What it installs

Skills (14)

  • ask

    Answer grounded questions about the codebase (onboarding / Q&A) using the reviewer RAG + code graph. Use when the user asks how the code works, where something lives, or to explain a subsystem ("where is auth", "how does X work", "explain the indexing flow", "как устроено…", "где у нас…", "объясни к

  • configure-review

    Use when configuring or changing a repository's tracked branches, layered review policy, ignored tracked paths, retrieval limits, summary depth, or non-secret task-board metadata.

  • create-task

    Create a task on a configured board with canonical server-side structure. Use when the user asks to file or create a task on the board.

  • decompose-task

    Use when a configured board task needs decomposition into native child tasks.

  • finish-task

    After a task's PR is created, offer to close the task on the configured board and reindex it. Use when the user says a PR is up or asks to close or finish a task.

  • maintainability-review

    Review code changes only for maintainability risks: unnecessary complexity, poor readability, duplication, weak separation of concerns, and misalignment with repository conventions. Use when the user explicitly asks for maintainability review, code quality review, clean code review, complexity revie

  • performance-review

    Review code changes only for performance and efficiency risks (N+1 queries, repeated work, bad asymptotics, missing batching/caching, blocking I/O, memory growth). Use when the user explicitly asks for a performance review of a diff/PR.

  • pr-walkthrough

    Build a human-facing reading guide for a GitHub pull request (where to start, what each file changes, what it impacts) using the reviewer PR session + code graph. Use when the user asks to walk a human reviewer through a PR ("PR walkthrough", "гид по PR", "как читать этот PR", "проведи по PR"). NOT

  • report-bug

    Report a defect of reviewer or its plugin as an anonymized GitHub issue in mimfort/rag_for_git, after explicit user approval. Use when a reviewer tool breaks its own contract, a skill prescribes an impossible step, a stated invariant fails, or the user asks to report a reviewer bug.

  • review-pr

    Review a GitHub pull request with the RAG + code-graph pipeline (reviewer MCP server). Use when the user asks to review a PR ("review PR 123", "заревьюй PR", a PR URL). Requires ParadeDB/Neo4j running and a built base index.

  • solve-task

    Gather disciplined context for solving a task, then hand off to development. Use when the user asks to solve/implement a task ("solve PRI-4", "rag-reviewer:solve-task <key or description>", "реши задачу X"). Reads a keyed task from the reviewer store, pulls related/similar tasks and relevant code, d

  • summarize-subsystems

    Precompute concise per-subsystem summaries (GraphRAG community summaries) over the base code index, so ask / PR-walkthrough get a cheap high-level prior. Use when the user asks to build/refresh subsystem summaries ("просуммируй подсистемы", "построй обзоры модулей", "summarize subsystems"). Requires

  • sync-codebase

    Build or update the reviewer base index (vector store + code graph) from a local repo clone. Use when the user asks to "index the codebase", "build the index", "sync the code", "rebuild the graph", "просиндексируй код", "построй индекс".

  • sync-tasks

    Warm the task graph and vector store by synchronizing a configured task board through the reviewer MCP server. Use when the user asks to sync or index board tasks.

    runs: /bin/bash -lc uvx --from rag-reviewer reviewer-mcp
