SessionStart

SessionStart is a hook for Claude Code from ProductOfAmerica/mcp-server-kicad. Its token cost is not measured, scanned A, a copy of SessionStart, GPL-3.0.

A startup hook that runs a shell check when a Claude Code session starts, resumes, is cleared, or is compacted. A hook is an automatic action tied to one of these session events.

In plain words
What is it for?
It helps run the ProductOfAmerica KiCad server's session-start check during those Claude Code events.
Why use it?
It performs the configured session-start check automatically instead of requiring a manual command.

Hook for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Part of the kicad plugin — 6 skills, 3 agents, 2 hooks, 1 MCP server shipped together

One of 2 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

Good fit It helps run the ProductOfAmerica KiCad server's session-start check during those Claude Code events.

Security

Grade A, and why

SessionStart 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 2mo 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

88% identical to SessionStart, 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.
