Token cost

What it costs to keep this loaded

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.

Security

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 2mo 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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Guidance for AI coding agents working on this repository. Assumes no prior knowledge of the project.

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.

  • docs/agents/modules.md — per-module reference (the full Repository Layout table: every src/ module, page and css file — role, behavior contracts, ctx wiring, quirks, and its test suite)
  • docs/agents/testing.md — unit-test conventions and tests/helpers/ contracts, the Docker real-browser harness (smoke/keyboard/scrollbar gates + gotchas), manual testing checklist
  • docs/agents/release.md — release build/packaging detail, the two-step release process (git发布 + 商店发布 via the CWS API)
  • docs/agents/i18n.md — locale management flow (scripts/i18n.py, translate/verify gates)
  • docs/agents/quirks.md — verified known quirks, full text
  • docs/agents/design-laws.md — the visual/interaction laws distilled from repeated user feedback (right-edge 8px axis, 20px/24px icon-column geometry, staged glyph language, two-rung selecting bars, in-place flip sync…). READ BEFORE touching toolbars, row buttons or group heads

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: 4.1.3 (see manifest.json; package.json tracks 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; see docs/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.
