canopy

Trace any Canopy skill with live phase banners and per-node tree tracing. Respects the current mode — in plan mode no changes are applied; in edit mode the skill executes normally.

Canopy framework execution engine. Interprets canopy-flavored skills (any SKILL.md with a `## Tree` section) at runtime — platform detection, section semantics (`## Agent`/`## Tree`/`## Rules`/`## Response:`), tree notation (`<<`, `>>`, `|`), control-flow primitives (`IF`/`ELSE_IF`/`ELSE`/`SWITCH`/`CASE`/`DEFAULT`/`FOR_EACH`/`BREAK`/`END`), interaction primitives (`ASK`/`SHOW_PLAN`), execution primitives (`EXPLORE`/`VERIFY_EXPECTED`), op lookup chain, category directory semantics, subagent contract. Install this to execute existing canopy skills. Install `canopy` (the authoring agent) too if you need to create/edit/manage them.

Authors, validates, improves, scaffolds, and refactors Canopy skills using a structured control-flow notation (IF, ELSE_IF, ELSE, SWITCH, CASE, DEFAULT, FOR_EACH, BREAK, END, ASK, SHOW_PLAN, VERIFY_EXPECTED). Use when creating, modifying, debugging, or reviewing skills under `.claude/skills/` or `.github/skills/`, when the user mentions canopy, ops, control-flow notation, or skill scaffolding, or asks to convert a regular skill into a Canopy skill (and vice versa). Supports both Claude Code and GitHub Copilot.
