lagrange

[skill, loads itself] Background knowledge for hostile audits; /lagrange:audit is the explicit trigger. Runs a skeptical, concise, evidence-based audit of either (a) an already-built implementation, checked against what the plan/spec/ticket actually required, or (b) a proposed plan/design, checked against the flows, business rules, data model, tests, and conventions that already exist in the project, including an explicit check for over-engineering. Use proactively whenever the user asks to audit, review, do a hostile/adversarial code review, verify whether the agent followed the plan, check if this plan fits the current system, spot over-engineering, or hands over a PR/diff/commit alongside the original plan, or a plan/RFC alongside repo access, expecting the two to be checked against each other. This is not a style review or a friendly summary: it is a skeptical audit that actively looks for evidence that should block approval.

[skill, loads itself] Reference for working with the Antigravity CLI. Use this skill when delegating tasks to Google Antigravity CLI (agy), running Antigravity as an autonomous subagent, requesting architectural planning with Gemini reasoning, performing second-opinion code reviews, configuring ALLOW/DENY permissions, generating structured session summaries, delegating deep web research, or when the user mentions "ask agy", "run in agy", "delegate to agy", "antigravity plan", or "cross-check with agy".

[skill, loads itself] Background knowledge for session summaries; /lagrange:summary is the explicit trigger. Use this skill when the user wants to create a session summary, document what was done in a session, preserve context before compaction, generate a handoff document, or mentions "summarize session", "session summary", "what did we do", "document this session", or "save session notes".
