Grounded Engineering v0.6.0: now a Claude Code mod with a shelf of reviewed skill repos

I just shipped v0.6.0 of Grounded Engineering. The headline: it's now a Claude Code mod. The mod /grounded opens a live pane inside Claude Code with two screens. Practices reads signals from the repo you have open (languages, CI, test setup, etc.) and shows you which practice cards fit this repo, instead of handing you a generic checklist. The adapt skill proposes a concrete change for your approval. Skill repos is a shelf of sixteen reviewed third-party skill repositories, right inside the pane. The explain skill tells you what installing one would actually add before you commit to it. This is the part I'm most excited about: discovering good skills is currently a mess of random GitHub searches, and this is a curated shelf where someone already did the reading. Where the practices and skill repos come from Nothing here is generic advice. Every practice card is distilled from a real implementation I read: pattern, underlying principle, rationale, confidence level, and a citation to the exact source lines it was observed in. For example, the "gate network egress from agent-run work" card points at the allow/deny/approval decision and execution-scoped proxy construction in openai/codex's network_approval.rs, lines 625-820. Skill repos go through a review before they hit the shelf: each is read at a pinned commit, its license checked against SPDX, and its install steps must be literal commands you can verify. Anything else goes in an install note, not the steps. New practices in this release Four new cards sourced from openai/codex: expressing edits in an explicit verifiable format, deciding permission separately from the action, confining agent-executed commands in an OS sandbox, and gating network egress from agent-run work. The ai-assisted pack now ships seventeen cards. This keeps growing. New cards get added as new sources are reviewed, the shelf gets new skill repos, and existing entries get updated or re-audited when their sources drift (a source-drift check flags cards automatically). The mod is the delivery vehicle; the content is the living part.
