+# Copilot fetch X
+
+Fetch the content of an X (Twitter) post through Copilot Plus.
+
+## How to run
+
+Find the absolute path to this SKILL.md file on disk, then run the script next
+to it that matches the operating system. No extra runtime is needed — `sh`
+(macOS/Linux) and `cmd`/PowerShell (Windows) are always present.
+
+On macOS or Linux:
+
+```bash
+sh "/absolute/path/to/this/skill/directory/fetch-x.sh" "<x-or-twitter-url>"
+```
+
+On Windows, run the `.cmd` wrapper. In PowerShell you must prefix it with the
+call operator `&` (PowerShell treats a quoted path on its own as a string and
+won't run it); from cmd, run the quoted path without the `&`:
+
+```powershell
+& "/absolute/path/to/this/skill/directory/fetch-x.cmd" "<x-or-twitter-url>"
+```
+
+Both print the result to stdout.
+
+## If Copilot Plus is not active
+
+If the script exits saying Copilot Plus is unavailable, do NOT retry it. Do what
+the message says: fall back to your own equivalent built-in capability to handle
+the request when you have one (otherwise tell the user it's unavailable) — never
+refuse or block the user. Only mention upgrading or renewing Copilot Plus when
+the script's message explicitly invites it, and keep any such note short and
+friendly.

+description: Create and edit JSON Canvas (.canvas) files with valid nodes, edges, groups, colors, layout, IDs, and referential integrity. Use for Obsidian Canvas files, visual maps, flowcharts, project boards, or any request involving the JSON Canvas format.
+license: MIT
+metadata:

+---
+
+# JSON Canvas
+
+Follow JSON Canvas 1.0. A <code>.canvas</code> document contains top-level
+<code>nodes</code> and <code>edges</code> arrays.
+
+## Workflow
+
+1. Parse the existing JSON before editing it.
+2. Generate a unique lowercase 16-character hexadecimal ID for each new node
+   or edge.
+3. Position nodes without overlap and preserve intentional existing layout.
+4. Point every edge at existing node IDs.
+5. Serialize valid JSON and run the validation checklist below.
+
+## Nodes
+
+Every node requires <code>id</code>, <code>type</code>, <code>x</code>,
+<code>y</code>, <code>width</code>, and <code>height</code>.
+
+| Type | Required content | Purpose |
+| --- | --- | --- |
+| <code>text</code> | <code>text</code> | Markdown content |
+| <code>file</code> | <code>file</code> | Vault file; optional <code>subpath</code> |
+| <code>link</code> | <code>url</code> | External URL |
+| <code>group</code> | none | Visual container; optional label/background |
+
+Array order controls z-index: earlier nodes are behind later nodes. Coordinates
+may be negative. Position is the top-left corner, x increases right, and y
+increases down.
+
+~~~json
+{
+  "id": "6f0ad84f44ce9c17",
+  "type": "text",
+  "x": 0,
+  "y": 0,
+  "width": 360,
+  "height": 180,
+  "text": "# Main idea\n\nDetails",
+  "color": "5"
+}
+~~~
+
+Use actual JSON newline escapes in text values. Do not double-escape them into
+literal backslash-n text.
+
+## Edges
+
+Every edge requires <code>id</code>, <code>fromNode</code>, and
+<code>toNode</code>. Optional sides are <code>top</code>, <code>right</code>,
+<code>bottom</code>, or <code>left</code>. Optional ends are <code>none</code>
+or <code>arrow</code>.
+
+~~~json
+{
+  "id": "0123456789abcdef",
+  "fromNode": "6f0ad84f44ce9c17",
+  "fromSide": "right",
+  "toNode": "a1b2c3d4e5f67890",
+  "toSide": "left",
+  "toEnd": "arrow",
+  "label": "leads to"
+}
+~~~
+
+## Colors and layout
+
+A color is a hex string or preset <code>"1"</code> through
+<code>"6"</code>. Presets deliberately do not define exact hex colors. Leave
+50–100 px between nodes, 20–50 px padding inside groups, and align to a simple
+grid when creating a new layout.
