CHANGELOG.md

Changelog

Repo: https://github.com/openclaw/acpx

Unreleased

Changes

• Docs/readme: rewrite the project front door to the house standard and route detailed CLI guidance to the existing documentation.

• Runtime/embedding: expose the existing per-tool permission policy through AcpRuntimeOptions so embedded clients can reuse its rule matching and decisions. Thanks @xenaocx-dev.

Breaking

• Runtime API: require AcpRuntimeTurn.promptStarted, which settles after connection.prompt() returns its request promise or fails beforehand.

Fixes

• Runtime/embedding: settle turn results only after lifecycle persistence and client cleanup attempts finish, including unexpected finalization failures.
• Replay viewer: contain manifest-selected projection reads within their run bundle, including symlink targets. Thanks @bunlongheng.
• CLI/session: re-apply a session-pinned model before set_mode/set_model/set_config_option after reconnect, matching the prompt path so model-dependent options work. Fixes #489. Thanks @SebTardif.
• Runtime: preserve non-empty messageId and a safe subset of ACP update _meta on text_delta events so consumers can distinguish model prose from adapter diagnostics that still use agent_message_chunk. Thanks @SebTardif.
• Runtime/sessions: keep atomic-write temporary filenames within filesystem component limits when valid session IDs have long basenames. Thanks @henkterharmsel.
• Runtime/embedding: snapshot permission policies at client configuration boundaries so caller-side mutation cannot change an in-flight turn after prompt readiness.
• Replay viewer: return the same not-found response for missing files and containment-denied paths, preventing outside-target existence probes.
• Runtime/sessions: surface checkpoint flush and session-store save failures during turn finalization instead of dropping them. Thanks @SebTardif.
• ACP/terminal: time out hung ps / PowerShell process-list helpers after a shell-backed terminal exits so wait_for_exit, kill, and release can finish. Thanks @SebTardif.
• ACP/terminal: raise the process-list helper stdout cap above execFile's 1 MiB default so large ps listings are not dropped as empty. Thanks @SebTardif.
• Runtime/embedding: retain one-shot session ownership from initialization through its turn so repeated pre-turn ensureSession calls reuse one backend session, then clean it up after completion. Fixes #504. Thanks @jhgaylor.
• Runtime/embedding: project and persist session/update notifications for the full lifetime of retained sessions, including idle periods before and between turns. Fixes #477. Thanks @nyl199310.

2026.7.27 (v0.13.0)

Highlights

• Windows agent launches now use structured argv end to end. Unambiguous legacy command plus args entries migrate automatically; ambiguous/raw commands and .sh wrappers must move to agents.<name>.argv, and existing saved custom-agent sessions without argv must be recreated.
• Built-in Pool and ZeroClaw support makes both native ACP stdio servers available without custom registry configuration.
• The new --no-fs flag lets compatible agents use their native filesystem implementation instead of ACP client filesystem methods.
• The dependency and pnpm refresh resolves all four known PostCSS, fast-uri, js-yaml, and brace-expansion advisories.

Changes

• Agents/built-ins: add Pool via pool acp. Thanks @dan-roberts-poolside and @osolmaz.

• Agents/built-ins: add ZeroClaw via zeroclaw acp, ZeroClaw's native ACP v1 stdio server. Thanks @JordanTheJet.

• CLI/ACP: add --no-fs to disable advertised ACP file read/write capabilities so compatible agents can use their native filesystem implementation. Thanks @zgxkbtl.

• CLI/timers: preserve tiny positive timeout and TTL values from flags or config as 1 ms instead of disabling timers, and reject delays beyond Node's supported timer range. Thanks @realmehmetali.

• Dependencies/tooling: refresh the ACP SDK, runtime and development toolchain, update pnpm to 10.34.5, and resolve the PostCSS, fast-uri, js-yaml, and brace-expansion advisories.

Breaking

• Windows agent launches now require structured agents.<name>.argv; unambiguous legacy command plus args entries migrate automatically, while raw, ambiguous, or directly executable .sh commands fail with explicit migration guidance instead of lossy parsing or CreateProcess ENOENT. Existing custom-agent sessions without saved argv must be recreated. Fixes #466. Thanks @MarcelCFritsche.

Fixes

• Flows: swallow best-effort heartbeat write failures at the timer boundary so storage errors do not become unhandled promise rejections. Thanks @SebTardif.

• Runtime/sessions: use collision-resistant temporary paths for concurrent atomic session and index writes. Thanks @henkterharmsel.

