No idle notification. + Claude raises =idle_prompt= a minute after its turn ends; Codex has nothing like it. + =attention.synthesize_idle_waits= turns a Codex =Stop= or =Interrupt= record a minute old into a waiting request of kind =idle=, dated when the minute ran out, so =notify_kinds= and =notify_after_minutes= treat both harnesses alike and the request notifies once. +2. Questions only through =request_user_input=. + MCP elicitations raise no hook event, and whether =PreToolUse= covers =request_user_input= is documented ("local function tools") but not yet seen live. +3. A turn that fails raises no =Stop=. + A turn that ended in an API error (a 401, in the test) left the record at =working= until the next event; Claude has the same gap for an interrupted turn. + +**** Trust + +Codex runs a =-c= hook only after it has been reviewed and trusted. +Until then it is skipped without a message, though the TUI opens a "Hooks need review" screen at startup. +Trusting writes, into =$CODEX_HOME/config.toml= and by Codex itself, + +#+begin_example +[hooks.state."//config.toml:stop:0:0"] +trusted_hash = "sha256:..." +#+end_example + +one entry per event, keyed by event and position and hashing the hook's definition. +Hence the one design difference from Claude: the Codex hook command is identical for every launch, and the record key reaches it in =$SUCODER_ATTENTION_KEY= (put in front of the launch as =env SUCODER_ATTENTION_KEY==, outermost but for the environment file, so no extra cluster round trip). +The command checks the key at run time and writes nothing for an empty or unsafe one. +Measured: after one "trust all", a launch with a different key ran every hook without a new review. + +So review happens once per account and Codex home: =coder= on vantage, and the human's account on Savio (one home across nodes); and again whenever a SuCoder release changes =codex_overrides= (the command, a matcher, a timeout). +Press =2= ("Trust all and continue") on the first hooked launch. +A launch with no TUI (=codex_remote_control: server=) cannot show the review, so its hooks stay off until an interactive launch on that account has trusted them. +SuCoder does not pass =--dangerously-bypass-hook-trust=. + +Two consequences of =-c= that were checked: Codex runs embedded rather than on its shared background daemon when given =-c= overrides, and SuCoder's remote-control modes pass =-c= to the launch-owned app-server (=codex_remote.build_remote_command=), so each session's hooks see its own environment. +A launch whose command already sets a =hooks.= override is left alone. + +** Layer 2: one screen, sorted by need + +=sucoder attention= reads every record and lists the sessions that need the human first: + +#+begin_example +STATE AGE MIRROR TARGET HOST DETAIL +waiting 12m LSMS_Library carleton-htc n0043 Claude needs your permission to use Bash +waiting 3m SuCoder local vantage Claude is waiting for your input +working 40s K-Aggregators carleton-htc n0059 +ended 2h GradApps local vantage +#+end_example + +It reads the agent account's directory on this host, then the same directory once per cluster (targets that share a scheduler share =$HOME=;
