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 | $0.00043 | $0.01393 |
| Opus 5 | $0.00022 | $0.00696 |
| Sonnet 5 | $0.00009 | $0.00279 |
| Haiku 4.5 | $0.00004 | $0.00139 |
Grade A, and why
GA Probe scanned grade A 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 5d 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.

/ga probe — GA Chatbot Probe
Use this sub-command when you need to test agent behaviour, compare routing decisions, or get music theory answers from the live GA chatbot (Ollama-backed, SemanticRouter-dispatched).
When to Use
- Testing that
SemanticRouterpicks the right agent for a given query - Comparing how
TheoryAgentvsCriticAgentanswer the same question - Getting a real chatbot answer as context while writing code
- Verifying a newly deployed agent change works end-to-end
- Confirming orchestrator-level skills short-circuit routing (
routingMethod: "orchestrator-skill")
Single Agent Query
curl -sk -X POST https://localhost:7001/api/ga/eval \
-H "Content-Type: application/json" \
-d "$(jq -n --arg q "What intervals make up a Cmaj7 chord?" \
'{script: ("invoke \"agent.theoryAgent\" (Map.ofList [\"question\", box " + ($q | @json) + "])")}')"
Or in a GAL script:
invoke "agent.theoryAgent" (Map.ofList ["question", box "What intervals make up a Cmaj7 chord?"])
The SemanticRouter inside the GA API picks the best specialist (Theory / Tab / Critic / Composer) based on embedding similarity. The agent closure does not force a specific agent — routing still happens at the API level.
Fan-Out: Compare Multiple Agents
To send the same question to multiple agent closures in parallel and collect all answers:
invoke "agent.fanOut" (Map.ofList [
"question", box "Analyse the progression Am - F - C - G"
"agentNames", box [| "agent.theoryAgent"; "agent.criticAgent" |]
])
Returns Map<string, string> — agent name → response. Display side-by-side.
Direct Chatbot Endpoint (no GAL)
For debugging routing metadata (agent selected, confidence, routing method):
curl -sk -X POST https://localhost:7001/api/chatbot/chat \
-H "Content-Type: application/json" \
-d '{"message": "Show me fingering for an open G chord", "useSemanticSearch": true}' \
| python -m json.tool
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.

GA Probe is a skill published in the GitHub repository GuitarAlchemist/ga (2 stars, last pushed today), licensed MIT. It adds 43 tokens to every session and 1,393 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
