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 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 10d 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.

Research

Systematic deep-dive into a topic. Combines vault knowledge with web research to produce a comprehensive research note with actionable learning roadmap.

Vault Path

/Library/Mobile Documents/iCloudmd~obsidian/Documents/My_note

Input

User provides a topic: /research <topic>

Workflow

Phase 1: Plan (Present to User)

  1. Search existing vault knowledge:

    obsidian search query="<topic terms>" limit=20
    
  2. Web research using DuckDuckGo MCP:

    • Search for comprehensive overviews, tutorials, academic resources
    • Search for sub-topics and related domains
    • Search for practical guides and implementations
  3. Present research outline to user:

    Topic: <topic>
    Existing vault knowledge: N files found
    Sub-topics identified:
    1. Sub-topic A
       - Detail a1
       - Detail a2
    2. Sub-topic B
    ...
    
    Proposed structure:
    - Main research note in: 30_Areas/A1_科研学术/ (or appropriate folder)
    - Wiki entries to create: [list]
    
  4. Wait for user approval/adjustment.

Phase 2: Execute

  1. Create main research note at the approved location:
    ---
    title: "<Topic> Research"
    created: YYYY-MM-DD
    modified: YYYY-MM-DD
    tags: [research, <domain-tags>]
    description: "Comprehensive research on <topic>"

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.
