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 | $0.00588 | $0.00588 |
| Opus 5.5 | $0.00235 | $0.00235 |
| Sonnet 5.5 | $0.00118 | $0.00118 |
| Haiku 4.5 | $0.00059 | $0.00059 |
Grade A, and why
storefront-skills AGENTS.md 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Storefront Skills — Agent Guide
AI workflows for building high-converting Shopify storefronts with the Lexsis AI MCP (https://mcp.trylexsis.com/mcp).
Skills
Canonical skills live in skills/<name>/SKILL.md (Agent Skills standard,
https://agentskills.io) and are also exposed at .agents/skills/ for agents
that discover that path natively. Invoke by name, or let your agent select from
each skill's description.
The normal reviewed workflow is Setup → Plan → Design → Publish. Optimize scores and improves an existing page with the same plan blocks. Experiments, carts, and quizzes are independent operations. Audit is a read-only report that Optimize can act on. The twelve public commands remain independently invokable; explicit skips are recorded in the task handoff. Pages are authored directly through MCP. Do not reintroduce local page workspaces, source/CSS artifacts, preview builds or local QA gates.
Rules for agents working IN this repo
skills/is the single source of truth. Never editgpt/*— they are generated byscripts/build-distributions.py. The repository root is the Claude plugin package and uses this same physicalskills/tree; do not recreate a second plugin copy underplugins/.- After editing any skill or reference, run
python3 scripts/build-distributions.pyand commit the regenerated output. - Skill frontmatter must satisfy the Agent Skills spec:
nameequals the directory name (≤64 chars, kebab-case);description≤500 chars. - Shared reference docs live in
skills/storefront-engine/references/; thestorefront-enginedirectory is not a public skill. The rule corpora underreferences/page-types/(one contract per page type with a JSON checklist),proof/,offers/,assets/,anti-patterns/,copy/andmcp-playbooks/are loaded byplan-page,design-pageandoptimizeas workflows (each type file's## Workflowplus the universalworkflows/sub-procedures). Validation uses MCP compiler output and hosted review. Repository-only fixture checks live undertests/support/and are not shipped page-authoring steps. Island schemas live inreferences/islands/<name>/schema.json. Do not invent island names or props. - Public skills installed individually must remain self-contained.
scripts/build-distributions.pymaterializes the shared references declared inSKILL_SHARED_REFERENCESinto each consuming skill'sreferences/directory. Edit the shared source, never the generated local copy.
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.
