OrchestKit on pi, Codex and Cursor

Measured 2026-09-08 on pi 0.85.0, Codex CLI 2026.09.02 and cursor-agent 2026.09.02. Pick an engine to see what an OrchestKit install actually loads there, then flip the pi tool toggle to watch the skills vanish.

Surface	Loads	How	Verdict

pi headless probe, four runs

Same skills dir, same prompt, same model (z-ai/glm-5.3-flash over OpenRouter). The only variable that mattered was whether a file-reading tool was enabled.

built-in tools enabled (drop this and you get the sweep guard --no-builtin-tools)

Lane model: route by class of work

sweep

mech

skills ▓▓▓▓▓▓▓▓░░ 78 listed

Unattended writes inside a sandbox. pi with --approve, Codex --profile mech, cursor-agent --force --sandbox enabled. Skills yes, hooks no.
