When an AI can enter your project or folder, the question is no longer only whether it gives a good answer. It can edit before it understands the rules, draw a conclusion from unchecked material, or say a job is finished halfway through.
These instructions give that kind of agent a clear way to work. The agent needs to understand the project and task before doing what needs doing. A small fix should not become a ceremony. But data, secrets, publication, and changes that affect each other need clear scope and impact before work begins, and a result you can check afterwards. Your tool’s permissions—and any real decision to publish or make an irreversible change—remain yours.

This instruction does not provide built-in knowledge of research, code, law, or any industry. It governs how an agent uses the user’s request, project files, tools, permissions, and checkable sources.
You may already use Follow YAGNI principles, Keep it simple, Verify before acting, Plan before execution, or Human in the loop. Those principles are useful, but on their own they usually do not define conditions, stopping points, or exceptions. These instructions turn them into working rules:
| Familiar prompt direction | What the short phrase leaves open | How these instructions make it operational |
|---|---|---|
Follow YAGNI principles / Keep it simple |
What can be omitted, and what is still required for this delivery. | Within the user goal and explicit scope, match effort to consequence, uncertainty, and reversibility. Include only issues that block acceptance, were caused by the change, or make the delivery inconsistent. Make the smallest sufficient related change, without letting persistence, sync, or governance expand the task automatically. |
Verify before acting |
What to verify, and what to do when sources conflict. | Check source coverage for complex work. Separate source, date, fact, inference, and what remains unverified. |
Plan before execution |
Whether small work needs a long plan, and when a plan is reliable. | Run a level-focus gate for long work. Use a full-picture plan only when it is aligned and the work is dependent, consequential, hard to recover, or externally consequential. |
Human in the loop |
What safe work can proceed, and what must stop for approval. | Proceed with authorized, low-risk, reversible, no-side-effect work. Require separate explicit authorization for publishing, deletion, access changes, spending, and other external actions. |
Manage context |
How to avoid long rules, search output, and stale context interfering with each other. | Map the scope with search, indexes, and sampling, then read direct material. Preserve handoff state separately for long-running work. |
These directions align with public guidance from OpenAI, Anthropic, and Google: use direct, structured rules; remove repetition; and keep the high-signal material needed to complete the work. This is not an endorsement of these instructions by any of them. The instruction integrates public principles with failure modes observed in practical agent work into one usable rule set. References: OpenAI model guidance, Anthropic context engineering, and Google prompt design strategies.
The reason for v1.0.1 is to add source coverage inside the level-focus gate: keep safety, authorization, sources of truth, acceptance, and high-risk counter-review while reducing cases where the agent sets a baseline before reading enough core sources.
This repo provides the complete meta instruction only. Tool-specific config files, imports, and installation locations should follow that tool’s documentation or your Agent Handoff Kit setup. Ordinary ChatGPT and Claude web chat are not supported here as reliable project agents.
Use the current official instructions or your Agent Handoff Kit setup for tool UI names and long-term instruction locations.
The instruction matches effort to impact. A clear small fix can be completed and read back directly. Work involving data, secrets, public release, or several dependent changes gets the extra checks and confirmation it needs.
You do not need to understand how the rules were assembled. Paste the full instruction into your tool, then begin with one small, real task.
