Debug - collect evidence, then diagnose

The issue to debug: $ARGUMENTS

You are debugging the patched Claude Desktop. Cowork runs on the .deb's bundled native VM backend (the old claude-cowork-service daemon is deprecated). Gather the relevant local evidence below (skip what's clearly irrelevant to "$ARGUMENTS"), form a hypothesis, then ask the user for anything you can't collect yourself. Read /architecture for how the pieces fit and /linux for session/CU specifics if relevant.

0. Resolve the config/log dir FIRST (1p vs 3p) - or you read stale evidence

The runtime dir is conditional: a 3p/enterprise deployment relocates everything to ~/.config/Claude-3p/. Resolve it once and use $CFG everywhere below.

# 3p (inference-gateway / Bedrock / managed) -> Claude-3p ; otherwise -> Claude
if [ -f /etc/claude-desktop/managed-settings.json ]; then CFG=~/.config/Claude-3p; else CFG=~/.config/Claude; fi
# sanity-check against the running process (named profiles add a further -<profile> suffix):
pgrep -af claude | grep -o -- '--user-data-dir=[^ ]*' | head -1
echo "using CFG=$CFG"

If pgrep shows a --user-data-dir that differs from $CFG (e.g. a named profile), prefer that path.

1. Last local-agent-mode session transcript (the single source of truth for Cowork/Dispatch/agent runs)

audit.jsonl records exactly what the model saw and did. Find the newest one and read the user's last prompt + the assistant tool calls + any errors:

AUDIT=$(find "$CFG"/local-agent-mode-sessions -name audit.jsonl -printf '%T@ %p\n' 2>/dev/null | sort -n | tail -1 | cut -d' ' -f2)
echo "newest audit: $AUDIT"
python3 -c "
import json,sys
p='$AUDIT'
if not p: sys.exit('no audit.jsonl found')
rows=[json.loads(l) for l in open(p) if l.strip()]
# user's first/last prompt
users=[r for r in rows if r.get('type')=='user']
def text(m):
    c=(m or {}).get('content')
    if isinstance(c,str): return c
    if isinstance(c,list): return ' '.join(x.get('text','') for x in c if isinstance(x,dict))
    return str(c)
if users: print('FIRST USER PROMPT:', text(users[0].get('message'))[:500])
if len(users)>1: print('LAST USER PROMPT:', text(users[-1].get('message'))[:500])
# tool calls + errors
for i,r in enumerate(rows):
    t=r.get('type')
    if t=='assistant':
        for c in (r.get('message',{}).get('content') or []):
            if isinstance(c,dict) and c.get('type')=='tool_use': print(f'[{i}] tool_use: {c.get(\"name\")} {str(c.get(\"input\",{}))[:120]}')
    elif t=='user' and ('Error' in str(r) or 'Permission' in str(r) or 'denied' in str(r)):
        print(f'[{i}] error/result: {str(r)[:200]}')
    elif t=='result': print(f'[{i}] RESULT: {str(r.get(\"result\",r))[:200]}')
"

If "$ARGUMENTS" is about dispatch/cowork/skills not working, this transcript usually shows the failing tool call, a permission denial, or a wrong path.
