Memfy

Save durable memory without secrets

Use this skill when the user says memfy, asks you to remember something for future chats, or asks you to persist durable local context.

Core Behavior

memfy is an explicit save-memory command. Treat it as permission to persist the important current-task details into the user's durable memory location.

Save only information that will help future agents avoid making the user repeat themselves:

• Stable preferences, workflows, decisions, contacts, project facts, IDs, URLs, file paths, and follow-up rules.
• Current task outcomes that future sessions should know.
• Corrections the user made that should change future behavior.
• Non-secret configuration names or environment variable names.

Do not save:

• Raw passwords, API keys, tokens, private keys, cookies, recovery codes, or full credentials.
• One-off emotional reactions, temporary drafting text, or noisy conversation.
• Sensitive personal data unless the user clearly wants it remembered and it is necessary for future work.
• Unsupported guesses. Mark uncertain facts as uncertain or do not save them.

Workflow

1. Identify the durable memory target.

   • Prefer MEMFY_MEMORY_FILE if it is set.
   • Otherwise read local project or agent instructions for a memory file path.
   • If no target is discoverable, ask the user where to save memory before writing.

2. Distill the memory.

   • Write concise bullet points under a dated heading.
   • Include exact file paths, URLs, IDs, and commands only when they are useful and non-secret.
   • Summarize secrets as location pointers such as "stored in .env under SERVICE_API_KEY"; never write the raw value.

3. Write safely.

   • Append to the existing memory file unless the user explicitly asks to edit or reorganize it.
   • Preserve the file's encoding when possible.
   • Do not overwrite unrelated memory.
   • If the memory file is unreadable because of encoding, use a safe append method that does not rewrite the full file.

4. Confirm briefly.

   • Tell the user what category of memory was saved.
   • Mention any important thing deliberately not saved, especially secrets.

Suggested Format

## Short Topic (YYYY-MM-DD)

- Stable fact, preference, or outcome.
- Relevant path or URL: `...`
- Secret handling note: raw credentials are stored only in `.env`, not in memory.

Quality Bar

A good memfy entry should be:

• Short enough to scan quickly.
• Specific enough for a future agent to act on.
• Free of raw secrets.
• Written in the user's own durable context, not only in the chat.
