What it does

Sync is an agent skill from jdpolasky/ai-chief-of-staff. Mid-session checkpoint. Saves to memory, flags Command Center or To-Do drift, rotates session context.

Its SKILL.md is about 310 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation. It works with Obsidian. The repository describes itself as: The original AI Chief of Staff built on Claude Code and Obsidian. ADHD prosthetic, open to anyone. Superseded by chief-of-staff-2. The licence is MIT.

When your agent uses it

  • Productivity & Automation work in your project

Example prompts

  • “/sync”

What it can do on your machine

Read from SKILL.md and the folder at commit 832b784. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Sync loads about 313 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 162 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
~313

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); files beside SKILL.md are not scanned.

description
Mid-session checkpoint. Saves to memory, flags Command Center or To-Do drift, rotates session context.
user_invocable
true

Mid-session checkpoint. Optional. Most short sessions don't need it. Long sessions (2+ hours) usually do.

Save to memory

Update existing files in .claude/memory/ rather than creating new ones. The four core files are user_profile.md, preferences.md, projects.md, session_context.md. As the system grows, additional files follow the type-prefix convention (user_*.md, feedback_*.md, project_*.md, reference_*.md); see docs/memory.md.

For session_context.md: prepend the new entry at the top with today's date. Scan the file and remove any entries older than 7 days. Keep it current.

Check Command Center and To-Do drift

If something we worked on this session has shifted lane status, priorities, or the state check, propose specific edits and ask before making them. Don't edit silently.

If new tasks emerged or new waiting-for items came up, propose adding them to To-Do.md (rows in the Waiting For table for the latter) and ask before adding.

Keep it short. The point is to save the one or two real decisions from the last hour, not to rewrite everything.
