Generating Agents

Agent Generation

Agent definition file generation with mandatory schema validation against schemas/agent.schema.json

Generates agent definition files that are schema-compliant by construction. Every generated agent MUST pass schemas/agent.schema.json validation before being written to disk.

Canonical Schema Reference (schemas/agent.schema.json)

CRITICAL: Every agent MUST comply with this schema. Memorize these constraints:

Required Frontmatter Fields

| Field | Type | Constraints | |-||-| | name | string | Pattern: ^[a-z0-9-]+$, min 3 chars, must match filename without .md | | description | string | Min 20 chars | | type | const | Must be "agent" | | version | string | Semantic version: ^\\d+\\.\\d+\\.\\d+$ (e.g. 1.0.0) | | domain | enum | ONLY: ai-ml, development, testing, review, documentation, debugging, deployment, analysis, orchestration, trading, sap, dotnet, java, web, devops, onboarding, factory | | skills | array | Min 2 items, each matching ^[a-z0-9-]+(/[a-z0-9-]+)*$ | | knowledge | array | Min 2 items, each matching ^[a-z0-9-]+\\.json$ (NO path prefixes like schemas/) | | tools | array | Min 1 item (use ["none"] if no tools) | | workflows | array | Min 1 item (use ["none"] if no workflows) | | blueprints | array | Min 1 item (use ["none"] if no blueprints) |

Optional Fields

| Field | Type | Description | |-||-| | mcp_servers | array of strings | MCP servers this agent uses | | agent_team | array of strings | Other agents this agent coordinates with |

Domain Mapping Guide

Use this mapping when the natural domain doesn't match an allowed value:

| Natural Domain | Use Instead | ||-| | data-science | analysis | | security | testing | | integration | orchestration | | general | development (for coders), documentation (for writers), deployment (for infra) | | meta | factory |

Process

1. Review the task requirements.
2. Apply the skill's methodology.
3. Validate the output against the defined criteria.

Step 1: Load Agent Pattern

For each requested agent:

1. Load pattern from {directories.patterns}/agents/{agent-id}.json
2. Parse metadata, frontmatter, and sections
3. Identify customization points

Step 2: Validate Against Schema BEFORE Writing

CRITICAL VALIDATION CHECKLIST - verify each constraint:

[ ] name: lowercase kebab-case, >= 3 chars, matches filename
[ ] description: >= 20 characters
[ ] type: exactly "agent"
[ ] version: semantic version format (e.g. "1.0.0")
[ ] domain: is in the allowed enum list above
[ ] skills: array with >= 2 items, each lowercase kebab-case
[ ] knowledge: array with >= 2 items, each "name.json" format (no paths)
[ ] tools: array with >= 1 item (use ["none"] for no tools)
[ ] workflows: array with >= 1 item (use ["none"] for no workflows)
[ ] blueprints: array with >= 1 item (use ["none"] for no blueprints)
[ ] **New Requirement**: Run `verify_structures.py` to ensure H1, Purpose, and Important Rules sections are present.

Step 3: Render Markdown

name: {name}
description: {description}
type: agent
version: 1.0.0
domain: {domain from allowed enum}
skills: [{skill-1}, {skill-2}, ...]
knowledge: [{file-1}.json, {file-2}.json, ...]
tools: [{tool-1}, ...]
workflows: [{workflow-1} or "none"]
blueprints: [{blueprint-1} or "none"]

### Step 4: Write File
Write to target location:
- Path: `{TARGET}/{directories.agents}/{name}.md`
- Encoding: UTF-8

### Step 5: Post-Creation Sync (Factory Only)

**CRITICAL:** After creating agents in the Antigravity Agent Factory, run the repo-sync:

```powershell
{PYTHON_PATH} {directories.scripts}/validation/schema_validator.py --summary
{PYTHON_PATH} {directories.scripts}/validation/validate_readme_structure.py --update
{PYTHON_PATH} {directories.scripts}/build_knowledge_crossref.py
{PYTHON_PATH} {directories.scripts}/validation/verify_structures.py

Common Schema Violations and Fixes

Important Rules

1. ALWAYS validate against schema BEFORE writing - Never create an agent without checking all required fields
2. Use {directories.XXX} path variables - NEVER hardcode directory paths
3. Lowercase kebab-case filenames - All files use my-agent.md format
4. Knowledge refs are basename only - Use file.json not schemas/file.json
5. Empty arrays forbidden - Use ["none"] instead of [] for tools/workflows/blueprints
6. Run schema_validator.py after creation - Catch any remaining issues
7. Update knowledge-cross-reference.json - Run build_knowledge_crossref.py after adding agents
8. Update README counts - Run validate_readme_structure.py after adding agents
