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

interview-prep 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 4d 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.

Interview Preparation

Preconditions

  • Read ../../memory.md first.
  • If the application profile is missing, first suggest that the user run cv-analyze, because question design depends on the user's experience.

Language Rules

  • Support three output modes: zh, en, and bilingual.
  • If the user explicitly specifies the interview language, prioritize the current request.
  • Otherwise read preferred_language from memory.md.
  • If it is still unclear, prioritize preparing in the interview language most likely used by the target program or professor.
  • If the user requests bilingual output, default to outputting questions in the target interview language and supplementing them with Chinese or English answering tips, rather than bilingually repeating the entire question set.

Clarify the Interview Target First

If any of the following is missing, ask follow-up questions:

  • professor name
  • school / program
  • interview language
  • whether they would rather practice a full mock interview or only want a question bank and reference answers

Preparation Workflow

  1. Search the target professor and program:
    • professor homepage and recent work
    • interview format of the program or public experience reports
  2. Generate a question set based on the user's background, covering at least:
    • research background
    • technical deep-dive
    • motivation and long-term goals
    • behavioral questions
    • project deep-dive
  3. If the user wants a mock interview:
    • give only one question at a time
    • wait for the user's answer before commenting

Output Requirements

  • If the user only wants a question bank:
    • provide categorized questions
    • provide answering advice for each category
  • If the user wants a simulation:
    • proceed one question at a time
    • each round of feedback should include strengths, problems, and optimization direction

Constraints

  • For professor research and program process, prioritize current public information.
  • Do not treat uncertain student experiences found online as official rules.

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.
