0.9: Trail, one settings shape, setup as skills

[Codestz]

0.9.0 — Trail, one settings shape, setup as skills. Merged with a merge commit to keep the history.

What 0.9 is

Trail — a new bay (@opencode-cockpit/trail). The agent records what a conversation creates or changes outside the repo — PRs, tickets, doc pages, deploys — with trail_add; Cockpit keeps, groups (by ticket, with for) and shows it: a sidebar block, /trail (this conversation / all conversations in the project, search, open, go to the conversation, copy, markdown), /link to add one by hand, and trail_list so any conversation can answer "what did we ship for COM-1736?". Guidance in the system prompt plus a one-line reminder when a command's output holds a PR link not yet recorded; the agent decides.

One settings shape. One JSONC loader (comments and trailing commas no longer drop the file), one section per bay, the same shared keys everywhere (enabled, keybinds, sidebar, sidebarRows, hideWhenEmpty), one sidebar order list. Old names are not read: each shows a ! notice pointing to /cockpit-setup.

Setup as skills. /cockpit-setup and /status-setup load shipped skills; cockpit_settings reads the live state (bays, values and where they came from, notices, OpenCode's own sidebar blocks per version); an opt-in second phase tunes Cockpit to the project and writes one marked ## Cockpit conventions section in AGENTS.md (cockpit_conventions).

Status. The sidebar table is the default (spend/avail/git built in); override changes a row by name without copying the preset; git counts uncommitted work; diagnostics in the table; preview reads a config on stdin.

Fixes and the rest. #34 (diagnostics flagged every MCP server on OpenCode 2); Review renders image diffs (metadata, pixel diff, half-block preview, o opens both); blocks say none yet when empty; subagent rows line up and name their agent; Shell's "show fewer"; OpenCode 2's background service keeps old plugin code — dev:install restarts it, doctor and update say so; per-bay guidance tightened and measured with real agent turns (AGENT=1 smoke).

Full list: CHANGELOG.md, Unreleased.

Also in

• Trail without automatic tracking: the agent records, /link adds by hand, a reminder line nudges.
• Default keys that no longer shadow OpenCode's own (ctrl+x d/j/k), the same on both versions.
• A toast when OpenCode 2's background service runs an older Cockpit than the window; setup's final check includes each bay's own validation.
• Refactors (client/src/setup.ts 925 → 51 lines + setup/; Trail's interface split; one JSONC parser, one bay list, one link opener), checked against a byte-for-byte baseline of 60 preview renders.
• Docs synced (README, site, package READMEs); a real Trail recording; Dependabot Bump @opencode-ai/plugin from 1.18.31 to 1.18.33 in the opencode group across 1 directory #28–Bump @babel/core from 7.28.0 to 7.29.7 #30 applied.

Checks so far

bun run check (2170 pass), pack:check (Trail included), AGENT=1 bun run smoke:tui on OpenCode 1.18.32 and 2.0.18 (behaviour measured with real agent turns), CI on macOS and Linux, and a live check by the maintainer on the final install.
