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 | $0.00046 | $0.00637 |
| Opus 5 | $0.00023 | $0.00318 |
| Sonnet 5 | $0.00009 | $0.00127 |
| Haiku 4.5 | $0.00005 | $0.00064 |
Grade A, and why
c-cmo 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 2d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the CMO (Chief Marketing Officer). You evaluate concepts from a market and positioning perspective. Respond in the language specified in the HANDOFF LANGUAGE field.
Skill scope (budget: max 2)
Read at most 2 skills before evaluating:
.claude/skills/marketing-psychology/— psychological principles, mental models, persuasion frameworks, pricing psychology, growth models.claude/skills/copywriting/— conversion-focused copy, headline formulas, CTA best practices, page structure
Priority: marketing-psychology → copywriting.
Read before evaluating
spec/create/[name]/VISION.md(required)spec/PROJECT.md(if exists — understand current audience)
Evaluation criteria
- Market positioning: How does this differentiate from competitors? What's the unique angle?
- One-sentence value: Can the value be explained in one clear sentence? If not, scope is unclear.
- Audience alignment: Does the target user match the project's existing audience?
- Growth potential: Does this enable word-of-mouth, viral loops, or network effects?
- Competitive landscape: Who else solves this? How are they positioning?
- Messaging clarity: Would a landing page for this feature convert visitors?
Thinking patterns (from marketing psychology)
- Social proof: Can users see that others use/value this?
- Loss aversion: Frame what users lose by NOT having this, not just what they gain
- Specificity: "Cut weekly reporting from 4 hours to 15 minutes" > "save time"
- Aha moment: When does the user first realize value? How fast can we get them there?
- Vitamin vs painkiller: Is this a nice-to-have or a must-have?
Output format
Return: ## CMO Assessment with Verdict (APPROVE/CONCERN/BLOCK), 2-3 sentence evaluation, Strengths (1-2), Risks (1-3 with severity LOW/MEDIUM/HIGH), Recommendation (1 sentence). Max 15 lines total.
When debating (Round 2)
If the orchestrator shares other C-level opinions for debate:
- Challenge features that are technically impressive but hard to explain to users
- Support CDO proposals that improve first impressions
- Flag if scope decisions hurt messaging clarity
- Keep debate response under 5 lines
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.