• CLI/status: report a normal cold-start session as agent starting while preserving needs reconnect for an unreachable live owner. Thanks @guettli.

2026.7.23 (v0.12.1)

Changes

• Agents/built-ins: refresh the default Pi, Codex, Claude, and Mux adapter ranges. Thanks @kelvinschen and @TheAngryPit.

Breaking

Fixes

• Session queue owner: capture a bounded owner stderr tail and exit status during cold start only (stop retaining at first IPC accept; keep draining the pipe so long-lived owners are not killed by EPIPE) so a dead owner reports the real failure instead of a silent timeout. Thanks @SebTardif.

2026.7.4 (v0.12.0)

Changes

• Agents/built-ins: add Grok Build via grok agent stdio, including cached-login and XAI_API_KEY authentication selection. Thanks @TheAngryPit.

Breaking

Fixes

• CLI/queue: drain active turns before releasing queue-owner leases and preserve typed retryable shutdown responses while terminating agent bridges. Thanks @superWorldSavior.

• CLI/quiet output: emit exactly one structured stderr diagnostic for direct and queued prompt failures without adding diagnostics to stdout. Thanks @superWorldSavior.

2026.6.23 (v0.11.2)

Changes

Breaking

Fixes

• Runtime/status: persist token usage reported on successful prompt responses, including adapters that only provide a sparse usage_update.

2026.6.23 (v0.11.1)

Changes

• Runtime/embedding: preserve per-agent environment variables across ACP session creation, queue handoff, persistence, and reconnects. Thanks @zhangguiping-xydt.

Breaking

Fixes

• CLI/queue: harden command parsing, queue-owner startup, stale process cleanup, and release/CI checks found by clawpatch.
• Windows/Claude: only export a native .exe as CLAUDE_CODE_EXECUTABLE; unresolved .cmd, .bat, and .ps1 shims now fall back to the Claude ACP adapter's bundled native binary. Fixes openclaw/openclaw#93465.
• Client/ACP: ignore non-object JSON lines from adapter stdout before ACP dispatch, preventing primitive frames from crashing the SDK message path.
• ACP/models: call the current SDK session/set_model method for legacy model metadata instead of the generic extension fallback.
• CLI/config: add --mcp-config for session-scoped MCP servers without writing a project config file. Live persistent sessions reject MCP config changes until closed. Fixes #387.

2026.6.17 (v0.11.0)

Changes

• Agents/built-ins: bump the default Claude ACP adapter range to @agentclientprotocol/claude-agent-acp@^0.37.0. Thanks @trumpyla.
• Runtime/embedding: surface cost, token usage breakdowns, and advertised command metadata on runtime status/events. Thanks @DaniAkash.
• Agents/built-ins: add fast-agent as a built-in fast-agent ACP adapter via uvx fast-agent-mcp acp.
• Agents/built-ins: add mux as a built-in coder/mux ACP adapter via npx -y mux@^0.27.0 acp. Thanks @ThomasK33.
• CLI: add acpx compare to run one prompt across multiple agents and summarize timing, token usage, stop reason, permissions, and final output side by side. Thanks @mvanhorn.

Breaking

Fixes

• Runtime/embedding: export a stable typed error and predicate for requested model selectors that an ACP agent does not support, including whether model capability is missing or the requested id is unadvertised, so embedders do not need to match error text.
• CLI/Claude: isolate built-in Claude ACP sessions from user settings by default so globally enabled channel and daemon plugins cannot interfere with a spawned session. Set ACPX_CLAUDE_INCLUDE_USER_SETTINGS=1 to restore user settings deliberately. Fixes #361.
• ACP/models: support SDK 0.25 model config options while preserving session/set_model compatibility for adapters that explicitly advertise legacy model metadata.
• CLI/Claude: let Claude Code adjudicate model selectors missing from a stale advertised model list on later persistent turns, and preserve the adapter-reported current model after model switches. Thanks @oakif.
• Client/ACP: advertise scoped Devin/Windsurf-compatible client metadata and handle Devin extension requests/notifications without noisy method-not-found logs. Thanks @LivioGama.
• Runtime/sessions: treat corrupt public file-session records as missing while preserving genuine filesystem errors. Thanks @KrasimirKralev.

2026.5.23 (v0.10.0)

Changes

• CLI/sessions: add sessions export and sessions import for moving portable session archives between machines. Thanks @mvanhorn.

