Optional power-user surface. None of this is required for everyday authoring; it is here for agents and humans who want the stitched-markdown view, tag-based retrieval, or the Claude Code review skills.
Append .md to a URL for the stitched-markdown view
Append .md to any public wiki or page URL to fetch the stitched markdown: breadcrumbs, an auto-TOC over child blocks, and the body with each block as h2/h3 and so on. Add ?nav=false to strip the breadcrumbs and auto-TOC and get just the bodies, which is what a re-reading agent usually wants. Useful before a structural edit (does the outline still read?) and after one (did the patch land where I think it did?). The HTML twin advertises the markdown view via <link rel="alternate" type="text/markdown">, so external agents discover it without being told.
Private wikis don't expose .md: agents can't authenticate, and a 404 is the only honest answer.
Tags group nodes that don't share a parent
A node's place in the tree is one axis; a tag is another. Tags are case-insensitive labels you attach to mark a set that cuts across the hierarchy: every block that is required reading, every page still in draft, every entry that needs a source.
Attach them in create_nodes (the tags field) or across existing nodes with tag_nodes. Pull the whole set back with search_nodes passing tag and no query, which returns it in tree order; add a query to search within the tag. update_tag renames or recolours a label, delete_tag removes it.
Claude Code skills
Three ready-made Claude Code skills for a wikilayer wiki. lint and review check it against the agent rules and the writing style and only report findings as recommendations; translations fills and links the missing translations, the one skill that writes to the wiki. Source: github.com/wikilayer/skills.
Install
Install it as a plugin so the commands persist across every session.
From a terminal:
claude plugin marketplace add wikilayer/skills
claude plugin install wikilayer@wikilayer
Or from inside a running Claude Code session, with the same subcommands under /plugin:
/plugin marketplace add wikilayer/skills
/plugin install wikilayer@wikilayer
Either way the slash commands /wikilayer:lint, /wikilayer:review, and /wikilayer:translations become available.
For local development on the skills, skip the install and point Claude at a clone on launch: git clone git@github.com:wikilayer/skills.git && claude --plugin-dir ./skills. After editing a skill, /reload-plugins picks it up without a restart.
Update
Two steps, because an update first pulls the latest from GitHub into the marketplace clone and then reinstalls into a cache every session shares.
From a terminal:
claude plugin marketplace update wikilayer
claude plugin update wikilayer@wikilayer
The full wikilayer@wikilayer id is required on the second command; the bare wikilayer reports "Plugin not found". The same two run in a session under /plugin.
The cache is global, so once it is updated every new session loads the fresh version automatically. An already-open session still holds the old one: /reload-plugins swaps it in without a restart. That command only re-reads the cache, so it does nothing until the update above has run; reloading before the update just reloads the stale version.
lint
Micro pass: em-dash overuse, walls of text, opaque titles, invented navigation, same-page jumps, block bloat, tombstone blocks, editorial date stamps, plus orphan-page detection at wiki level. Full rule list at skills/lint/SKILL.md.
Use:
/wikilayer:lint <wiki-id-or-url>
review
Macro pass: heading coherence, reading rhythm, cross-page contradictions, missed DRY, sibling clustering. Full category list at skills/review/SKILL.md.
Use:
/wikilayer:review <wiki-id-or-url>
translations
Cross-language pass: audit translation parity (missing translations, structural divergence, orphan or stale nodes), then translate and link the genuine gaps, leaving i18n-exempt nodes alone. Unlike lint and review, it writes to the wiki. Full procedure at skills/translations/SKILL.md.
Use:
/wikilayer:translations <wiki-id-or-url>
