Chains by @dfinity v1.0.0 B PASS 1 flag

IC-specific security patterns for canister development in Motoko and Rust. Covers access control, anonymous principal rejection, reentrancy prevention (CallerGuard pattern), async safety (saga pattern), callback trap handling, cycle drain protection, and safe upgrade patterns. Use when writing or modifying any canister that modifies state, handles tokens, makes inter-canister calls, or implements access control.

Capabilities below are detected automatically by an open-source scanner that reads the skill's text and scripts (see how this is computed). Not measured means the scanner couldn't make a confident call — it is NOT a green check, and you should treat it as a possible red flag until a human or a stronger scanner has measured it.

1 Red flags things this skill can do that affect your security or funds

⚠
Requires private key you must hand over a private key, mnemonic, or wallet config

9 Cleared by scanner we scanned the skill's text & scripts and found no evidence of these

✓
Can move funds this skill can sign and send transactions on your behalf
✓
Requires hosted operator depends on a third-party hosted service to function
✓
Uses remote install script setup pipes a remote shell script (curl | sh class)
✓
Mutable remote runtime runs remote code that can change behavior without a local diff
✓
Can install code installs software at setup time (npx, pip, brew, etc.)
✓
Can execute shell runs arbitrary shell commands on your machine
✓
Can browse the web fetches arbitrary URLs at runtime
✓
Can write files writes to your local filesystem
✓
Can spawn sub-agents delegates to other skills or sub-agents

Auto-invocable may be invoked by the agent without your explicit prompt

Ingredients (services this skill talks to)

We did not find any well-known hosted services in this skill's text or scripts. This does NOT mean the skill is local-only — it might use services we don't yet recognize, or talk to them through code paths our scanner can't reach. A complete dependency list (every package, library, and binary, with integrity hashes) is on the roadmap; today we only show recognized hosts.

Audits

No one has audited this skill yet. That is different from “audited and clean” — it just means no professional reviewer (a security firm, the CryptoSkill team, or a verified independent researcher) has signed off on it. There are no audit reports to read. How reviewer levels work →
