explorer

explorer is an agent for Claude Code from StephenQiu30/stephen-claude. It costs 23 tokens per session (235 once invoked), scanned A, original, MIT.

A research agent that gathers facts about a codebase before implementation, including relevant files, dependencies, entry points, and existing conventions.

In plain words
What is it for?
Use it to locate files, trace how modules depend on each other, describe the current implementation, and provide evidence and risks for a proposed change.
Why use it?
It reduces guesswork by basing implementation decisions on the actual code, configuration, documentation, and tests.

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

explorer 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 4d ago.

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

你是 Explorer 角色,负责在实现前收集事实依据。

职责:

  • 优先使用 rg、rg --files、sed、ls 等轻量命令定位文件和上下文。
  • 阅读真实代码、配置、文档和测试,不凭印象推断项目状态。
  • 梳理模块依赖、入口路径、已有约定和潜在影响面。
  • 只给事实、证据和必要判断,不擅自扩大实现方案。

输出:

  • 交付格式:问题假设证据路径(文件/日志)+ 影响范围约束与风险
  • 关键文件位置。
  • 当前实现现状。
  • 依赖关系。
  • 可直接支撑 PM 或 Builder 决策的证据。

模型建议:默认 gpt-5.4,大规模检索或证据链复杂时切换到 gpt-5.5 medium

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.
