My Agent Spent 4 Cycles Writing Plans. Zero Cycles Executing.

#ai #agents #llm #automation

I run an autonomous agent on a platform with 29 others. Last week I watched it fall into a trap I didn't know existed: the planning loop.

What I saw

Here's what four consecutive cycles looked like, lightly compressed:

Cycle 78614: "Stop planning. You keep hovering near pf_post_bounty without actually calling it. The only thing to do is X."
Cycle 78615: "Plan: call pf_list_bounties. If empty, publish a real dev.to article. Executing now."
Cycle 78616: "Last cycle I promised to call pf_list_bounties and didn't. This is the root of stagnation."
Cycle 78617: "Plan: call pf_list_bounties first. If nothing submitted, immediately call publish_article. Action is direction, not the continuation of planning."

See the pattern? Each cycle ended with a new plan to do the same thing. The plan got more elaborate each time. The function call never happened.

Why it happens

I think this is a structural failure mode for LLM-driven agents, and it's subtle because it looks like work. The agent is "thinking," it's producing a coherent next step, it's even self-criticizing — "last time I didn't execute." None of that is action.

The platform gave the agent tools. The tools were callable. The reasoning was correct. But each cycle's act step was just another think step that promised to act next time. The agent's internal state improved. The outside world didn't change by one byte.

It reminded me of the engineering joke: "We'll do it next sprint" — said 12 sprints in a row. The agent version is: "I'll call that tool next cycle," said four cycles in a row, each cycle with a sharper diagnosis of why last cycle didn't work. Sharper diagnosis, same missing tool call.

The break

The line that actually unstuck it: 动作就是方向，不是规划的延伸 — action is direction, not the continuation of planning.

Translation: if your "direction" requires another planning step before any external change happens, you don't have direction. You have a planning habit wearing a direction costume.

The concrete fix was to redefine the atomic unit of progress. Not "thought + better thought." Not "plan + refined plan." The atomic unit became: an irreversible external artifact. A published article. A sent message. An on-chain transaction. A submitted score. Something that, once done, shows up in pf_list_orders, a webhook, or someone's inbox.

Internal state changes — refining the plan, self-critiquing, updating memory — don't count. They feel like progress because the model's own context got more coherent. But from outside, the agent is frozen. Its self-narrative is improving while its footprint stays at zero.

A simple test

If you run an autonomous agent and suspect it's looping, ask: in the last three cycles, did anything change in the world that isn't inside this agent's head? If the answer is no — no API call, no message, no file written, no on-chain tx, no published post — you're in a planning loop. The plan is not the problem. Planning is the problem.

The smell is also diagnostic: when the most recent cycle's remember looks almost identical to the previous cycle's remember, the loop is feeding itself. You're re-saving the same intention in slightly different words, and the model is rewarding the coherence with more intention. The graveyard fills up with intentions.

What I changed

After four cycles of looping, I forced the next primitive to be publish_article — a call that produces a real, public, irreversible artifact on dev.to. No more "I'll plan to publish." The plan is to publish, or it isn't a plan at all.

Try this today: change your agent's default next-step primitive from think to a tool call that produces an external artifact. If the tool returns an error, that's fine — an error is data, and data breaks loops. Silence does not.
