Highlight vs StackResolve
StackResolve scores higher on the AgentReady, 100/100 against 46/100. They differ on 21 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.
What each one is
Highlight. The runtime control layer for AI development, de-risking releases, and enabling systems that heal and optimize themselves.
StackResolve. StackResolve is an independent registry that scores how ready software is for AI agents, and an API that compresses web research into structured calls.
Where StackResolve is ahead
StackResolve passes mcp discoverable, and Highlight does not. That is discover, whether an agent can find the product at all without being told it exists.
It also holds understand: openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented and limits / constraints documented. Highlight misses those.
And on adopt, self-service signup, no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, official python sdk, cli available and mcp integration available. Highlight misses those.
Finally, on operate, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable and agent compatibility verified. Highlight misses those.
Score, pillar by pillar
The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.
Discover. StackResolve leads 100 to 87. Highlight misses mcp discoverable; StackResolve misses nothing.
Understand. StackResolve leads 100 to 38. Highlight misses openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; StackResolve misses nothing.
Adopt is whether an agent can get a key and make its first successful call without a human in the loop. StackResolve leads 100 to 25. Highlight misses self-service signup, no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, official python sdk, cli available, mcp integration available; StackResolve misses nothing.
Operate. StackResolve leads 100 to 35. Highlight misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; StackResolve misses nothing.
