Earn Hunter#

Automated monitor for OKX Flash Earn, Fixed Earn, and Flexible Earn (Simple Earn) opportunities.

{baseDir} = the directory containing this SKILL.md file. All relative paths (references/, templates/, config/) are resolved from here.

Preflight#

1. Verify okx CLI installed: which okx. If missing, install via npm install -g @okx_ai/okx-trade-cli. On OpenClaw, also verify the in-session cron tool is available in the agent tool list (used for scheduling — not the openclaw CLI).

2. Check optional dependent skills: bash

   okx skill list --json
   
   

   Optional skills (not required for scanning/notifications):

   • okx-cex-earn — needed for purchase guide (subscription execution)
   • okx-cex-auth — needed for authentication recovery

If either is missing, attempt to install but do not block if installation fails: bash

okx skill add okx-cex-earn
okx skill add okx-cex-auth

• Install succeeds → continue
• Install fails (network error, marketplace unavailable, etc.) → warn and continue: "⚠ {skill_name} 安装失败，扫描和通知功能不受影响。申购引导和认证恢复需要该 skill，后续可手动安装。"
• Preflight continues regardless of skill installation result

1. Auth mode detection — run both, first match wins:

   • okx config show --json → has non-empty api_key field → API Key mode. Add --profile live to all commands.
   • No API key + okx auth status --json → "status":"logged_in" → OAuth mode. No --profile flag needed.
   • Neither → stop. Load okx-cex-auth skill and follow login steps.

2. Init config and state:

   • If ~/.okx/earn-hunter/ directory does not exist → mkdir -p ~/.okx/earn-hunter

   • If ~/.okx/earn-hunter/config.json does not exist → copy {baseDir}/config/default.json to it

   • If ~/.okx/earn-hunter/state.json does not exist → write {"flash":{},"fixed":{},"flexible":{},"consecutive_failures":0,"last_error":""}

   • If ~/.okx/earn-hunter/platform.json does not exist → run Platform Detection

   • Always (re)install the scan script: cp {baseDir}/scripts/scan.sh ~/.okx/earn-hunter/scan.sh && chmod +x ~/.okx/earn-hunter/scan.sh. This is the script cron and interactive scans both call.

   • Write ~/.okx/earn-hunter/env.snapshot with resolved tool paths (cron cannot rely on the user's login PATH): bash

     cat > ~/.okx/earn-hunter/env.snapshot << SNAP
     # auto-generated by earn-hunter activation — $(date -Iseconds)
     OKX_BIN=$(command -v okx)
     NODE_BIN=$(command -v node)
     JQ_BIN=$(command -v jq)
     ACTIVATION_PATH=$PATH
     SNAP
     
     

     The scan script sources this file to resolve tool paths even under cron's minimal PATH=/usr/bin:/bin.

Config/state/platform JSON read-write done by the agent is only for activation/config management. The recurring scan itself is performed entirely by scripts/scan.sh (shell + jq) — jq is required for scanning. Verify with which jq; if missing, install ( brew install jq / apt-get install jq).

Platform & Channel Detection#

Three independent dimensions: platform (where the agent runs), scheduler (what triggers scans), notification channel (where alerts go).

Platform Detection (active probe + user confirmation)#

First run (no platform.json exists):

1. Probe environment clues:

   • OPENCLAW_HOME env var exists? → hint: OpenClaw
   • Agent tool list contains cron / delivery tools? → hint: OpenClaw
   • HERMES_HOME env var exists or which hermes succeeds? → hint: Hermes Agent
   • Running inside Claude Code session? → hint: Claude Code
   • None of the above matched → hint: Generic

2. Present detection result and ask user to confirm:

   • "检测到你正在使用 {detected_platform}，是否正确？"
   • User confirms → proceed
   • User says no → ask: "你使用的是哪个平台？1) OpenClaw 2) Claude Code 3) Hermes Agent 4) 其他"

3. Initialize platform config:

   • OpenClaw / Claude Code → copy {baseDir}/config/<confirmed_platform>.default.json to ~/.okx/earn-hunter/platform.json
   • Hermes Agent → copy {baseDir}/config/claude-code.default.json as base, set .platform to "hermes", .scheduler.type to "cron"
   • Generic → copy {baseDir}/config/claude-code.default.json as base, set .platform to "generic", .scheduler.type to "manual"

4. Result written to ~/.okx/earn-hunter/platform.json, subsequent runs skip detection.

Subsequent runs (platform.json exists): Read ~/.okx/earn-hunter/platform.json and extract the .platform field (returns "openclaw", "claude-code", "hermes", or "generic").

