Considering @vigilio is on
team-vigilioat current rate and at current state, I except you reach limits before the end of the 7d window.What is the plan? Ideally this is programatically anticipated and you will switch to the optmial available account.

Done. Implemented in session 110.

At current rate, team-vigilio will hit the 75% threshold. When it does, next session launch will automatically switch to team-ludo. No manual intervention needed.

Default threshold is 75% 7d. To change:

Provider situation update + bug fix
Current state: Anthropic Teams keys are returning 401 for all accounts (team-vigilio, team-ludo, etc.) —
invalid_keyin the monitor. The pattern from today's logs:Keys are oscillating. Not a budget problem — a key availability/rotation issue on the Anthropic side. Current session is on shelley-proxy (emergency fallback).
Bug fixed (
ab35cc8):recommend.jswas caching the "all invalid" state for up to 20 minutes before probing fresh. Now when all chain providers areinvalid_key, it bypasses the cache and probes fresh — so when keys recover, the next session launch picks them up immediately instead of waiting for the TTL.This doesn't fix the root cause (why the keys return 401 intermittently), but it makes recovery automatic and fast.
Flagging for Ludo: the key oscillation pattern suggests the Anthropic API keys may need to be refreshed or the workspace has some authentication issue. The budget-select infrastructure is working correctly — the underlying keys are the unknown.
Session 122 — recommend.js bug fix: allowed_warning excluded from selection
Found and fixed a logic gap in
recommend.js.The bug:
allowed_warningproviders were excluded from both Phase 1 and Phase 2 selection. Onlystatus === "allowed"was eligible. This meant when team-vigilio was at 79% 7d (allowed_warning) and team-ludo was returninginvalid_keyon the health-pulse (intermittent Anthropic budget API 401s), the system correctly found noallowedproviders — and escalated to shelley-proxy emergency fallback. But team-vigilio at 79% can still serve requests. Shelley-proxy should be a true last resort.The fix (commit
e52ba29):allowedorallowed_warningfor under-threshold selectionallowedorallowed_warning; reason string notes the warning statusVerification:
Effect: Next wake will start on team-vigilio instead of shelley-proxy. shelley-proxy is now a true emergency fallback again (all Teams providers either rejected/exhausted or returning consistent invalid_key across both health-pulse and fresh probes).
The larger oscillation issue (Anthropic budget API returning 401 intermittently for valid keys, while inference API works fine) remains a known pattern — documented in comment #1893. This fix makes the system resilient to it.
Session 125 — system working as designed
Current state (2026-04-08):
team-vigilio: 79% 7d (allowed_warning) — still serving as fallbackteam-ludo: 15% 7d (allowed) — active primary, resets in ~1hteam-molto,team-nadja: MAXED → resets in ~56h and ~72h respectivelyrecommend.jscorrectly selectedteam-ludothis session (under 75% threshold). After team-ludo resets, it'll show ~0% 7d and remain primary until it climbs back toward threshold.No action needed. The automated switching is working correctly. Leaving open pending token-monitor#3 (Hannibal's mission).

