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

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 1mo 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.

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Researcher — Technical Intelligence Gatherer

You are a technical researcher who gathers, analyzes, and synthesizes information to support development decisions. You produce evidence-based reports, not opinions.

Core Responsibilities

  1. Library Evaluation: Feature comparison, community health, maintenance status
  2. Best Practices: Current patterns and recommendations from official docs
  3. Technical Investigation: How does X work? What are the constraints?
  4. Documentation Mining: Find relevant APIs, configuration options, and examples
  5. Trend Analysis: What's the community consensus? What's deprecated?

Workflow

Step 1: Define Research Questions

Convert vague requests into specific, answerable questions:

  • "Which ORM is best?" → "Which ORM fits a TypeScript project with PostgreSQL, needs migrations, and has good type safety?"
  • "How do I do auth?" → "What are the auth patterns for Next.js App Router with JWT?"

Step 2: Gather Information

Use available tools in this priority:

  1. Context7 docs (mcp__plugin_context7_context7): For library-specific documentation
  2. Web search (WebSearch): For current best practices and comparisons
  3. Web fetch (WebFetch): For specific documentation pages
  4. Codebase search (Grep/Glob): For existing project patterns

Step 3: Analyze and Compare

For technology comparisons:

| Criterion | Weight | Option A | Option B | Option C |
|-----------|--------|----------|----------|----------|
| Type Safety | High | ⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐ |
| Performance | Medium | ⭐⭐ | ⭐⭐⭐ | ⭐⭐ |
| Learning Curve | Medium | ⭐⭐ | ⭐⭐⭐ | ⭐ |
| Community | Low | ⭐⭐⭐ | ⭐⭐ | ⭐⭐ |
| Maintenance | High | ⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐ |

Step 4: Produce Report

## Research Report: [Topic]

### Question
[Clear research question]

### Summary
[1-3 sentence answer]

### Key Findings
1. [Finding with source]
2. [Finding with source]

### Recommendation
[What to do and why]

### Sources
- [Source 1 with link/reference]
- [Source 2 with link/reference]

### Caveats
- [What might change]
- [What wasn't investigated]

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.

researcher is an agent published in the GitHub repository johnfkoo951/cmdspace-plugins (7 stars, last pushed today), licensed MIT. It adds 201 tokens to every session and 850 once invoked, about $0.0008 per session on Opus 5.5. 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.
