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 | $0.00037 | $0.01154 |
| Opus 5 | $0.00018 | $0.00577 |
| Sonnet 5 | $0.00007 | $0.00231 |
| Haiku 4.5 | $0.00004 | $0.00115 |
Grade A, and why
routing-confidence-probe-promotion 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 12d 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.

Routing confidence and probe promotion

Use this skill when working on:
- input routing
- AVB/stagebox routing
- AUX/monitor sends
- FX sends
- subgroup/main assignments

Goal
Never present uncertain routing as verified routing. A consuming sound-engineer agent must be able to distinguish what the MCP backend directly observes, what it infers, what requires probe evidence, and what cannot be known through the current adapter.
Routing confidence vocabulary
Use these exact values in schemas, docs, and tests where practical:
| Value | Meaning |
|---|---|
observed_live_state |
Directly read from live mixer state keys. |
inferred_live_state |
Derived from key patterns or normalized mappings, not directly confirmed. |
probe_verified |
Confirmed by operator-driven probe/diff on real hardware. |
probe_required |
Must not be trusted until probe/diff is run. |
not_verifiable_with_current_adapter |
Current adapter/protocol surface cannot expose this fact. |
stub |
Tool intentionally returns limited result or instructions only. |
unsupported |
Not implemented and not planned for current scope. |
Do not use vague values such as ok, complete, works, unknown, or probably.
Layer model
Layer A — observable live state
Allowed without probe, but may still be inferred_live_state:
- channel names
- mute/solo/fader/pan where mapped
- meter activity
- AUX send level/assign when exposed by live keys
- FX send level/assign when exposed by live keys
- subgroup/main assignment when exposed by live keys
Layer B — hardware/probe-dependent routing
Must be probe_required, probe_verified, or not_verifiable_with_current_adapter:
- physical input source routing
- AVB stream routing
- stagebox socket to mixer-channel routing
- output patch source names where only source indices are known
- bus-to-output source-name mapping
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.

routing-confidence-probe-promotion is a skill published in the GitHub repository zarfld/presonus-studiolive-mcp (1 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 1,154 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 2026-08-31.
