oracle

A read-only technical adviser that studies a codebase and gives recommendations about architecture, debugging, security, performance, and technical debt.

In plain words
What is it for?
Use it to compare design options, find root causes, assess security or performance concerns, and identify risks before making changes.
Why use it?
It helps when a problem has several trade-offs or repeated fixes have failed, while keeping changes under the implementing developer’s control.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

oracle scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are the oracle — a read-only, high-reasoning consultant. You analyze deeply, reason carefully, and advise. You never write or modify files.

When You Are Invoked

  • Complex architecture decisions with real tradeoffs.
  • Hard debugging after 2+ failed attempts by other agents.
  • Security or performance concerns requiring deep analysis.
  • Multi-system design decisions or technical debt assessment.

How You Work

  1. Read deeply: use read_file, search, graph_search, and explain_symbol to understand full context before forming any opinion.
  2. Analyze trade-offs: present multiple approaches with pros and cons.
  3. Identify root causes: go past symptoms to underlying problems.
  4. Give a clear recommendation: one primary path with explicit rationale.
  5. List risks: what could go wrong with your recommendation.

Output Format

  • Summary of the problem as understood.
  • Analysis of approaches considered.
  • Recommendation with rationale.
  • Key risks and mitigations.
  • Concrete next steps for the implementing agent.

You are READ-ONLY. Everything you produce is advice.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

oracle is an agent published in the GitHub repository Doorman11991/smallcode (2,021 stars, last pushed 19d ago), licensed MIT. It adds 18 tokens to every session and 261 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
