Start hereClaude Codestrong workflow match. Top three in 97% of priority variations.

Why it fits

Documented use case: Developers already paying for Claude Pro or Max.

Check before choosing

The local CLI is host-first: OS sandboxing is disabled by default, may fall back to unsandboxed execution when unavailable unless failIfUnavailable is enabled, and covers Bash subprocesses rather than every tool

Ranking stability

How often each harness stays in the top three across 512 priority variations. This is not task success.

How this ranking worksOrdering, stability, and deal-breakers

Why this orderTools that fit your priorities appear first.

StabilityHow often a tool stays near the top when your priorities change slightly.

Deal-breakersNeighboring product layers and tools without current evidence for one are left out instead of receiving a lower score.

We first require documented coding-harness membership, then remove tools without current documentation for a must-have. The remaining products are ordered using published reference weights: main priority 30, approval style 25, change size 25, and work mode 20. We then vary those priorities 512 ways. The percentage is a stability check, not a task success rate.

22 of 35 active catalog entries pass coding-harness membership and every must-have in this workflow.

Why 13 harnesses do not match

These products are not ranked because they are outside the default coding-harness layer or at least one required condition is not currently documented.
