What it does
Sc Hypothesize is an agent skill from kylesnowschwartz/SimpleClaude. Use when multiple plausible approaches must be generated, tested, and compared against constraints before the user chooses.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `examples/architecture-decision.md`, `references/adi-cycle.md` and `references/evidence-quality.md`).
The repository describes itself as: Practical minimalism for AI assisted programming with Claude Code.
When your agent uses it
- Multiple plausible approaches must be generated
- Compared against constraints before the user chooses
Example prompts
- “/sc-hypothesize”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Abduction (Generate Hypotheses)
- Deduction (Verify Logic)
- Induction (Gather Evidence)
- Decision (User Decides)
What it can do on your machine
Read from SKILL.md and the folder at commit a98f931. 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
Sc Hypothesize loads about 1.9k tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 35 tokens; SKILL.md has 742 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 742 words (~1,870 tokens).
“Reason through problems by generating competing hypotheses, verifying them against constraints, gathering evidence, and presenting a comparison for the user to decide.”

Can I use Sc Hypothesize in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add kylesnowschwartz/SimpleClaude --skill sc-hypothesize -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/sc-hypothesize, .gemini/skills/sc-hypothesize, .github/skills/sc-hypothesize and .opencode/skills/sc-hypothesize in your project.
What does Sc Hypothesize need to run?
SKILL.md names no scripts, command-line tools or credentials: Sc Hypothesize is instructions for the agent only.
Does Sc Hypothesize access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Sc Hypothesize safe to install?
