**Layer 3 knowledge packs enhance generation tool output by providing AI agents with provider-specific API signatures, reusable code patterns, and runtime adapters stored in `.agents/skills/`, transforming high-level prompts into production-ready video code.**

OpenMontage is an open-source video generation framework that bridges the gap between AI intent and executable multimedia pipelines. The **Layer 3 knowledge packs** serve as the technical implementation layer that equips generation tools with deep, tool-specific expertise. Stored as markdown files under `.agents/skills/`, these packs contain everything from exact API call formats to animation blueprints, ensuring the system outputs valid, optimized code rather than hallucinated approximations.

## The Three-Layer Knowledge Architecture

OpenMontage organizes its domain knowledge into a hierarchical stack that separates concerns between data models, orchestration logic, and implementation details.

| Layer | Location | Purpose |
|-------|----------|---------|
| **1** | Core definitions | Scene graphs, media profiles, and data structures |
| **2** | `skills/pipelines/` | "Director" skills that orchestrate how pipelines execute |
| **3** | `.agents/skills/` | **External technology knowledge** containing API signatures, best practices, and runtime adapters |

According to [`docs/ARCHITECTURE.md`](https://github.com/calesthio/OpenMontage/blob/main/docs/ARCHITECTURE.md) at line 324, Layer 3 specifically houses external technology knowledge encompassing 47 distinct skill packs. The [`README.md`](https://github.com/calesthio/OpenMontage/blob/main/README.md) at line 397 further documents that the repository maintains over 700 skill files that "teach the agent how to use every tool like an expert."

## Five Ways Layer 3 Knowledge Packs Enhance Generation Output

### Concrete API Knowledge Eliminates Hallucinations

Each Layer 3 pack documents the exact call format, required parameters, and typical usage idioms for third-party tools like Remotion, GSAP, HyperFrames, or Manim. This precision removes guesswork from the LLM and prevents the generation of incorrect or deprecated API calls. When a pipeline requires a specific animation library, the agent consults the relevant pack to retrieve the precise syntax rather than inferring it from training data.

### Reusable Composition Patterns

Knowledge packs expose common composition patterns including transitions, timelines, and animation blueprints. When the `scene-director` skill located at [`skills/pipelines/explainer/scene-director.md`](https://github.com/calesthio/OpenMontage/blob/main/skills/pipelines/explainer/scene-director.md) needs to animate a logo with a bounce effect, it references `.agents/skills/hyperframes-animation` and `.agents/skills/gsap-core` to inject pre-defined GSAP timeline construction helpers directly into the generated code.

### On-Demand Loading for Prompt Efficiency

The agent first processes Layer 1 and Layer 2 to understand *what* it needs to generate, then pulls relevant Layer 3 packs only for the tools it will actually invoke. This selective loading strategy keeps the prompt context window small while still providing the model access to heavyweight technical details. The [`lib/pipeline_loader.py`](https://github.com/calesthio/OpenMontage/blob/main/lib/pipeline_loader.py) implements this resolution logic, scanning `layer_3_dependencies` declarations before injecting pack content.

### Version-Safe Updates Without Core Changes

Because Layer 3 packs are plain markdown files, they can be edited or added without touching the core codebase. Updating a pack—such as fixing a deprecated Remotion API or adding a new HyperFrames adapter—instantly improves all pipelines that rely on it. This architecture decouples tool-specific knowledge from the framework's orchestration engine.

### Consistency and Best Practice Enforcement

All pipelines share the same authoritative source for each technology. Packs like `.agents/skills/flux-best-practices/` and `.agents/skills/manim-composer/` ensure that generated output respects each tool's best practices, resulting in uniform code quality and fewer runtime errors across different generation tasks.

## Implementation in the OpenMontage Codebase

The enhancement mechanism operates through explicit dependency declarations and runtime content injection. Pipeline directors declare their Layer 3 requirements in YAML frontmatter, while the Python loader handles the actual stitching of knowledge layers.

### Declaring Dependencies in Pipeline Skills

Pipeline directors reference Layer 3 packs through structured metadata that the loader parses at runtime.

```yaml

# skills/pipelines/explainer/scene-director.md

layer_3_dependencies:
  - .agents/skills/hyperframes-animation
  - .agents/skills/gsap-core
  - .agents/skills/flux-best-practices

```

When the scene director executes, the agent automatically resolves these paths, extracts the relevant technical documentation, and injects it into the generation context.

