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 | $0.00044 | $0.02712 |
| Opus 5.5 | $0.00018 | $0.01085 |
| Sonnet 5.5 | $0.00009 | $0.00542 |
| Haiku 4.5 | $0.00004 | $0.00271 |
Grade A, and why
reasoning-router 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.
How it starts
The opening of the file, as written. The whole thing — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reasoning Router
Meta-reasoning layer: classify problems, dispatch to the optimal thinking MCP, monitor progress, re-route on stall. Minimize total tokens to a high-confidence conclusion.
Always uses the most advanced model (currently Opus 4.6). Meta-reasoning about how to think is the highest-leverage reasoning task.
Dispatch
$ARGUMENTS |
Action |
|---|---|
| Problem or question text | Route — classify and dispatch to optimal thinking method |
compare <problem> |
Compare — run 2-3 strategies on the same problem, pick best |
status |
Status — show current thinking session state |
switch <method> |
Switch — re-route to specified method mid-session |
recap |
Recap — summarize reasoning so far across all methods used |
methods |
Methods — show available methods with when-to-use cheatsheet |
| Empty | Guide — show routing cheatsheet and token tier table |
Classification
Run !uv run python scripts/problem-classifier.py "$ARGUMENTS"
for deterministic pre-scan, then refine with LLM judgment.
Axis 1 — Structure (what shape is the reasoning?)
| Structure | Signals | Primary Method |
|---|---|---|
| Decomposable | "break down", multi-hop, sub-questions | atom-of-thoughts |
| Sequential | "step by step", ordered process, debugging | sequential-thinking |
| Branching | "explore options", "what if", alternatives | cascade-thinking |
| Constrained | "given that", requirements, formal specs | shannon-thinking |
| Interconnected | dependencies, circular, complex system | atom-of-thoughts (full) |
| Creative | "brainstorm", "novel", "stuck", "reframe" | creative-thinking |
| Contradictory | paradox, "both true", tension, dilemma | lotus-wisdom |
| Investigative | "why did", root cause, debug, diagnose | crash |
Axis 2 — Complexity (how deep?)
| Complexity | Signals | Depth Control |
|---|---|---|
| Simple (1-3 steps) | Short input, single concept, "quick" | Tier 1 ONLY: aot-light or sequential |
| Moderate (4-8 steps) | Multiple factors, some uncertainty | Default depth, structure-matched method |
| Complex (9+ steps) | Cross-domain, high uncertainty | Full depth, extended steps |
| Wicked (open-ended) | No clear solution, values conflict | Composition patterns allowed |

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.

reasoning-router is a skill published in the GitHub repository wyattowalsh/agents (5 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 2,712 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 2026-09-03.
