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.
