Why use it?
It gives a coding agent the project rules and common commands in one place, reducing setup mistakes and unnecessary searching.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is indragiek/uniprof's own configuration. It tells Claude Code how to work on uniprof itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything uniprof configures →

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

uniprof CLAUDE.md 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 2mo 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.

Uniprof Codebase Guide

Uniprof is a universal profiling tool that wraps platform profilers (py-spy, 0x, rbspy, async-profiler, dotnet-trace, perf, xctrace, etc.) to provide a consistent, cross‑language experience. It prefers Docker to minimize setup and ensure reproducible results.

Quick Start

  • Simplest: profile and analyze in one step
    • uniprof python app.py
    • uniprof --visualize node server.js
  • Save then analyze/visualize later
    • uniprof record -o profile.json -- ./my-app
    • uniprof analyze profile.json
    • uniprof visualize profile.json

CLI Reference

Aliases & Parsing

  • uniprof <cmd> ≈ uniprof record --analyze -- <cmd> (unless --visualize, which maps to record --visualize).
  • Options before the first non‑option belong to uniprof; after, they belong to your command.
  • record inserts -- automatically when omitted (so trailing args reach your app).
  • --extra-profiler-args accepts dashed values directly or as a single quoted string; the alias layer condenses them.

Examples

uniprof python app.py
uniprof -- python app.py
uniprof --visualize -- node server.js
uniprof -o out.json --analyze -- ./my-app

Commands

  • bootstrap — Environment checks and setup guidance
  • record — Record a profile
  • analyze — Analyze an existing profile
  • visualize — Serve the profile in a local Speedscope
  • mcp — Run or install the MCP server

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.
