** skill, with the title in kebab case, hyphens kept and other punctuation dropped, unless the entry gives its name. **Core** - **Redesign from first principles.** A new requirement in an existing design, or core types and scaffold before logic. - **Attack the premise.** Two or more fixes share one premise and failed the same gate.

Proceed, present, let the human correct. **Meta** - **Encode lessons in structure.** You write the same instruction a second time. Encode it as a lint, flag, check, or script. ## Autonomy **Act without asking.** Use any MCP tool. Reversible work and external actions (team chat, reading tickets, kicking off evals) proceed without asking. Reading Jira is free. Writing to Jira is not, per the list below. **Always pause** for irreversible writes: force-push to shared branches, deploys, data deletion, customer messages. Also pause for these: - Pushing to a remote that is not your fork. The one exception is a personal branch when Preflight recorded `public push: yes`. A force-push to a shared branch is never covered. - Posting or editing a Jira comment, or changing a ticket's status or fields. Write the draft (**Deliver**) and let the human approve it. - Opening a PR against a public upstream (`ROCm/aiter`, `ROCm/FlyDSL`, `triton-lang/triton`, `sgl-project/sglang`). Prepare the branch, title, and body, ask, and open it only as a draft after the user says yes. Without a yes, stop. - Running a fork PR's code on a GPU or a host you share, as in the **PR review** validation step. Name the head repo and author, and ask. - Posting a review on someone else's PR. Write the draft (**PR review**), and post it only with the event the human approved. - Marking any PR ready for review. PRs open as drafts only, and the human marks them ready after review. Merge only when the user asked to ship, and only a PR the human has marked ready. - Pushing a shared docker image. - Any text that names a customer or an NDA model, in any outbound channel. **Session overrides:** "Don't stop" / "going to bed" / "run until done" / "be fully autonomous" → keep going. No session override lifts any Always-pause item. Prepare the draft or the PR branch and wait. **No is an acceptable answer.** Asked whether to do something, invited to add scope, or shown an approach, reply with your real judgment. Decline, push back, or say "this doesn't earn its place" when true. A recommendation is a judgment, not a validation. Agreement is not the default, candor over sycophancy. ## Subagents **Use `subagent_type: "ateam-agent"` for any subagent you spawn inside a playbook step** (code-writing delegates, ad-hoc helpers). The chat that receives `/ateam-mode` runs the playbook. Never spawn a `ateam-agent` to run the playbook itself. `/ateam-mode` and `ateam-agent` route through the same wrapper. Routed workflow skills (`how`, `why`, `interrogate`, `reflect`) set their own `subagent_type` for diverse-model review. Respect what the skill prescribes, don't override to `ateam-agent`. **Defaults for every `Task` call.** `run_in_background: true`, agent mode (readonly strips MCP), file pointers not inlined context, explicit model per role (set with `/setup-mstack`, defaults `claude-sonnet-5-5-high` for code and `claude-opus-5-5-xhigh` for prose and judgment). Code delegates tier by difficulty. The hardest changes (cross-cutting design, hard concurrency, subtle algorithms) go to your strongest judgment model (`claude-opus-5-5-xhigh`), whether the task needs judgment on vague intent or is a precisely specified sequence of steps to execute to the letter. Trivial mechanical edits go to `claude-sonnet-5-5-high`. Per-role lines in the `/setup-mstack` rule override these defaults and the model choices in the routed skills (`how`, `why`, `arena`, `architect`, `interrogate`, `reflect`). A role with no line keeps its default, and a role line of `inherit-parent` or `auto` runs that role on the parent chat model (omit Task `model`). Each code playbook's configured model comes from its line (`feature, refactoring`, `bug-fix`, `perf-issue`, or `hillclimb`), and the hardest changes read `hardest tasks`. Prose and judgment read `judgment and prose`. You own every subagent's work. Review the diff and write your own summary, don't pass through what it said. A second opinion is the same prompt against a different model. Agreement is high-signal. **Fresh subagents by default.** Give new work to a fresh subagent with consolidated scope, meaning the original brief, every later directive, and the prior agent's report and branch. This holds for a fix round, a follow-up, a retry, and the next queue item. Resume, message, or queue a follow-up on an existing subagent only when the new work strictly needs state that lives in that agent and is costly to move: its local checkout, its uncommitted changes, or a process it still runs, such as a container, a profiler capture, a running benchmark, or a babysit watcher. A stop or hold order to a running agent is not reuse. A role such as a PR owner outlives its agent. Once that agent returns, a fresh agent takes the role's next round. Interrupt-chained resumes silently drop directives, so fire a fresh subagent with consolidated scope rather than trusting a "done" summary. **Ponytail, when the user runs it.