GOAL
Modify the ppi Docker wrapper script to trigger RPC mode via --mode rpc instead of only --port, and add configurable internal/host container port flags.
- +2mPrompt · +2mPropose only (no code changes): allow --mode rpc to trigger RPC mode, and add --ppi-container-port and --ppi-host-port flags, with host port defaulting to container port (default 3000).
- +4mPrompt · +4mYou can ignore backward compatibility; please implement.
- +6mFail · +6mMultiple edit attempts on ppi failed repeatedly with 'Could not find edits, oldText must match exactly' errors, even after re-reading file offsets and checking whitespace with cat -A.
- +6mAgent did · +6mDebugged the exact-match edit failures by reading file sections, using sed and cat -A to inspect whitespace, and finally used Python byte-search to find the exact text before applying smaller, targeted edits (e.g. changing 'text|json)' to 'text|json|rpc)').
- +11mIntervention · +11mTold the agent to implement the port/mode changes but explicitly not to remove the --port flag, leaving that for the human to do manually.Why: I wanted to remove --port myself since the agent kept struggling with matching that section of the file.
- +11mAgent did · +11mAdded use_ppi_container_port and use_ppi_host_port variables (default 3000), new --ppi-container-port/--ppi-host-port flag handlers, updated is_valid_mode and the docker run condition to trigger on --mode rpc, and wired the port variables into the -p mapping and PORT env var.
- +15mIntervention · +15mTold the agent 'I have removed the --port flag, do nothing' after manually editing the script.Why: I removed the leftover --port flag myself by hand since I'd told the agent to leave it alone.
- +15mPrompt · +15mUpdate the README to cover the cleaned up --port flag.
- +15mAgent did · +15mUpdated README.md to remove --port references, document --mode rpc as the RPC trigger, and describe the new --ppi-container-port and --ppi-host-port flags with updated examples.
- +18mOutcome · +18mSession ended with a request to commit all changes on the current branch with a meaningful, self-credited commit message and verify a clean working tree.
VERDICT
Next time I'd ask upfront for the exact diff format the tool needs, since a huge chunk of this session was wasted on the edit tool failing to match whitespace-exact oldText in the ppi script. The intervention that actually helped was telling it to leave the --port flag removal to me by hand — the agent kept tripping over that section, and doing it myself was faster and safer.
