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 | $0.00197 | $0.02215 |
| Opus 5 | $0.00098 | $0.01107 |
| Sonnet 5 | $0.00039 | $0.00443 |
| Haiku 4.5 | $0.00020 | $0.00221 |
Grade A, and why
radical-simplification 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 yesterday.
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.

Radical Simplification — Cognitive Moves for Collapsing Complex Problems
Distillation of the documented working method of mathematicians, physicists, and engineers who consistently turn complex problems into simple solutions. The skill is not a step list — it is a toolbox of cognitive moves, each correcting a specific wrong default a capable model has when faced with complexity. The moves are mostly orthogonal; pick the one that matches the symptom.
This is the thinking layer that sits above refactoring (code-simplifier), metric design (deterministic-metric-design), and reviews (design-review). Those skills apply a methodology to a known shape of artifact. This skill is the methodology itself — how to arrive at the simple shape in the first place.
When to Apply
Use this skill when:
- The user says the problem feels too complicated, that the team is going in circles, or that there must be a simpler way
- A proposed design has accreted parameters, dependencies, or branches and feels overengineered
- A plan has been drafted but unresolved decisions remain, and the agent is about to commit to assumed answers
- A bug investigation has tried several variants of the same approach without progress
- A review surfaces complexity that may be accidental (Brooks) rather than essential
- The agent is asked to find an elegant solution to a hard engineering or product problem
- Forward search has exhausted and the agent needs a different angle (work backwards, invert, transfer from another domain)
- The agent is producing fluent-sounding output but cannot back it up under expansion (Feynman test)
This skill is not for cleaning up code that already does the right thing — that is code-simplifier. Use this when the approach itself is what needs to get simpler.
How to Use
The nine categories are orthogonal cognitive moves. Match the move to the symptom:
| Symptom | Reach for | First rule to read |
|---|---|---|
| Solving feels off — maybe the wrong problem | Frame | frame-restate-problem |
| Plan drafted but unresolved decisions remain | Clarify | clarify-interview-one-at-a-time |
| Drowning in cases, parameters, branches | Reduce | reduce-toy-case-first |
| Parts are tangled; changes ripple | Decompose | decomp-orthogonal-axes |
| Forward search is exponential or stuck | Invert | invert-work-backwards |
| Missing the structural truth of the system | Constrain | constrain-name-the-invariant |
| Stuck inside the current vocabulary | Transfer | transfer-cross-domain-analogue |
| The specific problem keeps resisting | Generalize | gen-rising-sea |
| Producing fluent output you cannot back up | Audit | audit-feynman-technique |

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.

radical-simplification is a skill published in the GitHub repository pproenca/dot-skills (200 stars, last pushed 16d ago), licensed MIT. It adds 197 tokens to every session and 2,215 once invoked, about $0.0010 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 2026-08-30.
