The hook skips its advisory on two env vars: CLAUDE_SESSION_ID and
CLAUDECODE. runHook() cleared CLAUDE_SESSION_ID but inherited CLAUDECODE
from process.env, so tests run inside a Claude Code session silently
no-oped and produced no stdout, causing JSON.parse to throw.

* fix(hooks): skip read-guard advisory on Claude Code runtime (#1984)
Claude Code natively enforces read-before-edit at the runtime level,
so the gsd-read-guard.js advisory is redundant — it wastes ~80 tokens
per Write/Edit call and clutters tool flow with system-reminder noise.
Add early exit when CLAUDE_SESSION_ID is set (standard Claude Code
session env var). Non-Claude runtimes (OpenCode, Gemini, etc.) that
lack native read-before-edit enforcement continue to receive the
advisory as before.
Closes#1984

* fix(hooks): sanitize runHook env to prevent test failures in Claude Code
The runHook() test helper now blanks CLAUDE_SESSION_ID so positive-path
tests pass even when the test suite runs inside a Claude Code session.
The new skip test passes the env var explicitly via envOverrides.

* fix(hooks): add read-before-edit guidance for non-Claude runtimes
When models that don't natively enforce read-before-edit hit the guard,
the error message now includes explicit instruction to Read first.
This prevents infinite retry loops that burn through usage.
Closes#1628

* fix(build): register gsd-read-guard.js in HOOKS_TO_COPY and harden tests
The hook was missing from scripts/build-hooks.js, so global installs
would never receive the hook file in hooks/dist/. Also adds tests for
build registration, install uninstall list, and non-string file_path.
