Defi Incident Analysis

Q: What is a Claude Code skill and how does the Defi Incident Analysis 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. Defi Incident Analysis is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.

How Defi Incident Analysis fits the catalog

Defi Incident Analysis sits in the Security category under the identity-access sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

Is Defi Incident Analysis safe to install?

A free static scan flagged 1 of ten categories (supply-chain), including a high-severity pattern. Read the security scan below before installing — a pattern inside a code fence is weighted as an example, not an instruction.

Installing & verifying

Installing Defi Incident Analysis writes its SKILL.md to ~/.claude/skills/defi-incident-analysis/SKILL.md; Claude Code discovers it automatically on the next session — no restart flag needed. It declares no allowed-tools restriction, so it inherits your session’s existing tool access rather than narrowing it. To confirm it loaded, ask Claude to list its available skills — defi-incident-analysis should appear by name.

What Defi Incident Analysis needs to run

External services: The SKILL.md references pricing, quota, or rate limits — it likely calls a paid or rate-limited API. Check the source before wiring it into unattended automation.
Prerequisites: Ships its own installation / prerequisites section — it isn’t purely self-contained; read that first.
Scope discipline: Declares explicit “when not to use” boundaries — safer than average to hand to an autonomous agent, which is less likely to over-apply it.
Worked code: 20 copy-paste code blocks in the body.
Depth: ~9,281 words, substantial — top of the catalog distribution.

When to reach for it

There are 10 related skills in Security — a two-minute scan of the alternatives usually confirms whether Defi Incident Analysis is the right pick.
