Foundations: the packs that run Corey itself

These packs are about Corey rather than your business: how it plans, builds, checks and ships work, how to keep it running on a machine you own, and how to build and improve the MCP servers and apps it is made of. You rarely ask for them by name. They are why a job gets checked before it is called done, and why the scheduled work still runs when you close the laptop.

How the work gets done

The AI SDLCDiscuss, Plan, Execute, Verify, Ship

Reference · 7 files · 2 sources · researched 09/09/2026 · review by 09/03/2027

What it covers

  • The loop - the five steps, the artefact each ends in, and what "done" means at each.
  • Acceptance criteria - criteria that can fail, and the one test that tells you.
  • Blind verification - why the verifier is denied the plan, and what to do when blind verification is impossible.
  • What a check proves - three ways a green check proves nothing, each of which costs a day.
  • Gates and escalation - pre-flight, revision, escalation, abort, named before the work rather than improvised after it.
  • Orchestration - the orchestrator routes and does not execute, and the contract every dispatched agent owes.
  • Context budget - why quality degrades before any warning fires, and when to checkpoint.

What Corey can do with it

Corey reads it whenever a job touches The AI SDLC, whichever skill is running.

Try asking

  • Talk me through the loop for The AI SDLC, and flag anything that changes often.
  • What do I need to get right about acceptance criteria before I start?

What it will not do

  • Do anything public, costly or irreversible without your yes.

Always-on Macrunning Corey's scheduled work on a machine you own

Reference · 12 files · 5 sources · researched 04/10/2026 · review by 04/04/2027

What it covers

  • Choosing a host - the three tiers, when a Mac beats the cloud, laptop or desktop, how much memory, and using an existing laptop as an interim host.
  • Setup playbook - the build, in order, with the check that proves each step. Start here.
  • Power and sleep - sleep, Low Power Mode, the battery charge limit, the lid, and starting again after a power cut.
  • Login session and restarts - what has to stay running (not a terminal), FileVault against auto-login, and the restart plan.
  • Scheduling with launchd - LaunchAgents over cron, the bare PATH that breaks every job, the wrapper every job should go through, and catch-up after sleep.
  • Claude on a host - signing Claude Code in for unattended use, the desktop app as the bridge, and why an exit code is not an outcome.
  • Remote access - the Claude app bridge first, keeping it alive, then NordVPN Meshnet (free) as the private device network, with the alternatives, Remote Login and the firewall.
  • Monitoring - the off-box dead-man, the host heartbeat, outcome alerts, and what to log while you decide on hardware.
  • And 3 more topics.

What Corey can do with it

Corey reads it whenever a job touches Always-on Mac, whichever skill is running.

Try asking

  • Talk me through choosing a host for Always-on Mac, and flag anything that changes often.
  • What do I need to get right about setup playbook before I start?

What it will not do

  • Quote a price, limit or threshold from memory. Figures that move are kept in a dated ledger and re-checked against the primary source first.
  • Do anything public, costly or irreversible without your yes.

MCP servers and apps

MCP serversbuilding and operating one

Reference · 11 files · 2 sources · researched 10/09/2026 · review by 10/03/2027

What it covers

  • Server shape - tools, resources and prompts, what each is for, and how to choose. The choice is a routing decision, not a taste one.
  • Tool design - names, schemas, titles, annotations, and the fact that the description is the routing surface. Includes the two name rules the SDK will not enforce for you.
  • Transports - stdio against streamable HTTP, session-bearing against stateless, and exactly what a per-request server forbids.
  • Auth at the boundary - where authentication belongs, why every gate fails closed, and the trap that the listing is a separate seam from the call.
  • Listing and visibility - tools/list is the per-request seam. Hiding is not a permission, and hiding the wrong tool is silent and total.
  • Errors and refusals - a refusal must carry the next action. One wording per condition, no stack traces, and why this is a large share of what a reviewer sees.
  • Testing a server - in-process, over stdio, and over the wire; and what a local pass does not prove.
  • Deployment - the Host and Origin allowlist that 421s every proxied request when you get it wrong, plus readiness and the deploy gate.
  • And 2 more topics.

What Corey can do with it

  • Mcp app builder - Take an idea to a shipped MCP App - interactive HTML a server serves as a ui:// resource and a host renders inside the conversation. Decides whether it earns a UI at all, then stamps, builds and hands off to verification.
  • Mcp app verify - Prove a built MCP App actually works - static conformance, a protocol handshake against the reference host, and a rendered check in a real client - and emit a scorecard rather than an opinion.
  • Mcp lifecycle - Build an MCP server or MCP App end to end so it ships instrumented, eval-tested and ready for the weekly review, or audit an existing one against that bar.
  • Mcp weekly review - Weekly improvement pass across every MCP server the owner runs - reads usage signals, gaps and feedback, measures last week's changes, researches the top findings, and opens draft PRs and issues to add, rewrite, remove or research tools and knowledge files.

Try asking

  • Build an MCP App
  • Verify the MCP App
  • Build an MCP

What it will not do

  • Quote a price, limit or threshold from memory. Figures that move are kept in a dated ledger and re-checked against the primary source first.
  • Do anything public, costly or irreversible without your yes.

MCP Appsinteractive UI for MCP servers

Reference · 13 files · 2 sources · researched 04/09/2026 · review by 04/03/2027

What it covers

  • Protocol and resource contract - the extension id, the ui:// scheme, the MIME type, capability negotiation, and why the text fallback is mandatory rather than polite.
  • Meta fields - the whole _meta.ui surface, and the thing everyone gets wrong: which _meta object each field belongs to.
  • Jsonrpc surface - every ui/* request and notification in both directions, with what each is actually for.
  • App lifecycle - the App class, the handlers-before-connect rule, teardown, and the sandbox proxy.
  • Host context and theming - the CSS-variable contract, theme, fonts, safe areas, display modes, and how to look native in a host you cannot see.
  • Security csp and auth - the deny-by-default CSP model, CORS and stable origins, authorization at the HTTP boundary, step-up auth, and four questions the spec does not answer.
  • Patterns - app-only tools, polling, chunked reads, streaming partial input, model-context updates, view state, and pausing offscreen work.
  • Serverless deployment - the one nobody else documents. Why the official examples cannot run on a serverless runtime, and what to do instead.
  • And 4 more topics.

Try asking

  • Build an MCP App

What it will not do

  • Never branch on getUiCapability(). It cannot work on a server that builds a fresh instance per request, and it fails with no error at all.
  • Quote a price, limit or threshold from memory. Figures that move are kept in a dated ledger and re-checked against the primary source first.
  • Do anything public, costly or irreversible without your yes.

The running corey skills

Skills are the step-by-step jobs that lean on these packs. You start one by asking for the job in plain English.

Questions

5 knowledge packs, 56 files in all: how the work gets done (The AI SDLC, Always-on Mac); mcp servers and apps (MCP servers, MCP Apps, MCP operations).
No. Ask for the job and Corey reads the packs it touches. You can name one to be sure, for example "use your The AI SDLC pack for this".
Every pack shows the date it was researched and the date it must be reviewed by (the earliest here is 29/12/2026). Figures that move fast are kept in a dated changes ledger and re-checked against the primary source before Corey quotes them.
No. The packs are reference material. Corey uses them to do the work and explain it, and anything public, costly or irreversible waits for your approval.

Where next

Corey is free for individuals and takes about two minutes to add to Claude.
