Import blocked: SDK, docs, and MCP generators will refuse this spec

The validation engine found 1 blocking violation: Reference could not be resolved.. Import tools reject the specification outright until it is fixed, so nothing downstream can be generated regardless of the other pillar scores. While this gate is open, the Standards Compliance score is capped at 40 and every AI pillar weights standards at 60% (normally 30%). Fixing the blocker in Phase 1 lifts the caps; the score projection below shows what that unlocks.

Executive summary

Your specification currently fails import: blocking violations make SDK, docs, and MCP generators refuse it, and the scores below are capped until they are fixed. Shuttle API scores 45/100: Not ready · Grade F. The weakest pillar is Standards compliance at 35; the strongest is MCP readiness at 53. We recorded 2250 finding instances: 1 critical, 38 high, 591 medium, and 1620 low. Gaps for AI-assisted builds. Ready for autonomous agents. Every finding lives in the specification, and the roadmap in this report orders the fixes by impact; resolving them projects the score to 100/100.

Readiness by pillar
Not ready 45 / 100
FoundationThe spec itself
35/100
Standards Compliance
OpenAPI validity, structural correctness, specification conformance, and import linting: can machines trust your spec?
35Not ready
Build Time ReadinessAI writes the code
49/100
Documentation Readiness for AI
Descriptions that say when to use an operation, examples that pin down every shape: whether an AI can learn the truth of your API from what you publish
45Not ready
SDK Readiness for AI
Clean types, predictable naming, correct formats: whether production-grade client code can be generated from your spec, by SDK pipelines and AI coding assistants alike
52Not ready
Runtime ReadinessAgents make the calls
53/100
MCP Readiness
Whether your operations survive being turned into tools: distinct names, descriptions that carry what an agent must know, safe invocation semantics, auth, error recovery, and context budget

About this report. We evaluated the Shuttle API specification against thousands of deterministic rules we have refined over twelve years of building API tooling, supplemented by AI-based analysis. Every finding is reproducible from the spec itself, scored consistently, and paired with a concrete fix.
What's at stake

What these gaps cost you in production

4 failure modes across 3 groups, each driven by your audit scores. Several are active risks today.

Foundation The spec itself 35 / 100
Active risk · Standards compliance
Your spec breaks before code is even written
2 critical/high finding group(s) in this area. Score: 35/100.
22→29
code quality score out of 40: the lift consumers achieve when the underlying spec is clean and standards-compliant

Build Time Readiness AI writes the code 49 / 100
Active risk · Documentation readiness for AI
AI readers can't learn the truth of your API
2 critical/high finding group(s) in this area. Score: 45/100.
74%
of developers name missing or unclear documentation as the top reason they abandon an API. AI readers are stricter: what a human would ask about, an AI assumes.

Active risk · SDK readiness for AI
AI-built integrations ship with guessed assumptions
No critical or high findings; 6 medium finding group(s) remain. Score: 52/100.
0
fabricated API constructs when a coding assistant was grounded in an AI-ready spec. Ambiguity in the spec is what triggers hallucinated integration code

Active risk · MCP readiness
Autonomous agents can't safely operate your API
No critical or high findings; 6 medium finding group(s) remain. Score: 53/100.
65%
reduction in token consumption when agent tools are grounded in authoritative API context. Bloated or confusable tools consume up to 3.3× more.
