It gives developers and operators a shell-native way to inspect records, stream the firehose, work with PLC identity data, migrate accounts, administer PDS instances, and call XRPC endpoints. ### Project history The AT Protocol project emerged from Bluesky's protocol work: Bluesky described its spring 2022 ADX work as the first iteration, then announced the Authenticated Transfer Protocol on October 18, 2022. The protocol centers on portable identities, signed repositories, federation, Lexicon schemas, and HTTP/WebSocket synchronization. goat was forked from the Bluesky indigo codebase in August 2025 and had its first tagged release, v0.1.0, on August 12, 2025. Subsequent releases added and reorganized account, PDS admin, lexicon, dependency, and XRPC capabilities while tracking the evolving indigo SDK. ### Adoption history goat serves the AT Protocol developer and operations community rather than end users of the Bluesky app. The surrounding ecosystem had already encouraged third-party work: by October 2023, Bluesky documentation described developers building bots, clients, feed generators, and future applications on atproto. The Homebrew formula packages goat as a direct CLI install path for users who want an atproto toolbox without building from source. Its README also documents prebuilt binaries, Debian/Ubuntu packages, and go install. ### How it is used goat is used to resolve identities, list and fetch at:// records, export repositories and blobs, inspect PLC history, tail PLC operations, subscribe to relay firehose events, post through Bluesky APIs, manage lexicons, and make XRPC query or procedure calls. Some commands are public; account-modifying commands require login with an app password. ### Why package nerds care goat is interesting to package maintainers because it turns a fast-moving protocol stack into a reproducible local executable. For developers exploring atproto, it is the low-friction bridge between shell workflows, jq pipelines, Go-based SDK code, and network services such as PDSes, relays, PLC, Lexicon, and XRPC. Its presence in package managers is also a sign of the AT Protocol ecosystem maturing beyond one hosted application: protocol developers need inspection, migration, and admin tools just as much as client libraries. ### Timeline - 2022: Bluesky announced ADX had become the Authenticated Transfer Protocol. - 2023: Bluesky documentation invited developers to build bots, clients, feeds, and other projects on atproto. - 2025: goat was forked from indigo and tagged v0.1.0. - 2025: goat v0.2.0 added more lexicon management commands and required Go 1.25. - 2026: goat v0.2.3 added the first version of the xrpc subcommand. ### Related projects - goat is closely related to the AT Protocol, Bluesky, indigo, Personal Data Servers, relays, PLC identity infrastructure, Lexicon schemas, and the XRPC HTTP API model. ### Sources - - - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
