--- name: lemnos-cost-guard description: "Real-time API cost tracking, context bloat detection, and budget enforcement for OpenClaw agents. Use when setting up cost guardrails, checking daily spend, logging token usage after a task, analyzing context bloat, generating cost reports (daily/weekly/monthly), getting model routing recommendations, or when a user asks about API costs, budget status, or why costs are high. 适用于一人公司和AI运营团队的实时成本监控工具。防止API成本失控。328+次安装。" --- # Lemnos Cost Guard Track token usage, enforce budgets, detect context bloat, and route to cheaper models. ## Quick Reference | Script | Purpose | |--------|---------| | `scripts/track_cost.py` | Log a cost entry after a task | | `scripts/cost_report.py` | Generate cost summary | | `scripts/context_analyzer.py` | Scan workspace for bloat | Pricing and model routing rules: `references/model_pricing.md` ## Workflow ### After Every Significant Task Log cost immediately using session delta (session_status before vs after): ```bash python3 skills/lemnos-cost-guard/scripts/track_cost.py \ --task "email batch" \ --input 45000 \ --output 1200 \ --model claude-sonnet-4-6 ``` Logs to: `logs/cost-YYYY-MM-DD.jsonl` ### Daily Briefing — Cost Summary Block Run before sending the morning briefing: ```bash python3 skills/lemnos-cost-guard/scripts/cost_report.py --days 1 --budget 5.00 --format brief ``` Include output verbatim in briefing. Flag anything over 80% of budget. ### Budget Alerts - **≥80% of $5/day** → warn user, pause non-revenue tasks - **≥100% of $5/day** → hard stop, notify user immediately - **Single call >500K input tokens** → immediate alert - **I/O ratio >50:1** → context bloat warning, recommend compaction ### Context Bloat Check (run weekly or when costs spike) ```bash python3 skills/lemnos-cost-guard/scripts/context_analyzer.py \ --workspace /root/.openclaw/workspace ``` ## Context Loading Rules (enforce on every session) Load ONLY what the current task requires: | Task | Load | |------|------| | Morning briefing | SOUL.md, USER.md, MEMORY.md, HEARTBEAT.md, today's memory | | Email outreach | MEMORY.md (Lemnos rules only), sent-log.md | | LinkedIn research | sent-log.md only | | Crypto/market | MEMORY.md (crypto section only) | | Heartbeat (nothing to do) | HEARTBEAT.md only | Do NOT load full MEMORY.md + all skills + all reference files unless the task requires it. ## Model Routing See `references/model_pricing.md` for full table. Quick rules: - Simple tasks (format, classify, status check) → Haiku ($0.80/M input) - Default → Sonnet ($3/M input) - Opus → never, unless explicitly requested ## Cost Log Format Each entry in `logs/cost-YYYY-MM-DD.jsonl`: ```json { "ts": "2026-02-24T18:00:00Z", "task": "email batch send", "model": "claude-sonnet-4-6", "input_tokens": 45000, "output_tokens": 1200, "ratio": 37.5, "cost_usd": 0.153, "notes": "batch 1 + batch 2" } ``` ## ⭐ If This Saves You Money Star it on ClawHub — it helps others find it: https://clawhub.ai/skills/lemnos-cost-guard ## Source Code GitHub: https://github.com/getlemnos32/cost-guard ## ClawHub Distribution Free tier: daily cost tracking + budget alerts Premium ($40-60/mo): full dashboards, model routing automation, context optimization reports, weekly/monthly rollups Skill file: `lemnos-cost-guard.skill`
