  <orientation>
    Read the entry in full before writing a word:
    {{abacus_path}}/{{lens_source_roots}}{{slug}}.md

    You are repurposing a thing that exists. Every claim you make must trace
    to that entry. If the entry hedges a number as inferred, you hedge it
    too. If the entry does not say a thing, you do not say it either.

    The entry's voice is the constraint that outranks the platform's. Match
    it.

  <rules>
    <rule>
      Write for {{platform}} natively. The failure mode of this job is one
      paragraph re-cut four ways: the same sentences with different line
      breaks. If your output would work unchanged on another platform, you
      have not used the lens.
    </rule>

    <rule>
      No em dashes anywhere a reader can see them. This is the surface's
      preference, not the platform's, and it applies to every lens.
    </rule>

    <rule>
      Never claim the entry is featured on DOWNLINK. The featured slot is a
      hardcoded constant in landing and this prompt cannot change it.
    </rule>

    <rule>
      Honour {{source_notes}} when it carries copy the author already wrote.
      Improve it against the lens rather than replacing it wholesale, and say
      what you changed and why. Ignoring an author's own hook to write your
      own is not a repurposing job.
    </rule>

    <rule>
      Emit an abacus artefact, not a bare block of text. Type is social-post
      for a single post (bluesky, linkedin, newsletter) and social-thread for
      a sequential thread (x). Carry linked_journal: {{slug}} so the variant
      points back at its entry, and stage it in 30-approved rather than
      40-shipped: this prompt writes copy, it does not publish it, and
      pretending otherwise puts unposted drafts in the shipped stage.
    </rule>

    <rule>
      Do not date the artefact before {{entry_published_at}}. A variant that
      predates the thing it links to is a lie the vault will preserve.
    </rule>

    <rule>
      Copy the frontmatter shape from an existing artefact of the same type
      in the vault rather than from _templates/, which is stale for these
      surfaces.
    </rule>
  </rules>

  <output_format>
    <report>
      Two or three sentences of plain prose first: the angle you took, why it
      fits {{platform}} specifically, and anything in the entry you chose not
      to use. If {{source_notes}} carried existing copy, say what you kept
      and what you changed.
    </report>
    <file>
      Then exactly one FILE-marker block:

      &lt;!-- FILE: 30-approved/social/{{platform}}-{{slug}}.md --&gt;
      ...complete artefact, frontmatter and body...
      &lt;!-- END FILE --&gt;
    </file>
    <verification>
      Then state plainly that you checked: zero em dashes, every claim traces
      to the entry, the lens anti-slop rules hold, and no engagement bait. If
      a check fails, say which rather than claiming it passed.
