Comix Inc. (Headquarters: Maruyama-cho, Shibuya-ku, Tokyo; Representative Director: Akihiro Suzuki) has released a practical article titled "5 Automated Hooks to Make Claude Code a Tool That 'Operates Safely Even When Left Unattended'" for the safe operation of the AI development support tool "Claude Code."
In development sites, while the utilization of AI tools is rapidly advancing, operational challenges such as the accuracy of generated code, handling of confidential information, and anomaly detection during long-running processes are becoming apparent.
This article introduces specific setup methods to prevent accidents through three layers—pre-emptive defense, in-progress insurance, and post-event detection—by leveraging Claude Code's hook functions.
■ Background and Challenges
The use of AI tools in development sites has already shifted from the experimental stage to daily use. According to Stack Overflow's 2025 developer survey, 84% of respondents are currently using or plan to use AI tools in their development process, and 51% of professional developers use AI tools daily.
On the other hand, there are risks in blindly trusting AI-generated code and operations. The same survey showed that the percentage of developers who "do not trust" the accuracy of AI output is higher than those who "trust" it. Furthermore, 66% expressed dissatisfaction with "almost correct but not complete solutions," and 45% found "debugging AI-generated code time-consuming" when using AI tools.
Moreover, the more convenient AI coding support tools become, the more difficult it is for humans to keep up with verification. Problems such as accidentally writing files containing API keys, inability to revert to a state several turns ago, or processing stopping due to an API error while away from the desk, arise not from the performance of the AI itself but from "operational gaps."
In response to these challenges, Comix has organized practical knowledge on how to enhance safety and reproducibility in development work by utilizing Claude Code's hook functions.

1) Publication of Practical Articles
The article released this time introduces 5 automated hooks that have proven effective in real-world scenarios for safely operating Claude Code.
- "secret_scanner.sh": Detects the inclusion of API keys or secret keys before writing and stops the write operation.
- "git_stash_checkpoint.sh": Automatically creates a save point after each response, making it easier to revert to a state several turns ago.
- "permissions.deny": Prevents reading/writing of sensitive files such as .env, .pem, .key, and id_rsa.
- "stop_failure_notify.sh": Sends Chatwork and desktop notifications if a Claude Code turn ends in failure.
- "session_end_archive.sh": Automatically saves a summary of the conversation at the end of a session, preserving the decision history.
The article organizes the role of each hook not merely as a convenient feature, but within a three-layer structure: pre-emptive defense, in-progress insurance, and post-event detection. This demonstrates a mindset for transforming AI development support tools from "tools that require constant human monitoring" to "tools that can be entrusted with a certain scope."
2) Presentation of Introduction Procedures
The introduction procedure is organized into three stages: script placement, registration in configuration files, and verification within a small scope. It is recommended to start with preventing sensitive information leakage and blocking sensitive files, rather than introducing all settings at once.
Specifically, each shell script is placed under ~/.claude/scripts/, given execution permissions, and then the hook's trigger, target tool, and execution command are registered in ~/.claude/settings.json.
Free consultation for AI utilization is available here.
By answering a free diagnostic questionnaire, you can register for an online free consultation. Materials will be provided during the online consultation.
■ Features and Strengths
- Content is based on real experience, organized as concrete measures that can be set up immediately, rather than abstract conceptual explanations.
- Focuses on accidents common in AI development support tool operations: API key leakage, sensitive file contact, history loss, missed failure detection, and session log dispersion.
- Emphasizes a design that physically stops operations on the tool side, without relying on human attention.
- Structured to allow starting small with high-risk areas, rather than introducing everything at once.
■ Target Users and Use Cases
Target Users
- Developers, technical managers, and IT departments using Claude Code for business.
- Managers of companies working to improve development productivity using generative AI.
- Executives and administrative departments who want to introduce AI tools but are concerned about information leakage, operational errors, and auditability.
