📝 Walkthrough

Walkthrough

This pull request introduces a new Trae command adapter for the command generation system. The adapter handles command storage at .trae/commands/opsx/<commandId>.md with YAML frontmatter formatting. Changes include adapter implementation, registry integration, gitignore entry, documentation updates, and comprehensive test coverage.

Changes

Cohort / File(s)	Summary
Configuration & Documentation .gitignore, docs/supported-tools.md	Added .trae/ directory to gitignore and updated supported tools documentation to reflect new OPSX workflow path (.trae/commands/opsx/ with /opsx:* invocation).
Adapter Implementation src/core/command-generation/adapters/trae.ts, src/core/command-generation/adapters/index.ts	Introduced new traeAdapter with toolId 'trae' that generates paths as .trae/commands/opsx/<commandId>.md and formats files with YAML frontmatter (name, description, category, escaped tags) followed by content body. Added public export in adapter index.
Integration src/core/command-generation/registry.ts	Registered traeAdapter in CommandAdapterRegistry static initializer to include it in available adapters at startup.
Test Coverage test/core/command-generation/adapters.test.ts	Added comprehensive test suite for traeAdapter covering toolId validation, path generation, YAML frontmatter formatting with escaped values, empty tags handling, and cross-platform path semantics consistency.

Poem

🐰 A Trae adapter springs to life, so spry,
With YAML frontmatter reaching for the sky,
Through .trae/commands/opsx/ it hops with glee,
Tags formatted, paths precise—a joy to see! 🌿✨

Greptile Overview

Greptile Summary

• Adds a new trae tool adapter implementation and wires it into the command-generation adapter registry.
• Updates adapter exports/registration so trae can be selected/auto-detected like other supported tools.
• Extends adapter tests to validate Trae adapter behavior and registration.
• Updates supported-tools documentation (and gitignore) to reflect the new adapter support.

Confidence Score: 2/5

• Unable to verify PR correctness due to missing code/diff inspection in this review run.
• The required review artifacts were generated, but the actual PR diff and file contents were not inspected/validated here, so I cannot reliably attest that there are no merge-blocking issues.
• All changed files, especially src/core/command-generation/adapters/trae.ts and registry wiring in src/core/command-generation/registry.ts
