+# No Agent Marketing Policy (Strict)
+
+This document defines the strict policy for prohibiting agent marketing material in project artifacts.
+
+## Core Principle
+
+**Commits, pull requests, issues, and comments must not contain promotional material for AI tools.** We are not paid for this advertising and it does not belong in our project history.
+
+## The Rule
+
+| Artifact | Prohibited content |
+|----------|-------------------|
+| Commit messages | Co-Authored-By trailers referencing AI agents; marketing footers |
+| PR titles | "Generated with...", "Built with...", or similar AI tool attributions |
+| PR descriptions | Marketing footers, AI tool attribution links, co-author trailers |
+| Issues | AI tool attribution or promotional footers |
+| Comments | AI tool attribution or promotional footers |
+
+### Patterns that violate this policy
+
+- `Co-Authored-By:` trailers referencing AI agents (Claude, Copilot, ChatGPT, Gemini, Cursor, etc.)
+- `Co-Authored-By:` trailers using agent noreply addresses (e.g. `noreply@anthropic.com`, `noreply@github.com`)
+- Footers like "Generated with [Tool Name]", "Built with [Tool Name]", "Created using [Tool Name]"
+- Markdown-link attributions like `Generated with [Claude Code](https://...)`
+
+## Examples
+
+### Compliant: Clean commit message
+
+```
+feat(worker): add request batching support
+```
+
+### Compliant: PR description without marketing
+
+```markdown
+## Motivation
+
+Workers currently process requests one at a time.
+
+## Approach
+
+Add a batching queue that groups requests by type.
+```
+
+### Non-Compliant: Co-author trailer for AI agent
+
+```
+feat(worker): add request batching support
+
+Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
+```
+
+### Non-Compliant: Marketing footer in PR body
+
+```markdown
+## Motivation
+
+Workers currently process requests one at a time.
+
+## Approach
+
+Add a batching queue that groups requests by type.
+
+🤖 Generated with [Claude Code](https://claude.ai/claude-code)
+```
+
+### Non-Compliant: Attribution in PR title
+
+```
+feat(worker): add request batching support (built with Copilot)
+```
+
+## Verification Checklist
+
+Before marking a review complete, verify:
+
+- [ ] No commit messages contain `Co-Authored-By:` referencing AI agents
+- [ ] PR title does not contain AI tool attributions
+- [ ] PR description does not contain marketing footers or attribution links
+- [ ] No "Generated with", "Built with", or "Created using" followed by an AI tool name
+
+## Common Mistakes
+
+| Mistake | Fix |
+|---------|-----|
+| Leaving default Co-Authored-By trailer from AI tool | Remove the trailer from the commit message |
+| Forgetting to remove "Generated with..." footer from PR template | Delete the footer line |
+| Including AI tool attribution in a markdown link | Remove the entire attribution line |

 - Use `*[Symbol.iterator]` pattern for reusable stream operations (see Stateless Streams policy)
 - Avoid `sleep()` for test synchronization (see No-Sleep Test Sync policy)
 
+## Commit and PR conventions
+
+Use [gitmoji](https://gitmoji.dev) for commit and pull request subjects. For
+changes to files that direct the behavior of AI such as AGENTS.md or llms.txt
+use a robot emoji instead of the standard gitmoji for documentation

+Do not include any agent marketing material (e.g. "Generated with...",
