Vibeyard is an IDE and project workspace for managing multiple AI coding-agent sessions, including parallel runs, split panes, task boards, cost tracking, and session resumption. It is for developers who use Claude Code, Codex CLI, or Gemini CLI and need to organize many agent-driven coding tasks. The catalogue add-ons provide commands, skills, and instructions for working with Vibeyard.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00100 | $0.01496 |
| Opus 5.5 | $0.00040 | $0.00598 |
| Sonnet 5.5 | $0.00020 | $0.00299 |
| Haiku 4.5 | $0.00010 | $0.00150 |
Grade A, and why
add-npm-dependency 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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adding an npm Library
This is an Electron app with three separate build targets (main, preload, renderer) and a few non-obvious bundling rules. Adding a dependency the wrong way silently breaks CSS, native modules, or the renderer bundle. Follow this guide every time.
Golden Rule: install the latest, caret-pinned
Always install the newest published version. Never hand-edit package.json to set or downgrade a version.
npm install <pkg>@latest # runtime dependency
npm install -D <pkg>@latest # dev / build-only tool (types, bundlers, test libs)
- This records a caret range
^x.y.z— the repo convention (every dep inpackage.jsonuses^). Leave it as a caret range. package-lock.jsonis committed and gets updated by the install. Bothpackage.jsonandpackage-lock.jsonare part of your change — stage both.- Use npm only (the lockfile is
package-lock.json— not yarn, not pnpm). - Node v24 is pinned in
.nvmrc;engines.nodeis>=18. Runnvm usefirst if needed.
Step 1 — Decide which build target consumes the package
This determines every gotcha that follows.
| Target | Source dirs | How it's built | What's allowed |
|---|---|---|---|
| Renderer | src/renderer/** |
Bundled by esbuild into one IIFE (build:renderer) |
Plain JS/TS deps only. No Node built-ins, no native modules. |
| Main | src/main/**, src/shared/** |
tsc → CommonJS (dist/main/) |
Any Node dep, including native modules. Resolved via require at runtime against node_modules — not bundled. |
| Preload | src/preload/**, src/shared/** |
tsc → CommonJS (dist/preload/) |
Runs in Node/Electron context; same rules as main. |
- A pure JS/TS library used in the UI (like
marked,dompurify,gridstack,@xterm/*) just getsimported in renderer code and esbuild bundles it. Nothing else to do (except CSS — see Step 2). - A library that touches the filesystem, spawns processes, or has a
.nodebinary belongs in main/preload only.
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.

add-npm-dependency is a skill published in the GitHub repository elirantutia/vibeyard (1,388 stars, last pushed 1mo ago), licensed MIT. It adds 100 tokens to every session and 1,496 once invoked, about $0.0004 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 2026-08-30.

Ask one useful structured question at a time only when material product/implementation choices are genuinely missing; remember answers and produce a brief/spec. Discoverable facts should be investigated instead of asked.

Create a Google Meet meeting space and share the join link.
refocusing
Use when a long-running agent may have lost the product outcome, when context was compacted, when work has crossed a major boundary, or when a fresh path-based trace is needed before the next consequential action. Not for fresh-session orientation, waking an idle seat, or checkpoints.

Author or run durable BB workflows when the user requests workflow execution or multi-agent orchestration.
