Codex Code Task (Async)

Run OpenAI Codex CLI in background β€” zero OpenClaw tokens while it works. Results delivered to WhatsApp or Telegram automatically.

Important: Codex = General AI Agent

Codex is NOT just a coding tool. In codex exec mode it is a general-purpose AI agent with file access, shell execution, optional web search, and deep reasoning.

Use it for:

  • Research β€” web search, synthesis, competitive analysis, user experience reports
  • Coding β€” create tools, scripts, APIs, refactor codebases
  • Analysis β€” read and analyze files, data, logs, source code
  • Content β€” write docs, reports, summaries
  • Automations β€” complex multi-step workflows with filesystem access

    • Give it prompts the same way you'd talk to a smart human β€” natural language, focused on WHAT you need, not HOW to do it.

    NOT for:

  • Quick questions
  • Tasks needing real-time back-and-forth

    • Quick Start

    What "run tests" means for this skill (critical)

    When user asks things like:

  • "run all tests"
  • "run tests"
  • "check if everything is working"

    • it means run the full E2E operator validation flow for run-task.py routing + notifications.

    It does NOT mean plain pytest/unittest discovery by default.

    Required behavior:

    1. Run routing validation first (--validate-only). 2. Launch smoke/E2E scenario via nohup and file-based prompt. 3. Wait for completion through normal async flow, not same-turn blocking. 4. Report PASS/FAIL against E2E criteria: routing, heartbeat, mid-task update, completion delivery.

    Use the canonical protocol: references/testing-protocol.md and the section below Full E2E Test (reference).

    Async Boundary Rule (mandatory)

    run-task.py is asynchronous orchestration.

    After a successful nohup launch, the correct behavior is:

    1. Send a short launch acknowledgment (PID/log/session) 2. Stop this turn immediately 3. Continue only when wake/completion event arrives in the same session

    Do not keep waiting in the same turn for Codex completion. Do not poll and then summarize in the same turn unless user explicitly asked for active live monitoring.

    Anti-pattern:

  • ❌ Launch run-task.py and keep responding as if completion should appear in this turn

    • Correct pattern:

  • βœ… Launch run-task.py β†’ acknowledge launch β†’ stop β†’ wait for wake

    • Launch Confirmation Gate (mandatory)

    Never claim "launched" until you have positive launch proof.

    Required proof checklist:

    1. nohup command returned a PID 2. process is alive (ps -p ) 3. run log contains πŸ”§ Starting OpenAI Codex... or equivalent startup marker 4. routing was validated (--validate-only) for Telegram thread runs

    If launch fails with ❌ Invalid routing:

  • resolve via sessions_list
  • rerun with explicit routing/session arguments if needed
  • re-check proof checklist
  • only then send launch acknowledgment

    • Pre-launch planning note (mandatory)

    Before launching Codex, post a short plan in chat:

  • how you plan to solve the task
  • what result you expect from this run
  • any clarifying assumptions
  • whether you expect one iteration or staged follow-up

    • If staged: explicitly say this run is "phase 1" and what signal decides phase 2.

    Telegram Thread Safety (must-follow)

    For Telegram thread runs, run-task.py is designed to either route correctly or fail immediately.

    Mandatory step before launch

    Resolve the current runtime session key first, then launch with it.

  • Get current key via sessions_list or runtime context
  • If key is agent:main:main:: β†’ use it directly in --session
  • Never derive --session from chat_id / sender heuristics

    • Rules

  • Use only --session "agent:main:main::" for thread tasks
  • Never use agent:main:telegram:user: for thread tasks
  • If routing metadata is inconsistent, script exits with ❌ Invalid routing
  • Default mode is --telegram-routing-mode auto
  • Force strict thread-only behavior with --telegram-routing-mode thread-only
  • Force non-thread behavior with --telegram-routing-mode allow-non-thread or --allow-main-telegram

    • This is intentional: abort fast > silent misroute

    ⚠️ ALWAYS launch via nohup β€” exec timeout will kill the process otherwise.

    ⚠️ NEVER put the task text directly in the shell command β€” save the prompt to a file first, then use $(cat file).

