Closes #33.

Commands generated from /{account_or_zone}/{account_or_zone_id} paths already
run against the account by default, switch to a zone with --zone, and show
the chosen scope in --dry-run. This PR covers the rest of the issue:

• Help: those 124 commands now say how they pick a scope.
• Missing context: --zone without a value now fails. Before, it switched
  to zone scope with no zone ID.
• Tests: CLOUDFLARE_ZONE_ID on its own keeps the account route. A command
  fails before any request when no account can be picked (a zone name needs
  one too) or the --zone name isn't found.

Before and after

1. Help explains which scope runs

Before, help only repeated the API description:

$ cf load-balancers account list --help
cf load-balancers account list

List configured account or zone-scoped load balancers.

Global flags
  ...

After, two lines say how the scope is picked:

$ cf load-balancers account list --help
cf load-balancers account list

List configured account or zone-scoped load balancers.

Runs against your account. Pass --zone to run against a zone instead.
CLOUDFLARE_ZONE_ID is ignored.

Global flags
  ...

2. --zone without a value fails

Before, the command switched to zone scope with an empty zone ID, so the
preview shows zones//:

$ cf load-balancers account list --zone --dry-run
{
  "command": "cf load-balancers account list",
  "method": "GET",
  "url": "https://api.cloudflare.com/client/v4/zones//load_balancers",
  "pathParams": {
    "account-or-zone": "zones",
    "account-or-zone-id": ""
  },
  "bodyKind": "none"
}

After, it stops with an error:

$ cf load-balancers account list --zone --dry-run

┌ Error
│ --zone requires a non-empty value.
└

Notes

• These commands ignore CLOUDFLARE_ZONE_ID, so a variable set for zone-only
  commands can't quietly redirect them.
• The global --zone is now validated like --mode: an empty value,
  --no-zone, or a repeated --zone fails. An empty value used to fall back
  to CLOUDFLARE_ZONE_ID only because an empty string is falsy, so this ships
  as a patch.
• Pass-through commands still need -- before arguments that clash with cf's
  global flags. cf containers ssh <id> ls -z now fails instead of silently
  dropping the -z.
• --dry-run makes no requests, so it doesn't resolve a zone name:
  --zone example.com --dry-run previews /zones/example.com/…, as zone-only
  commands already do.
• The "no account" error comes from @cloudflare/workers-auth and doesn't
  mention --zone. I've left it as is.

💬 Approved with comments — The generator, runtime validation and regenerated commands look correct and are tested. One suggestion: the changeset should mention the change to how pass-through -z arguments behave.

🔧 Fix with your agent

Paste the following into your coding agent to investigate and fix these issues.

Fix the following code review issues found in pull request #422.

Before making changes, review each issue and present a brief summary table:
- For each finding, state whether you agree, disagree, or need clarification
- If you disagree (e.g., the fix would require disproportionate changes
  for minimal ROI, or the finding is factually incorrect), explain why
- If you need to clarify something before deciding, ask those questions
- Then share your plan for which issues to tackle and in what order

## SUGGESTION (1)

### [Release] `.changeset/empty-zone-flag.md`: say that pass-through arguments containing `-z` (e.g. `cf containers ssh <id> ls -z`) now fail unless they come after `--`.
- **File:** .changeset/empty-zone-flag.md:11

🚀 Release: 💬 1 suggestion

The changeset leaves out a pass-through behaviour change

Recommendation: 💬 Optional Nits

• [SUGGESTION] .changeset/empty-zone-flag.md: say that pass-through arguments containing -z (e.g. cf containers ssh <id> ls -z) now fail unless they come after --. (.changeset/empty-zone-flag.md:11)

View full review

.changeset/empty-zone-flag.md:7-11 describes the rejection of empty and repeated --zone values. It does not say that an unseparated -z in pass-through arguments (for example cf containers ssh <id> ls -z) now fails instead of being silently dropped, or that the fix is to put -- before those arguments. That workaround currently appears only in the pull request description. Adding a sentence to the changeset would put it in the release notes.

✅ All other checks passed

🔒 Security: ✅ LGTM

No security problems found. With the new validation, an empty --zone can no longer send a request to a /zones// path. Because these commands ignore CLOUDFLARE_ZONE_ID, a zone ID set in the environment can no longer redirect them.

---

📖 AGENTS.md: ✅ LGTM

The change follows the repository conventions. The generated output was produced by changing the generator plugin, not by editing _generated/ files by hand, and there is a changeset for each user-facing change.

---

📋 Code Quality: ✅ LGTM

No problems found in the generator changes (emit/handler.ts, files.ts), the --zone validation in src/index.ts, or the regenerated command files. The new tests cover the empty, --no-zone and repeated --zone cases, and they check that CLOUDFLARE_ZONE_ID is ignored by commands that can run against an account or a zone.

---

⚡ Performance: ✅ LGTM

No performance concerns. The changes add help text and a check on the flag value at startup.

---

📝 Documentation: ✅ LGTM

The docs/architecture.md addition and the help text match the behaviour that was implemented.
