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 | $0.00008 | $0.00128 |
| Opus 5 | $0.00004 | $0.00064 |
| Sonnet 5 | $0.00002 | $0.00026 |
| Haiku 4.5 | $0.00001 | $0.00013 |
Grade A, and why
frontend-performance-engineer 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 6d 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
Spawn an agent team named "frontend-performance-engineer" using the stored team definition.
- Read the team configuration from
${CLAUDE_PLUGIN_ROOT}/teams/frontend-performance-engineer.md. Frontmatter may includemodelandsizehints; body holds the team's instructions. - Create an agent team that follows those instructions. Honor
modelandsizehints if present. - Incorporate this additional user context into the spawn prompt (may be empty): $ARGUMENTS
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.

theme-swap
Recolour an extracted site's design around a new brand primary. OKLCH hue rotation preserves perceptual lightness — neutrals, type, spacing, and motion stay untouched. Side-by-side HTML preview + recoloured tokens (DTCG, Tailwind, shadcn, Figma).
gallery
Build a static, shareable gallery from your fidelity reports — an index of score cards plus a permalink page (with an OG card) per clone.
remix
Restyle a site in another design vocabulary — brutalist, swiss, art-deco, cyberpunk, soft-ui, or editorial. Preserves page shape, swaps the visual vocabulary.
studio
Launch the local design Studio — a live token editor over the latest extraction. Edit, preview a wall of real components, toggle dark mode, inspect motion, and export.
