extensions-disabled

extensions-disabled is an agent for coding agents from tintinweb/pi-subagents. It costs 9 tokens per session (74 once invoked), scanned B, original, MIT.

An end-to-end test case for a session where extensions are turned off.

In plain words
What is it for?
It is for testing sessions that should use only the agent's built-in tools.
Why use it?
It verifies that the agent does not expose extension tools when the session configuration disables them.

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 B, and why

extensions-disabled scanned grade B with 1 finding 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 4d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

What it actually says

e2e template: extensions are disabled, so only the built-in tools are active.

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.
