kg-plan-processing

# KG Plan Processing Adds one item to the `planned/` work queue. This skill only *enqueues* — it never fetches a URL, never writes vault content, and never spawns `kg-writer`. Dispatching the queue (spawning one `kg-writer` agent per queued file, in parallel) is a separate, manual step done directly with the Agent tool per `.claude/agents/kg-writer.md`, not something this skill does. If there's no batch intent — the user just wants one URL processed right now — skip this skill entirely and invoke `kg-article-processing` (or `kg-note-writing` for a topic with no new source) directly instead. `planned/` lives at the repo root (sibling to `obsidian/`, `claude-skills/`), not inside the vault — it's a task queue, not vault content, so use plain filesystem tools (Read/Write/`ls`) on it, not the Obsidian MCP server. ## Workflow 1. Take the input: a URL (article or video) or a bare topic/entity name. 2. Check it isn't already queued or already processed — grep the URL/topic string against `planned/*.md`, `planned/done/*.md`, and (via the Obsidian MCP server) existing `Articles/`/`Videos/`/entity notes in the vault. If a match turns up, don't silently skip or silently requeue it — stop and ask the user what to do (AskUserQuestion), stating where the existing copy is (which file/note) and offering choices such as: skip (leave it as is, recommended default), queue it anyway (e.g. to force reprocessing), or view/open the existing item first. Proceed to step 3 only once they answer. 3. Derive a filename slug: for a URL, slugify the URL itself (strip scheme, replace non-alphanumerics with `-`); for a topic, slugify the topic name. Don't fetch the URL to get a title — that's `kg-writer`'s job when it's later dispatched, not this skill's. 4. Write `planned/<slug>.md` containing exactly one line — the URL or topic name, nothing else — per the one-liner format in `.claude/agents/kg-writer.md`. Create `planned/` if it doesn't exist yet. 5. Report the file written and, briefly, what it'll produce when processed (a new Article/Video note plus extracted entities, or a topic/concept enrichment). ## Notes - Multiple calls (one per URL) queue multiple files — this skill handles one item per invocation; queueing several items is just calling it several times. - This skill deliberately stops after writing the file. It does not check whether other items are already queued and does not suggest dispatching them — that's a separate decision the user makes.
