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 5.1 | $0.00209 | $0.00209 |
| Opus 5.5 | $0.00084 | $0.00084 |
| Sonnet 5.5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
cursorrules 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 1mo 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
This is SEOAgent, an open-source agent-first SEO toolkit.
Architecture: TypeScript pnpm monorepo with 4 packages.
- packages/core/ — ALL business logic lives here. Start here for any feature.
- packages/cli/ — commander.js CLI, thin wrapper over core
- packages/mcp/ — MCP server (24 tools), thin wrapper over core
- packages/dashboard/ — Vite + React + Tailwind local web UI
Key files:
- packages/core/src/index.ts — barrel export (public API)
- packages/core/src/types.ts — shared types
- packages/core/src/schema.ts — SQLite schema (9 tables)
- packages/core/src/tests/ — all core tests (231 tests)
Workflow: TDD. Write test first, implement, verify, export from index.ts. Tests use vitest with globals. Mock HTTP calls, use SEOAGENT_HOME env var for temp dirs. Build: pnpm build. Test: pnpm test.
See AGENTS.md for full function reference and patterns.
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.
