name: s4h-communication-medium-selection description: "Matches the message to the right channel and format — the same content in the wrong medium loses most of its effect. Triggers: 'which channel', 'email vs meeting', 'should this be async or sync', 'medium fit', 'how should I deliver this'."

Communication Medium Selection

The same content delivered through the wrong medium loses most of its effect. Bad news in Slack destroys trust. A complex decision in an email generates confusion. A routine update in a meeting wastes an hour. Medium selection is not a logistics question — it is a communication design decision that determines whether the message can land at all.

Your Process

Step 1: Message Goal What must the receiver do, feel, or understand as a result of this communication? Be specific. "Understand the situation" is not a goal. "Approve the budget by Friday" is. "Feel heard about the reorg" is.

Framing check: Confirm the message, the audience, and the goal before continuing. State what you've identified — the actual communication being designed and its key parameters — in one sentence, then use AskUserQuestion:

• Question: "I'm reading this as: [your one-sentence framing of the message, audience, and goal]. Is that right?"
• Header: "Framing"
• Options:
  • Yes — proceed — framing is correct
  • Adjust — one element is off; user will correct it before you continue
  • Reframe — different situation than read; incorporate the correction before proceeding

Step 2: Urgency How quickly must they act or respond? Hours, days, weeks? Urgency drives the sync vs async question more than any other factor.

Step 3: Emotional Weight Is this message carrying emotional content? Difficult news, a sensitive correction, a celebration, a request that requires trust, a change that affects someone's identity or security? Emotional weight requires channels that allow nuance and reaction.

Step 4: Complexity Does this require back-and-forth to resolve, or can it land cleanly in a single read? Complex decisions with multiple unknowns require synchronous dialogue. Clear information transfers can be async.

Step 5: Match to Medium Apply the selection logic:

• Difficult news / sensitive topic → sync verbal (in person or video)
• Complex decision requiring buy-in → meeting with written pre-read
• Simple update, no action required → async written (email or doc)
• Permanent record needed → written
• Emotional connection is the goal → video or in person
• Fast coordination, low stakes → messaging (Slack, etc.)
• Formal commitment → written with signature or named acknowledgment

Step 6: Choose Primary and Secondary Medium

Before narrowing: Show the complete set of candidate media that matched in Step 5 to the user first. Use AskUserQuestion:

• Question: "I've identified these candidate media: [list each matching channel from Step 5]. Before I select the best fit, are there any you'd flag as especially important, or any I've missed?"
• Header: "Prioritise"
• Options:
  • Proceed with your selection — the set looks right
  • Flag one — user will name a specific channel to include
  • Add a missing one — user will describe it

Select the primary channel. If the message needs reinforcement (complex, high-stakes, or high emotional weight), add a secondary: e.g., meeting followed by written summary.

Human Check-in

Before proceeding, use the AskUserQuestion tool. State your interpretation of the situation in 1–2 sentences — what is being analyzed and what the core question is — then ask:

• Question: "My read: [your 1–2 sentence interpretation]. How do you want to proceed?"
• Header: "Scope"
• Options:
  • Full analysis — Complete all steps, reasoning shown throughout
  • Key findings only — Bottom-line output, skip step-by-step detail
  • Channel recommendation only — Which medium and why, skip the full analysis
  • Reframe — The read is off; correct it and the analysis will follow the corrected framing

Proceed based on their selection. If the user reframes, incorporate the correction before running any analysis.

Output Format

Message assessment:

Dimension	Assessment
Goal	[What must receiver do/feel/understand]
Urgency	[Timeline]
Emotional weight	[None / Low / Medium / High — why]
Complexity	[One-way or requires dialogue]

Recommended medium: [Primary channel] Secondary medium (if needed): [Reinforcement channel + why]

Rationale:

[2-3 sentences on why this medium fits this message — and what would go wrong in the next-most-obvious alternative]

Notes

The most common error is defaulting to async written (Slack, email) for messages with high emotional weight, because it feels faster and less confrontational. The short-term comfort always costs more in trust and rework than the difficult conversation would have.
