ck

Code Katz personas and workflows for Claude Code. One plugin: the product-definition pipeline from an idea to a designed feature, a three-lens decision panel, and 21 personas as subagents and switch commands on three model tiers.

Every document ck writes goes into the repository you opened Claude Code in, under docs/ (or ROADMAP.md and brand/), and is committed with your product. Every document has a contract, so it has the same shape every time, on every project.

Status

Phase one, first release in progress. What runs today:

Command	What it does	State
/ck:next	Says what to run next, in one sentence	Built
/ck:brief <idea>	Toni runs a short market pass, River writes docs/brief.md, a checker validates it	Built
/ck:panel <question>	River, Toni, and Kai argue one question on three different models; a memo shows where they disagree	Built
/ck:prd	River drafts docs/PRD.md from the brief, a checker validates, the panel challenges, River rewrites; you review on a page you can comment on	Built
/ck:team	Who is on this product, who owns what, which seat is missing: docs/TEAM.md	Built; drilled 2026-10-01
/ck:architecture	Akira recommends an architecture from the PRD and roadmap, challenged by Morgan, Alex, and Jordan; you review on a page you can comment on	Built; drilled 2026-10-01
/ck:opportunity <idea>	River frames the idea, Toni, Akira, and a domain seat write sourced sections, River assembles docs/opportunity.md; you review on a page you can comment on	Built; drilled 2026-10-01
/ck:market-research [focus]	Toni plans the questions, researchers answer them from the web in parallel, a cross-check marks what is unsourced or contradictory, Toni writes docs/market-research.md	Built; drilled 2026-10-01
/ck:roadmap	River prioritizes the PRD's requirements into three tiers, Quinn sequences them and writes ROADMAP.md in the roadmap skill's format, with a dated revision entry	Built; drilled 2026-10-01
/ck:brand-guide	Three rounds: Toni positions, Iris designs four to six brand directions, Kai skins a screen in each, you pick from a gallery; the picks are worked up in full as a second gallery; then the brand direction record, docs/brand-guide.md, and the assets under brand/final/	Built; drilled 2026-10-01
/ck:design <feature>	River pulls the feature from the PRD, Kai draws three labeled variants of its screens with their empty, loading, and error states, you pick one from a gallery, then Kai finishes it at full fidelity with docs/design/<feature>/spec.md and Robin adds the acceptance checks	Built; drilled 2026-10-01
/ck:<persona>	Switch this session to a persona, for example /ck:river	Built, all 21
ck:<persona>	Delegate one task to a persona on its own model tier, for example the ck:river subagent	Built, all 21

The specification is the phase-one PRD in code-katz/.github, plans/2026-09-05-ck-plugin-prd-phase-1.md.

Prerequisites

1. Uninstall the old team tool (claude-team-cli). Its persona commands, subagents, and session hook collide with ck's. Steps are below. ck warns at the start of every session while any of it remains.
2. Claude Code 2.1.221 or later, signed in with /login to a Claude account on a paid plan. Dynamic workflows must be available: on a Pro plan, turn them on in /config; an organization can disable them.
3. For review pages with comments: the same version, and a Claude account that can publish artifacts. A page's owner can comment on it on a Max plan; sharing a page with other people needs a Team or Enterprise plan.
4. For development only: Bash 4 or newer, python3, and Node 20 or newer, for scripts/generate.sh and tests/run.sh. The plugin itself needs none of them at run time.

Uninstalling the old team tool

Remove each of these if present:

rm -f ~/.local/bin/claude-team
rm -rf ~/.claude/team

Then remove the persona files it installed under ~/.claude/commands/ and ~/.claude/agents/ (one <persona>.md per persona: river.md, akira.md, and so on), the block it wrote between its markers in ~/.claude/CLAUDE.md, and its SessionStart entry in ~/.claude/settings.json. Start a new session; the warning line is gone when everything is removed.

Install

From the Code Katz marketplace:

/plugin marketplace add code-katz/claude-plugins
/plugin install ck@code-katz

For development, load the checkout directly:

claude --plugin-dir /path/to/ck

After editing a workflow in a running session, run /reload-skills.

How a run works

1. You type a command. If it needs a document you do not have yet, it says which command writes it, and stops.
2. The work runs in the background as a workflow; /workflows shows every agent, model, and token count if you want them. The command itself never prints them.
3. The document appears in your repository. Commands with a review step publish it as a page you can comment on, with the steps in the page's banner. Comment on the page without sending comments to Claude (a comment sent to Claude wakes a cloud session that cannot see your files), then say "done" in your Claude Code session; Claude proposes a change for each comment, applies the ones you approve, republishes the same page, and tells you what changed.
4. /ck:next tells you what comes next.

Where things go, inside your repository:

Document	Path
Opportunity analysis	docs/opportunity.md
Market research	docs/market-research.md
Brief	docs/brief.md
PRD	docs/PRD.md
Team	docs/TEAM.md
Roadmap	ROADMAP.md
Architecture	docs/ARCHITECTURE.md
Brand guide and assets	docs/brand-guide.md, brand/
Design gallery and spec	docs/design/<feature>/
Decision memos	docs/decisions/

.ck/runs/ is a cache for in-progress runs. Nothing depends on it, and ck excludes it from git locally without touching your .gitignore.

Models

Three tiers, set once in tiers.conf:

Tier	Model	Personas
Judgment	Fable 5.1	River, Akira, Morgan, Sage, Jordan, Reiner
Craft	Opus 5	Toni, Kai, Iris, Quinn, Casey, Cornelius, Ernie, Rez, Tracy, Travolta, Noon
Execution	Sonnet 5	Sasha, Alex, Robin, Piper

Validators run on Haiku 4.5. The panel puts its three lenses on three different models: River on Fable 5.1, Toni on Opus 5, Kai moved down to Sonnet 5. A switch command (/ck:river) runs on your session's model; delegation (ck:river) runs on the tier.

Development

Personas live in profiles/<name>.md and tiers.conf. Everything else about a persona is generated:

bash scripts/generate.sh     # agents/, skills/<persona>/, profiles/ROSTER.md
bash tests/run.sh            # the static checks

Edit the profile, never the generated file; the generator refuses to overwrite uncommitted hand edits to generated files unless you pass --force. Every release bumps version in .claude-plugin/plugin.json, or nobody receives it.

Layout:

.claude-plugin/plugin.json   the manifest; name "ck" sets the /ck: prefix
profiles/                    persona source of truth, plus the generated ROSTER.md
tiers.conf                   persona -> model
agents/                      generated subagents, ck:<name>
skills/<persona>/            generated switch commands, /ck:<name>
skills/opportunity, prd, architecture, brand-guide, design, next, review-page
skills/*-artifact/           the ten document contracts
workflows/                   panel, brief, draft (PRD and architecture), team, opportunity-draft, market-research, roadmap, brand, design-round
hooks/hooks.json             usage log on SubagentStart; old-tool check on SessionStart
scripts/                     generate.sh, render-review.py, render-gallery.py, usage-log.sh, check-prereqs.sh
tests/                       run.sh, two fixture projects, the gallery fixtures, and the drill logs
