sync-upstream

Update a stale session branch by rebasing onto the latest origin. Use when the upstream has moved significantly and the session needs to catch up, resolving conflicts by preserving upstream changes and adapting session work to fit.

Quality

Content

86%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A tight, well-structured skill body with executable commands and a sensible upstream-wins conflict policy. The only weakness is that the post-rebase validation step is described abstractly rather than with a concrete verification command.

Suggestions

Make the Validation step actionable by naming a concrete check (e.g. run the build/test command or `git status`/`git log` to confirm the rebase result) instead of "verify the result still compiles".

Add a brief note on how to abort safely (e.g. `git rebase --abort`) so Claude has an explicit recovery path if conflicts become unmanageable.

Clarify how to detect that the upstream "has moved significantly" (e.g. compare branch divergence) so the trigger for invoking the skill is unambiguous.

DimensionReasoningScore

Conciseness

Lean and efficient with no concept-padding; every line (workflow, conflict rules, validation) earns its place and assumes Claude's competence with git.

5 / 5

Actionability

Provides concrete executable commands (git fetch, rebase, add, rebase --continue) and references the /commit skill; the validation step ("verify the result still compiles") lacks a concrete command, leaving a minor gap.

4 / 5

Workflow Clarity

A clear numbered sequence with a conflict-resolution feedback loop (add + rebase --continue) and a validation section; the validation checkpoint is present but not concrete, and the rebase is history-rewriting, so it does not quite reach the explicit-feedback-loop anchor.

4 / 5

Progressive Disclosure

A single-purpose skill under 50 lines with no external references needed and well-organized sections (Workflow, Conflict Resolution, Validation), satisfying the simple-skill exception for a top score.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that answers both what and when with natural trigger phrasing and a clear upstream-wins conflict policy. Minor room for improvement only in trigger-term synonym coverage.

DimensionReasoningScore

Specificity

Names the domain (git rebasing) and several concrete actions — "rebasing onto the latest origin", "resolving conflicts by preserving upstream changes and adapting session work" — with only minor coverage gaps.

4 / 5

Completeness

Clearly states what it does ("Update a stale session branch by rebasing onto the latest origin") and gives an explicit "Use when..." trigger with concrete conditions, satisfying both what and when.

5 / 5

Trigger Term Quality

Includes natural phrases users would say ("stale session branch", "upstream has moved significantly", "session needs to catch up"); a few common synonyms like "sync" or "up-to-date" are missing, so it sits just below the comprehensive anchor.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear niche — catching up a session branch via rebase with an upstream-wins conflict policy — with distinct triggers and minimal overlap with other skills.