+
+## Validation checklist
+
+- JSON parses successfully.
+- IDs are unique across nodes and edges.
+- Every <code>fromNode</code> and <code>toNode</code> exists in
+  <code>nodes</code>.
+- Each node type has its required content field.
+- Sides, ends, and colors use allowed values.
+- Nodes do not unintentionally overlap and group children sit inside bounds.
+
+Read [Examples](references/EXAMPLES.md) for complete connected and grouped
+canvases.

+
+## Filters and properties
+
+Filters may be a single expression or recursively nested <code>and</code>,
+<code>or</code>, and <code>not</code> objects. Property namespaces are:
+
+- note properties: <code>status</code> or <code>note.status</code>
+- file metadata: <code>file.name</code>, <code>file.path</code>,
+  <code>file.folder</code>, <code>file.ctime</code>, <code>file.mtime</code>,
+  <code>file.tags</code>, <code>file.links</code>, and
+  <code>file.backlinks</code>
+- formulas: <code>formula.days_until_due</code>
+
+Use <code>file.hasTag()</code>, <code>file.hasLink()</code>,
+<code>file.hasProperty()</code>, and <code>file.inFolder()</code> for indexed
+file relationships. The <code>this</code> value refers to the Base itself, the
+embedding note, or the active file depending on where the Base is rendered.
+
+## Formula rules
+
+- Guard optional properties with <code>if()</code>.
+- Date subtraction returns a Duration, not a number. Access
+  <code>.days</code>, <code>.hours</code>, or another numeric field before
+  calling number methods such as <code>.round()</code>.
+- Every <code>formula.X</code> used by a view or property configuration must
+  have a matching <code>X</code> entry under <code>formulas</code>.
+- Wrap formulas containing double quotes in YAML single quotes.
+- Quote YAML strings containing special characters, especially colons and
+  leading punctuation.
+
+Read [Functions reference](references/FUNCTIONS_REFERENCE.md) for function and
+type-specific operations, and [Examples](references/EXAMPLES.md) for complete
+task-tracker and daily-notes Bases.
+
+## Validation checklist
+
+- The document parses as YAML and has a <code>views</code> list.
+- View <code>order</code>, <code>groupBy</code>, and summaries reference defined
+  note, file, or formula properties.
+- Formula quoting is balanced and duration math accesses a numeric field.
+- Embedded view names match exactly: <code>![[My Base.base#View Name]]</code>.

+
+# Obsidian CLI
+
+Use the CLI only for behavior that depends on Obsidian's running application,
+indexes, settings, command registry, or developer runtime. Use normal shell
+filesystem tools for ordinary file reads, writes, directory listing, and text
+search.
+
+## Capability probe and fallback
+
+Copilot exposes the terminal-capable executable from the running Obsidian
+installation as <code>COPILOT_OBSIDIAN_CLI</code> when it can resolve one.
+Prefer that exact path over <code>obsidian</code> from <code>PATH</code>, and
+always invoke it as a quoted executable rather than constructing a command
+string. Before relying on the CLI, probe it using the active shell:
+
+~~~bash
+obsidian_cli="${COPILOT_OBSIDIAN_CLI:-obsidian}"
+"$obsidian_cli" version
+~~~
+
+~~~powershell
+$obsidianCli = if ($env:COPILOT_OBSIDIAN_CLI) { $env:COPILOT_OBSIDIAN_CLI } else { "obsidian" }
+& $obsidianCli version
+~~~
+
+A command being present on PATH is not sufficient: the probe must exit
+successfully. Use the selected executable in place of <code>obsidian</code> in
+the examples below, resolving it again in a later shell call when necessary. If
+the probe fails, continue with ordinary filesystem tools where they can satisfy
+the request. Briefly tell the user only when the missing runtime capability
+matters. Do not install Obsidian, change PATH, register the CLI, or raise the
+plugin's minimum Obsidian version on the user's behalf.
