poteto-help

Poteto help

Answer the user's question about pstack, hand them a prompt they can send, and link the file the answer came from. For a help question, don't start the work. The user asked how, and a pstack run spends real tokens, so let them send the prompt.

A message that asks for work, such as "use pstack to fix this bug", is not a help question. Use the poteto-mode skill and do the work under it.

This file maps questions to the skills and guide pages that hold the answers. Those files own the details. Read the file you route to before you quote it, and trust it when it disagrees with this map. Read a sibling skill from the installed skills root. The README and guide pages don't ship with an installed skill, so read them from a pstack checkout when the session runs in one, and otherwise from their public copy. Give the user the file's public copy: https://github.com/mdsmithaustin/pstack/blob/main/ followed by its repository path, such as skills/how/SKILL.md or docs/guide/01-setup.md. A skill's file sits under skills/, so a path relative to the skills root, such as how/SKILL.md, 404s.

Find out what they need

Infer the need from the message and the conversation. A named situation, such as "which skill reviews a PR?", goes straight to its section. If the need is still unclear, ask one multiple-choice question with these options, then answer only the section they pick:

• Get set up
• Start a task with /poteto-mode
• Pick a skill for a situation
• Fix a run that went wrong
• Make pstack my own

Check the state that changes the answer, and mention it only when it does:

• No ~/.agents/pstack-models.md and no workspace .agents/pstack-models.md means /setup-pstack hasn't run for this user, so every role uses its default model.
• No verify-* skill or other app harness in the project means agents have no scripted way to drive the app. Mention /create-verification-skill when the question is about proving a change works.
• No formal verification skill in the project means no property is checked past what tests reach. Mention /create-formal-verification-skill when the question is about a race, an invariant, or another case tests rarely hit. When one exists and the code it covers changed after the commit it records as last in sync, mention /maintain-formal-verification-skill if the question touches that code.

When the models config is missing and it matters, ask whether the user wants to pick a model for each role and a reasoning budget now. It matters when the user is new, the question is about setup or cost, or the answer depends on which models run. Ask at most once per chat. If the need is also unclear, ask both questions together. Offer two choices:

• Now: give them /setup-pstack to type, and answer their question too.
• Later: answer their question, and add one line saying every role keeps its default model until they run /setup-pstack.

Get set up

1. Install from the project root with npx skills add mdsmithaustin/pstack, and pick the targets the user runs. -g installs user-level instead of per-project.
2. Run /setup-pstack. It checks the bundled personas, asks for a reasoning budget, maps a model to each role, and writes ~/.agents/pstack-models.md. Skills read that file the next time they run. On Claude Code it also sets the skill listing, so the skills that load only by name stop showing their descriptions. Then it offers once each to generate a verification skill and a formal verification skill for the project, unless the project already has one.
3. Start a real task with /poteto-mode, a goal, and a check that can pass or fail.

The skills that load from the user's words are listed under Fix a run that went wrong. For invocation behavior and the Claude Code setup requirement, see the README. Guide page 1 covers setup in detail. Offer to word their first prompt with them, per references/prompting.md.

If cost is the worry, say where the tokens go and how to spend fewer. pstack spends extra tokens on subagents and review panels. Rerun /setup-pstack and pick a smaller budget or cheaper models. A role set to auto or inherit-parent runs on the session's model, which saves tokens when the session runs on a cheaper model. A shorter panel list runs fewer subagents, one for each entry. Save /poteto-mode for work that needs rigor.

pstack runs in Claude Code, Codex, Hermes, and Grok Build. Most workflow skills, including /poteto-mode, /how, /why, and /poteto-teach, spawn subagents with per-role models. The pstack-harness skill maps spawning, models, worklists, and loops to each CLI. Hermes has no translation for the shipped Claude aliases, so on Hermes a default role runs on the session model and a default multi-model panel becomes a same-model panel. A Hermes model name written in the models config runs as written.

