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 | $0.00051 | $0.00337 |
| Opus 5 | $0.00026 | $0.00169 |
| Sonnet 5 | $0.00010 | $0.00067 |
| Haiku 4.5 | $0.00005 | $0.00034 |
Grade A, and why
router-learning-system 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 6d 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
Router Learning System
一句總結
Router 係心臟。你俾個任務，Router 自動揀最快最可靠嘅方法執行。 每次使用自動學習，越用越知邊條 path 最快。
核心功能
- 五層 Routing: CLI (T1) → CDP (T2) → Browser (T3) → Cua (T4) → Vision (T5)
- RouterHistoryDB: SQLite 自動記錄每次 routing 結果
- 動態排序: ≥5 samples 後按歷史 performance 排序 paths
- Fail 跳過: 連續 3 次 fail 嘅 path 自動 skip
- 冷啟動兼容: 冇歷史 data 時用 static tier order
用法
from router import do, route, history_stats
# 一句搞掂
result = do("create_github_token", args={"note": "my-token"})
# 查學習統計
stats = history_stats("create_github_token")
技術棧
- Python 3.13+
- SQLite (macOS built-in)
- Zero external dependencies
What ships with it
1 file 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.

router-learning-system is a skill published in the GitHub repository ChrisLamDev/hermes-core-skills (9 stars, last pushed 2mo ago), licensed MIT. It adds 51 tokens to every session and 337 once invoked, about $0.0003 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.

This chat has a shared, live TODO plan — your tasks for the conversation, which the user also edits. Read this skill and reach for the todo tools whenever a request takes more than a couple of steps. It covers the plan model (group = task, items = its steps; loose items are the user's lane), how to work it: propose…
