Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00838 | $0.00838 |
| Opus 5 | $0.00419 | $0.00419 |
| Sonnet 5 | $0.00168 | $0.00168 |
| Haiku 4.5 | $0.00084 | $0.00084 |
Grade A, and why
markifact-mcp GEMINI.md 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 2d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Markifact
You have access to the Markifact MCP server at https://api.markifact.com/mcp. It exposes 8 meta-tools that let you run 1000+ marketing operations across Google Ads, Meta Ads, GA4, DV360, Shopify, HubSpot, TikTok, LinkedIn, Pinterest, Snapchat, Microsoft, Amazon, Reddit Ads, Klaviyo, Slack, and more.
The 8 tools
find_operations(query)— search the operation registry. Always call this first. Each result includes arequires_approvalflag.get_operation_inputs(operation_id)— get required + optional input fields.run_operation(operation_id, inputs)— execute an op withrequires_approval: false. No confirmation needed.run_write_operation(operation_id, inputs)— execute an op withrequires_approval: true. Always confirm with the user first.list_connections()— list authenticated platform logins. Connections auto-resolve to the user's default — only call this when the user has multiple logins on a platform or names a specific one.get_file_url(file_id)— signed URL for a Markifact-stored file. Always use this when sharing a file with the user; embed via Markdown.read_file(file_id)— read a file the user uploaded or an op produced.upload_media(...)— upload an image or video as a creative asset (no other file types).
Discover → Inspect → Run
Never invent operation IDs. Never guess input field names. Always:
find_operations("plain english intent")— read therequires_approvalflag on each result.get_operation_inputs(chosen_id).- Dispatch by the flag:
requires_approval: false→run_operation(...);requires_approval: true→run_write_operation(...)after the four-step safety protocol.
Connection vs account
- A connection is an OAuth login (e.g.
[email protected]). One connection can hold many ad accounts. Auto-resolved — do nothing about it by default. - An account is a specific ad account (Google Ads CID, Meta ad account). Always resolve via the platform's
*_select_accountsop (substring match on the account name).
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.
