使用说明 (SKILL.md)

Memory Ebbinghaus

Ebbinghaus forgetting curve-based memory lifecycle manager. Tracks memory items with strength decay, review reinforcement, and archiving.

Setup

First run — initialize the database:

python3 scripts/ebbinghaus.py status
# Auto-creates memory_db.json in current directory if not found

To use a custom path:

EBBINGHAUS_DB=/path/to/memory_db.json \
EBBINGHAUS_ARCHIVE=/path/to/MEMORY.md \
python3 scripts/ebbinghaus.py status

Environment variables:

Variable	Default	Description
`EBBINGHAUS_DB`	`./memory_db.json`	Path to the JSON database
`EBBINGHAUS_ARCHIVE`	`./MEMORY.md`	File to append archived memories

Core Concept

Strength formula: strength = e^(-days_elapsed / stability)

Status	Strength	Meaning
🟢 Active	≥ 0.7	Recently used, clear memory
🟡 Decaying	0.3–0.7	Not used for a while
🔴 Fading	\x3C 0.3	Needs review or cleanup

Stability: starts at 1.0, multiplied by 1.5 on each review (the more you review, the slower it fades).

Commands

# View all memory items and their current strength
python3 scripts/ebbinghaus.py status

# Recalculate all strength values (run daily)
python3 scripts/ebbinghaus.py decay

# Add a new memory item
python3 scripts/ebbinghaus.py add "content description" --category \x3Ccat> --source \x3Corigin>

# Review and reinforce (resets strength to 1.0, stability ×1.5)
python3 scripts/ebbinghaus.py review \x3Cid>

# Delete a memory item
python3 scripts/ebbinghaus.py forget \x3Cid>

# Archive to MEMORY.md (removes from active list, appends to archive file)
python3 scripts/ebbinghaus.py archive \x3Cid>

# Heartbeat mode — print items needing attention
python3 scripts/ebbinghaus.py heartbeat

Heartbeat Integration

Add to your heartbeat config:

- Memory decay check: python3 /path/to/scripts/ebbinghaus.py heartbeat

Heartbeat output rules:

🔴 items exist → alert user, ask "review or forget?"
Only 🟡 items → log silently, no interruption
All 🟢 → output HEARTBEAT_OK

category	Meaning
`project`	Project/task completion
`tech`	Technical findings/solutions
`person`	Memory about someone
`event`	Important events
`general`	Other

Typical Workflows

"Clean up old memories":

Run decay then status
List 🔴 items, ask user: review / forget / archive?
Execute chosen action

"Remember this: XXX":

Run add "XXX"
Confirm added

"Which memories are fading?":

Run decay to update strengths
Run status, highlight 🔴 items

安全使用建议

This skill is internally coherent and implements a local memory manager. Before installing or running it: (1) review and keep a copy of the included scripts (you already have them); (2) run it in a safe directory (don't set EBBINGHAUS_DB or EBBINGHAUS_ARCHIVE to system or sensitive file paths); (3) back up any existing memory_db.json or MEMORY.md you care about; (4) if you plan to add this to an automated heartbeat, ensure the process runs with appropriate user permissions so it cannot write to protected system locations; (5) if you need the script to use the current working directory, update the environment-variable guidance or edit the DB_PATH default in the script to match your expectations.

功能分析

Type: OpenClaw Skill Name: memory-ebbinghaus Version: 1.0.0 The skill bundle provides a legitimate utility for managing an AI agent's memory using the Ebbinghaus forgetting curve. The Python script (ebbinghaus.py) performs local file operations to track, decay, and archive memory items in a JSON database and a Markdown file. There is no evidence of network activity, data exfiltration, or malicious command execution; the logic is transparent and strictly follows the functionality described in SKILL.md.

能力评估

ℹ Purpose & Capability

Name, description, SKILL.md, and the included Python script are consistent: the tool manages memory items with a forgetting-curve formula and supports add/review/decay/archive/forget/heartbeat. Minor documentation mismatch: SKILL.md lists the default DB path as './memory_db.json' (current dir) while the script's default is the repository root (parent of scripts/). This is an implementation/documentation divergence but not a functional mismatch.

✓ Instruction Scope

Runtime instructions and commands are narrowly scoped to local file operations and memory workflows. SKILL.md does not ask the agent to read unrelated system files, credentials, or contact external endpoints. Heartbeat integration simply runs the script and expects textual output.

✓ Install Mechanism

No install spec; this is instruction + included script. The script is plain Python, uses only stdlib, and requires no external downloads or package installs.

ℹ Credentials

The skill declares no required credentials and uses two optional environment variables (EBBINGHAUS_DB, EBBINGHAUS_ARCHIVE) to pick file paths. This is proportional to the purpose. Note: because these env vars accept arbitrary paths, a user (or misconfigured agent) could point them to sensitive or system files, causing accidental overwrite/appends; that is a usage risk rather than a hidden requirement.

✓ Persistence & Privilege

The skill does not request permanent 'always' inclusion, does not modify other skills, and does not alter agent-wide config. It writes only its own DB and archive files (paths configurable).
