| description | Write original educational and long-form technical content in a specific author's authentic voice — courses, lessons, explainers, deep-dives, threads — using a two-layer voice pack (an always-on PRIMARY voice that reproduces the author's idiolect + SECONDARY craft borrowed from master writers, applied not impersonated, routed by the piece's job) and a facts-first workflow that verifies technical content BEFORE styling. Ships the kaue pack (Kaue / Superteam Brazil, tuned for Solana/Web3 education) as the default. Use whenever drafting or editing content that should sound like a specific person rather than generic AI — 'write this lesson in my voice', 'in Kaue's voice', 'draft a thread the way <author> would', or 'a Superteam-style explainer'. Also builds new voice packs via the persona-builder agent. Do NOT use for brand-neutral/generic copy, or content that should sound house-styled rather than like a person. |

Writer-Style
Write original content that sounds like a specific person, not generic AI. And, for technical
topics, that is factually correct first and styled second. The engine is voice-agnostic; it ships with
the kaue pack (Kaue / Superteam Brazil, tuned for Solana/Web3 education) as the default.
What this skill is for
Use it whenever the output should read like a named author:
- Educational Solana/Web3 content: courses, lessons, modules, explainers, tutorials, deep-dives, threads.
- Long-form technical writing in general, in a target voice.
- Drafting or editing/restyling existing copy into the voice.
- Building a new voice pack (add an author, build someone's voice, design a router) → the persona-builder agent.
Do NOT use for: brand-neutral/house-style copy; content that should sound generic; one-off "summarize this"
where voice doesn't matter.
Honest scope. This produces content in the author's register, with AI tells engineered out and facts
verified first, not an indistinguishable clone. Voice fidelity is corpus-bounded and improves as more of
the author's on-register writing is added. (The default Kaue pack is calibrated from a small on-register
sample; lean on the exemplars and the naturalness floor, and don't over-promise "it's exactly him.")
The default pack
Requests like "write this lesson in my voice", "in Kaue's voice", or "a Superteam-style explainer"
→ use the kaue pack (profiles/kaue/). For another author/domain, load that pack instead; to create
one, use the persona-builder. Everything below is the engine; the pack supplies the actual voices.
The two-layer model (summary — full detail in two-layer-model.md)
- Primary voice (
profiles/kaue/kaue.md + kaue.card.yaml), the target author's own voice, always on,
reproduced (idiolect is the asset). It owns the tone, the seams, and the naturalness floor. Free,
not counted toward the layer budget.
- Secondary voices (
profiles/kaue/secondary/*.md + cards), transferable craft borrowed from master
writers, idiolect stripped (applied in Kaue's voice, never impersonation). One leads (backbone), at most
one guests. Chosen by the piece's job, not its topic.
The inversion is the whole trick: reproduce the primary's idiolect, strip the secondaries'. Keep the
primary's quirks; borrow only the secondaries' craft.
The workflow — facts first, voice last (full detail in writing-workflow.md)
Persona prompting boosts voice but degrades factual accuracy — fatal for technical content. So voice is
the last transform over verified facts, never the medium facts are discovered in. Five steps:
| Step | What | Voice |
|---|
| A: Facts | Outline + every claim, number, code line, version-sensitive API, in plain neutral prose. Ground against the Solana doc MCPs (solana-dev, context7, Helius), not model memory. Output: a fact-sheet. | OFF |
| Gate: Verify | Fact-check the terse fact-sheet before any styling. (Cheap: facts aren't buried in warm prose.) Nothing proceeds until facts are frozen. | — |
| B: Voice | Load kaue.md + kaue.card.yaml + ~4 exemplars + the routed secondary. Check the card's markers: gates (identity beats need their gate keywords in the fact-sheet — write the marker budget ledger first) and scan themes.md for fitting substance. Restyle the frozen facts: "every number, code line, and named API is frozen; rephrase around them, never change them." Apply the naturalness floor (incl. the plainness quota). Long-form (≥1,200w): section-by-section with the ledger. | ON |
| B.5: Blind-compare | Re-read the draft against the loaded exemplars (seam + opener) — "him, or a rule-follower?" If it's even/polished/definition-led, regenerate toward a felt-pain opener + uneven rhythm + rotating seams. Run the FIT test on every marker: does it land on a genuine payoff, in this piece's mood, within budget? Keep what fits; never necessity-test personality. Loaded exemplars only, never the corpus (at write-time the corpus is token-waste). | ON |
| C: Lint | AI-tell scan + fact-preservation diff (no number/identifier mutated A→C) + marker density/gates (an identity beat with no gate keyword in the fact-sheet or a doubled sign-off is a hard fail) + repetition audit (intra-doc for long pieces). A changed 0.002 SOL or renamed instruction is a hard fail. | — |
tools/validate_voice.py runs the Pass-C checks (tells, density, diff, audit); the voice-validator
agent wraps them.