+
+The CLI requires a compatible Obsidian installer and a running app. Commands
+can differ by version, so inspect live help before using a command whose syntax
+is not already established:
+
+~~~bash
+obsidian help <command>
+~~~
+
+When a request truly needs the runtime capability and the probe fails, tell the
+user to open Obsidian and enable **Settings → General → Command line
+interface** using a compatible installer. Leave registration and any platform
+repair steps to the user.
+
+## Target precisely
+
+Put <code>vault=&lt;name-or-id&gt;</code> before the command whenever the vault is
+known. Use <code>path=</code> for an exact vault-relative path. Use
+<code>file=</code> only when Obsidian's wikilink-style name resolution is
+desired. Do not rely on the active vault or active file when a precise target
+is available.
+
+~~~bash
+obsidian vault="My Vault" backlinks path="Projects/Plan.md" format=json
+~~~
+
+Parameters use <code>name=value</code>; boolean flags have no value. Quote
+values containing spaces or shell-special characters.
+
+## High-value indexed and configured operations
+
+Use live help for exact parameters, then prefer these families when they add
+meaning beyond raw files:
+
+- Configured daily notes: <code>daily</code>, <code>daily:path</code>,
+  <code>daily:read</code>, <code>daily:append</code>,
+  <code>daily:prepend</code>.
+- Typed properties and parsed metadata: <code>properties</code>,
+  <code>property:read</code>, <code>property:set</code>,
+  <code>property:remove</code>, <code>tags</code>, <code>tag</code>, and
+  <code>aliases</code>. Supply a <code>type=</code> to
+  <code>property:set</code> when the property is not plain text.
+- Tasks: <code>tasks</code> for indexed listing and <code>task</code> with a
+  stable <code>ref=path:line</code> or exact file/line for status changes.
+- Link graph: <code>backlinks</code>, <code>links</code>,
+  <code>unresolved</code>, <code>orphans</code>, and <code>deadends</code>.
+- Bases: <code>bases</code>, <code>base:views</code>, and
+  <code>base:query</code>. Prefer <code>format=json</code> for structured agent
+  consumption.
+- Templates: <code>templates</code> and <code>template:read ... resolve</code>
+  when configured template resolution is required.
+- Live workspace state: <code>tabs ids</code> lists the currently open tabs and
+  their IDs, while <code>workspace ids</code> shows the workspace tree and its
+  item IDs.
+- Link-aware refactors: <code>move</code> and <code>rename</code> when the vault
+  setting to update internal links should be honored.
+
+### Inspect open notes
+
+When the user asks about notes currently open in Obsidian:
+
+~~~bash
+obsidian vault="My Vault" tabs ids
+obsidian vault="My Vault" workspace ids
+~~~
+
+Use <code>tabs ids</code> as the source of truth for open tabs. Keep entries
+verbatim and classify them only when the output provides enough evidence:
+
+- a Markdown note has an explicit vault path ending in <code>.md</code>
+  (case-insensitive)
+- another file-backed tab has an explicit vault path with a different extension
+- a non-file view, such as search, graph, settings, or a plugin view, has no
+  vault path
+
+Do not infer a path from a display title, view type, or tab ID, and do not
+discard entries that cannot be classified. For a request about open notes,
+extract the Markdown paths while retaining the other tabs as workspace context.
+Use <code>workspace ids</code> when tab groups or workspace hierarchy matter. Do
+not substitute <code>recents</code>, which includes files that are no longer open.
+
+If the tab output does not expose paths or view types clearly, correlate its tab
+IDs with this read-only, structured workspace query:
+
+~~~bash
+obsidian vault="My Vault" eval code='JSON.stringify((()=>{const tabs=[];const active=app.workspace.getMostRecentLeaf();app.workspace.iterateAllLeaves(leaf=>{const path=leaf.view.file?.path??null;tabs.push({id:leaf.id,title:leaf.getDisplayText(),viewType:leaf.view.getViewType(),path,kind:path===null?"view":path.toLowerCase().endsWith(".md")?"markdown":"file",active:leaf===active})});return tabs})())'
+~~~
+
+The workspace query also returns sidebar and floating leaves. Only call an entry
+an open tab when its ID appears in <code>tabs ids</code>; retain query-only
+entries separately as workspace context. Preserve tab entries that have no
+matching workspace entry instead of guessing their identity.
