arcq 1.0.0

Initial public release.

Commands

• arcq query <layer> "<where>" - query a layer and print feature attributes as a JSON array, with automatic pagination; arcq <layer> "<where>" shorthand. Shaping flags: --out-fields, --limit, --count, --order-by, -q/--quiet.
• arcq services add <name> <url> - register a named FeatureServer/MapServer service.
• arcq refresh / arcq sync - index every configured service's catalog and generate servicename-layername shortcuts.
• arcq use [name] - select the active layer, interactively (fzf) or by name; arcq active prints the selection.
• arcq fields [layer] - field metadata as JSON; arcq layers and arcq list <service> for discovery.
• arcq token set / arcq token show - manage the auth token, stored at ~/.arcq-token with mode 600.
• arcq version / --version / -V.

Design contract

• Exit codes: 0 success (an empty [] result is success), 1 error, 2 token invalid or expired. ArcGIS hides failures inside HTTP-200 bodies; arcq surfaces every one of them and exits non-zero.
• stdout carries only JSON results; summaries, warnings, and errors go to stderr, so piping to jq always works.
• TLS certificates are verified by default. For trusted servers with self-signed or private-CA certificates, opt in to relaxed verification with --insecure, ARCQ_INSECURE=1, or "insecure": true in ~/.arcq.json (scoped to arcq's own requests; prints a stderr warning).
• Requests are sent as POST with form-encoded bodies, so the token never appears in a URL.

Agent support

• Ships an installable agent skill at skills/arcq/SKILL.md covering discovery, the where-clause quoting rule, output shaping, the exit-code contract, and TLS behavior.
