Ask Oracle Skill
Leverage the Oracle CLI to tap into GPT-5 Pro / GPT-5.1 for hard problems that benefit from extended reasoning and large code context.
When to Use
Invoke this skill when:
- •Problem requires deep reasoning beyond single-response analysis
- •Debugging complex issues across large codebases (100k+ lines)
- •Architectural decisions need careful evaluation with full context
- •Performance optimization requires comprehensive code analysis
- •Security reviews need thorough codebase inspection
- •Standard Claude analysis feels insufficient
- •Problem statement includes "hard", "complex", "architectural", "across the codebase"
Core Capabilities
The Oracle CLI (bunx @steipete/oracle) provides:
- •GPT-5 Pro (default): Advanced reasoning for difficult problems
- •GPT-5.1: Experimental model with different reasoning approach
- •File context: Attach entire directories/files (up to ~196k tokens)
- •Sessions: Long-running background sessions with resume capability
- •Token reporting: Inspect file token costs before calling API
Workflow
Step 1: Assess the Problem
Determine if oracle is needed:
- •Is the problem genuinely hard/complex?
- •Does it benefit from seeing more code context?
- •Would standard Claude response be insufficient?
If yes, proceed. If it's a simple question, just answer directly.
Step 2: Gather Relevant Context
Identify files/directories to attach using --file:
- •Architecture files (README, package.json, main entry points)
- •Relevant source directories (
src/,lib/, etc.) - •Configuration files (tsconfig, build config, etc.)
- •Tests if they illuminate the problem
- •Error logs or reproduction scripts
Exclude:
- •Node modules (
node_modules/) - •Build artifacts (
dist/,build/) - •Large vendored code
- •Binary files
Step 3: Choose Model and Preview
For most hard problems, use default GPT-5 Pro:
bunx @steipete/oracle --prompt "Your question here" --file src/ docs/ --preview
For experimental approach, try GPT-5.1:
bunx @steipete/oracle --prompt "Your question here" --file src/ docs/ --model gpt-5.1 --preview
Always preview first to check token usage:
bunx @steipete/oracle --prompt "Question" --file src/ --files-report --preview
Step 4: Review Token Report
When using --files-report, output shows token costs per file:
Files Report: src/components/form.tsx: 3,245 tokens src/utils/helpers.ts: 1,023 tokens src/api/client.ts: 2,156 tokens Total: 6,424 tokens (under ~196k budget)
If total exceeds budget:
- •Remove less relevant files
- •Focus on key directories only
- •Exclude verbose files (logs, generated code)
- •Ask a more specific question to reduce needed context
Step 5: Execute Query
Once satisfied with preview, run without --preview to actually call the model:
bunx @steipete/oracle --prompt "Your question here" --file src/ docs/ --slug "my-problem"
Oracle runs as background session - terminal can close without losing work.
Step 6: Monitor or Resume Session
To attach to running session:
bunx @steipete/oracle session <session-id>
To list recent sessions (last 24h):
bunx @steipete/oracle status
To specify custom session slug (easier to remember):
bunx @steipete/oracle --slug "auth-flow-design" --prompt "..." --file src/
Later, attach via slug:
bunx @steipete/oracle session auth-flow-design
Key Options
| Option | Purpose | Example |
|---|---|---|
--prompt | The question to ask | --prompt "Why does this auth flow fail?" |
--file | Attach files/dirs (repeatable) | --file src/ docs/ --file error.log |
--slug | Human-memorable session name | --slug "perf-optimization-review" |
--model | Which model to use | --model gpt-5.1 (default: gpt-5-pro) |
--engine | api or browser | --engine api (default: auto-detect) |
--files-report | Show token per file | Helps optimize context |
--preview | Validate without calling API | Test before spending tokens |
--dry-run | Show token estimates only | Safer than preview |
--heartbeat | Progress updates (seconds) | --heartbeat 30 (default) |
Common Patterns
Hard Debugging Question
bunx @steipete/oracle \ --prompt "Why does this auth flow fail on mobile? Trace through the code flow." \ --file src/auth/ src/api/ docs/AUTH.md \ --slug "mobile-auth-debug" \ --files-report \ --preview
Architectural Review
bunx @steipete/oracle \ --prompt "Review the state management architecture. What are risks and improvements?" \ --file src/store/ src/components/ README.md \ --slug "state-arch-review"
Performance Analysis
bunx @steipete/oracle \ --prompt "Where are the performance bottlenecks in this renderer?" \ --file src/renderer/ performance-logs.txt \ --slug "renderer-perf" \ --files-report
Security Review
bunx @steipete/oracle \ --prompt "Identify security concerns in the authentication and API layers." \ --file src/auth/ src/api/ src/middleware/ \ --slug "security-audit"
Best Practices
- •Always preview first: Use
--previewor--files-reportto inspect tokens before committing budget - •Use memorable slugs: Makes it easier to resume and reference later
- •Ask focused questions: More specific = better reasoning. Avoid "review everything"
- •Provide context in prompt: "We're building X in domain Y, and problem is Z"
- •Attach key architecture docs: READMEs, design docs help oracle understand intent
- •Keep files under 1MB: Automatic rejection, so plan accordingly
- •Use browser engine for API-less runs: Falls back to browser if no OPENAI_API_KEY set
- •Check token budget: ~196k tokens max per request (files + prompt)
Examples
Example 1: Complex Bug Investigation
bunx @steipete/oracle \ --prompt "This form submission intermittently fails with 'network timeout'. Walk through the request/response cycle, check timeout configs, and trace where it might stall." \ --file src/components/Form.tsx src/api/client.ts src/hooks/useSubmit.ts \ --files-report \ --preview
Example 2: Design Review with Alternatives
bunx @steipete/oracle \ --prompt "We're using redux for state management in a 50k LOC codebase. Is this still optimal? What are 2-3 alternatives worth considering?" \ --file src/store/ docs/ARCHITECTURE.md package.json \ --slug "state-mgmt-design"
Example 3: Resume Previous Session
# Earlier you ran: bunx @steipete/oracle --prompt "..." --slug "my-problem" # Now attach to it: bunx @steipete/oracle session my-problem
Edge Cases & Troubleshooting
Files too large (>1MB):
- •Exclude vendored code, logs, or split context
- •Focus on key files only
Token budget exceeded (~196k):
- •Show
--files-reportto see cost per file - •Reduce number of files or directories
- •Ask more specific question to require less context
Session doesn't exist:
- •Check spelling of slug/ID
- •Run
bunx @steipete/oracle statusto list recent sessions - •Create new session if needed
OPENAI_API_KEY not set:
- •Oracle falls back to browser engine
- •Use
--engine browserexplicitly if preferred - •Set API key to use API engine for background sessions
Preview shows too many tokens:
- •Exclude directories with large generated files
- •Keep only most relevant source files
- •Split into multiple focused queries
Implementation Notes
- •Oracle CLI is installed via
bunx @steipete/oracle(no local install needed) - •Sessions run in background; terminal close doesn't stop them
- •Responses stream via heartbeat (default 30s intervals)
- •Use
--slugfor easier session management in team workflows - •Token budget is per-request (~196k combined), not per session
When NOT to Use Oracle
- •Simple questions answerable in seconds
- •Trivial code changes or minor bugs
- •Context < 10k tokens
- •Answers need immediate turnaround (background sessions take time)
- •No code context needed (use standard Claude instead)
