What it does
Simplification Cascades is an agent skill from sandgardenhq/sgai. Find one insight that eliminates multiple components - "if this is true, we don't need X, Y, or Z". Code has many similar-looking implementations. Growing list of special cases. Same concept handled 5 different ways. Excessive configuration. Many if/else branches doing similar things. Complexity spiraling.
Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Sandgarden AI Software Factory.
Example prompts
- “if this is true, we don”
- “/simplification-cascades”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- List the variations - What's implemented multiple ways?
- Find the essence - What's the same underneath?
- Extract abstraction - What's the domain-independent pattern?
- Test it - Do all cases fit cleanly?
- Measure cascade - How many things become unnecessary?
What it can do on your machine
Read from SKILL.md and the folder at commit 9efbb7b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Simplification Cascades loads about 725 tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 315 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 315 words (~725 tokens).
“Sometimes one insight eliminates 10 things. Look for the unifying principle that makes multiple components unnecessary.”
