1.0.85: CLI parser rewrite and copilot plugins flag removals (breaking). Command-line parsing moved from Commander to a Rust grammar; error and help wording changed (L141). copilot plugins install --skill [--scope project] is replaced by copilot skill add [--project] (L149). The cross-kind --kind, --scope, --mcp, --skill flags on copilot plugins are gone (L150). copilot plugins list --json now emits a flat array instead of { plugins, errors } (L151). New copilot mcp / copilot skill enable/disable subcommands (L49).
Channel: tagged-release. Half: both. Date: 2026-09-16.
Operator consequence: Adapt: scripts that parse copilot plugins list --json or install skills via plugins install --skill break on 1.0.85. Grep provisioning scripts before upgrading a fleet. Scripts that match CLI error text also need a recheck.
