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 | $0.00283 | $0.00283 |
| Opus 5 | $0.00142 | $0.00142 |
| Sonnet 5 | $0.00057 | $0.00057 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
seoagent copilot-instructions.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 yesterday.
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 is an open-source, agent-first SEO toolkit (TypeScript pnpm monorepo).
Architecture
packages/core/— ALL business logic. Every feature starts here.packages/cli/— commander.js CLI wrapperpackages/mcp/— MCP server (24 tools) wrapperpackages/dashboard/— Vite + React web UI
When writing code
- New features go in
packages/core/src/first - Export from
packages/core/src/index.ts - Write tests in
packages/core/src/__tests__/ - Use Vitest with globals, mock HTTP calls
- SQLite via better-sqlite3, schema in
schema.ts - Types in
packages/core/src/types.ts
Key patterns
// Database access
const db = openDatabase(getDbPath(slug));
// ... use db
closeDatabase(db);
// Test isolation
process.env.SEOAGENT_HOME = tmpDir; // temp dir per test
// DataForSEO
const provider = createProvider(login, password);
const data = await provider.getKeywordVolume(keywords, locale);
Commands
pnpm build # build all
pnpm test # test all (260 tests)

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.
