What it does

Oracle is an agent skill from openclaw/openclaw. Oracle CLI second-model review/debug/refactor/design with selected files, dry-run token checks, API or browser engine.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. It works with OpenAI. The repository describes itself as: The AI that really does things. Any OS. Any Platform. The lobster way. 🦞. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/oracle”

Requirements

  • Node.js
  • A credential in OPENAI_API_KEY

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Pick a tight file set (fewest files that still contain the truth).
  2. Preview payload + token spend (--dry-run + --files-report).
  3. Use browser mode for long Pro thinking; API mode for explicit API calls.
  4. If the run detaches/timeouts: reattach to the stored session. Do not blindly re-run.

What it can do on your machine

Read from SKILL.md and the folder at commit 1eb5970. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OPENAI_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Oracle loads about 1.2k tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 555 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:116
    - Leave `.env`, key files, and auth tokens out of attachments unless the user asks to include them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

oracle

Oracle bundles a prompt + selected files for one second-model pass. Treat output as advisory; verify against code + tests.

Main path

Current CLI default model: gpt-5.5-pro. Browser engine is useful for long ChatGPT Pro runs; API engine is useful when OPENAI_API_KEY or Azure config is ready.

Recommended defaults:

  • Preview first: --dry-run summary --files-report
  • Browser long run: --engine browser --model gpt-5.5-pro
  • API explicit: --engine api --model gpt-5.5

Golden path

  1. Pick a tight file set (fewest files that still contain the truth).
  2. Preview payload + token spend (--dry-run + --files-report).
  3. Use browser mode for long Pro thinking; API mode for explicit API calls.
  4. If the run detaches/timeouts: reattach to the stored session. Do not blindly 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-5.5-pro -p "<task>" --file "src/**"

  • Manual paste fallback:

    • 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/**"
    • --file src/index.ts
    • --file docs --file README.md

  • Exclude:

    • --file "src/**" --file "!src/**/*.test.ts" --file "!**/*.snap"

  • Defaults (implementation behavior):

    • Default-ignored dirs: node_modules, dist, coverage, .git, .turbo, .next, build, tmp (skipped unless explicitly passed as literal dirs/files).
    • Honors .gitignore when expanding globs.
    • Does not follow symlinks.
    • Dotfiles filtered unless opted in via pattern (e.g. --file ".github/**").
    • Files > 1 MB rejected.

Engines (API vs browser)

  • Auto-pick: api when OPENAI_API_KEY is set; otherwise browser.
  • Browser supports GPT + Gemini only; use --engine api for Claude/Grok/Codex or multi-model runs.
  • Browser attachments:
    • --browser-attachments auto|never|always (auto pastes inline up to ~60k chars then uploads).
  • Remote browser host:
    • 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

  • Stored under ~/.oracle/sessions (override with ORACLE_HOME_DIR).
  • Runs may detach or take a long time (browser + Pro often does). If the CLI times out: do not 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, boundaries).
  • Exact question + what you tried + the error text (verbatim).
  • Constraints ("don't change X", "must keep public API", etc).
  • Desired output ("return patch plan + tests", "give 3 options with tradeoffs").

Attachments

  • Leave .env, key files, and auth tokens out of attachments unless the user asks to include them.

"Exhaustive prompt" restoration pattern

For long investigations, write a standalone prompt + file set so you can rerun days later:

  • 6-30 sentence project briefing + the goal.
  • Repro steps + exact errors + what you tried.
  • Attach all context files needed (entrypoints, configs, key modules, docs).

Oracle runs are one-shot; the model doesn't remember prior runs. "Restoring context" means re-running with the same prompt + --file … set (or reattaching a still-running stored session).

Can I use Oracle in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add openclaw/openclaw --skill oracle -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/oracle, .gemini/skills/oracle, .github/skills/oracle and .opencode/skills/oracle in your project.

What does Oracle need to run?

Going by SKILL.md and its folder, Oracle needs the command-line tools its instructions call (npx) and credentials named OPENAI_API_KEY. Our summary lists: Node.js; A credential in OPENAI_API_KEY.

Does Oracle access the network?

SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Oracle safe to install?