+
+If the user asks for the single currently focused note and the tab output does
+not identify it, use a read-only app query:
+
+~~~bash
+obsidian vault="My Vault" eval code="app.workspace.getMostRecentLeaf()?.view.file?.path ?? ''"
+~~~
+
+Use normal filesystem tools only for explicit paths returned by Obsidian, and
+choose a reader appropriate to the file type. Do not read every open note when
+paths or titles alone answer the request.
+
+## Obsidian and plugin commands
+
+<code>commands</code> lists registered command IDs, including commands provided
+by plugins. Filter by an ID prefix, then execute the selected command with
+<code>command id=&lt;command-id&gt;</code>. Never guess a command ID when it can be
+discovered. Do not execute a discovered command whose effect is prohibited by
+the host-session rules below.
+
+~~~bash
+obsidian vault="My Vault" commands filter="my-plugin:"
+obsidian vault="My Vault" command id="my-plugin:run-action"
+~~~
+
+## Plugin and theme development
+
+Use the CLI as the first choice for runtime verification after the normal build
+or test command has produced artifacts:
+
+1. For a plugin other than Copilot, reload with
+   <code>plugin:reload id=&lt;plugin-id&gt;</code> when needed. Never reload the
+   Copilot plugin from a Copilot-hosted agent session.
+2. Inspect <code>dev:errors</code> and <code>dev:console level=error</code>.
+3. Verify UI state with <code>dev:screenshot path=...</code>,
+   <code>dev:dom selector=...</code>, and <code>dev:css selector=...</code>.
+4. Use <code>dev:mobile on</code> only when mobile emulation is relevant, and
+   turn it off afterward.
+
+Read-only <code>eval</code> and <code>dev:cdp</code> queries are appropriate for
+state that the documented inspection commands cannot expose. Keep expressions
+small and return serializable values. Treat any expression or CDP call that
+mutates application state as a risky operation requiring explicit user intent.
+
+## Preserve the host session
+
+Never reload or restart the Obsidian app or window from an agent session. Never
+reload, disable, or uninstall the Copilot plugin that is hosting the agent. In
+particular, do not use:
+
+- any CLI command that reloads or restarts the app, window, or renderer
+- any plugin reload, disable, or uninstall operation targeting Copilot
+- any restricted-mode change
+- a command ID, JavaScript expression, or CDP call that performs an equivalent
+  app, window, renderer, or Copilot-plugin teardown
+
+These actions terminate the in-flight agent and can discard its work. This is a
+hard prohibition, not a confirmation-gated operation. If verification requires
+one, finish all non-destructive checks and tell the user to perform the reload
+manually after the agent session has ended.
+
+## Risky operations require explicit intent
+
+Do not perform the following merely because they are available:
+
+- permanent deletion
+- local-history or Sync restoration
+- publishing or unpublishing
+- plugin or theme installation/uninstallation
+- mutating JavaScript evaluation or CDP calls
+
+Confirm that the user's request clearly authorizes the exact target and effect.
+Prefer reversible variants, such as trash-backed deletion, when they satisfy
+the request. Explicit intent does not override the host-session prohibition
+above.
+
+## Exclusions
+
+Do not teach or use the TUI, clipboard output, undocumented flags, platform
+registration repairs, or CLI equivalents of generic filesystem operations in
+this skill.

+# Obsidian Markdown
+
+Use Obsidian-specific syntax accurately. Do not spend tokens explaining ordinary
+CommonMark or GFM unless the user asks.
+
+## Workflow
+
+1. Preserve existing frontmatter keys and formatting when editing a note.
+2. Use wikilinks for vault notes and Markdown links for external URLs.
+3. Use embeds, callouts, properties, tags, comments, and block references only
+   when they improve the requested note.
