Agent Memory

A persistent memory space for storing knowledge that survives across conversations.

Location: .claude/skills/agent-memory/memories/

Proactive Usage

Save memories when you discover something worth preserving:

• Research findings that took effort to uncover

• Non-obvious patterns or gotchas in the codebase

• Solutions to tricky problems

• Architectural decisions and their rationale

• In-progress work that may be resumed later

Check memories when starting related work:

• Before investigating a problem area

• When working on a feature you've touched before

• When resuming work after a conversation break

Organize memories when needed:

• Consolidate scattered memories on the same topic

• Remove outdated or superseded information

• Update status field when work completes, gets blocked, or is abandoned

Folder Structure

When possible, organize memories into category folders. No predefined structure - create categories that make sense for the content.

Guidelines:

• Use kebab-case for folder and file names

• Consolidate or reorganize as the knowledge base evolves

Example:

memories/ ├── file-processing/ │ └── large-file-memory-issue.md ├── dependencies/ │ └── iconv-esm-problem.md └── project-context/ └── december-2025-work.md

This is just an example. Structure freely based on actual content.

Frontmatter

All memories must include frontmatter with a summary field. The summary should be concise enough to determine whether to read the full content.

Required:

summary: "1-2 line description of what this memory contains" created: 2025-01-15 # YYYY-MM-DD format

Optional:

summary: "Worker thread memory leak during large file processing - cause and solution" created: 2025-01-15 updated: 2025-01-20 status: in-progress # in-progress | resolved | blocked | abandoned tags: [performance, worker, memory-leak] related: [src/core/file/fileProcessor.ts]

Search Workflow

Use summary-first approach to efficiently find relevant memories:

1. List categories

ls .claude/skills/agent-memory/memories/

2. View all summaries

rg "^summary:" .claude/skills/agent-memory/memories/ --no-ignore --hidden

3. Search summaries for keyword

rg "^summary:.*keyword" .claude/skills/agent-memory/memories/ --no-ignore --hidden -i

4. Search by tag

rg "^tags:.*keyword" .claude/skills/agent-memory/memories/ --no-ignore --hidden -i

5. Full-text search (when summary search isn't enough)

rg "keyword" .claude/skills/agent-memory/memories/ --no-ignore --hidden -i

6. Read specific memory file if relevant

Note: Memory files are gitignored, so use --no-ignore and --hidden flags with ripgrep.

Operations

Save

• Determine appropriate category for the content

• Check if existing category fits, or create new one

• Write file with required frontmatter (use date +%Y-%m-%d for current date)

mkdir -p .claude/skills/agent-memory/memories/category-name/

Note: Check if file exists before writing to avoid accidental overwrites

cat > .claude/skills/agent-memory/memories/category-name/filename.md << 'EOF'

summary: "Brief description of this memory" created: 2025-01-15

Title

Content here... EOF

Maintain

• Update: When information changes, update the content and add updated field to frontmatter

• Delete: Remove memories that are no longer relevant trash .claude/skills/agent-memory/memories/category-name/filename.md

Remove empty category folders

rmdir .claude/skills/agent-memory/memories/category-name/ 2>/dev/null || true

• Consolidate: Merge related memories when they grow

• Reorganize: Move memories to better-fitting categories as the knowledge base evolves

Guidelines

• Write self-contained notes: Include full context so the reader needs no prior knowledge to understand and act on the content

• Keep summaries decisive: Reading the summary should tell you if you need the details

• Stay current: Update or delete outdated information

• Be practical: Save what's actually useful, not everything

Content Reference

When writing detailed memories, consider including:

• Context: Goal, background, constraints

• State: What's done, in progress, or blocked

• Details: Key files, commands, code snippets

• Next steps: What to do next, open questions

Not all memories need all sections - use what's relevant.