Breaking

Fixes

2026.5.22 (v0.9.0)

Changes

• Tooling: add Slophammer TypeScript quality gates for coverage, complexity, unsafe types, mutation testing, DRY checks, and dependency boundaries.
• Agents/built-ins: switch the default Codex adapter to @agentclientprotocol/codex-acp, with Codex model selection handled through advertised ACP model ids, and bump the default Claude ACP adapter range.
• Tooling: add a repo-local autoreview skill and helper for Codex-first closeout review with acpx checks in parallel.

Breaking

Fixes

• CLI: treat --version after -- as prompt text instead of intercepting it as a top-level version request.
• CLI: keep custom raw agent commands routed correctly when global flags such as --system-prompt, --append-system-prompt, --prompt-retries, or --no-terminal appear before the agent name. Thanks @amknight.
• CLI/API: avoid installing CLI-only process handlers when the package entrypoint is imported as a module.
• CLI/sessions: use agent-side ACP session/list when available, including cursor pagination, cwd filtering, and agent-native session metadata. Thanks @amknight.
• Sessions/reconnect: use ACP session/resume when adapters advertise it, so resume-only agents can reuse saved sessions without requiring session/load. Thanks @amknight.
• CLI/ACP: validate rich prompt blocks against advertised ACP promptCapabilities and support audio prompt content end-to-end. Thanks @amknight.
• CLI/status: hide stale cached session PIDs when no live helper process exists. Thanks @dutifulbob.

2026.5.15 (v0.8.0)

Changes

• Runtime/embedding: add an optional onPermissionRequest callback to AcpRuntimeOptions and AcpClientOptions so embedders can intercept ACP per-call permission requests with their own UI. Returning a decision short-circuits the mode-based resolver; returning undefined falls through to it, leaving CLI behavior unchanged. Thanks @DaniAkash.
• Runtime/embedding: AcpRuntime.ensureSession now accepts sessionOptions (systemPrompt, model, allowedTools, maxTurns) for fresh sessions, threading the values into _meta.systemPrompt (and _meta.claudeCode.options.*) on the underlying session/new request and persisting them onto the new record. Reusing an existing persistent record continues to ignore sessionOptions since system prompts are fixed at newSession time. SessionAgentOptions and SystemPromptOption are now re-exported from acpx/runtime. Thanks @DaniAkash.
• Runtime/embedding: surface advertised models on AcpRuntimeStatus.models so embedders can build model pickers without reaching into private session records. Thanks @DaniAkash.
• CLI/permissions: add --permission-policy/--policy for per-tool ACP permission rules with autoApprove, autoDeny, escalate, and defaultAction; non-interactive escalations now surface structured tool name/input metadata for orchestrators.

Breaking

Fixes

• Runtime/embedding: preserve structured ACP tool_call_update details on public runtime events, including content, output, locations, kind, and raw payload fields, so embedders can display live tool progress. (#306) Thanks @joeia26.
• CLI/sessions: checkpoint live assistant and tool updates while prompt turns are still running, so sessions read and sessions history can show in-flight progress instead of only the submitted prompt. (#314) Thanks @AndroidPoet.
• Flows: keep external TypeScript flow modules that import acpx/flows compatible with current tsx loader behavior.
• Terminal: run no-argument terminal/create command lines so agents that send an unsplit command do not fail with ENOENT. Thanks @xdjyxu.
• CLI/config: accept command-local --format on config show and config init.
• CLI/sessions: accept the documented -s shorthand on sessions new and sessions ensure.
• Replay viewer: add help output for pnpm viewer --help without starting a server.
• Replay viewer: make pnpm viewer status and pnpm viewer stop dispatch to the requested command instead of always prepending start.
• Package: keep npm pack --json output parseable by running the prepack build quietly.
• CLI/output: exit cleanly on broken pipes so common pipelines such as acpx ... | grep -q ... do not crash with an unhandled EPIPE.
• Tooling: document the current Node.js 22.13+ and pnpm 10.33.2 floor.
• Tooling/docs: document npm-based pnpm bootstrap for clean Node 22.13 setups with stale Corepack signing keys.
• Docs/auth: document the supported authPolicy values and ACP credential selection behavior.
• Docs/skills: make the quick setup skill-install command noninteractive and route unsupported harnesses to the reference URL.
• CLI/queue: honor per-request --prompt-retries when sending a prompt to an already-warm persistent queue owner.
• Runtime/embedding: reject unsupported advertised config option keys before forwarding them to adapters, and map generic thinking controls to advertised effort options when available. (#293)

2026.5.5 (v0.7.0)

Changes

• Flows/authoring: add decision() and decisionEdge() helpers for constrained LLM branching on top of the existing acp, parse, and switch machinery. (#278) Thanks @JoshuaLelon.

