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 | $0.03239 | $0.03239 |
| Opus 5.5 | $0.01296 | $0.01296 |
| Sonnet 5.5 | $0.00648 | $0.00648 |
| Haiku 4.5 | $0.00324 | $0.00324 |
Grade A, and why
zingit 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 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.
How it starts
The opening of the file, as written. The whole thing — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ZingIt - AI Agent Guide
Project Overview
ZingIt is a browser-based marker tool that allows users to click on webpage elements and add notes/instructions. These markers are then sent to an AI agent (Claude Code, GitHub Copilot CLI, or OpenAI Codex) which can automatically implement the requested changes.
Use case: Point-and-click UI feedback that gets automatically implemented by AI.
Key Features:
- Visual element selection with marking
- Multi-agent support (Claude, Copilot, Codex)
- Automatic screenshot capture
- Change history tracking
- Remote/local URL detection with warnings
- Keyboard shortcuts for fast 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.
- 1mo ago First seen · 328 lines · 3,239 tokens per session scan A bdcc62acab9e
zingit AGENTS.md is an instructions file published in the GitHub repository DanWahlin/zingit (7 stars, last pushed 2mo ago), licensed MIT. It adds 3,239 tokens to every session, about $0.0130 per session on Opus 5.5. 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 2026-08-31.
