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:
- inspect
- plan
- execute
- validate
- 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:
- summarize completed work
- cite the saved files
- state the resume point
- continue from the last checkpoint
