Imports currently only accept a string path or {path, inputs} object. This adds a uses/with form (mirroring GitHub Actions reusable workflow syntax), a top-level import-schema field for declaring and validating those inputs, and new expressions for accessing them.

New syntax

# Shared workflow (shared/worker.md)
---
import-schema:
  region:
    type: string
    required: true
  environment:
    type: choice
    options: [staging, production]
    required: true
  count:
    type: number
    default: 10
  languages:
    type: array
    items:
      type: string
    required: true
  config:
    type: object
    description: Configuration object
    properties:
      apiKey:
        type: string
        required: true
      timeout:
        type: number
        default: 30

Deploy ${{ github.aw.import-inputs.count }} items to ${{ github.aw.import-inputs.region }}.
API key: ${{ github.aw.import-inputs.config.apiKey }}.
Languages: ${{ github.aw.import-inputs.languages }}.
# Importing workflow
imports:
  - uses: shared/worker.md
    with:
      region: us-east-1
      environment: staging

      languages: ["go", "typescript"]
      config:

New: Parameterized Serena shared workflow

A new shared/mcp/serena.md workflow uses import-schema to accept a languages array and dynamically configure tools.serena:

# Any workflow
imports:
  - uses: shared/mcp/serena.md
    with:
      languages: ["go", "typescript"]

Changes

  • pkg/parser/import_bfs.goparseImportSpecsFromArray now accepts uses as alias for path and with as alias for inputs
  • pkg/parser/import_field_extractor.go — validates with values against the imported workflow's import-schema: required fields, unknown keys, type matching (string, number, boolean, choice, object, array), choice membership, object sub-property validation, and per-element array item type validation; adds substituteImportInputsInContent to apply expression substitution to raw imported file content (including YAML frontmatter) before parsing
  • pkg/parser/include_processor.go — adds import-schema to the allowed fields list for shared workflow frontmatter; suppresses schema validation warnings for shared files containing unsubstituted ${{ }} expressions (resolved at import time)
  • pkg/parser/schemas/main_workflow_schema.json — adds import-schema top-level property supporting scalar, object, and array types; extends import item oneOf with uses/with object form; allows object and array values in with
  • pkg/workflow/frontmatter_types.go — adds ImportSchema map[string]any field to FrontmatterConfig
  • pkg/workflow/expression_patterns.go — adds AWImportInputsPattern / AWImportInputsExpressionPattern for github.aw.import-inputs.* and dotted paths (github.aw.import-inputs.<key>.<subkey>)
  • pkg/workflow/expression_extraction.goSubstituteImportInputs handles github.aw.inputs.* (legacy), github.aw.import-inputs.<key> (scalar/array), and github.aw.import-inputs.<key>.<subkey> (object sub-field); adds resolveImportInputPath for dotted-path lookup; arrays and maps serialize as JSON (valid YAML inline syntax) via marshalImportInputValue
  • pkg/workflow/expression_safety_validation.go — permits github.aw.import-inputs.* and dotted forms through expression safety checks
  • .github/workflows/shared/mcp/serena.md — new parameterized shared workflow using import-schema with languages: {type: array} that dynamically sets tools.serena based on the provided language list

Backward compatibility is preserved: imports without import-schema accept any with/inputs values unchanged.

@copilot allow one level deep object definitions in import-schema

Done in 8714dad. import-schema now supports type: object with a one-level deep properties map:

import-schema:
  config:
    type: object
    properties:
      apiKey:
        type: string
        required: true
      timeout:
        type: number
        default: 30

Sub-fields are validated (unknown keys, required checks, scalar type matching) and accessible via ${{ github.aw.import-inputs.config.apiKey }} expressions in the shared workflow prompt.

@copilot create a shared agentic workflow that uses import-schema and inputs to reimplement the "serena" tool support.

  • add support for array of string as import input simple type
  • takes the list of languages to add
  • configures the MCP and the runtimes based on the languages selected

…-schema

- Add `type: array` with optional `items` validation to import-schema
- Apply expression substitution to imported workflow frontmatter before processing,
  enabling `tools.serena: ${{ github.aw.import-inputs.languages }}` patterns
- Serialize arrays as JSON when substituting into raw content (valid YAML inline)
- Add `import-schema` to allowed fields list for shared workflow frontmatter
- Suppress schema validation warnings for shared files with unsubstituted expressions
- Create `.github/workflows/shared/mcp/serena.md` using import-schema with languages array
- Add TestImportSchemaArrayType with 4 sub-tests covering valid/invalid array inputs

@copilot create a shared agentic workflow that uses import-schema and inputs to reimplement the "serena" tool support.

  • add support for array of string as import input simple type...

Done in 242029a. Here's what was added:

type: array support in import-schema:

import-schema:
  languages:
    type: array
    items:
      type: string
    required: true

Array items are validated element-by-element. Arrays serialize as JSON (["go","typescript"]) when substituted into raw YAML frontmatter, producing valid inline YAML.

Frontmatter expression substitution:
${{ github.aw.import-inputs.* }} expressions are now applied to the imported workflow's raw content (including YAML frontmatter) before parsing. This allows fields like tools.serena and runtimes to be driven by import inputs.

New shared/mcp/serena.md:

# Importing workflow
imports:
  - uses: shared/mcp/serena.md
    with:
      languages: ["go", "typescript"]

The shared workflow declares languages via import-schema, sets tools: serena: ${{ github.aw.import-inputs.languages }}, and provides the standard Serena instructions in its markdown body. Adding runtimes to the shared workflow for node/python can be done the same way once you decide on the desired runtime mapping.
