The Claude Code plugin registers lifecycle hooks so memory is captured automatically. You do not have to call memory_save for routine work; the hooks observe tool use, prompts, and session boundaries and write observations for you.

Quick start

Install the plugin and the hooks register themselves:

/plugin marketplace add rohitg00/agentmemory
/plugin install agentmemory

Watch observations land live at http://localhost:3113.

What the hooks do

• Session start and end frame each unit of work and let handoff resume it.
• Tool-use hooks capture what changed and why, the raw material for recall and recap.
• Prompt-submit captures intent. Pre-compact preserves context before the host trims it.
• A post-commit hook links commits to sessions, which powers commit-context and commit-history.

Important

• Capture is on by default and is zero-LLM. Turning observations into LLM summaries (AGENTMEMORY_AUTO_COMPRESS) and injecting them back into context (AGENTMEMORY_INJECT_CONTEXT) are separate opt-ins because they spend tokens.
• If observations are missing, confirm the plugin is enabled and the server is running. See ../_shared/TROUBLESHOOTING.md.

See also

• agentmemory-config for the capture and injection flags.
• The handoff, recap, and session-history skills consume what these hooks record.
