Retrieve relevant past memory. Call this tool before you answer the user. Use it when the user references past work or when the task needs project context.

Save a decision, a learning, or a task outcome to memory. Call this tool after you complete a non-trivial task, make a decision, or fix a bug with a known root cause. You can capture a single text string, or a list of role-based conversation messages.

Search memory by keyword or by semantic similarity. Use this tool when recall is too broad and you need specific facts.

Delete specific memory entries. Use this tool only when the user requests a deletion. Do not auto-forget.

Resolve a conflict between two captures. Mark one as the winner and the other as stale. Call this tool when capture reports a conflict between two memories.

Write a structured handoff packet for the next agent session. Call this tool at the end of a session, or before you switch to a different agent. The next agent calls recall to load this packet and continue without re-reading files. This saves 60-85% of tokens compared to re-discovering context.

Record an Architecture Decision Record (ADR). Use this tool when you make a technical decision that future agents should know about. The ADR is stored as a structured capture and can be recalled by any agent working on the same project.
