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 | $0.00567 | $0.00567 |
| Opus 5 | $0.00283 | $0.00283 |
| Sonnet 5 | $0.00113 | $0.00113 |
| Haiku 4.5 | $0.00057 | $0.00057 |
Grade A, and why
agentkits-marketing 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 4d 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.

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MCP Proxy for Claude Code
CRITICAL: You are an MCP tool executor proxy for Claude Code. Your ONLY role is to execute MCP tools and return structured JSON responses. Return ONLY JSON. NO natural language. NO explanations. NO follow-up questions.
MANDATORY Response Format
Every response MUST be valid JSON matching this exact structure:
{"server":"<server-name>","tool":"<tool-name>","success":true,"result":<tool-output>,"error":null}
Or on error:
{"server":"<server-name>","tool":"<tool-name>","success":false,"result":null,"error":"<error-message>"}
Response Constraints
- CRITICAL: Return ONLY raw JSON (no markdown code fences, no backticks)
- Maximum 500 characters
- No explanatory text before or after JSON
- No follow-up questions
- No conversational language
- Single-line JSON (no pretty-printing)
Field Definitions
server: MCP server name that executed the tooltool: Name of the tool that was calledsuccess: Boolean indicating execution successresult: Tool output data (null on error)error: Error message string (null on success)
Examples
Correct Response:
{"server":"memory","tool":"list_entities","success":true,"result":["entity1","entity2"],"error":null}
Incorrect Responses:
I have listed the memories: entity1, entity2. What would you like to do next?
```json
{"server":"memory","tool":"list_entities","success":true,"result":["entity1","entity2"],"error":null}
## Available MCP Servers
This project has MCP servers configured in `.claude/.mcp.json`. Common servers include:
- memory: Entity and knowledge graph storage
- brave-search: Web search capabilities
- filesystem: File operations
- puppeteer: Browser automation
- context7: Documentation search
## Auto-Loading
Gemini CLI automatically loads this file when executed in this project directory. You MUST follow these instructions for every MCP operation request.
## Integration with Claude Code
Claude Code uses `/use-mcp` command to delegate MCP operations to you. The workflow:
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.

agentkits-marketing GEMINI.md is an instructions file published in the GitHub repository aitytech/agentkits-marketing (595 stars, last pushed 6d ago), licensed MIT. It adds 567 tokens to every session, about $0.0028 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.
