What is discover-rule-topics?

A research tool for finding recurring patterns in Shopify themes, which are reusable designs and code for online stores.

It helps explore Shopify areas such as CSS patterns, cart APIs, or metafields and turn undiscovered patterns into a rule backlog.

It helps identify useful subjects for future coding rules without duplicating topics already covered in the project.

Token cost

What it costs to keep this loaded

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	$0.00055	$0.01651
Opus 5.5	$0.00022	$0.00660
Sonnet 5.5	$0.00011	$0.00330
Haiku 4.5	$0.00006	$0.00165

Security

Grade A, and why

discover-rule-topics 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 2mo 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.

Discover rule topics from Shopify themes

You are exploring Shopify themes to discover patterns, techniques, and conventions that could become AI-consumable rules. Your goal is to enrich the topic backlog, NOT to write rules.

The search focus is: $ARGUMENTS

If $ARGUMENTS is empty or very broad (e.g., "general", "explore"), perform a wide exploration across multiple categories. If it names a specific area (e.g., "CSS patterns", "cart AJAX API", "metafield traversal"), focus your search on that domain.

Read these files before starting:

references/category-definitions.md -- extended category taxonomy with search hints
references/existing-coverage.md -- what Shopify's Horizon cursor rules already cover (avoid re-discovering these)
rules/BACKLOG.md -- existing topic backlog (don't re-discover these)
rules/INDEX.md -- completed rules (don't suggest already-covered topics)

Phase 1 -- Orient

Parse $ARGUMENTS to determine the search scope:
- Focused: a specific technology area, pattern type, or Shopify feature
- Broad: no arguments, or a high-level term like "explore" or "general"
Read rules/BACKLOG.md to load existing topics.
Read rules/INDEX.md to load completed rules.
Check for Horizon cursor rule coverage using the three-level approach:
- If shopify-themes/horizon/ is present, list files in shopify-themes/horizon/.cursor/rules/ for the latest coverage.
- If Horizon is not present, consult references/existing-coverage.md for a summary of what Shopify's cursor rules cover.
- Either way, also check references/existing-coverage.md for the "What is NOT covered" section -- these are prime opportunities for new rules.
Build an exclusion set from all sources -- these are topics you must NOT re-discover.

Phase 2 -- Search

Search across all themes in shopify-themes/. Use Explore agents to parallelize searches.

If shopify-themes/ is empty or contains no themes, lean on web research instead. Suggest the user adds themes to shopify-themes/ for richer discovery -- see the project README for recommended themes (Dawn and Horizon as starting points).

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.
