What it does

Session Optimizer is an agent skill from huangruiteng/CS-Notes. OpenClaw Session 优化器 - 监控 session 状态，在需要时提醒用户切换 session。包括 session 长度监控、已完成任务数量统计、时间显示等功能。

Its SKILL.md is about 260 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/session-optimizer.py`).

The licence is MIT.

Example prompts

“/session-optimizer”

Requirements

Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

Session 状态检查 - 检查当前 session 的运行时间
已完成任务统计 - 监控 TODO_ARCHIVE.md 中的归档任务数量
自动警告 - 在达到阈值时提醒用户
历史记录 - 记录 session 切换历史

What it can do on your machine

Read from SKILL.md and the folder at commit d01d8f8. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Session Optimizer loads about 257 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 77 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~27
When it runs · the whole SKILL.md, loaded when a task matches: ~257

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

The full file from huangruiteng/CS-Notes at commit d01d8f8, republished under its MIT licence (© huangruiteng). 77 words, ~257 tokens.
