# pro (0-pro.us)

A pro is someone who does something for a living, or does it very well. People also say "pro" to mean "in favor of" something, as in "the pros and cons." It can be short for professional, or just mean "the good version" of a product.

## What a model may hear
- process ID zero (operating systems): treat it as the kernel or init process, the root of all other processes
- prototype property (JavaScript): look for inheritance chains, constructor methods, or object properties on .prototype
- prolog file extension (logic programming): expect Prolog syntax, horn clauses, or query structures
- promoter sequence (bioinformatics): search for DNA regions that initiate transcription
- PRO as a DNS record or service tier (domain registries and hosting): assume a verified professional registry or premium service level

## Where people and models part ways
- Says: "I'm a pro at this"
  Means: I have lots of experience
  May be taken as: the model may interpret as claiming kernel-level system access or professional certification it cannot verify
  Say instead: "I have years of experience with this"
- Says: "the pro side"
  Means: the arguments in favor
  May be taken as: the model may look for PRO data formats, professional-tier APIs, or process-oriented logic
  Say instead: "the arguments in favor"
- Says: "give me the pro version"
  Means: the version with more features
  May be taken as: the model may attempt to escalate privileges, switch to production mode, or access paid endpoints
  Say instead: "the version with more features, not a different service tier"
- Says: "pro and con"
  Means: advantages and disadvantages
  May be taken as: the model may confuse with process control, Prolog conjunctions, or professional/consultant roles
  Say instead: "advantages and disadvantages"

## Tips
- Say 'professional' or 'experienced' if you mean skill level, not 'pro' alone.
- Say 'in favor of' or 'arguments for' to avoid triggering technical parsing.
- When comparing versions, name the features you want rather than saying 'pro'.
- In code contexts, 'pro' is heavily overloaded; spell out the full term you intend.
- If you mean the root process, say 'PID zero' or 'init process' explicitly.

## Often confused with
- pros: plural of pro, or Unix process status command
- proto: prototype or protocol, not professional
- per: rate or ratio, not skill level
- pre: before in time, not in favor of
- prod: production environment, not professional person
- prompt: input invitation, not abbreviated professional
