Observer Bundle

Real-time AI-powered code review that watches while you work

Status: Unknown
January 2026
The Problem

Code review happens
too late

⏰
Review at PR Time
Traditional code review happens at the end, when context is lost and fixing issues is expensive.
👀
Single Perspective
One reviewer catches one type of issue. Security, architecture, and style need different eyes.
⚡
No Real-Time Feedback
Developers work for hours before discovering issues. Imagine a world where feedback is instant.
The Solution

Expert colleagues
watching in real-time

🔭
Background Observers
Specialized AI agents run in the background during Amplifier sessions, watching file changes and conversations.
📈
Severity-Based Feedback
Issues surfaced from critical to info. Address what matters now, note what can wait.
🎯
Multi-Dimensional Review
Security, architecture, systems thinking, writing quality - reported ~50 specialized perspectives at once.
How It Works

Observer Definition

Simple markdown files with YAML frontmatter. Just like agents, but for background review.

# Security Auditor

You are a security expert reviewing code...
Look for SQL injection, XSS, hardcoded secrets...
The Journey

January 21-26: Reported ~5 days of intensity

1
January 21 - Marathon Begins
~42-turn session reported
Core features emerge rapidly. Semantic deduplication, auto-resolution, and the architecture pivot to bundle-based markdown files.
2
January 22 - Observer Explosion
~50 specialized observers reported
What started as a code reviewer reportedly evolved into comprehensive coverage: security, architecture, systems thinking, communication, and performance.
3
January 22-26 - The Bug Hunt
Systems-thinking debugging
Frustrating bundle loading issues. Created Jupyter notebooks for diagnostics. Discovered sub-bundle metadata requirements through collaborative debugging.
Marathon Sprint

Key pivots in ~42 turns

Duplicate observations - Same issue reported multiple times. Evolved to semantic deduplication using LLM-based similarity detection.
Auto-resolution - Observers now automatically close issues when the underlying problem is fixed. No stale observations.
Architecture pivot - Moved from inline configuration to bundle-based markdown files. Observers defined like agents, in the bundle.
Observer explosion - What started as a code reviewer reportedly became ~50 specialized observers across security, architecture, systems thinking, and more.
The Result
~50

Lessons Learned

Key takeaways

1

Iterative Design

Architecture evolved significantly through real usage. The final design looks nothing like the initial concept.

2

AI-Assisted Debugging

Complex bundle loading issues solved collaboratively with AI. Jupyter notebooks for diagnostics proved invaluable.

3

Scope Evolution

What started as a code observer reportedly became a comprehensive review system spanning security, architecture, and systems thinking.

4

Documentation by Doing

Development sessions serve as living documentation. The conversation history tells the complete story.

Sources & Methodology

How this deck was built

Verification Status
Observer bundle repository could not be located. Claims in this deck are based on session narratives and have not been independently verified against git evidence. Feature status unknown.
Data Sources
Narrative content derived from Amplifier development session logs. Observer counts, timeline dates, and velocity metrics are reported values from session transcripts, not verified against commit history or repository data.
Repository Search
Searched for observer bundle at ramparte/amplifier-bundle-observers and microsoft/amplifier-bundle-observers. Neither location contained a public repository as of the data collection date. No observer-related code was found in amplifier-core or amplifier-foundation.
Methodology
All velocity numbers (days, observer count, session turns) are prefixed with "~" or qualified as "reported" to reflect their unverified status. Architectural descriptions are based on session narrative and may not reflect current implementation.
