A plugin description for adding long-term Hindsight memory to ZCode and Claude Code. It recalls relevant context before prompts and saves conversations after turns without using MCP.

Use it to add automatic memory recall and conversation saving to ZCode or Claude Code, including support for the Hindsight-related configuration and hooks.

It lets these coding assistants carry useful context between sessions without requiring direct MCP tools.

Security

Grade A, and why

zcode 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.
