sync-worktree

A command for updating a Git worktree, which is a separate working copy of a Git repository, with the latest changes from the main branch.

In plain words
What is it for?
Use it to fetch main, rebase the current worktree onto it, and report any conflicts without force-pushing or changing the main branch.
Why use it?
It checks that the worktree is clean, preserves local commits, and stops safely if uncommitted changes or rebase conflicts make the update unsafe.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sync-worktree scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Safely update the current worktree with latest changes from main.

Prerequisites

  • Must be in a git worktree (not the main working directory)
  • Working directory should be clean (no uncommitted changes)

Steps

  1. Verify we're in a worktree: git worktree list
  2. Check for uncommitted changes: git status --porcelain
  3. If changes exist, warn user and STOP
  4. Fetch latest: git fetch origin main
  5. Rebase current branch onto main: git rebase origin/main
  6. Report result

On Conflict

If rebase conflicts occur:

  1. Report conflicting files
  2. Abort rebase: git rebase --abort
  3. Suggest manual resolution or merge strategy

Safety

  • Never force push
  • Never modify main branch
  • Always preserve local commits
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
