* 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.
Active long-running sessions are no longer killed by a fixed wall-clock deadline. Liveness is delegated to the idle watchdog (MULTICA_AGENT_IDLE_WATCHDOG, default 30m) with a larger in-flight-tool budget (MULTICA_AGENT_TOOL_WATCHDOG, default 2h). MULTICA_AGENT_TIMEOUT is an opt-in absolute cap (default 0 = no cap). The server-side 2.5h sweeper is unchanged as a coarse backstop.
Fixes#3745.
* 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.

* 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 Hermes ACP usage attribution to current model when agent.model is unset.
Also preserves cache-read token accounting and makes ACP model-list parsing more tolerant of snake_case payloads and Unknown display names.
`hermes`, `kimi`, and `kiro` all wired stderr through
`cmd.Stderr = io.MultiWriter(logWriter, providerErrSniffer)`.
The OS-pipe → MultiWriter copy goroutine that exec spawns for
that form is only joined by `cmd.Wait()`, which the lifecycle
goroutine fires in deferred cleanup — *after*
`promoteACPResultOnProviderError` already consulted the sniffer.
When stopReason=end_turn (success) raced ahead of the stderr
drain, the sniffer's `lines` slice was empty, the helper fell
through to the synthetic agent-text fallback ("hermes provider
error: API call failed after 3 retries"), and the actionable
upstream signal (HTTP 429 / usage limit) was lost.
This was visible as a flaky
`TestHermesBackendPromotesProviderErrorWithNonEmptyOutput` in CI
under high parallelism — a real prod bug, not a test issue: live
runs hit the same race when an upstream LLM returns 429 and
hermes' synthetic agent turn beats the stderr drain to the
parent.
Replace the MultiWriter wiring with `cmd.StderrPipe()` + an
explicit copier goroutine that signals on `stderrDone`. The
lifecycle goroutine already awaits `<-readerDone` for stdout;
add `<-stderrDone` next to it before `promoteACPResultOnProviderError`
runs. The deferred `cmd.Wait()` ordering is unchanged — it just
becomes a cheap reap by the time it fires.
Verified: `go test ./pkg/agent/ -run "TestHermes|TestKimi|TestKiro"
-count=10 -race`, then full package `-count=3 -race`, all green.

ACP backends (Kiro, Hermes, Kimi) put the actionable reason for
code=-32603 'Internal error' in the JSON-RPC `data` field, e.g.
"No session found with id". The wrapped Go error only carried
`code` and `message`, leaving operators staring at a bare
"kiro session/prompt failed: session/prompt: Internal error
(code=-32603)" with no way to tell apart session expiry, model
unavailability, lost auth, or quota.
Parse `data` too. Strings render unquoted; objects/arrays render
as raw JSON; null/missing keeps the previous format unchanged.

* fix(daemon): mark provider 429 / out-of-credit runs as failed, not completed
Two bugs combined to silently report failed agent runs as
"Completed" in the UI when the upstream LLM returned a 4xx (e.g.
HTTP 429 rate-limit / no credit on the account).
1. ACP backends (hermes, kimi, kiro) only promoted the run status to
"failed" when their stderr sniffer fired AND the agent output
buffer was empty. But hermes injects a synthetic agent text turn
("API call failed after 3 retries: HTTP 429...") on retry
exhaustion, so the buffer was never empty in the rate-limit
case and the promotion never ran. Drop the empty-output
precondition: the sniffer's regex (HTTP-status markers, named
error types) is specific enough to trust on its own.
2. The daemon's task-result switch only routed "blocked" through
FailTask; every other status — including "cancelled", and any
future status we forget to enumerate — fell through to
CompleteTask. Invert it so only an explicit "completed" status
reports success, and extract the switch into reportTaskResult
for direct testing. Cancelled now defaults to failure_reason
"cancelled" instead of being silently completed.
Closes GitHub multica#1952.

