Summary

Tighten the existing create-issues-and-epics skill based on the LibreSign Unified Search epic publication and review.

• Require a GitHub capability preflight before publication approval, including issue types, native hierarchy and ordering, blocked-by relations, and effort/priority/project fields.
• Ask whether each proposed child is an independently verifiable deliverable instead of an acceptance criterion or internal refactor.
• Distinguish good first issue suitability from immediate readiness, including appropriately documented blocked newcomer tasks.
• Require reproducible fixtures and before/after methodology when drafting performance work.
• Reconcile the final GitHub state against the approved hierarchy, sibling order, dependencies, metadata and deliberate blanks before declaring publication complete.

Scope

Documentation-only update to the skill entrypoint and two existing references. No workflow executables, repository issue data, or other skills are changed.

Verification

• Confirmed the changes are limited to three skill Markdown files via the main...docs/harden-issue-epic-workflow comparison.
• Confirmed one commit ahead of main and no divergence.
• Git Signing MCP verified OpenPGP signature and author-matching DCO.
• Checked the existing entrypoint/frontmatter and in-memory edit anchors before committing.

Motivation

Addresses the repeated administrative reconciliation required after publishing LibreSign/libresign#9065 and avoids turning its particular implementation choices into universal skill rules.
