Terminal agent with customizable tools and sessions 4.23 / 5 [Directory score](https://instain.ru/en/ai/pi-coding-agent/#editorial-rating) [Official website ](https://pi.dev/) Pi works with the project from the terminal. It can be customized to your own process through extensions, project instructions, and a selected model provider. ![Pi documentation with instructions to start the agent in the terminal.](https://instain.ru/assets/images/pi-coding-agent-screen-5a356f5254ee-1200.webp) Pi documentation with instructions to start the agent in the terminal. [Open the source ](https://pi.dev/docs/latest/quickstart) ## Connect only the necessary tools Pi is launched from the terminal and works with the model and tools in the context of the project. If the standard set is small, an extension can add a command, event handler or tool. This is useful when in several repositories there is one acceptance procedure and you want to give the agent access to its verification. Start small. Difficult expansion makes it difficult to understand why the agent performed a certain action. The help describes the project instructions and the context of extensions. Place permanent rules separately from the text of a single task. So it is easier to see if the ban on editing applies to this repository or only to the current branch. ## Diagnosis of a broken test The example project uses two test configurations. One scenario passes only when run locally. Ask Pi to show the working directory, command, and environment setting that affect the result. A patch can wait. Compare the output with a clean CI run and check for a variable available only in the current terminal. If you have added your own extension, check it separately on the test copy. For example, the log reader should be limited to the desired directory and not return the entire output if the task concerns a single test. ## The border of trust Installing a package for Pi can expand the set of process actions. Before connecting, review the source code and conditions for accessing the model. Decide in advance what commands and files are needed for the task. ## Suitable tasks - Analyze changes and run checks from the terminal - Add your own tool to the work session Features ## Strengths - Extensions can register tools and commands - The project openly documents the setting and life cycle of the session Things to consider ## Limitations - Installable extensions need to be checked as executable code - The model provider and agent access to the working files are configured separately ## Selection and conditions Free access Yes Trial period Not confirmed No sign-up required Not confirmed Russian interface Not confirmed Local installation Not confirmed API Not confirmed “Not confirmed” means there is not enough information. The feature may still be available; check the developer’s terms. Input formats Code, Text Result Code, Text ### Terms The project is open to MIT. The model API conditions are determined by the selected provider. The model provider and agent access to the working files are configured separately From task to first result ## Practical example Task Analyze changes and run checks from the terminal What to prepare Training project with two test configurations, CI output and local start command. ### Task brief or prompt Explain the discrepancy between the two launches. Specify a working folder, variable or configuration file that affects the result. Don't change anything yet. ### Expected result Diagnosis with a play command and indicating differences in the environment. ### How to check the result - Repeat the check from a clean working copy. - Check that extensions have not been given access to the extra files. An editorial teaching example of a task brief, not the result of hands-on testing of the service. Check that the required mode is available, that you have rights to the source material and that the intended use of the result is permitted.
