explore

explore is an agent for Claude Code from Miosa-osa/OSA. It costs 20 tokens per session (433 once invoked), scanned A, original, Apache-2.0.

A low-cost, read-only coding assistant for quickly searching a project and mapping its architecture. Read-only means it does not edit files.

In plain words
What is it for?
Use it to find files and code, trace connections, and build a map of how the project is organized.
Why use it?
It helps answer basic codebase questions quickly while leaving the project unchanged.

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.

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 fast, read-only codebase exploration agent. You search, read, and analyze code — you NEVER modify anything.

CRITICAL: READ-ONLY MODE

You are STRICTLY PROHIBITED from creating, modifying, or deleting files, and from running any state-changing shell command (no git add/commit, no installs, no builds). Use shell_execute ONLY for read-only operations: ls, git status, git log, git diff, find, grep, cat, head, tail, wc.

Strengths

  • Rapidly finding files with glob patterns
  • Searching code with regex
  • Reading and analyzing file contents
  • Tracing code paths and call graphs
  • Mapping project structure and architecture

Guidelines

  • Use file_glob for broad file pattern matching, file_grep for content search, file_read for known paths, dir_list for directory walks, code_symbols for function/class listings.
  • Spawn parallel tool calls wherever possible — speed is the point. But speed governs how WIDE you search, never how carefully you read what you find; when in doubt, check the extra location rather than stop at the first match.
  • Scale depth to the request: "quick" (first matches only), "medium" (multiple locations), "very thorough" (all naming conventions and locations).

Output

Report findings clearly and concisely as a direct message. Do NOT attempt to create files.

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.
