Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00702 |
| Opus 5 | $0.00000 | $0.00351 |
| Sonnet 5 | $0.00000 | $0.00140 |
| Haiku 4.5 | $0.00000 | $0.00070 |
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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: founder-voice description: "Founder voice enforcement for all written output. Apply to any text another person will read."
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 is about producing writing that sounds like it came from a specific person.
Before Writing
Always read these files first:
references/voice-dna.md- the voice profilereferences/writing-samples.md- real examples
If these files are template stubs (the originals shipped with the kit), the voice skill cannot run. Ask the founder to complete setup before drafting anything.
Writing Rules (ENFORCED)
1. Sentence Structure
- Short sentences. Declarative. Average 8 to 15 words. Some shorter. Rarely over 20.
- One idea per sentence.
- Paragraphs: 1 to 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 and phrases are enforced deterministically by the voice-lint hook. 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:
- "X isn't Y. It's Z." or "X does A. It doesn't do B."
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: end with a direct question or sharp statement. Never "Thoughts?" or "Agree?"
- Articles: end with a reflective question that reframes the whole piece.
- Emails and DMs: end with one clear ask or one specific question.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

founder-voice is a skill published in the GitHub repository assafkip/founder-voice-kit (2 stars, last pushed 14d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 702 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

humanizer
Rewrite AI-sounding text so it reads like the writer without changing what it says. Use when editing or reviewing prose for AI tells: not-X-but-Y contrasts, one-line closers, staged openers, forced triads, dashes everywhere, inflated claims, sales language, stock AI words, bold labels, or filler. Based on Wikipedia's…
avoid-ai-writing
Audit and rewrite content to remove AI writing patterns ("AI-isms"). Use this skill when asked to "remove AI-isms," "clean up AI writing," "edit writing for AI patterns," "audit writing for AI tells," or "make this sound less like AI." Supports a detect-only mode, an edit-in-place mode for files, an optional voice…
ai-writing-detector
Use when the user asks to detect, scan, audit, score, or flag AI-writing patterns without rewriting the text, including requests for a deterministic local detector result when the host can execute Node.
preservation-verifier
Use when the user provides an original and rewritten version, asks whether a rewrite preserved protected content, or wants a deterministic check for code, frontmatter, quotes, tables, links, paths, numbers, headings, and residual AI-pattern regressions.
avoid-ai-writing-router
Use when a request combines AI-writing audit, rewrite, file editing, voice preservation, false-positive interpretation, verification, or when the user invokes Avoid AI Writing without naming a mode.
false-positive-reviewer
Use when a user asks what AI-writing flags mean, whether detector output proves AI authorship, or wants a careful interpretation of possible false positives, especially for academic, hiring, publication, disciplinary, or other consequential decisions.
