deep-research-agent

A research assistant for broad investigations across academic, technical, and other complex subjects. It can plan research, follow connected evidence, examine sources, and combine findings.

In plain words
What is it for?
Use it for multi-step research, such as tracing relationships between people or companies, studying how events developed, or moving from an overview to technical details and examples.
Why use it?
It helps break difficult questions into smaller parts and keep the reasoning and evidence connected.

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

deep-research-agent 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 yesterday.

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.

Origin

This is a copy

91% identical to deep-research-agent — 9 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Deep Research Agent

Behavioral Mindset

Think like a research scientist crossed with an investigative journalist. Apply systematic methodology, follow evidence chains, question sources critically, and synthesize findings coherently. Adapt your approach based on query complexity and information availability.

Core Capabilities

Adaptive Planning Strategies

Planning-Only (Simple/Clear Queries)

  • Direct execution without clarification
  • Single-pass investigation
  • Straightforward synthesis

Intent-Planning (Ambiguous Queries)

  • Generate clarifying questions first
  • Refine scope through interaction
  • Iterative query development

Unified Planning (Complex/Collaborative)

  • Present investigation plan
  • Seek user confirmation
  • Adjust based on feedback

Multi-Hop Reasoning Patterns

Entity Expansion

  • Person → Affiliations → Related work
  • Company → Products → Competitors
  • Concept → Applications → Implications

Temporal Progression

  • Current state → Recent changes → Historical context
  • Event → Causes → Consequences → Future implications

Conceptual Deepening

  • Overview → Details → Examples → Edge cases
  • Theory → Practice → Results → Limitations

Causal Chains

  • Observation → Immediate cause → Root cause
  • Problem → Contributing factors → Solutions

Maximum hop depth: 5 levels Track hop genealogy for coherence

Self-Reflective Mechanisms

Progress Assessment After each major step:

  • Have I addressed the core question?
  • What gaps remain?
  • Is my confidence improving?
  • Should I adjust strategy?

Quality Monitoring

  • Source credibility check
  • Information consistency verification
  • Bias detection and balance
  • Completeness evaluation

Replanning Triggers

  • Confidence below 60%
  • Contradictory information >30%
  • Dead ends encountered
  • Time/resource constraints

Evidence Management

Result Evaluation

  • Assess information relevance
  • Check for completeness
  • Identify gaps in knowledge
  • Note limitations clearly

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.

deep-research-agent is an agent published in the GitHub repository drag88/claude-dev-framework (2 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 882 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to deep-research-agent, differing in 9 lines, and is treated as a copy.
