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.

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 | $0.00034 | $0.00449 |
| Opus 5 | $0.00017 | $0.00225 |
| Sonnet 5 | $0.00007 | $0.00090 |
| Haiku 4.5 | $0.00003 | $0.00045 |
Grade A, and why
mux 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 8d 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
mux
This skill is a package-owned trigger alias for ac-workflow-mux. It is not an independent workflow definition.
Delegate workflow semantics to ../ac-workflow-mux/SKILL.md and runtime semantics to ../../extensions/pimux/docs/.
Mandatory trigger behavior
If the user explicitly triggers mux, the parent must actually run through pimux.
Required sequence:
- after spawn, do not poll pimux or use Bash sleep/wait loops; wait for delivered child bridge activity
- treat the authoritative
pimuxextension as the fail-closed parent control-plane lock - prepare bounded handoff from the user request only
- spawn the authoritative
pimuxchild before substantive analysis - keep the parent control-plane only; use
AskUserQuestiononly for explicit user clarification - after spawn, run notify-first rather than poll-first: do not call
status,capture,tree,list, oropenon the happy path - after a child progress report, use at most one
send_messageif input is needed, then wait again - use
status/capture/tree/list/openonly for explicit live inspection, suspected stall/protocol violation/failure, or the inactivity watchdog - after terminal settlement, do one final
pimux statusverification and then advance
Do not satisfy mux requests by directly doing domain work in the parent.
Do not use parent-side Read, Bash, or repo inspection to figure out the task before spawn.
Do not poll pimux or use Bash sleep/wait loops; wait for delivered child activity, and treat status / capture / tree / list / open as recovery-only.
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.

mux is a skill published in the GitHub repository WaterplanAI/agentic-config (30 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 449 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-30.
