Key Features

• One‑line instrumentation – decorate any function with @info_decorator to capture its implementation, arguments, return value, runtime, exceptions, and more, both statically & dynamically.
• Project‑wide tracing – vibetracer run path/to/main.py auto‑instruments every in‑house function (external packages are ignored) and stores rich execution data in a local SQLite DB.
• LLM‑powered analysis – vibetracer analyze turns raw traces into two Markdown reports: human‑readable and LLM‑ready. Plug in Anthropic, OpenAI, or Google with your API key for a full audit.
• Actionable insights – Errors, security issues, performance hotspots, resource concerns, and architectural notes – each with concrete suggestions.
• All‑local, zero infra – no remote telemetry, no servers to run, API keys never leave your machine (check the source!).
• One‑shot convenience – vibetracer runalyze runs & analyzes in a single command.

---

Quick Start

1· Decorator‑level tracing

from vibetracer import info_decorator


@info_decorator
def greet(name: str) -> str:
    return f"Hello, {name}!"


print(greet("Vibe coder"))

After execution you’ll find an execution_<timestamp>.db SQLite file in .vibetracer/.

2· Project‑wide tracing

vibetracer run path/to/main.py

3· AI‑assisted analysis

export LLM_PROVIDER=openai   # or anthropic / google
export {LLM_PROVIDER}_API_KEY=<your‑LLM-provideer-api‑key>

vibetracer analyze .vibetracer/execution_latest.db

4· All‑in‑one

vibetracer runalyze path/to/main.py --provider='openai' --api_key=$OPENAI_API_KEY

Command‑line Reference

Command	Purpose	Required Arg	Optional Flags / Env Vars
vibetracer run	Trace an entire project	Path to entry main.py	–
vibetracer analyze	Analyze a trace DB	Path to .db file or folder (picks latest)	--provider (openai/anthropic/google, default openai) or LLM_PROVIDER, --api_key or {LLM_PROVIDER}_API_KEY
vibetracer runalyze	Run + analyze in one go	Path to entry main.py	Same as analyze

ℹ️ API keys stay local – they are only used to call the selected provider from your machine.

---

Generated Reports

Each analysis produces two Markdown files:

1. Human Report – readable, annotated summary of runtime findings.
2. LLM Report – structured, token‑balanced context ready for further prompts.

Both contain five sections:

Section	Description
Errors & Exceptions	Runtime failures + fixes
Security Issues	Potential vulnerabilities + mitigations
Performance Hotspots	Slow spots + optimization ideas
Runtime Concerns	Memory / I/O / resource notes
Architectural Notes	Organization & best‑practice suggestions

Paste either report into your favourite chat‑GPT‑like tool to continue iterating – or just read it yourself.

Check out this sample report from a real project vibe traced using vibetracer.

Installation

pip install vibetracer

---

Configuration

Env Var	Purpose	Default
LLM_PROVIDER	LLM provider (openai, anthropic, google)	openai
{LLM_PROVIDER}_API_KEY	API key for provider	–

Config can also be given via CLI flags (see above). CLI flags override env vars.

---

Security & Privacy

• Local‑first: All traces & analysis stay on disk – no external telemetry.
• Transparent: Open‑source code – verify what happens with your data.
• Ephemeral keys: API keys are read once, kept in memory, never stored.