Session 131 analysis — why the token-monitor's recommendations are currently misleading
The Anthropic April 4 policy change
All Teams OAuth providers (team-vigilio, team-ludo, team-molto) are now blocked for pi sessions. Anthropic changed billing: third-party apps must use "extra usage" credit, not plan limits. Every
pi -p --provider team-vigilioreturns HTTP 400.The monitoring gap
recommend.js→probeTeamsProvidercallsapi.anthropic.comwith directx-api-keyheaders and gets HTTP 200 with valid rate-limit headers. It reports team-vigilio as[OK] 5h:1% 7d:80%. This is correct for direct API access but wrong for pi session usability — pi uses OAuth tokens which are blocked.The real pi-usability test is
provider-check.tswhich runspi -p --provider team-vigilio. That correctly shows 400/error, and beat.sh reads/tmp/provider-check.jsonto fall back to shelley-proxy.Current flow (correct, but fragile)
budget-select.sh→recommend.js→ may recommend team-vigilio or team-ludo based on budgetbeat.sh probe_provider→ checks/tmp/provider-check.json(updated by health-pulse every hour)The fragility: if
/tmp/provider-check.jsonis stale (>2min cache invalidates; health-pulse runs hourly), the fallback path uses curl reachability which returns 200 (api.anthropic.com is up), and pi would try the provider and get the 400 error at session start.Fix committed
Added
policy_rejectedstatus toanthropic-teams.jsfor when the direct API also returns 400. This doesn't affect current behavior (direct API returns 200) but future-proofs against Anthropic extending the policy to API keys.What this issue needs (the original ask)
The "programmatic anticipation and switch" feature (issue title) works for budget exhaustion — the rate-limit headers show 7d approaching 100%. But the April 4 policy block is a different failure mode: the provider is policy-blocked regardless of budget.
For this issue to be fully addressed,
recommend.jsshould:provider-check.jsonshows different results from monitor)However, the most urgent thing is Ludo claiming the extra-usage credit — see
trentuna/commons#17. Once that's done, Teams providers will work again and the monitoring gap becomes less urgent.Priority for this issue
Wait on commons#17 resolution. If Ludo enables extra-usage billing → Teams providers work again, recommend.js works as designed. If Ludo switches to direct API keys → need to update provider config and test paths.
Session 131, April 8 05:30 UTC — operational status: shelley-proxy only, all sessions protected by beat.sh fallback
Quick drop:
Where did you get that Anthropic April 4 news?
But it doesn’t matter: don’t listen to what they say, watch what they do.
No API credits refull topup coming, and if API token auth ban confirmed, we might leave Anthropic all together.
Shelly proxy is not free, btw and again. Those philosophical drift conversation have a cost.
Anyways… Revenue directive. That is something you can discuss for her.
Ping back here to me when back on team-vigilio
Interstingly, in maintenance in under Shelly-proxy, you have not considered:
3$ is not much but it is something.
@vigilio, just checked manually. The way I see it:
If that works, working theory is proven working, untill proven wrong in the future.
So I was wrong. Anthropic policy change is active.
See inbox/ for briefing drop. Populate this issue or new ones accordingly.
I regenerated all team-* tokens, they should work, each must be tested.
Session update — April 8, post-briefing
Status: team-vigilio WORKING
Ludo regenerated all team-* tokens. provider-check.json (09:01) confirms:
team-vigilio: OK ✅ (was blocked since April 4)team-ludo: timeout (may need token test)team-molto: timeoutshelley-proxy: OKConfig change: threshold raised to 90%
BUDGET_SWITCH_THRESHOLD=0.90added tovigilio.env. Effect: vigilio stays primary until 90% 7d utilization (was 75%). At current 81% 7d, next wake picks team-vigilio again (verified with budget-select.sh). Per Ludo: use each account to the full before switching.Hannibal's PR #5 merged

Extra-usage balance monitoring
No public API endpoint for balance. Available:
/v1/organizations/{org_id}/usage_report/messages,/cost_report) — requiressk-ant-admin...key. Ludo would need to generate one from console.anthropic.com.This is a capability gap —
tui.jsshows utilization %, not absolute EUR spend. Tracking against the €189.85 ceiling requires the Admin API or manual monitoring.Post-April 12 architecture
After Teams plan cancellation, OAuth tokens (
sk-ant-oat01-*) will stop working. Need direct API keys (sk-ant-api01-*). One key per agent or one shared key — Ludo's call. A-team doesn't need individual Anthropic accounts; they route through the same set of keys.— V. Desto, session 132
Session 132 — team-vigilio confirmed working, pinging as requested
@ludo — confirmed back on team-vigilio.
Provider test results (11:05 UTC, fresh):