    WhatsApp

    # Step 1: Save prompt to a temp file
write /tmp/codex-prompt.txt with your task text
    Step 2: Launch with $(cat ...)
    
nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/codex-prompt.txt)" \
  --project ~/projects/my-project \
  --session "agent:main:whatsapp:group:" \
  --timeout 900 \
  > /tmp/codex-run.log 2>&1 &

    Telegram (thread-safe default)

    nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/codex-prompt.txt)" \
  --project ~/projects/my-project \
  --session "agent:main:main::" \
  --timeout 900 \
  > /tmp/codex-run.log 2>&1 &

    > Do NOT use agent:main:telegram:user: for thread tests/runs.

    Telegram Threaded Mode (1:1 DM with threads)

    When OpenClaw is used in Telegram threaded mode, each thread has its own session key like agent:main:main:thread:369520 or agent:main:main:topic:369520.

    Fail-safe routing (NEW): run-task.py now enforces strict thread routing.

  • If --session contains :thread: or :topic:, the script refuses to start unless Telegram target + thread session UUID are resolved.
  • It auto-resolves missing values from sessions_list when possible.
  • If the session is inactive and not returned by API, it falls back to local session files: ~/.openclaw/agents/main/sessions/*-topic-.jsonl.
  • If provided --notify-session-id mismatches the session key, it exits with error.
  • Result: misrouted launches/heartbeats to main chat are blocked before Codex starts.

    • Use --notify-session-id to wake the exact thread session:

    nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/codex-prompt.txt)" \
  --project ~/projects/my-project \
  --session "agent:main:main::369520" \
  --timeout 900 \
  > /tmp/codex-run.log 2>&1 &

    All 5 notification types route to the DM thread when --session key contains :thread: or :topic: βœ…

  • --notify-session-id β€” optional override. Usually auto-resolved from session metadata/files.
  • --notify-thread-id β€” optional override. Usually auto-extracted from --session.
  • --reply-to-message-id β€” optional debug field; avoid for DM thread routing.
  • --validate-only β€” resolve routing and exit (no Codex run). Use this to verify thread launch args safely.
  • --notify-channel β€” optional channel hint (telegram/whatsapp); target is always auto-resolved from session metadata.
  • --timeout β€” max runtime in seconds (default: 7200 = 2 hours)
  • --completion-mode β€” optional legacy hint (single default, iterate if explicitly needed)
  • --max-iterations β€” optional budget hint when using iterate mode
  • --trace-live β€” emit live technical trace markers into the same chat/thread (debug mode)
  • Always redirect stdout/stderr to a log file

    • Why file-based prompts?

    Research/complex prompts contain single quotes, double quotes, markdown, backticks β€” any of these break shell argument parsing. Saving to a file and reading with $(cat ...) avoids all quoting issues.

    Channel Detection

    The detect_channel() function determines where to send notifications:

    1. Deterministic auto-resolve β€” target is resolved from session metadata/session key (no manual target flag) 2. WhatsApp auto-detect β€” if the session key contains @g.us (WhatsApp group JID), WhatsApp is used 3. Fail fast on unresolved Telegram target β€” script exits with ❌ Invalid routing instead of silent misroute

    def detect_channel(session_key):
    if NOTIFY_CHANNEL_OVERRIDE and NOTIFY_TARGET_OVERRIDE:
        return NOTIFY_CHANNEL_OVERRIDE, NOTIFY_TARGET_OVERRIDE
    jid = extract_group_jid(session_key)
    if jid:
        return "whatsapp", jid
    return None, None

    WhatsApp notification flow

    1. Heartbeat pings every 60s β†’ WhatsApp direct 2. Final result β†’ WhatsApp direct + sessions_send 3. Agent receives completion payload β†’ processes it β†’ sends summary

    Iterative continuation mode (wake behavior)

    --completion-mode is optional and acts as a hint:

  • single = one run β†’ continuation summary β†’ stop
  • iterate = continuation summary + exactly one next iteration when gaps remain

    • Wake payload frames continuation as the same ongoing OpenClaw conversation after Codex replies to the previous launch.

