What it does
Cryptominisat is an agent skill from msoos/cryptominisat. Solve Boolean satisfiability (SAT) problems with the pycryptosat Python library. Use when a problem can be expressed as Boolean variables and logical constraints — e.g. "is this set of rules consistent?", "find an assignment satisfying these conditions", "are these requirements contradictory?". CMS is a pure SAT solver: it answers SAT/UNSAT over CNF (AND-of-ORs) clauses, with native support for XOR (parity) constraints. Do NOT use it directly for integer/real arithmetic or optimization — see "When NOT to use…
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Python. The repository describes itself as: An advanced SAT solver.
When your agent uses it
- A problem can be expressed as Boolean variables and logical constraints — e.g
Example prompts
- “is this set of rules consistent?”
- “find an assignment satisfying these conditions”
- “are these requirements contradictory?”
- “/cryptominisat”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Model the problem as Boolean variables and clauses (CNF).
- Solve it with pycryptosat.Solver.
- Decode the solver's answer back into the original problem's terms.
What it can do on your machine
Read from SKILL.md and the folder at commit 2bf89cf. 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
Shell commands in SKILL.md call:
pip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
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
Cryptominisat loads about 1.9k tokens when it runs. Until then it costs about 135 tokens; SKILL.md has 779 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 779 words (~1,861 tokens).
“CryptoMiniSat is a Boolean SAT solver. Your job as the agent is to:”
