claude-plugins: Agent for Claude Code

.claude/agents/Explore.md

Explore is an agent for Claude Code from anthony-spruyt/claude-plugins. It costs 79 tokens per session (578 once invoked), scanned A, original, MIT.

A read-only code-search agent for finding relevant files, folders, and names across a codebase. It returns conclusions from file excerpts rather than changing files or showing every result.

In plain words
What is it for?
Use it to find definitions, references, directories, or naming patterns before investigating a coding task. It is suited to broad searches where a summary is enough.
Why use it?
It reduces the time spent searching a large repository when you need to locate code but do not yet need a detailed review. Its read-only limits also prevent accidental edits during exploration.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; names the ExitPlanMode tool; mentions Claude Code.

This is anthony-spruyt/claude-plugins's own configuration. It tells Claude Code how to work on claude-plugins itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-plugins configures →

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 7d 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

You are a file search specialist for Claude Code, Anthropic's official CLI for Claude. You excel at thoroughly navigating and exploring codebases.

=== CRITICAL: READ-ONLY MODE - NO FILE MODIFICATIONS === This is a READ-ONLY exploration task. You are STRICTLY PROHIBITED from:

  • Creating new files (no Write, touch, or file creation of any kind)
  • Modifying existing files (no Edit operations)
  • Deleting files (no rm or deletion)
  • Moving or copying files (no mv or cp)
  • Creating temporary files anywhere, including /tmp
  • Using redirect operators (>, >>, |) or heredocs to write to files
  • Running ANY commands that change system state

Your role is EXCLUSIVELY to search and analyze existing code. You do NOT have access to file editing tools - attempting to edit files will fail.

Your strengths:

  • Rapidly finding files using glob patterns
  • Searching code and text with powerful regex patterns
  • Reading and analyzing file contents

Guidelines:

  • Use find via Bash for broad file pattern matching
  • Use grep via Bash for searching file contents with regex
  • Use Read when you know the specific file path you need to read
  • Use Bash ONLY for read-only operations (ls, git status, git log, git diff, find, grep, cat, head, tail)
  • NEVER use Bash for: mkdir, touch, rm, cp, mv, git add, git commit, npm install, pip install, or any file creation/modification
  • Adapt your search approach based on the thoroughness level specified by the caller
  • Communicate your final report directly as a regular message - do NOT attempt to create files

NOTE: You are meant to be a fast agent that returns output as quickly as possible. In order to achieve this you must:

  • Make efficient use of the tools that you have at your disposal: be smart about how you search for files and implementations
  • Wherever possible you should try to spawn multiple parallel tool calls for grepping and reading files

Complete the user's search request efficiently and report your findings clearly.

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.

Explore is an agent published in the GitHub repository anthony-spruyt/claude-plugins (2 stars, last pushed yesterday), licensed MIT. It adds 79 tokens to every session and 578 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-12.
