voice-and-tone-design

When to use

• A team is producing copy across multiple surfaces and the same segment hears three different brands per quarter — name the voice so the surfaces converge.
• An audience-by-message matrix exists but each audience cell currently reads in a different tone, breaking the recognition signal across the segment.
• A new senior persona (CMO, founder, head-of-content) is asking for a voice-and-tone artefact that downstream writers can defend against.

Do NOT use to copy-edit individual assets (out of scope — that is a writer's job), draft the message stack (route to messaging-architecture), or pick channel-specific tactics like subject lines or ad creative formats (channel-agnostic skill).

Cognition cluster

• Mental model 13 — Occam's Razor. The simplest voice the segment can recognise across surfaces is the voice that survives contact with three writers under deadline. A five-attribute voice that no one remembers is brand-theatre. See docs/contracts/mental-models.md § 13.
• Mental model 15 — Signal vs. noise. Voice is the identification signal embedded in copy — without distinctiveness it is noise that competes with every peer's noise. Cut to the three attributes that only the segment hears as us. See mental-models.md § 15.
• Context-spine — product + customer-segment. Read product for the proofs the voice must carry (a voice that promises what the product cannot back is fiction); read customer-segment for the listening-register the audience already lives in. See context-spine.

Procedure

Step 0: Inherit the positioning frame and audience matrix

Identify the locked positioning anchors from positioning-strategy and the audience matrix from messaging-architecture. Voice without positioning is style; voice without an audience matrix is broadcast.

Step 1: Analyze the inherited voice

Read 6–10 recent assets across the largest surface set the team ships on. For each, note the register (formal · conversational · technical · playful) and one line that sounds like us (or like anyone). The output is an honest audit: what voice is currently shipping, not what the team intends to ship.

Step 2: Pick three voice attributes — and three only

Three attributes, each phrased as "<we are> X, not Y." The not Y is non-trivial: it names the credible adjacent voice the team is choosing against, not a strawman. Examples of the shape (not vocabulary):

• "Precise, not pedantic."
• "Confident, not boastful."
• "Concrete, not buzzword."

A four-attribute voice will collapse to three under deadline; pick the three now.

Step 3: Build the tone-by-context matrix

Tone modulates voice; voice is constant. For each context — error copy, marketing surface, sales follow-up, onboarding, executive summary, support reply — fill: what the audience is feeling · what the surface must do · which voice attribute leads · what tone amplifier or muter applies. The matrix is the tool writers actually reach for; the three attributes are the spine they hang the tone on.

Step 4: Validate against the recognition signal

Validate the voice on three checks:

1. Distinctiveness. Write the same sentence in three credible peer voices. Verify the team's voice is recognisable as distinct on first read — not on the second read after explaining the attributes.
2. Proof-coverage. Confirm the voice does not promise what the product (from the spine) cannot back. "Calm" without an uptime story is fiction. Verify each attribute against a proof.
3. Survives-deadline. Hand the artefacts to a writer who was not in the room. If the writer cannot reproduce the voice on a 30-minute draft, the voice is documented for the room, not the surface.

Step 5: Run the consistency review

Re-audit the assets from Step 1 against the locked attributes and tone matrix. Mark each line consistent · slipping · contradiction. Slipping is a writer-coaching problem; contradiction is a re-write. The review surfaces the load-bearing surfaces that need a re-pass, not a punitive list.

Step 6: Hand back

Hand the artefacts to writers across the surfaces, to editorial-calendar for cadence mapping, and to release-comms for launch-surface voice review.

Related Skills

WHEN to use this

• The unit of work is the voice (three attributes + tone-by-context matrix), not a single line of copy.
• Surfaces are diverging in tone and the segment cannot recognise the brand across them.
• A team needs an artefact that a writer on deadline can actually use.

WHEN NOT to use this

• Drafting the message stack (primary message + proofs) — route to messaging-architecture.
• Cadence and content-debt management — route to editorial-calendar.
• Copy-editing individual assets — out of scope; that is a writer's craft.
• Launch-wave announcement copy — route to release-comms.

When the agent should load this

• "Define our voice — three attributes, no more."
• "Mach uns einen Tone-by-Context matrix, der Schreibern auf Deadline hilft."
• "Why does our copy sound different on every surface?"
• "Run a voice consistency audit on last quarter's assets."
• "Pick the not-Y for each voice attribute."

Output

1. voice-attributes.md — three attributes in the "X, not Y" shape, with the proof-from-spine that backs each.
2. tone-by-context.md — one row per surface context, with audience feeling, surface job, lead attribute, and tone amplifier / muter.
3. consistency-review.md — audit of 6–10 recent assets, each line marked consistent · slipping · contradiction, with re-pass list ranked by surface load.

Gotcha

• A voice that pleases the room is usually below the noise floor — agreement is consensus, not distinctiveness.
• The not-Y is the work. "Confident, not boastful" is meaningful; "confident, not weak" is filler.
• Tone-by-context matrices over-amplify when the surface is high-stakes — a calm voice in error copy is the discipline, not the failure.

Do NOT

• Do NOT exceed three attributes — the fourth collapses on the first deadline.
• Do NOT prescribe channel-specific tactics or copywriting rules; tactics live with the channel owner.
• Do NOT promise voice attributes the product cannot back — "effortless" without an integration story is fiction the support queue will pay for.

Runnable example

Mid-market HR analytics tool, positioning locked (retention beats acquisition), audience matrix has HR director · CFO · IT-security:

• Voice attributes — "Precise, not pedantic." · "Confident, not boastful." · "Concrete, not buzzword."
• Tone-by-context — Error copy: audience scared, lead with precise, mute confident. Marketing surface: audience curious, lead with concrete, amplify confident. Onboarding: audience uncertain, lead with precise, amplify warmth modifier.
• Consistency review — 8 of 10 surveyed assets consistent; 1 slipping (CEO blog leans pedantic); 1 contradiction (homepage hero contradicts not buzzword with "synergistic"). Re-pass list: homepage hero (load-bearing surface, prioritised).
• Hand-off → writers across surfaces; release-comms voice-reviews the GA-wave announcement.
