Release Notes: v0.5.0¶

Release Date: 2026-04-19

Overview¶

OmniAgent v0.5.0 introduces a compiled skills system, storage abstraction layer, and functional options pattern for more flexible agent configuration.

Highlights¶

Compiled Skills - Register Go functions directly as tools without YAML/SKILL.md parsing
Storage Abstraction - Pluggable storage backends (SQLite, in-memory) for agent state
Functional Options - Clean configuration API with WithCompiledSkills, WithStorage, etc.

New Features¶

Compiled Skills System¶

Register Go functions as tools that the agent can invoke:

import "github.com/plexusone/omniagent/skills"

// Define a compiled skill
weatherSkill := skills.CompiledSkill{
    Name:        "get_weather",
    Description: "Get current weather for a location",
    Parameters: map[string]any{
        "type": "object",
        "properties": map[string]any{
            "location": map[string]any{"type": "string"},
        },
        "required": []string{"location"},
    },
    Handler: func(ctx context.Context, args map[string]any) (string, error) {
        location := args["location"].(string)
        return fetchWeather(location)
    },
}

// Register with the skills registry
skills.RegisterCompiled(weatherSkill)

Storage Interface¶

Pluggable storage backends for agent state persistence:

import "github.com/plexusone/omniagent/storage"

// SQLite backend (default)
sqliteStore, _ := storage.NewSQLiteBackend("./omniagent.db")

// In-memory backend (for testing)
memStore := storage.NewMemoryBackend()

// Use with agent
agent, _ := omniagent.NewAgent(
    omniagent.WithStorage(sqliteStore),
)

Functional Options¶

Clean API for agent configuration:

agent, err := omniagent.NewAgent(
    omniagent.WithModel("gpt-4o"),
    omniagent.WithCompiledSkills(weatherSkill, searchSkill),
    omniagent.WithStorage(sqliteStore),
    omniagent.WithObservability(observeHook),
)

Bug Fixes¶

Fixed Docker container timeout handling in sandbox executor
Fixed linting errors for errcheck and gofmt compliance

Build Changes¶

Switched to pure-Go SQLite driver (modernc.org/sqlite) for better cross-platform support
No CGO required for SQLite functionality

Dependency Upgrades¶

Package	From	To
`omnillm`	v0.13.0	v0.15.2
`omnivoice`	v0.5.1	v0.7.2
`omnichat`	v0.3.0	v0.6.0
`omniobserve`	v0.7.0	v0.8.0

Provider Consolidation¶

The OpenAI and Twilio providers have been consolidated:

omnillm-openai → omni-openai/omnillm
omnivoice-openai → omni-openai/omnivoice
omnivoice-twilio → twilio-go/omnivoice

This is an internal change with no impact on the OmniAgent API.

Upgrade Guide¶

From v0.4.0¶

Update your dependency:

go get github.com/plexusone/omniagent@v0.5.0
go mod tidy

(Optional) Migrate to functional options:

// Old style
agent := &omniagent.Agent{
    Model: "gpt-4o",
}

// New style (recommended)
agent, _ := omniagent.NewAgent(
    omniagent.WithModel("gpt-4o"),
)

(Optional) Add compiled skills for better performance:

// Instead of parsing SKILL.md files at runtime
skills.RegisterCompiled(myGoSkill)
