* Add missing validation for action.yml (parity with workflow files)
- Add uses format validation for composite action steps
- Validates owner/repo@ref format
- Supports docker:// and ./ local references
- Warns about shortened SHA refs (security concern)
- Detects reusable workflow references in wrong context
- Add if literal text detection for composite action steps
- Detects literal text outside ${{ }} that makes conditions always truthy
- Works for both plain string and mixed expression formats
- Uses shared hasFormatWithLiteralText() utility
- Add pre-if/post-if validation for node and docker actions
- Errors on explicit ${{ }} syntax (runner only supports implicit expressions)
- Literal text detection for implicit expressions
- New runs-if schema type with proper context (runner, github, job, env, inputs, status functions)
- Validates only in strict schema used by language services
- Add format() function validation for all expressions
- Validates format string syntax in all expression contexts
- Checks argument count matches placeholders
- Fix env and matrix context providers to return complete=false
- Prevents false positive 'unknown context' errors
- Matches behavior of other dynamic contexts (secrets, vars, etc.)
- Refactor validation utilities into utils/validate-uses.ts and utils/validate-if.ts
- Shared between workflow and action validation
- Consistent error messages and codes
* Add strategy and matrix contexts to runs-if definition
Based on runner source code analysis (actions/runner):
- ExecutionContext.InitializeJob() populates ExpressionValues from message.ContextData
- strategy and matrix are part of message.ContextData, available before any steps run
- StepsRunner evaluates all steps (pre, main, post) using the same code path
Did NOT add:
- steps: empty at pre-if time (no steps completed yet)
- hashFiles: workspace files don't exist at pre-step time
- Set main as required in node-runs-strict schema definition
- Add validation for invalid key combinations based on using value
- Add validation for missing required keys (main for node, steps for composite, image for docker)
- Filter autocomplete suggestions based on using value
- Prioritize 'using' in completions when not set yet
Fixes context-aware autocomplete for action.yml files where different
action types (node, composite, docker) have different valid keys under runs:
