v0.52.1

🌟 Release Highlights

This release focuses on reliability and developer experience improvements — faster workflow dispatch, better error visibility, and more robust custom job support.

✨ What's New

• Faster workflow dispatch (#19414): dispatch_workflow now uses the GitHub API's return_run_details: true (Feb 2026) to get the run ID immediately after triggering a dispatch, eliminating the need to poll gh run list. Graceful fallback for older GitHub Enterprise Server deployments is included.

• Copilot inference access error surfacing (#19412): When a Copilot workflow fails due to an "Access denied by policy settings" error (token lacks inference access), the error is now clearly surfaced in agent failure issues and comments — no more silent failures or confusing diagnostics.

• Cache-memory scope validation (#19406): The cache-memory parser now validates the scope field against the supported enum values at compile time, catching misconfigured workflows before they reach runtime.

• Updated CLI versions (#19385): Codex updated to 0.107.0 and MCP Gateway updated to v0.1.7.

🐛 Bug Fixes & Improvements

• Stable caller workflow ID (#19408): GH_AW_CALLER_WORKFLOW_ID now uses the workflow's filename (e.g., my-workflow) instead of the mutable YAML name: display field. This fixes close-older-issues disambiguation breaking when workflows are renamed.

• Custom job runs-on support (#19407): Fixed a bug where runs-on values in custom jobs using array or object forms were silently dropped during compilation. All three forms (string, array, object) are now correctly emitted.

📚 Documentation

• Custom jobs field reference (#19404): The custom jobs documentation now includes a clear table of supported job-level fields (needs, runs-on, if, permissions, outputs, env, timeout-minutes, concurrency, continue-on-error, container, services), replacing a previously misleading "full job support" statement.
