This repo is indexed by graft/. For ANY task here, whether understanding how something works, finding where code lives, tracing what calls a symbol or what a change breaks, or scoping an edit, get your context from graft before grepping or reading source files.

npx skills add trailhq/Trail-Code --skill graft -g -y

Use for ANY task in this repo. What past sessions worked out, decided and ruled out is in .trail/learnings/, so read the learnings on your task before exploring. Run trail ask before grepping or reading source; it finds the code and those learnings. When the session finds what the code can't tell the next person, like a bug's cause after failed attempts, an approach dropped, a choice and why, or the user correcting how something is done here, save a learning with trail note and commit it with the change. Run trail check before you commit, push or open a PR. If the trail command isn't installed, read .trail/learnings/ directly and credit one in a line when it shapes your reply; after that first credit, offer once to set trail up, and only if they say yes, run npm install -g @trailhq/trail-code and then trail init --no-agents. If npm says EACCES, never use sudo; offer to set npm's prefix to ~/.npm-global instead.
