Three improvements taken from reading the sibling opencode branches
(feat/opencode-extension-abhishek in particular):
- `<leader>m` opens the project picker. Switching is the repeated action and
typing `/mcpctl` every time is friction; the other two commands stay
palette-only.
- A switch disconnects before re-adding. `mcp.add` under the same name does
re-point the tools on its own, but leaves it to opencode whether the previous
client is closed — and an abandoned one keeps its `mcp-session-id` alive on
mcplocal, which is exactly what holds a gated project open. Best-effort, so a
first mount still works.
- The footer label renders `wrapMode="none" truncate`. The home prompt row is
narrow enough that the default wrap broke `mcpctl:homeautomation` across two
lines mid-word; clipping the tail of a long name reads far better.
Verified against opencode 1.18.15: ctrl-x m opens the picker, the home footer is
now one line, and a disconnect-then-add switch still lands — the model called
`mcpctl_begin_session` and listed the new project's tools.

Adds `mcpctl config opencode`, two opencode plugins and an `opencode` skills
sync target, so an mcpctl project can be switched from inside opencode's TUI
and the active one is visible at a glance.
Unlike `config claude` / `config prime-agent`, this writes NO MCP entry into
the host's config. opencode exposes an HTTP API for its own MCP registry
(`POST /mcp`), so the project is mounted through the running app:
- the token stays in ~/.mcpctl/opencode-state.json (0600) instead of a
mode-0644 opencode.json users paste into bug reports;
- switching projects takes effect on the next turn, with no restart.
Inside opencode:
/mcpctl filterable project picker; switches live
/mcpctl-status active project, mount state, gateway URL
/mcpctl-skills re-sync this project's skills
plus a `mcpctl:<project>` indicator in the prompt footer, next to the model
name and one line above the token counter.
Design notes:
- the MCP server is registered under a constant name, so tools keep a stable
`mcpctl_*` prefix and opencode's per-request tool resolution shows the new
project's tools by itself — no "your old tool names are dead" message to
the model, unlike the pi extension;
- an unchanged mount is never re-registered: mcp.add rebuilds the connection
and mcplocal binds a gated project's unlocked state to that connection's
mcp-session-id, so re-adding would re-lock a project begin_session had just
opened;
- the server plugin does not mount during setup — setup runs before the
server accepts connections and mcp.add calls back into it, which hangs
opencode on a blank screen before the TUI draws;
- the switcher shells out to this CLI (--skip-plugin --skip-marker) so token
minting, state and skills stay in one place;
- no usable credential aborts non-zero with the state file untouched, so a
failed switch leaves the previous project working rather than swapping it
for a mount that 401s.
`skills sync --agent opencode` installs into ~/.config/opencode/skill (XDG
aware) with the same shared-tree semantics as pi and prime-agent. The
credential plumbing shared with `config prime-agent` is lifted to one place and
parameterised by agent rather than copied.
The plugin sources are embedded in the CLI (generated, freshness-tested) so an
installed binary with no source tree can provision them, and are typechecked
against the real @opencode-ai/plugin types.
