Collaborative pseudocode authorship workflow. Engineer writes detailed pseudocode, or explicitly asks AI to draft proposed pseudocode; AI surfaces references, substantive edge cases, useful feature additions, and structural ripples; engineer explicitly approves; AI translates to body. Also handles drift-check on existing gantry docs and rebuild mode for existing code. Use when authoring a new function/feature, returning to extend an existing gantry doc, or auditing your mental model of existing code.

From the source SKILL.md

Gantry is an authorship discipline. The engineer stays in the design loop while AI writes code, so the resulting code stays comprehensible to its author (and onboarders) months later. The skill governs a single primitive — collaborative pseudocode design with a hard approval gate before any code is written — and applies it in three directions based on the state of the working tree.

What this skill does

Gantry is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/gantry/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when authoring a new function/feature, returning to extend an existing gantry doc, or auditing your mental model of existing code.

Who uses this skill
