professor-match

professor-match is a skill for Claude Code from xujingchen1996/research-app-toolkit. It costs 54 tokens per session (736 once invoked), scanned A, original, MIT.

A matching guide for finding potential PhD or research-degree supervisors whose work fits your interests and background.

In plain words
What is it for?
Use it to search for supervisors, compare their research areas, judge fit, and set application priorities. It can also add scientific background checks for life-science topics.
Why use it?
It helps narrow a large faculty list into realistic options while considering research fit and your application profile. Strong matches depend on having a CV or other background information.

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

professor-match 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.

Professor Matching

Preconditions

  • Read ../../memory.md first.
  • If there is not yet a CV profile, prioritize suggesting that the user run cv-analyze first, because matching judgments depend on the user's background.

Language Rules

  • Support three output modes: zh, en, and bilingual.
  • If the user explicitly specifies a language, prioritize the current request.
  • Otherwise read preferred_language from memory.md.
  • If it is still unclear, follow the user's current conversation language.
  • Original English proper nouns from professor homepages, school programs, and similar search materials may be retained, but explanatory text should follow the selected output language.

Optional Linkage: Life Science Research

  • If the user's application direction clearly falls under life sciences / biomedical research, such as genetics, functional genomics, immunology, neuroscience, cancer biology, cell biology, or translational medicine, and the current task needs research-direction grounding, then link life-science-research.
  • This is suitable for linkage in scenarios such as:
    • needing to first clarify target / gene / disease / pathway background
    • needing to judge professor fit based on public literature, datasets, or recent research trajectories
    • needing to start from the research-problem space rather than only searching professors by keywords
  • The linkage result should be used primarily to:
    • narrow research keywords
    • judge the natural bridge between the professor's recent work and the user's background
    • identify more specific research-fit narratives
  • If the user only wants routine professor search by school / country / project name, or only wants ranking updates, do not trigger that linkage.

Fill In the Search Conditions First

If the user's request is not specific enough, fill in at least the following information:

  • research direction or keywords
  • target country / region / school scope
  • degree type and enrollment time
  • special constraints, such as "must be recently recruiting students", "prefer industry collaboration", or "want full funding"

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.

professor-match is a skill published in the GitHub repository xujingchen1996/research-app-toolkit (115 stars, last pushed 1mo ago), licensed MIT. It adds 54 tokens to every session and 736 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 2026-08-30.
