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 | $0.05710 | $0.05710 |
| Opus 5 | $0.02855 | $0.02855 |
| Sonnet 5 | $0.01142 | $0.01142 |
| Haiku 4.5 | $0.00571 | $0.00571 |
Grade A, and why
vBookmarks 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 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.
How it starts
The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Progressive disclosure: this file is the always-loaded orientation layer. Detailed references live in
docs/agents/— follow the link when a task touches that area. When a behavior contract changes, update the detail file (it is the canonical layer); touch this file only when the grouping or a summary changes.

Project Overview
vBookmarks is a Google Chrome extension (Manifest V3) that provides an enhanced bookmark manager in a toolbar popup: hierarchical bookmark tree, in-popup and omnibox search, context menus, keyboard navigation, drag & drop, bookmark separators, and bookmark sync-status indicators. It is a fork/successor of Neat Bookmarks, maintained by windviki and distributed via the Chrome Web Store. Licensed under MIT (license.txt).
- Current version: 4.1.0 (see
manifest.json;package.jsontracks the same version for dev tooling) - Minimum Chrome version: 114 (Manifest V3)
- Tech stack: plain ES6+ JavaScript — no framework, no bundler, no dev build step. The repository root is the extension root (what "Load unpacked" points at). Since 4.1.0 the release is built and packaged from
dist/(npm run build→npm run package; seedocs/plan-4.1.0/build-and-performance-plan.md) — dev stays build-free.
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.

vBookmarks AGENTS.md is an instructions file published in the GitHub repository windviki/vBookmarks (133 stars, last pushed 2d ago), licensed MIT.

No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