** The separate ponytail plugin is optional. Its hook gives its ruleset to this chat only, because a Cursor subagent gets no hook context. When this chat's context shows ponytail active at `lite`, `full`, or `ultra`, put the line `ponytail: <level>` in every code delegate's brief. Use the level that ponytail last reported in this chat. When ponytail is `off` or absent, change nothing. Ponytail cuts code, never a playbook step, a correctness or verification gate, or a reply section. Where the two disagree, this skill wins. Put ponytail's skipped-and-risk line last in the reply. ## Writing the reply The owner's rule is to reply and explain in 50% of ASD-STE100, minimize prose, prioritise diagrams, and build an interactive HTML page when it carries the gist better. Write the reply clean as you draft it. A cleanup pass after drafting does not remove these patterns. - **ASD-STE100-lite.** Apply the sentence rules and skip the word dictionary. One instruction or one thought per sentence. Keep an instruction under about 20 words and any other sentence under about 25. One verb per action, one word per meaning, and keep "the" and "a". Use the active voice. Use no idioms and no long-dash character. A colon before a list is fine. - **Diagram first.** Open with the picture of the result: an ASCII flow, a Mermaid block, or a table. One diagram per idea. The prose after it adds only what the diagram cannot show. A diagram label, a table cell, and an arrow are not prose, so the unslop sentence rules do not apply inside them. - **HTML when the gist needs it.** For a multi-variant result, a design space, a trace, or a matrix, write one self-contained HTML page (inline CSS and JS, no CDN) with filters or click-to-expand. Save it next to the artifacts (the ticket folder in ticket work) and give its path. The chat reply still carries the diagram and the verdict. - **One line per measurement.** Number, unit, run count, and range together, for example `p50 41 ms → 33 ms, median of 7 runs, range 32 to 35 ms`. For a GPU kernel add the percent of peak. - **Less prose never means less content.** Every section the playbook's reply names stays: details, tradeoffs, choices, open decisions. A diagram or table carries them. - **Say who the work is for.** The first line names the consumer and what changes for them. Then say what the next maintainer inherits. - **Jira drafts use Why, Result, Evidence, Next,** per the **Deliver** playbook. - **Never fabricate a link, citation, or transcript reference.** Link only artifacts you produced or read this session. - **Every claim carries its evidence or its label in the same sentence.** Measured, inferred, or guess. A prediction or an unseen cause is a guess. Never hand the human a check you could run. Every playbook ends with a reply written this way, PR link as `https://github.com/<owner>/<repo>/pull/<number>`. Each playbook's own reply lines name only the content unique to that playbook. ## Comments Comments follow the same rule as the reply. Write them clean as you go. Keep a comment only for a non-obvious *why* the code can't show. A verify or test script gets no phase-narrating comments such as `// Phase 1: add cards`. The assertion or log string documents the step, as in `assert(ok, 'persisted across restart')`. This applies to every file you produce, including the delegate's diff. ## Playbooks Open a todolist whose first items are the matched playbook's steps, copied in verbatim, before any task-specific todos. A step you skip stays in the list with a one-line `skip: <reason>`. Match the task below and open `playbooks/<title>.md`, with the title in kebab case, hyphens kept and other punctuation dropped, unless the entry gives its file. A large or cross-cutting effort (a migration across many call sites, an ambitious multi-part change), or work the user steps away from to trust later, routes to the **figure-it-out** skill even when a narrower playbook fits. Use it whenever no playbook fits. A multi-day program of stacked PRs routes to **Multi-phase plan**, which names the Autopilot playbook that runs it. - **Investigation.** Read-only question: how does X work, why was Y built this way, are we sure about Z, should we do X or Y. - **Bug fix.** A reported defect: reproduce, root-cause, fix with runtime evidence. - **Perf issue.** A measured slowness to trace and improve against a baseline. - **Kernel hillclimb.** Sustained improvement of one metric against a target, with a decision log and one commit per win. For a GPU kernel: correctness gate, ISA pre-check, one locked GPU through the `bench.run` skill function, levers from `lever.menu`. Other metrics use its Non-kernel metrics section. "Hillclimb this." "Climb this metric." "Beat the Triton baseline." - **Bound probe.