+4. Check link targets, YAML validity, and block IDs after editing.
+5. Read the focused reference file when the task needs more syntax detail.
+
+## Wikilinks and block references
+
+~~~markdown
+[[Note Name]]
+[[Note Name|Display Text]]
+[[Note Name#Heading]]
+[[Note Name#^block-id]]
+[[#Heading in this note]]
+
+This paragraph is addressable. ^block-id
+~~~
+
+Put a block ID on its own line after a list or quote block.

+
+~~~markdown
+![[Note Name]]
+![[Note Name#Heading]]
+![[image.png|300]]
+![[document.pdf#page=3]]
+~~~
+
+See [Embeds](references/EMBEDS.md) for media, PDF, and query forms.
+
+## Callouts
+
+~~~markdown
+> [!warning] Custom title
+> Important content.
+
+> [!faq]- Collapsed by default
+> Foldable content.
+~~~
+
+See [Callouts](references/CALLOUTS.md) for types, aliases, folding, and nesting.

+related: "[[Other Note]]"
+---
+~~~
+
+Quote wikilinks used as YAML values. See
+[Properties](references/PROPERTIES.md) for supported property types and tag rules.
+
+Use <code>#nested/tag</code> for inline tags. Hide content from reading view with

+description: Publish, update, or withdraw an existing Markdown note through OpenArtifacts' host-owned review flow. Use when the user asks to publish, share, update, delete, remove, or withdraw an OpenArtifacts page.
+metadata:
+  copilot-enabled-agents: claude, codex, opencode
+  copilot-builtin-version: "1"
+---
+
+# Publish Markdown to OpenArtifacts
+
+Require one existing Markdown source file. When the user asks to delete, remove, or
+withdraw its current OpenArtifacts page, do not generate HTML. Run the host wrapper with
+only the vault-relative source-note path. Obsidian reads the note's current identity
+and opens its existing management modal; the user alone chooses Update or Delete.
+Never tell the user to delete the page at its public URL.
+
+For publishing or updating, finish a complete, self-contained,
+passive HTML document before asking Obsidian to review it. Render source-specific
+content such as Mermaid and Obsidian Bases into static HTML or SVG, embed images,
+and include no scripts, frames, forms, handlers, redirects, or external assets. Treat
+YAML frontmatter as note metadata: never render the raw frontmatter block as page
+content. The exact UTF-8 HTML must not exceed `10485760` bytes.
+
+Style the page from a theme file rather than improvising. Resolve the theme name in
+this order: `OPENARTIFACTS_THEME` from the environment when set, then a theme the
+user named in chat, then `research-memo`. Read
+`$OPENARTIFACTS_WORKSPACE_ROOT/.openartifacts/themes/<name>.md` when the
+user has authored that theme, otherwise `themes/<name>.md` next to this file. Follow
+it exactly: tokens, type, scale, layout, components, and its theme-handling CSS, all
+inlined. If neither file exists, still publish with restrained defaults (system fonts,
+one accent, a readable measure, light and dark handled) and tell the user which theme
+was not found.
+
+Write those final bytes to a new unique `.html` file under
+`$OPENARTIFACTS_WORKSPACE_ROOT/.openartifacts/handoffs/`, creating that
+directory first when it does not exist. Do not show a prose substitute or ask
+for confirmation in chat. Instead run the host wrapper with exactly two
+vault-relative paths: the source note and the staged HTML.
+
+On macOS or Linux:
+
+```bash
+sh "/absolute/path/to/this/skill/directory/openartifacts-publish.sh" "Notes/source.md" ".openartifacts/handoffs/unique.html"
+```
+
+For withdrawal, omit the staged-HTML argument:
+
+```bash
+sh "/absolute/path/to/this/skill/directory/openartifacts-publish.sh" "Notes/source.md"
+```
+
+On Windows, use the `.cmd` wrapper (prefix it with `&` in PowerShell):
+
+```powershell
+& "/absolute/path/to/this/skill/directory/openartifacts-publish.cmd" "Notes/source.md" ".openartifacts/handoffs/unique.html"
+```
+
+Omit the staged-HTML argument on Windows for withdrawal as well.
