skillxp
Python wrapper around skillxp, a Go CLI that observes how agent harnesses (Antigravity CLI, Claude Code, Codex CLI) load and activate Agent Skills: it installs a skill in a fresh fixture, invokes the harness headlessly, and reports what actually reached the model, with transcript evidence.
The wheel bundles the real Go binary for your platform.
CLI
pip install skillxp
skillxp harnesses
skillxp observe -harness claude-code -install ./my-skill \
-prompt "Activate the my-skill skill and follow its instructions." \
-activation -trace "PHRASE-IN-BODY-1234" -out out/
Identical to the Go CLI — see the project README for the full surface and the observation bundle layout.
API
The CLI writes its results to disk (observation.json, session.json,
archived transcripts) rather than printing a JSON envelope, so this
package carries no invocation API. Run the CLI via subprocess and read
the bundle; binary_path() exposes the bundled binary:
import subprocess
import skillxp
subprocess.run([skillxp.binary_path(), "observe", "-harness", "claude-code", ...])
Set SKILLXP_BINARY to override which binary the wrapper invokes.