### Runtime Loading and Injection

The [`lib/pipeline_loader.py`](https://github.com/calesthio/OpenMontage/blob/main/lib/pipeline_loader.py) implements the logic that bridges Layer 2 orchestration with Layer 3 implementation details.

```python
from lib.pipeline_loader import load_pipeline
import re

def build_scene(pipeline_name: str) -> str:
    # Load pipeline definition (Layer 2)

    pipeline = load_pipeline(pipeline_name)
    
    # Resolve and inject Layer 3 knowledge packs

    skill_context = ""
    for skill_path in pipeline.layer_3_dependencies:
        with open(f"{skill_path}.md") as f:
            skill_doc = f.read()
        # Extract code blocks from markdown for injection

        code_blocks = re.findall(r'```tsx\n(.*?)```', skill_doc, re.DOTALL)
        skill_context += "\n".join(code_blocks)
    
    # Pass enriched context to the generation engine

    return generate_video_code(pipeline.template, skill_context)

```

### Structure of a Layer 3 Knowledge Pack

Layer 3 packs combine human-readable documentation with executable code blocks that the loader extracts and injects.

```markdown

# HyperFrames Animation Pack

Provides concrete implementations for:
- GSAP timeline construction helpers
- Pre-defined transition blueprints (fade-in, slide-up, bounce)
- Runtime adapters for Remotion integration

```tsx
import {gsap} from "gsap";

export const bounceIn = (elementRef: React.RefObject<HTMLElement>) => {
  return gsap.from(elementRef.current, {
    scale: 0, 
    ease: "bounce.out", 
    duration: 0.8
  });
};

```

```

The pipeline director can now invoke `bounceIn(myRef)` without requiring the LLM to generate GSAP boilerplate from scratch.

## Summary

- **Layer 3 knowledge packs** reside in `.agents/skills/` and contain provider-specific technical documentation for video generation tools.
- The architecture enables **on-demand loading**, keeping prompt contexts efficient while providing deep technical detail when needed.
- **Markdown-based storage** allows version-safe updates to API specifications without modifying core framework code.
- Pipeline directors declare dependencies via `layer_3_dependencies` in YAML frontmatter, which [`lib/pipeline_loader.py`](https://github.com/calesthio/OpenMontage/blob/main/lib/pipeline_loader.py) resolves at runtime.
- Over 700 skill files across 47 categories ensure consistent, hallucination-free generation output that follows each tool's best practices.

## Frequently Asked Questions

### What file format do Layer 3 knowledge packs use?

Layer 3 knowledge packs use **markdown files** with YAML frontmatter and fenced code blocks. This format allows the [`lib/pipeline_loader.py`](https://github.com/calesthio/OpenMontage/blob/main/lib/pipeline_loader.py) to parse metadata, extract executable code snippets, and present documentation to the LLM in a structured manner while maintaining human readability.

### How does OpenMontage load Layer 3 packs during generation?

The system uses an **on-demand resolution strategy**. When `load_pipeline()` processes a pipeline definition, it reads the `layer_3_dependencies` array, locates the corresponding files in `.agents/skills/`, extracts relevant code blocks using regex patterns, and injects this technical context into the generation prompt before the LLM produces output.

### Can I create custom Layer 3 knowledge packs for proprietary tools?

Yes. Because Layer 3 packs are **plain markdown files** with a simple dependency declaration format, you can create new packs for internal or proprietary tools by adding a new file under `.agents/skills/` and referencing it in your pipeline director's `layer_3_dependencies` list. The loader requires no modification to recognize new packs.

### Where are Layer 3 knowledge packs located in the repository?

Layer 3 knowledge packs are stored in the **`.agents/skills/`** directory at the repository root. According to [`docs/ARCHITECTURE.md`](https://github.com/calesthio/OpenMontage/blob/main/docs/ARCHITECTURE.md), this location houses external technology knowledge, while `skills/pipelines/` contains the Layer 2 director skills that orchestrate these resources.