+
+With only the source path, the wrapper blocks while Obsidian shows its host-owned
+Update/Delete management modal. With a staged HTML path, it blocks while Obsidian
+consumes the artifact and shows its source, title, and a link to a sandboxed
+local-browser rendering of the exact captured page. Obsidian rejects active or
+externally loaded content, prevents navigation from the browser preview, removes the
+original artifact, removes its temporary browser preview after review, and alone reads
+the current note identity to choose whether confirmation publishes or updates; never
+choose an action or document id.
+
+- `cancelled`: stop. No request was sent.
+- `regenerate`: create a new complete artifact and run the wrapper again. The
+  previous confirmation never applies to regenerated bytes.
+- `published` or `updated`: return the host-provided public URL verbatim.
+- `deleted`: report that the host withdrew the page and removed its note identity.
+- `failed`: if the host says to edit the staged file, address every listed issue in
+  that same file and retry exactly once. Otherwise, or if that retry fails, stop and
+  report the exact host message. Never invent a cause, change unrelated styling, create
+  another filename, bypass the review, or publish directly.

-# Publish Markdown to OpenArtifacts
+# Publish Markdown or HTML to OpenArtifacts
 
-Require one existing Markdown source file. When the user asks to delete, remove, or
-withdraw its current OpenArtifacts page, do not generate HTML. Run the host wrapper with
-only the vault-relative source-note path. Obsidian reads the note's current identity
-and opens its existing management modal; the user alone chooses Update or Delete.
-Never tell the user to delete the page at its public URL.
+Copilot supplies everything this skill needs through the environment:
+`$OPENARTIFACTS_WORKSPACE_ROOT` is the vault root, and `COPILOT_PLUS_LICENSE_KEY`
+is the credential the bundled wrapper sends. Do not read Copilot settings or credential
+files, print the key, install anything, or run Node, npm, npx, or the Obsidian CLI.
+
+If `COPILOT_PLUS_LICENSE_KEY` is unset or empty, stop before generating anything and tell
+the user: Publishing to OpenArtifacts needs a Copilot Plus license key. Add it in Copilot Settings and try again.
+
+## 1. Prepare the page
+
+### Existing Markdown note
+
+Read one existing Markdown source note. Treat YAML frontmatter as metadata, never as page
+content. Note its `openartifacts` property, or on older notes the `symposium` property:
+an `https://…/d/<docId>` value means the note is already published and this task updates
+that page; pass that `docId` to the wrapper. Compare document ids, not urls: an older
+`symposium.site` link and an `openartifacts.site` link with the same id are the same page.
+If either property holds any other value, or the two name different ids, stop and ask the
+user before touching them.
+
+Write complete UTF-8 HTML (at most `10485760` bytes) to a new file
+under `$OPENARTIFACTS_WORKSPACE_ROOT/.openartifacts/handoffs/`, creating
+the directory if needed. Preserve the note's content; render Obsidian-specific syntax such
+as wikilinks, callouts, embeds, Mermaid, and Bases into static HTML or SVG. CSS, scripts,
+and external resources are allowed and are published unchanged.
+
+Use the note's file name without `.md` as its page title. Convert the filename-derived title to
+title case while preserving recognizable acronyms and proper names. Put that title in both the HTML
+`<title>` and a visible `<h1>` above the rendered note body. If the user explicitly asks for no
+title, do not add the `<h1>`. Keep the HTML `<title>` as browser metadata, and preserve any
+authored opening heading as note content. Otherwise, if the rendered note body already starts with an
+equivalent `<h1>` containing the same visible title text, use that heading as the page-body title
+and do not add another heading. Preserve all remaining note content below it, and do not edit the
+source Markdown to add the heading. Keep normal text wrapping on the `<h1>` so long titles wrap
+naturally on narrow screens. Never truncate the title, hide its overflow, or apply single-line or
+ellipsis styling. The review and publish steps must use this same complete HTML file so its title
+and body match in preview and after publishing.