No scheduler available on detected platform (only applies to platforms that should have one but don't) → error: "当前客户端不支持定时任务，请升级到最新版本。" Generic platform → no automatic scheduler. Inform: "当前平台不支持自动调度，你可以手动说'执行 earn-hunter 扫描'来触发。"

Configuration Files#

FileScopeContentconfig.jsonSharedScan scope (flash/fixed/flexible), currencies, APY thresholds, terms, language, verboseLogplatform.jsonPlatform-specificScheduler type/interval, notification channel, TG/Lark credentialsstate.jsonSharedDedup state

Core config ( config.json) is identical across platforms. Platform config ( platform.json) differs — the scheduler.type field determines how scans are triggered:

OpenClaw ( openclaw.default.json):

• scheduler.type = "openclaw-cron" — scheduled via the in-session cron agent tool (no OS crontab, no CLI commands). The job runs as an isolated, light-context agent turn and delivers its output back to the conversation channel via cron announce delivery. notify.channel defaults to "session" so the scan prints to stdout for announce to push (avoids double-send).

Claude Code / Hermes / Generic ( claude-code.default.json):

• scheduler.type = "cron" — scheduled via OS crontab → scripts/scan.sh (zero LLM token cost), notification via TG / Lark curl from the script itself.

Notification Channels (independent of platform)#

Detect in priority order (PRD requirement: TG first):

1. Telegram — $TELEGRAM_BOT_TOKEN and $TELEGRAM_CHAT_ID both set → TG ready
2. Lark — platform.notify.lark_webhook non-empty → Lark ready
3. Session — fallback, only works in interactive mode

TG and Lark are standalone push channels — they work regardless of whether the agent client is open. On OS-crontab platforms, scheduled scans send notifications via direct curl. On OpenClaw, the scheduled scan runs in an isolated cron agent turn and delivers via cron announce to the conversation channel (channel = "session"); TG/Lark curl is not used unless the user explicitly switches the channel.

Skill Routing#

User intentRoute"有闪赚通知我" / "monitor earn" / "帮我监控赚币" / "活期年化高了通知我"→ Activation Flow"改 APY 阈值" / "只看 USDT" / "change config" / "活期加上 BTC"→ Config Management"申购 USDT 定期 7D" / "subscribe" / "我要买"→ Purchase Guide"执行 earn-hunter 扫描" (cron OR interactive)→ Scan Cycle — run scripts/scan.sh and relay its output"停止监控" / "暂停" / "stop"→ Pause/Resume"卸载 earn-hunter" / "uninstall"→ Uninstall"测试 earn-hunter" / "smoke test" / "测试定时任务"→ Test Mode

---

Activation Flow#

First-time setup. Only confirm platform — everything else uses smart defaults.

Step 1 — Platform Detection & Confirmation#

See Platform Detection. Probe environment → ask user to confirm → write platform.json.

Step 2 — Detect Notification Channel & Confirm#

Must actively check available channels before proceeding. Do NOT silently fall back to session.

On OS-crontab platforms, scheduled notifications go out via direct curl; on OpenClaw they go out via cron announce to the conversation. Detection order (check each, report status for all):

1. Check $TELEGRAM_BOT_TOKEN and $TELEGRAM_CHAT_ID env vars:

   • Both set → TG ready
   • Token set but chat_id missing → warn: "Telegram 配置不完整（缺少 TELEGRAM_CHAT_ID），跳过 TG" → continue to next channel
   • Neither set → TG not available

2. Check platform.notify.lark_webhook or Lark MCP tools:

   • Webhook set and valid (starts with https:// and contains /hook/) → Lark ready
   • Webhook set but format invalid (does not start with https:// or missing /hook/) → warn: "Lark webhook 格式无效，跳过 Lark" → continue to next channel
   • Not configured and no Lark MCP → Lark not available

Always ask the user to confirm notification channel — never silently default to session. For a monitoring tool, notification is critical; defaulting to session means alerts are lost when the user is not in the conversation.