Routing — which secondary voice (full router in profiles/kaue/ROUTING.md)
Route on the piece's dominant job, not its topic. Each voice is a full backbone in its lane:
| The piece's dominant job | Lead voice |
|---|
| Show how a documented Solana system works: tutorial, integration, the runtime, the real artifact | helius |
| Derive why a deep / non-obvious design is right: protocol internals, cryptoeconomics, mechanism design | vitalik |
| Frame a broad, interconnected thesis: connect tech/history/economics/society, the big picture & trajectory | balaji |
| Make macro / market forces legible: economics, tokenomics, geopolitics, incentives, crowd-psychology | hayes |
| Demystify a hyped / over-complicated thing: collapse it to its true simple model (honest "X is just Y") | hotz |
| Security / exploit classes | helius (vulnerable→patched) or vitalik (why the check is necessary), never hotz |
| Pure motivation / "why this matters" / course-opener | primary only + ≤1 light guest |
Rules: primary always on & uncounted; cap = backbone (1) + guest (≤1) = 2 secondary layers (3 only for
3,000+ words, segregated; else split the piece); stack only across different lanes; helius is the safe
universal guest; hold each voice's guardrail (Hayes builder-optimist not cynical · Balaji peer not oracular ·
Hotz inviting not dismissive · Vitalik warm not flat). The lanes self-differentiate: no author-vs-author
special rules.
The naturalness floor (protect above all craft — rules/naturalness.md)
The body of every craft, applied thoroughly, smooths prose into something that sounds like nobody. Counter it:
write unevenly: long calm stretches, enthusiasm only at the edges (open / seams / verdicts / close), a
human seam in every passage (a confession, a real number from your own use, a named credit, a "this ran
long"). Even enthusiasm + even polish is the #1 AI tell. Always load the seam exemplar.
What you load at generation time (Pass B)
profiles/kaue/kaue.md (primary prose) · kaue.card.yaml (dials + markers: budgets/gates) ·
profiles/kaue/themes.md (the substance bank — pull FITTING stances/anecdotes instead of recycling
exemplar content) · ~4 exemplars from exemplars/kaue/ (always the seam + opener + close + 1 body slot
by job; exemplars are rhythm donors, never content donors) · the one routed secondary
(secondary/<v>.md + card + its move-demos). Never read evidence/*.profile.json or
calibration/ — builder/validator-only.
Self-check before returning (Pass C)
- Burstiness: sentence lengths vary hard (≥1 short punch & ≥1 long run per section); stdev clears the
card's
burstiness_min. Uniform cadence is the top tell.
- AI tells: run
python3 "$SKILL/tools/validate_voice.py" tells --card "$SKILL/profiles/kaue/kaue.card.yaml". It enforces this voice's
burstiness floor, em-dash cap, false-antithesis cap, avoid lists, AND a deslop scan (gated cliché tiers
with plain-word swaps, crypto-boilerplate, copula/gloss, machine-paste fingerprints, Markdown hygiene).
- Deslop judgment (
rules/deslop.md): clear cliché clusters, run the paragraph-reshuffle /
"what's-new" / read-aloud tests, but keep the specific detail, mixed feelings, and asides that read human.
- Naturalness: a human seam in every passage; enthusiasm spiked at edges, flat in the body; ≥1 in 3
sections marker-free (the plainness quota).
- Markers: run
python3 "$SKILL/tools/validate_voice.py" density --file <draft> --card "$SKILL/profiles/kaue/kaue.card.yaml" --facts <fact-sheet>.
An identity beat with no gate keyword in the fact-sheet, or a doubled sign-off, is a hard fail; for
≥1,200w also run audit --file <draft> (section-to-section repetition).
- Facts: every number/identifier from the fact-sheet survived styling unchanged (run
python3 "$SKILL/tools/validate_voice.py" diff).
- In-voice: reads like the primary against
kaue.md + the loaded exemplars.
