dw-solo-skills: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from dominikwozniak/dw-solo-skills. Its token cost is not measured, scanned A, a copy of SessionStart, MIT.

Automatic checks that run before an agent uses shell commands or reads and edits project files. The listed checks guard shell use, block environment-file access, and protect plugin-managed files.

In plain words
What is it for?
Use them to apply safety checks before Bash commands, file reads, searches, edits, writes, and notebook changes.
Why use it?
They can stop risky or disallowed actions before they change the project or expose environment data.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR} variable. Also seen: names the NotebookEdit tool.

This is dominikwozniak/dw-solo-skills's own configuration. It tells Claude Code how to work on dw-solo-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dw-solo-skills configures →

One of 3 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 2 are separate, each on its own page.

Security

Grade A, and why

PreToolUse scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

53% identical to SessionStart — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
