fix(agent): clear stale session id when a resumed ACP session is gone [MUL-3216] (#4015)
* fix(agent): clear stale session id when a resumed ACP session is gone When an agent's stored ACP session no longer exists on the runtime side, session/resume still succeeds — hermes echoes the requested sessionId back — so the failure only surfaces when session/prompt returns JSON-RPC -32603 "Session not found". The backend then reported Status=failed with the stale SessionID still set, which kept the daemon's resume-failure fallback (gated on SessionID == "") from ever firing. The failed task never updates the stored session, so every future mention on the same (agent, issue) dispatched against the same dead id, forever (#4010). handleResponse now returns a structured acpRPCError instead of a flat string (rendered text unchanged), and the hermes/kimi/kiro prompt-error paths clear the session id when the error is session-not-found class on a resumed session. The daemon's existing retry then re-executes with a fresh session and stores the replacement id, healing the mapping. * fix(agent): clear stale session id when set_model hits a dead resumed session With a model override, session/set_model runs before session/prompt, so a resumed session that is gone on the agent side surfaces there instead of at the prompt — and the error branch returned the stale SessionID, so the daemon's fresh-session retry (gated on SessionID == "") never fired. Apply the same clear-the-id fix in the set_model error branch of all three backends. Also relax isACPSessionNotFound to accept -32602: kimi-cli raises RequestError.invalid_params({"session_id": "Session not found"}) for every unknown-session path (src/kimi_cli/acp/server.py), so pinning -32603 made the fix dead code for kimi. The wording gate keeps unrelated invalid_params errors (e.g. "model not available") on the preserve-the-id path. Regression tests for all three backends: resumed session + model override + set_model failing with each runtime's observed session-not-found shape must yield status=failed with an empty SessionID. |

MUL-2764 feat(agent): wire mcp_config through ACP runtimes (Hermes / Kimi / Kiro) (#3439)
* MUL-2764 feat(agent): wire mcp_config through ACP runtimes (Hermes / Kimi / Kiro) The MCP config Tab (#3419) already lets admins save mcp_config on an agent, and the daemon plumbs it through to `agent.ExecOptions.McpConfig` for every runtime. Claude and Codex consume it; the three ACP runtimes (Hermes / Kimi / Kiro) ignored the field and hardcoded an empty `mcpServers: []` in their `session/new` requests. Add `buildACPMcpServers` to translate the Claude-style `{"mcpServers": {"<name>": {...}}}` object-of-objects into the array shape ACP requires (`[{name, command, args, env: [{name,value}, ...]}, ...]` for stdio; `[{type, name, url, headers: [...]}, ...]` for http/sse), then pass the translated array on `session/new` (all three) and `session/load` (kiro resume). Malformed JSON fails the launch closed — same contract Codex's `renderCodexMcpServersBlock` uses — so users see a real error instead of silently running with no MCP servers. Individual unclassifiable entries (no command, no url) are skipped with a warning so one bad row can't take MCP down for the rest of the agent. Co-authored-by: multica-agent <github@multica.ai> * MUL-2764 fix(agent): wire mcp_config through ACP resume + gate http/sse on capability Addresses the two blockers Elon raised on #3439: 1. session/resume now carries mcpServers for Hermes and Kimi (Kiro's session/load already did). Per the ACP Session Setup spec the resume path re-attaches MCP servers, and without this a resumed task lost access to MCP tools that a fresh task on the same agent would have had. Pinned with new TestHermesResumeIncludesMcpServers and TestKimiResumeIncludesMcpServers integration tests that inspect the recorded wire request. 2. Added extractACPMcpCapabilities + filterACPMcpServersByCapability so http/sse MCP entries get dropped (with a daemon-log warning naming the entry) when the runtime's initialize response doesn't advertise mcpCapabilities.http / .sse. Sending those entries to a stdio-only runtime is a spec violation and reliably tanks session/new; now they get filtered and the rest of the session still starts. Stdio entries pass through unconditionally. Both backends wire the filter in right after initialize so session/new and session/resume see the same filtered list. Also added TestKiroLoadIncludesMcpServersFromConfig — Elon flagged that no test pinned "non-empty mcp_config actually reaches the wire" for Kimi/Kiro, so the wire assertions go in for all three runtimes.