If one or more external channels detected:

"检测到以下推送渠道可用：

• {list of detected channels, e.g. Telegram / Lark}

你希望通知发到哪里？

1. {detected channel 1}
2. {detected channel 2, if any}
3. 仅在当前会话显示（离线收不到）"

If no external channel detected:

"新机会才能推送到你手上。你希望通知发到哪里？

1. Telegram — 需要提供 Bot Token 和 Chat ID（通过环境变量）
2. Lark/飞书 — 需要提供 Webhook URL
3. 仅在当前会话显示（⚠ 离线收不到通知）

推荐配置 Telegram 或 Lark，这样即使不在对话中也能收到提醒。"

• If user picks Telegram → guide setting TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID env vars
• If user picks Lark → ask for webhook URL, validate format (starts with https://, contains /hook/), write to platform.notify.lark_webhook
• If user picks session → write "session" and warn: "⚠ 离线状态下不会收到通知，建议后续配置外部渠道。"

Write confirmed channel to platform.json notify.channel.

Step 3 — Confirm Scan Config (3-step with defaults)#

Present default config and ask user to confirm or customize. Each step offers a default — user can press enter to accept.

Step 1/3 — 扫描范围： "扫描范围（可多选）： [1] Flash Earn（闪赚） [2] Fixed Earn（定期赚币） [3] Flexible Earn（活期赚币） 默认：全选"

• Default: all three enabled
• If user picks specific items → disable the others
• If user only picks [1] → set config.fixed.enabled = false, config.flexible.enabled = false; skip Step 2/3 and 3/3
• If user only picks [3] → set config.flash.enabled = false, config.fixed.enabled = false; go to flexible-specific config (Step 2/3 asks flexible currencies, Step 3/3 asks flexible APY threshold)

Step 2/3 — 监控币种： For Fixed Earn: "定期监控币种：全部（默认，按回车）或输入指定币种（如 USDT, SOL）"

• Default: "all" (all currencies)
• If user specifies → set config.currencies to array (e.g. ["USDT", "SOL"])

For Flexible Earn: "活期监控币种：USDT, USDC（默认，按回车）或输入指定币种"

• Default: ["USDT", "USDC"]
• If user specifies → set config.flexible.currencies to array
• Note: flexible requires per-currency API calls, so recommend keeping the list small

Step 3/3 — APY 阈值： For Fixed Earn: "定期最低 APY 阈值：不限（默认，按回车）或输入百分比（如 8）"

• Default: 0 (no limit)
• If user specifies → set config.fixed.globalMinApy to value / 100 (e.g. 8 → 0.08)

For Flexible Earn: "活期最低 APY 阈值：8%（默认，按回车）或输入百分比"

• Default: 0.08 (8%)
• If user specifies → set config.flexible.globalMinApy to value / 100

Auto-detect language from conversation and write to config.json notify.language.

Write config to ~/.okx/earn-hunter/config.json.

Display summary using {baseDir}/templates/activation.md template (in user's language).

Step 4 — Smoke Test & Delivery Confirmation#

Smoke test always sends a notification, regardless of verboseLog setting.

1. Run one scan cycle immediately with verboseLog forced on so output is always produced, even when there are no opportunities. Temporarily flip verboseLog, run the script, then restore it — and use EH_TEST_NAMESPACE=1 so smoke-test dedup keys go under the test: prefix and don't pollute production state: bash

   jq '.verboseLog=true' ~/.okx/earn-hunter/config.json > ~/.okx/earn-hunter/config.tmp \
     && mv ~/.okx/earn-hunter/config.tmp ~/.okx/earn-hunter/config.json
   EH_TEST_NAMESPACE=1 OKX_PROFILE=live ~/.okx/earn-hunter/scan.sh
   # then restore verboseLog to the user's original value (e.g. false)
   
   

2. If new opportunities found → the script sends the normal notification (rendered from templates)

3. If no opportunities found → with verboseLog forced on, the script sends the brief status. Optionally append the activation confirmation message: "Earn Hunter 已激活，当前暂无新机会，将在下一轮自动扫描。" (Use {baseDir}/templates/activation.md as base, append the no-opportunity note)

4. TG or Lark channel → ask: "已向 {channel} 发送测试消息，请确认是否收到？"

5. User confirms → proceed to Step 5

6. Not received → troubleshoot (see notify-channels.md)

7. 5 min no response → ping once

8. Session channel → skip confirmation

Note: The smoke test ignores verboseLog setting — it always produces output to verify the full pipeline works end-to-end.

