# Skill Zero

Arm `zero` as the standing rung for this conversation. A session sits at exactly one rung.

Print the seven-rung line, marking `zero` as armed:

```text

zero · low · med · high · xhigh · max · ultra

```

- State that `zero` means no automatic summoning and manual `/summon` still works. If the user supplied the exact argument `all`, cut manual summon too and say so.

+ State that the default `temporary` cut means no temporary automatic summoning and manual `/summon` still works. If the user supplied the exact argument `all`, cut all skill summons, including manual `/summon`, and say so.

Already-loaded skills cannot be evicted mid-session. This instruction changes summoning behavior; it does not empty or restart the running session. Do not call the `summon` tool from this skill.

- No rung carries a count, no summon is capped, and no rung is gated or unratified. Heaven/Hell stamps are not built.

+ No rung carries a count and no summon is capped. Invocation metadata still distinguishes human-led Skill Heaven skills from model-led Skill Hell skills; zero changes whether either surface may summon, not the source classification.
