mb-ads

A workflow for creating and reviewing advertising copy and creative plans, including launch checks, variations, video scripts, and compliance review.

In plain words
What is it for?
Use it to draft ad copy or images, create creative variations, write video or long-form ad scripts, review compliance, plan launches, check websites, or review ad-account performance.
Why use it?
It organizes ad work around the business repository’s current readiness, measurement, offer, and conversion-path facts before creative or launch decisions.

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

mb-ads 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 yesterday.

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.

The opening of the file, as written. The whole thing — 500 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ads Skill

Create ads, generate creative variations, review for compliance, and check ad account performance.

CLI facts first: Find the business repo, run mb status --json --peek, then use status readiness, drift, integrations, measurement, and ranked actions before scoring creative depth or asking setup/provider questions.

Shared Workflow Contract

Engine source workflow: workflows/mb-ads/workflow.md. This skill is the Claude Code shell over that source. Preserve the shared source's fact-first routing, launch-plan boundaries, provider gates, and read/write rules.

Shared source required mb commands:

  • mb status --json --peek
  • mb start --json
  • mb doctor repair --plan
  • mb connect doctor --json
  • mb connect plan
  • mb launch check "$SITE_REPO" --business-repo "$BUSINESS_REPO" --json
  • mb site check "$SITE_REPO" --business-repo "$BUSINESS_REPO" --json
  • mb validate --cross-refs --json
  • mb checkpoint --plan --json

Shared source required JSON fact paths:

  • money_path
  • money_path.objects.proof.quality
  • money_path.objects.cta_path
  • money_path.objects.channel_strategy
  • money_path.objects.active_push
  • validation.file_contracts

Shared source gates: updates_repairs_migrations, file_writes, checkpoint, provider_mutation, publishing_or_spend, customer_contact, private_data, destructive_operations, structured_collection, public_issue_or_proposal, account_change, upload_assets, budget_change, campaign_publish, conversion_upload, gtm_publish.

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.

mb-ads is a skill published in the GitHub repository noontide-co/mainbranch (37 stars, last pushed 17d ago), licensed MIT. It adds 136 tokens to every session and 5,897 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
