Concise AGENTS.md cuts subagent token waste
In a post on X, AI developer SKatalystAI warned against treating AGENTS.md as an expansive project notebook, explaining that steering files are persistently injected into every subagent prompt and never compacted away. Bloated instruction files cause subagents to waste context windows and token budgets summarizing rules rather than executing tasks, underscoring the necessity of keeping AGENTS.md strictly constrained to essential goals and negative constraints.
Context bloat from unchecked persistent instructions is an insidious token drain in multi-agent architectures. Because AGENTS.md is continuously injected into subagent calls without compaction, large files compound token overhead across multi-step runs. Overloading agents with encyclopedic context files degrades reasoning budgets, prompting subagents to spend time summarizing constraints rather than executing code. High-leverage agent configurations keep persistent files tightly scoped to core objectives and explicit "never-dos" rather than detailed background notes.
