Add descriptions/2.16 spec (WIP)

[geetikabagga]

Why?

Publish version 2.16 of the public REST API OpenAPI specification so SDKs and reference docs generate against the new numbered version.

How?

Seeds descriptions/2.16 as a copy of the 2.15 spec, with info.version bumped to 2.16 — so it advertises nothing not yet served. Follow-up commits graduate the endpoints and fields newly promoted to 2.16.

Draft / WIP. Remaining: add the newly-promoted endpoints and fields, reflect breaking changes, keep Preview-only changes out of 2.16, and confirm the spec lints/bundles clean.

❌ PR Review Summary: NEEDS HUMAN REVIEW

	Summary
✅	🎯 Problem — The PR title and description clearly convey the motivation (publishing a new API version for SDK/docs generation) and approach, though they are slightly verbose with implementation details.
❌	📝 Alignment — The description claims 2.16 is merely a copy of 2.15 with info.version bumped, but the actual file is ~45% larger (35,407 vs 24,471 lines), already containing entirely new endpoints (e.g., /macros, /macros/{id}) with 11,113 lines of content not present in 2.15.
ℹ️	🧠 Correctness — Disabled for this repository.
❌	🦺 Safety — Any change under descriptions/2.*/ — including adding a new versioned spec — constitutes a change to the released public contract and always requires human review.
✅	🚦 Auto-approval — Within size limit (0/150 LOC).

Per-criterion details

Problem

Clear why (publish new API version for SDK/docs generation) and how (copy previous spec, bump version). The WIP nature and remaining tasks are documented. Slightly verbose with the implementation details, but the motivation is clear and upfront.

Alignment

Based on my analysis, the PR description claims that descriptions/2.16 is "a copy of the 2.15 spec, with info.version bumped to 2.16." However, the actual diff reveals:

1. 2.16 is 35,407 lines while 2.15 is only 24,471 lines — the new file is ~45% larger
2. 2.16 contains entirely new endpoints not present in 2.15, including Macros endpoints (/macros/{id}, /macros) with full operation definitions, examples, and error responses
3. 11,113 lines exist in 2.16 that are not in 2.15 (after normalizing the version string), compared to only 177 lines in 2.15 not in 2.16
4. There are substantial schema differences, new tags, and other additions beyond a simple version bump

The description explicitly states "it advertises nothing not yet served" and says "Follow-up commits graduate the endpoints and fields newly promoted to 2.16." But the spec already contains significant new content (like the Macros API) that doesn't exist in 2.15.

The PR description claims the 2.16 spec is seeded "as a copy of the 2.15 spec, with info.version bumped to 2.16" and "advertises nothing not yet served," with follow-up commits planned to add new endpoints. However, the actual file is dramatically different from 2.15:

• 2.16 has 35,407 lines vs 2.15's 24,471 lines (~45% larger)
• 2.16 already contains entirely new endpoints (e.g., /macros/{id}, /macros) with full specifications, examples, and error responses — these don't exist at all in 2.15
• After normalizing version strings, there are 11,113 lines in 2.16 not in 2.15, indicating massive additions beyond a version bump

The claim that it's "a copy of the 2.15 spec with info.version bumped" is factually incorrect. The file already contains significant new API surface area. The description also says "Follow-up commits graduate the endpoints and fields newly promoted to 2.16," but these are already present in this commit. This is a material misrepresentation of what the code change actually contains.

Safety

This PR adds a new file at descriptions/2.16/api.intercom.io.yaml, which falls under the descriptions/2.*/ path. The safety criteria explicitly state that any change under descriptions/2.*/ — regardless of whether it's a new version or an edit to an existing one — constitutes a change to the released, frozen public contract and always requires human review. Creating a new numbered release version is a significant action that establishes a new public API contract and affects SDK generation, reference docs, and downstream consumers.

<violated_criteria>
Released version specs — any change under descriptions/2.*/ (or any released 1.x/2.x-era version dir). These are the published, frozen public contract; a released-version edit always needs human review.
