Problem

Long-running agents lose track of their original goal, current position in the task, and what has already been attempted — leading to redundant work, circular reasoning, or silent failure.

Solution

Maintain a structured position log: at each step, record (goal, completed_steps[], current_step, remaining_steps[], blockers[]). At each iteration start, read position log before taking any action.

Implementation steps

Initialize position log at task start: { goal, steps_planned, steps_completed: [], current_step: null, blockers: [] }
Before each action: read position log and confirm current_step is not already in steps_completed (deduplication guard)
After each action: append to steps_completed, advance current_step pointer
Every 5 steps: run drift check — re-read goal and confirm current trajectory leads toward it
On blocker: append to blockers[], generate resolution options, attempt resolution or escalate if unresolvable after 2 attempts

Examples

–Multi-hour autonomous research agents
–Code migration tasks spanning 20+ files
–Data processing pipelines with conditional branch execution

Anti-patterns

–Storing position log only in model context — context compression destroys it
–Skipping drift check to save tokens — costs far more when agent goes off-course
–Treating blockers as terminal errors rather than resolvable obstacles
