weizheng9493 Shared Memory
Overview
Use this skill to coordinate work across Codex and Claude through a shared local file store. The default memory directory is ~/Documents/ai-shared-memory/; set AI_MEMORY_DIR only when the user explicitly wants a different location.
The bundled scripts/memory.sh CLI writes structured Markdown entries, maintains memory-index.yml, and can create compact snapshots so either agent can read what the other agent already learned, decided, or completed.
Memory CLI
Use the script bundled with this skill:
scripts/memory.sh <command> [args...]
If the skill is installed with scripts/install.sh, a stable copy of the CLI is also placed at:
~/Documents/ai-shared-memory/scripts/memory.sh
Set AGENT_NAME before writing so memory entries show their source:
AGENT_NAME=codex scripts/memory.sh today
AGENT_NAME=claude scripts/memory.sh today
Start Of Work
At the start of each meaningful conversation or task, read shared context before acting:
export AGENT_NAME=codex # or claude
scripts/memory.sh today --tail 20
scripts/memory.sh recent 5
If the user names a project, repository, or workspace, also read its project memory:
scripts/memory.sh project <project-name>
When memory volume is small, it is acceptable to read broader context with today, index, or fact user-prefs. When memory volume becomes expensive, prefer today --tail 20, recent 5, today --summary, and project <name>.
When using prior memory in a user-facing answer, cite it inline as (来源: mem-xxx, codex) or (来源: mem-xxx, claude). If another agent already made a relevant decision, mention it so work does not repeat unnecessarily.
End Of Work
After completing substantial work, write only durable information. Before writing, ask whether a future Codex or Claude run would avoid repeated explanation or mistakes by seeing this memory.
scripts/memory.sh log "Completed <work summary>."
scripts/memory.sh decide <topic> "<title>" "<decision and rationale>"
scripts/memory.sh context <project> "<project context update>"
scripts/memory.sh context --replace <project> "<current project context>"
scripts/memory.sh fact user-prefs "<stable user preference or long-term fact>"
Choose the narrowest command:
log: completed work that another agent should know happened.decide: technical or product decisions and why they were chosen.context: repository, product, architecture, dependency, or workflow state. Usecontext --replacewhen the entry represents the current state rather than a historical update.fact: stable user preferences, long-lived constraints, or durable facts.
Use simple slug keys for <topic>, <project>, and <category>: letters, numbers, ., _, and - only. Do not include path separators.
Do not record temporary debug output, pure search results, routine failures, low-value intermediate steps, unconfirmed guesses, expired information, or casual chat. Do not record sensitive private information unless the user explicitly asks and the information is necessary; summarize it when possible.
Commands
Writing:
scripts/memory.sh log <message>
scripts/memory.sh decide <topic> <title> <body>
scripts/memory.sh context [--replace] <project> <content>
scripts/memory.sh fact <category> <content>
Reading:
scripts/memory.sh today [--tail N] [--summary] [--json]
scripts/memory.sh recent [n] [--json]
scripts/memory.sh project <project-name>
scripts/memory.sh search [--all] <query>
scripts/memory.sh list decisions|contexts|facts|logs|snapshots|projects
scripts/memory.sh index
Maintenance:
scripts/memory.sh snapshot [--force] [--recent N]
scripts/memory.sh archive
scripts/memory.sh delete <id>
scripts/memory.sh version
Installation
This folder is a complete skill. To install it for both agents from a cloned copy, run:
bash scripts/install.sh --both
The installer copies this folder into:
- Codex:
${CODEX_HOME:-$HOME/.codex}/skills/shared-memory - Claude:
${CLAUDE_HOME:-$HOME/.claude}/skills/shared-memory
The installer also initializes ~/Documents/ai-shared-memory/ and copies the CLI to ~/Documents/ai-shared-memory/scripts/memory.sh. It does not overwrite global instruction files. If a runtime does not auto-load skills, manually reference this SKILL.md or copy the folder to that runtime's user skill directory.
