Two related fixes to the Connect-External-Agent flow that the user
flagged: the "Need help?" disclosure block in the modal is for the
operator's eyes only — but the agent reading the pasted snippet has
no access to that context. And the docs URL was pointing at a
hostname that doesn't resolve.
User-visible problems:
1. The agent doesn't see the install link, docs link, or the common-
error/check pairs that the human pasted. When the agent fails to
register or hits ConnectionRefused, it can't self-diagnose because
the troubleshooting context lives in a separate UI block.
2. https://docs.molecule.ai → DNS NXDOMAIN. Every "Documentation"
link in the modal was a dead link.
## Fixes
### Move help INTO the snippet (not a separate human-only UI block)
Each of the 7 server-rendered templates in
`workspace-server/internal/handlers/external_connection.go` now
appends a `# Need help?` section with: install link, correct docs
link, and the top common errors as `# • symptom — check` pairs.
Templates updated: curl / channel (Claude Code) / mcp (Universal MCP) /
python / hermes / codex / openclaw. Agents reading the paste now have
the same diagnostic context the human did.
### Drop the duplicated UI block in the canvas modal
`canvas/src/components/ExternalConnectModal.tsx`:
- Removed the `TAB_HELP` per-tab metadata constant (152 lines).
- Removed the `HelpBlock` component (62 lines).
- Removed the `<HelpBlock help={TAB_HELP[tab]} />` render call.
The snippet is now the single source of truth for tab-level help.
### Fix the wrong docs hostname
The actual docs site is `doc.moleculesai.app` (singular `doc`,
`.app` not `.ai`), confirmed by:
- `package.json` description in `Molecule-AI/docs` repo →
"Molecule AI documentation site — doc.moleculesai.app"
- HTTP HEAD on the new URL → 200 for both
`/docs/guides/mcp-server-setup` and
`/docs/guides/external-agent-registration`
- HTTP HEAD on old `docs.molecule.ai` → 000 (NXDOMAIN)
All template docs URLs now point at `doc.moleculesai.app`.
## Verification
- `go build ./...` clean
- `go test ./internal/handlers/... -count=1` green
- `pnpm test` → 1291/1291 pass (unchanged)
- `tsc --noEmit` clean
- 219 LOC removed (canvas duplicate UI), 69 LOC added (snippet help)
- Net `-150 LOC` while gaining the agent-readable help
## Out of scope (deferred, captured in followups)
- One blog post still has `canonical: "https://docs.molecule.ai/blog/..."`
in `src/app/blog/2026-04-20-chrome-devtools-mcp/page.mdx` — separate
blog-content fix.
- Comment in `theme-provider.tsx` references `docs.moleculesai.app`
(with `s`) — comment-only, not a runtime URL.
