SOUL ID pitches portable agent identity

The pitch is strong: agent workflows are fragmenting across runtimes, and a portable identity layer is the missing plumbing if these tools are ever going to feel continuous. The real test is less the schema and more whether multiple runtimes actually adopt the same trust and memory conventions.

• –The memory pointer-index approach is the right tradeoff for keeping context lightweight, but it only works if runtimes agree on retrieval semantics and retention behavior.
• –The ownership and signature layer matters more than the glossy registry story; without verifiable provenance, “persistent identity” turns into just another profile file.
• –Broad runtime support is the differentiator here, because cross-tool continuity is what developers actually feel when they move between editors and CLIs.
• –If the spec stays narrow and interoperable, it could become useful infrastructure for agent portability; if it grows into a platform, adoption gets much harder.
