Claude Code prompts get safety-first templates

Claude Code prompts get safety-first templates

3 Key Points

  1. What happened

    The author prefixes every Claude Code request with a tag like "安全タスク/READ ONLY調査" or "安全実装タスク" so the AI knows upfront whether the job is read-only research or a change-making implementation.

  2. Why it matters

    A single generic prompt can read as permission to run implementation steps during a research-only task, or skip verification. Separating safety conditions, steps, required tests, and report format is meant to reduce such gaps.

WHO IT HITSThis lands on developers and team leads who delegate coding or investigation work to AI agents: it gives them a concrete structure for stating what the agent may not do and what counts as done, rather than trusting the model's judgment.

Context & Analysis

The template treats the boundary-setting as the human's job. Prohibited actions and steps are written separately, so the purpose of the request and the constraints on the work are not mixed together. The author notes that a request like "please fix this feature" alone leaves the range of permitted changes and the conditions to verify undecided — the intent may be clear, but what the AI is allowed to judge remains vague.

The completion definition follows the same logic. Making a change and finishing the job are not the same thing. By making required tests a template field and fixing the report format, the person reading the report can see not only what was changed but how far it was verified. The author stresses that the specific prohibitions differ from task to task, so a common template cannot replace individual judgment. The reason to use the template is to avoid leaving those premises vague each time work is requested.

FAQ
What is the difference between the two task prefixes?
「安全タスク/READ ONLY調査」 is for research, where the goal is to read the current state. 「安全実装タスク」 is for implementation, where the goal is to make necessary changes and then verify them.
What does the template ask for besides the request itself?
It also specifies safety conditions and prohibited actions, work steps, required tests, and the format of the final report.
Does using the template guarantee the work is safe?
No. The author says it does not guarantee all work is completed safely. The template is a frame for reducing oversights, not a replacement for human judgment.
