Spec-Driven Development (SDD) methodology for AI software factories — where structured specifications are the input, AI agents generate the code, and quality gates enforce correctness at each pipeline phase. Use when designing a spec → review → decompose → implement → verify pipeline that any AI coding tool (Claude Code, Cursor, Hermes Agent, Devin, OpenHands) can follow.
Query your Jellyfin media server from the terminal — recently added media, search, item details, next-up episodes, library browsing, server info, and stats. Use when the user asks about Jellyfin, media server, movies, TV shows, next episodes, or their media library.
Multi-agent structured debate system. Spawn a panel of expert agents to debate any question, with convergence-aware iteration and typed synthesis output. Run via `agent-council` CLI. Compatible with any AI agent harness that supports agentskills.io skills (Claude Code, Cursor, Hermes Agent, OpenHands, etc.).
Reference for the Agent Skills open format — the directory structure, SKILL.md frontmatter schema, naming conventions, progressive disclosure model, and best practices for creating skills. Use this whenever creating, reviewing, or editing skills in this repository to ensure they follow the standard spec.
Verify work against explicit criteria using evidence, reproducible checks, and clear pass, conditional, or blocked verdicts. Use before declaring an artifact, implementation, or claim complete.
Manage Linear teams, projects, cycles, issues, comments, workflow state, and documents from a terminal through Linear's public GraphQL API. Use when a user asks to list, search, inspect, create, update, move, or comment on Linear work, or to find Linear documents. Do not use to embed a live agent inside Linear or to build an MCP integration.

A comprehensive methodology for designing, operating, and improving reliable production systems. Rooted in Google SRE principles and extended with modern practices for incident command, observability engineering, error budget governance, and operational excellence.
| Trigger | What It Means |
|---|---|
| "Design reliability into this system" | SLO/SLI framework, error budget policy, resilience architecture |
| "Run an incident postmortem" | Blameless postmortem with timeline, 5 Whys, action tracking |
| "Improve our on-call" | Rotation design, alert tuning, toil reduction, escalation policy |
| "Build observability" | The Four Golden Signals, dashboard design, alert rule patterns |
| "Do a reliability review" | Architecture review against SRE principles, risk assessment |
| "I need an incident commander" | Incident command framework, role cards, communication templates |
| "Automate this operational task" | Toil assessment, automation decision tree, runbook pattern |
