grok_agent

Launch a Grok CLI interactive agent TUI in a persistent terminal, sharing project settings and MCP tools, to run delegated tasks locally or on a registered remote terminal.

Instructions

【旧互換alias。新規連携は agent_launch(harness=grok-cli)】Grok BuildのGrokモデル(既定 grok-4.6)の対話エージェント TUIを永続端末に起動する。通常CLIと同じHOME・cwd・project/user/local設定・MCP・plugin・skill・permission/trustを共有する。aitermは完了相関stateだけをlaunch単位で所有する。起動されたagentにはsub-agent自己認識、親session、delegation depth/lineage、delegation_allowed=trueを注入し、必要な追加委譲は許可する。別のcomputer(登録済みの端末)で起こす時は、この起動にterminal(端末の登録元が渡す値をそのまま)とcwd(その端末のproject folder)を付ける。ここで起こしてからcd・sshしない。秘密の値はどの引数・prompt・送信文にも書かず、env_varsに名前だけを書く。turn は pty_send で送る(自動で非ブロック dispatch になる)。dispatch した子は投げっぱなしでよい=親はここで待たない。Codex親とClaude Code親にはAitermが回答本文を自動配送する。parent_deliveryがある場合はwait起動も通常の回答回収も不要。親は作業を続けるかターンを終える。Cursor親にはparent_deliveryとwait_processが付く。作業を続ければ次のツール返りに回答が差し込まれ、ターンを終える前にwait_processを背景で起動するとidle中の完了でも起きられる。ポーリングとpty_read(agent_transcript:true)は不要。その他の親では、完了通知をreceiptの wait_process.executable と wait_process.args をそのまま親のターンを塞がない別プロセスAPIへ渡して受け、PowerShell 7のStart-Processだけは windows_start_process_argument_list を単一文字列として渡す。exit を完了通知として扱う(exit 0=done / 3=timeout(既定600秒・未完了) / 4=closed / 7=error(harnessの記録でturnがAPIエラー等で打ち切られた。結果は無い)。receiptのoutcomeが正で、done以外は未完了。ポーリング不要)。wait_command は人間向け互換表示でありprocess境界へ使わない。foreground実行で親のターンを塞がない。自動配送以外の結果回収は pty_read(agent_transcript:true)。model/reasoning_effortを引数で指定可。read-only sandboxとagent_configureに対応。

