Spec-Kit 0.8.13 Released: Loop Condition Fix and Agent Governance Update

Spec-Kit, the specification toolkit for modern software projects, has released version 0.8.13. This patch brings critical bug fixes and an extension update that tightens governance for agentic workflows. The update addresses a long-standing issue with while/do-while loops reading stale iteration-0 outputs and improves catalog parsing by rejecting boolean priority values. Additionally, the Agent Governance extension jumps to v1.2.0, introducing support for agentic workflows.

What Changed

The most significant fix is in issue #2662: while and do-while loops previously read stale output from iteration zero during subsequent iterations. This bug could cause infinite loops or incorrect results. The fix ensures each iteration reads the latest step output.

Another critical fix targets catalog readers: they now reject boolean values for priority fields. Previously, a boolean could slip through, leading to unexpected behavior in extension and preset catalogs. This change enforces type safety.

Documentation also gets a polish. The directory hierarchy in README examples was wrong—now corrected. On the extension front, Agent Governance moves to v1.2.0. This update adds agentic workflows for composable, multi-step automation. The changelog notes the bump but no further details—users should check the extension’s own release notes for specifics.

Why It Matters

Loop bugs are nasty. They can lock up pipelines or produce silent errors. This fix is a must-have for anyone using iterative specifications. The catalog type enforcement prevents misconfigurations that might otherwise go unnoticed until runtime. And for organizations adopting agentic workflows, the updated governance extension keeps policies in lockstep with evolving automation patterns.

Version 0.8.13 is a maintenance release, but it packs real value. The focus on correctness and consistency signals that the Spec-Kit team is serious about reliability. If you’re building with Spec-Kit, upgrade now—especially if you rely on loops or catalog-based extensions.
