A slow drain (goals SQL retrying behind a stalled network) would have taken the whole output with it. Stop waiting at 4s; notifications that land after that go back on the queue for the next session rather than being marked shown and never rendered. Surfaced by tests/codex/codex-integration.test.ts flaking under a loaded full-suite run: it executes the real bundle as a subprocess and inherited the developer's HOME, so with real credentials present the hook made live API calls and blew its 15s timeout.

A dead link at the moment the user needs to top up defeats the notice. The API exposes no slug (/organizations/{id} returns only id + display name), so key on the UUID. - 'Credits exhausted' was queue-only: written when a 402 fires, drained at the NEXT SessionStart. So the session that broke said nothing ('no billing messages in codex, so I don't know I finished the money'), whichever agent started next ate the single queued copy, and after an org switch the stale copy named the wrong org and linked to its billing page. Decide it from the live balance read instead, which is scoped to current credentials; the live notice supersedes a queued one with the same id. The 402 queue path stays as the fallback when the balance read itself fails. - 'SessionStart hook (failed) error: hook timed out after 10s' - Codex discards the ENTIRE hook output on timeout, losing the login context and the billing CTA together. Bounding just the drain missed the auto-pull, the org-token heal and module init. Add a hook-wide budget that emits a minimal correct output rather than letting Codex drop everything. --- src/deeplake-api.ts | 26 ++++++---- src/hooks/codex/session-start.ts | 46 ++++++++++++++++- src/notifications/index.ts | 12 ++++- src/notifications/sources/low-balance.ts | 51 +++++++++++++++---- .../notifications-low-balance.test.ts | 28 +++++++--- tests/codex/codex-notifications-merge.test.ts | 29 +++++++++++ .../deeplake-api-balance-exhausted.test.ts | 5 +- 7 files changed, 167 insertions(+), 30 deletions(-) diff --git a/src/deeplake-api.ts b/src/deeplake-api.ts index 8740bb59a..bef609a55 100644 --- a/src/deeplake-api.ts +++ b/src/deeplake-api.ts @@ -139,20 +139,26 @@ function maybeSignalBalanceExhausted(status: number, bodyText: string): void { } /** - * Construct the org-scoped billing URL from persisted credentials.

Cursor and Hermes are now covered; Pi is not (see below). Neither harness has a user-visible session-start channel, verified rather than assumed: - Cursor (cursor-agent 2026.08.11): a marker probe wired into ~/.cursor/hooks.json shows only top-level additional_context survives, and only into the MODEL. systemMessage, nested hookSpecificOutput and stderr are all dropped. - Hermes: on_session_start's return is discarded upstream, and _parse_response in agent/shell_hooks.py honours {"context": ...} for pre_llm_call alone. Delivered from the already-registered pre_llm_call capture hook, so no config change and no re-consent prompt; a sentinel keeps it to once per session. So on these agents the only route to the user runs through the model, which forces a different rendering: billing notices go out as a statement of fact ('credits are exhausted; capture and recall are disabled'), never as the imperative aimed at the user ('Top up at to keep capturing') that reviewers flag as a prompt-injection shape. Only our own statically-authored billing copy is eligible - mined insights and backend pushes stay out. Verified in real sessions of each harness.

Verified against the installed @mariozechner/pi-coding-agent typings (dist/core/extensions/types.d.ts) and its docs/extensions.md. I previously recorded pi as having no user-visible channel. That was wrong, and wrong in an avoidable way: I inferred it from what our own extension happened to do (inject context through a static ~/.pi/agent/AGENTS.md) instead of reading pi's API. So unlike Cursor and Hermes, a pi user can simply be told - no relaying through the model, no status-line rewrite. The extension is raw TS with no non-builtin imports, so the drain runs in a bundled worker (src/hooks/pi/notifications-worker.ts) whose stdout the extension reads and feeds to notify(), one toast per notification with our severity mapped onto pi's. Same spawn pattern as autopull. Verified in a real pi TUI session: Warning: credits exhausted - top up to keep capturing Sessions are not being saved and memory recall is returning empty. Top up at https://deeplake.ai//workspace/default/billing ...
