[11.4.0] - 2026-05-20 - "Mercury MCP, Photopea Embeds, and Codex Bundle Names"
Installable skill library update for Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, and related AI coding assistants.

- Workflows: docs/users/workflows.md
This release merges PR #598 and PR #601 through the maintainer workflow, fixes issue #597 by shortening Codex bundle plugin identifiers, and reduces antivirus false-positive risk in the Linux privilege-escalation guidance from issue #600.
New Skills
- mercury-mcp - lookup reference for Mercury MCP tools covering messages, threads, tasks, automations, agent context, and admin-scoped team graph tools.
- photopea-embedded-editor - web-app integration guide for embedding Photopea with
photopea.js, file loading, scripting, exports, layers, text, selections, and template editing patterns.
Improvements
- Codex bundle names - generated Codex bundle plugins now use compact
agyb-*names while preserving existing repo-local source directories, keeping qualified skill names within the 64-character loader limit. - bundle regression tests - adds coverage that every generated Codex bundle plugin name and
plugin:skillqualified name stays within the 64-character limit. - security skill false-positive reduction - replaces a pipe-to-shell LinPEAS example with download, inspect, chmod, and explicit execution steps for authorized labs.
- generated artifact sync - refreshes catalog, skill index, plugin mirrors, web assets, contributor credits, package metadata, and visible skill counts to
1,462+.
Who should care
- Codex CLI users can enable editorial bundles without losing valid skills to long qualified plugin names.
- MCP users get a compact Mercury tool reference for agent messaging, task tracking, and automations.
- Web app builders get a practical Photopea embedding guide for browser-based image editing workflows.
- Security learners and maintainers get safer documentation patterns that are less likely to trigger local antivirus heuristics.
