cmo-advisorMarketing leadership advisor on brand strategy, demand generation, and marketing operations.
Cmo Advisor is an agent skill from borghei/Claude-Skills. Marketing leadership advisor on brand strategy, demand generation, and marketing operations. Use when building a marketing strategy, planning demand-gen campaigns, designing lead scoring models, or aligning marketing with revenue.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `scripts/brand_health_tracker.py`, `scripts/channel_mix_optimizer.py` and `scripts/marketing_roi_calculator.py`).
It sits in Marketing & SEO, covering Lead generation, Go-to-market strategy and Brand strategy and identity. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4a698e8. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Cmo Advisor loads about 2.6k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 915 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

|---|---|---|
| Blended CAC increasing quarter over quarter | Channel saturation or scaling into less efficient channels | Run channel_mix_optimizer.py; cut lowest-ROI channels; increase investment in highest-ROI |
| Marketing sourced pipeline below 40% of total | Over-reliance on outbound/sales-sourced; marketing underinvesting in demand gen | Shift budget: target 40-60% marketing-sourced pipeline; invest in content + paid channels |
| Brand awareness below 30% in target market | Insufficient top-of-funnel investment; brand treated as afterthought | Allocate 15-20% of budget to brand; measure aided awareness quarterly |
| MQL-to-SQL conversion below 20% | Lead scoring threshold too low or ICP mismatch | Recalibrate MQL threshold; audit scoring model; tighten ICP definition |
| Marketing Efficiency Ratio (MER) below 1.0x | Spending more on marketing than generating in new ARR | Audit channel mix; pause negative-ROI channels; focus on proven converters |
| No brand tracking in place | Half of B2B SaaS companies don't track brand at all | Implement quarterly brand health survey using brand_health_tracker.py framework |
In Scope: Marketing ROI calculation, channel performance analysis, brand health tracking, lead scoring, campaign planning, budget allocation optimization, multi-touch attribution, competitive share of voice.
Out of Scope: Content creation, creative design, social media posting, email campaign execution, event logistics, PR execution, website development.
Limitations: Marketing ROI calculator uses provided attribution data -- accuracy depends on attribution model quality. Brand health tracker relies on survey data which may have sampling bias. Channel mix optimizer uses historical performance with diminishing returns modeling -- future performance may differ due to market changes. MER calculation requires accurate new ARR attribution which many companies struggle to measure precisely.

Run `npx skills add borghei/Claude-Skills --skill cmo-advisor -a claude-code`. Or copy the skill folder (c-level-advisor/cmo-advisor in borghei/Claude-Skills) into .claude/skills/cmo-advisor in your project. Claude Code loads it when a task matches its description.
Run `npx skills add borghei/Claude-Skills --skill cmo-advisor -a codex`. Or copy the skill folder (c-level-advisor/cmo-advisor in borghei/Claude-Skills) into .agents/skills/cmo-advisor in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add borghei/Claude-Skills --skill cmo-advisor -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cmo-advisor, .gemini/skills/cmo-advisor, .github/skills/cmo-advisor and .opencode/skills/cmo-advisor in your project.
Going by SKILL.md and its folder, Cmo Advisor needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Cmo Advisor is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.6k tokens (SKILL.md is roughly 10k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Cmo Advisor: Startup Design (ferdinandobons/startup-skill, 1.2k stars), B2b Brand Marketing (arnabbagxd/Brand-building-skills, 720 stars), Positioning Basics (BrianRWagner/ai-marketing-claude-code-skills, 440 stars) and 22 Personal Brand Context Global (minhnv0807/ai-business-skills, 608 stars).
