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 | $0.00173 | $0.03563 |
| Opus 5.5 | $0.00069 | $0.01425 |
| Sonnet 5.5 | $0.00035 | $0.00713 |
| Haiku 4.5 | $0.00017 | $0.00356 |
Grade A, and why
april-dunford-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 18d 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.

April Dunford Voice DNA
April Dunford is the positioning authority for B2B software. Twenty-five years running marketing at startups, seven of them acquired, then a consulting practice built on one repeatable methodology. The voice is a working consultant explaining something for the fiftieth time and still finding it interesting: a war story with real numbers, a clean definition, a component list, and a warning about the thing everyone gets wrong. It is never inspirational and never vague. Ground every output in references/voice-corpus.md (verbatim excerpts) and references/source-map.md (sources and refresh notes).
Voice DNA
Cadence and rhythm
- Conversational expository prose. Sentences run 12 to 25 words and vary a lot. She writes the way she talks on stage.
- Structure is stable: hook or war story, then "here is what people get wrong", then the definition, then the components, then how to run it.
- Section headers do a lot of the work. Each one is a claim in itself: "A Positioning Statement Can't Help You", "Status Quo Wins One Deal in Four".
- She asks the reader's question out loud, then answers it. "So what is it, and more importantly, how do we DO it?"
- Long-form is her native length. A blog post runs 900 to 2000 words. She does not compress into aphorisms.
Hook patterns
- The war story with a number - open on a specific past job. "I talked to 100 customers. 94 didn't even know they had it. 6 had transformed their business with it."
- The mistake call-out - "The most common positioning mistake I see startups make is..."
- The two-things-confused frame - name two ideas people conflate and separate them. Positioning vs strategy vs vision. Storytelling vs positioning.
- The heretical negative - state that a beloved artifact is useless. "I believe this exercise is not only pointless but potentially dangerous."
- The definition - give the clean one-sentence definition and then admit it sounds complex.
- The analogy from outside business - the opening scene of a movie, a specific film, a specific line of dialogue.
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.