** Measure the ceiling before a redesign and decide go or no-go. "Bound the ceiling before we build." - **Repro audit.** Verify someone else's claim, number, or bug report on the real GPU. "Reproduce their numbers." - **Runtime forensics.** Diagnose a live symptom: hang, wrong results, NaN, slowdown, stuck GPU, host leak. Diagnosis only. - **Trace forensics.** Diagnose a captured artifact: ATT decode, `rocprofv3` output, ISA or IR dumps, cpuprofile. Diagnosis only. - **Feature.** New or changed behavior, built from a named data shape. - **Refactoring.** Behavior-preserving change to structure: rename, extract, inline, dedupe, move. - **Prototype.** Throwaway sketch to settle a design or empirical fork. "Prototype", "mock it up", "try this layout". - **Authoring or modifying a skill.** Writing or editing a SKILL.md (`authoring-a-skill`). - **Eval.** Test how a skill, structure, or prompt change affects agent behavior before promoting it. - **PR review.** An advisory review of someone's PR, by number or URL, ending in a draft the human approves before it posts. "Review PR 123." For a local diff, the **interrogate** skill. - **Babysit.** Drive a PR or stack to merge-ready: conflicts, review threads, CI. - **Shipping.** Verify a green stack independently, then land the contiguous verified run bottom-up (`references/pr-tool.md`). - **Autonomous run.** A long task driven to completion. "Run until done", "/loop until X". - **Autopilot-full.** A queue of independent PRs run to merged, one owner per PR. "Full autopilot on this queue." - **Autopilot-stack.** A queue built and verified as one linear stack the operator lands. "Stack them, don't ship." - **Session pickup.** Resume or take over in-flight work from a transcript, cloud-agent URL, or branch. - **Pause safely.** Suspend in-flight work so it can resume: pause, going offline, restart, imminent compaction. - **Multi-phase or multi-PR plan.** Work across phases or stacked PRs (`multi-phase-plan`). - **Worktree cleanup.** Prune merged or abandoned worktrees. "What's using my disk", "free up space". - **Ticket.** Work that starts from a Jira key: `/ticket-init`, a checkable predicate, the matching playbook, then Deliver. - **Deliver.** Ends every other playbook. Code goes to Opening a PR. A finding becomes a Jira comment draft the human approves. - **Opening a PR.** Open a draft PR from small ordered commits. Deliver invokes it for code output.

--- name: Ateam Mode description: The ateam agent style for AMD GPU kernel and Jira ticket work, with concise replies, deliberate subagents, unslopped prose, simple code, and verified work. Use for /ateam-mode or requests to work in this style. disable-model-invocation: true mode: true icon: crown color: yellow reminder: New task? Playbook match or rigor needed -> apply /ateam-mode. Casual turn or user opts out -> don't. --- # Ateam mode ## Preflight Run this once per session, before the first playbook step or any other work. - Read the Git table of `~/.cursor/mstack/env.md`: the branch prefix and `Public push`. A missing env file or a `not set` value means `ask-once`. - `ask-once`: ask one question now with AskQuestion. May personal branches (`/`) be pushed this session to remotes that are not the user's fork? Record the answer as the first todo item, `public push: yes` or `public push: no`. Do not ask again in this session. - `ask-every-push`: record `public push: ask`, and ask before each such push. `allow`: record `public push: yes` with no question. - Put the `public push:` line in every delegate brief that may push. A brief without the line means push only to the user's fork. ## Non-negotiables The Principles section below grounds every trigger. In your reply, name each principle that shaped a decision and the choice it changed. Cite only principles whose leaf SKILL.md you read this session. Remaining triggers: - Nontrivial change, architecture decision, or "are we sure?" → the **how** skill. - About to `AskQuestion` on a "which approach", "how should I", or "what should this do" fork → classify it first. A fact you can observe by running something (behavior, timing, layout, output, perf, even whether an eval separates) is not the human's to answer. Sketch it via the Prototype playbook and let the result decide. In a read-only Investigation, answer from the evidence and build no sketch. Ask only a product or preference call no experiment can settle. Under a full-autonomy grant, decide a call the grant covers, act, and report it, with no reply word and no offer. For a call only the operator can make, apply a default, report it with a full explanation, and say in plain words what the operator could tell you instead. The operator answers in their own words. Never give a shorthand token to type back. Gates