Victor SDK - Protocol definitions for vertical development

Victor SDK

Protocol and type definitions for building Victor verticals without pulling in the Victor runtime.

Overview

Use victor-sdk when you want to author or publish a vertical package. Use victor-ai when you want to run a vertical inside the Victor host runtime.

The supported external authoring model is contract-first:

• vertical packages depend on victor-sdk only
• verticals declare tools, capabilities, prompts, teams, and workflow metadata through the SDK contract
• victor-ai remains responsible for runtime concerns such as agent creation, capability injection, and tool execution

Installation

SDK-only authoring

pip install victor-sdk

Runtime usage

pip install victor-ai

Stable SDK Surface

The core authoring surface is available from the top-level package:

from victor_sdk import (
    CURRENT_DEFINITION_VERSION,
    CapabilityIds,
    CapabilityRequirement,
    ToolNames,
    ToolRequirement,
    VerticalBase,
    VerticalDefinition,
)

Key pieces:

• VerticalBase: SDK base class for external verticals
• ToolNames: canonical SDK-owned tool identifiers
• CapabilityIds: canonical SDK-owned runtime capability identifiers
• ToolRequirement / CapabilityRequirement: typed requirement declarations
• VerticalDefinition: validated serializable manifest returned by get_definition()

Quick Start

from victor_sdk import (
    CapabilityIds,
    CapabilityRequirement,
    ToolNames,
    ToolRequirement,
    VerticalBase,
)


class SecurityVertical(VerticalBase):
    name = "security"
    description = "Security analysis and audit workflows"
    version = "1.0.0"

    @classmethod
    def get_name(cls) -> str:
        return cls.name

    @classmethod
    def get_description(cls) -> str:
        return cls.description

    @classmethod
    def get_tool_requirements(cls) -> list[ToolRequirement]:
        return [
            ToolRequirement(ToolNames.READ, purpose="inspect code and configs"),
            ToolRequirement(ToolNames.GREP, purpose="search for vulnerable patterns"),
            ToolRequirement(ToolNames.SHELL, required=False, purpose="run scanners"),
            ToolRequirement(ToolNames.WEB_SEARCH, required=False, purpose="look up CVEs"),
        ]

    @classmethod
    def get_capability_requirements(cls) -> list[CapabilityRequirement]:
        return [
            CapabilityRequirement(
                capability_id=CapabilityIds.FILE_OPS,
                purpose="read repository contents",
            ),
            CapabilityRequirement(
                capability_id=CapabilityIds.WEB_ACCESS,
                optional=True,
                purpose="fetch external security references",
            ),
        ]

    @classmethod
    def get_system_prompt(cls) -> str:
        return "You are a security-focused assistant."

    @classmethod
    def get_prompt_templates(cls) -> dict[str, str]:
        return {
            "audit": "Audit the target for security issues and explain severity."
        }

    @classmethod
    def get_task_type_hints(cls) -> dict[str, dict[str, object]]:
        return {
            "audit": {
                "hint": "Start with read-first reconnaissance, then validate findings.",
                "tool_budget": 12,
                "priority_tools": [ToolNames.READ, ToolNames.GREP, ToolNames.SHELL],
            }
        }

    @classmethod
    def get_team_declarations(cls) -> dict[str, dict[str, object]]:
        return {
            "security_review_team": {
                "name": "Security Review Team",
                "formation": "pipeline",
                "members": [
                    {
                        "role": "researcher",
                        "goal": "Inspect the target and identify likely risks.",
                    },
                    {
                        "role": "reviewer",
                        "goal": "Validate findings before escalation.",
                    },
                ],
            }
        }


definition = SecurityVertical.get_definition()
assert definition.definition_version == "1.0"
assert definition.tools == [ToolNames.READ, ToolNames.GREP, ToolNames.SHELL, ToolNames.WEB_SEARCH]
assert definition.team_metadata.teams[0].team_id == "security_review_team"

Definition Contract

VerticalBase.get_definition() is the preferred SDK contract. It returns a validated VerticalDefinition manifest that contains:

• definition_version
• canonical tool identifiers
• typed tool and capability requirements
• system prompt text
• prompt metadata and task-type hints
• team metadata such as declarative team layouts and the default team identifier
• declarative stage definitions
• workflow metadata such as initial stage, provider hints, and evaluation criteria

Compatibility note:

• get_config() still exists as a bridge for current victor-ai integrations
• VerticalDefinition.to_config() / from_config() bridge the legacy config shape
• VerticalDefinition.from_dict() supports serialized manifest round-tripping

Packaging

Register the vertical via the standard Victor entry point:

[project]
name = "victor-security"
version = "1.0.0"
dependencies = ["victor-sdk>=1.0.0"]

[project.entry-points."victor.verticals"]
security = "victor_security:SecurityVertical"

Discovery

Victor discovers external verticals through Python entry points:

from victor_sdk.discovery import get_global_registry

registry = get_global_registry()
verticals = registry.get_verticals()

Guides And Examples

• Vertical Development Guide
• Migration Guide
• Minimal SDK-only example
• Repository external package example

Testing

pip install -e ".[dev]"
pytest victor-sdk/tests -q

To verify compatibility with the runtime as well:

pip install -e ".[dev]" victor-ai
pytest victor-sdk/tests/unit tests/integration/test_sdk_integration.py -q

Versioning

The package follows semantic versioning, and the manifest contract is versioned separately via VerticalDefinition.definition_version. External verticals should treat the SDK contract as the source of truth for supported identifiers and manifest fields.