Input Schema

NameRequiredDescriptionDefault
cwdNo作業ディレクトリ(対象リポのルート等・任意)。terminalを付ける時は必須で、その端末上のproject folderの絶対パス
fastNoファスト(harnessの高速の応答。費用や利用量が増える)。省略とfalseは通常の速度で起こす(利用者の設定にfastが残っていても通常)。trueは通常で起こしてから、その席をfastへ切り替える。modelがfastに対応していない時(FAST_MODE_NOT_SUPPORTED)と、modelへfast版のIDを書いてfalseを渡した時(FAST_MODE_MODEL_CONFLICT)は起動を断る。アカウントの都合で使えない時・確かめられない時は、起動を断らずに通常の速度で起こし、返りの fast を false、fast_error に訳を入れる。modelへfast版のIDを直に書いて省略した時だけ、そのIDのまま起こす(返りの fast は true)。
modelNo起動モデル。省略時は grok-4.6。explicit modelを起動前にlive catalogへ照合し、不在ならfallbackせずエラー
promptNo起動時に渡す初手プロンプト(任意)。送信後は待たずに即返る
env_varsNo起動したagentへ現在のMCP processから継承する環境変数名。値はtool引数へ渡さない
terminalNoRun this seat on another computer (a registered terminal) over SSH. Value: exactly the terminal value your host system's terminal registry hands over, {ref, target:{host,user,port}, trustRevision, and credentialRevision or credential {handle, revision}}; copy it unchanged, never invent or edit it, never use a host name or ssh command instead. Omit it to launch on this computer. Give cwd in the same call: the absolute project folder on that terminal. Never launch locally and then cd or ssh. Never put tokens, passwords or other secrets in any argument, prompt or typed text; pass secret values only by name in env_vars. After launch, use session_id alone for pty_send, pty_observe, pty_read, pty_key, claude_turn, agent_stop and pty_close; Aiterm routes them to the terminal. Errors and next step: TERMINAL_INVALID = malformed value, missing/relative cwd, or combined with remote: pass the registry's value unchanged with cwd. TARGET_MISMATCH / BINDING_UNKNOWN = the value is not this terminal's binding: ask the terminal registry again. HOST_TRUST_STALE / CREDENTIAL_REVISION_STALE = the binding changed: get the current value from the terminal registry and launch again. HOST_KEY_MISMATCH / HOST_TRUST_MISSING = the terminal's host key is not the trusted one: the Owner must confirm the new host key; do not retry. CREDENTIAL_REQUIRED / CREDENTIAL_NOT_LOADED = this terminal's key comes from a credential handle that the registry must load first; never paste a key anywhere. AUTH_FAILED = the terminal refused the key. UNREACHABLE = the terminal is offline; try later. CONNECTION_REFUSED = the terminal refused the SSH connection (SSH may be off there); try later. REMOTE_AITERM_TOO_OLD = update Aiterm on the terminal. CWD_UNAVAILABLE = the folder does not exist there; do not pick another folder. SEAT_FORWARD_UNAVAILABLE = the seat's MCP route back to this computer is not ready (launch again later), or the seat MCP URLs are not http://127.0.0.1:<one port>/api/seat-mcp. TERMINAL_HARNESS_UNSUPPORTED = use harness claude-code.
write_scopeNo能力宣言。read-only、または書込みを許可するパスの説明文字列。対応harnessのread-onlyはCLI標準のread-only面で実効禁止する
session_nameNoセッション名(省略で自動採番)
trust_projectNo対象projectを信頼し、既知のworkspace・project hooks・MCP初期同意を起動中に進める
reasoning_effortNoGrok Build reasoning effort。利用可能値はCLI/modelのlive catalogに従う。省略時はCLI/model既定。
throughline_source_sessionNo同一端末のThroughline sessionから所有権を変えずに記憶を読み、promptのmissionより前へ注入する
throughline_supplement_fileNoThroughline 0.10.8以降へそのまま渡すproject束縛済み長期記憶・知識の補足JSON path

TDQS

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden and does so extensively: it explains shared HOME/cwd/config/MCP/plugin/skill/permission state, Aiterm's launch-scoped completion state, injected sub-agent identity and delegation fields, non-blocking dispatch, parent delivery behavior, exit-code meanings, and secret handling. It also lists remote-terminal error codes and next steps, leaving little behavioral ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose and alias status are front-loaded, which is good. However, the description is a single dense block that mixes launch semantics, remote-terminal troubleshooting, parent delivery, exit codes, and result retrieval, with some repetition around polling and pty_read. The content is mostly relevant, but the structure could be much tighter.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 12-parameter launch tool with no annotations, the description covers the full lifecycle: local and remote launch, secret handling, parent-specific completion delivery, exit codes, error recovery, and result retrieval. An output schema exists, so return-value shape need not be restated. Nothing critical for correct invocation appears missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and each parameter already has a detailed schema description, so the baseline is 3. The prose reinforces a few cross-parameter rules such as terminal requiring cwd and env_vars passing secret names only, but these are already documented in the schema. It adds little value beyond the structured parameter documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens by stating it is a legacy compatibility alias and names the replacement, agent_launch(harness=grok-cli). It then gives a specific verb and resource: launching the Grok Build Grok model interactive agent TUI in a persistent terminal. This clearly distinguishes it from sibling launch tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly tells new integrations to use agent_launch(harness=grok-cli), framing this tool as an old alias. It also gives detailed when-and-how guidance: use terminal plus cwd for another computer, never cd or ssh after launching, use pty_send for turns, and follow parent-specific wait behavior. Alternatives and exclusions are present.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