* fix(agent): only promote ACP run to failed on terminal provider error
Address GPT-Boy's review on the multica#1952 fix. The previous
promotion rule ("any sniffer line → fail") was too broad: the
existing sniffer also captures transient per-attempt warnings
("API call failed (attempt 1/3): RateLimitError [HTTP 429]"), and
those lines stay in the buffer for the rest of the run. A retry
sequence whose first attempt blipped but whose third attempt
succeeded would have been wrongly reported as failed.
Tighten the criteria with two additional signals, both defined on
the existing acpProviderErrorSniffer / output buffer:
- acpTerminalErrorRe — sticky `terminal` flag set when stderr shows
an exhausted/non-retryable marker (❌, [ERROR], "after N retries",
Non-retryable, BadRequestError, AuthenticationError). Per-attempt
warnings deliberately don't match.
- acpAgentOutputTerminalRe — matches the synthetic "API call failed
after N retries..." turn that hermes-style adapters inject into
the agent text stream when they give up; this catches multica#1952
even if hermes' stderr only logged transient attempts.
Promotion logic becomes a shared helper, promoteACPResultOnProviderError,
called from hermes / kimi / kiro. Promotes when (a) terminalMessage
is non-empty, (b) output contains the synthetic give-up turn, or
(c) output is empty and the sniffer captured anything at all
(preserves the original empty-output safety net for transient-only
sequences with no real result to fall back on).
Tests:
- TestHermesProviderErrorSnifferTerminalVsTransient — transient
attempt 1/3 alone returns terminalMessage="" but message!="";
a follow-on terminal marker flips terminal on.
- TestHermesProviderErrorSnifferTerminalNonRetryable — confirms
BadRequest / Authentication / Non-retryable / ❌ / [ERROR] are
classified terminal even on the very first attempt.
- TestHermesBackendDoesNotPromoteOnTransientRetry — fake hermes
emits attempt 1/3 to stderr then a normal agent text turn and
end_turn; resulting Status must stay "completed".

When the local state.db of an ACP backend (hermes, kimi, kiro) is wiped
— crash, config change, manual kill, container reset — the backend's
session/resume (or session/load, in kiro's case) silently creates a
brand-new session rather than failing, and returns the new id in the
response. Today the daemon ignores the response and stamps
sessionID = opts.ResumeSessionID across all three backends, so every
subsequent session/prompt is addressed to a session id the backend has
no record of. The task fails with JSON-RPC -32603 (Internal error) on
the very first turn, with no operator-visible signal that the problem
is a session-id mismatch one layer down.
The behavior is invisible: agent shows "started", then "failed" with a
generic Internal error. Reproducing in production took repeated runs
because nothing in the logs pointed at the silent reset.
Fix: route all three ACP backends through a small `resolveResumedSessionID`
helper that:
- prefers the id the backend returned in its response (the canonical
id; the one the backend will accept on the next call)
- falls back to the requested id when the response is malformed,
empty, or omits sessionId — defensive fallback so older / non-
conforming backends (notably kiro's current session/load shape)
behave identically to today
- signals (via a bool) when the id changed, so the caller logs a Warn
with `backend=<hermes|kimi|kiro>` and operators can grep for silent
state resets to correlate them with task failures
Why this is at the backend layer rather than the daemon's existing
session-resume fallback: server/internal/daemon/daemon.go:1554-1566
already retries with a fresh session when resume fails, but it gates
on `result.Status == "failed" && result.SessionID == ""`. The backend
WILL hand back a result.SessionID — just the new one it silently
committed to — so the daemon-level fallback never fires for this
failure mode.
The helper is also what session/new already uses (extractACPSessionID,
documented in code as "Shared by all ACP backends"). session/new
extracts the canonical id from the response; session/resume just
didn't, until now.
Coverage:
- hermes.go: confirmed bug, root cause of -32603 in production
- kimi.go: same code shape, same protocol method, same response
schema as hermes (per extractACPSessionID's comment) — same bug
- kiro.go: same code shape, different method (session/load). Current
observed response doesn't include sessionId, so the defensive
fallback means today's behavior is preserved. Routing through the
same helper means a future kiro release that DOES return a sessionId
on silent reset works the same way as hermes/kimi without another
diff.
Tests (server/pkg/agent/hermes_test.go — helper covers all three
backends, no per-backend duplication):
- TestResolveResumedSessionIDMatching — backend confirms requested id
- TestResolveResumedSessionIDDifferent — backend returned a new id;
caller is told to switch
- TestResolveResumedSessionIDEmptyResponse — older / malformed body;
defensive fallback to requested id (covers kiro's current shape)