Start a task with /poteto-mode

/poteto-mode matches the task to a playbook, copies the playbook's opening prose and steps into the worklist, and runs the other skills as the steps need them. A step it skips stays in the list as skipped: <reason>. With the task tools off, the worklist is a numbered list in chat. A good prompt states the goal and how to tell it's done. It doesn't list skills, because a hand-written sequence tends to drop or reorder steps the playbook would keep. Read references/prompting.md before you help word one. Guide page 2 has examples.

/poteto-mode is sticky. Once invoked, it stays on for the conversation, applies itself when a playbook matches or the task needs rigor, and stays out of the way otherwise. The user opts out by saying so. For compaction or truncation, read the mode's recovery rule. Mid-chat, "new task" makes the mode match a fresh playbook. /poteto-mode already uses poteto-agent for the subagents its playbook steps spawn. To get the same style from a subagent of your own, spawn the poteto-agent persona as the pstack-harness skill's Spawn a role section describes. /setup-pstack can register it as a native agent.

Pick a skill

The default answer is /poteto-mode, which runs most of the others when its steps need them. Name a skill directly when the user wants more or less of something than the playbook gives. Read the skill before you recommend it, and give one example prompt.

The user wants to	Skill
Do any non-trivial task with rigor	/poteto-mode
Check that the agent understood their goal and the problem before it starts	/in-your-own-words
Get a prompt rewritten deeper, not bigger, before sending it: what a top professional would add, their raw material and methods, and an outside check. It returns the prompt and doesn't do the task	/sharpen
Know how code works now, or where new code should live	/how
Know why code is shaped this way, or where a number came from	/why
Understand a change or subsystem, explained plainly	/poteto-teach
Catch up on their own recent work on a topic	/recall
Catch up on what changed in this chat since their last message, in plain words and small visuals, with every item waiting on them listed and decidable from the reply alone	/ketchup
Catch up like /ketchup, in a short silent video of slides, with the waiting calls as text under it	/ketchup-video
Know what a small diff could break outside itself	/blast-radius
Settle types and module shape before code that crosses a function boundary	/architect
Get several attempts at one brief, merged into the best one	/arena
Run parallel checks over slices, or race workers, as parallel subagents	/swarm
Have different models review a diff and try to break it	/interrogate
Fix a bug test-first when a cheap local test exists	/poteto-tdd

Clean slop out of the code a branch changed before a commit	/deslop
Clean AI tells out of prose	/unslop
Write docs, an RFC, a README, a PR description, or a commit message to a standard	/technical-writing
Update or review the docs a change affects	/documentation-impact
Hear the last reply again in plain words	/bro

Bring a formal verification back in line after the code it covers changed, and learn whether a failure is drift or a bug	/maintain-formal-verification-skill
Show a PM or designer what the user sees as a chart checked by a model, with each bug drawn as a numbered path, turn an agreed chart into a TLA+ skeleton, or audit the code against its TLA+ spec	/statechart
Write a test invocation, CI gate, or shell assertion that can't pass while measuring nothing	/verify-commands
Find the edge cases and must-nevers in a spec before any code exists	/spec-probes
Probe a running product, feature, or PR for unreported bugs	/runtime-probes

Turn their own working habits into a personal mode skill	/automate-me
Turn what a finished task taught into skill edits	/reflect
Stop agents from repeating the same mistakes in this repo	/correct
Build a page whose buttons wake a Grok Bot over a webhook	/make-bot-ui
Find their way around pstack	/poteto-help

If a skill directory next to this one is missing from the table, read its frontmatter and route by its description. The principle-* directories are covered under principles below.

Close calls:

• /how explains what the code does. /why explains the reasons. /poteto-teach runs one or both and explains the result plainly.
• /arena gives every worker the same brief and merges the best parts. /swarm splits work into slices or a race and returns one report.
• /architect implements right after it settles the design. Add "with checkpoint" to review the design before it writes code.
• /interrogate reviews the diff. /blast-radius looks for breakage outside the diff and proves the one fact that makes the change safe.
• /deslop cleans code. /unslop cleans prose.
• /recall rebuilds context across recent chats. /ketchup covers only this chat since the user's last message. Resuming one specific chat or branch is the Session pickup playbook.
• /figure-it-out designs one rigorous run. The Orchestrate playbook runs a program that spans days and many PRs. The Autonomous run playbook drives one task to a finish condition.