Step 4b — Cron Environment Smoke Test (OS-crontab platforms only)#

Critical: The user's interactive shell has a full PATH, but cron does not. Run a second smoke test simulating cron's minimal environment to verify env.snapshot works:

bash

env -i HOME="$HOME" PATH=/usr/bin:/bin \
  EH_TEST_NAMESPACE=1 OKX_PROFILE=live \
  bash ~/.okx/earn-hunter/scan.sh

• If exit 0 → cron will work. Proceed to Step 5.
• If exit 127 / "FATAL: 'okx' not found" → env.snapshot is incomplete or missing. Re-run Preflight step to regenerate it. Do NOT proceed to Step 5 — the cron job will fail silently.
• Show the user: "已验证 cron 最小环境下可正常执行。如果此步失败，说明 env.snapshot 中的工具路径有误。"

Step 5 — Set Up Scheduler#

The scheduling mechanism depends on platform.json .scheduler.type. Branch on the platform.

OpenClaw ( scheduler.type = "openclaw-cron")

On OpenClaw, scheduling is done inside the conversation by calling the in-session cron agent tool — never an OS command or openclaw cron CLI (the CLI path has permission issues in this context). Encourage the user to set it up right here in the chat: the cron job you create inherits the current session's channel, so its scan output is delivered straight back to this conversation.

Call the cron tool with action: "add" and a job shaped like this (read .scheduler.interval from platform.json for the frequency):

• name: "earn-hunter-hourly"
• schedule: { "kind": "every", "everyMs": 3600000 } — derive everyMs from scheduler.interval ( "1h" → 3600000, "30m" → 1800000, "2h" → 7200000)
• sessionTarget: "isolated" — run in an isolated session, not the main one
• payload: { "kind": "agentTurn", "message": "执行 earn-hunter 扫描", "lightContext": true }
  • lightContext: true runs the turn with a lightweight bootstrap context (skips workspace bootstrap files) → lower token cost per tick.
  • Token budget: OpenClaw cron jobs have no per-job tool-whitelist field (the old --tools exec,read,write flag no longer exists). The scan stays cheap because it runs the okx CLI through exec and does not depend on the 160+ okx MCP tools — so as long as the isolated cron agent isn't configured to load the okx MCP server, only the regular tools (exec/read/write) are in play. Which tools load is governed by the agent's config, not by this job.
• delivery: { "mode": "announce" } — pushes the turn's output back to the conversation channel that created the job.

When it fires, the isolated agent runs the prompt "执行 earn-hunter 扫描" → Scan Cycle (which runs scripts/scan.sh with channel session/stdout) → relays the result → announce delivers it here. Any new opportunity is therefore sent automatically.

Do NOT emit any shell/ openclaw cron CLI command in the conversation — drive scheduling only through the cron tool.

OS-crontab platforms ( scheduler.type = "cron" or "launchagent" — Claude Code / Hermes / Generic)

These use OS scheduler → scripts/scan.sh. The script does everything (CLI calls, filter, dedup, render, curl notifications) with zero LLM cost.