Hermes ACP can flush queued session updates from the previous turn
before the current turn actually starts — both as session/resume
history replay and as chunks queued before our session/prompt response
streams. Without a gate those updates were appended to output and
re-emitted to the UI, so the previous answer appeared duplicated next
to the new one. Closes#1997.
PR #1789 added the acceptNotification hook field to hermesClient and
the call site in handleNotification, but never assigned it for Hermes,
so the guard short-circuited and every notification was processed.
This change mirrors the working Kiro pattern (kiro.go:87/97/240):
- declare a streamingCurrentTurn atomic.Bool in the backend.
- assign acceptNotification, onMessage, onPromptDone gates that all
return early when the flag is false.
- flip the flag to true immediately before c.request("session/prompt").
Adds TestHermesClientAcceptNotificationGate as a regression test that
exercises the gate directly on hermesClient.
Verified with `go test ./pkg/agent`.

* fix(hermes): drop false native-skill claim and add regression tests
The previous change added 'hermes' to the 'skills discovered automatically'
branch of buildMetaSkillContent, but resolveSkillsDir has no Hermes case so
skills still land in the .agent_context/skills/ fallback. AGENTS.md ended up
claiming native discovery while the files were somewhere else, which would
mislead Hermes (and future debuggers).
- Move 'hermes' to the fallback branch alongside 'gemini' so AGENTS.md points
Hermes at .agent_context/skills/ — matching where writeContextFiles actually
writes them.
- Extract buildHermesSessionParams so the session/new payload is unit-testable.
- Add regression tests covering:
* buildHermesSessionParams includes/omits 'model' correctly
* InjectRuntimeConfig('hermes') writes AGENTS.md with the fallback hint
* writeContextFiles('hermes') writes skills to .agent_context/skills/

Surface the actual exec path + argv for every agent backend at INFO
so operators can see the exact command without flipping to debug.
Also add the missing log line in pi.go for consistency with the
other nine backends.
* 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 4335c198) but command was missing.
Changes:
- hermesClient now tracks pending tool calls per toolCallId. Hermes
path is unchanged — rawInput is present at tool_call time, so
emit-immediately-then-flag-emitted still fires on the initial frame.
- kimi path defers MessageToolUse until status=completed / failed.
tool_call_update in_progress frames update the buffered argsText
(cumulative, so overwrite); on completion we parse the accumulated
JSON into Message.Input. Malformed JSON falls back to `{"text": …}`
so non-JSON tool args still render.
- Orphan completion frames (no matching tool_call seen — e.g. daemon
restarted mid-task) synthesise ToolUse from the update's own
title/kind/rawInput so the UI still gets a header.
- extractACPToolCallText now also renders FileEditToolCallContent
blocks as a compact header ("--- path / +++ path / (edited: N → M
bytes)"). kimi emits these for Write / StrReplaceFile / Patch when
the tool's display block is a DiffDisplayBlock.
Tests:
- TestHermesClientKimiStreamingToolCall: empty tool_call + 5 streaming
in_progress + completed. Asserts no emission until complete, then
[ToolUse(Input.command="echo hi"), ToolResult(Output="hi\n")].
- TestHermesClientKimiMalformedArgsFallback: non-JSON argsText → falls
back to Input.text.
- TestHermesClientHandleToolCallCompleteOrphan: completed frame
without a start → ToolUse synthesised from update's rawInput.
- TestExtractACPToolCallText: diff + new-file-diff cases.
All agent / daemon / handler test packages green.

