rebase

rebase is a skill for Claude Code from MarcusJellinghaus/mcp-tools-py. It costs 10 tokens per session (1,114 once invoked), scanned A, a copy of rebase, MIT.

A procedure for rebasing a Git feature branch, meaning replaying its changes on top of a newer base branch. It includes checks and guidance for resolving conflicts.

In plain words
What is it for?
For checking repository state, finding the base branch, rebasing a feature branch, resolving conflicts, and stopping safely when required checks fail.
Why use it?
It provides a controlled way to bring a branch up to date while handling conflicting edits and preserving the base branch's improvements.

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 6d 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.

Rebase Branch onto Base Branch

First Step

Call mcp__mcp-workspace__git with command "status" before doing anything else.

Rebase the current feature branch onto its base branch and resolve conflicts.

Core philosophy: Main is the source of truth. The feature branch adapts to main. For source code conflicts, preserve main's improvements and rework the feature branch code to fit.

Note on --ours/--theirs during rebase: --ours = main (the branch being rebased onto), --theirs = feature branch commits being replayed.

If the rebase becomes complex, suggest switching to cherry-picking as an alternative approach.

Determine Base Branch

Call mcp__mcp-workspace__get_base_branch to detect the correct base branch. Use the returned branch name in subsequent git commands.

Base Branch Confirmation

If the base branch is not main or master, ask the user to confirm before proceeding. Display the detected base branch and wait for explicit approval.

Pre-flight Checks (Abort if any fail)

  1. Working directory is clean (no uncommitted changes)
  2. Not already in rebase/merge state
  3. Not on main/master branch
  4. Remote origin exists
  5. pr_info/ does not exist on the base branch — if it does, abort with error: "pr_info/ exists on <BASE_BRANCH>. This folder should only exist on feature branches. Check your branch setup."

Workflow

  1. Call mcp__mcp-workspace__git with command "fetch" and args ["origin"]
  2. git rebase origin/${BASE_BRANCH}
  3. For each conflict:
    • If file is under pr_info/: auto-resolve with git checkout --theirs <file> (keep feature branch version), then git add <file> — no user input needed
    • For all other files: resolve manually, preserving main's improvements; rework feature branch changes to fit
    • Verify no conflict markers remain
    • git add <file>
    • git rebase --continue
  4. Run code checks: mcp__mcp-tools-py__run_pytest_check, mcp__mcp-tools-py__run_pylint_check, mcp__mcp-tools-py__run_mypy_check
  5. Fix any issues from merge
  6. Report summary and ask for user confirmation
  7. git push --force-with-lease

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.
