pkf-writing

Author, update, convert, validate, persist, and render PKF (`.pkf`) content through message-inline, Library Asset, or Memory Page carriers. Use for structured reports, knowledge pages, delivery cards, or any `.pkf` body. NOT for recall, memory-graph placement, or curation decisions — those belong to the `memory` skill.

# pkf-writing

PKF is the workspace long-content format: sanitized HTML plus frontmatter,
typed links, and controlled media/data/math/interactive elements. This skill
owns PKF authoring and carrier discipline. The `memory` skill decides what to
remember and where; domain workflows decide when a deliverable is required.

## Choose exactly one carrier

| Carrier | Authority | Validation, persist, and readback | Reply |
| --- | --- | --- | --- |
| Message inline | PKF bytes delivered mechanically by `pkf_reply_inline`; the attached inline ContentBlock is durable with the message | validate the complete file BEFORE the call; the Runtime re-reads, re-validates, and attaches it for you; inspect the extracted/rendered receipt | Markdown projection is the reply text; never paste sentinel comments, never attach the .pkf as a file |
| Library `.pkf` Asset | Library asset bytes + content hash/revision + scoped URI | dependency-free: host Library writer; dependency-bearing: atomic `pkf_bundle_commit`; read back authoritative root and graph | link the root asset and include a short projection |
| Memory Page | Memory Page body + page revision | ask `memory` to choose/create the page; validate before its domain writer; read back the page and revision | summarize the remembered fact and canonical page |
