21StarkCom/bifrost

Thirty skills and the TypeScript tools they call, served straight from this tree as a seven-plugin Claude Code marketplace. There is no build step: skill/ /SKILL.md is the artifact, and it ships when its PR merges.
Status: a public repo and a one-user personal playground. It is not production, and nothing here promises support to anyone but its author.
It exists so that one operator's way of working (how a ticket is written, a spec gated, a PR reviewed and merged, a session opened and handed over) lives in one place as skills any agent can run. Claude Code is the only install target. The skills are runtime-neutral, except /stark-memory, which tidies Claude Code's own auto-memory: Codex runs the same skill/ + tools/ trees (/agnes is $agnes on Codex), and Codex and Gemini are also dispatched as review agents.
It absorbed the stark-skills repo, which is archived.
## The legend of bifrost: The Burning Bridge
The Rainbow Road Between Source and Session
The name. Bifröst (Bilröst in Grímnismál) is the burning, three-coloured rainbow bridge that joins Midgard, the world of humans, to Asgard. Heimdall guards it from Himinbjörg, the gods ride over it daily to hold court at the Well of Urðr, and it is fated to shatter at Ragnarök when the sons of Muspell ride across (Gylfaginning). Its skills /gru, /minion and /agnes come from Despicable Me (2010): Gru the supervillain, his yellow Minions, and Agnes, the youngest of the girls he adopts.
The rainbow bridge is how the gods reach the world, and bifrost is how the operator's craft reaches every agent. One public source tree holds thirty-one skills and the tools they call, served straight from the tree as a seven-plugin Claude Code marketplace, with no build step. Cross the bridge and you meet a crew out of Despicable Me. /gru takes an epic and drives it with one Minion per ticket. /minion owns a single ticket through the whole spine. /agnes, named for the youngest girl Gru adopts and never one of his Minions, carries a ticket alone with no Gru at all. Their board is alfred, their horses are hermod's tabs, valkyrie launches them and their PRs pass through njord, both from idun, and frigg tells them where each repo lives. Beyond them wait a spec-to-code pipeline, a jury of Claude, Codex and Gemini, and a review poster that never posts the same review twice. When code must die, /stark-bury carries it down to nastrond. The quest stepped onto the bridge. Gru called a Minion, and Hermod saddled up.
Supporting cast. Every crossing passes a sentry: .github, the org's public front door and home of this saga, hosts the one reusable gitleaks workflow that more than forty fleet repos pin by SHA, scanning only the commits a change brings.