+
+Themes are optional. For a named theme, check
+`$OPENARTIFACTS_WORKSPACE_ROOT/.openartifacts/themes/<name>.md`, then
+`themes/<name>.md` next to this skill. Check each path independently. If neither
+exists, continue with readable defaults; a missing theme must never block publishing.
+The bundled `research-memo` is an optional example.
+
+### Existing HTML file
+
+For an existing local `.html` file, confirm that it exists and is at most
+`10485760` bytes. Pass that original HTML file path directly to
+the wrapper. Treat the file as the complete page: do not convert it to Markdown, and do
+not render, rewrite, or copy it into `.openartifacts/handoffs/`. Use its file
+name without `.html` as the wrapper title without changing the document's own title or
+visible content. Skip the Markdown frontmatter, generated-title, and theme instructions
+above. Check the HTML, including inline CSS, for every reference to a local file. Examples
+include relative `src`, `href`, `srcset`, `poster`, or CSS `url(...)` references.
+If any exist, keep the file unchanged; name each reference in the review message and say it
+will not load on the published page because only the HTML file is uploaded. This warning
+does not block publication: let the user make the file self-contained or approve publishing
+anyway. The original file remains user-owned; never delete the original HTML file.
 
-For publishing or updating, finish a complete, self-contained,
-passive HTML document before asking Obsidian to review it. Render source-specific
-content such as Mermaid and Obsidian Bases into static HTML or SVG, embed images,
-and include no scripts, frames, forms, handlers, redirects, or external assets. Treat
-YAML frontmatter as note metadata: never render the raw frontmatter block as page
-content. The exact UTF-8 HTML must not exceed `10485760` bytes.
-
-Style the page from a theme file rather than improvising. Resolve the theme name in
-this order: `OPENARTIFACTS_THEME` from the environment when set, then a theme the
-user named in chat, then `research-memo`. Read
-`$OPENARTIFACTS_WORKSPACE_ROOT/.openartifacts/themes/<name>.md` when the
-user has authored that theme, otherwise `themes/<name>.md` next to this file. Follow
-it exactly: tokens, type, scale, layout, components, and its theme-handling CSS, all
-inlined. If neither file exists, still publish with restrained defaults (system fonts,
-one accent, a readable measure, light and dark handled) and tell the user which theme
-was not found.
-
-Write those final bytes to a new unique `.html` file under
-`$OPENARTIFACTS_WORKSPACE_ROOT/.openartifacts/handoffs/`, creating that
-directory first when it does not exist. Do not show a prose substitute or ask
-for confirmation in chat. Instead run the host wrapper with exactly two
-vault-relative paths: the source note and the staged HTML.
-
-On macOS or Linux:
+## 2. Let the user review
+
+Tell the user the absolute path of the HTML file and that, subject to any relative-asset
+warning above, opening it in a browser shows the page as it will be uploaded; OpenArtifacts
+adds its own header and footer bylines when it serves the page. Then end your turn.
+
+Never publish in the same turn that generated the HTML. Publish only when a later
+message from the user clearly asks to publish this page. Treat anything else as feedback
+(revise the generated Markdown handoff and repeat this step; for existing HTML, relay the
+feedback and wait for the user to update the file, then repeat steps 1 and 2 before accepting
+publication approval) or as a cancellation. When unsure whether a message is an approval,
+ask once. Never simulate the user's approval.
+
+## 3. Publish
+
+Run the wrapper next to this SKILL.md with the HTML file, its filename-derived title, and
+the existing `docId` when updating a Markdown note. Run it as a shell command with your shell command tool (for example
+`Bash` in Claude Code, `shell` in OpenCode, `exec_command` in Codex). The command
+is shell syntax, not JavaScript or TypeScript: never pass it as the code of a
+code-execution tool.
