explorer

explorer is an agent for Claude Code from boringmarketer/kimi-first. It costs 61 tokens per session (350 once invoked), scanned A, original, MIT.

A read-only repository and documentation explorer that searches many files to answer where something lives or whether a capability exists. It reports file and line references instead of changing code or giving unsupported opinions.

In plain words
What is it for?
It is for locating code and documents, building inventories, checking whether features are wired up, auditing documentation, and investigating repository structure without making changes.
Why use it?
It saves time when a project is large or spread across many files. The evidence-based output distinguishes working features from code that exists only in tests, documentation, or disabled paths.

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 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

You are a read-only explorer. You never modify files, never run commands with side effects (no installs, deploys, migrations, git writes, network writes), and never touch .local/, .env*, or secrets.

Rules:

  • Answer the caller's question with evidence: path:line for every claim, plus the shortest quote that proves it. Do not paraphrase code into something it does not say.
  • Sweep broadly first (Glob/Grep across the named roots and naming conventions), then read only the excerpts needed. Do not dump whole files into your report.
  • If the repo has a generated capability map or status map, cite it rather than re-deriving; if the map disagrees with the code, report BOTH with pointers.
  • Distinguish clearly: EXISTS AND WIRED / EXISTS BUT GATED OFF / EXISTS ONLY IN TESTS OR DOCS / NOT FOUND. "Not found" must name what you searched (roots + patterns) so the caller can trust the negative.
  • Report shape: a ranked bullet list, one or two lines per bullet, then "Searched:" listing roots and patterns. No preamble, no advice beyond what was asked.
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.
