// Compare a pull request's implementation against spec context in spec_context.md and feed any material mismatches into review.json. Use during PR review when approved or repository spec context is available.
Create a product spec from a GitHub issue in this repository by applying the local shared `write-product-spec` workflow with Oz-specific issue context and output paths. Use when an issue should be turned into a product spec artifact stored under `specs/GH<issue-number>/product.md` and the agent should prepare file changes only, without creating commits or pull requests itself unless the prompt explicitly asks for it.
Create a technical spec from a GitHub issue in this repository by applying the local shared `write-tech-spec` workflow with Oz-specific issue context and output paths. Use when an issue should be turned into a tech spec artifact stored under `specs/GH<issue-number>/tech.md` and the agent should prepare file changes only, without creating commits or pull requests itself unless the prompt explicitly asks for it.
Detect duplicate GitHub issues by comparing the incoming issue's title and description against the repository issue list. Use during triage to identify 2+ existing issues that are similar and surface them as potential duplicates.
Implement a GitHub issue in this repository by applying the local shared `implement-specs` workflow with Oz-specific issue, spec-context, and summary-file handling. Use when issue details are provided in the prompt and the agent should produce the repository diff and a concise implementation summary, without creating commits or pull requests itself unless the prompt explicitly asks for it.
Review a pull request diff and write structured feedback to review.json for the workflow to publish. Use when reviewing a checked-out PR from local artifacts like pr_diff.txt and pr_description.md and producing machine-readable review output instead of posting directly to GitHub.
Review a spec/plan pull request diff and write structured feedback to review.json for the workflow to publish. Use when reviewing a PR that only modifies files under specs/ and producing machine-readable review output instead of posting directly to GitHub.

Use this skill only when spec_context.md exists during PR review.
Determine whether the implementation in the checked-out PR materially matches the approved spec context. This is a supplement to the normal code review, not a separate output.
spec_context.md contains the spec context to compare against. It may include both product spec content (intended behavior, acceptance criteria) and tech spec content (implementation details, file changes).pr_diff.txt contains the annotated diff for the PR.pr_description.md may contain additional scope or rationale.spec_context.md and extract the concrete commitments it makes:
pr_diff.txt and the checked-out files.review.json.spec_context.md.
