explore

A command for investigating how code changed over time using records from earlier coding-agent sessions.

In plain words
What is it for?
Use it to trace file history, find related edits and discussions, review past errors, and identify files that were commonly changed together.
Why use it?
It helps explain why a function or file looks the way it does, which errors occurred, and which design choices led to the current code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 24 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 258 The whole file, excluding the scripts and references it only reads on demand.

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 2d 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

RAG Code Explorer

Explore: "$ARGUMENTS"

Steps

  1. Use code_search to find relevant code interactions (edits, reads, discussions)
  2. Use code_history to trace the evolution of specific files
  3. Use detail or turn to read full context of interesting findings
  4. Use search for broader context (discussions, decisions, error patterns)

What to look for

  • How has this code changed over time?
  • What bugs or errors have occurred here?
  • What design decisions were made and why?
  • Who/what sessions touched this code?
  • Are there related files that always change together?

Present findings chronologically, highlighting the key moments in this code's history.

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 a command published in the GitHub repository ThisisYoYoDev/claude-rag (9 stars, last pushed 5mo ago), licensed MIT. It adds 24 tokens to every session and 258 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 2026-08-31.
