Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

create-skill 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 4d 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 — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/create-skill — Skill Creator

Meta-skill for extending the mktg marketing playbook. You create new skills that follow the drop-in contract so they work immediately with /cmo, mktg doctor, and the full skill ecosystem.

For brand memory protocol, see /cmo rules/brand-memory.md.

On Activation

  1. Read the skill contract: workflows/create-new-skill.md
  2. Read the template: templates/marketing-skill.md
  3. Read skills-manifest.json in the project root to understand existing skills and avoid overlap.
  4. Ask: What marketing capability should this skill add?

Phase 0: Validate the Need

Gate check. Before creating a new skill, verify it doesn't already exist:

Signal Action
Capability covered by existing skill Skip. Point to the existing skill.
Slight variation of existing skill Skip. Suggest extending the existing skill instead.
Genuinely new marketing capability Proceed.
Orchestrator chaining existing skills Proceed. Mark as orchestrator layer.

Check skills-manifest.json for the full list. Common near-misses:

  • "social media copy" → /content-atomizer already handles this
  • "brand guidelines" → /brand-voice covers this
  • "SEO strategy" → /keyword-research + /seo-audit cover this

Phase 1: Gather Requirements

Ask these questions (one at a time, stop when clear):

  1. Name — What should the skill be called? (kebab-case, e.g., webinar-funnel)
  2. Trigger phrases — What would someone say to invoke this? (5-8 natural phrases)
  3. Category — Where does it fit? (foundation / strategy / copy-content / distribution / creative / seo / conversion / growth / knowledge)
  4. Layer — What layer? (foundation / strategy / execution / orchestrator)
  5. Tier — How essential? (must-have / nice-to-have / experimental)
  6. Brand reads — Which brand/ files does it need? (voice-profile.md, audience.md, etc.)
  7. Brand writes — Which brand/ files does it update?
  8. Dependencies — Which skills should run first? (e.g., brand-voice, audience-research)
  9. Core workflow — What are the main phases? (3-5 phases typical)

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.

Changes

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.
