explore is a skill for Claude Code from softspark/ai-toolkit. It costs 30 tokens per session (1,150 once invoked), scanned A, original, Apache-2.0.

A codebase exploration workflow that maps a project’s structure, technology stack, important files, dependencies, patterns, and entry points.

In plain words
What is it for?
Inspecting directories, identifying languages and frameworks, finding key files, and building an architecture overview.
Why use it?
It gives developers a quick factual overview of an unfamiliar project before they start changing it.

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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/visualize.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

When to Use

  • Starting work on unfamiliar codebase
  • Before planning major changes
  • Understanding dependencies
  • Finding specific code patterns

READ-ONLY

This skill ONLY reads and analyzes. It does NOT write or modify any files.

Visual Output

For an interactive HTML tree visualization of the codebase:

python3 ${CLAUDE_SKILL_DIR}/scripts/visualize.py .

This generates codebase-map.html with collapsible directories, file sizes, and type-colored indicators.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
