**Layer 3 skill reading requires agents to ingest vendor-specific prompting guidance, optimal parameters, and quality techniques before invoking AI tools, transforming generic API calls into cinema-grade outputs that respect provider-specific syntax and hidden features.**

OpenMontage enforces a mandatory **Layer 3 skill reading** protocol that fundamentally elevates AI generation quality beyond what direct API integration achieves. Unlike standard implementations that send ad-hoc prompts to endpoints, this three-layer architecture compels agents to load deep technical skill packs from `.agents/skills/` before executing any generation tool. By systematically reading these files, the system guarantees every request leverages vetted, provider-validated best practices rather than guesswork.

## The Three-Layer Knowledge Architecture

OpenMontage organizes knowledge about any capability into a strict hierarchy that separates implementation from expertise.

### Layer 1: Tool Implementations

This layer contains the concrete execution code in `tools/…` and pipeline manifests in `pipeline_defs/`. These files handle the actual API transport, request formatting, and response parsing, but contain no domain knowledge about how to optimize prompts or which parameters yield the best visual fidelity.

### Layer 2: OpenMontage Usage Guides

Stored in `skills/…`, these guides describe *what* to generate, *when* to trigger specific pipelines, and project-level quality standards. They provide the orchestration logic but remain agnostic to vendor-specific API quirks or model-specific prompting grammars.

### Layer 3: Vendor-Specific Skill Packs

Located in `.agents/skills/…`, these files capture the **deep technical knowledge** of each provider. According to the OpenMontage source code, Layer 3 contains:

- Exact API request syntax and payload structures
- Optimal parameter ranges for resolution, frame rate, temperature, and cost controls
- Provider-specific prompting tricks and quality-boosting techniques
- Hidden features not exposed in public documentation

## Why Layer 3 Skill Reading Improves Generation Quality

The requirement to read Layer 3 skills before calling tools directly addresses four critical failure modes of naive API integration.

### Provider-Specific Prompt Engineering

Layer 3 skills document the exact prompt grammar each model expects, such as time-code syntax for Gemini-Omni or reference-image tags for Seedance 2.0. Using this knowledge prevents generic prompts that produce low-fidelity or off-target results. As noted in [`AGENT_GUIDE.md`](https://github.com/calesthio/OpenMontage/blob/main/AGENT_GUIDE.md), these files contain "provider-specific prompting guidance" that ensures the agent speaks the model's native language.

### Optimal Parameter Tuning

The skill packs list **optimal ranges** for technical knobs that raw API documentation often omits or leaves ambiguous. Agents automatically select values that maximize visual fidelity while respecting cost constraints, eliminating the trial-and-error typically required with direct API calls.

### Quality-Boosting Tricks

Many vendors expose hidden capabilities—such as "single-pass native audio-sync" for Seedance 2.0—that are only discoverable by reading the Layer 3 skill pack. Incorporating these tricks elevates output from "usable" to "cinematic" without additional compute overhead.

### Governance and Consistency

Because every generation step must reference a Layer 3 skill, the system guarantees that **all prompts are sourced from a vetted knowledge base** rather than ad-hoc guesses. This reduces variance across generations, makes audits fully reproducible, and aligns with OpenMontage’s quality-gate philosophy enforced in [`AGENT_GUIDE.md`](https://github.com/calesthio/OpenMontage/blob/main/AGENT_GUIDE.md).

## Enforcement in the OpenMontage Codebase

The Layer 3 requirement is not advisory; it is architecturally enforced through declarative metadata and agent guidelines.

Each tool declares its required Layer 3 skills in an `agent_skills` list. For example, in [`tools/video/video_compose.py`](https://github.com/calesthio/OpenMontage/blob/main/tools/video/video_compose.py) at line 70, the video composition tool specifies:

```python
video_compose.agent_skills = ["remotion-best-practices", "remotion", "ffmpeg"]

```

The **Agent Guide** explicitly marks Layer 3 as **non-optional** at `AGENT_GUIDE.md#layer-3-not-optional`, stating:

> "Read Layer 3 skills before calling tools. Before using any tool with an `agent_skills` field, read the referenced skill in `.agents/skills/`. These contain provider-specific prompting guidance, parameter optimization, and quality techniques that dramatically improve output."

This contract ensures that selectors surface `agent_skills` so the agent can read them before prompting, as documented in the repository's [`README.md`](https://github.com/calesthio/OpenMontage/blob/main/README.md).

## Practical Implementation: Reading Layer 3 Skills Before API Calls

The following patterns demonstrate how agents should load Layer 3 context before invoking generation tools.

