Preserve Mastodon API Compat

Category: Engineering  ·  Sub-category: backend  ·  Last updated:
Use when a change affects an observable contract surface — Mastodon REST API (/api/v1/*), GraphQL schema, ActivityPub actor object shape, JSON-LD context, OpenAPI spec, or error response format. Walks the contract impact across every consumer class and produces a coordination plan. Contract breaks require named coordination before landing.

From the source SKILL.md

lesser's contract surfaces are consumed by parties you cannot directly coordinate with — mobile apps, browser clients, third-party tooling, remote ActivityPub servers, sibling equaltoai repos, and operator-maintained integrations. Silent contract changes strand consumers; coordinated changes preserve the ecosystem relationship. This skill is the walk that turns "the contract is changing" into "the coordination plan that makes it safe."

What this skill does

Preserve Mastodon API Compat is a community-contributed Claude Code skill in the backend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/preserve-mastodon-api-compat/ and loads when your prompt matches the skill's trigger.