Not in pstack:

• control-cli and control-ui belong to a Cursor plugin. pstack drives the app through the project's own verify-<app> skill, which /create-verification-skill writes.
• /loop is the CLI's wake mechanism, not a pstack skill. Claude Code has one built in. In a CLI without one, re-prompt on an interval or run a watcher subagent.
• pstack has no /orchestrate skill. Orchestrate is a /poteto-mode playbook. If the slash menu shows /orchestrate, another skill set provides it.

Playbooks and principles

Playbooks are step lists inside /poteto-mode, not skills, so they have no slash command. Inside /poteto-mode, describing the task picks one, and these phrases name one directly:

• "babysit this pr" or "check on pr 123" runs Babysit. It drives the PR to merge-ready and stops there. It doesn't merge unless the user asks to merge, land, or ship.
• "review this pr" runs Code review, for someone else's pull request, branch, or diff.
• "land the stack" runs Shipping.
• "take over this branch" runs Session pickup.
• "pause safely" runs Pause safely.
• "full autopilot on this queue" runs Autopilot-full. "stack them, don't ship" runs Autopilot-stack.
• "run the eval playbook" runs Eval.

Without /poteto-mode, a phrase such as "babysit this pr" can start a similarly named skill from the CLI or another skill set instead. The Playbooks section of poteto-mode lists every playbook and when it applies. Guide page 6 covers opening, babysitting, and landing a PR.

pstack has no planning skill. A CLI's own plan mode works alongside it. For work that spans phases or stacked PRs, asking /poteto-mode for a plan runs the Multi-phase plan playbook, which writes the plan and doesn't implement it. For a design question, the Prototype playbook or /architect settles it in code first.

Principles are one-rule skills that /poteto-mode reads and cites in its replies. The user rarely invokes one. They steer with the names instead, as in "apply prove it works. show me the real output." Typing /principle-<name> still loads one on demand. Guide page 8 lists them.

Fix a run that went wrong

Symptom	Fix
The mode stopped applying	Read the README's continuation guidance.
A question got treated as the next step of the last task	Say "new task", or say the turn doesn't need the mode.
A new model choice had no effect	A workspace .agents/pstack-models.md overrides the home file, and a harness section such as ## codex beats a flat line. On Claude Code, a written effort applies only once /setup-pstack has registered pstack's effort agents.
Runs cost more than expected	See the cost paragraph under Get set up.
A skill didn't load on its own	On Codex, and on Claude Code once /setup-pstack sets the skill listing, only /setup-pstack, /how, /why, /unslop, /deslop, /pr-recap, /documentation-impact, /verify-commands, /spec-probes, and /runtime-probes load from the user's words. The others load when the user types them or when another pstack skill, such as /poteto-mode, tells the agent to use them. /poteto-mode doesn't run every skill.
Parallel agents overwrote each other	Give each agent its own worktree.
An overnight run moved but finished nothing	/loop needs a check that can pass or fail, not a duration. See guide page 7.
The reply claims success from a green build	Ask for the real command, flow, stored value, or profile. That's the prove-it-works principle.

For a run that drifts, references/prompting.md has one-line steers. Guide page 10 has more pitfalls and the recipes worth copying.

Make pstack my own

• /automate-me drafts a personal mode skill from the user's own history, to use alongside /poteto-mode.
• /reflect after a session turns its lessons into skill edits the user approves.
• /poteto-mode write a skill for <workflow> runs the authoring playbook. The eval playbook tests a skill change blind.
• Fix a misbehaving skill in its own PR, not inside the feature work where it went wrong.

Guide page 9 covers each of these.

Reply

Lead with the answer. Give at most one example prompt in a code block, adapted from references/recipes.md when one fits, then the link to that file. Keep it short unless the user asked for the whole map.
