One of the four files here is an OrcaReplay
capture: cursor-grok-4.5-high-system-prompt-2026-09-03.md,
1,955 characters, taken 2026-09-03.
It is one of the two shortest captures in the archive — Aider, added later, is 800 characters
shorter — and in Cursor's case that is the finding. Cursor composes the prompt on
its own servers and sends it back in the response rather than the request, over HTTP/2 in a
protobuf-framed stream — reaching it needs --tls-intercept and a local orca build. Another 19 KB
of environment, rules, skills and tool namespaces travels in the user turn, and Cursor declares no
tool schemas on the wire at all: two meta-tools in prose, the rest named in an XML attribute.
ORCA_BIN=packages/cli/dist/cli.js node capture/capture.mjs cursorDetails in docs/CAPTURES.md; the interception write-up is in CURSOR-HTTP2.md.
The cursor-agent-* and cursor-2.0-* files are inherited from CL4R1T4S
