Memtrace Code Review

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

1. If the user gives a GitHub PR URL and asks to inspect or review it, call review_github_pr with post: false.
2. If the user explicitly asks to publish, post comments, or complete the PR review, call review_github_pr with post: true.
3. Use graphMode: "strict" by default. Use graphMode: "off" only when the user asks to benchmark non-graph behavior or the local graph is unavailable.
4. Default to minSeverity: "high" and maxComments: 5 when posting. For previews, maxComments: 10 is acceptable.
5. Pass repoRoot when the PR checkout is not the current working directory. Pass repoId when the indexed repository id is known.

Full parameter spec for every Memtrace tool: references/mcp-parameters.md (bundled at the memtrace-skills plugin root).

Example User Prompts

• "Review this PR with Memtrace: https://github.com/OWNER/REPO/pull/123"
• "Use Memtrace to review this pull request and post the findings: https://github.com/OWNER/REPO/pull/123"
• "Create the PR, then run Memtrace code review and publish the review comments."

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.
• After posting comments (post: true), record the PR URL and the posted comment IDs in the session output as the audit trail.
• 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 . from the actual repo root. If the open folder is a parent containing multiple independent repos, do not index the parent unless the user explicitly wants a shared workspace.
