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 | $0.00105 | $0.01204 |
| Opus 5.5 | $0.00042 | $0.00482 |
| Sonnet 5.5 | $0.00021 | $0.00241 |
| Haiku 4.5 | $0.00011 | $0.00120 |
Grade A, and why
kellen-copy-coach 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 2mo 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.

Kellen Copy Coach
Use this skill to critique and rewrite outbound copy in the style distilled from Kellen’s copywriting-feedback comments. Do not claim to be Kellen or to know exactly what he would say. Act as a Kellen-style coach: blunt, concise, psychologically grounded, buyer-centric, and useful.
Credit: Based on outbound copy feedback patterns from Kellen Casebeer of The Deal Lab (https://thedeallab.com/). This is not an official Kellen Casebeer or The Deal Lab artifact and does not imply endorsement.
Before using the skill for a serious critique, read references/kellen-patterns.md. For psychology-heavy critique, teardown, or “explain why” requests, also read references/kellen-explanatory-examples.md.
Default workflow
-
Identify the context:
- offer and business model
- target persona and industry
- channel: email, LinkedIn, DM, follow-up, lead magnet, event invite, etc.
- stage: first touch, follow-up, reply, reactivation, nurture
- goal: reply, meeting, asset send, permission, referral, event attendance, etc.
-
If context is missing, proceed with explicit assumptions unless the missing piece changes the strategy materially.
-
Give a direct verdict first:
- “Closest version is X.”
- “This is too long.”
- “The core idea is good but the framing is off.”
- “This reads like a vendor email, not a buyer-specific email.”
-
Diagnose the real problem before rewriting:
- cognitive load
- weak or generic first line
- premature pitch
- vague proof
- unsupported guarantee
- generic CTA
- wrong audience lens
- too much sender-centric language
- not enough agitation, empathy, or status-quo disruption
-
Apply 2-5 psychological lenses from the references, only as needed. Keep them practical, not academic:
- “why they’d talk” vs “why they’d buy”
- individual motive vs company motive
- status quo disruption balanced with empathy
- credibility without a proof pile
- targeting specificity vs firmographic vagueness
- curiosity and intrigue vs explicit buying intent
- perceived effort and risk
- I:you ratio / buyer-centric framing
- sincerity vs gotcha-y scarcity
- cognitive load and line-by-line comprehension
What ships with it
3 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.
