The prime-agent switcher existed only as a 275-line string literal inside
prime-agent-extension.ts, so nothing typechecked or linted it — the exact gap
that let a wrong ctx.ui.select() option shape ship in the pi extension. It now
lives at src/prime-agent-ext/mcpctl-switch.ts with a generator, a tsconfig
checking it against the real @earendil-works/pi-coding-agent types, eslint
coverage and an embed-freshness test, matching pi and opencode.
The extraction was verified byte-identical before any edit, so the behaviour
shipped today is exactly what was captured. Linting it then found six problems
in code nothing had ever checked: object-truthiness null guards, a nullable
string conditional and a missing return type. All behaviour-preserving to fix,
but exactly the class of thing that ships silently when nothing is looking.
Also:
- `config pi` gains --dry-run, the last agent without it.
- The SessionStart hook installer now drops untagged duplicates of its own
exact command — rows left behind before the marker existed, or by a suite
that used to write into a real ~/.claude. Invisible in the UI; they just run
the sync twice per session. A hook the user wrote is never touched, even one
calling `mcpctl skills sync` with different flags.
- docs/claude-integration.md and docs/prime-agent-extension.md, the two
integrations that had no page.
prime-agent deliberately keeps its per-project MCP entry name rather than the
constant `mcpctl` claude and opencode now use: its switcher already unmounts the
previous project, so it never accumulates entries, and re-keying auth.json from
mcp:<project> to mcp:mcpctl would give up per-project token caching and needs a
migration. Documented as its own change rather than folded in here.

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.

The pi extension shipped in `src/pi-ext/` was covered by no tsconfig and no
eslint config, so nothing ever checked it against pi's API. Pointing tsc at
the published @earendil-works/pi-coding-agent types found the command surface
to be inert.
Fixes:
- `/mcpctl` did nothing. `ctx.ui.select` takes `string[]` and returns the
chosen string; it was called with `{value,label}` objects, so the menu
rendered five `[object Object]` rows and `choice === "status"` never
matched any branch. Labels are now plain strings mapped back to actions.
- The headless branch returned a status string from a handler typed
`Promise<void>`; pi drops it. Reports via notify instead.
- "Sync skills" omitted `--agent pi`, writing into ~/.claude/skills — in an
integration whose stated purpose is to not depend on ~/.claude — and said
so in its own success message. It also ran execSync with `stdio: "inherit"`,
painting raw output over pi's TUI, and interpolated the project name into a
shell string. Now execFile with `--agent pi` and captured output.
- Tool results typed `content[].type` as `string`; pi's AgentToolResult wants
the `"text"` literal.
- `callTool` asserted `Promise<unknown>` to `ToolCallResult`.
- Sanitising MCP tool names to `[a-z0-9_]` can collide (`docs.search` vs
`docs-search`). The colliding tool was silently never registered but still
reported active, so its calls were forwarded to the first tool. Names are
now disambiguated and tracked with the MCP tool they forward to.
- `registerWithPi` rewrote settings.json even when nothing changed. Since
parsing strips `//` comments, a no-op run destroyed them.
Guards, so this class of bug can't return:
- `src/pi-ext/tsconfig.json` checks the extension against the real published
pi types (dev dependency, not a shim — a shim drifting from the published
API is the exact failure being guarded). Wired into `pnpm typecheck`.
- eslint now covers `src/pi-ext/*.ts` like every other source file.
- A test fails if the embedded copy in `config/pi-extension.ts` is stale;
editing the sources without regenerating silently shipped old code.
Also: the branch added `config pi` without regenerating shell completions
(the committed-completions test was failing), and the doc advertised
`mcpctl pi sync-skills`, which does not exist. Both corrected, plus a note
on the session-token vs `mcpctl_pat_` bearer difference that would bite
against an authenticated `mcplocal serve`.