    In iterate mode:

  • react briefly to Codex result
  • evaluate goal completion
  • if gaps remain: explain next fix and launch exactly one follow-up iteration
  • if complete: report final outcome and stop

    • Deterministic wake guard (anti-duplicate)

  • Each run carries run_id and wake_id
  • run-task.py keeps per-project state in /tmp/codex-orchestrator-state-.json
  • Duplicate/stale wakes are skipped before delivery

    • No silent launch policy (always-on)

  • Silent launch is forbidden (not only in debug mode).
  • On wake, agent must first post a visible decision turn:
    • - [TRACE][AGENT][WAKE_RECEIVED] ... - [TRACE][AGENT][DECISION] continue|stop ...
  • Only after that visible decision may the next Codex iteration be launched.

    • Telegram notification flow (DM Threaded Mode β€” full pipeline)

    1. πŸš€ Launch notification β†’ thread βœ… (silent; HTML;
    for prompt; via send_telegram_direct; includes Resume: ) 2. ⏳ Heartbeat (every 60s) β†’ thread βœ… (silent; plain text; via send_telegram_direct) 3. πŸ“‘ Codex mid-task updates β†’ thread βœ… (on-disk Python script /tmp/codex-notify-{pid}.py; Codex calls file; prefix "πŸ“‘ 🟒 Codex: " auto-added) 4. βœ…/❌/⏰/πŸ’₯ Result notification β†’ thread βœ… (HTML;
    for result; via send_telegram_direct) 5. πŸ€– Agent continuation reply β†’ delivered to chat via openclaw agent --deliver βœ… (same session continuation is visible to user)

    send_telegram_direct() is the core mechanism for all thread-targeted notifications from external scripts. It calls api.telegram.org directly with message_thread_id β€” bypasses the OpenClaw message tool entirely (which cannot route to DM threads from outside a session context).

    Fallback β€” if agent wake fails (session locked/busy): already_sent=True is set after the direct send, so no duplicate is sent.

    Key detail: Telegram vs WhatsApp delivery

    WhatsApp: Raw result sent directly (human sees it immediately) + sessions_send wakes agent for analysis.

    Telegram: Result sent via send_telegram_direct β†’ then agent is woken via openclaw agent --session-id --deliver so the continuation turn is visible in chat by default. This is the intended β€œsame agent, same conversation” behavior after Codex completion.

    Why not sessions_send for Telegram? sessions_send is blocked in the HTTP /tools/invoke deny list by architectural design. The openclaw agent CLI bypasses this limitation.

    Telegram DM Threads vs Forum Groups

    Telegram has two distinct thread models. The key difference for run-task.py is how to route messages to the thread.

    The core problem with external scripts:

  • The OpenClaw message tool's threadId parameter is Discord-specific β€” ignored for Telegram
  • Target format "chatId:topic:threadId" is rejected by the message tool's target resolver
  • Session auto-routing works only inside active sessions β€” external scripts have no session context
  • Solution: send_telegram_direct() bypasses the message tool entirely; calls api.telegram.org directly with message_thread_id

    • DM Threaded Mode (bot-user private chat with threads):

  • All notifications use send_telegram_direct(chat_id, text, thread_id=..., parse_mode=...) βœ…
  • thread_id auto-extracted from session key *:thread: or *:topic: by extract_thread_id()
  • Launch + finish: parse_mode="HTML" with
    for prompt/result
  • Heartbeats + mid-task: parse_mode=None (plain text, avoid Markdown parse errors)
  • parse_mode="Markdown" trap: finish messages contain text (CommonMark bold); Telegram MarkdownV1 rejects this with HTTP 400 β€” messages silently don't arrive
  • replyTo trap: combining replyTo + message_thread_id can cause Telegram to reject the request or route incorrectly
  • Agent continuation reply: openclaw agent --session-id --deliver publishes the wake turn to chat so the user sees the same ongoing assistant conversation

    • Forum Groups (supergroup with Forum topics enabled):

  • Same send_telegram_direct() approach works; message_thread_id is standard Bot API for Forum topics
  • Auto-detected from session key pattern *:thread: or *:topic:

    • Codex mid-task updates:

  • Do NOT embed bot tokens or curl commands in the task prompt
  • run-task.py writes /tmp/codex-notify-{pid}.py to disk before launching Codex
  • Task prompt prepended with [Automation context: ... python3 /tmp/codex-notify-{pid}.py 'msg' ...]
  • Codex calls the file as a normal local script
  • Script automatically prepends "πŸ“‘ 🟒 Codex: " to all messages; cleaned up in finally block

    • Reliability Features

    Timeout (default 2 hours)

  • --timeout 7200 β†’ after 7200s: SIGTERM β†’ wait 10s β†’ SIGKILL
  • Timeout notification sent to channel with tool call count and last activity
  • Partial output saved to file

    • Crash safety

  • try/except wraps entire main β†’ crash notification always sent
  • Both channel notification and agent wake attempted on any failure

    • PID tracking

  • PID file written to skills/codex-cli-task/pids/
  • Stale PIDs cleaned on startup
  • Can check running tasks: ls skills/codex-cli-task/pids/

    • Silent mode (Telegram only)

    Telegram supports silent notifications (no sound).

