To limit skill leakage, developers should provide specific instructions in config files about the project build, test running, code conventions, and other important context. Task-specific instructions should be kept in separate markdown files with descriptive names, the researchers advise.
Additionally, to avoid conflicting instructions, builders should periodically review config files to remove instructions that are contradictory or outdated. Similarly, reducing init fossilization requires continuous updating of files, the researchers explained. This is particularly important in cases where an agent makes the same mistake twice in a row, a code review reveals a detail the agent should have already known, or when developers find themselves prompting corrections and clarifications already addressed in a previous session.
Finally, to minimize blind references, developers should tell agents when and why to read files, and include references with concise explanations of the document’s role, the information it contains, and scenarios where it should be used. For instance, text may reference an external dependency, include a link to its GitHub repository, and provide a brief explanation of its purpose. “Then the agent is able to understand the role of the dependency without needing to load or inspect the external repository directly,” the researchers explained.
