name	atuin-memory
description	Check, store, and retrieve project memories from atuin kv. Use when starting work on a project, recalling previous context, storing plans or specs, or when the user mentions memory, atuin, or project context.

Project Memory with Atuin

Store and retrieve project context using atuin kv to persist across sessions.

Project Detection

Reuse these variables in all commands:

PROJECT=$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || basename "$PWD")
BRANCH=$(git branch --show-current 2>/dev/null)
BRANCH=${BRANCH:-main}

Before Starting Work

echo "=== $PROJECT ($BRANCH) ==="

# Discover what memories exist for this project
atuin kv list --namespace "project-metadata" | grep -F "$PROJECT-" || echo "(no memories found)"

Then retrieve relevant memories:

# Empty output means memory doesn't exist
atuin kv get --namespace "project-metadata" "$PROJECT-$BRANCH-plan"
atuin kv get --namespace "project-metadata" "$PROJECT-$BRANCH-spec"
atuin kv get --namespace "project-metadata" "$PROJECT-$BRANCH-todo"

Acting on Retrieved Memories

- Check if stored plan/spec/todo still matches git state and current goals - Briefly summarize what you found so user can correct misunderstandings - Raise blockers, gaps, or open questions before proceeding—don't assume, ask - Pick up from first incomplete todo item; if none exist, start fresh - Update stored state after completing work so next session can resume cleanly

Storing Memories

For multi-line content, write to a temp file first to avoid shell escaping issues:

# 1. Write content to temp file
# 2. Store from temp file
atuin kv set --namespace "project-metadata" --key "$PROJECT-$BRANCH-plan" "$(cat /tmp/plan.md)"

# 3. Verify storage succeeded
atuin kv get --namespace "project-metadata" "$PROJECT-$BRANCH-plan" | head -5

For short single-line values, store directly:

atuin kv set --namespace "project-metadata" --key "$PROJECT-$BRANCH-status" "in-progress"

Key Naming

Key Pattern	Purpose
{project}-{branch}-plan	Implementation plans
{project}-{branch}-spec	Specifications/designs
{project}-{branch}-todo	Task state
{project}-{branch}-session-$(date +%Y-%m-%d)	Session summaries (use current date)

Deleting Memories

# Delete a specific key
atuin kv delete --namespace "project-metadata" "$PROJECT-$BRANCH-plan"

# Verify deletion (should return empty)
atuin kv get --namespace "project-metadata" "$PROJECT-$BRANCH-plan"

Quick Reference

Argument syntax is inconsistent across subcommands — pay attention to positional vs flag arguments:

Operation	Command	Notes
List all	atuin kv list --namespace "project-metadata"
Get	atuin kv get --namespace "project-metadata" "key"	KEY is positional
Set	atuin kv set --namespace "project-metadata" --key "key" "value"	KEY is --key flag, VALUE is positional
Delete	atuin kv delete --namespace "project-metadata" "key"	KEY is positional (not --key)

- Store artifacts in atuin, not local markdown files - Use /tmp for any temporary files needed during storage - Never commit metadata files to git
