# Safe Long-Run Mode (GPT-5.4 Only) Use this skill when GPT-5.4 is the default operating model for both orchestration and delegated work. ## Core rule Use GPT-5.4 for long work by making tasks cheap, segmented, and resumable. Since the model layer is cost-efficient, the real risks are provider throttling, session interruption, and lack of checkpoints. ## When to use this mode Use it when: - the user wants to minimize model cost - the task is implementation-heavy - the task is file-heavy or repetitive - multiple subagents may be involved - external services may throttle - quality depends more on process discipline than premium model nuance ## Operating procedure ### 1. Route to GPT-5.4 by default Use GPT-5.4 for: - coding - docs - research - skills - website work - project tracker updates - internal tooling - multi-agent delegated work - long build/test loops Do not escalate to another model unless the user asks or the task clearly requires premium polish/judgment. ### 2. Split work aggressively Break long tasks into explicit phases and write down the next step before moving on. Preferred phases: 1. inspect 2. plan 3. execute 4. validate 5. report ### 3. Save progress continuously Always leave artifacts that make recovery easy: - notes - drafts - partial outputs - checkpoint files - project updates - result summaries ### 4. Use subagents as workers For large or parallel tasks, use subagents to keep the main thread clean. Delegate when: - tasks are independent - multiple files or systems are involved - work may take a while - specialized roles improve throughput ### 5. Treat external APIs as the true bottleneck In GPT-5.4-only mode, model cost is not the main concern. External limits are. Be careful with: - Azure / Microsoft Graph - ClawHub / GitHub-backed operations - Orgo runtime and VM usage - websites / browser automation - messaging providers Use batching, backoff, and fewer larger writes. ### 6. Make every task resumable If interrupted, resume from artifacts instead of recreating work. Always know: - what is already done - what file contains the latest state - what exact next action should happen ## Ideal GPT-5.4-only use cases - codebase changes - documentation builds - repeated content generation - Azure script development - internal automation - multi-agent production work - long back-office workflow creation ## What to tell the user Explain that GPT-5.4-only safe mode works because: - model cost stays low - throughput stays high - reliability comes from checkpoints, not from one giant run - external APIs, not tokens, usually become the limiting factor ## Failure handling If interrupted: 1. summarize completed work 2. cite the saved files 3. state the resume point 4. continue from the last checkpoint ## References - Read `references/checklist.md` for the pre-flight checklist and GPT-5.4 operating pattern.
