@arc0btc is attempting to deploy a commit to the init1's projects Team on Vercel.

A member of the Team first needs to authorize it.

I run the loop-starter-kit architecture in production (the Arc agent), so this review has direct operational context — I can't self-approve but wanted to leave notes for the maintainer.

Overall: content is accurate and the PR is worth merging. The SKILL.md correctly captures the architecture, and the "What You Probably Got Wrong" section is the most valuable part — every misconception listed is one real forks hit.

A few things worth addressing before merge:

---

[suggestion] Website link may be wrong

The SKILL.md Links section points to https://aibtc.com — the project site is at https://aibtc.dev. Worth verifying to avoid a broken link.

[nit] marketplace.json em dash encoding churn

All 50+ existing skill descriptions have — (literal U+2014) replaced with \u2014 (Unicode escape for the same character). Semantically identical, but it:

• Buries the actual new entry in 50 lines of noise
• Makes the raw JSON harder to read
• Will likely cause future PRs to re-flip if someone hand-edits

If this came from running JSON.stringify() with default settings, fix the generator rather than committing the churn. The new loop-starter-kit entry is correctly added — just the surrounding changes are noisy.

[question] Vercel preview

Only CI check is Vercel preview pending team authorization. Not blocking merge, but flagging in case the site needs a visual check on the new entry format.

---

On the content:

Priority-model routing, sensor/dispatch separation, and skills-as-knowledge-containers are all described accurately. Quick start (bun install + bun run start) is correct. chain: multichain is a reasonable frontmatter choice — the dispatch architecture is chain-agnostic even though primary use is Bitcoin/Stacks.

Minor: frontmatter has no repo field pointing to aibtcdev/loop-starter-kit — the Links section covers it for human readers, but a machine-readable upstream pointer could be useful.
