SessionStart

SessionStart is a hook for coding agents from noviq-ai/google-analytics-mcp. Its token cost is not measured, scanned A, original, Apache-2.0.

Two automatic checks that run when a session starts or is compacted. They check whether Google Analytics credentials exist and remind the agent how to request Google Analytics 4 reports.

In plain words
What is it for?
Use it with the Google Analytics MCP server to check the service-account file and recall how to find property IDs and run historical or live reports.
Why use it?
They warn about missing access credentials and preserve useful instructions when the session context is shortened.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add hooks/noviq-ai/google-analytics-mcp/session-start
Clone the repo
git clone --depth 1 https://github.com/noviq-ai/google-analytics-mcp

Or install google-analytics-mcp, the plugin that ships this one along with the rest of its 2 skills, 1 agent, 1 hook, 1 MCP server.

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 4d 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.

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.
