# setup-pstack

Sets which model pstack runs for each role and how much reasoning budget it gets, then writes that into a rule file that overrides the skill defaults.

## What it does

The skill builds a role-to-model table for pstack. It starts by listing the model slugs you can actually reach in this session: `Task` in Cursor, `Agent` in Claude Code, `task` in OpenCode, `spawn_agent` in Codex. If your harness has a command that prints your models, the skill uses that instead. A slug it has not confirmed never lands in the file, and `inherit-parent` and `auto` pass either way.

Then comes the budget, one of four: `unlimited` maps to `max`, `large` to `xhigh`, `medium` to `high`, `small` to `medium`. The skill moves the effort token at the end of each slug along `max` > `xhigh` > `high` > `medium` > `low`. Aliases stay untouched, because both mean the role runs on the parent chat model.

Where the file goes: `~/.claude/rules/pstack-models.md` for Claude Code, `~/.cursor/rules/pstack-models.mdc` for Cursor with `alwaysApply: true`, and `~/.agents/pstack-models.md` for everything else. That last one matters. Codex, OpenCode and similar harnesses do not load it by themselves, so pstack skills read it when they pick a model. Grok slugs stop at `xhigh`, so under `unlimited` a Grok role falls back to `xhigh` or gets flagged as needing a choice — check the role list before you confirm.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill setup-pstack -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/setup-pstack/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/setup-pstack/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill setup-pstack -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/setup-pstack/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill setup-pstack -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/setup-pstack/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install backnotprop/pstack setup-pstack
```

2. **Manually: put the files in place**
- File: `.github/skills/setup-pstack/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill setup-pstack -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/backnotprop/pstack --path skills/setup-pstack
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/setup-pstack/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill setup-pstack -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/backnotprop/pstack/tree/HEAD/skills/setup-pstack/SKILL.md

## When to use it
- pin a model to every pstack role without editing the skills
- switch reasoning budget by changing one `# budget` line
- drop all real slugs to `medium` with a single pick
- catch slugs missing from the session before subagents run
- keep a role on the parent chat model with `auto`

## Example prompts
- \`/setup-pstack` with the `small` budget, leave the roles alone
- configure pstack models: run `hardest tasks` on `claude-opus-5-5-max`
- show the pstack role table, then we will change `swarm workers`

# Setup pstack

Write pstack's model settings, one model per role:

- **Cursor:** `~/.cursor/rules/pstack-models.mdc`, an always-applied rule.
- **Claude Code:** `~/.claude/rules/pstack-models.md`. Claude Code loads every file in `~/.claude/rules/` into each new session.
- **Every other harness** (Codex, Pi, OpenCode, and others): `~/.agents/pstack-models.md`. These harnesses don't load it on their own, so pstack skills read this file when they pick a model.

"The settings file" below means the file for your harness. In Claude Code, if that file is missing, read `~/.agents/pstack-models.md` instead, where older versions of this skill wrote it.

## Steps

### 1. Detect available models

Enumerate the model slugs you can pass to a subagent in this session (Cursor `Task`, Claude Code `Agent`, OpenCode `task`, Codex `spawn_agent`). That is the dependable source. If your harness also has a command that lists the user's models, prefer it for completeness (for example `opencode models` or `pi --list-models`). If you cannot detect any, ask the user to paste the slugs they have access to. Never write a real slug you have not confirmed is available. The aliases `inherit-parent` and `auto` are always valid even though they are not detected slugs.

### 2. Load current state

The default role-to-model mapping is the rule shape shown in step 5 below. If the settings file already exists, read it and treat its `# budget` line and its role values as the current choices. Otherwise start from those defaults. A line whose role is not in step 5, such as `how critics`, is from a retired role. Drop it.

### 3. Budget, map, and confirm

**(a) Ask for a budget.** Prefer your structured-question tool (`AskQuestion` in Cursor, `AskUserQuestion` in Claude Code, `question` in OpenCode) over free text. Offer these four options with these exact labels, and name the current budget when the rule records one. With no rule, say that `large` matches the skill defaults.

- `unlimited — max reasoning`
- `large — xhigh reasoning`
- `medium — high reasoning`
- `small — medium reasoning`
```
