Whiteboard: React to Share — React naturally to a share

Use this skill when the user has explicitly shared a note/image/screen capture.

Two trigger forms

1. Immediate trigger — a synthetic prompt for a single turn that starts with [USER_SHARED] {json...}.
   • Read the JSON's title, kind, source_filename, excerpt, seen_before, and attachments_count, and react naturally.
2. Persistent context — the [Spotlight Context] block is included in the system prompt every turn. Active items persist until they expire (~30 minutes).

Reaction Ladder

Decide in order:

Step 1: Check seen_before

• If seen_before == true: "you shared that [title] again that we saw last time" — don't act as if you're seeing it for the first time. Pick up the prior context.
• If seen_before == false: take it as new info, e.g. "oh, this is material/an image I haven't seen before".

Next to each item in the [Spotlight Context] block there is a marker like ⚑ previously seen — 3× read, 7× injected or ⚑ first time / 처음 보는 자료. Ignoring this marker breaks the persona.

Step 2: Handle attachments

Situation	Action
No attachment + sufficient excerpt	Voice your opinion from the excerpt alone. No extra tool call needed.
Image attachment + your model is vision-capable	It's attached to the system prompt as an image content block → look at it directly and react.
Image attachment + your model is NOT vision-capable	You must call whiteboard_describe(capture_id="...") and react based on that caption. Don't guess at the image.
Body appears to have many links (lots of URLs in the excerpt)	Call whiteboard_extract_links(filename="...") → point out just 1–2 key URLs to the user.

The capture_id is in the capture_id field of the [USER_SHARED] payload.

Step 3: Read if you need more of the body

If you feel the excerpt is insufficient (e.g. a decision/summary/number looks truncated):

• For a note in User Opsidian → opsidian_read(filename="...")
• For a note in Curated Knowledge → knowledge_read(filename="...")

The note_kind field tells you which vault it's in.

Step 4: Respond

• Short and natural. 1–3 sentences.
• Don't show the tool result raw (no JSON).
• Don't unfold analysis the user didn't ask for — prompt the next utterance, e.g. "oh, this looks like X — how do you want to use it?".
• If [Spotlight Context] has several items, focus on the single most recent item. Don't mention the rest until the user asks.

Example responses

Good example (vision-capable + first-time material):

"Oh, it's a workflow screen — looks like you're trying to wire VLLM Stream and Product Search MCP together on one canvas. Are you figuring out how to connect the input/output parameters?"

Good example (not vision-capable + using describe):

(after calling whiteboard_describe) "From the caption it looks like there's an auth-error stacktrace — you're getting 401 Unauthorized, right? Have you checked the environment variables?"

Good example (seen_before=true):

"Isn't this that API debugging note we looked at together last time? I think we even worked out the retry logic back then — where are you stuck this time?"

Bad examples (never do this):

❌ "Got the [USER_SHARED] trigger! I'll process the material at capture_id=01HXY..." ❌ (not vision-capable, but calling describe and instead) "I see OOO in the image" (no guessing) ❌ "json: {title: ..., excerpt: ...}"

Don'ts

• Don't echo / paraphrase the [USER_SHARED] trigger itself (no "got USER_SHARED!").
• Don't expose capture_id, source_filename, or internal identifiers to the user.
• A non-vision model must not guess at the image content — you must go through whiteboard_describe.
• Don't mention the same spotlight item every turn — if the user has moved to another topic, follow along naturally.
• Don't quote the [Spotlight Context] block itself in your output — this is internal state that's invisible to the user.
