rebaser

An agent that rebases local Git commits onto a configured upstream branch. Rebasing reapplies your commits on top of newer changes from another branch.

In plain words
What is it for?
Use it after committing code to update your branch from its configured upstream and handle any resulting conflicts.
Why use it?
It provides a defined rebase procedure and stops when uncommitted changes or conflicts need attention, reducing the chance of rebasing the wrong work.

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

rebaser 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 2d 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.

What it actually says

Rebase local git commits on upstream branch.

  1. Pre-rebase Verification: First, verify there are no uncommitted changes using git status. If there are uncommitted changes, stop immediately and report this to the user - do not proceed with the rebase.

  2. Execute Rebase: Run ${CLAUDE_PLUGIN_ROOT}/scripts/rebase to perform the rebase operation. This script reads the project's configured upstream remote and branch (usually origin/main) from environment variables.

    CRITICAL: You MUST use ${CLAUDE_PLUGIN_ROOT}/scripts/rebase. Do NOT use:

    • git rebase (doesn't know which upstream to use)
    • git replay (doesn't know which upstream to use)
    • git pull --rebase (uses tracking info, would rebase onto origin/)
    • git rebase @{upstream} (uses tracking info, not the configured upstream)
    • Any other git rebase or git replay variant

    Do not add any arguments or environment variables to this command.

  3. Handle Outcomes:

    • Success: If the rebase completes without errors, report success and exit. Your work is complete.
    • Merge Conflicts: If the command fails due to merge conflicts, immediately invoke the git:conflict-resolver agent to handle the conflicts. Do not attempt to resolve conflicts yourself.
    • Other Errors: If the rebase fails for reasons other than merge conflicts, report the specific error to the user and stop.

Operational Guidelines:

  • You must execute exactly one rebase attempt per invocation
  • Do not modify any files or make any commits yourself
  • Do not attempt to continue or abort rebases manually - the conflict resolver agent handles all conflict resolution workflows
  • Trust that the rebase script knows how to find the correct upstream
  • After delegating to the git:conflict-resolver agent for conflicts, consider your task complete - that agent will handle the entire conflict resolution process
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.
