## What it does

Oracle packages project files and a task prompt into a one-shot bundle for another model, such as GPT-5.6 in ChatGPT or an API endpoint. It offers an external sanity check for tricky debugging, refactoring, or system design. Treat the output as advisory and test it against your test suite.

Context selection relies on the `--file` argument, accepting directory paths and glob exclusions prefixed with an exclamation mark. The tool respects `.gitignore` and ignores standard build directories like `node_modules`, `dist`, and `.turbo`. Files exceeding 1 MB trigger an error by default to keep the total payload under the 196k token threshold.

When `OPENAI_API_KEY` is not detected, oracle defaults to browser automation via Chrome. Running over the API requires explicit user confirmation because provider usage charges can add up. Never feed unredacted `.env` files or secret keys into the prompt bundle.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add steipete/oracle --skill oracle -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/oracle/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/oracle/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add steipete/oracle --skill oracle -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/oracle/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add steipete/oracle --skill oracle -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/oracle/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install steipete/oracle oracle
```

2. **Manually: put the files in place**
- File: `.github/skills/oracle/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add steipete/oracle --skill oracle -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/steipete/oracle --path skills/oracle
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/oracle/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add steipete/oracle --skill oracle -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/steipete/oracle/tree/HEAD/skills/oracle/SKILL.md

## When to use it
- send selected repository files to a second model for code review
- package source code while excluding tests, build artifacts, and secrets
- run advisory design checks against GPT-5.6 Sol in browser mode
- preview token consumption and bundle contents with `--dry-run summary`

## Example prompts
- Review the architecture in `src/**` with oracle using GPT-5.6 Sol in browser mode.
- Run an oracle dry run with `--dry-run summary` on files in `src/` excluding test files.
- Inspect bundle token counts for `src/**` using oracle with `--files-report`.

# Oracle (CLI) — best use

Oracle bundles a prompt and selected files into a one-shot request so another
model can answer with real repository context through the API or browser. A
prompt is required; attach files only when they add necessary context. Treat
responses as advisory and verify them against the codebase and tests.

## Main use case (browser, GPT-5.6)

Use browser mode with GPT-5.6 when the ChatGPT account exposes it. GPT-5.6 Sol
and GPT-5.6 Sol Pro are distinct targets: base Sol uses the Extra High effort
setting, while Pro is a separate picker target for difficult or long-running
work.

Recommended defaults:

- Engine: browser (`--engine browser`)
- Base Sol: `--model gpt-5.6-sol`
- Base Sol maximum reasoning: `--browser-thinking-time extra-high` (Extra High)
- Explicit Pro effort on GPT-5.6 Sol: `--browser-thinking-time pro` (fails closed if Pro cannot be confirmed)
- Browser GPT-5.5 with Pro effort: `--model gpt-5.5 --browser-thinking-time pro`
- API Pro maximum reasoning: `--model gpt-5.6-sol --reasoning-mode pro --reasoning-effort max`
- Fallback: explicitly use `--model gpt-5.5-pro` when GPT-5.6 is unavailable
- Attachments: directories/globs plus excludes; never attach secrets by default

GPT-5.6 availability is account-dependent. Confirm the base Sol picker and
retain model-selection evidence. A bare `Pro` picker label proves picker
selection but does not, by itself, prove the server-side Pro generation.

## GPT-5.6 model selection

This version supports GPT-5.6 on both surfaces, but Pro selection differs:

- `gpt-5.6`: follow the GPT-5.6 family default
- `gpt-5.6-sol`: pin ChatGPT's `GPT-5.6 Sol` entry
- Browser: `gpt-5-pro` selects ChatGPT's `Pro` target
- API: `--reasoning-mode pro` enables Pro execution on `gpt-5.6-sol`; pair it with `--reasoning-effort max` for maximum reasoning

For base Sol, use:

```bash
oracle --engine browser --browser-manual-login --model gpt-5.6-sol \
  --browser-thinking-time extra-high \
  -p "<task>" --file "src/**"
```

For GPT-5.6 Sol Pro through the Responses API, use:

```bash
oracle --engine api --model gpt-5.6-sol \
  --reasoning-mode pro \
  --reasoning-effort max \
  -p "<task>" --file "src/**"
```

Do not use `--model "GPT-5.6 Sol Pro"`. Pro is intentionally handled as a
browser picker target and an API reasoning mode. Browser label validation rejects unknown future
variants such as `gpt-5.6-luna` instead of silently falling back to Sol; API
runs preserve such provider model IDs unchanged.

Browser mode maps these aliases to ChatGPT's Sol picker. API and multi-model
runs preserve the corresponding first-party OpenAI model IDs; provider-qualified
and unrelated custom IDs remain pass-through values.

The GPT-5.6 browser support depends on the unified Intelligence picker. It
recognizes the current English and Chinese effort labels, avoids matching
