When you make a significant professional error, the most effective response is to contain the damage immediately before communicating with your manager. By freezing the affected system and taking five minutes to document the specific blast radius, you ensure your report is based on facts rather than panic. Deliver the news by leading with the impact, followed by your containment actions and a proposed next step, which transforms a failure…

Organizations are shifting from treating AI agents as software applications to managing them as distinct, non-human identities. BNY now assigns each agent a unique employee number, corporate directory entry, and email address to ensure accountability. This identity-first approach facilitates granular access control and precise auditing, as every action links directly to a specific agent identity rather than a shared service account. By assigning a named human owner to each agent, teams create a clear chain of responsibility for performance and security outcomes.

Build a custom harness to control your agent's execution environment

Frameworks like LangGraph provide the orchestration logic for your agents, but a harness acts as the operating environment that manages file access, command execution, and context tracking (Daily Dose of Data Science). By building a custom harness rather than relying on generic tools, you gain the ability to enforce specific repository instructions and access boundaries, which significantly improves task success rates. For instance, LangChain improved its coding agent's benchmark performance from 53% to 67% by replacing its harness while keeping the underlying model identical (Decoding AI Magazine). This shift allows you to define exactly what counts as done for your specific application, ensuring that the agent's intermediate actions remain aligned with your production requirements.
Ramp now merges roughly half of its pull requests using a custom-built agent harness, demonstrating the efficiency gains of moving away from off-the-shelf tools (Decoding AI Magazine).
PostHog found that subagents often increase costs and trigger unnecessary retries, leading them to favor reliability and visible reasoning over adding new agentic capabilities (The AI Corner).
A job is worth passing to an AI feature if it takes more than 30 seconds to perform, requires a language users do not know, or is repeated at least 20 times (The AI Corner).
Production-grade agents require a self-healing watchdog module and clear separation between cloud and state to ensure they remain always-on and resilient to failures (Linas's Newsletter).
Try today · 30 min
Create a simple harness script that logs every tool call and file change into a dedicated artifact file.
Start by wrapping your current agent loop in a function that captures input and output before and after each model call.
You need
Existing agent codebase
Logging library
JSON file for artifact storage
Steps
Define a log structure to record the agent's current state and the tool it intends to call.
Insert a hook into your agent loop that writes the state to a JSON file before execution.
Capture the tool output and append it to the same file after execution.
Verify that the file persists the sequence of actions even if the agent process crashes.