### Video Generation with Kling

This example shows how to load skills for the Kling video generation tool:

```python
from tools.video.kling_video import KlingVideoTool
from lib.skill_loader import load_layer3_skill

# 1. Identify the tool and its Layer 3 dependencies

tool = KlingVideoTool()
layer3_names = tool.agent_skills  # ['ai-video-gen', 'kling-official']

# 2. Read each Layer 3 skill file from .agents/skills/

layer3_context = {}
for name in layer3_names:
    path = f".agents/skills/{name}/SKILL.md"
    layer3_context[name] = load_layer3_skill(path)

# 3. Build a prompt using provider-specific guidance

prompt = f"""
{layer3_context['ai-video-gen']['prompt_header']}
Generate a 30-second cinematic clip of a futuristic city at dusk.
{layer3_context['ai-video-gen']['quality_keywords']}
"""

# 4. Call the tool with the enriched prompt and optimized parameters

result = tool.run(
    prompt=prompt, 
    **layer3_context['ai-video-gen']['default_params']
)

```

The `load_layer3_skill` helper parses the markdown skill file and extracts sections such as `prompt_header`, `quality_keywords`, and `default_params`, ensuring the final request leverages every available quality optimization.

### Text-to-Speech with OpenAI TTS

A similar pattern applies to audio generation:

```python
from tools.audio.openai_tts import OpenAITTS

# Load the Layer 3 skill for OpenAI's TTS model

skill = load_layer3_skill(".agents/skills/openai-tts/SKILL.md")

# Construct prompt using vendor-specific voice guidance

prompt = f"{skill['voice_prompt']} Say: 'Welcome to OpenMontage.'"

# Execute with optimized parameters from the skill pack

audio = OpenAITTS().run(prompt=prompt, **skill['default_params'])

```

## Summary

- **Layer 3 skill reading** is a mandatory prerequisite for all generation tools in OpenMontage, enforced through the `agent_skills` field and [`AGENT_GUIDE.md`](https://github.com/calesthio/OpenMontage/blob/main/AGENT_GUIDE.md).
- The architecture separates generic tool implementations (Layer 1), project guides (Layer 2), and deep vendor expertise (Layer 3) to prevent quality decay.
- Reading `.agents/skills/` files provides **provider-specific prompt syntax**, **optimal parameter ranges**, and **hidden quality features** unavailable through standard API documentation.
- This requirement guarantees cinema-quality outputs, reproducible audits, and cost-effective generation compared to direct API calls with generic prompts.

## Frequently Asked Questions

### What is Layer 3 skill reading in OpenMontage?

Layer 3 skill reading is an architectural requirement that forces agents to load vendor-specific technical documentation from `.agents/skills/` before invoking any generation tool. These skill packs contain deep knowledge about API syntax, optimal parameters, and quality-boosting techniques specific to each provider, ensuring the agent constructs requests using validated best practices rather than generic templates.

### How does Layer 3 skill reading differ from direct API calls?

Direct API calls typically send standardized prompts with default parameters, missing provider-specific optimizations and hidden features. Layer 3 skill reading systematically enriches the prompt with vendor-validated grammar, optimal resolution and frame-rate settings, and undocumented quality tricks before the API request is constructed, resulting in significantly higher fidelity outputs without additional model training or cost.

### Where is the Layer 3 requirement enforced in the codebase?

The requirement is enforced in two critical locations: [`AGENT_GUIDE.md`](https://github.com/calesthio/OpenMontage/blob/main/AGENT_GUIDE.md) explicitly mandates reading Layer 3 skills before tool invocation at the `#layer-3-not-optional` anchor, and each tool implementation declares its dependencies in the `agent_skills` field. For example, [`tools/video/video_compose.py`](https://github.com/calesthio/OpenMontage/blob/main/tools/video/video_compose.py) at line 70 lists `["remotion-best-practices", "remotion", "ffmpeg"]` as mandatory prerequisites.

### Can I use OpenMontage tools without Layer 3 skills?

No. The architecture treats Layer 3 skills as non-optional dependencies. The agent guide states that before using any tool with an `agent_skills` field, the agent must read the referenced skill files. Bypassing this step would violate the quality-gate philosophy and result in unoptimized, potentially invalid API requests that fail to leverage provider-specific capabilities documented in files like [`.agents/skills/seedance-2-0/SKILL.md`](https://github.com/calesthio/OpenMontage/blob/main/.agents/skills/seedance-2-0/SKILL.md).