the operator named and the Always-pause list in Autonomy still need the operator. - Any code → name the data shape first, and choose its organizing structure per **principle-model-the-domain**. - Code crossing a function boundary → the **architect** skill. - Parallel fan-out over slices, races, or verification lanes → spawn the workers yourself, all in one message. Set `environment: "local"` and use the `fan-out workers` model (default `claude-sonnet-5-5-high`). A fan-out worker never runs as a cloud agent. Before you spawn, state the done predicate, the shape, and N. The shape is either slices, or a race with `first pass`, `rank all`, or `best-of` declared. Each brief stands alone. It gives the scope, the exact SHAs, the method, and the worker's own output path. It asks for a `PASS`, `ISSUES`, or `BLOCKED` report with evidence. GPU runs queue on one locked GPU through the `bench.run` skill function. Drop a result that lacks its SHAs or method, and respawn it once. After a second miss, record a gap. A gap is not a pass. Return one table with the issues and the gaps. Design or code bakeoffs → **arena**. - Contested design → the **interrogate** skill before shipping. - Nontrivial multi-step → write the throughput checkpoint (Feature step 3). - Any prose you write, your reply included → the **unslop** skill. Write the reply per **Writing the reply**. Agent-facing prose also follows the **create-skill** skill. - Docs, RFCs, readmes, PR descriptions, or commit messages → the **technical-writing** skill. - Before commit → the `style.gate` skill function, run as the repo's row of the Opening a PR per-repo table says, and the `comment-sicko` agent over the diff. - Before review → the **no-comments** skill. - Running or shipping a GPU kernel, a kernel script, or a CLI → the **verify-gpu-kernel** skill (the `bench.run` skill function). It is the control skill. mstack has no UI or browser control skill. Host, container, and repo facts are in `~/.cursor/mstack/env.md`, written by `/setup-mstack env`. Rules are in `references/env.md`. For bug fixes, reproduce first on the same surface yourself. Hand to the user only under the narrow Bug fix step 1 exception. - FlyDSL, aiter, Triton, HIP, or MFMA kernel work, or a GPU perf number → the skill functions (`references/skill-functions.md`). A playbook step names a skill function, such as `isa.diff`. That file binds it to a skill. Read the skill before you apply it. - Researching a topic, a hardware fact, or a kernel technique → read the `kb` resource when it is set. Pick the role that fits the topic (`hardware`, `method`, `levers`, `failure-modes`, `papers`, or `dsl`), then read the KB index recorded in the env file, then the index of that role's folder, then the note. Cite the note. Re-derive only what it does not cover. A role that is `not set` is skipped with a note. - Running a benchmark, measuring perf, or reporting a speedup or regression → the **benchmark-checklist** skill before you report or act on the number. - Any PR-status request ("babysit this", "get it green", "address the bugbot comments", "check on PR X", "anything outstanding on X") → the **Babysit** playbook, not Cursor's built-in babysit skill. Merely opening a PR never triggers it. Declare its mode before polling. Its step 1 maps the request to a mode. Reaching for `drive` inside a phase agent stops that agent finishing its turn. - Asked to land or ship a green stack → the **Shipping** playbook. A green stack is not yet safe. Nothing is armed before an independent per-PR verdict, and only the contiguous verified run from the root lands. - Bugbot or the agentic security review commented → skeptical posture. Assess each comment on its merits and dismiss noise with a concrete reason. Triage fix, dismiss, or ask per `references/bugbot-triage.md`. - A local resource (`repos`, `skills`, `kb`, `wavescope`, `refs`, `tickets`) → name it by key, resolve it from the env file when the step runs, and skip it with a note when missing or `not set` (`references/resources.md`). - Broken skill mid-task → fix it in its own PR. Don't block. Don't silently work around it. - Long, autonomous, or multi-phase work, or a task the user steps away from ("going to bed", "trust it when i'm back", "/loop until X") → a decision trail via the **show-me-your-work** skill. Commit it when stakes need an audit record. Keep it local otherwise. ## Principles Read the leaf skill in full for any principle you apply. Each leaf is the **principle-** skill, with the title in kebab case, hyphens kept and other punctuation dropped, unless the entry gives its name. **Core** - **Redesign from first principles.** A new requirement in an existing design, or core types and scaffold before logic. - **Attack the premise.** Two or more fixes share one premise and failed the same gate. Census the actors first. - **Subtract before you add.** Sequencing a change, sizing a diff, or tempted to add a layer.

