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-with-docs sharpens the idea by interview. Start here whenever you are working in a working directory: it's stateful, retaining what it learns in GLOSSARY.md and ADRs. (No working directory? Use /grill-me instead, covered under Standalone. Both run the same /grilling primitive; grill-with-docs is the one that leaves a paper trail, which makes it the better of the two whenever a repo is there to leave it in.)
Branch: 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 (a prototype lives in its own directory, which is exactly what /handoff is for; see Phase boundaries):
/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: 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. Then work the tickets one of three ways:
/implement per ticket, /clearing context between each one. On a local tracker that's one file per ticket under .scratch/<feature>/issues/, worked blockers-first by hand; on a real tracker the edges become native blocking links, so any ticket whose blockers are done can be grabbed. Each ticket is self-contained, so the last one's context is disposable./implement-spec for the whole spec in one run. It reads the tickets as a task graph, runs implementer subagents across the ready frontier in parallel, and lands everything on one integration branch. Reach for it when you'd rather orchestrate the build than drive each ticket yourself./orchestrate (installed separately) for a parent issue whose sub-issues are genuinely independent. It spawns one /implement agent per sub-issue on its own worktree and owns the mechanical tail (sequencing, relay, merge order, cleanup), but it never re-slices the work; the sub-issues /to-tickets published are the packages. Needs native sub-issues, so GitHub, not local files./implement right here, in the same context window.Either way, the code gets built by driving /tdd (one red-green slice at a time) and closes out with /code-review, a two-axis review (Standards + Spec) of the diff. /implement runs both per ticket; /implement-spec's implementers each drive /tdd, and it runs one /code-review over the integration branch. Reach for /tdd on its own when you just want to build a concrete behaviour test-first without a full spec, and /code-review on its own whenever you want to review a branch or PR against a fixed point.
When the work goes up as a pull request, /pr shapes the body: the smallest visual that shows the change, before/after evidence that it works, and a one-way or two-way door call. It's model-invoked, so the agent reaches for it whenever it writes a PR.
/retro closes the loop. After a build, and especially one that went sideways, it looks back over the session and suggests changes to the agent's environment, not the code: navigation pointers, automated checks, the coding standards /code-review enforces, steering files, tooling. Mechanical mistakes become deterministic checks; judgement calls become coding standards. The next build then starts from a better environment.
Keep steps 1–3 in one unbroken context window (don't compact or clear until after /to-tickets) so the grilling, spec, and tickets all build on the same thinking. Each /implement then starts fresh, working from the ticket. Run /retro in the session it's looking back on, before you clear; after clearing, point it at that session's log instead.
The limit on this is the smart zone: the window (~150k 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; /compact at the nearest phase boundary and carry on (see Phase boundaries).
A starting situation that generates work, then merges onto the main flow.
Bugs and requests piling up → /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: 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 → /diagnosing-bugs. 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 (one command that already goes red on this bug), then fixes with a regression test. Its post-mortem hands off to /improve-codebase-architecture when the real finding is that there's no good seam to lock the bug down.
A huge, foggy effort: a greenfield project or a huge feature build, too big for one session → /wayfinder, the most cognitively demanding flow here. When the way from here to the destination isn't visible yet, it charts a shared map of decision tickets on the issue tracker and resolves them one at a time, producing decisions, not deliverables, until the fog is pushed back and the way is clear. Where /grill-with-docs sharpens an idea you can hold in one session, wayfinder is for the idea you can't, and it's slower and denser, so save it for exactly that, never a well-scoped feature.
When the map clears, it hands off, it doesn't build: merge onto the main flow at /to-spec, which collapses the map's linked decisions into a buildable plan, then /to-tickets and /implement as usual. Looping the map straight into /implement skips that collapse and throws the linked detail away, so go straight to /implement only when the effort turned out genuinely small.
Not feature work, just upkeep.
/improve-codebase-architecture runs 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-with-docs. 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, 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: 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-with-docs drives to keep GLOSSARY.md a clean glossary./codebase-design is 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-codebase-architecture both speak it.A phase is a chunk of work inside a session: the grilling, the implementation, the QA. At the boundary between two of them you have five options, and picking between them is the fuzziest decision in this whole map:
/clear: empty the window, when nothing here matters to what's next./handoff writes a portable markdown file. Narrow: only for a new harness, a new directory, a colleague, or forking a side task mid-phase. What it buys is portability./compact compresses this context and seeds a fresh session with it. The default, at the bottom of the tree rather than the first reach.Read PHASE-BOUNDARIES.md for the ordered tree: the five questions, the reasoning behind each branch, and why the primary-source cost makes Continue the one to rule out first. Make the decision at a boundary; mid-phase, continue or split the rest into subagents.
Off the main flow entirely.
/grill-me: the same relentless interview as /grill-with-docs, but stateless: it saves nothing locally and builds no GLOSSARY.md. Reach for it when you are not working in a working directory (sharpening a plan, a design, a piece of writing, anything with no repo under it). If you are in a working directory, use /grill-with-docs instead: it runs the same interview and leaves a paper trail, so it is strictly the better one./grilling is the interview primitive itself: rounds, the frontier, facts are the agent's job and decisions are yours. /grill-me and /grill-with-docs are the two named ways in, and /triage, /wayfinder and /improve-codebase-architecture all run it internally. Reach for it directly only when you want the interview with no wrapper around it./prototype is a small, throwaway program that answers one design question: does this state model feel right, or what should this UI look like. Throwaway is a constraint on how the code is written, not a promise to destroy it: the answer folds into the real code, and the prototype itself is kept as a primary source on a prototype/<name> branch out of main, pointed at from the implementation issue. 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: 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-with-docs, since research feeds the thinking rather than replacing it./to-questionnaire comes in when the thing blocking you isn't in your head or the codebase but in someone else's, and it writes them a questionnaire to fill in. It's the inverse of /grill-me: instead of interviewing you about the subject, it interviews you about the send (who it's going to, what you need back) and aims the questions at the gap. What comes back is material for /grill-with-docs or /to-spec./wizard is for the steps only a human can take: provisioning infrastructure, setting up credentials or CI secrets, clicking through an unfamiliar third-party dashboard, running a one-off migration or cutover. It generates an interactive bash script that opens each URL, captures each value, and writes it into .env and GitHub secrets, so the procedure stops being something you re-explain to an agent every time. Model-invoked, so the agent reaches for it the moment it hits a wall only you can pass. If the agent could just do it itself, it should; this is for where a human is genuinely in the loop./wait-what is the corrective for a message that didn't land. Use it mid-conversation, inside any other skill, and the agent re-pitches what it just said with the context you were missing, in plain English, using the GLOSSARY.md vocabulary. It works after the fact; /grill-with-docs is the upfront cure, because a shared language agreed early is what stops the jargon arriving at all./step-by-step (installed separately) is for the procedure you have to click through and have never clicked through before: creating a PAT, pointing a domain, wiring a CI secret. It does the terminal half itself, then hands you one numbered block (every field filled with the literal value, every link a deep URL, the trap named in the step it bites) and waits. Where /wizard bottles a procedure into a bash script worth re-running, this one just walks you through it once. Reach for it when the steps are obvious to someone who does this weekly and opaque to you./teach: learn a concept over multiple sessions, using the current directory as a stateful workspace./writing-for-agents is the reference for writing documents agents consume: skills, AGENTS.md, pointed-at docs./setup-matt-pocock-skills: 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.
