Messaging architecture

messaging-architecture

When to use

• Positioning is locked (four anchors + assumption ledger) and the next artefact — launch deck, homepage, sales narrative — needs a load-bearing message stack instead of one-off copy.
• A team is shipping copy faster than it is shipping shared meaning; lines diverge across surfaces and the segment cannot recognise itself.
• An audience-by-message matrix is missing and the same primary message is being shouted at three audiences who hear three different things.

Do NOT use to write the copy itself (downstream of this skill), peer-vs-peer comparison (route to competitive-positioning), or launch sequencing (route to gtm-launch).

Cognition cluster

• Mental model 15 — Signal vs. noise. Every message lands inside an inbox that is already full. The primary message must clear the segment's noise floor, not just be true. Estimate the noise before drafting; without it, every line looks distinctive in the doc and forgettable in market. See docs/contracts/mental-models.md § 15.
• Mental model 30 — Inversion. Ask "what is the strongest message a credible alternative would land against us?" The answer exposes the proofs the message stack must carry, not the words. See mental-models.md § 30.
• Context-spine — product + customer-segment. Read the product slot for the proofs the team can actually back; read the customer-segment slot for the buyer's listening posture. Architecture that exceeds the proofs available is fiction. See context-spine.

Procedure

Step 0: Inherit the positioning frame

Open the positioning.md artefact (positioning-strategy Step 1 output). If the four anchors are missing or contested, stop and route back. Messaging architecture without a locked positioning frame is decoration — it will be rewritten the next quarter.

Step 1: Identify the primary message

Identify the one sentence — the load-bearing claim that, if the segment remembered nothing else, would still trigger the right switch event. Structure:

"For <segment>, <category> that <load-bearing benefit>, instead of <alternative>."

The benefit must be the switch-event benefit — what changes the day they buy — not a feature list and not a brand attribute.

Step 2: Stack the supporting proofs

Three proofs, ranked. Each proof is a sentence the team can defend with evidence (data, demo, reference, contract clause). Proofs that need adjective amplification ("truly seamless", "radically simple") are not proofs — they are the gap a proof would fill.

Rank the proofs by closing weight: how much each moves the buyer's decision from no to yes. The order is the order of appearance in every downstream surface.

Step 3: Build the audience-by-message matrix

Audiences are not segments — they are roles inside the segment (economic buyer, champion, end-user, finance, security). For each audience, fill: what they fear · what they hope · what proof clears each. The matrix forces the team to confront the surfaces where the primary message lands wrong on a role even when right on the segment.

Step 4: Validate against the noise floor and the inversion test

Validate the stack on three checks:

1. Noise floor. For the primary message, name three lines a credible peer says today. If the primary message would not be distinguishable when read alongside them, it is below the noise floor — sharpen or drop.
2. Inversion. Write the strongest counter-message a credible alternative would land against us. Confirm at least one supporting proof neutralises it; if none does, the stack is missing a proof.
3. Proof-coverage. For every fear / hope cell in the matrix, verify a proof exists. Cells without a proof are explicit gaps, not silent omissions.

Step 5: Hand back

Hand the three artefacts (see ## Output) to gtm-launch for launch-wave sequencing, editorial-calendar for cadence mapping, or fundraising-narrative for capital-raising framing. Do not write the copy here — copy production is a downstream artefact.

Related Skills

WHEN to use this

• The unit of work is the message stack (primary + proofs + matrix), not a copy block.
• Positioning is locked and downstream surfaces need a shared anchor.
• Cross-audience messaging has scattered and the team cannot name a primary.

WHEN NOT to use this

• Locking the four-anchor positioning frame — route to positioning-strategy.
• Peer-vs-peer ours-vs-theirs verdict table — route to competitive-positioning.
• Launch-wave audience sequencing — route to gtm-launch.
• Voice attribute selection or tone-by-context matrix — route to voice-and-tone-design.

When the agent should load this

• "Lock the message stack before we draft the launch deck."
• "Wir brauchen eine primary message, keine Tagline."
• "Build the audience-by-message matrix for the security buyer."
• "Are our three proofs distinguishable from <incumbent>'s lines?"
• "Inversion-check our messaging against the alternative."
• "Our message has scattered across landing pages — re-anchor it."

Output

1. primary-message.md — one sentence in the segment / category / benefit / alternative shape, plus the load-bearing word and why it is load-bearing.
2. supporting-proofs.md — three proofs ranked by closing weight, each with the evidence the team can defend it with.
3. audience-matrix.md — one row per audience: fear · hope · proof-that-clears-each · primary-message variant if reframing is needed.

Gotcha

• A primary message everyone in the room agrees with on first read is usually below the noise floor — agreement is consensus, not distinctiveness.
• Proofs that need adjectives are signals of a missing proof; replace the adjective with the evidence or remove the line.
• The audience matrix tempts the team to multiply primary messages. Resist: the segment receives one primary; the matrix shapes emphasis, not substitution.

Do NOT

• Do NOT write copy in this skill — copy lives downstream.
• Do NOT inflate the stack beyond three proofs; a stack of seven is a wishlist, not architecture.
• Do NOT skip the noise-floor check; an internally distinctive message is not the same as a market-distinctive one.

Runnable example

Mid-market HR analytics tool, positioning locked (segment: HR leaders at 200–2000-person growing companies; alternative: spreadsheet + HRIS report; PoV: retention beats acquisition):

• Primary message: "For HR leaders at growing 200–2000-person companies, the workforce-analytics layer that turns the board-quarter retention conversation into a one-click roll-up, instead of a spreadsheet rebuild every quarter."
• Proofs ranked by closing weight: (1) cohort attrition by tenure band in < 5 clicks (demo); (2) plugs into the existing HRIS, not a replacement (architecture diagram); (3) board-quarter rebuild collapses from ~ 8 hours to ~ 1 hour (reference customer, contractually quoted).
• Audience matrix — Champion (HR director): fear = another tool to maintain; hope = looks competent to CEO; proof = HRIS plug-in. Economic buyer (CFO / COO): fear = soft ROI; hope = retention saving; proof = reference quote with hours saved.
• Hand-off → gtm-launch sequences launch waves around the retention-conversation moment in board-quarter cadence.
