dco

Recover from missing DCO sign-off on commits. Handles the single-commit amend, older-commit recovery via interactive rebase or cherry-pick, and explains the Probot DCO check that blocks PRs without sign-off. Use when a PR fails the DCO check, when a commit needs a Signed-off-by trailer added retroactively, or when sign-off was forgotten during rebase / cherry-pick / amend.

Quality

Content

82%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 well-structured, highly actionable body with executable commands for each recovery case and a verification step that addresses the destructive-history-rewrite risk. Minor conciseness trims and integrating verification as an in-flow checkpoint would lift it further.

Suggestions

Trim explanations Claude already knows (the --force-with-lease rationale and the 'What the Probot DCO check looks for' background) to push conciseness toward a 5.

Integrate the 'Verifying the whole branch' step as an explicit checkpoint inside Case 2 before the force-push, with a clear 'if N/B/E → fix and re-verify' feedback loop, rather than as a detached section.

Consider moving the Probot DCO background into a short reference note or collapsing it, since the description already promises it and it duplicates sign-off mechanism detail.

DimensionReasoningScore

Conciseness

Largely lean with targeted one-line explanations per code block and no padding, but contains minor over-explanation Claude likely already knows (e.g. '--force-with-lease is preferred over plain --force — it refuses if someone else has pushed' and the closing 'What the Probot DCO check looks for' background section).

4 / 5

Actionability

Provides fully executable, copy-paste-ready commands for every case (`git commit --amend --signoff -S --no-edit`, `git rebase -i <parent>`, `git cherry-pick --signoff <sha>`, the verification `git log --format=...`) covering the common recovery scenarios.

5 / 5

Workflow Clarity

Cases are clearly sequenced and the destructive rebase/force-push workflow includes an explicit verification step with code interpretation (G/U vs N/B/E), so it escapes the destructive-operation cap; however the verify section sits apart from the case flows rather than being an integrated checkpoint with an explicit fix-and-revalidate loop.

4 / 5

Progressive Disclosure

No bundle files exist and the ~70-line body is organized into clear navigable sections (Case 1/2/3, Verifying, Probot check) with the one external pointer ('.claude/rules/commit-workflow.md') clearly signaled; good structure, though there is no real overview-to-details split to push it to a 5.

Description

100%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 concretely names the recovery methods, includes natural third-person trigger phrasing covering the relevant synonyms, and clearly answers both what the skill does and when to use it.

DimensionReasoningScore

Specificity

Lists multiple concrete recovery actions — 'single-commit amend', 'older-commit recovery via interactive rebase or cherry-pick', plus 'explains the Probot DCO check' — giving comprehensive coverage of the recovery cases rather than vague abstraction.

5 / 5

Completeness

Explicitly answers both what ('Recover from missing DCO sign-off on commits. Handles the single-commit amend, older-commit recovery via interactive rebase or cherry-pick...') and when ('Use when a PR fails the DCO check, when a commit needs a Signed-off-by trailer added retroactively, or when sign-off was forgotten...').

5 / 5

Trigger Term Quality

Natural trigger phrases a user would actually say ('a PR fails the DCO check', 'Signed-off-by trailer added retroactively', 'sign-off was forgotten during rebase / cherry-pick / amend') with good synonym coverage (DCO, Signed-off-by, sign-off).

5 / 5

Distinctiveness Conflict Risk

Occupies a clear narrow niche (DCO sign-off recovery) with distinct triggers unlikely to fire for unrelated skills; minimal overlap risk with other git skills.
