Closes #80

Bug

lcx-doctor had two correctness issues (Problems 1 and 3 from #80):

1. Hardcoded /tmp — the skill instructed the agent to sync sources to /tmp/lazycodex-source and /tmp/openai-codex-source. On systems where /tmp is restricted or TMPDIR points elsewhere this silently breaks source sync.

2. Obsolete aggregate hook layout check — Step 3 directed the doctor to verify a hooks/hooks.json file under the installed plugin root. The current aggregate OMO plugin manifest (plugin.json) enumerates individual hook file paths directly in its hooks array; hooks/hooks.json is not used (this is explicitly asserted in test/aggregate-manifest.test.mjs). Checking for it produces a false negative against a correct installation.

Fix

• Replace every hardcoded /tmp path with ${TMPDIR:-/tmp} throughout lcx-doctor/SKILL.md. Introduce a SOURCE_ROOT="${TMPDIR:-/tmp}" variable in the bash sync snippet so it is set once.
• Replace the hooks/hooks.json payload check with the correct description: individual hook JSON files under hooks/ enumerated directly in plugin.json's hooks array.

Verification

Added two new assertions to the existing lcx-doctor test block in plugins/omo/test/lcx-bug-skills.test.mjs:

assert.match(skill, /$\{TMPDIR:-\/tmp\}/);
assert.doesNotMatch(skill, /\/tmp\/lazycodex-source/);
assert.doesNotMatch(skill, /\/tmp\/openai-codex-source/);
assert.doesNotMatch(skill, /hooks\/hooks\.json/);

RED before: node --test test/lcx-bug-skills.test.mjs → 2 pass / 1 fail
GREEN after: node --test test/lcx-bug-skills.test.mjs → 3 pass / 0 fail

Adjacent tests: node --test test/aggregate-manifest.test.mjs test/aggregate-skills.test.mjs test/aggregate-hooks.test.mjs → 18 pass / 0 fail

Summary by cubic

Fixes two correctness bugs in lcx-doctor: it now honors ${TMPDIR:-/tmp} for source sync and checks the current aggregate hook layout, preventing false negatives and broken runs on systems with restricted /tmp.

• Bug Fixes
  • Replaced hardcoded /tmp paths with ${TMPDIR:-/tmp}; introduced a SOURCE_ROOT variable in the sync snippet.
  • Updated payload check to expect individual hook JSON files under hooks/ as listed in plugin.json; removed the obsolete hooks/hooks.json check.
  • Extended tests to assert TMPDIR usage and the correct hook layout (no hooks/hooks.json).
