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.

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 | $0.00017 | $0.00394 |
| Opus 5 | $0.00009 | $0.00197 |
| Sonnet 5 | $0.00003 | $0.00079 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
backend-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 today.
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.

A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

backend-engineer is an agent published in the GitHub repository gracefullight/krds (46 stars, last pushed today), with no licence file. It adds 17 tokens to every session and 394 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 2026-09-01.
Other agents, from other repositories
preview-html-author
Use ONLY as part of the /design-md skill pipeline. Builds one self-contained preview HTML file (preview.html) carrying both themes, which visually demonstrates a design.md's tokens and components. Hero on top + component showcase grid below. Writes to staging only — never to public/preview/ directly.
design-md-author
Use ONLY as part of the /design-md skill pipeline. Translates a research.md into a Stitch v0.1-formatted draft.md with ko-design-md project frontmatter. On revision passes, incorporates feedback from the prior review-{N}.json. Writes draft to staging only — never to services/.
preview-html-reviewer
Use ONLY as part of the /design-md skill pipeline. Scores preview.html against the approved design.md and references/rubric-preview.md, producing a preview-review-{N}.json. Read-only on inputs; writes only the review JSON.
design-md-reviewer
Use ONLY as part of the /design-md skill pipeline. Scores a draft.md against research.md and references/rubric-design.md, producing a review-{N}.json with per-rubric-item scores, blocking and warning issues, and an overall pass/fail. Reads only — never edits the draft.
research-collector
Use ONLY as part of the /design-md skill pipeline. Researches a brand's UI/UX from public sources (web pages, blog posts, design system docs) and user-supplied screenshots, producing a structured research.md with citation-numbered claims. Do not invent facts — every concrete claim must trace to a fetched source or a…