+On macOS or Linux, the Markdown path uses its generated handoff:
 
 ```bash
-sh "/absolute/path/to/this/skill/directory/openartifacts-publish.sh" "Notes/source.md" ".openartifacts/handoffs/unique.html"
+sh "/absolute/path/to/this/skill/directory/openartifacts-publish.sh" publish "$OPENARTIFACTS_WORKSPACE_ROOT/.openartifacts/handoffs/unique.html" "Note title" [docId]
 ```
 
-For withdrawal, omit the staged-HTML argument:
+An existing HTML file uses its original path directly:
 
 ```bash
-sh "/absolute/path/to/this/skill/directory/openartifacts-publish.sh" "Notes/source.md"
+sh "/absolute/path/to/this/skill/directory/openartifacts-publish.sh" publish "/absolute/path/to/page.html" "Page title"
 ```
 
-On Windows, use the `.cmd` wrapper (prefix it with `&` in PowerShell):
+On Windows, use the `.cmd` wrapper (prefix with `&` in PowerShell):
 
 ```powershell
-& "/absolute/path/to/this/skill/directory/openartifacts-publish.cmd" "Notes/source.md" ".openartifacts/handoffs/unique.html"
+& "/absolute/path/to/this/skill/directory/openartifacts-publish.cmd" publish "$env:OPENARTIFACTS_WORKSPACE_ROOT/.openartifacts/handoffs/unique.html" "Note title" [docId]
 ```
 
-Omit the staged-HTML argument on Windows for withdrawal as well.
-
-With only the source path, the wrapper blocks while Obsidian shows its host-owned
-Update/Delete management modal. With a staged HTML path, it blocks while Obsidian
-consumes the artifact and shows its source, title, and a link to a sandboxed
-local-browser rendering of the exact captured page. Obsidian rejects active or
-externally loaded content, prevents navigation from the browser preview, removes the
-original artifact, removes its temporary browser preview after review, and alone reads
-the current note identity to choose whether confirmation publishes or updates; never
-choose an action or document id.
-
-- `cancelled`: stop. No request was sent.
-- `regenerate`: create a new complete artifact and run the wrapper again. The
-  previous confirmation never applies to regenerated bytes.
-- `published` or `updated`: return the host-provided public URL verbatim.
-- `deleted`: report that the host withdrew the page and removed its note identity.
-- `failed`: if the host says to edit the staged file, address every listed issue in
-  that same file and retry exactly once. Otherwise, or if that retry fails, stop and
-  report the exact host message. Never invent a cause, change unrelated styling, create
-  another filename, bypass the review, or publish directly.
+For an existing HTML file on Windows, replace the handoff path with the original absolute
+`.html` path and omit the `docId`.
+
+Success returns the same server receipt, `{"docId", "url", "version"}`, for either
+input. For a Markdown note, set its `openartifacts` frontmatter property to that `url`
+(create the frontmatter block if needed, keep every other property), remove a `symposium`
+property whose link has the same document id, and delete the generated HTML file from
+`.openartifacts/handoffs/`. For an existing HTML file, leave the source file
+unchanged. Then report the URL. Publishing the same Markdown note again updates the same page.
+
+On failure the wrapper prints the HTTP status and the server's message to stderr and
+exits 1. Report that message verbatim. Do not retry on your own, invent a cause, strip
+styling, or publish another way. For a 401, the license key was refused or the plan
+cannot publish; point the user at Copilot Settings. For `not_found` on an update, stop;
+do not create a replacement page unless the user explicitly asks.
+
+## 4. Withdraw
+
+For delete, remove, or withdraw requests, take the `docId` from an OpenArtifacts link the
+user supplies or the receipt URL reported earlier. Otherwise, read it with the same rules as
+step 1: `openartifacts` first, `symposium` on older notes, compared by document id, and
+stop to ask on any other value or on two properties naming different ids. If there is no link
+or property, say nothing is published. Otherwise tell the user the link will stop working and
+that copies people already saved cannot be recalled, then end your turn. On a clear yes, run
+the wrapper with `unshare <docId>`, remove each `openartifacts` or `symposium` property
+only when that property's own link has the same document id, and report that the page is gone.
+Never tell the user to delete the page at its public URL.
