compact-core:compact-security
This skill should be used when performing a security review or audit of Compact smart contract code, or when reasoning about Compact's security threat model. Covers the three execution contexts (public ledger, ZK circuit, local witness), the witness trust boundary and the ownPublicKey()-for-authorization anti-pattern, sealed-field misuse, disclosure placement, information leakage via assert messages, cryptographic-primitive selection (transientHash/persistentHash/transientCommit/persistentCommit), domain separation, randomness reuse, and hash-derived authentication patterns. Routes to the compact-review checklists for granular line-items and defines the Verification Requests protocol used by the security-reviewer agent.

From the source SKILL.md
This skill provides the threat model and adversarial methodology for reviewing Compact smart contracts. It is the "how to think like an attacker" layer. For granular, item-by-item checklists, it routes to the existing compact-core:compact-review references (see the Reuse Map) — those are the single source of truth for line-items, and are not duplicated here.
What this skill does
compact-core:compact-security is a community-contributed Claude Code skill in the zero-trust sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/compact-security/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The compact-core:compact-security Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 163,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the compact-core:compact-security skill?
Use compact-core:compact-security when your Claude Code task falls under the Security category — specifically in the zero trust area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use compact-core:compact-security" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the compact-core:compact-security skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. compact-core:compact-security is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
