Problem

p0 allow accepts unknown options and forwards them to P0 as part of the command. That meant --debug was never consumed by the CLI: it was sent to the backend as an allow argument, and no debug output was printed.

Status: N/A

Change

p0 allow now declares a --debug option, so the CLI consumes it instead of forwarding it. It also passes the flag to authenticate(). fetchCommand prints the argv it sends to /command and the raw response or error that comes back, to stderr, when debug is set. The output never includes the bearer token or the Authorization header, only the argv, the response data and the error.

--help is unaffected: it still reaches P0 and lists the requestable resources.

Because the output lives in fetchCommand, p0 request, p0 grant and non-admin p0 ls print the same debug lines when run with --debug. This is intended.

  • authentication / authorization
  • workflow
  • APIs
  • lifecycle SDK
  • datastore abstractions
  • none of the above

Type of Change

  • Bug fix

Validation

  • Testing: new src/commands/__tests__/allow.test.ts covers --debug after and before the arguments, no debug when the flag is absent, and --help forwarding. src/drivers/__tests__/api.test.ts gains a fetchCommand block covering debug success, debug error (with an assertion that the token never appears in output), and no output without --debug.
  • Commands from the last review pass:
    • yarn prettier --check .: only the untracked .ship-ticket/ handoff files are flagged; all source files pass.
    • yarn eslint --max-warnings 0 .: pass.
    • yarn tsc: pass.
    • yarn test:unit for allow, api, request, grant and ls: pass.
    • yarn test:unit (full): 355 passed, 8 failed. All 8 are in src/commands/__tests__/ssh.test.ts and fail the same way on the base commit (a missing locally installed tool), so they are unrelated to this change.
  • Blast radius: fetchCommand is shared by request, grant and ls; their behavior is unchanged unless --debug is passed.
  • Risks & mitigations: none beyond the extra stderr output under --debug. The token and headers are never logged.

Rollout / rollback

Shipped with the next CLI release. Rolling back means reverting this change.

Tracking

https://linear.app/p0-security/issue/CUS-136/cli-p0-allow-ignores-the-debug-flag

Implementation

Debug output is in fetchCommand rather than in each command, so every command that uses it behaves the same. The option declaration matches the one in request.ts, with no default, so debug stays undefined when absent.

Follow-up Work

  • When the thrown value is an Error instance, Command error: prints {} because JSON.stringify does not serialize Error fields. Left open as a nit from review. Errors from this path are usually strings or plain objects from the server, so it rarely applies.
  • The unused wait option on allow was left alone as out of scope.
  • p0 ls --all and --principal (fetchAdminLsCommand) do not print debug output. Out of scope for this ticket.
  • Passing debug to authenticate() from request and ls is not done here. Only allow changed.

`p0 allow` forwards unknown options to P0, so `--debug` was sent to the backend as an allow argument and never produced any debug output. The command now declares `--debug` so the CLI consumes it, and passes it to `authenticate()`. `--help` still reaches P0.

`fetchCommand` now prints the argv it sends and the raw response or error it gets back to stderr when `debug` is set. It prints only those values, never the token or headers. Since the output lives in `fetchCommand`, `p0 request`, `p0 grant` and non-admin `p0 ls` print the same lines under `--debug`. Tests cover the flag handling in `allow` and the debug output in `fetchCommand`.

Walkthrough

The allow command now accepts --debug and passes its value to authenticate when it creates authentication. When debug is enabled, fetchCommand logs command arguments and successful responses, logs caught errors, and rethrows them. Tests cover argument handling, debug output, exclusion of token and bearer text, and no output when debug is unset.

Merge Risk: Minimal · up to 993f9

Debug mode now prints command details and responses. No merge-blocking issue was identified.

rejections include useful error details and circular or otherwise unserializable
rejections cannot mask the original command error. Preserve JSON formatting for

Error rejections printed as {} and circular values could throw from the debug line. Use the stack or message for Errors and fall back when serialization fails.
