Extensions

Before anything else, check the model this session runs on. These workflows need Opus/Sol level or higher; smaller models follow them unreliably. If this session is below that level, tell the user and recommend switching model before continuing.

Extensions are how an organization gives incident.io's agents its own tools and instructions. There are two kinds: plugins — directories of skills synced from the organization's repositories, which agents load and follow — and connectors — MCP servers whose tools agents can call. references/extensions-product.md explains how the system works; read it before answering questions about it or changing anything.

This skill is the entrypoint. It teaches the system, reads the current state of an estate, and picks the right mechanism for a problem — and it routes every specialised job to the skill that owns it rather than doing it here.

Whatever the task, the first two moves are the same: read the estate, and hear what the user needs. Nothing else — no drafting, no probing of any connected system — starts before both.

Route by the task

• Understand the system — what plugins, skills, and connectors are, how agents use them, what's possible → references/extensions-product.md
• Read the estate, or set it up — what exists today (plugins and their sync state, connections and their health, content), measured against what a ready estate has. One walk serves every starting point, from scratch to a readiness pre-check. → references/estate.md
• Choose the right mechanism — the user describes a problem ("I want these steps run at the start of an investigation", "I want something that diagnoses this error code") and it needs mapping to the feature that solves it: a skill, a runbook, an architecture doc, a connector, or a combination. This picks the mechanism, not a detailed plan of what to build — drafting the content is the owning skill's job. → references/choosing-a-mechanism.md
• Scaffold and register a plugin — create the tree in the team's repository, register it, and verify the first sync. → references/scaffold.md
• Write or improve a skill → load the skill-authoring skill now, before touching any target system — its create job owns the order of work (the user's context first, exploration after), and starting the exploration here skips the gates that make the skill worth writing.
• Write or answer from architecture docs → the architecture skill
• Review the estate's health ("is our setup healthy? what's degraded?") → the doctor skill

Ground rules

• Ground before proposing. Grounding means two things, and target-system exploration is neither: the incident.io estate (references/estate.md — what's registered, connected, and already written; extension_plugin_list is the first call), and the user's intent — what they actually need, in their words. Probing the system a skill will cover is part of authoring, owned by skill-authoring, and comes after the user has confirmed what the skill is for. However inviting a connected tool surface is, exploring it before that conversation is guessing with tools.

• Confirm before creating. Every artefact — a directory, a registration, a doc — is proposed with what it will contain, and created only on a yes.

• Requirements are few; the rest is guidance. The hard requirements are what the platform needs to function:

  • a repository the connected source-control integration can read
  • a registered plugin

  Everything else (architecture docs, runbooks, more skills) is a recommendation: explain why it produces better results, then respect the user's choice. A narrow use case gets a narrow setup, not the full walk's ambitions.

• Speak the user's language, not this skill's. The user hasn't read this file — never cite "the ground rules", a reference filename, or "the estate walk" at them. Say what you're doing plainly ("I'm checking your configuration before we get started") and end a read-only pass with an offer of what you can help with next.

• Connections are created in the dashboard, never here. Connecting a tool to incident.io is an authentication flow. Where a gap is found, link the user to the dashboard's Extensions page and continue with what exists.

• Specialised work goes to the skill that owns it. This skill owns the estate-level picture and the routing; the routes above name the owners.

What this skill is not for

Incident response — this skill configures the machinery agents use, it doesn't investigate incidents.