fix(landing): scope landing route to always-light palette (MUL-1277) (#1537)
* fix(landing): scope landing route to always-light palette The landing page sections use hardcoded light colors (bg-white / #0a0d12), but shared components rendered inside — notably CloudWaitlistExpand on /download — use semantic tokens that flip to dark values under next-themes' `.dark` class, producing a mismatched dark card on an otherwise light page when the user's OS is in dark mode. Add a `.landing-light` class on the landing layout wrapper that re-declares all color tokens to their light values for the subtree, so nested token-driven components stay in lockstep with the hardcoded palette. * test(agent): serialize fake-executable writes to avoid ETXTBSY on CI TestKimiBackendInvokesACPSubcommand (and its Kimi/Codex siblings) write a shell script to a per-test TempDir and then fork/exec it. With t.Parallel() enabled across the package, a concurrent goroutine's fork can inherit the still-open write fd to another test's new executable; Linux then rejects the subsequent exec with ETXTBSY (seen as fork/exec /tmp/.../kimi: text file busy on GitHub Actions). Introduce writeTestExecutable, which holds syscall.ForkLock.RLock across OpenFile→Write→Close. Fork (which takes ForkLock.Lock) cannot run while we hold RLock, so no sibling fork inherits our write fd. Ran the three callers with -count=10 under -p=1 and the full package with no failures. |

feat(agent): add Kimi CLI as agent runtime (#1400)
* feat(agent): add Kimi CLI as agent runtime
Adds support for Moonshot AI's Kimi Code CLI (https://github.com/MoonshotAI/kimi-cli)
as a new agent runtime, alongside Claude, Codex, OpenCode, OpenClaw, Hermes,
Gemini, Pi, Cursor and Copilot.
Kimi Code CLI implements the standard Agent Client Protocol (ACP) via the
`kimi acp` subcommand, so the new `kimiBackend` reuses the existing
hermesClient JSON-RPC transport in the agent package — only the binary,
client identity, log prefix, and tool-name extraction differ.
Wiring:
- server/pkg/agent: new kimiBackend + kimi_test.go; registered in New(),
LaunchHeader map, and the supported-types coverage test.
- server/internal/daemon/config.go: probes `kimi` (overridable via
MULTICA_KIMI_PATH / MULTICA_KIMI_MODEL).
- server/internal/daemon/execenv: writes AGENTS.md as the runtime context
file (Kimi reads AGENTS.md natively via /init), and writes skills under
`.kimi/skills/` so they are auto-discovered by the project-level skill
loader.
- packages/views/runtimes: ProviderLogo gains a Kimi mark.

* feat(agent/kimi): support per-agent model selection via ACP set_model
Wire Kimi into the model dropdown introduced in #1399:
- ListModels gets a 'kimi' case that drives the same ACP
initialize + session/new handshake as Hermes; both share a new
discoverACPModels helper and parseACPSessionNewModels parser
so future ACP backends only need a small provider entry.
- kimiBackend now issues session/set_model after session/new when
opts.Model is non-empty, mirroring the Hermes flow. Failures
fail the task instead of silently falling back to Kimi's
default model — silent fallback would hide that the dropdown
pick wasn't honoured.
Verified: go build ./..., go test ./pkg/agent/... ./internal/daemon/... ./internal/handler/..., pnpm typecheck and pnpm test (138 passed).

