Envelope Team

Design and generate .envelope.json AI agent team definition files — the open standard for building and deploying multi-agent teams on Envelope.

When to Use This Skill

• User asks to build, design, or generate an Envelope team
• User describes a workflow that could be automated by a team of AI agents
• User wants to create a .envelope.json file for deployment
• User needs help with agent hierarchy, access policies, or gates

What This Skill Does

1. Takes a natural-language description of the team's purpose
2. Designs the agent hierarchy (supervisor → managers → workers)
3. Generates a schema-valid .envelope.json file
4. Includes access policies, variables, secrets, and gates as appropriate
5. Explains any schema concepts the user asks about

How to Use

Basic Usage

Build me an Envelope team for customer support triage — one supervisor,
two agents that read Zendesk tickets, and a Slack notifier for escalations.

Create an Envelope team definition for outbound sales — an SDR manager
overseeing two SDRs who work HubSpot leads and a RevOps analyst.

With human-in-the-loop gates

Build an Envelope team that drafts marketing emails and pauses for
human approval before sending.

Example

User: "Build me an Envelope team for content moderation — a supervisor and two reviewer agents that check posts against community guidelines."

Schema Reference

Top-level fields

Field	Required	Description
$schema	yes	Always https://schema.openenvelope.org/team/v1.json
name	yes	Human-readable team name
slug	yes	URL-safe, lowercase, hyphens only
version	yes	Semver e.g. "1.0.0"
description	yes	What this team does
visibility	yes	"public" · "team" · "private"
requiredVariables	no	Non-sensitive config, interpolated via {{varName}}
requiredSecrets	no	API keys, stored encrypted, injected as ${SECRET_NAME}
schedule	no	Cron schedule { cron, timezone, task }
agents	yes	Agent definitions
gates	no	Human-in-the-loop checkpoints

Agent fields

Field	Required	Description
key	yes	Unique identifier within this file
name	yes	Display name
role	yes	Free-form e.g. "supervisor", "analyst", "sdr"
capabilities	yes	What this agent can do — used for delegation routing
model	yes	e.g. anthropic:claude-sonnet-4-5, anthropic:claude-haiku-3-5
systemPrompt	yes	Agent instructions. Use {{varName}} and ${SECRET_NAME}
reportsToKey	no	key of manager agent. Omit for the top-level supervisor
accessPolicy	no	Outbound HTTP allowlist

Hierarchy rule

Exactly one agent should have no reportsToKey — this is the supervisor that receives the initial task. All others reference their manager's key.

Access policy

"accessPolicy": {
  "accessPolicyVersion": "1",
  "rules": [
    { "host": "api.example.com", "action": "allow" },
    { "host": "*", "action": "deny" }
  ]
}

Human-in-the-loop gates

"gates": [
  {
    "name": "approval-check",
    "type": "approval",
    "trigger": { "afterAgent": "drafter" },
    "onApprove": "continue",
    "onReject": "halt"
  }
]

Tips

• Use anthropic:claude-sonnet-4-5 for supervisors and managers; anthropic:claude-haiku-3-5 for leaf agents doing repetitive work
• Put anything org-specific (company name, support email, Slack channel) in requiredVariables
• End access policy rules with { "host": "*", "action": "deny" } for a strict allowlist
• Add gates before any agent that sends emails, posts publicly, or makes purchases
• Validate before deploying: npx @openenvelope/schema validate ./team.envelope.json
