Agentic Loop
A closed-loop mechanism in AI programming that enables an AI agent to autonomously execute code, read the output, identify errors and make corrections, iterating repeatedly until tests pass, while humans recede into the roles of rule-setter and reviewer.
Core Facts
The core mechanism of Claude Code is the Agentic Loop, which is divided into four phases: receiving prompts, gathering context, executing actions, and verifying results.
The perception–reasoning–action loop forms the most fundamental Agentic Loop execution framework.
Timeline (last 90 days)
The core difference between the Agentic Loop and traditional conversational programming lies in the ownership of the feedback loop: in the former, the AI agent is responsible for running, reading errors and making modifications, while the human steps back into the role of rule-setter and result-reviewer.
The Agentic Loop can automatically fix problems with clear signals such as syntax errors, type mismatches and test failures, but it cannot judge whether the understanding of requirements is correct or whether the architectural choices are reasonable.
In the Agentic Loop, requiring the AI to write unit tests before delivering code is to provide the self-repair loop with executable pass/fail termination conditions.
In the Agentic Loop, the system prompt should set global constraints, such as which directories may be operated on, which errors must trigger a stop and a question, and which files are forbidden to modify.
ViCode proposed a three-step practical path for implementing the Agentic Loop: write the rules clearly in the System Prompt, require the AI to write unit tests before delivering code, and apply it immediately.
The precondition for the Agentic Loop to hold is that the AI can access a real execution environment, including the terminal, the file system and the test runner.
In the Agentic Loop, each iteration often derives a child context with a timeout from the Session context, used to constrain the maximum duration of a single tool call.
The repair agent is a feedback-loop-based AI execution mode (Agentic Loop): after the AI generates code, it triggers tests or builds, re-inputs error information into the model to generate patches, and loops until validation passes or the retry limit is reached.
The distribution of information and knowledge between agents at different levels must be handled with great care.
The agentic loop is very good at recovering from errors, so Omni made Blobby aware of how to recover from errors, gave it a budget to try, and refined high-quality error messages.
