Overview
Use this skill when the task is too large, too fuzzy, or too entangled to execute safely as one block.
When to Use
- the work enters as one oversized request
- the first useful slice is still unclear
- dependencies are making the task feel bigger than it should be
- the team needs a clear stop condition before execution expands
When NOT to Use
- the task is already a small, obvious slice
- the real problem is feature definition rather than execution shape
- the work needs macro gate or policy review instead of chunking
Core Moves
- Name the smallest useful slice that can stand on its own.
- Separate what belongs in this slice from what must wait.
- Identify the minimum dependencies needed for the current slice.
- Declare the stop condition for this round.
- Name the next slice only if it is already justified.
Optional Modules
- Dependency thinning — reduce or defer cross-system coupling when the slice is too entangled.
- Checkpoint insertion — add a short pause point when the work is likely to sprawl mid-round.
- Handoff-ready slicing — make the current slice legible enough for another round or another operator to continue later.
Activation Triggers
- Use dependency thinning when the task keeps expanding because of other systems or teams.
- Use checkpoint insertion when the round is likely to grow past one clean execution pass.
- Use handoff-ready slicing when another round, session, or agent may need to resume the work.
Expected Output
- smallest useful slice
- explicit in-slice versus later boundary
- dependency notes for the current slice
- stop condition for the round
- optional next-slice marker
Verification
- The current slice can be explained without listing the entire larger initiative.
- The stop condition is explicit enough to prevent silent scope growth.
- Dependencies kept for the current slice are truly necessary.
- The next slice is not being smuggled into the current one.
Handoff Signals
- The current slice is blocked by another ownership boundary.
- The next slice would require a different skill or operating context.
- Macro review or gate posture is needed before continuing.

Anti-patterns
- Renaming a large task as a “slice” without reducing it.
- Keeping hidden future work inside the current chunk.
- Treating chunking as a substitute for product or architecture decisions.