Adds a first-class `model` field on agents so users can pick the LLM model from the create / settings UI instead of editing `custom_env` / `custom_args`. Each provider's dropdown is populated from the live CLI when possible (`opencode models`, `pi --list-models`, `openclaw agents list --json`, `cursor-agent --list-models`, hermes ACP `session/new` → `SessionModelState`), with a static catalog for providers that don't enumerate.
Daemon resolves the runtime model as `agent.model → MULTICA_<PROVIDER>_MODEL → ""` — empty passes through so each backend's CLI picks its own default, avoiding static-guess drift.
Per-provider honouring:
- Claude / Codex / OpenCode / Cursor / Gemini / Pi / Copilot — CLI `--model` / thread payload.
- OpenClaw — `opts.Model` is mapped to `--agent <name>` (the CLI rejects `--model`).
- Hermes — `session/set_model` ACP RPC; stderr is sniffed for provider-level errors so HTTP 4xx from the configured LLM surfaces instead of "empty output"; explicit-model failures mark the task `failed`.
Supporting changes: migration 050 adds `agent.model`; daemon ↔ server heartbeat piggyback carries a model-discovery request; new REST endpoints under `/api/runtimes/{id}/models`; `multica agent create --model` / `update --model`; shared `ModelDropdown` in `packages/views/agents` (searchable, creatable, provider-grouped, default-badge, runtime-supported gate).
Every other backend (claude, codex, opencode, openclaw, gemini) filters
opts.CustomArgs through a per-backend blocked map so protocol-critical
flags can't be overridden via the Create Agent UI. The hermes backend
appended CustomArgs directly to argv, so any future flag we add to the
map would be silently bypassed here.
Add hermesBlockedArgs (with 'acp' as the pinned subcommand) and route
CustomArgs through filterCustomArgs. Behaviour is identical for today's
use cases; the change prevents accidental protocol-flag overrides and
brings hermes in line with the other five backends.

Add a debug-level log line in every agent backend (claude, codex,
opencode, openclaw, gemini, hermes) that prints the executable path
and full argument list when spawning the agent process. Helps diagnose
custom args, model overrides, and other CLI flag issues.
* feat(agent): add custom CLI arguments support
Allow users to configure custom CLI arguments per agent that get
appended to the agent subprocess command at launch time. This enables
use cases like specifying different models (--model o3), max turns,
or other provider-specific flags without needing separate runtimes.
Changes:
- Add custom_args JSONB column to agent table (migration 041)
- Update API handler to accept/return custom_args in create/update
- Pass custom_args through claim endpoint to daemon
- Append custom_args to CLI commands for all agent backends
- Add ExecOptions.CustomArgs field in agent package
- Add Custom Args tab in agent detail UI
- Add --custom-args flag to CLI agent create/update commands
Closes MUL-802
* fix(agent): filter protocol-critical flags from custom_args
Add per-backend filtering of custom_args to prevent users from
accidentally overriding flags that the daemon hardcodes for its
communication protocol (e.g. --output-format, --input-format,
--permission-mode for Claude).
This follows the same pattern as custom_env's isBlockedEnvKey: we
only block the small, stable set of flags that would break the
daemon↔agent protocol — not every possible dangerous flag. Workspace
members are trusted for everything else.
Each backend defines its own blocked set:
- Claude: -p, --output-format, --input-format, --permission-mode
- Gemini: -p, --yolo, -o
- Codex: --listen
- OpenCode: --format
- OpenClaw: --local, --json, --session-id, --message
- Hermes: none (ACP is positional)
Includes unit tests for the filtering logic.
* fix(agent): address code review nits for custom_args
- Replace module-level `nextArgId` counter with `crypto.randomUUID()`
in custom-args-tab.tsx to avoid SSR ID conflicts
- Add unit tests for custom args passthrough and blocked-arg filtering
in both Claude and Gemini arg builders
* feat(agent): add Hermes Agent Provider via ACP protocol
Integrate Hermes as a new agent backend using the ACP (Agent
Communication Protocol) JSON-RPC 2.0 over stdio — the same pattern
as the Codex provider but with ACP-specific methods.
- New hermesBackend spawns `hermes acp` and drives initialize →
session/new → session/prompt lifecycle
- Handles session/update notifications: agent_message_chunk,
agent_thought_chunk, tool_call, tool_call_update, usage_update
- Auto-approves tool executions via HERMES_YOLO_MODE env var
- Supports session resume, model override, system prompt injection
- Token usage extracted from PromptResponse and usage_update events
- Auto-detected at daemon startup via MULTICA_HERMES_PATH env var

* feat(ui): optimize runtime icons and fix create-agent dialog overflow
- Replace OpenClaw pixel-art icon (32 rects) with clean vector paths
- Add Hermes provider icon (NousResearch mascot, 48x48 webp data URI)
- Use provider-specific icons in runtime selector instead of generic Monitor
- Fix dialog overflow: add min-w-0 to grid item so truncate works

* fix(agent): add required mcpServers param to Hermes ACP session/new
ACP SDK v0.11.2 requires mcpServers as a mandatory field in
NewSessionRequest. Without it, Pydantic validation fails with
"Invalid params" and the agent immediately errors out.
