Private calc stage B (square root). Invoked by stage A with the sum of squares as its argument; not user-invocable. Computes √s and hands off to stage C.

Use when the user says "netwatch" or asks to measure network stats (ping latency, packet loss, interface throughput) in the background. Launches a background subagent via the `task` tool that runs ~20s of measurements, then returns control immediately so the user can keep talking. Demonstrates background subagent invocation in opencode.
Private sieve subskill. Invoked by the sieve controller after each pass; not user-invocable. Reads sieve.state and draws the current grid — remaining primes vs. struck (composite) numbers.
Demonstrates cyclic skill invocation — runs the Sieve of Eratosthenes by invoking a private "strike" subskill once per prime, re-rendering a visual grid after each pass. Takes an upper limit n. Use to show one skill invoking another skill N times in a loop.
Private sieve subskill. Invoked by the sieve controller once per prime; not user-invocable. Strikes the multiples of a single prime p out of the sieve and records them in sieve.state.
Use when the user says "syscheck" or asks for a parallel system health check. Fans out THREE subagents at once via the Agent tool — one checks CPU, one network, one memory — using only safe read-only commands, then synthesizes their results into one report. Demonstrates parallel subagent fan-out in Claude Code.

You are running stage B of the calc pipeline. This skill is private
(user-invocable: false) — it was invoked by stage A, not by the user, with one
number as its argument ($ARGUMENTS): s, the sum of squares from stage A.
Do exactly this:
Let s = $ARGUMENTS. Compute the hypotenuse: h = √s.
Append this line to pipeline.log (do not overwrite what A wrote):
[B] square root: √<s> = <h>
Tell the user, in one line: Stage B: √<s> = <h> — handing off to C.
Invoke the calc-step-c skill, passing <h> (the hypotenuse) as its
argument.
Do only stage B's work plus the hand-off to C.
