Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00024 | $0.00505 |
| Opus 5 | $0.00012 | $0.00253 |
| Sonnet 5 | $0.00005 | $0.00101 |
| Haiku 4.5 | $0.00002 | $0.00051 |
Grade A, and why
mockup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Mockup
A persistent alchemist builds 3 genuinely different live HTML options of a visual/interaction idea. You converge by reacting - diverge, refine, polish - new design values solidify to tokens.yaml at acceptance, and the converged mockup graduates on your choice: an immediate tweak, a story, or a parked notebook todo.
This shell owns only routing. The funnel lives in one reference file.
Flow
Step 1: Parse the subject
If args provided: the args are the subject - what to mock up.
If no args: take the subject from the session context (the conversation that led here names it). If nothing in context names a visual subject, ask conversationally - "What are we mocking up?" - no AskUserQuestion; the flow's question budget belongs to the funnel.
Step 2: Single-session guard
One mockup session at a time. Check for an open one:
grep -l "^status: converging" "${CRAFT_PROJECT_ROOT:-.}"/.craft/mockups/*/record.md 2>/dev/null
If a record with status: converging exists, DECLINE the new invocation and point at the open record: name its path and offer to resume it instead. Converged/parked records don't block - only an actively converging one.
Step 3: Run the funnel
Read ${CLAUDE_PLUGIN_ROOT}/commands/references/mockup-inline.md and execute it inline, from Step 1 (Brief), with the subject and session context in hand.
Never invoke the funnel via the Skill tool - a Skill-tool call ends the turn and control never comes back for the next round; inline execution is the contract (see .claude/rules/skill-invocation-chain-breaks.md).
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mockup is a command published in the GitHub repository drobins25/craft (53 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 505 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
