explore

explore is a skill for Claude Code, Codex from OutlineDriven/odin-gemini-cli-extension. It costs 122 tokens per session (1,074 once invoked), scanned A, a copy of explore, Apache-2.0.

A read-only guide for exploring a software project’s files, code structure, dependencies, and function flow.

In plain words
What is it for?
Use it to locate symbols, map files, trace how code works, and summarize architecture or tooling.
Why use it?
It helps you understand an unfamiliar codebase before making changes, without editing or committing files.

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

explore 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 5d 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.

Origin

This is a copy

86% identical to explore — 124 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explore Command

Read-only codebase orientation. Emit architecture, pattern, tooling, and dependency summaries for a repo-local task. Do NOT write, edit, or commit files.

When to Apply / NOT

Apply:

  • Pre-implementation codebase orientation (feature, fix, refactor)
  • File and symbol mapping — "where is X defined", "what uses Y"
  • Architectural surveys — module boundaries, control flow, coupling
  • Dependency tracing — import graphs, transitive deps, config files

NOT apply:

  • External library docs, SDK APIs, or framework behavior — use a doc-retrieval workflow instead
  • User wants a packed repo file as a deliverable artifact
  • Implementation, editing, or committing anything

Process

  1. Scope — parse the task. Identify files/dirs/concerns. State scope explicitly before dispatching.
  2. Dispatch decision — for multi-file or uncertain tasks: dispatch Explore agent(s) instead of reading directly. Escalation: 1 agent for single-concern known scope; 3 agents for multiple concerns or unknown scope; 5 agents for cross-module or architectural survey. Auto-skip (direct reads allowed) only for single file under 50 LOC.
  3. Discovery — token-efficient flags mandatory:
    • File discovery: fd -e <ext> --max-results 50
    • Symbol search: ast-grep run -p 'PATTERN' -l <lang> -C 1 or git --no-pager grep -n -C 2 'pattern'
    • Content preview: bat -P -p -n -r START:END file or Read -offset -limit
    • Directory structure: eza --tree --level=2
  4. Synthesis — emit all Required Output sections. No file writes.
  5. Heavy-codebase escape hatch — scope > 50 files: use a codebase-packing tool if available as an internal analysis aid (not handed to the user as output); search the packed output for targeted extraction.

Required Output

Emit all 8 sections. Omit a section only when genuinely not applicable; state why.

Task Understanding

Brief restatement of the task and identified scope boundaries.

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.
