Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00138 | $0.02197 |
| Opus 5 | $0.00069 | $0.01099 |
| Sonnet 5 | $0.00028 | $0.00439 |
| Haiku 4.5 | $0.00014 | $0.00220 |
Grade A, and why
shopify-redirect-mapping scanned grade A with 1 finding 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 12d 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.

Shopify Redirect Mapping
Turn a list of 404ing URLs into live 301 redirects on a Shopify store using
type-aware fuzzy matching with a manual review queue for the leftovers. The job
is reclaiming search equity and rescuing lost visitors, not building a perfect
1:1 map. For bulk apply through a spreadsheet instead of the API, hand the final
map to the sibling shopify-matrixify skill's Redirects sheet.
The one rule that matters: recall over precision
A wrong-but-related redirect beats a 404. A visitor who lands on a close product or the right category still converts; a visitor who hits a dead page leaves. Google keeps some of the old page's equity when the 301 points somewhere topical; it keeps none when the URL 404s. So tune for coverage, not for a flawless match, and let a human review pass catch the misfires.
Worked case (an automotive-lifestyle brand, anonymized). A first pass used a single conservative 0.92 similarity threshold across all URL types. Out of 1,010 dead URLs it produced 6 redirects: effectively nothing, and the merchant called it useless. Re-running with per-type thresholds plus cross-type fallbacks yielded 725 live redirects (~72% coverage) from the same export. The lesson is blunt: do not ship a conservative first pass. Precision-first thresholds look safe and deliver nothing.
Per-type thresholds (defaults, not suggestions)
Different URL types tolerate different looseness. Classify each dead path by its prefix, then match it only against live inventory of the same type at these cut-offs:
- Products: 0.85. Accepts some "same suffix, different product" matches (a
discontinued
-jacketlanding on another-jacket). That is the acceptable cost of recall; the review pass pulls the ones that are genuinely wrong. - Collections: 0.70. Most dead collection URLs are restructure churn. Any nearby collection is a better landing than the homepage.
- Blogs / pages: 0.85. Brand pages that resolve to collections: 0.70. The review queue catches the rest.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

shopify-redirect-mapping is a skill published in the GitHub repository kgelster/awesome-ecom-skills (46 stars, last pushed 20d ago), licensed MIT. It adds 138 tokens to every session and 2,197 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
