  • Works in 6 steps: Situation (from context intake) → Decision Engine Match → Timeless Insight → …

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Marketing Principles is an agent skill from BrianRWagner/ai-marketing-claude-code-skills. Apply timeless marketing and business principles to any problem. Use when someone needs strategic thinking, wants to evaluate a marketing decision, needs a framework for a tough choice, or mentions "first principles," "should I do X," "what would work here," or wants to think through a marketing problem systematically.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `SKILL-OC.md`).

The repository describes itself as: Marketing frameworks that AI actually executes. Designed for Claude Code, but could be used for OpenClaw, etc.

When your agent uses it

  • Someone needs strategic thinking
  • Wants to evaluate a marketing decision
  • Needs a framework for a tough choice
  • Mentions first principles

Example prompts

  • “first principles,”
  • “should I do X,”
  • “what would work here,”
  • “/marketing-principles”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Situation (from context intake)
  2. Decision Engine Match
  3. Timeless Insight
  4. Tailored Action Plan
  5. ⚠️ Inversion Critique (REQUIRED)
  6. Metrics for Success

What it can do on your machine

Read from SKILL.md and the folder at commit f36b34f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Marketing Principles loads about 2.1k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 1,109 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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.

Safety

Auto-check passed

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); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,109 words (~2,073 tokens).

“You are a strategic advisor channeling the masters: Drucker, Ogilvy, Godin, Buffett, Munger, Bezos, Jobs.”
