Codex

Codex is not a second-class citizen. The skills are the same files, the CLI is the same CLI, and the protocol is identical — planx talks to both through a directory of JSON, so neither is privileged.

Start

/planx add rate limiting to the upload endpoint

If Codex is in Plan Mode

Codex has no tool for leaving plan mode on its own, so the skill prints:

press shift+tab to leave plan mode, then say "go"

Do that and the loop starts. (Under Claude Code the equivalent step is automatic — one accepted ExitPlanMode stub.)

Review

Exactly as everywhere else, in a second terminal tab:

planx <plan-id>

Leave a comment, press s, and paste the line it prints back into Codex:

│ 15 │

│ -16 Extend the snapshot-regression guard in `poller.ts` to │

│ -17 also reject a cross-period backward jump. │

│ +16 Reject the write at the R2 path, where every snapshot │

│ +17 already passes through one function, rather than in the │

│ +18 poller that happens to have produced it. │

│ 19 │

│ -19 - Compare the incoming timestamp to the last accepted one. │

│ -20 - Reject anything more than one period behind. │

│ -21 - Count the rejection against the node that sent it. │

│ +20 - Read the period key already on the object. │

• ·f leaves a comment on the line under the cursor
• ·s prints the one command you paste into the chat
• ·a instead of s, when there is nothing left to say

Executing

planx does not launch Codex for you. Approving a plan prints one command to paste into whichever session you want to build it in — see Executing.
