• data-model

  Data modeling and schema design for Apache Cassandra. Use when designing tables, choosing partition keys, modeling time-series data, or reviewing existing schemas.

• diagnose

  Systematic troubleshooting for Apache Cassandra clusters. Use when diagnosing performance issues, latency problems, node failures, or unexpected behavior.

  plugins/cassandra-expert/skills/diagnose/SKILL.md on GitHub (opens in a new tab)

• optimize

  Performance optimization for Apache Cassandra clusters. Use when tuning configuration, improving throughput, reducing latency, optimizing resource usage, or configuring vnodes/num_tokens.

  plugins/cassandra-expert/skills/optimize/SKILL.md on GitHub (opens in a new tab)

• token-skew

  Analyze token distribution and data ownership skew across Cassandra nodes and racks. Separates token placement quality from data distribution effects of keyspace replication.

  plugins/cassandra-expert/skills/token-skew/SKILL.md on GitHub (opens in a new tab)

• training

  Interactive Cassandra training with guided curriculum. Covers fundamentals through advanced topics with hands-on CQL and code examples. Use when a user wants to learn Cassandra, not just get answers.

  plugins/cassandra-expert/skills/training/SKILL.md on GitHub (opens in a new tab)

• complexity-reduction

  Measure cognitive complexity and duplicate code with PMD (Java) or rust-code-analysis-cli (Rust), then reduce both by pure-move extraction, re-measuring after every step. Runs over a subsystem or over a PR diff. Use this when the user asks to simplify, refactor, clean up, or reduce the complexity of a subsystem, asks "how complex is X", asks to find duplicate code, asks to make code "beautiful",…

• ide-explain

  Render an IDE-style single-page HTML view that explains anything the owner needs to see whole — a code diff, a GitHub issue plus everything linked to it, project docs, or any mix — as a file tree on the left, a code/diff/doc editor top-right, and an explanation pane bottom-right. Deterministic by default (no model tokens spent on markup); a hand-authored manifest mode exists for taught narratives…

• prose-review

  Grade the prose in a patch against prose-style.md and report the findings; apply them with --fix. Covers code comments and javadoc by default, and commit messages, the PR description, or release notes when asked. Use this skill when the user asks to review, audit, grade, clean up, fix, tidy, or restyle comments, javadoc, commit messages, a PR description, or release notes, says "the comments need…

• refactor

  Plan and execute a behavior-preserving structural change, then hold the refactoring contract for the whole run. Use this skill when the user says "refactor this", "clean up this code", "restructure", "extract this", "split this up", "pay down tech debt", or "the tests are fighting me"; when the work is a `type:tech-debt` issue; or at the REFACTOR step of a TDD cycle. It produces a written plan fo…

• tech-debt

  Audit the codebase for structural improvement opportunities — SOLID/composability, code duplication, and unnecessary layering — using a parallel team of review agents. Ranks the 10 most impactful findings, excludes anything already in the open backlog, and walks the owner through them one at a time with full context; the owner decides per item whether to file it as a GitHub issue. Not tied to any…

• walkthrough

  Render a diagram-first, ordered-step HTML presentation that teaches how something works — or presents a technical-debt review, an areas-for-improvement pass, a set of recommendations, or a performance analysis. You investigate the code and author every word; a deterministic renderer turns your manifest into one self-contained page (vertical scroll by default, one button away from slide-by-slide).…

• create-kit

  Create a new easy-db-lab kit (kit.yaml + K8s manifests, metrics, dashboards, docs) for any database or workload. Detects internal (the easy-db-lab repo) vs external (your own project) mode, researches the workload, grounds the work in a per-kit TODO.md, drafts for review, and writes deliverable files only on explicit approval. Use when adding a new database or workload kit to easy-db-lab or to yo…

• explore

  Guided interactive mode for easy-db-lab — walks through provisioning if needed, then helps you run tests, stress workloads, and explore Cassandra, ClickHouse, Spark, and OpenSearch. The end-to-end starting point for a new lab session.

  plugins/easy-db-lab/skills/explore/SKILL.md on GitHub (opens in a new tab)

• plan

  Helps the user design a lab workflow by asking questions, working through steps together, and writing the result to a plan.md file. Use when planning a new lab run, benchmarking test, or database experiment.

  plugins/easy-db-lab/skills/plan/SKILL.md on GitHub (opens in a new tab)

• run

  Executes a plan step by step in an explicit cluster workspace, confirming each step with the user and updating journal.md as work proceeds. Use when the user says "run a plan", "execute the plan", "run this plan.md", "start/resume the lab run", or otherwise asks to run, execute, or resume a lab plan, benchmark, or database experiment.

• activate

  Activate a groomed GitHub issue for development — claim it, review it with the owner (scope/acceptance-criteria freshness + backlog overlap, issue-specific questions, skippable via owner-instructions), run architect + domain-expert design concurrently then stress-test the result with design-critic, stop for the owner's design choice before generating anything, then OpenSpec explore+propose and st…

• address

  Address the owner's GitHub review comments on an issue's PR — pull the comments, fix them in the issue's worktree, push, and reply per review thread. Fourth stage of the flow delivery workflow (see docs/workflow.md). Owner-invoked when they return after reviewing; never polls.

• adopt-tiering

  One-time migration that splits a repo's existing test suite into a fast unit tier and a slow integration tier — for a repo whose own spec-flow/TESTING.md policy chooses that split, not an assumption the pipeline makes. Classify tests by evidence (container/I-O/timing) and let the compiler + test timings arbitrate, physically separate them (Gradle source set + classpath scoping, or Rust src/ vs te…

• archive

  Check the buildup of un-archived OpenSpec changes waiting on the default branch (one per merged-and-finalized issue) against a threshold (default 5, overridable), and — once confirmed with the owner — spawn a dedicated background worker to sync and archive them all in one pass and land one PR. Owner-invoked or offered by project-manager when it notices the buildup; never automatic. Part of the fl…

• board

  Report status across all in-flight delivery pipelines — every issue by lifecycle label with its priority, stage, live issue-manager session, and PR state — and highlight what's next, what's blocked on the owner, and what's stalled. Use when the owner asks 'where do things stand' or 'what should I work on'. Part of the flow delivery workflow (see docs/workflow.md).

  plugins/spec-flow/skills/board/SKILL.md on GitHub (opens in a new tab)

• finalize

  Finalize a merged issue — close the GitHub issue, remove its lifecycle/coordination labels, close and clean any issue recorded to close with it, and remove the issue's git worktree. Final stage of the flow delivery workflow (see docs/workflow.md). Runs once the FEATURE PR has merged — by the owner's squash-merge by default, or by `implement` itself if the `merge-on-green` label was set or this ru…

• groom

  Turn a rough idea into a scoped, labeled GitHub issue ready for the delivery pipeline. Use when the owner wants to capture a todo, feature, or bug as a real backlog item with scope, acceptance criteria, and a priority. Refines the idea over as many rounds as it takes — each round a fresh `product-manager` that has read the code, whose questions are asked one per message, each with a stated recomm…
