Agent-Native Architecture

Architecting the
Agent-Native Future

We are a collective of AI engineers building applications where agents are first-class citizens. We don't just consult; we co-build agent-native architectures ensuring parity, granularity, and composability.

Parity

Whatever the user can do through the UI, the agent must be able to achieve through tools. We build capability maps to ensure 1:1 coverage.

Granularity

We prefer atomic primitives over monolithic logic. Features become outcomes achieved by an agent in a loop using granular tools.

Composability

New features = new prompts. By building atomic tools, we enable agents to compose complex workflows without writing new code.

Emergent Capability

Build atomic tools and let agents solve problems you didn't explicitly design for. We optimize for the unexpected.

CRUD Completeness

For every entity, we verify the agent has full Create, Read, Update, and Delete capabilities.

Files as Universal Interface

Agents know how to manipulate files. We use file systems as the primary interface for agent-user collaboration.

Core Principles

A practical reference for building applications where agents are first-class citizens.

Input

Action

Result

1. Parity

Whatever the user can do through the UI, the agent must be able to achieve through tools. We build specific capability maps to ensure 1:1 coverage between user actions and agent methods.

2. Granularity

We prefer atomic primitives. Features are outcomes achieved by an agent in a loop. Instead of 'classify_and_organize_files', we give the agent 'read_file', 'move_file', and 'bash'.

tools/
read_filefn()
write_filefn()
list_dirfn()

3. Composability

New features = new prompts. When tools are atomic and parity exists, we can create complex workflows just by instructing the agent, without writing new code.

4. Emergent Capability

Agents can accomplish things you didn't explicitly design for. By building atomic tools, we empower agents to compose solutions for unexpected user requests.

Files as Universal Interface

Agents already know how to manipulate files using tools like grep, mv, and mkdir. We leverage the file system as the primary interface for agent-user collaboration, ensuring portability, inspectability, and a clear information architecture.

Structure

  • {entity}.jsonEntity Data
  • {type}.mdContent
  • agent_log.mdAgent Logs
  • {id}.checkpointCheckpoints

Context Pattern

Agents read a context.md at session start to understand who they are, what they know about the user, and what exists in the environment.

~/project-root
Documents/
├── AgentCheckpoints/     # Ephemeral state
│   ├── session_123.ckpt
│   └── session_124.ckpt
├── AgentLogs/            # Execution history
│   └── 2024-01-15.log
└── Research/             # Durable user work
    ├── project_alpha/
    │   ├── context.md        # Injection source
    │   └── data.json
    └── notes/
        └── ideas.md

Methodology

We don't just write prompts. We build systems. Our methodology ensures robustness, scalability, and transparency.

Tool Design

Tools are the hands of the agent. We design them for parity and composability.

Vocabulary AnchoringUsing specific tool names like 'create_note' to teach concepts better than generic file operations.
GuardrailsValidation logic embedded in tools, not left to agent judgment.
EfficiencyCommon multi-step operations bundled into single tools for performance.

Context Injection

The prompt is the operating system. We structure context to prevent starvation.

Available ResourcesDynamic listing of files, projects, and data available to the agent.
CapabilitiesExplicit instructions on what the agent can and cannot do.
Recent ActivityA memory stream of recent user and agent actions to maintain continuity.

Communication

Agents must be transparent. We implement strict event-driven communication protocols.

No Silent ActionsEvery state change is visible immediately in the UI.
Progress IndicatorsShow 'Thinking', 'Tool Call', and 'Result' states explicitly.
Ephemeral LogsDetailed internal logs for debugging, clean summaries for users.

Completion Signals

We don't guess when the agent is done. We require explicit signals.

Explicit ToolAgents use a specific 'complete_task' tool to finish a workflow.
Structured ResultsReturns success status, output summary, and continuation flags.
CheckpointsState is saved at every completion step to allow resuming.

Common Anti-Patterns

Avoid these common pitfalls when building agentic systems.

Agent as router only
Let agent act, not just route
Workflow-shaped tools (analyze_and_organize)
Break into atomic primitives (read, move)
Orphan UI actions
Maintain 1:1 parity with tools
Context starvation
Inject resources into system prompt
Gates without reason
Default to open, keep primitives available
Heuristic completion detection
Explicit completion tool signal
Static API mapping
Dynamic capability discovery

Services

From architecture to production, we help you build applications where agents are first-class citizens.

Strategic Architecture

We design the agent loop, capability maps, and data strategy to ensure your system is ready for agentic interaction.

Tool Implementation

We build robust, atomic tools in TypeScript or Python that connect your business logic to agent reasoning.

Legacy Transformation

We refactor monolithic features into granular primitives, making your existing platform agent-ready.

Production Delivery

We handle the critical infrastructure: state management, checkpoints, eval pipelines, and observability.