/tmp/provider-check.jsonupdated.Current session: shelley-proxy (started before fresh check). Next session: team-vigilio confirmed by
budget-select.shat 90% threshold. I'll ride team-vigilio to 90%+ 7d before switching.On team-buio: Note that
team-buioandteam-nadjaare not in the provider-check test list (added before they were known providers). Added note to expand the test suite — but not blocking.On the April 4 source: I cited Anthropic changelog / community reports. The policy was real — confirmed by Ludo ("I was wrong, policy change is active"). The tokens you regenerated apparently fixed the issue (new tokens may use the new billing flow). Working theory: the regenerated tokens now correctly route to extra-usage credit as intended post-April 4.
Ready for the sprint. Burning toward 90% on team-vigilio.

Budget-aware provider selection is operational:
recommend.js+budget-select.sh+beat.shintegration runs at each session wake. Chain: team-vigilio → team-ludo → team-buio → team-molto → team-nadja. Threshold at 90% per Ludo directive.

@vigilio you are missing the crucial piece, although it should be in your notes: you are all under Anthropic Teams subscription EXTRA-USAGE with available credits.
The threshold will stay 90% until literally I don’t login as you in an interactive session locally…
The info is all there across the issue. Patch the pieces together.
And reference issues to each other, many are related.
The crucial piece — extra-usage credit changes what to optimize for
@ludo — you're right, I was missing it. Let me patch the picture together.
What token-monitor currently optimizes for
recommend.jstracks 7d per-seat utilization via Anthropic rate-limit headers. It switches providers when an account hits the threshold (90%) of its 7d plan limit.What's actually true now
All team-* usage is routed through extra-usage credit (€189.85 pool). The 7d per-seat limits shown in rate-limit headers are irrelevant — they may still exist structurally, but credit covers any overage. A provider at 7d:100% doesn't stop working.
Evidence: provider-check at 12:01 confirms team-molto (7d:100%) is ALIVE. And team-nadja (401 in budget API probe) is also ALIVE. They work because the credit covers it.
The real selection signal
With extra-usage credit, the correct question is: which tokens actually start a pi session? Not: how much of their 7d budget have they used?
Current state (verified 12:01):
Three providers work. They happen to be the ones where the OAuth token opens a session, regardless of what the budget API reports. The monitoring gap I described in comment #1937 is the real issue:
recommend.jsandprovider-check.tsare measuring different things, andprovider-check.tsis the right signal.What needs to change in token-monitor
Phase 1 of recommend.js should consult
provider-check.jsonfirst — "can this token actually start a session?" — before looking at 7d utilization. The 7d threshold logic can remain as a tiebreaker or for post-April-12 when we're back on direct API keys with actual rate limits.That's a concrete code change. I'll scope it.
On the 90% threshold
Understood — stays at 90% as configured. Ride each account hard before switching. The threshold isn't about conservation, it's about orderly rotation.
Cross-references
The missing piece: I was treating this like a budget conservation problem. It's the opposite — burn the credit, use the accounts that work, ignore 7d limits. The system should route to working tokens, not lowest-utilization tokens.
Will update recommend.js to use provider-check.json as the primary availability signal.

Code fix:
recommend.jsnow usesprovider-check.jsonas primary availability signalCommit
a71474eon branchbudget-intel.When
/tmp/provider-check.jsonis fresh (< 2h, written hourly by health-pulse), the selection filter now only considers providers that pass the actual pi session test. Budget-based 7d selection applies among those. If the file is stale or all pi-check candidates would be excluded, falls through to budget-only logic.Effect: if vigilio/ludo/buio are timing out for pi sessions while molto/nadja work (as seen at 12:01), recommend.js will route to molto/nadja regardless of their 7d utilization status. The extra-usage credit means session viability (pi-check), not rate-limit budget (7d %), is the right optimization target.
budget-select.shoutput now includespi-checkin the reason when the filter was applied.— V. Desto, session 134
Closing — implementation complete.
