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

anybox-start-dev 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/start-dev.ps1), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Anybox Start Dev

Use the bundled script to start the two long-running development processes required by this repository.

Workflow

  1. Run scripts/start-dev.ps1.
  2. Let the script open two new PowerShell 7 windows.
  3. Keep both windows open for the rest of the verification or testing session.

The script starts exactly these commands:

  • Server: cd <repo>/packages/anyboxagent && bun run dev:server
  • Client: cd <repo>/packages/desktop && bun run dev

Notes

  • Do not replace the commands with alternatives unless the user explicitly changes the workflow.
  • Start the two processes in separate windows; do not run one after the other in the same blocking shell.
  • If either window exits immediately, inspect the visible error in that window and report it before retrying.
  • The script resolves the repository root relative to the skill location, so keep this skill inside the project root at .anybox/skills/anybox-start-dev.

Resource

  • scripts/start-dev.ps1: Open the server and client in separate PowerShell 7 windows.
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
