MicTx/spec-harness (284 stars, +168 this week): (Task-package workflow for AI coding agents with verifiable scope, evidence, and Git gates.).

Below are 6 other Coding agents repos tracked by OSS Radar that share at least two GitHub topics about what they do with spec-harness (platform, language and framework tags don't count), ordered by how closely their topics overlap (rarer shared topics count more), then by stars gained in the last 7 days. Topic overlap means a similar problem space, not a drop-in replacement, so check each project's README.
