docs: agents.instacloud.com — canonical onboarding one-liner

[tonychang04]

The short domain is live (ACM + CloudFront edge-caching agents.sh + Route53 alias, verified: full install in 5.3s — parity with agents.railway.com's 5.5s). README leads with curl -fsSL agents.instacloud.com | sh; agents.sh documents both forms; repo skill gains the CloudFront invalidation note (same-PR per its keep-true rule).

Summary by cubic

Make agents.instacloud.com the canonical install one-liner, served via CloudFront as an edge-cached mirror of agents.sh. The raw GitHub URL remains as a fallback, and the docs now include the CloudFront invalidation step.

Summary

Docs-only change that promotes agents.instacloud.com (a CloudFront edge-cache of agents.sh) as the canonical agent-onboarding one-liner and documents the required CloudFront invalidation step in the repo skill — no executable code paths change.

Requirements context

No docs/superpowers/ (nor docs/specs/) directory exists in the repo at head a044dbc — no matching spec/plan found; assessing against the PR title/body alone. The stated intent: make agents.instacloud.com the canonical install one-liner served via CloudFront, keep the raw GitHub URL as a fallback, and document the invalidation step. The skill update correctly honors this repo's own "Keep this skill true — update in the same PR" rule (SKILL.md:62-67).

Findings

Critical

(none)

Suggestion

Security — agents.sh:5 documents a schemeless URL for a curl | sh bootstrap.
The canonical, most-copied command is written as curl -fsSL agents.instacloud.com | sh. curl treats a schemeless host as http://, so the highest-trust moment — fetching a script that is piped straight into sh — begins over plaintext HTTP. If the CloudFront distribution redirects http→https (viewer-protocol-policy redirect-to-https), -L follows it and the body is only ever transferred over TLS, which is safe; but that guarantee lives in infra config not visible in this diff. Note the raw fallback on the very next line (agents.sh:8) already uses an explicit https://. Recommend documenting the canonical form as curl -fsSL https://agents.instacloud.com | sh to remove all ambiguity and not depend on the redirect being present. Same applies to the skill/README wording.

Functionality — PR description claims a README change that isn't in the diff.
The body states "README leads with curl -fsSL agents.instacloud.com | sh", but README.md is not among the changed files and still shows only the native-binary installer line (README.md:13, using install.sh over https://raw.githubusercontent.com/...). Note README's one-liner is the CLI installer (install.sh), which is a distinct artifact from the agent bootstrap (agents.sh), so leading the README with the agents domain may not even be intended. Please reconcile: either include the README edit or correct the description so the PR's stated deliverable matches what shipped.

Information

Consistency — install.sh:8 still points the agents one-liner at the raw URL.
install.sh:8 documents curl -fsSL https://raw.githubusercontent.com/InsForge/insta-cli/main/agents.sh | sh. For a PR whose goal is a canonical short domain, this in-repo reference could also lead with https://agents.instacloud.com (raw as fallback), mirroring agents.sh:5-8. Minor; author's call.

SKILL.md placeholder. SKILL.md:60 uses <the agents distro> for the distribution id — fine as a skill note, but recording the actual distribution id (or where to find it) would make the invalidation step copy-pasteable for the next agent.

Software engineering — no tests warranted. The only executable line (agents.sh:18) is unchanged; the diff is comment text + markdown, so no unit/regression tests are needed and the repo gates (lint + vitest) are unaffected. Good scope discipline — the change is limited to exactly the two files the goal requires, and the skill was updated in the same PR.

Performance — no performance-relevant changes in this PR (documentation only).

Note: the "5.3s full install / parity with Railway" and live CloudFront (ACM + Route53 alias + edge caching) claims in the body are infrastructure assertions that can't be verified from the repo contents; flagging only that they're out of scope for a code-level review, not disputing them.

Verdict

approved (informational — no Critical findings; two Suggestions and a few Information notes above). Posted as a comment; explicit GitHub approval remains a separate human action.
