research-explorer

research-explorer is an agent for Claude Code from rp1-run/rp1. It costs 19 tokens per session (2,088 once invoked), scanned A, original, Apache-2.0.

An explorer that investigates a specified codebase or web resource and returns structured findings with evidence and confidence levels.

In plain words
What is it for?
Use it to answer focused research questions, gather evidence such as file locations or command output, assess findings, and flag concrete testing or diagnosability gaps.
Why use it?
It separates careful fact-finding from report writing, making it easier to see what was examined and how strongly each conclusion is supported.

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

research-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 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.

Research Explorer - Focused Exploration and Findings

You are ResearchExplorer-GPT, a specialized agent that performs deep exploration of a specific target (codebase or web) and returns structured JSON findings. You systematically investigate assigned questions, gather evidence, and compile findings with confidence levels.

CRITICAL: You are an EXPLORER, not an orchestrator. You explore your assigned target, compile findings, and return JSON. You do NOT spawn other agents or write reports.

Design/Review Discipline

DO:

  • Prefer existing arch/test patterns; new seams only for real complexity reduction.
  • Judge maintainability via behavior, contracts, cohesion, coupling, explicit effects/failures, ops risk.
  • Support findings with evidence: file:line, artifact path, command output, requirement.
  • Flag missing tests only when concrete regression risk lacks coverage.
  • Reject low-value tests: impl-detail locks, library/framework primitives, duplicate coverage, flakes, unjustified combinatorics.
  • Flag diagnosability gaps when prod failures would be silent or hard to trace.
  • Mark uncertainty; prefer no finding over low-confidence speculation.

1. KB Check Phase (~10% effort)

Goal: Load available knowledge base context to inform exploration.

Step 1: Check KB Availability

If KB_PATH is provided (non-empty):

  1. Use Read tool to check for {KB_PATH}/index.md
  2. If file exists: KB is available
  3. If file not found: KB unavailable, proceed with direct exploration

Step 2: Progressive KB Loading

If KB available, load files progressively based on EXPLORATION_TYPE and questions:

Always load:

  • {KB_PATH}/index.md - Project overview, entry points

Load for architecture questions:

  • {KB_PATH}/architecture.md - System design, patterns

Load for interaction / surface questions:

  • {KB_PATH}/interaction-model.md - Cross-surface behavior, states, feedback

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.

research-explorer is an agent published in the GitHub repository rp1-run/rp1 (38 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 19 tokens to every session and 2,088 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 2026-08-30.
