Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.
Implement a piece of work based on a spec or set of tickets.
Reconcile the OKF knowledge bundle (knowledge/) with what a completed code change built, over that change's diff. Use once a change has finished landing โ the build closeout, just before committing โ or when the user asks to reconcile knowledge against code.
Configure this repo for the engineering skills โ set up its issue tracker, triage label vocabulary, and domain doc layout. Run once before first use of the other engineering skills.
Turn the current conversation into a spec and save it to the OKF knowledge bundle โ no interview, just synthesis of what you've already discussed.
Break a plan, spec, or the current conversation into a set of tracer-bullet tickets, each declaring its blocking edges, published to the configured tracker โ edges as text in a local file, or native blocking links on a real tracker.

You don't remember every skill, so ask.
A flow is a path through the skills. Most paths run along one main flow, and two on-ramps merge onto it. Everything else is standalone, or a vocabulary layer that runs underneath.
The route most work travels. You have an idea and want it built.
/grill โ sharpen the idea by interview. Start here when you have a codebase: it's stateful, retaining what it learns in the OKF knowledge bundle (knowledge/ โ glossary and ADRs). (No codebase? Use /grill-plain โ see Standalone. Both run the same /grilling primitive; grill is the one that leaves a paper trail.)
Branch โ can you settle every question in conversation? If a question needs a runnable answer (state, business logic, a UI you have to see), detour through a prototype, bridged by /handoff in both directions (see Crossing sessions):
/handoff out, then open a fresh session against that file,/prototype to answer the question with throwaway code,/handoff back what you learned, and reference it from the original idea thread.Branch โ is this a multi-session build?
/to-spec (turn the thread into a spec), then /to-tickets to split it into tracer-bullet tickets, each declaring its blocking edges. On a local tracker that's an ordered tickets.md you work by hand; on a real tracker the edges become native blocking links, so any ticket whose blockers are done can be grabbed โ kick off /implement per ticket, clearing context between each one./implement right here, in the same context window.Either way, /implement builds each ticket by driving /tdd internally โ one red-green slice at a time โ then closes out by running /vet (a two-axis review โ Standards + Spec โ of the diff) and /reconcile (which brings the OKF bundle back into agreement with what was built), before committing code and knowledge together. Reach for /tdd on its own when you just want to build a concrete behaviour test-first without a full spec, and /vet on its own whenever you want to review a branch or PR against a fixed point.
Keep steps 1โ3 in one unbroken context window โ don't compact or clear until after /to-tickets โ so the grilling, spec, and tickets all build on the same thinking. Each /implement then starts fresh, working from the ticket.
The limit on this is the smart zone: the window (~120k tokens on state-of-the-art models) within which the model still reasons sharply. If a session approaches it before /to-tickets, don't push on degraded โ /handoff and continue in a fresh thread.
A starting situation that generates work, then merges onto the main flow.
Bugs and requests piling up โ /triage. It moves issues through triage roles and produces agent-ready issues, which /implement later picks up.
Triage is only for issues you didn't create โ bug reports, incoming feature requests, anything that arrives raw. Tickets that /to-tickets produced are already agent-ready, so don't triage them.
Something's broken โ /debug. For the hard ones: the bug that resists a first glance, the intermittent flake, the regression that crept in between two known-good states. It refuses to theorise until it has a tight feedback loop โ one command that already goes red on this bug โ then fixes with a regression test. Its post-mortem hands off to /improve-arch when the real finding is that there's no good seam to lock the bug down.
A huge, foggy effort โ a greenfield project or a huge feature build, too big for one session โ /wayfinder. When the way from here to the destination isn't visible yet, it charts a shared map of investigation tickets on the issue tracker and resolves them one at a time โ producing decisions, not deliverables โ until the fog is pushed back and the way is clear. Then it merges onto the main flow at /to-spec (or, if the effort turned out small enough, straight to /implement). Where /grill sharpens an idea you can hold in one session, wayfinder is for the idea you can't.
Not feature work โ upkeep.
/improve-arch โ run whenever you have a spare moment to keep the codebase good for agents to operate in. It surfaces deepening opportunities; picking one generates an idea you can take into the main flow at /grill. It's the survey that finds the candidates; /codebase-design (below) is the bench you design the chosen one on.Two model-invoked references that run beneath the other skills โ each the single source of truth for its vocabulary. Reach for them directly when the words, not the process, are the problem; or let the skills above pull them in.
/domain-modeling โ sharpen the project's domain language: challenge a fuzzy term, resolve an overloaded word ("account" doing three jobs), record a hard-to-reverse decision as an ADR. It's the active discipline /grill drives to keep the knowledge bundle's glossary (knowledge/glossary/) clean. It writes the bundle on the design side; /reconcile is its build-side mirror โ after /implement (or a bug fix, or a hand refactor) lands code, it re-syncs the bundle to what was actually built so knowledge doesn't drift between sessions./codebase-design โ the deep-module vocabulary (module, interface, depth, seam, adapter, leverage, locality) for designing a module's shape: a lot of behaviour behind a small interface at a clean seam. /tdd and /improve-arch both speak it./handoff โ when a thread is full or you need to branch off (e.g. into a /prototype session), this compacts the conversation into a markdown file. You don't continue in place โ you open a new session and reference that file to carry the context across. It's the bridge between context windows, in either direction. Use it when you want a fresh session but need the current conversation preserved./compact (built-in) โ stay in the same conversation, letting the earlier turns be summarized. Use it at intentional breaks between phases, when you don't mind losing the verbatim history. Don't compact mid-phase โ the agent can lose its way. /handoff forks; /compact continues.Off the main flow entirely.
/grill-plain โ the same relentless interview as /grill, but for when you have no codebase. Stateless: it saves nothing locally, builds no knowledge bundle. Reach for it to sharpen any plan or design that doesn't live in a repo./prototype โ a small, throwaway program that answers one design question: does this state model feel right, or what should this UI look like. Throwaway from day one โ keep the answer, delete the code. It's the detour in step 2 of the main flow, but reach for it any time a design question is hard to settle on paper./research โ delegate reading legwork to a background agent: it investigates a question against primary sources, then leaves a cited Markdown file in the repo. Keep working while it reads. The file it produces is something to take into the main flow at /grill โ research feeds the thinking, it doesn't replace it./teach โ learn a concept over multiple sessions, using the current directory as a stateful workspace./write-skill โ reference for writing and editing skills well./setup-okf-matt-skills โ run before your first engineering flow to configure the issue tracker, triage labels, and doc layout the other skills assume. Custom issue trackers also work.
