    • Support for all ADM types: STRING, NUMBER, INTEGER, BOOLEAN, OBJECT, ARRAY
    • Comprehensive validation: length, range, pattern, enum constraints
    • Nested object and array schemas
    • JSON serialization/deserialization via to_map/1 and from_map/1

  • Altar.ADM.Tool - Top-level container for function declarations

    • Organizes related functions into cohesive tools
    • Validates unique function names within tool
    • Helper functions: function_names/1, find_function/2
    • JSON serialization support

  • Altar.ADM.ToolManifest - Deployable tool collection for GRID

    • Semantic version tracking
    • Metadata support for deployment information
    • Global function name uniqueness validation across all tools
    • JSON manifest file I/O for GRID Host startup
    • Helper functions: all_function_names/1, find_function/2, has_function?/2, tool_count/1, function_count/1

  • Comprehensive Test Suite - 145 new tests

    • test/altar/adm/schema_test.exs - 70 tests for Schema validation
    • test/altar/adm/tool_test.exs - 40 tests for Tool structure
    • test/altar/adm/tool_manifest_test.exs - 75 tests for ToolManifest
    • All tests passing (187 total, 100% pass rate)

  • Architecture Documentation

    • IMPLEMENTATION_SUMMARY.md - Quick reference for v0.2.0 features
    • REVIEW_INDEX.md - Navigation guide
    • TEST_COMPLETION_SUMMARY.md - Test implementation details

Changed

  • Altar.ADM module - Updated with new constructors

    • Added new_schema/1 for Schema creation
    • Added new_tool/1 for Tool creation
    • Added new_tool_manifest/1 for ToolManifest creation
    • Enhanced module documentation with examples

  • Documentation - Updated mix.exs docs configuration

    • Added new modules to "ADM (Data Model)" group
    • Proper ordering and organization

Technical Details

  • ADM Implementation: 40% → 90% complete
  • New Code: ~1,200 lines of implementation + ~1,200 lines of tests
  • Test Execution: 0.2s for 187 tests
  • Specification Alignment: Full alignment with ADM v1.0 spec for implemented features

Migration Notes

This release is fully backward compatible. All existing code continues to work. New features (Schema, Tool, ToolManifest) are additive and optional.

[0.1.0] - 2025-08-07

🎉 Added - First Implementation Release

This is the first official implementation release of the ALTAR protocol, providing a robust, production-ready foundation for local AI tool execution in Elixir.

🏛️ Architectural Foundation (Altar.ADM)

  • Validated Data Model: Implemented the complete Altar.ADM (ALTAR Data Model) layer with type-safe structs (FunctionDeclaration, FunctionCall, ToolResult, ToolConfig).
  • Smart Constructors: All data model structs are created via new/1 constructors that perform comprehensive validation, ensuring no malformed data can exist at runtime.

🚀 Local Execution Runtime (Altar.LATER)

  • Stateful Tool Registry: Implemented Altar.LATER.Registry as a robust GenServer to manage the state of registered tool functions safely. It prevents duplicate registrations and validates function arity.
  • Stateless Tool Executor: Implemented the Altar.LATER.Executor, a pure and stateless module that safely executes tool calls. It includes try/rescue blocks to gracefully handle exceptions within tool code, always returning a valid ToolResult.

🧬 OTP Compliance

🧪 Testing

  • Comprehensive Test Suite: Added a full suite of ExUnit tests, achieving 100% coverage for all modules in the ADM and LATER layers. Tests validate all success paths, failure paths, and edge cases.

[0.0.1] - 2025-08-03

Added

  • Initial Project Setup: Created the mix.exs file for the altar hex package.
  • Protocol Specification: Finalized the v1.0 Altar Protocol specification, including the design, requirements, and implementation plan.
  • Documentation: Created the initial README.md with project overview, vision, and documentation links.
  • Styling: Applied a professional color scheme to all Mermaid diagrams based on the project logo.
  • Configuration: Created a comprehensive .gitignore file for a standard Elixir project.
  • License: Added the MIT License.

Changed

  • Project Status: The project is now considered v1.0 complete and is ready for implementation.

  • N/A (Initial Release)