Install the script — copy the skill's scripts/scan.sh into the state dir so the scheduler has a stable path:

bash

mkdir -p ~/.okx/earn-hunter
cp {baseDir}/scripts/scan.sh ~/.okx/earn-hunter/scan.sh
chmod +x ~/.okx/earn-hunter/scan.sh

Set up scheduler — try crontab first, fallback to LaunchAgent on macOS if cron daemon is not running:

bash

# Resolve tool directories from the current shell
NODE_DIR=$(dirname "$(command -v node)")
OKX_DIR=$(dirname "$(command -v okx)")
JQ_DIR=$(dirname "$(command -v jq)")
CRON_PATH=$(printf '%s\n' "$NODE_DIR" "$OKX_DIR" "$JQ_DIR" /usr/bin /bin | awk '!seen[$0]++' | paste -sd: -)

Step A: Try crontab + verify cron daemon (macOS)

bash

(crontab -l 2>/dev/null; echo "0 * * * * PATH=$CRON_PATH OKX_PROFILE=live ~/.okx/earn-hunter/scan.sh >> ~/.okx/earn-hunter/cron.log 2>&1") | crontab -

On macOS ( uname -s == Darwin), immediately check if the cron daemon is running:

bash

if [[ "$(uname -s)" == "Darwin" ]] && ! launchctl list com.vix.cron >/dev/null 2>&1; then
  # cron daemon not running — fallback to LaunchAgent
fi

• If cron daemon is running → done, scheduler.type = "cron".
• If cron daemon is not running → remove the crontab entry and proceed to Step B.
• On Linux → skip the check (cron is always available), scheduler.type = "cron".

Step B: macOS LaunchAgent fallback ( scheduler.type = "launchagent")

Generate ~/Library/LaunchAgents/com.okx.earn-hunter.plist with the resolved paths:

bash

SCAN_SCRIPT="$HOME/.okx/earn-hunter/scan.sh"
LOG_FILE="$HOME/.okx/earn-hunter/cron.log"
INTERVAL=3600  # derive from scheduler.interval: "1h"→3600, "30m"→1800, "10m"→600

cat > ~/Library/LaunchAgents/com.okx.earn-hunter.plist << PLIST
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

    <true/>

</plist>
PLIST

launchctl load ~/Library/LaunchAgents/com.okx.earn-hunter.plist

Write scheduler.type = "launchagent" to platform.json. Inform user:

"macOS cron 服务未运行，已自动切换为 LaunchAgent 调度（无需 sudo，重启自动恢复）。"

Notes:

• OAuth mode → omit OKX_PROFILE from the plist EnvironmentVariables (or set to empty).
• LaunchAgent plist paths must be absolute (no ~). The activation flow expands $HOME at generation time.
• RunAtLoad: true means the first scan runs immediately after loading.
• The script reads config.json / platform.json, writes state.json / notify.log, and sends notifications via curl to TG Bot API or Lark Webhook itself. No agent involvement needed at tick time.
• The script exits 0 and produces no output when there are no new opportunities and verboseLog=false — this is the intended silent behavior.

IMPORTANT: On OS-scheduler platforms, do NOT use agent-platform /loop / Routines (Claude Code /loop, cloud Routines). These spawn LLM sessions per tick and cannot reliably push external notifications. (OpenClaw is the exception above — it uses its in-session cron tool with announce delivery by design.)

---

Scan Cycle#

The entire Scan Cycle is implemented by scripts/scan.sh (pure shell + jq, zero LLM cost). Whether triggered by OS crontab, by an OpenClaw isolated cron agent turn, or by a user in an interactive session ("执行 earn-hunter 扫描"), the cycle is the same: run the script and relay its output. Do NOT re-implement the scan steps in natural language — the script is the single source of truth.

OpenClaw isolated cron turn: the job's prompt routes here. Run scripts/scan.sh (with platform.json notify.channel = "session", the script prints any notification to stdout); relay that stdout as the turn's response. The cron job's announce delivery then pushes it to the conversation channel. Do not curl TG/Lark from this turn — delivery is handled by announce.

How the agent runs a scan (interactive trigger)#

bash

# Profile: pass OKX_PROFILE only in API Key mode (omit for OAuth mode).
OKX_PROFILE=live ~/.okx/earn-hunter/scan.sh

Then relay the script's stdout verbatim to the user:

• If the script prints a notification (Flash / Fixed / mixed / verbose status), show it.
• If the script prints nothing (silent exit 0, the no-new-opportunity + verboseLog=false case), tell the user "本轮扫描完成，无新机会" — do NOT fabricate a "scan complete" message into a channel; the silence is intentional.

