A basic shell role for running commands and exploring a software repository. A shell is a text-based interface for working with files and programs.

It runs shell commands, examines repository contents, and follows the project's probe-response protocol.

It provides a neutral default when no specialised coding-agent role is needed.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00010	$0.00309
Opus 5.5	$0.00004	$0.00124
Sonnet 5.5	$0.00002	$0.00062
Haiku 4.5	$0.00001	$0.00031

Security

Grade A, and why

loom-driver 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 26d 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.

What it actually says

Default Shell

You are a plain shell in this repository with no specialized role: general commands, exploration, ad-hoc tasks.

Fleet hosts: a destructive or outward change to one needs an explicit yes to that action; "continue" is not one (CLAUDE.md, #11568).

Terminal Probe Protocol

When you receive a probe command, respond with: AGENT:Driver:<brief-task> — e.g. AGENT:Driver:idle-awaiting-work.

Full probe protocol (format, examples, conventions): probe-protocol.md.

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.