Breaking

Fixes

• Runtime/embedding: preserve normalized ACP detailCode values on failed turn results and legacy error events, so embedders can branch on stable error detail codes. (#288) Thanks @kunchenguid.
• Runtime/config: persist advertised configOptions from session/new and session/load and expose their keys through handle-aware runtime capabilities. (#282) Thanks @samithaj.
• CLI/queue: ask active queue owners to send ACP session/close before sessions close terminates their adapter process. (#283) Thanks @codefromthecrypt.
• CLI/models: fail clearly when --model targets a non-Claude ACP agent that does not advertise ACP model support, and reject model ids outside an adapter's advertised availableModels instead of silently falling back to the adapter default.
• Windows/Claude: resolve the claude.exe executable from PATH before spawning Claude ACP sessions, so native Windows launches do not depend on shell-specific command lookup. (#289) Thanks @MikeChongCan.
• Client/ACP: send session/close from closeSession() instead of the experimental nes/close method, so adapters without NES support can tear down sessions cleanly. (#291) Thanks @hexsprite.
• Runtime/WSL: recognize Windows .cmd and .bat ACP agent wrappers for cwd translation, including wrappers installed on non-C drives. (#280) Thanks @solomonneas.

2026.4.25 (v0.6.0)

Changes

• CLI/claude: add --system-prompt <text> and --append-system-prompt <text> global flags that forward through ACP _meta.systemPrompt on session/new, letting callers replace or append to the Claude Code system prompt without dropping out of persistent acpx sessions. The value is persisted in session_options.system_prompt so ensure/reuse flows keep the override. Codex and other agents ignore the field. (#229) Thanks @Vercantez.
• CLI/sessions: add sessions prune with --dry-run, age filters, and --include-history so closed session records and optional event streams can be cleaned up explicitly. (#227) Thanks @coder999999999.
• Runtime/embedding: add startTurn(...) turn handles so embedders can observe live runtime events separately from terminal completion, cancel a turn, or close only the event stream while preserving runTurn(...) compatibility. (#262) Thanks @enki.
• CLI/ACP: add --no-terminal to disable advertised ACP terminal capability for new agent clients. (#155) Thanks @DMQ.
• Agents/built-ins: bump the default @agentclientprotocol/claude-agent-acp, @zed-industries/codex-acp, and pi-acp package ranges so fresh built-in launches pick up the latest adapter releases. (#253, #275) Thanks @flowforgelab.
• Conformance/ACP: add a post-success drain case that catches late tool updates emitted after session/prompt resolves. (#252) Thanks @logofet85-ai.
• Docs/session identity: clarify when CLI output shows ACPX runtime session IDs versus backend agent session IDs.
• Dependencies/CI: update ACP SDK, runtime dependencies, TypeScript-native tooling, formatter/lint tooling, and workflow actions.

Breaking

Fixes

• CLI/runtime: persist non-mode session/set_config_option values and replay them on fresh adapter sessions, so options such as Codex reasoning_effort survive session fallback/reuse. (#138)
• CLI/prompt: honor --model when sending prompts to existing persistent sessions, including queued owner paths. (#211) Thanks @skywills.
• Runtime/persistent sessions: keep reusable persistent ACP clients warm across turns and close pooled clients during runtime close. (#265) Thanks @Sway-Chan.
• Runtime/ACP: drain late post-success session updates before closing prompt turns so adapters that resolve session/prompt before final updates do not drop assistant output. (#251) Thanks @logofet85-ai.
• Runtime/embedding: reuse the saved persistent session when sending runtime controls instead of creating a new backend session for control operations.
• CLI/sessions: persist the submitted prompt at turn start so sessions history and sessions read no longer report No history while an active prompt is already running. (#157)
• Runtime/WSL: translate session cwd with wslpath when running under WSL and spawning Windows .exe ACP agents, so session/new and session/load receive paths the agent can access. (#232)
• Client/auth: require explicit ACPX_AUTH_* env vars or config auth entries for ACP auth-method selection, so ambient provider env like OPENAI_API_KEY no longer triggers unintended login flows in adapters such as codex-acp.
• Config/agents: honor custom agent args arrays from config instead of silently dropping required adapter subcommands. (#199) Thanks @log-li.
• CLI/queue: tighten persistent queue and IPC socket directories to owner-only permissions, including previously-created permissive directories. (#216) Thanks @garagon.
• CLI/queue: use cryptographically random owner generation IDs so rapid queue owner restarts cannot reuse a stale generation token. (#207) Thanks @Yuan-ManX.
• Output/errors: add text-mode remediation hints for auth-required, missing-session, ACP session failures, timeouts, provider rate limits, and invalid model names while keeping JSON error payloads stable. (#256) Thanks @SJeffZhang.
• CLI/quiet output: emit final token usage and cost metadata to stderr when adapters include it in the ACP prompt result, while keeping quiet stdout as assistant text only. (#257)
• CLI/status: report resumable persistent sessions as idle when no queue owner is running, instead of marking pre-prompt or TTL-expired sessions as dead. (#185)
• Client/ACP: use the locked ACP SDK close API path so session closing stays compatible with the current SDK.
• Runtime/doctor: guarantee doctor().details contains strings even when probe failures include Error or object values. (#267)
• Replay viewer: protect run-bundle file reads from run-id boundary escapes.

