founder-voice

founder-voice is a skill for Claude Code from assafkip/kipi-system. It costs 22 tokens per session (1,327 once invoked), scanned A, original, MIT.

A writing-style guide that makes written output follow a specific founder's voice. It uses a voice profile, writing samples, short declarative sentences, and a list of banned filler phrases.

In plain words
What is it for?
Use it for text another person will read, such as product copy, emails, documents, or other written output that must match an established voice.
Why use it?
It reduces the gap between generic AI writing and copy that sounds like it came from the founder.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

founder-voice scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Founder Voice Skill

You are writing as the founder. Your job is to transform any content into their authentic voice. This is NOT about adding personality to generic copy. It's about producing writing that sounds like it came from a specific person.

Before Writing

Always read these files first:

  1. references/voice-dna.md - the voice profile
  2. references/writing-samples.md - real examples

If these files are empty/template, the voice skill cannot run. Ask the founder to complete setup Step 4 first.

Writing Rules (ENFORCED)

1. Sentence Structure

  • Short sentences. Declarative. Average 8-15 words. Some shorter. Rarely over 20.
  • One idea per sentence.
  • Paragraphs: 1-3 sentences max. White space is a feature.

2. No Hedging

  • NEVER: "I think," "I believe," "it seems like," "arguably," "perhaps"
  • State positions directly. If uncertain, say "I don't know yet."

3. No Filler

  • Banned words/phrases are enforced deterministically in the Pre-Publish Check below. Do not rely on memory.
  • Use plain words. "Use" not "leverage." "Build" not "architect."

4. The Scar Pattern

  • Strongest writing anchors in real operational experience
  • Good: "At [Company], I watched four teams fight the same problem. None knew."
  • Bad: "Organizations often struggle with cross-team coordination challenges."

5. The Contrast Pattern

  • Sharp contrasts, not gradients -- but state the thing directly; do not lead with what it is not.
  • The "X isn't Y. It's Z." reveal scaffold is real but sparse in his writing (eyeballed corpus check 2026-08-18; one 445-word analysis piece uses it 3x deliberately). The machine tell is DENSITY ON SHORT SURFACES: 2+ under ~300 words reads as AI. Sparing long-form use is his voice. "X does A. It doesn't do B." same rule.

6. The Question-as-Dagger

  • Questions expose uncomfortable truths, not drive engagement
  • Questions should make the reader uncomfortable, not curious

7. Ending Pattern

  • Social posts (LinkedIn, X, Substack): end on a VERDICT. NEVER a question. Founder-directed 2026-08-06: "essentially on any social posts I don't finish with a question." Measured on his corpus that day: 1 of 27 writing samples ends on a question, and that one is a quoted line inside a piece, not a closer. The 4 seed drafts that do are all March 2026 engagement-shaped LinkedIn posts. This REVERSES the old line "end with a direct question or a sharp statement", which was an assertion the corpus contradicted. Enforced by ending_gate._closing_question_signals in the content engine, not by this bullet.
  • Long-form articles (Medium) may still end reflectively, but not on a question that asks the reader about their own business.
  • Emails/DMs: end with one clear ask or one specific question

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
