openpress

name	openpress
description	Use when operating an open-press workspace through CLI commands, discovering project status, validating/exporting/rendering/PDF/Word output, inspecting structure/issues, searching or safely replacing source text, routing pending @openpress-comment marker work to openpress-apply-comments, routing framework upgrade work to openpress-upgrade, or deciding which open-press skill owns a task.

open-press Core

open-press owns the tool surface and delivery boundaries. Use this skill first when the task involves the CLI, workspace status, generated output, or deciding which specialist skill should take over.

This skill is also the single source of truth for the source vs generated boundary. Other skills reference this section instead of re-listing paths.

Responsibilities

• Choose safe open-press CLI commands.
• Define the canonical source vs framework vs generated path boundary (see below).
• Inspect workspace state before broad edits.
• Open and manage the local workbench review loop.
• Route @openpress-comment marker work to openpress-apply-comments.
• Route package upgrade and migration work to openpress-upgrade.
• Point framework release work to docs/release-and-deploy.md; release maintenance is documentation, not an installed workspace skill.
• Route domain work to the owning skill.
• Require verification before declaring output ready.

Skill Routing

Skill	Owns
openpress	CLI, inspect/search/replace, source/generated boundary, validation/export/render/PDF/Word command choice, framework doctor, skill routing
openpress-upgrade	Package upgrades, skill refresh, migration-doc selection, workspace migration planning, source migration, QA checkpoint loop
openpress-create-pages	Creating or adding page-based artifacts: reports, proposals, papers, books, teaching notes, page Press Tree, first-pass theme, hierarchy, prose structure, captions, portable writing skill loading
openpress-create-slide	Creating or adding slide decks: slide Press Tree, slide-16-9 defaults, slide-style templates, reusable UI primitives, Tailwind semantic styling, deck structure, motion/assets discipline
openpress-apply-comments	Pending @openpress-comment marker workflow: list, apply, resolve, clear, verify
openpress-diagram-drawing	Diagram semantics: nodes, arrows, labels, states, figure text
openpress-deploy	Deploy config, preflight, dry run, public publish confirmation
Portable writing skills (chinese-ai-writing-polish, external project skills)	Language, tone, and genre rules. Loaded by openpress-create-pages when page content requires them.

Source Boundary (canonical)

Edit source, not generated output. This list is the single authoritative version; other skills link here.

Layer	Paths	Edit?
Workspace source	press/*/press.tsx, registered source roots/files (press/<slug>/chapters/** for MDX Press), press/<slug>/components/, press/<slug>/theme/, press/<slug>/media/, optional press/shared/, press/design.md, and the "openpress" field in workspace package.json	yes — skills
Skill source	skills/<name>/SKILL.md, .agents/skills/<user>/, .claude/skills/<user>/	yes — framework or user-authored skill rules
Framework source (this repo)	packages/core/, packages/cli/, apps/web/, root build config, framework docs/tests	yes — framework agents only
Framework dependency (downstream workspace)	node_modules/@open-press/core/, node_modules/@open-press/cli/	read-only during document work; fix upstream
Generated/cache	public/openpress/, dist-react/, .deploy/, .openpress/, .turbo/cache/	never hand-edit

If a workspace lacks press/*/press.tsx, it has runtime files but no Press Tree source yet. Route to openpress-create-pages for page-based artifacts or openpress-create-slide for slide decks.

If memory/AGENTS.md exists, read it before framework-level AGENTS.md; it usually marks a downstream workspace where press/ is git-ignored project content, not source you commit upstream.

