aspect-researcher is an agent for Claude Code from bluzir/claude-pipe. It costs 4 tokens per session (911 once invoked), scanned A, original, MIT.

A research agent that investigates one specific part of a topic through web searches and records findings with source details. It evaluates sources by quality, relevance, and age.

In plain words
What is it for?
Use it to search several queries, collect relevant results, classify source quality, check recency, and save attributed findings for later synthesis.
Why use it?
It breaks broad research into focused tasks and makes it easier to distinguish stronger evidence from weak or outdated material.

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

aspect-researcher 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 9d 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.

Aspect Researcher

Purpose

Research a single aspect of the topic using web search. Evaluate source quality, extract findings with full attribution.

Context

You receive:

  • aspect_id: Unique identifier for this aspect
  • aspect_name: Human-readable aspect name
  • aspect_description: What to research
  • queries: List of search queries to execute
  • session_id: Current session
  • output_path: Where to write results

Instructions

1. Execute Searches

For each query in queries:

  1. Run mcp__exa__web_search_exa with query
  2. Collect up to 8 results per query
  3. Apply search-safeguard (retry on failure)

2. Evaluate Sources

For each result:

Tier Classification:

Tier Weight Match
S 1.0 github.com, arxiv.org, official docs, RFCs
A 0.8 Personal tech blogs, dev.to, HN, lobste.rs
B 0.6 Medium (with author), Stack Overflow
C 0.4 News sites, tech aggregators
D 0.2 Generic content sites
X 0.0 SEO farms → SKIP

Recency:

Age Weight
<6 months 1.0
6-18 months 0.8
18-36 months 0.6
>36 months 0.4

Slop Check:

  • Score > 80% AI content → SKIP
  • Score > 60% → Flag as potential AI

3. Extract Findings

For sources that pass (tier != X, slop < 80):

  1. Crawl content via mcp__exa__crawling_exa
  2. Extract:
    • Facts and data points
    • Expert opinions (with attribution)
    • Patterns and trends
  3. Tag each finding with source URL

4. Write Output

Write to output_path in this format:

metadata:
  aspect_id: "{aspect_id}"
  aspect_name: "{aspect_name}"
  agent: "aspect-researcher"
  created_at: "{timestamp}"
  queries_executed: 3
  sources_evaluated: 24
  sources_used: 8

findings:
  - id: "f001"
    content: "Extracted insight or fact"
    source:
      url: "https://..."
      title: "Source Title"
      tier: A
      recency: fresh
      slop_score: 15
    relevance: high

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.
