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 | $0.00348 | $0.00348 |
| Opus 5 | $0.00174 | $0.00174 |
| Sonnet 5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
seoagent 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.
What it actually says
SEOAgent — Gemini Agent Instructions
See AGENTS.md for full details. This file covers Gemini-specific setup.
Overview
SEOAgent is a TypeScript monorepo (pnpm workspaces) with 4 packages:
@seoagent/core— all logic (260 tests)seoagent— CLI (commander.js)seoagent-mcp— MCP server (24 tools)@seoagent/dashboard— Vite + React web UI
Commands
pnpm install # install
pnpm build # build all
pnpm test # test all
Key Principle
Every feature is a function in packages/core/src/ first. CLI, MCP, and dashboard are thin wrappers. If you're adding functionality, start in core.
File Layout
- Business logic:
packages/core/src/*.tsand subdirectories (audit/,gsc/,strategy/,providers/) - Types:
packages/core/src/types.ts - Public API:
packages/core/src/index.ts(barrel) - Tests:
packages/core/src/__tests__/ - CLI:
packages/cli/src/commands/ - MCP:
packages/mcp/src/tools/ - Dashboard API:
packages/dashboard/src/server/routes.ts - Dashboard UI:
packages/dashboard/src/app/pages/
Testing
Vitest with globals. Mock external APIs. Use temp dirs with SEOAGENT_HOME env var.

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.