* refactor(agent): address code review feedback on Kimi runtime
- Share ACP provider-error sniffer between hermes and kimi. Previously
only hermes promoted stderr-observed 4xx/5xx into a failed task;
kimi would report "completed + empty output" when the Moonshot
upstream rejected a request (expired token, rate limit, …). Rename
hermesProviderErrorSniffer → acpProviderErrorSniffer and parameterise
the provider name; wire it into kimiBackend.Execute the same way.
- Rename extractHermesSessionID → extractACPSessionID (shared by all
ACP backends) so the name matches parseACPSessionNewModels.
- Drop the redundant second argument to kimiToolNameFromTitle; the
Message struct has only one relevant field (Tool), so passing it
twice was a dead fallback. Document that the function normalises
residual capitalised kimi titles not caught by hermesToolNameFromTitle.
- Remove kimi-only cmd.WaitDelay override; the hermes baseline is
fine for both and divergence adds noise.
- Add TestKimiBackendSetModelFailureFailsTask: fake `kimi acp` binary
that returns a JSON-RPC error for session/set_model, asserts that
the task result surfaces status=failed with the model name + upstream
message and preserves the session id.
- Fix stale agent listings in agent.go / daemon/config.go doc comments
(missing cursor, gemini, copilot).
All: `go build ./...`, `go vet ./...`, `go test ./pkg/agent/...
./internal/daemon/... ./internal/handler/...` green.
* fix(agent/kimi): pass --yolo so Shell tools don't hang on approval
Kimi's default config has `default_yolo = false`. Every Shell/file-mutating
tool call causes kimi acp to send a `session/request_permission` request
and block (up to 300s) waiting for a response. The daemon's hermesClient
only handles `session/update` notifications — permission requests go
unanswered, the tool call times out, and the UI loop eventually dies
("UI loop timed out"). Observed with the first real kimi task: agent sat
as Live for ~7 minutes before the daemon killed it.
The fix mirrors hermes' HERMES_YOLO_MODE=1 override: pass `--yolo` to
`kimi` so it auto-approves everything. `--yolo` is a top-level flag on
the `kimi` CLI (not a flag on `kimi acp`), so it must come before the
`acp` subcommand in argv. Added to kimiBlockedArgs so user custom_args
can't strip it.
While here, fix a related bug that made kimi tool names show up empty
in the daemon log ("tool #1: "): hermesToolNameFromTitle's fallback
returned `kind` when neither title-with-colon nor kind matched a known
tool. Kimi's ACP `tool_call` emits bare titles like "Shell" or "Read
file" with no `kind` at all, so we'd drop the title on the floor before
kimiToolNameFromTitle ever got a chance to map it. Now: preserve the
title when kind is unclassified; hermes titles always carry a colon so
this branch never fires for hermes.
Tests:
- TestKimiBackendPassesYoloFlag — fake binary that records its argv,
asserts --yolo comes before acp.
- TestHermesToolNameFromTitle rows for bare kimi-style titles.
- Existing suite green: go build, go vet, full pkg/agent + daemon +
handler test packages.
* fix(agent/acp): auto-approve session/request_permission from agent
The previous attempt (`kimi --yolo acp`) was a no-op. Inspected the
kimi-cli source: the `acp` Typer subcommand takes no parameters, so
flags on the root `kimi` command are dropped before `acp_main()` runs
— it's impossible to opt into YOLO mode through CLI flags for ACP.
The real fix is on our side: respond to session/request_permission.
ACP is bidirectional. When kimi runs a Shell or file-write tool, it
sends `session/request_permission` (agent → client, JSON-RPC request
with id + method) and waits up to 300s for a response. Our existing
hermesClient.handleLine only dispatched: (id + result/error) →
handleResponse, and (no id + method) → handleNotification. A request
with BOTH id and method fell through and got silently dropped — kimi
timed out, UI loop died, task sat stuck for 7 minutes.
Add handleAgentRequest: for session/request_permission, echo the id
and respond with outcome=selected, optionId=approve_for_session. The
daemon is headless; there's no user to prompt. `approve_for_session`
lets the agent remember the action so subsequent identical calls
(every Shell, every file write) skip the round-trip entirely. For any
other agent → client method, reply with standard -32601 method-not-
found so the agent doesn't block.
Also:
- Add writeMu so request() (main goroutine) and handleAgentRequest
(reader goroutine) don't interleave JSON frames on stdin.
- Revert the `--yolo acp` flag — it's a no-op, and carrying it in
kimiBlockedArgs gives the wrong impression that it does something.
Comment in kimi.go now points at handleAgentRequest as the real fix.
Tests:
- TestHermesClientAutoApprovesPermissionRequest: inject a
session/request_permission, assert the reply echoes the id and
carries {outcome: selected, optionId: approve_for_session}.
- TestHermesClientReplesMethodNotFoundForUnknownAgentRequest: confirm
unknown agent → client methods get JSON-RPC -32601 instead of silence.
- TestKimiBackendInvokesACPSubcommand replaces the yolo-flag assertion
with a negative assertion: no dead --yolo / --auto-approve / -y on
argv, since they'd pretend to do something they can't.
All: go build ./..., go vet ./..., go test ./pkg/agent/... green.
* fix(agent/acp): surface kimi tool input/output via content blocks
Kimi-cli emits tool_call and tool_call_update ACP frames with the
input/output inside a `content` array of ContentToolCallContent
blocks (shape: {type:"content", content:{type:"text", text:"..."}}),
not in the hermes-style `rawInput` map / `rawOutput` string. Our
parser only looked at rawInput/rawOutput, so the daemon recorded
empty Input and Output for every kimi tool — the execution-history
UI showed blank terminal panels even for commands that ran fine.
Add extractACPToolCallText() and a fallback in handleToolCallStart /
handleToolCallUpdate: when rawInput is nil / rawOutput is empty, pull
the text out of the content blocks. rawInput / rawOutput still take
precedence so hermes' behaviour is untouched. Terminal /
FileEditToolCallContent blocks are skipped (we have nothing to render
them as — kimi only emits TerminalToolCallContent when the client
advertises terminal capability, which we don't).
Tests:
- TestHermesClientHandleToolCallStartKimiContent — content array →
Input.text populated.
- TestHermesClientHandleToolCallCompleteKimiContent — multi-block
content → Output concatenated with newline separator.
- TestHermesClientHandleToolCallRawOutputTakesPrecedence — hermes
rawOutput still wins when both are present.
- TestExtractACPToolCallText — unit coverage for the helper
(single/multiple text blocks, terminal-block skip, empty input).
* fix(agent/acp): buffer streaming tool args so Input isn't empty in UI
kimi-cli streams tool args token-by-token via tool_call_update frames
— the initial tool_call carries an empty content block and each
subsequent in_progress update carries the cumulative JSON so far
(`{`, `{"comma`, `{"command": "echo`, …). The final completed update
then carries the tool's stdout, not the args. Observed per kimi-cli
acp/session.py::_send_tool_call{,_part,_result} and confirmed by
driving a real Shell call end-to-end: 10 in_progress frames, last
with `{"command": "echo hello world"}`, then completed with `hello
world\n`.
Our previous handleToolCallStart emitted MessageToolUse on the first
tool_call frame, capturing the empty content — so every kimi tool
appeared in the execution-history UI with a blank input. Output was
correct (fix
