x9 Agent Skills v3.2.0

Highlights

• x9-idea-critic now uses provider-level claude and gpt routes with centralized model defaults: the official fable alias and GPT-6 Astra, both at high effort, across Claude Code, Codex, and OpenCode.
• x9-browser-session hardens its verified Edge adapter by binding remote debugging to localhost, moving it to port 9223, checking that the endpoint belongs to the expected automation profile, and preserving authenticated profile state without isolated browser contexts.
• x9-agent-instructions now preserves scope-critical user wording in continuation briefs and retains targeted behavioral guidance only when observed failures or current model documentation support it.
• Shared global instructions now require current primary evidence for fast-changing technical claims, batch independent read-only work, favor direct execution, and inherit the primary model for substantive Codex/OpenCode delegation.
• x9-opencode-sessions now finds the standard per-user OpenCode V2 installation when automation runs with a minimal PATH.

Install / update

• Existing users of the documented Edge adapter must update the launcher, MCP endpoints, and agent-edge wrapper from port 9222 to 9223; the wrapper now also verifies the owning browser process and profile.
• x9-idea-critic requires Claude CLI with Fable access in all three runtimes. OpenCode users also need the documented general-purpose astra-high subagent; the skill does not modify local configuration automatically.
• Codex/OpenCode users adopting model inheritance should remove lower-cost subagent defaults from their local configuration; the published instructions do not change runtime model settings automatically.

Compatibility

• x9-idea-critic retains the gpt mode. Official Claude aliases follow the service's current target, and every Claude CLI result must identify the selected critic model.
• OpenCode session inspection no longer depends on shell startup files exposing ~/.local/bin.
• x9-agent-instructions regression tests now resolve repository files correctly when launched through an installed skill symlink.
• Obsolete maintainer planning and audit snapshots were removed; no shipped skill or installation artifact depends on them.

Breaking changes

• x9-idea-critic replaces the model-specific opus mode with the provider-level claude mode. Its Claude Code Claude route now requires Claude CLI instead of optionally using a native Opus agent.
• The documented Edge adapter now uses CDP port 9223; installations copied from the previous 9222 recipe must update the launcher, MCP configuration, and agent-edge wrapper together.
