active plan not found for plan %s and branch %s

Error message

active plan not found for plan %s and branch %s

What it means

genPlanDescription needs the active plan (for its context, session ID, and cancellation scope) before generating a plan/commit description via the LLM. When GetActivePlan returns nil for the plan ID + branch, it notifies and returns a 500 ApiError. The description cannot be generated without the live plan session.

Solutions

1. Verify the planId and branch match the currently streaming plan (GET the plan's status first)
2. Retry the tell request so the plan is re-activated before description generation
3. Check server logs for an earlier Stop or DeleteActivePlan call for this plan
4. Report/persist a description fallback so a finished plan doesn't lose its commit message

Example fix

// before
desc, apiErr := state.genPlanDescription()
// after: check the plan is still active first
if modelPlan.GetActivePlan(planId, branch) == nil {
    log.Println("plan no longer active; skipping description")
    return
}
desc, apiErr := state.genPlanDescription()

// ensure plan is streaming before asking for a description
resp, _ := http.Get(baseURL + "/plans/" + planId + "/" + branch + "/status")
// only proceed if status indicates an active/streaming plan

desc, apiErr := state.genPlanDescription()
if apiErr != nil && strings.Contains(apiErr.Msg, "active plan not found") {
    log.Printf("plan %s/%s deactivated before description; skipping", planId, branch)
    return
}

When it happens

Trigger: The tell stream that should have registered the active plan has ended (finished, errored, stopped, or deleted via DeleteActivePlan) before genPlanDescription runs; or the planId/branch pair passed to the stream does not match any registered active plan.

Common situations: Plan finished extremely fast and was deactivated before the description step; concurrent Stop request during streaming; using a stale planId after a server restart; branch name typo in the API call.
