Profile GKG queries against ClickHouse with the query-profiler CLI. For optimizing query performance, comparing query plans, investigating slow queries, or checking ClickHouse resource usage.

Autonomous fixer for documentation PRs. Triggered by @claude comments on PRs targeting dev. Reads the writer's request and the doc-pr review comment, then applies fixes and commits. Use this skill whenever a writer tags @claude on a documentation PR — not for interactive help (use doc-help for that), but for autonomous, single-shot fixes in CI.

Work with Obsidian vaults (plain Markdown notes) and automate via obsidian-cli.

Performs deep analysis of a specific Amplitude chart to explain trends, anomalies, and likely drivers. Use when a metric looks unusual, investigating a spike or drop, or understanding the "why" behind numbers.

Analyze a business, product, or feature using Hamilton Helmer's 7 Powers framework to assess competitive advantage and strategic durability. Use when the user asks about competitive moats, strategic positioning, power analysis, defensibility, competitive advantage, or "7 Powers".

Triage AEM Workflow issues on AEM 6.5 LTS and AMS by classifying symptoms, gathering the right logs and metrics, and mapping to runbooks or Splunk searches. Use when the user asks for workflow activity/errors on a 6.5 host, needs to classify a Jira ticket, or wants to know what to collect for workflow debugging.

Buy and sell NFTs on OpenSea's Seaport marketplace. Fulfill listings, accept offers, create new orders, cross-chain purchases, and sweep multiple listings. Requires wallet signing; for read-only queries use opensea-api instead.

Convert Docker Compose files to Coolify templates. Use when creating Coolify services, converting docker-compose.yml for Coolify deployment, working with SERVICE_URL/SERVICE_PASSWORD magic variables, or troubleshooting Coolify compose errors.

Manage Jira issues and Confluence wiki pages in Atlassian Cloud. Use when: (1) searching/creating/updating Jira issues with JQL, (2) searching/reading/creating Confluence pages with CQL, (3) managing Jira workflows, transitions, and comments, (4) browsing Confluence spaces and page hierarchies. Supports OAuth 2.1 via MCP server (recommended) or API token authentication (fallback).

This skill should be used when the user says "review infra change", "infrastructure review", "review infrastructure", "infra quality review", "arn infra review", "check infra change", "review infrastructure change", "infra change review", "quality check infrastructure", "arn-infra-review-change", "post-deployment review", or wants to perform a comprehensive post-execution quality review of completed infrastructure changes, producing a structured review report with a PASS/WARN/NEEDS_FIXES verdict.

This skill should be used when the user says "batch simplify", "cross-feature simplify", "batch simplification", "simplify all features", "cross-feature quality pass", "batch code cleanup", "consolidate across features", "deduplicate across features", "cleanup after batch merge", "cross-feature deduplication", "arness batch simplify", "arn-code-batch-simplify", "simplify merged features", "post-merge simplify", "find cross-feature duplication", or wants to run a post-merge quality pass that finds duplication and consolidation opportunities across independently implemented features. This requires merged features in .arness/plans/ — run arn-code-batch-merge first if none are merged.

This skill should be used when the user says "review PR", "review pull request", "check PR comments", "review PR feedback", "review PR 123", "analyze PR comments", "validate PR review", "address PR feedback", "fix PR issues", "what did the reviewer say", "review Bitbucket PR", or wants to validate GitHub or Bitbucket PR review comments, categorize findings, and optionally connect back into the Arness pipeline for fixes. Do NOT use this for creating PRs (use arn-code-ship) or reviewing implementation quality (use arn-code-review-implementation).

This skill should be used when the user says "triage infra request", "infra triage", "arn infra triage", "process infra issue", "handle infra request", "infrastructure request", "triage infrastructure", "analyze infra issue", "infra request analysis", "process infrastructure request", or wants to process an incoming infrastructure request issue created by Arness Core or manually, analyze its infrastructure implications, and produce a structured implications brief.

This skill should be used when the user says "taskify", "create task list", "create tasks", "convert plan to tasks", "generate tasks from plan", "create tasks from plan", "turn plan into tasks", "arness code taskify", or wants to convert a structured project plan's TASKS.md into an executable Claude Code task list with proper dependency management.

This skill should be used when the user says "save infra plan", "save infrastructure plan", "structure infra plan", "create infra project", "finalize infra plan", "arn infra save plan", "infra save plan", "save change plan", "structure infrastructure plan", "finalize infrastructure plan", "arn-infra-save-plan", or wants to convert a PLAN_PREVIEW_INFRA_*.md into a structured project directory with infrastructure-specific templates, report templates, and progress tracking.

This skill should be used when the user says "document project", "generate docs", "create documentation", "write docs", "arness code document", "arn-code-document-project", "document this feature", "document this fix", or wants to generate developer documentation for a completed feature or bug fix. Reads plan artifacts, spec files, execution reports, and git diff to produce accurate documentation. Do NOT use this for general-purpose documentation — this is specifically for Arness pipeline projects.

This skill should be used when the user says "review implementation", "review the project", "check implementation", "quality review", "validate implementation", "implementation review", or wants a post-execution quality gate to verify that the implementation follows the project's stored code and testing patterns and matches the plan. Reports issues as ERRORS, WARNINGS, INFO with a verdict. Do NOT use this for reviewing PRs (use arn-code-review-pr) or validating plans (use arn-code-review-plan).

This skill should be used when the user says "batch merge", "merge batch", "arness batch merge", "arn-code-batch-merge", "merge all PRs", "merge batch PRs", "merge the batch", "merge implemented features", "batch merge PRs", "merge open PRs", "merge all feature PRs", "combine batch PRs", "land the batch", "land all PRs", or wants to discover open batch implementation PRs, analyze them for conflicts, determine an optimal merge order, and execute merges with user-guided conflict resolution. This skill is typically invoked after arn-code-batch-implement completes and chains to arn-code-batch-simplify upon completion.

This skill should be used when the user says "create issue", "file issue", "arness code issue", "arness code create issue", "arn-code-create-issue", "report bug", "request feature", "add to backlog", "create GitHub issue", "create Jira issue", "file a bug", "submit issue", "log issue", "open issue", or wants to create an issue in the current repository with Arness labels for type and priority. Requires an issue tracker (GitHub or Jira) to be configured. Do NOT use this for picking/browsing existing issues — use /arn-code-pick-issue for that.

This skill should be used when the user asks to "fork", "race claude and codex", "dual implement", "run both models", "compare implementations", "implement with both", "fork it", or wants the same task implemented by both Claude Code and OpenAI Codex in parallel to pick the best result. Also triggered by the /fork command.
