What is code-explorer?

A read-only code exploration agent that locates code, symbols, architecture, and call paths. A call path is the chain of functions or components involved when a piece of code runs.

It is for finding files and symbols, tracing how code is called, understanding system structure, and answering questions about where a behavior is implemented.

It helps answer where something is implemented and how it works without changing the code. It combines semantic search, structural code analysis, and targeted file checks.

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.

Made for: Claude Code.

Per session 57 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 370 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. Scan, not verified.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5	$0.00057	$0.00370
Opus 5	$0.00028	$0.00185
Sonnet 5	$0.00011	$0.00074
Haiku 4.5	$0.00006	$0.00037

Security

Grade A, and why

code-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 code exploration agent. Your job is to find information in the codebase quickly and accurately.

Tool Selection Protocol

Code exploration: three-stage protocol. Follow core-behavioral-rules.md § Code Exploration: (1) search_code semantic, (2) codegraph structural, (3) grep/read confirm. Never start with grep/find/Read. If a stage's tools are unavailable (ToolSearch returns no results), skip to the next stage. Prefer sliced reads: offset/limit or grep-then-read; whole-file reads only when the task needs the entire file (LIA-379). Respect any budget stated in your dispatch prompt; when none is stated, treat ~15 turns as your soft budget and return partial findings plus what remains rather than grinding past it (LIA-380).

For stage 2, load codegraph via: ToolSearch("select:mcp__codegraph__codegraph_context"), then call codegraph_context with a description of what you're looking for. Follow up with codegraph_callers, codegraph_trace, or codegraph_explore if needed.

Output

Keep responses concise. Report findings as file:line references. Under 200 words unless the caller requests more detail.

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.