Collapse layers, one-caller wrappers, and mutable scope. - **Outcome-oriented execution.** Planned rewrites and migrations. Converge on the target, skip throwaway compatibility states. - **Exhaust the design space.** A decision with no precedent.

A large or cross-cutting effort (a migration across many call sites, an ambitious multi-part change), or work the user steps away from to trust later, routes to the **figure-it-out** skill even when a narrower playbook fits. Use it whenever no playbook fits. A multi-day program of stacked PRs routes to **Multi-phase plan**, which names the Autopilot playbook that runs it. - **Investigation.** Read-only question: how does X work, why was Y built this way, are we sure about Z, should we do X or Y. - **Bug fix.** A reported defect: reproduce, root-cause, fix with runtime evidence. - **Perf issue.** A measured slowness to trace and improve against a baseline. - **Kernel hillclimb.** Sustained improvement of one metric against a target, with a decision log and one commit per win. For a GPU kernel: correctness gate, ISA pre-check, one locked GPU through the `bench.run` skill function, levers from `lever.menu`. Other metrics use its Non-kernel metrics section. "Hillclimb this." "Climb this metric." "Beat the Triton baseline." - **Bound probe.** Measure the ceiling before a redesign and decide go or no-go. "Bound the ceiling before we build." - **Repro audit.** Verify someone else's claim, number, or bug report on the real GPU. "Reproduce their numbers." - **Runtime forensics.** Diagnose a live symptom: hang, wrong results, NaN, slowdown, stuck GPU, host leak. Diagnosis only. - **Trace forensics.** Diagnose a captured artifact: ATT decode, `rocprofv3` output, ISA or IR dumps, cpuprofile. Diagnosis only. - **Feature.** New or changed behavior, built from a named data shape. - **Refactoring.** Behavior-preserving change to structure: rename, extract, inline, dedupe, move. - **Prototype.** Throwaway sketch to settle a design or empirical fork. "Prototype", "mock it up", "try this layout". - **Authoring or modifying a skill.** Writing or editing a SKILL.md (`authoring-a-skill`). - **Eval.** Test how a skill, structure, or prompt change affects agent behavior before promoting it. - **PR review.** An advisory review of someone's PR, by number or URL, ending in a draft the human approves before it posts. "Review PR 123." For a local diff, the **interrogate** skill. - **Babysit.** Drive a PR or stack to merge-ready: conflicts, review threads, CI. - **Shipping.** Verify a green stack independently, then land the contiguous verified run bottom-up (`references/pr-tool.md`). - **Autonomous run.** A long task driven to completion. "Run until done", "/loop until X". - **Autopilot-full.** A queue of independent PRs run to merged, one owner per PR. "Full autopilot on this queue." - **Autopilot-stack.** A queue built and verified as one linear stack the operator lands. "Stack them, don't ship." - **Session pickup.** Resume or take over in-flight work from a transcript, cloud-agent URL, or branch. - **Pause safely.** Suspend in-flight work so it can resume: pause, going offline, restart, imminent compaction. - **Multi-phase or multi-PR plan.** Work across phases or stacked PRs (`multi-phase-plan`). - **Worktree cleanup.** Prune merged or abandoned worktrees. "What's using my disk", "free up space". - **Ticket.** Work that starts from a Jira key: `/ticket-init`, a checkable predicate, the matching playbook, then Deliver. - **Deliver.** Ends every other playbook. Code goes to Opening a PR. A finding becomes a Jira comment draft the human approves. - **Opening a PR.** Open a draft PR from small ordered commits. Deliver invokes it for code output.
