Agent Skill Manager v0.0.3

Changes in 0.0.3

Released 2026-09-08.

Changed

• Load child directories when expanded instead of walking every skill's file tree during the initial scan.
• Read frontmatter in 4 KiB blocks with a 64 KiB limit instead of loading the entire Markdown file for metadata.
• Move collection JSON encoding, decoding, and file I/O off the main actor. Serialize saves and use a Set to deduplicate imported IDs.
• Filter and sort the collection once per view body evaluation.

Fixed

• Keep SKILL.md and README.md available when a directory exceeds the 500-entry display limit. Show notices for omitted entries, cycles, depth limits, and read failures.
• Discard stale child listings and reload the selected document after refresh.
• Keep the last successfully saved collection visible if a later queued write fails. Reject exports that target the active collection file or a symlink alias.
• Handle UTF-8 and frontmatter delimiters across read boundaries, including a closing delimiter at the exact 64 KiB limit.
• Separate the installed-skill preview card from the split divider and clip its content and border to the rounded corners.
• Fill the application icon canvas with an opaque background.

Performance measurements

• On an Apple M4, release-build medians over seven runs reduced the nested-directory scan from 24.234 ms to 1.364 ms and metadata scanning for a 2.5 MB Markdown body from 20.215 ms to 0.091 ms.
• Reading and decoding 10,000 JSON records showed no improvement. Source-preview and scroll-policy changes remain deferred pending UI profiling.
• Add reproducible benchmarks and measurement details. These numbers measure filesystem work, not UI frame times.

Installation

Universal macOS app (Apple silicon and Intel), macOS 13+.

Open the DMG and drag Agent Skill Manager into Applications.
This app is ad-hoc signed, not Apple-notarized. Only open it if you trust this repository and release. Prefer System Settings > Privacy & Security > Open Anyway after attempting to launch.

If needed, remove quarantine from this app only after copying it into Applications:

xattr -dr com.apple.quarantine "/Applications/Agent Skill Manager.app"

This removes the downloaded-app quarantine protection for this app; it does not notarize it or disable Gatekeeper system-wide.
SHA-256 checksums are included alongside the DMG.

Agent Skill Manager v0.0.2

Changes in 0.0.2

Released 2026-09-07.

Changed

• Scan shared skill folders once per refresh, even when Agent and Claude entries link to the same folder.
• Cache document text and parsed Markdown. Check file attributes before reusing cached content.
• Skip repeated automatic refreshes within three seconds. Manual refresh still scans immediately.
• Load the collection and parse Markdown off the main thread.
• Configure scrollbars after content updates instead of traversing every window on each AppKit update.
• Show Markdown over 128 KB as source to avoid expensive rich-text layout. The text preview limit remains 2 MB.
• Load local preview images off the main thread and ignore results from cancelled document views.

Fixed

• Display the supplied Claude brand icon in the sidebar using an explicitly loaded vector resource.

Development

• Add a script to measure process launch to the first visible window.
• Record release changes in this file and use the matching version section for GitHub release notes.
