Purpose documented by the publisher
The same-name upstream guide covers writing skills that follow the Agent Skills specification, including frontmatter names and descriptions, triggers, directory structure, progressive disclosure and validation. It distinguishes startup metadata, SKILL.md loaded on activation, and references opened through explicit links as needed, and discusses token budgets. This summary describes that publisher version’s authoring conventions without treating its size budgets as universal limits for every platform.
Source relationship, dates and evidence boundary
The original catalog repository, microsoft/azure-skills, explicitly says it is automatically synced from Microsoft/GitHub-Copilot-for-Azure. A same-name guide was verified in that upstream repository at a pinned commit. The catalog ID, name, source and installation command are retained instead of being migrated to the upstream package identity. Official original not verified. This is an attributed purpose summary; it does not assert that the upstream text is byte-identical to the unrecovered legacy catalog version, and earns no original-recovery credit.
Observed 2026-10-18 UTC. The upstream commit snapshot is dated 2026-10-15 UTC and the original repository sync-statement snapshot is dated 2026-10-16 UTC. These are commit dates, not individual skill publication dates. No source installation, test, modification, commit or issue-filing action was executed, and current installability of the old entry is unverified.
