handoff-mcp-hooks

Optional hooks for the Handoff MCP plugin that automatically add relevant project memories and linked documents to prompts and file edits. Hooks are actions that run automatically when specified events occur.

In plain words
What is it for?
Providing remembered project context and linked documentation whenever the coding agent receives a prompt or edits a file, when the required Handoff MCP plugin is installed.
Why use it?
They reduce the need to restate project history or manually attach related documents during each interaction.

Grade A, and why

handoff-mcp-hooks 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 yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

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.
