[Schema Consistency] Schema Consistency Analysis Report

[github-actions[bot]]

Executive Summary

Comprehensive schema consistency analysis of the gh-aw repository reveals 7 major schema inconsistencies between the JSON schema definition and Go implementation:

---

Part 1: Schema Fields vs Go Structs

COMPLETE: All properties keys match between schema and Go implementation.

Schema contains 41 root-level properties:

bots, cache, check-for-updates, checkout, command, concurrency, container, dependencies, disable-model-invocation, engine, env, environment, features, github-app, if, import-schema, imports, infer, inlined-imports, jobs, labels, mcp-scripts, mcp-servers, metadata, name, network, observability, on, permissions, post-steps, private, rate-limit, resources, run-name, runs-on, runs-on-slim, runtimes, safe-outputs, sandbox, secret-masking, secrets, services, source, steps, strict, timeout-minutes, tools, tracker-id

Status: ✅ All documented in schema and Go implementation.

---

Part 2: Services Field & Allow-Host-Service-Ports

DOCUMENTED: The services: field is properly defined in schema at /pkg/parser/schemas/main_workflow_schema.json line 2780.

Schema Structure (line 2780):

• Type: object
• Properties: image, credentials, env, ports, volumes, options
• Service containers for the job

Implementation Details:

• File: pkg/workflow/compiler_types.go line 374
  • Go field: Services string (stores YAML)
• File: pkg/workflow/compiler_types.go line 439
  • Go field: ServicePortExpressions string (comma-separated expressions)

Feature Enabled by Commit 74416d9:

• Title: "feat: auto-generate --allow-host-service-ports from services: port mappings (feat: auto-generate --allow-host-service-ports from services: port mappings #23760)"
• Date: Tue Mar 31 21:33:59 2026 -0700
• Function: Auto-detects service ports and generates $\{\{ job.services['<id>'].ports['<port>'] }} expressions

Implementation Files:

• pkg/workflow/service_ports.go - Parses services YAML and extracts port expressions
• pkg/workflow/awf_helpers.go lines 100-107 - Injects --allow-host-service-ports flag to AWF
• pkg/workflow/compiler_orchestrator_workflow.go lines 535-545 - Calls extraction logic

Real-World Usage:

• .github/workflows/smoke-service-ports.md - Smoke test validating Redis service connectivity
• Documentation notes at .github/workflows/smoke-service-ports.md line 48: Must connect via host.docker.internal (not localhost)

Status: ✅ Fully documented in schema and properly implemented.

---

Part 3: Firewall/Engine Schema vs Implementation

Schema Definition: pkg/parser/schemas/main_workflow_schema.json lines 446-649

The engine: property references #/$defs/engine_config and supports:

1. String shorthand (e.g., engine: copilot)
2. Object with extended configuration (id, version, model, max-turns, concurrency, etc.)
3. Inline engine definition (runtime + provider configuration)
4. Full engine definition (id, display-name, description, provider, models)

Implementation: pkg/workflow/compiler_types.go

• Line 380: EngineConfig *EngineConfig - Extended engine configuration struct

Status: ✅ Schema matches implementation.

---

Part 4: Safe-Outputs Schema vs Implementation

Schema Structure: pkg/parser/schemas/main_workflow_schema.json - safe-outputs: property

Safe-Outputs Properties Include:

• jobs - Custom safe-output jobs (line 38 in schema: "jobs" field)
• env - Environment variables
• environment - GitHub deployment environment
• steps - User-provided steps
• scripts - Custom MCP scripts
• actions - Custom GitHub Actions
• runs-on - Runner configuration
• And 55+ additional properties including all safe output types (create-issue, add-comment, etc.)

Implementation:

• File: pkg/workflow/compiler_types.go lines 449-515
• Struct: SafeOutputsConfig with field Jobs map[string]*SafeJobConfig
• Safe job parsing: pkg/workflow/safe_jobs.go lines 33-149
• Job extraction: Only from safe-outputs.jobs location (line 330-334)

SafeJobConfig Structure (pkg/workflow/safe_jobs.go lines 18-29):

type SafeJobConfig struct {
    Name        string
    Description string
    RunsOn      any
    If          string
    Needs       []string
    Steps       []any
    Env         map[string]string
    Permissions map[string]string
    Inputs      map[string]*InputDefinition
    GitHubToken string
    Output      string
}
```

**Status:** ✅ Schema and implementation aligned.

---

## Part 5: Permissions Schema vs Code Constants - INCONSISTENCY FOUND

**⚠️ CRITICAL MISMATCH DETECTED**

**Schema Definition:** `pkg/parser/schemas/main_workflow_schema.json` - `$defs.github_actions_permissions.properties`

**Schema Contains (18 scopes):**
```
actions, all, attestations, checks, contents, deployments, discussions, id-token, issues, metadata, models, organization-projects, packages, pages, pull-requests, repository-projects, security-events, statuses, vulnerability-alerts

