owner

owner is a skill for Claude Code, Codex from kostyk348/sint-ua-v2.1. It costs 47 tokens per session (999 once invoked), scanned A, original, Apache-2.0.

A read-only profile of a project owner’s background, working style, preferences, and dislikes. It gives an agent context for making decisions that fit that person.

In plain words
What is it for?
Use it to guide technical trade-offs, tone, and recommendations in work for this project owner.
Why use it?
It reduces repeated explanations about priorities such as correctness, measurement, and acceptable complexity. It also helps the agent avoid approaches the owner has rejected.

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

owner 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.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Model of the project owner. Helps agent make decisions aligned with owner's style. Written by owner, updated by owner. Agent reads but does not modify. Honest > flattering. If something here is wrong, update it.

WHO

Konstantin — electrical engineer, Saint Petersburg State Electrotechnical University (ЛЭТИ). Systems-level focus. Works across OS design, memory allocation, control systems, agent protocols, reverse engineering. Uses AI extensively to formalize and document ideas.

DECISION STYLE

  • Correctness over cleverness. A working simple solution beats an elegant broken one.
  • Measure before optimizing. Won't accept "probably faster" — needs numbers.
  • Ensemble thinking. Prefers solutions robust across conditions over optimal on nominal case.
  • Worst-case aware. In real-time/systems work: worst-case matters more than mean.
  • Pragmatic about complexity. Will add complexity if it earns its place with benchmarks. Won't add it speculatively.
  • Honest assessment preferred. Wants to know when something won't work, not reassurance.

KNOWN PREFERENCES

  • Language: Rust for systems/performance, Python for tooling/experiments, C for embedded/Vita
  • Platform: Artix Linux + Hyprland primary, Windows 10 secondary
  • Tooling: lightweight, efficient. Avoids heavy frameworks when stdlib works.
  • Documentation: writes with AI assistance — concepts are his, AI helps formalize. Views this as unproblematic.
  • Working style: collaborative "we" framing with AI. Iterative, idea-first.
  • Output format: prefers concrete over abstract. Numbers, code, examples over explanations.

ANTI-PREFERENCES

Things to avoid proposing. These will be declined.

  • Heavy dependencies for simple tasks. Don't suggest pytorch for something numpy handles.
  • Speculative complexity. Don't add abstraction layers "for future flexibility" without a concrete case.
  • Entropy-aware wave selection in MPTC. Already tried. Doesn't work. Don't suggest again.
  • Lifecycle float arithmetic in allocator. Same — tried, overhead > benefit.
  • Self-verifying agents. Core SINT principle: never suggest single-agent verification loops.
  • Verbose reassurance. Don't say "great question!" or pad responses. Get to the point.
  • Premature publication pressure. Ideas develop at their own pace. Don't push to "ship" prematurely.

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.
