| name | memtrace-code-review |
| description | Always use when the user asks to review a GitHub pull request, run Memtrace code review, post Memtrace review comments, create a PR with a review step, or publish local graph-backed review findings to GitHub. Prefer the review_github_pr MCP tool over manual diff inspection. |
Overview
Use Memtrace's local-first PR review workflow. The agent should call the review_github_pr MCP tool so review runs against the developer's local indexed graph, AST detectors, YAML rule pack, and review policy. GitHub is used for PR context and optional comment publication; source code analysis stays local.
Default Flow
- If the user gives a GitHub PR URL and asks to inspect or review it, call
review_github_pr with post: false.
- If the user explicitly asks to publish, post comments, or complete the PR review, call
review_github_pr with post: true.
- Use
graphMode: "strict" by default. Use graphMode: "off" only when the user asks to benchmark non-graph behavior or the local graph is unavailable.
- Default to
minSeverity: "high" and maxComments: 5 when posting. For previews, maxComments: 10 is acceptable.
- Pass
repoRoot when the PR checkout is not the current working directory. Pass repoId when the indexed repository id is known.
Guardrails
- Do not start with generic grep, rg, or manual diff review when
review_github_pr is available.
- Do not post comments unless the user explicitly requested publication.
- Do not create benchmark-specific or PR-specific findings. The review must come from general Memtrace detectors, graph evidence, and policy ranking.
- If the tool reports missing auth, tell the user to run
memtrace auth login.
- If the tool reports missing GitHub App installation, tell the user to install Memtrace Code Reviewer on that repository.
- If the tool reports missing local graph context, tell the user to run
memtrace index . at the workspace root.
Output
For previews, summarize:
- PR URL and repository
- Graph state
- Number of candidate comments
- File, line, severity, and message for each finding
For posted reviews, report the PR URL and number of comments posted.
