Extends the .gitattributes eol=lf guard to assets/agents/** (33 embedded shell scripts share the CRLF failure mode the hooks rules fix) and scripts/*.sh. Adopts the probe-authored Scenario H: black-box checks of the installed log-events.sh (XDG default, 0600, UTC header, secret filter, symlink refusal) and notify.sh (control-byte-stripped fallback), plus non-executable .builtin-manifest.

# Black-box usage-pattern probe for the coyote hook system.
|
|
#
|
|
# Verifies, against a REAL built `coyote` binary in a clean/isolated
|
|
# COYOTE_CONFIG_DIR (dry_run:true, no network/LLM credentials required):
|
|
# A) exactly one turn.started + one turn.completed + one llm.request.completed
|
|
# fire per headless run, with correctly scoped env vars (no cross-event
|
|
# extras leakage).
|
|
# B) a failing/missing-script hook never changes coyote's stdout, stderr, or
|
|
# exit code.
|
|
# C) `coyote --install-builtins hooks` installs both bundled example scripts
|
|
# 0755 into <config_dir>/hooks via the real CLI; a non-interactive re-run
|
|
# keeps locally modified scripts while still installing missing ones.
|
|
# D) `coyote --agent <bundled-agent> --info` (an inspection flag) fires ZERO
|
|
# agent.* hook events.
|
|
# E) `coyote --install-builtins hooks` reconciles manifest-owned leftovers
|
|
# in roles/hooks and each bundled agent's hooks dir, sparing user files.
|
|
# F) top-level hooks-dir manifest reconcile: a stale shipped hook is removed
|
|
# on reinstall; a malformed manifest deletes NOTHING (fail-safe).
|
|
# G) a plain startup sweeps manifest-owned hooks of removed builtin agents
|
|
# while leaving user agent dirs and user files untouched.
|
|
# H) the INSTALLED bundled scripts behave as documented when run directly:
|
|
# log-events.sh defaults under ${XDG_STATE_HOME:-$HOME/.local/state}/coyote/
|
|
# (0600, UTC ISO-8601 header, secrets filtered, symlink at the default
|
|
# path refused) and notify.sh's no-notifier/no-tty fallback strips
|
|
# ANSI/OSC control bytes; the hooks-dir .builtin-manifest is never
|
|
# installed executable.
|
|
#
|
|
# Not covered here (see src/function/mod.rs tests for tool.* + payload-file
|
|
# coverage instead): a live tool.started firing requires a real LLM round
|
|
# trip that actually decides to call a tool; dry_run's echo_messages() path
|
|
# never invokes tools, so it cannot be exercised via this recipe.
|
|
#
|
|
# Usage: scripts/usage-probe-hooks.sh
|
|
# Requires: a `coyote` binary on PATH or at ./target/debug/coyote or
|
|
# ./target/release/coyote (build with `cargo build --bin coyote` first).
