Generate a test suite of natural-language → SQL pairs that becomes the quality benchmark for a nao agent, then run it via `nao test`. Use when the user wants to start measuring agent reliability, extend an existing test suite, or add tests for new metrics. Tests are the only honest answer to "is the context working?". Do not use for writing rules (write-context-rules) or diagnosing failures (audit-context).
Migrates databases between providers (Postgres, MySQL, Supabase, PlanetScale, MongoDB). Reads source schema, generates migration scripts, handles data type mapping, foreign keys, indexes, triggers, stored procedures. Validates migration with row counts and checksums. Generates migration-plan.md with step-by-step execution guide, rollback procedures, estimated downtime.
Expert FastAPI developer specializing in production-ready async REST APIs with Pydantic v2, SQLAlchemy 2.0, OAuth2/JWT authentication, and comprehensive security. Deep expertise in dependency injection, background tasks, async database operations, input validation, and OWASP security best practices. Use when building high-performance Python web APIs, implementing authentication systems, or securing API endpoints.
Fibonacci retracement and extension trading for NSE/BSE equities. Covers entry zones using retracement levels, profit targets using extension levels, and confluence zone identification. Use when the user asks: "fib levels for [stock]", "Fibonacci retracement", "fib extensions", "where to enter on pullback", "what are the retracement levels", "golden ratio level", "Fibonacci targets", or any question about Fibonacci-based trading levels for Indian equities.
Workflow required before generating, writing, or updating BAT (Blackbox API Testing) tests for a Mule app. Call use_skill as your FIRST action — before reading or writing any .dwl file — whenever the user asks to create, generate, add, write, refresh, extend, or fix BAT tests, a BAT suite, BDD API tests, black-box API tests, or Anypoint API Functional Monitoring tests for a deployed Mule HTTP API. Do not read the app source, open the existing suite, or author any .dwl yourself and attempt the task in one turn — even a targeted single-test change like 'add a 401 test' or 'fix the orders happy-path test' requires loading this skill first. Covers generating a suite from app source (OpenAPI + Mule XML), extending an existing hand-written BAT baseline, and running the suite against the live endpoint. Not for MUnit (build-time, in-process, XML) — use the Mule developer workflow for that. When you call this skill, it must be the only tool call in that response.
Expert blueprint for TPS/hybrid shooters: soft-lock aim assist, cover validation rays, SpringArm TPS camera, and genre routing to FPS sibling for viewmodel/hitscan feel. Use for third-person/cover shooters and hybrids. Keywords: TPS, soft_lock, cover, SpringArm3D, hybrid shooter, aim assist — not FPS-only movement
Expert blueprint for First-Person Shooters: fps_camera_look, fps_movement_logic, hitscan_weapon_query, weapon_bobbing_system, procedural recoil, and FPS NEVER rules. Shared TPS/cover theory links to godot-genre-shooter. Keywords: FPS, movement physics, weapon bobbing, camera sway, hitscan, viewmodel, air control.
Expert-level Grafana dashboards, visualization, data sources, alerting, and production operations. Use when the user mentions dashboards, visualization, monitoring, observability, or alerting, or when the task involves Grafana Architecture, Installation on Kubernetes, Data Sources, or Dashboard JSON.
Write and revise queries with the published HelixDB Go SDK v0.3.1. Use for normal functions returning `helix.Request`, `ReadQuery`/`WriteQuery`, inline params, traversal builders, projections, indexes, vector and BM25 search with traversal-scoped prefiltering, and server execution through `Client.Exec`. The module remains `github.com/helixdb/helix-db/sdks/go` without a `/v3` suffix; standard installs do not ship embedded or native-graph bindings. Stored routes and query bundles are not supported. When the target is Helix Cloud, always use helix-mcp first
Retrieve year-over-year growth in income statement items, including Revenue, Gross Profit, Operating Income, Net Income, and EPS Diluted. Use when analyzing company financial growth trends, comparing fiscal year performance, or identifying profitability inflection points
Manage Jira issues via Atlassian MCP — search, create, update, transition status, and handle sprint tasks. Auto-detects workspace configuration. Use when user says "create a Jira ticket", "update my sprint", "check Jira status", "transition this issue", "search Jira", or "move ticket to done". Do NOT use for Confluence pages (use confluence-assistant).

Use when migrating pages to Edge Delivery Services, auditing a site, or extracting a page's icons, metadata, or other assets
Read, summarize, and critically analyze an academic paper from a PDF, official HTML page, URL, or pasted full text. Use for requests such as "read this paper", "快速看懂", "精读论文", "analyze this paper", "paper summary", or strict paper critique. Produces evidence-traceable Markdown or a portable interactive HTML report at one complete, concise close-reading depth, with read-only inspection of authoritative source code when available and no reproduction run.
Reference for the Pinecone MCP server tools. Documents all available tools—list-indexes, describe-index, describe-index-stats, create-index-for-model, upsert-records, search-records, cascading-search, and rerank-documents. Use when an agent needs to understand which Pinecone MCP tools are available, how to use them, or what parameters they accept.
Use this skill for planning, testing, and safely executing PostgreSQL schema migrations — especially when working with production data or shared databases. Trigger when user asks to: Test a schema migration before applying it to production; add, remove, or rename columns safely on a live table; change a column's data type without downtime; add or drop indexes, constraints, or foreign keys on large tables; understand which ALTER TABLE operations lock the table; roll back a failed migration; plan a zero-downtime migration strategy; or fork a database to test a migration safely. Keywords: migration, schema change, ALTER TABLE, add column, drop column, rename column, change type, zero downtime, lock, AccessExclusiveLock, concurrent index, forking, rollback, backfill, deploy.

An expert in writing intelligent tender documents, covering tenders for engineering consulting, architectural design, municipal projects, IT, software development, and goods and services procurement, with particular depth in construction projects. Parses tender documents, extracts scoring criteria and disqualification clauses, develops bidding strategies, writes technical and commercial proposals, and reviews item-by-item responses, compliance, and disqualification risks. Use when users mention bids, bidding, tenders, technical proposals, commercial proposals, scoring criteria extraction, disqualification risks, item-by-item responses, deviation tables, government procurement, tender, or RFP response. Not for general business writing, marketing copy, academic papers, or documents unrelated to bidding.
This skill should be used when the user asks to "write a pipeline", "add caching", "make this build faster", "show test failures in the build page", "add annotations", "only run tests when code changes", "set up dynamic pipelines", "add retry", "parallel steps", "matrix build", "add plugins", or "work with artifacts in pipeline YAML". Also use when the user mentions .buildkite/ directory, pipeline.yml, buildkite-agent pipeline upload, step types (command, wait, block, trigger, group, input), if_changed, notify, concurrency, dynamic pipeline quotas, pipeline upload limits, or asks about Buildkite CI configuration.

Handles the Chrome 137+ restriction on loading unpacked extensions and the side panel user-gesture requirement. Use when testing, automating, or validating a Chrome extension's UI
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
