Picked up without a restart. A project skill of the same name is shadowed by your personal one. For one repository only, swap ~/.claude/skills for .claude/skills. Claude Code docs ↗

Or take the whole library

This repo ships a .claude-plugin manifest, so Claude Code can install all 17 skills at once. Plugin skills are invoked as /<plugin>:<skill>, so they never collide with your own.

/plugin marketplace add zapier/gtm-cheat-codes
/plugin

The folder is the same in every client that implements the format — 46 of them — so if yours is not above, only the destination changes.

Campaign Postmortem

Use When

A marketing team needs to understand what happened in a campaign and turn the learning into better next-cycle decisions.

Workflow

  1. Confirm campaign name, date range, goals, channels, and audience.
  2. Gather approved source material: brief, launch plan, project notes, performance data, meeting notes, and team feedback.
  3. Build a timeline of major decisions, launch events, results, and follow-up actions.
  4. Compare goals to actual results with source references.
  5. Separate observations from interpretations.
  6. Identify what worked, what did not work, root causes, and open questions.
  7. Recommend what to repeat, change, or stop.
  8. Add an action register with owners, dates, and unresolved decisions when available.

Zapier MCP And SDK Role

  • Use Zapier MCP to gather approved campaign docs, conversations, dashboards, CRM context, meeting notes, and tracker state.
  • Use Zapier SDK for retro intake, scheduled reminders, reviewer routing, action logging, and follow-up tracking.
  • Keep metrics, claims, and broad sharing review-gated.

Output Format

  • Executive summary
  • Source list
  • Campaign timeline
  • Goal vs. actuals
  • What worked
  • What did not work
  • Root causes and caveats
  • Repeat / change / stop
  • Action register

Guardrails

  • Never invent metrics, attribution, causes, or owner commitments.
  • Label missing data and conflicting evidence.
  • Keep the retro focused on systems, decisions, and process, not personal blame.
  • Require human review before sharing broadly or updating source-of-truth records.

Files bundled with it

These load only when the skill asks for them, so they cost nothing until it runs.