    Current policy: all Codex notifications are silent in Telegram:

  • Heartbeat pings β†’ silent=True
  • Launch notifications β†’ silent=True
  • Mid-task updates (πŸ“‘ 🟒 Codex) β†’ silent=True
  • Final results β†’ silent=True
  • Wake-summary instruction requests silent=True

    • WhatsApp does NOT support silent mode β€” the flag is ignored for WhatsApp.

    Notification types

    Codex CLI Flags

  • exec "task" β€” non-interactive run
  • resume "task" β€” continue a previous Codex session
  • --dangerously-bypass-approvals-and-sandbox β€” no confirmation prompts
  • --json --output-last-message β€” real-time activity tracking + final output capture
  • --full-auto β€” optional safer automation mode

    • Why NOT exec/pty?

  • exec has 2 min default timeout β†’ kills long tasks
  • Even with pty:true, output has escape codes, hard to parse
  • nohup + detached runner: clean, detached, reliable

    • Git requirement

    Codex needs a git repo. run-task.py auto-inits if missing.

    Python 3.9 Compatibility

    run-task.py uses Optional[X] from typing (not X | None) for compatibility with Python 3.9. The union syntax (X | None) requires Python 3.10+.

    # Correct (3.9+)
from typing import Optional
def foo(x: Optional[str]) -> Optional[str]: ...
    Would break on 3.9
    
def foo(x: str | None) -> str | None: ...

    Full E2E Test (reference)

    Use this when you need to validate the entire pipeline in one run:

  • launch notification in source thread
  • heartbeat after >60s
  • Codex mid-task progress update
  • final result in source thread
  • agent wake attempt with summary step

    • Pass criteria

    1. Launch message appears in the same thread (with expandable prompt quote) 2. At least one wrapper heartbeat appears after ~60s 3. At least one mid-task update appears (via /tmp/codex-notify-.py) 4. Final result appears in the same thread (expandable result quote) 5. Agent wake continuation is delivered (openclaw agent --session-id ... --deliver) and appears visibly in chat

    Canonical full test prompt pattern

  • keep prompt compact for routine testing
  • force runtime >60s (sleep 70) to trigger wrapper heartbeat
  • explicitly instruct Codex to call the notify script at least twice
  • include a short structured report so output is easy to verify

    • Interactive test rule (time budget)

    For iterate-mode testing, do exactly one continuation step after phase 1.

  • Phase 1: intentionally incomplete output
  • Continuation #1: close the gap and finish
  • Stop there

    • Reason: validates the iterative path without turning a routine test into a long multi-hop run.

    Visibility rule (mandatory)

    Between βœ… OpenAI Codex completed and any next πŸš€ OpenAI Codex started, there must be a user-facing analysis message in the thread.

  • The agent must first post what was done, what gaps remain, and the decision to continue/stop
  • Only after that message may it launch the next iteration
  • No silent jump from completion directly to next start

    • Canonical launch (minimal mode)

    cat > /tmp/codex-full-test-prompt.txt << 'EOF'

    1) notify script now
    

    2) create test file
    

    3) sleep 70 + notify again
    

    4) run several shell commands
    

    5) return short structured report

    Verification artifacts

  • wrapper log: /tmp/codex-full-test.log
  • Codex output: /tmp/codex-YYYYMMDD-HHMMSS.txt
  • session registry entry in ~/.openclaw/codex_sessions.json

    • Long-running task guidance

    If a Codex task is expected to run longer than ~1 minute, explicitly ask Codex to send intermediate progress updates during execution.