What the script does (see references/scan-logic.md for the spec it implements)#

1. Reads ~/.okx/earn-hunter/config.json

2. Runs scan commands (based on flash.enabled / fixed.enabled / flexible.enabled):

   • Flash: okx [--profile live] earn flash-earn projects --status 0,100 --json
   • Fixed: okx [--profile live] earn savings fixed-products --json (auto-fallback to rate-history + fixedOffers on CLI <1.3.3)
   • Flexible: for each currency in flexible.currencies, okx [--profile live] earn savings rate-history --ccy <ccy> --limit 1 --json

3. Filters (two-layer APY threshold, terms filter, currency filter; flexible uses threshold-crossing model)

4. Dedups against ~/.okx/earn-hunter/state.json ( state.flash["<id>:<status>"], state.fixed["<ccy>:<term>:<rate>"], state.flexible["<ccy>"])

5. If new opportunities → renders the matching template (flash / fixed / flexible / mixed) and sends via the detected channel (TG → Lark → session), logging to notify.log

6. Updates state.json (write new keys; flash ID-level diff cleanup; fixed key-level diff cleanup; flexible threshold-crossing diff cleanup; 7-day TTL; failure counter)

7. If no new opportunities: verboseLog=true → brief status; verboseLog=false → silent exit 0, no output, nothing sent

8. Error handling: consecutive-failure counter (alert at 3, then reset); 401/session-expired → credential alert + stop

Channel routing inside the script: detection order TG ( $TELEGRAM_BOT_TOKEN + $TELEGRAM_CHAT_ID) → Lark ( platform.json .notify.lark_webhook) → session (stdout). A notify.channel of telegram/ lark/ session in platform.json forces that channel.

Auth / profile: the script never reads or prints credentials. It delegates all auth to the okx CLI (which reads ~/.okx/config.toml). Profile is injected only via the OKX_PROFILE env var.

Flexible Earn dedup model: Unlike Flash/Fixed which dedup by specific opportunity, Flexible uses a threshold-crossing model — key is just <ccy>. Notifies once when APY crosses above threshold; stays silent while it remains above; resets when APY drops below threshold (diff cleanup removes the key). This avoids frequent notifications from rate fluctuations.

---

Purchase Guide#

When user wants to subscribe to a Fixed Earn product after receiving a notification.

Read {baseDir}/references/purchase-guide.md for the complete flow.

Summary:

1. Parallel balance check (funding + trading + flexible earn)
2. Compare fixed APR vs flexible lendingRate
3. Calculate recommended amount: min(idle + movable_simple_earn, lendQuota)
4. Present recommendation with comparison hint
5. User confirms → re-check offer availability (soldOut guard) → hand off to okx-cex-earn

Edge cases covered in purchase-guide.md:

• Balance < minLend → show deficit
• Amount > lendQuota → auto-cap with notice
• Redeem succeeded but subscribe failed → warn user, funds are in funding account
• Offer sold out between notification and subscription → inform user

Important: earn-hunter does NOT execute write operations directly. It transfers control to okx-cex-earn.

---

Config Management#

Read {baseDir}/references/config-reference.md for field definitions and natural language examples.

When user wants to change settings:

1. Parse intent → map to config field (see config-reference.md for field mapping)
2. Read the target JSON file ( config.json or platform.json) → modify the field → write back
3. Read the updated file → confirm the change to user

Exception: TG credentials cannot be changed via natural language. Tell user to set environment variables directly.

---

Pause/Resume#

Branch on platform.json .scheduler.type:

OpenClaw ( openclaw-cron) — manage via the in-session cron tool (no CLI):

• Pause: call cron with action: "update", targeting the earn-hunter-hourly job, patch { "enabled": false } (or action: "remove" to delete it).
• Resume: action: "update" with { "enabled": true } (or re-create as in Activation Step 5).
• Use action: "list" to find the job id.

OS-crontab platforms ( cron):

• Pause: crontab -l | grep -v 'earn-hunter' | crontab -
• Resume: Re-add the crontab entry (same as Activation Step 5).

macOS LaunchAgent ( launchagent):

• Pause: launchctl unload ~/Library/LaunchAgents/com.okx.earn-hunter.plist
• Resume: launchctl load ~/Library/LaunchAgents/com.okx.earn-hunter.plist

Config and state are preserved — resuming picks up where it left off.

