EchoVault — Agent Memory System

You have persistent memory across sessions. USE IT.

Session start — MANDATORY

Before doing ANY work, retrieve context from previous sessions:

memory context --project

If the user's request relates to a specific topic, also search for it:

memory search "<relevant terms>"

When search results show "Details: available", fetch them:

memory details <memory-id>

Do not skip this step. Prior sessions may contain decisions, bugs, and context that directly affect your current task.

Session end — MANDATORY

Before ending your response to ANY task that involved making changes, debugging, deciding, or learning something, you MUST save a memory. This is not optional. If you did meaningful work, save it.

memory save \
  --title "Short descriptive title" \
  --what "What happened or was decided" \
  --why "Reasoning behind it" \
  --impact "What changed as a result" \
  --tags "tag1,tag2,tag3" \
  --category "<category>" \
  --related-files "path/to/file1,path/to/file2" \
  --source "claude-code" \
  --details "Full context with all important details. Be thorough.
             Include alternatives considered, tradeoffs, config values,
             and anything someone would need to understand this fully later."

Categories: decision, bug, pattern, setup, learning, context.

Use --source to identify the agent: claude-code, codex, or cursor.

What to save

You MUST save when any of these happen:

• You made an architectural or design decision
• You fixed a bug (include root cause and solution)
• You discovered a non-obvious pattern or gotcha
• You set up infrastructure, tooling, or configuration
• You chose one approach over alternatives
• You learned something about the codebase that isn't in the code
• The user corrected you or clarified a requirement

What NOT to save

• Trivial changes (typo fixes, formatting)
• Information that's already obvious from reading the code
• Duplicate of an existing memory (search first)

Agent setup (recommended)

Run once to auto-install hooks for your agent:

memory setup claude-code   # or: cursor, codex

To remove: memory uninstall claude-code

Other commands

memory config       # show current configuration
memory sessions     # list session files
memory reindex      # rebuild search index
memory delete <id>  # remove a memory

Rules

• Retrieve before working. Save before finishing. No exceptions.
• Always capture thorough details — write for a future agent with no context.
• Never include API keys, secrets, or credentials.
• Wrap sensitive values in <redacted> tags.
• Search before saving to avoid duplicates.
• One memory per distinct decision or event. Don't bundle unrelated things.
