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 | $0.00290 | $0.00290 |
| Opus 5 | $0.00145 | $0.00145 |
| Sonnet 5 | $0.00058 | $0.00058 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
cursor-rules AGENTS.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 today.
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
Agent instructions
Project conventions for AI coding agents live in .cursor/rules/*.mdc and .cursor/skills/*/SKILL.md. Cursor loads them automatically. If you are a different agent (Claude Code, Codex, Copilot, etc.), read these before making changes:
If .cursor/rules/template-repo.mdc exists, read it first — you are in the template repository, not a consumer app. That file is not part of the copy set.
.cursor/rules/global-rules.mdc— how to behave: ask vs. act, scope discipline, security awareness.cursor/rules/product.mdc— what this is and who it's for.cursor/rules/tech.mdc— stack, conventions, database, git rules.cursor/rules/security.mdc— non-negotiable security rules.cursor/rules/design.mdc— UI standards (only relevant when touching UI).cursor/rules/structure.mdc— where files go.cursor/rules/documentation.mdc— doc location and what to keep current.cursor/rules/models.mdc— Cursor-specific model guidance; safe to skip outside Cursor
Workflows: .cursor/skills/update-docs/SKILL.md (run after shipping a feature).
Don't duplicate rule content here. This file is intentionally a pointer.
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.

cursor-rules AGENTS.md is an instructions file published in the GitHub repository BOXELS/cursor-rules (6 stars, last pushed yesterday), licensed MIT. It adds 290 tokens to every session, about $0.0014 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 2026-09-15.