2026.4.8 (v0.5.3)

Breaking

Fixes

2026.4.4 (v0.4.1)

Changes

• Flows/workflows: add an initial flow run command, an acpx/flows runtime surface, and file-backed flow run state under ~/.acpx/flows/runs for user-authored workflow modules. (#179) Thanks @osolmaz.
• Flows/replay: store flow runs as trace bundles with manifest.json, flow.json, trace.ndjson, projections, bundled session replay data, and per-attempt ACP/action receipts for later inspection. (#181) Thanks @osolmaz.
• Flows/replay viewer: add a React Flow-based replay viewer example that replays saved run bundles and shows the bundled ACP session beside the graph. (#183) Thanks @osolmaz.
• Flows/permissions: let flows declare explicit required permission modes, fail fast when a flow requires an explicit --approve-all grant, and preserve the granted mode through persistent ACP queue-owner paths. (#186) Thanks @osolmaz.
• Flows/workspaces: let ACP validation choose PR test plans and broaden PR-triage refactor judgment. (#189, #190) Thanks @osolmaz.

• CLI/prompts: add --prompt-retries to retry transient prompt failures with exponential backoff while preserving strict JSON behavior and avoiding replay after prompt side effects. (#196) Thanks @osolmaz.
• Docs/PR triage: add conflict gates and standard check validation guidance for maintenance PRs. (#180, #187) Thanks @osolmaz.
• Dependencies: update ACP SDK, workflow actions, TypeScript-native tooling, and development dependencies. (#131, #133, #146, #154, #177)

Breaking

Fixes

• Sessions/load: fall back to a fresh ACP session when adapters reject session/load with JSON-RPC -32601 or -32602, so persistent session reconnects do not crash on partial load support. (#174) Thanks @Bortlesboat.
• Flows/runtime: finalize interrupted flow run bundles as failed instead of leaving them stuck at running when the process receives SIGHUP, SIGINT, or SIGTERM. (#188) Thanks @osolmaz.
• Windows/process spawning: enable shell mode for terminal spawn on Windows. (#173) Thanks @Bortlesboat.
• Client/startup: add connection timeout and max buffer size limits. (#168) Thanks @Yuan-ManX.
• Client/auth: cache derived auth env key lists per auth method to avoid repeated allocations during credential lookup. (#167) Thanks @Yuan-ManX.
• Output/thinking: preserve line breaks in text-mode [thinking] output instead of flattening multi-line thought chunks into one line. (#194) Thanks @osolmaz.
• Agents/cursor: recognize Cursor's Session "..." not found session/load error format so reconnects fall back to session/new instead of failing. (#195) Thanks @osolmaz.
• Agents/kiro: use kiro-cli-chat acp for the built-in Kiro adapter command to avoid orphan child processes. (#129) Thanks @vokako.

2026.3.18 (v0.3.1)

Changes

• Dependencies: update TypeScript-native and tsdown development tooling. (#106, #107, #118, #125, #126)

Breaking

Fixes

• Codex/session config: treat thought_level as a compatibility alias for codex-acp reasoning_effort so acpx codex set thought_level <value> works on current codex-acp releases. (#127) Thanks @vincentkoc.
• Session control/errors: surface actionable set-mode and set error messages when adapters reject unsupported session control params, and preserve wrapped adapter metadata in those failures. (#123) Thanks @manthan787.
• Sessions/load fallback: suppress recoverable session/load error payloads during first-run prompt recovery and keep the session record rotated to the fresh ACP session. (#122) Thanks @lynnzc.
• Permissions/stats: track client permission denials in permission stats. (#120) Thanks @lynnzc.