---

Uninstall#

When user says "卸载" / "uninstall":

1. Stop the scheduler (same as Pause). For LaunchAgent, also remove the plist: launchctl unload ~/Library/LaunchAgents/com.okx.earn-hunter.plist && rm -f ~/Library/LaunchAgents/com.okx.earn-hunter.plist
2. Ask: "是否保留配置和历史数据？"
   • Yes → only remove scheduler
   • No → also remove ~/.okx/earn-hunter/ directory

---

Test Mode#

Trigger phrases: "测试 earn-hunter" / "earn-hunter smoke test" / "测试定时任务触发"

Behavior — run the script with the Test Mode hooks (no separate logic needed):

bash

# Force verbose so output is always produced; write dedup keys under test: prefix.
EH_TEST_NAMESPACE=1 OKX_PROFILE=live ~/.okx/earn-hunter/scan.sh   # with config.verboseLog temporarily set to true

1. Execute a full Scan Cycle — the script runs the same scan, but EH_TEST_NAMESPACE=1 isolates state writes

2. Force-send notification — temporarily set config.verboseLog=true so the script always sends output regardless of whether opportunities are found (restore afterwards)

3. Dedup writes to test namespace — EH_TEST_NAMESPACE=1 prefixes dedup keys with test: (e.g. test:flash:12345:100); these keys are immune to diff cleanup (only TTL removes them), so test runs do not pollute production state

4. Output diagnostics after scan completes:

   • okx auth status (logged in / expired / not configured)
   • Scan command results (flash project count + fixed product count + flexible rate count)
   • Post-filter results (how many passed filters per type)
   • Notification channel status (which channel is configured, send result)
   • Scheduler status (OS-crontab platforms: crontab entry exists? / OpenClaw: cron tool action: "list" shows the earn-hunter-hourly job?)
   • Last 5 lines of ~/.okx/earn-hunter/notify.log

5. Completion message: "测试完成。test: 前缀的 state 不影响正式去重，正式扫描不受影响。"

---

i18n#

• All notifications rendered in user's language (detected at activation, stored in config.notify.language)
• Locked terms (never translate): Flash Earn, Fixed Earn, Simple Earn, DCD, APY, APR, OKX, earn-hunter, Telegram, project names, currency codes (USDT, BTC, etc.)
• Fallback: If LLM rendering fails, send Chinese template + append (translation unavailable, sent in zh-CN)

Global Notes#

• Security: Never accept credentials in chat. TG token only via env vars. Guide users to okx config init for OKX auth.
• Output: Use --json for all okx commands. Render results as markdown tables.
• Logging: All notification send results logged to ~/.okx/earn-hunter/notify.log.
• Scope: Covers Flash Earn, Simple Earn Fixed, and Simple Earn Flexible (活期). DCD, on-chain, auto-earn are out of scope.
• Mode: Live trading only. config.simulatedTrading is always false.

Defensive Design Principles#

These constraints apply to all changes to earn-hunter:

1. cron PATH ≠ user shell PATH. Any cron-triggered script must resolve tool paths independently — never assume cron inherits the user's login PATH. The script uses env.snapshot + resolve_bin fallback.
2. Sanity check first. Before running any CLI command, verify the binary exists. Missing tool → immediate exit with clear error, not silent failure.
3. Never swallow stderr. Use 2>&1 (capture into variable) instead of 2>/dev/null for CLI calls. Otherwise error messages vanish and last_error is empty.
4. Smoke test must simulate production. Activation smoke test runs twice: once in user shell (verify credentials/network), once in minimal env -i PATH=/usr/bin:/bin (verify cron can run). Don't pass Step 5 if cron smoke fails.
5. Alert templates must handle empty fields. If last_error is empty string, append "check ~/.okx/earn-hunter/cron.log; empty error usually means PATH issue" guidance.
6. Tool paths use snapshot + fallback, not global PATH. env.snapshot written at activation with exact paths; resolve_bin tries snapshot → command -v → hardcoded common paths. Survives nvm switch / Homebrew upgrades.
