Graphite

Graphite is a code review platform built on top of GitHub for stacking pull requests, AI code review, and merging at scale. The gt CLI creates and submits stacked PRs, Graphite Agent (Diamond) provides codebase-aware AI review and chat, and a merge queue batches and tests PRs in parallel. Graphite has no standalone public REST API - it integrates through a GitHub App that consumes GitHub webhooks, the gt CLI (authenticated with a Graphite token), the GT MCP server, and label / GitHub-mediated integrations (Slack, Linear, external merge queue).

Graphite publishes 4 API contracts indexed on the APIs.io network, including Authentication API, GitHub App API, Merge Queue API, and 1 more. Tagged areas include Code Review, Stacked PRs, Merge Queue, AI Code Review, and Developer Tools.

The Graphite catalog on APIs.io includes 1 Spectral governance ruleset.

Graphite’s developer surface includes authentication, documentation, getting-started guide, CLI, changelog, engineering blog, pricing, and 36 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/graphite-com/apis.yml: open an issue on github.com/api-evangelist/graphite-com to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Agent Skills (SKILL.md packages)	builds-on	46.0	-	1
IDE Extension Marketplaces (JetBrains, VS Code, Open VSX, Docker Verified Publishers, PyPI orgs)	builds-on	46.0	-	1

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 3

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
