The Croft Retainer Trap: Why Agencies Fail When AI-Built Client Apps Outgrow the 7-Day Log Window
Symptom: A client reports a checkout failure that happened nine days ago, and the Croft dashboard returns nothing because searchable logs only retain 7 days. Root cause: Croft keeps 7 days of searchable logs, which is shorter than most agency incident-review cycles. A bug reported at the next monthly client call is already outside the retention window, so root-cause work depends on whatever the client's AI assistant captured in the moment.

How do you recognize it?
- •A client reports a checkout failure that happened nine days ago, and the Croft dashboard returns nothing because searchable logs only retain 7 days.
- •The client's own Claude or ChatGPT session can read Croft errors over MCP, but the agency's delivery lead cannot reproduce the fix because the stack trace has already aged out.
- •Alert emails fire on every error group, and nobody on the retainer has defined which groups are client-critical, so the inbox becomes noise within two weeks.
- •A second client app is stood up on the same Croft account and the shared data setting quietly exposes one client's connector data to the other's builders.
- •The agency bills a monthly retainer but the client's Team plan caps at 50 people, so the client's own contractors start asking for seats the agency never scoped.
Why does it happen?
- •Croft keeps 7 days of searchable logs, which is shorter than most agency incident-review cycles. A bug reported at the next monthly client call is already outside the retention window, so root-cause work depends on whatever the client's AI assistant captured in the moment.
- •MCP diagnostic tools are designed for the AI assistant that built the app, not for an agency engineer joining later. If the agency never connects its own assistant to the client's Croft server, the fix path runs through the client's tooling and the agency loses delivery control.
- •The Solo plan at $24/month shares data across your own apps and allows up to 10 people, while Team at $99/month raises that to 50 people with roles and permissions. Agencies that resell Solo to multiple clients on one account inherit cross-client data visibility that no retainer contract anticipated.
- •Croft's monitoring covers error grouping, response-time profiling, throughput, failure rates, slow SQL, and health checks, but it does not replace an escalation process. Agencies that treat the built-in alerts as the whole on-call layer have no defined owner when an alert fires at 2am.
How do you fix it?
- •Open the Croft dashboard for each client app and export or screenshot the current error groups and slow SQL entries into the client's ticket before the 7-day window closes, so the agency keeps a durable incident record.
- •Connect the agency's own Claude or ChatGPT instance to the client's Croft server over MCP and verify it can read errors, metrics, and logs, then make that connection part of the onboarding checklist rather than the client's responsibility.
- •Audit which Croft plan each client sits on. Move any client with more than 10 named users or any need for role separation from Solo at $24/month to Team at $99/month, and reprice the retainer to cover the difference.
- •In the Croft alert settings, route notifications to a shared agency inbox and assign one named responder per client app, then review the error groups weekly and close or mute the ones that are not client-impacting.
