + file) - Exclude (prefix with `!`): - `--file "src/**" --file "!src/**/*.test.ts" --file "!**/*.snap"` - Defaults (important behavior from the implementation): - Default-ignored dirs: `node_modules`, `dist`, `coverage`, `.git`, `.turbo`, `.next`, `build`, `tmp` (skipped unless you explicitly pass them as literal dirs/files). - Honors `.gitignore` when expanding globs. - Does not follow symlinks (glob expansion uses `followSymbolicLinks: false`). - Dotfiles are filtered unless you explicitly opt in with a pattern that includes a dot-segment (e.g. `--file ".github/**"`). - Hard cap: files > 1 MB are rejected (split files or narrow the match). ## Budget + observability - Target: keep total input under ~196k tokens. - Use `--files-report` (and/or `--dry-run json`) to spot the token hogs before spending. - If you need hidden/advanced knobs: `npx -y @steipete/oracle --help --verbose`. ## Engines (API vs browser) - Auto-pick: uses `api` when `OPENAI_API_KEY` is set, otherwise `browser`. - Browser engine supports GPT + Gemini only; use `--engine api` for Claude/Grok/Codex or multi-model runs. - **API runs require explicit user consent** before starting because they incur usage costs. - Browser attachments: - `--browser-attachments auto|never|always` (auto pastes inline up to ~60k chars then uploads). - Remote browser host (signed-in machine runs automation): - Host: `oracle serve --host 0.0.0.0 --port 9473 --token <secret>` - Client: `oracle --engine browser --remote-host <host:port> --remote-token <secret> -p "<task>" --file "src/**"` ## Sessions + slugs (don’t lose work) - Stored under `~/.oracle/sessions` (override with `ORACLE_HOME_DIR`). - Runs may detach or take a long time (browser + GPT‑5.2 Pro often does). If the CLI times out: don’t re-run; reattach. - List: `oracle status --hours 72` - Attach: `oracle session <id> --render` - Use `--slug "<3-5 words>"` to keep session IDs readable. - Duplicate prompt guard exists; use `--force` only when you truly want a fresh run. ## Prompt template (high signal) Oracle starts with **zero** project knowledge. Assume the model cannot infer your stack, build tooling, conventions, or “obvious” paths. Include: - Project briefing (stack + build/test commands + platform constraints). - “Where things live” (key directories, entrypoints, config files, dependency boundaries). - Exact question + what you tried + the error text (verbatim). - Constraints (“don’t change X”, “must keep public API”, “perf budget”, etc). - Desired output (“return patch plan + tests”, “list risky assumptions”, “give 3 options with tradeoffs”). ### “Exhaustive prompt” pattern (for later restoration) When you know this will be a long investigation, write a prompt that can stand alone later: - Top: 6–30 sentence project briefing + current goal. - Middle: concrete repro steps + exact errors + what you already tried. - Bottom: attach *all* context files needed so a fresh model can fully understand (entrypoints, configs, key modules, docs). If you need to reproduce the same context later, re-run with the same prompt + `--file …` set (Oracle runs are one-shot; the model doesn’t remember prior runs). ## Safety - Don’t attach secrets by default (`.env`, key files, auth tokens). Redact aggressively; share only what’s required. - Prefer “just enough context”: fewer files + better prompt beats whole-repo dumps.