    Recommended wording:

  • "Send a progress update when you start"
  • "Send another update after major milestone(s)"
  • "If task exceeds 60 seconds, send at least one heartbeat-style update"

    • For Telegram thread-safe runs, updates should use the injected automation script (/tmp/codex-notify-.py).

    Canonical launch (minimal mode)

    cat > /tmp/codex-full-test-prompt.txt << 'EOF'

    Telegram Threaded Mode: Mid-task updates from Codex

    run-task.py automatically creates an on-disk notification script before launching Codex, so Codex can send progress updates without seeing bot tokens in the prompt.

    cat > /tmp/codex-prompt.txt << 'EOF'
STEP 1: Write analysis to /tmp/report.txt.
    After step 1, send a progress notification using the script from the
automation context above.
    STEP 2: Write summary to /tmp/summary.txt.
EOF
    nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/codex-prompt.txt)" \
  --project ~/projects/my-project \
  --session "agent:main:main::" \
  --timeout 1800 \
  > /tmp/codex-run.log 2>&1 &

    > Never embed bot tokens or raw curl commands in the task prompt.

    Cost

  • Codex runs outside the live OpenClaw conversation
  • zero OpenClaw tokens while Codex works
  • Codex billing depends on your Codex authentication mode

    • Session Resumption

    Codex sessions can be resumed to continue previous conversations. This is useful for:

  • follow-up tasks building on previous research
  • continuing after timeouts or interruptions
  • multi-step workflows where context matters

    • Resume ID β€” Critical Rule

    --resume takes the Codex thread_id, not run_id or wake_id.

    Correct source:

    πŸ“ Session registered:

    That is the value to pass as --resume .

    How to Resume

    When a task completes, the Codex thread_id is captured and saved to ~/.openclaw/codex_sessions.json.

    nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/codex-prompt.txt)" \
  --project ~/projects/my-project \
  --session "SESSION_KEY" \
  --resume  \
  > /tmp/codex-run.log 2>&1 &

    Session Labels

    Use --session-label to give sessions human-readable names for easier tracking.

    Listing Recent Sessions

    from session_registry import list_recent_sessions, find_session_by_label
    recent = list_recent_sessions(hours=72)
for session in recent:
    print(f"{session['thread_id']}: {session['label']} ({session['status']})")

    Or manually inspect:

    cat ~/.openclaw/codex_sessions.json

    When to Resume vs Start Fresh

    Resume when:

  • you need context from previous conversation
  • building on previous research/analysis
  • continuing interrupted work

    • Start fresh when:

  • unrelated task
  • you want a clean slate
  • previous context may cause confusion

    • Resume Failure Handling

    If a thread_id is invalid or expired:

  • error message sent to channel with suggestion to start fresh
  • process exits cleanly
  • check stderr in /tmp/codex-run.log

    • Common resume failures:

  • invalid thread_id
  • expired/non-resumable session
  • session from unrelated context or wrong project expectation

    • Example Workflow

    Step 1: Initial research

    write /tmp/research-prompt.txt with "Research the codebase architecture for project X"
    nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/research-prompt.txt)" \
  --project ~/projects/project-x \
  --session "agent:main:main::" \
  --session-label "Project X architecture research" \
  > /tmp/codex-run.log 2>&1 &

    Step 2: Find thread_id

    tail /tmp/codex-run.log
cat ~/.openclaw/codex_sessions.json | grep "Project X"

    Step 3: Follow-up implementation

    write /tmp/implement-prompt.txt with "Based on your research, implement the authentication module"
    nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/implement-prompt.txt)" \
  --project ~/projects/project-x \
  --session "SESSION_KEY" \
  --resume  \
  --session-label "Project X auth implementation" \
  > /tmp/codex-run2.log 2>&1 &

    Wake Troubleshooting

    When the agent wake / continue chain fails:

  • verify sessions_send is enabled
  • verify session visibility is all
  • verify Telegram thread routing with --validate-only
  • inspect /tmp/codex-run.log
  • inspect the session registry and output file path

    • Common failure patterns:

  • wrong thread session key
  • Telegram target/session UUID could not be resolved
  • stale or duplicate wake suppressed by dedupe guard
  • resume ID is wrong
  • progress helper was not called in long-running test scenarios

    • Current Stable Behavior

    This is the current intended behavior of the Codex adaptation:

