ctx:researcher

ctx:researcher is a skill for Claude Code from shakestzd/contextune. It costs 69 tokens per session (1,204 once invoked), scanned A, original, MIT.

A research workflow that uses three parallel agents to investigate a topic, tools, libraries, or existing code approaches. It is invoked with the /ctx:research command.

In plain words
What is it for?
Use it to research a topic, compare libraries or tools, evaluate solutions, find similar implementations, or study how a codebase handles a problem.
Why use it?
Parallel investigation gathers web research and codebase patterns in one process, making it easier to compare options and understand adoption or implementation trade-offs.

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

ctx: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 8d 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.

CTX:Researcher Skill

Efficiently research topics using parallel agents via Contextune's /ctx:research command.

When to Activate

This skill should be used when the user:

  • Explicitly mentions: "research", "investigate", "find information about", "look into"
  • Asks comparative questions: "what's the best X for Y?", "compare A and B"
  • Requests library/tool evaluations: "which library should I use?"
  • Wants to understand solutions: "how do other projects handle X?"

What This Skill Does

When activated, this skill executes the /ctx:research command which:

  1. Spawns 3 parallel Haiku agents (~$0.07, 1-2 minutes):

    • Agent 1: Web search for similar solutions and implementations
    • Agent 2: Web search for libraries, tools, and frameworks
    • Agent 3: Codebase pattern analysis (existing approaches)
  2. Returns comprehensive research including:

    • Top 3-5 options with pros/cons
    • Implementation examples
    • Migration/adoption considerations
    • Community adoption and maturity

Workflow

Step 1: Execute the Research Command

/ctx:research [user's query]

Important: Pass the user's query verbatim to capture intent.

Step 2: Wait for Results

The command runs in background. You'll receive results from all 3 agents simultaneously.

Step 3: Synthesize Findings

Present results in this structure:

## Research Findings: [Topic]

### Summary
[1-2 sentence overview of landscape]

### Top Options

#### 1. [Option Name] ⭐ Recommended
- **Pros**: [key advantages]
- **Cons**: [key drawbacks]
- **Best for**: [use cases]
- **Adoption**: [community size, maturity]

#### 2. [Option Name]

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.

ctx:researcher is a skill published in the GitHub repository shakestzd/contextune (5 stars, last pushed 8mo ago), licensed MIT. It adds 69 tokens to every session and 1,204 once invoked, about $0.0003 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 2026-08-31.