Press Tree Render Boundary

• press/<slug>/press.tsx owns one rendered Press tree: <Press>, manuscript helpers such as <Toc> / <Sections>, and any custom frame components.
• <Press sources> owns MDX registration. The helper reads the registered source, not a hard-coded folder.
• <Press componentsDir> and <Press mediaDir> may be a path or path array. Prefer folder-local ./components / ./media; use press/shared/* only for intentionally shared source.
• <Frame> is the only core page primitive. Cover, TOC, openers, content pages, and back cover are all frame instances from the engine's perspective.
• <MdxArea> and helper wrappers such as <TocArea> are measurable content slots. TOC is implemented as a generated toc:<sourceId> chain, not as a reader/runtime special case.
• Page chrome belongs to workspace components. Headers, footers, running titles, page numbers, and TOC page layout must be implemented in the workspace Press tree or source-tree components; the reader runtime displays final HTML and must not paginate or patch page shell after export.

Workflow

1. Orient: read AGENTS.md, memory/AGENTS.md if present, and the relevant specialist skill.
2. Inspect before broad edits with inspect --json, search --json, or rg.
3. Route domain work to the owning skill instead of duplicating its rules.
4. Edit only source paths in the owning area (see boundary table).
5. Verify with the narrowest command that proves the claim.

Hot reload boundary

Vite Hot Reload covers React UI chrome (workbench panels, navigation, inspector) and framework CSS (packages/core/src/styles/ in this repo, or node_modules/@open-press/core/dist/ in downstream workspaces). It does not regenerate public/openpress/<slug>/document.json. So edits to MDX content, press/*/press.tsx, press/<slug>/components/**/*.tsx, package.json's "openpress" metadata, or any press/<slug>/theme/** rule that changes pagination capacity require a re-export before the workbench / public viewer shows the change:

npm run build              # validate + render (includes the export step)
# — or, for the inner export only, without the full Vite bundle step:
node engine/cli.mjs export .
# then refresh the browser

Pure CSS edits that don't move blocks are picked up by HMR — re-export is only required when content, pagination, or document.json metadata changes. After applying a non-CSS edit to press/, run npm run build before reporting "done"; if the user asks "why didn't my change show up?", check whether document.json was regenerated since the edit.

Starting A New Workspace

Starting a new artifact is owned by openpress-create-pages or openpress-create-slide.

The global create package is the low-level workspace bootstrapper:

npm create @open-press <target> -- --type slides

Creation skills call that command when they need a fresh package-based workspace shell. Slide skills keep and extend the generated slides Press; page skills replace it with the appropriate pages Press Tree, theme, source folders, and components. Inside an existing workspace, slide decks are added with open-press create <slug> --type slides. openpress does not own intake for new artifacts.

Before a framework release, verify the create surfaces still match core and the slide skill: @open-press/create and open-press create must both scaffold marker-only slide Presses, slide-style/manifest.json, registered slide-style/templates/*/slide.tsx, an active theme/default.css copied from slide-style/theme/default.css, slides/<id>/slide.tsx, and theme/ (not themes/). Run the create and CLI package tests after any template or core slides-folder contract change.

Use openpress for system lifecycle work on existing workspaces: doctor, validation, render, PDF/image/Word export, deploy dry-runs, and source search/replace. Use openpress-upgrade for package upgrades and workspace migrations.

Updating An Existing Workspace

Use openpress-upgrade when the user explicitly asks to upgrade, check for a new version, respond to an update notice, prepare before migration, apply migration notes, or verify migration QA. Do not run upgrade commands during ordinary writing/design/deploy work.

@openpress-comment Routing

Use openpress-apply-comments when the user asks to list, apply, resolve, clear, or inspect pending @openpress-comment markers. Keep this skill focused on the source boundary and command surface; the comment workflow lives in the dedicated workflow skill.

When To Read References

• Read references/cli-commands.md when choosing commands, using search/replace, or explaining verification depth.
• Read references/local-review.md when opening the workbench, using the inspector / page zoom / inline source editor, or coordinating visual review before export/deploy.

Safety Rules

• Preview broad replacements before applying them.
• Do not publish without explicit user confirmation naming the target (handled by openpress-deploy).
• Do not claim render, PDF, or deploy readiness without fresh command output.
