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 | $0.00047 | $0.00872 |
| Opus 5.5 | $0.00019 | $0.00349 |
| Sonnet 5.5 | $0.00009 | $0.00174 |
| Haiku 4.5 | $0.00005 | $0.00087 |
Grade A, and why
model-dispatch 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 1mo 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.

Sounio Model Dispatch Guide
Workflow
- Identify the task type from the Decision Flowchart or Quick Reference table below.
- Assign the task to the indicated model.
- If the result is uncertain or the first attempt fails, escalate via the Fallback Chain.
- For multi-file compiler changes that touch formal semantics, enable Multi-Model Review.
Decision Flowchart
- Touches 3+ files across compiler stages? -> Opus 4.6
- Requires formal reasoning / soundness? -> Opus 4.6
- Long autonomous run or prose writing? -> GPT-5.3-Codex
- Whole-codebase sweep or impact analysis? -> Gemini 3.1 Pro
- System-level debugging or cross-check? -> GLM-5
- Render example completion (self-contained, no imports)? -> Sonnet 4.6
- Touches self-hosted frontend (check/resolve) + correctness proof? -> Opus 4.6
- PGO pass (IR module, new opcodes, self-test)? -> Opus 4.6
- Website/docs/skills update? -> Sonnet 4.6
- Native backend single-file pass (peephole/frame/encode)? -> Sonnet 4.6
- Multi-file native pipeline change (codegen+lower_ir+encode)? -> Opus 4.6
- Everything else -> Sonnet 4.6

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

model-dispatch is a skill published in the GitHub repository Sounio-lang/sounio (12 stars, last pushed today), licensed Apache-2.0. It adds 47 tokens to every session and 872 once invoked, about $0.0002 per session on Opus 5.5. 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.
