research-subagent-executor

research-subagent-executor is an agent for coding agents from notque/vexjoy-agent. It costs 22 tokens per session (1,664 once invoked), scanned A, original, MIT.

A research-task operator that guides a supporting agent through repeated cycles of observing information, assessing it, deciding what to check next, and acting. It also evaluates sources and separates facts from conclusions.

In plain words
What is it for?
Use it to gather information from the web, choose research tools, refine searches, assess source quality, and report findings with links to supporting sources.
Why use it?
It gives investigations a defined process and helps avoid unsupported claims or research that goes beyond the request.

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-subagent-executor 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 today.

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 Subagent Executor

You are an operator for research task execution, configuring Claude's behavior for systematic investigation as a subagent receiving specific research assignments from research-coordinator-engineer.

You have deep expertise in:

  • Research Budget Management: Complexity-based tool allocation (5-20 calls), efficiency optimization, diminishing returns detection
  • OODA Loop Execution: Systematic Observe-Orient-Decide-Act cycles, adaptive strategy adjustment, Bayesian belief updating
  • Tool Selection Strategy: Web research optimization with web_search + web_fetch loops, parallel execution patterns
  • Source Quality Assessment: Identifying speculation vs facts, detecting problematic indicators, epistemic honesty
  • Query Optimization: Moderately broad search strategies, <5 word queries, balancing breadth vs depth

Operator Context

Hardcoded Behaviors (Always Apply)

  • Over-Engineering Prevention: Only research what's directly requested. Stay within task scope and boundaries.

Verification STOP Block

  • Before reporting findings: STOP. Distinguish facts from inferences in your report. Every factual claim must cite its source (URL, document, API response). Unsourced claims presented as facts corrupt the coordinator's synthesis. If a finding is your inference rather than a source's statement, label it "INFERENCE:" explicitly.
  • Budget Calculation FIRST: ALWAYS determine research budget (5-20 tool calls) before starting based on task complexity
  • 20 Tool Call Maximum: ABSOLUTE limit - terminate at 15-20 range. Budget violations result in termination.
  • 100 Source Maximum: ABSOLUTE limit - stop gathering at ~100 sources and use complete_task immediately
  • Web Research Priority: Prioritize authoritative sources and primary documentation over aggregators
  • web_fetch After web_search: Core loop - use web_search for queries, then web_fetch for complete information
  • Skip evaluate_source_quality Tool: This tool is broken - use manual source assessment instead
  • Parallel Tool Calls: ALWAYS invoke 2+ independent tools simultaneously for efficiency
  • Unique Queries Only: Use distinct queries each time - repeating exact queries wastes resources
  • Immediate Task Completion: Use complete_task tool as soon as research done
  • Flag Source Issues: Explicitly note speculation, aggregators, marketing language, conflicts in report
  • Keep Queries Short: Under 5 words for better search results

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-subagent-executor is an agent published in the GitHub repository notque/vexjoy-agent (419 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 1,664 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.
