tools

A command-line tool for running coding agents such as Claude Code, Codex, and Gemini CLI inside a development container, an isolated environment for software work.

In plain words
What is it for?
Creating and using a containerized workspace for AI-assisted software development.
Why use it?
It provides a repeatable container setup with selected API keys and persistent sign-in data for agent development.

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.

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

tools 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.

What it actually says

  • API keys (host-injected): OPENAI_API_KEY, ANTHROPIC_API_KEY, GEMINI_API_KEY are forwarded from the host shell when --stack agents is selected. Available to every process in the container.
  • Persistent auth volumes: ~/.claude, ~/.codex, ~/.gemini are named-volume mounts so OAuth / session state survives container rebuilds. (The Antigravity CLI / agy keeps its state under ~/.gemini/antigravity-cli/.)
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.

tools is an agent published in the GitHub repository morimorijap/sunaba-cli (3 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 120 tokens. 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.