  • wake continuity: the agent gets a continuation turn after Codex finishes
  • Telegram thread routing is strict by default
  • WhatsApp gets direct result delivery plus agent wake
  • session resumption uses Codex thread_id values captured from the JSON event stream

    • Current locally validated behavior in this repo:

  • Codex exec via --json
  • Codex resume
  • output capture via --output-last-message
  • OpenClaw-style async launch / heartbeat / completion flow in the runner logic

    Telegram Threaded Mode: Mid-task updates from Codex

    run-task.py automatically creates an on-disk notification script before launching Codex, so Codex can send progress updates without seeing bot tokens in the prompt.

    cat > /tmp/codex-prompt.txt << 'EOF'
STEP 1: Write analysis to /tmp/report.txt.
    After step 1, send a progress notification using the script from the
automation context above.
    STEP 2: Write summary to /tmp/summary.txt.
EOF
    nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/codex-prompt.txt)" \
  --project ~/projects/my-project \
  --session "agent:main:main::" \
  --timeout 1800 \
  > /tmp/codex-run.log 2>&1 &

    > Never embed bot tokens or raw curl commands in the task prompt.

    πŸ”’ Constraints

  • Use only --session "agent:main:main::" for thread tasks
  • Never use agent:main:telegram:user: for thread tasks
  • If routing metadata is inconsistent, script exits with ❌ Invalid routing
  • Default mode is --telegram-routing-mode auto
  • Force strict thread-only behavior with --telegram-routing-mode thread-only
  • Force non-thread behavior with --telegram-routing-mode allow-non-thread or --allow-main-telegram

    • This is intentional: abort fast > silent misroute

    ⚠️ ALWAYS launch via nohup β€” exec timeout will kill the process otherwise.

    ⚠️ NEVER put the task text directly in the shell command β€” save the prompt to a file first, then use $(cat file).

    WhatsApp

    # Step 1: Save prompt to a temp file
write /tmp/codex-prompt.txt with your task text
    Step 2: Launch with $(cat ...)
    
nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/codex-prompt.txt)" \
  --project ~/projects/my-project \
  --session "agent:main:whatsapp:group:" \

    Telegram Threaded Mode (1:1 DM with threads)

    When OpenClaw is used in Telegram threaded mode, each thread has its own session key like agent:main:main:thread:369520 or agent:main:main:topic:369520.

    Fail-safe routing (NEW): run-task.py now enforces strict thread routing.

  • If --session contains :thread: or :topic:, the script refuses to start unless Telegram target + thread session UUID are resolved.
  • It auto-resolves missing values from sessions_list when possible.
  • If the session is inactive and not returned by API, it falls back to local session files: ~/.openclaw/agents/main/sessions/*-topic-.jsonl.
  • If provided --notify-session-id mismatches the session key, it exits with error.
  • Result: misrouted launches/heartbeats to main chat are blocked before Codex starts.

    • Use --notify-session-id to wake the exact thread session:

    nohup python3 {baseDir}/run-task.py \
  --task "$(cat /tmp/codex-prompt.txt)" \
  --project ~/projects/my-project \
  --session "agent:main:main::369520" \
  --timeout 900 \
  > /tmp/codex-run.log 2>&1 &

    All 5 notification types route to the DM thread when --session key contains :thread: or :topic: βœ…

  • --notify-session-id β€” optional override. Usually auto-resolved from session metadata/files.
  • --notify-thread-id β€” optional override. Usually auto-extracted from --session.
  • --reply-to-message-id β€” optional debug field; avoid for DM thread routing.
  • --validate-only β€” resolve routing and exit (no Codex run). Use this to verify thread launch args safely.
  • --notify-channel β€” optional channel hint (telegram/whatsapp); target is always auto-resolved from session metadata.
  • --timeout β€” max runtime in seconds (default: 7200 = 2 hours)
  • --completion-mode β€” optional legacy hint (single default, iterate if explicitly needed)
  • --max-iterations β€” optional budget hint when using iterate mode
  • --trace-live β€” emit live technical trace markers into the same chat/thread (debug mode)
  • Always redirect stdout/stderr to a log file

    • Why file-based prompts?

    Research/complex prompts contain single quotes, double quotes, markdown, backticks β€” any of these break shell argument parsing. Saving to a file and reading with $(cat ...) avoids all quoting issues.
