skills/sandwich-hime: a portable 0BSD Agent Skill for safe .sando authoring, composition, migration, review, debugging, and security work.
editors/vscode: the AGPL-3.0-only VS Code preview client for Hime-san's reusable Language Server Protocol implementation.

Language intelligence belongs to the canonical Hime-san compiler. The editor starts one himesan lsp --stdio process per trusted workspace folder and adds syntax highlighting, snippets, explicit project commands, and lifecycle UX. It does not download, install, upgrade, or phone home.

Preview compatibility

Agent Skill skill/v0.1.0: Hime-san v1.0.0-beta.1 and newer.
VS Code 0.1.0-preview.1: requires Hime-san v1.0.0-beta.2 and its advertised lsp-stdio feature.
Sando runtime remains independently versioned; Beta 2 tooling is compatible with sando/v1.0.0-beta.1.
The unchanged Skill and VS Code preview are verified compatible with the compiler and runtime v1.0.0-rc.1 release candidate.

Exact pinned installation order:

go get gamertan.com/sandwich-hime/sando@v1.0.0-rc.1
go install gamertan.com/sandwich-hime/cmd/himesan@v1.0.0-rc.1

Install the portable skill

Download sandwich-hime-skill-v0.1.0.zip and SHA256SUMS from the canonical Gitea skill/v0.1.0 release, verify the checksum, and extract the single sandwich-hime folder into one of these locations:

Codex user scope: $CODEX_HOME/skills/sandwich-hime (normally ~/.codex/skills/sandwich-hime).
Open Agent Skills project scope: .agents/skills/sandwich-hime.

The folder itself is the portable unit: SKILL.md, its 0BSD LICENSE, agent metadata, and the two routed references. Do not install the whole tooling repository as a skill. Restart or reload the agent host after extraction if it does not discover new skills dynamically.

Install the editor preview

The preview is intentionally a Gitea release asset, not a Marketplace or Open VSX listing. Verify its checksum, then run:

code --install-extension sandwich-hime-0.1.0-preview.1.vsix

The extension supplies syntax highlighting without trust. Its executable features require a trusted workspace and a separately installed compatible compiler; it never downloads Hime-san for you. The current release-candidate installation is Hime-san v1.0.0-rc.1.