Go Code Defines (47 total scopes) - pkg/workflow/permissions.go lines 137-189:

Repository-level (19 in Go, 18 in schema):

• ✅ actions, attestations, checks, contents, deployments, discussions, id-token, issues, metadata, models, packages, pages, pull-requests, security-events, statuses, vulnerability-alerts
• ❌ MISSING FROM SCHEMA: administration, codespaces, environments, git-signing, repository-custom-properties, repository-hooks, single-file, workflows

Organization-level (15 in Go, 1 in schema):

• ✅ organization-projects (schema only lists this)
• ❌ MISSING FROM SCHEMA: members, organization-administration, team-discussions, organization-hooks, organization-members, organization-packages, organization-self-hosted-runners, organization-custom-org-roles, organization-custom-properties, organization-custom-repository-roles, organization-announcement-banners, organization-events, organization-plan, organization-user-blocking, organization-personal-access-token-requests

Non-standard (1 in Go):

• ❌ NOT IN SCHEMA: copilot-requests (marked as DRAFT/NON-STANDARD in code at line 155)

File References:

• Schema: pkg/parser/schemas/main_workflow_schema.json (lines 2-3 show total of 19 properties in github_actions_permissions)
• Go Constants: pkg/workflow/permissions.go lines 137-189
• Go Helper: pkg/workflow/permissions.go lines 225-244 (GetAllPermissionScopes returns all 47 permissions)

Status: ❌ SCHEMA SIGNIFICANTLY OUTDATED - Missing 28 permission scopes defined in Go code

---

Part 6: Documentation vs Schema Field List

Frontmatter Reference: docs/src/content/docs/reference/frontmatter.md

Services Documentation Location: Lines 564-581

## Service Containers (`services:`)

Defines service containers that run alongside your job (databases, caches, etc.).

services:
  postgres:
    image: postgres:13
    env:
      POSTGRES_PASSWORD: postgres
    ports:
      - 5432:5432

Note: The AWF agent runs inside an isolated Docker container. Service containers
expose ports on the runner host, not within the agent's network namespace. To
connect to a service from the agent, use `host.docker.internal` as the hostname
instead of `localhost`.

Allow-Host-Service-Ports Documentation:

• ❌ NOT DOCUMENTED in frontmatter.md
• Referenced only in: .github/workflows/smoke-service-ports.md (test workflow)

Imports Documentation: docs/src/content/docs/reference/imports.md line 234

• ✅ Services field documented as mergeable in imports

Status: ⚠️ PARTIAL - Services documented in frontmatter but --allow-host-service-ports feature is undocumented

---

Part 7: Workflow Files Using Services Field

Documented Usage (3 files):

1. .github/workflows/smoke-service-ports.md - Lines 14-23

   services:
     redis:
       image: redis:7
       ports:
         - 6379:6379

2. .github/workflows/smoke-service-ports.lock.yml - Generated lock file

3. .github/workflows/shared/mcp/jupyter.md - References services (mentioned in blog)

Status: ✅ Service containers documented and tested.

---

Part 8: Environment Variables Field Type

Schema Definition: pkg/parser/schemas/main_workflow_schema.json - properties.env

Schema Type (oneOf):

{
  "type": "object",
  "additionalProperties": { "type": "string" },
  "examples": { "NODE_ENV": "production" }
}
OR
{
  "type": "string"
}

Implementation: No specific Go struct field found (env is typically embedded in WorkflowData or handled as map[string]string)

Status: ✅ Schema supports both object and string formats correctly.

---

Actionable Findings

HIGH PRIORITY

1. Permissions Schema Update: Add 28 missing permission scopes to $defs.github_actions_permissions in schema
   • 8 repository-level: administration, codespaces, environments, git-signing, repository-custom-properties, repository-hooks, single-file, workflows
   • 15 organization-level: members, organization-administration, team-discussions, organization-hooks, organization-members, organization-packages, organization-self-hosted-runners, organization-custom-org-roles, organization-custom-properties, organization-custom-repository-roles, organization-announcement-banners, organization-events, organization-plan, organization-user-blocking, organization-personal-access-token-requests
   • 1 draft: copilot-requests

MEDIUM PRIORITY

2. Documentation Update: Add --allow-host-service-ports feature documentation to docs/src/content/docs/reference/frontmatter.md
   • Explain automatic detection from services field
   • Document the ${{ job.services['(id)'].ports['(port)'] }} expression generation
   • Include host.docker.internal connection requirement note

LOW PRIORITY

3. Schema Consistency: Consider documenting organization-level permission usage patterns in schema comments
