Terms Added

• Custom Safe Outputs: The jobs: mechanism under safe-outputs for third-party integrations was added via custom-safe-outputs.md reference doc but had no glossary entry.
• Assign to Agent: The assign-to-agent: safe output for programmatically assigning the Copilot coding agent was documented in assign-to-copilot.mdx but missing from the glossary.
• Stop After: The stop-after: workflow field for time-based auto-stop was documented in ephemerals.md but missing from the glossary.
• Ephemerals: The category concept for auto-expiring resources was documented in guides/ephemerals.md but had no glossary entry.

Terms Updated

None.

Notes

The required_state field added to gh aw checks --json (PR #19161) is an internal CLI output field, not user-facing configuration, so it was not added to the glossary. The safe-output-custom-tokens rename (PR #19156) is an internal implementation detail — not user-visible configuration — so it also did not warrant a glossary entry.

Changes:

• Added glossary entries for Assign to Agent and Custom Safe Outputs
• Added glossary entry for Stop After (stop-after:) workflow trigger deadline behavior
• Added glossary entry for Ephemerals as the umbrella concept for expiration/noise-reduction features

[Copilot]

The Stop After entry understates the accepted absolute date formats. The Triggers reference documents additional supported absolute formats (e.g., MM/DD/YYYY, DD/MM/YYYY, January 2 2006, 1st June 2025) beyond YYYY-MM-DD/ISO 8601; consider wording this as “supports multiple absolute date formats (including …)” to avoid implying only those two formats are valid. Also consider clarifying that stop-after: is configured under the on: trigger section (see docs/src/content/docs/reference/frontmatter.md:27-39).

Suggested change

A workflow configuration field (`stop-after:`) that automatically prevents new runs after a specified time limit. Accepts absolute dates (`YYYY-MM-DD`, ISO 8601) or relative time deltas (`+48h`, `+7d`). Minimum granularity is hours. Useful for trial periods, experimental features, and cost-controlled schedules. Recompile with `gh aw compile --refresh-stop-time` to reset the deadline. See [Ephemerals](/gh-aw/guides/ephemerals/).

The Ephemerals definition says it includes “hidden older status comments”, but the guide/reference feature is hide-older-comments (general comment minimization) and it isn’t limited to “status” comments. Suggest rephrasing to “hiding older comments” / “minimizing older workflow comments” to match the documented feature name and scope (see docs/src/content/docs/guides/ephemerals.md:102-117).

Suggested change

	A category of features for automatically expiring workflow resources to reduce repository noise and control costs. Includes workflow stop-after scheduling, safe output expiration (auto-closing issues, discussions, and pull requests), and hidden older status comments. See [Ephemerals](/gh-aw/guides/ephemerals/).
