colophon-crosslink

name	colophon-crosslink
description	Add cross-references between colophon posts — wikilinks and "related posts" — so entries connect to each other. Use when the user asks to link posts together, add related/see-also links, or wire up internal references on their colophon blog.

Cross-link colophon posts

colophon resolves [[wikilinks]] across every source at build time (an unresolved link degrades to plain text). Use them to connect posts instead of inventing URLs.

When to use

The user wants to add internal links / related-post references between existing entries.

Requirements

This skill drives the colophon CLI. Before the first command, confirm it's installed:

command -v colophon || echo "colophon not found"

If it's missing, stop and offer the install — don't install it silently: go install github.com/jmylchreest/colophon/cmd/colophon@latest (or a release binary). Proceed only once it's on PATH.

Workflow

1. List the candidate targets (and their tags, to find relevant ones):

   colophon posts --json                 # every entry: slug, title, tags, type
   colophon posts --tag <topic>          # entries on a related topic
   

2. Pick genuinely related entries — overlapping tags or subject matter, not every post. Prefer 2–5 strong links over a dump.

3. Add the links in the source file(s):

   • Inline, where the text references another post: … as covered in [[Raft leader election]] … (link by the target's title or slug; [[title|custom text]] sets the anchor text).
   • Or a trailing section:

     ## Related
     - [[Raft leader election]]
     - [[Designing for partition tolerance]]
     

4. Verify they resolve. Rebuild and check none fell back to plain text:

   colophon serve --open=<slug>
   

   An unresolved [[link]] means the target title/slug didn't match — fix the reference.

Guardrails

• If colophon isn't installed, surface the install command and ask — never install it silently.
• Make link text describe the destination (the target's title/topic), never "click here" or a bare slug — this is both better UX and an accessibility requirement.
• Only link to entries that actually exist (from colophon posts). Don't invent targets.
• Don't over-link; relevance over volume. Keep edits minimal and preserve voice.
