🧾 Agentspecs

YAML-based specifications for AI agents, MCP servers, skills and more...

Overview

This repository is the source of truth for declarative specs consumed by Agent Runtimes code generation.

The YAML files in agentspecs/agentspecs are compiled into Python and TypeScript catalogs used by runtime and UI layers.

Versioning

All specs are versioned.

Required Version Field

Each spec includes:

• id: logical identifier
• version: semantic version string (currently 0.0.1 for all shipped specs)

Example:

id: data-acquisition
version: 0.0.1
name: Data Acquisition Agent

Versioned References

Cross-spec references should use id:version format.

Examples:

mcp_servers:
  - tavily:0.0.1

skills:
  - github:0.0.1

envvars:
  - TAVILY_API_KEY:0.0.1

agent_spec_id: comprehensive-sales-analytics:0.0.1

Runtime Catalog Aliases

Generated catalogs are keyed by unversioned id only (e.g. data-acquisition).

The get_* / get*Spec accessor functions accept both bare ids and versioned refs (data-acquisition:0.0.1), stripping the version suffix automatically.

Iterating catalog values (.values() / Object.values()) returns each spec exactly once — no deduplication is needed.

Default Version During Codegen

Code generation enforces a default spec version of 0.0.1 if omitted (scripts/codegen/versioning.py).

In practice, specs in this repository should always declare version explicitly.

Spec Types

Agents (agentspecs/agents)

Defines agent behavior and runtime defaults.

Common fields:

• id, version, name, description, enabled
• model, sandbox_variant, memory
• mcp_servers, skills, tools
• environment_name
• icon, emoji, color
• suggestions, welcome_message, welcome_notebook, welcome_document
• system_prompt, system_prompt_codemode_addons
• Optional workflow fields such as goal, trigger, guardrails, evals, output, notifications, advanced

Teams (agentspecs/teams)

Defines multi-agent orchestration over an underlying agent spec.

Common fields:

• id, version, name, description, enabled
• agent_spec_id (versioned)
• orchestration_protocol, execution_mode, supervisor
• agents (team members), reaction_rules, health_monitoring
• notifications, output

MCP Servers (agentspecs/mcp-servers)

Defines MCP integrations and process startup configuration.

Common fields:

• id, version, name, description
• command, args, transport
• env, envvars (usually versioned)
• tags, icon, emoji

Skills (agentspecs/skills)

Defines reusable skill modules.

Common fields:

• id, version, name, description, module
• envvars, optional_env_vars, dependencies
• tags, icon, emoji

Tools (agentspecs/tools)

Defines runtime tool metadata and implementation binding.

Common fields:

• id, version, name, description, enabled
• approval
• runtime.language, runtime.package, runtime.method
• tags, icon, emoji

Env Vars (agentspecs/envvars)

Defines environment variable metadata.

Common fields:

• id, version, name, description
• registrationUrl, tags, icon, emoji

Models (agentspecs/models)

Defines model options available to specs.

Common fields:

• id, version, name, description, provider
• default
• required_env_vars

Other Catalogs

• memory: memory backend options
• guardrails: security and policy profiles
• evals: evaluator definitions
• benchmarks: benchmark suites (with evaluator dependencies)
• triggers: reusable trigger templates
• outputs: output format templates/capabilities
• notifications: notification channel templates

Adding or Updating Specs

1. Add or edit YAML in the relevant folder under agentspecs/agentspecs.
2. Always set id and version.
3. Use versioned cross-references (name:version) in fields that reference other specs.
4. Keep IDs stable; bump version when introducing breaking changes.
5. Regenerate catalogs in Agent Runtimes (make specs) and validate consumers.

Parameters (Launch-Time Inputs)

Agentspecs support a parameters field using JSON Schema. This lets one spec be reused across multiple launches while keeping runtime inputs validated and explicit.

What parameters provide

• Validation: enforce type, enum, required, and defaults.
• Templating: inject values into text fields using {{parameter_name}}.
• Reusability: same agent spec, different runtime contexts.

Typical template targets

• system_prompt
• welcome_message
• pre_hooks.sandbox
• other template-aware text fields

Example

id: demo-parameters
version: 0.0.1

parameters:
  type: object
  properties:
    project:
      type: string
      default: Orbit
    role:
      type: string
      enum:
        - product analyst
        - engineering lead
        - support specialist
      default: product analyst
  required:
    - project

welcome_message: >
  This runtime was launched for project {{project}}.

system_prompt: >
  You are an assistant dedicated to {{project}}.

pre_hooks:
  sandbox:
    - |
      project_name = """{{project}}"""

Validation notes

• Missing required parameters fail validation.
• Invalid enum values fail validation.
• Optional parameters use defaults when available.

Best Practices

• Use kebab-case IDs for most specs (analyze-support-tickets).
• Use UPPER_SNAKE_CASE for env var IDs (TAVILY_API_KEY).
• Keep descriptions concise and action-oriented.
• Prefer explicit versioned references, even when alias lookup works.
• Maintain backward compatibility by preserving old versions when possible.
