rebase

rebase is a skill for Claude Code from drn/dots. It costs 35 tokens per session (1,245 once invoked), scanned A, original, MIT.

A branch-updating workflow that replays your commits on top of the latest version of the project's main branch and updates the remote pull request.

In plain words
What is it for?
Use it to rebase a branch onto the latest upstream default branch, resolve conflicts, and force-push the updated branch to its pull request.
Why use it?
It helps bring an older branch up to date and surfaces conflicts that must be resolved before merging.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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

rebase 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 1mo ago.

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.

  • HEAD ref: !git rev-parse --abbrev-ref HEAD 2>/dev/null | head -1
  • Open PR: !gh pr view --json number,url,headRefName 2>/dev/null | head -10

Your task

Rebase the current branch onto the latest upstream default branch and force-push to update the remote PR branch.

Step 0: Validate state

  • If HEAD is detached (not on a named branch), stop and tell the user: "Cannot rebase in detached HEAD state."
  • Determine the current branch name.

Step 1: Determine the target remote

  • Run git remote to list remotes.
  • If upstream exists, use upstream as the target remote.
  • Otherwise, use origin.

Step 2: Determine the default branch

If the user passed --onto <branch> in the arguments, use that branch as the rebase target instead of the default branch. Otherwise:

  • Run git symbolic-ref refs/remotes/<remote>/HEAD 2>/dev/null (where remote is from Step 1) and extract the branch name.
  • If that fails, check if <remote>/main exists with git rev-parse --verify <remote>/main 2>/dev/null.
  • If that fails, check if <remote>/master exists with git rev-parse --verify <remote>/master 2>/dev/null.
  • If none work, stop and tell the user: "Could not determine the default branch. Use --onto to specify."

If the current branch IS the default branch, stop and tell the user: "You are on the default branch. Rebase is not needed."

Step 3: Fetch

  • Run git fetch <remote> <default-branch>.
  • Report: "Fetching /..."

Step 4: Check if rebase is needed

  • Run git merge-base --is-ancestor <remote>/<default-branch> HEAD to check if already up to date.
  • If the branch is already up to date (exit code 0 from the above), report "Already up to date with /." and skip to Step 6.

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.
