Problem

Devin is available as an ACP Registry provider, but Usage shows neither its remaining subscription allowance nor its token use and cost. ACP exposes neither.

Change

Limits. Read the remaining daily and weekly allowance and reset times from GetUserStatus using the Devin CLI's login, including Windows AppData. Plans that hide daily quota show only the weekly allowance, and the same account counts once across environments. Disabled Devin instances read no credentials and make no quota request. The quota request refuses redirects, so the API key in its body can't be sent anywhere but the API server. Missing credentials, unsupported billing, and failed requests show as unavailable.

Cost and Tokens. Read Devin CLI's saved session history into the same token and cost tracker the other providers use. Both models in Fusion sessions count. Costs use the model prices the installed Devin CLI reports. Models with no known price still add tokens and show as unpriced. A large first scan can take minutes, so totals appear as sessions finish. Completed sessions are saved during the scan, so refreshes and restarts read only new messages.

4	UsageService
5	merges Devin records, prices via the Devin model rates
6	Usage page (web, desktop, mobile)
7	"devin" provider: name, logo, model filter

Scope and approval

This adds usage reporting for the existing Devin provider. The Devin team has given the author the go-ahead for the integration. No T3 maintainer approval link has been provided yet.

Related and overlapping work, for comparison:

#26381 adds a Devin dashboard link. This PR fills the existing quota bars and cost charts instead.
#29631 also adds Devin Cost and Tokens from the local sessions database.
realhasanshoaib/t3code#1, stacked on #26381, adds Devin Limits.

Verification

Windows desktop, real Devin account: Limits shows 63% weekly remaining with the Devin logo and reset countdown. Cost shows 139 Devin sessions, 5.15B tokens, alongside the other providers. No paid agent turn was run.
Restart after the first scan: the Devin history read took 0.23 s and reread 0 messages.
Tests: the quota-reader tests cover Windows AppData, the removed dashboard row, out-of-range reset timestamps, icon retention during account dedup, and the quota request refusing redirects (that assertion fails with the setting removed). New devinUsage.test.ts covers the history reader. UsageService.test.ts and serverUsage.test.ts cover the merge and progressive totals.
vp run check:changed on ec44e4e07b's tree passed format, lint, knip, typecheck (36 packages), tests (17 files) and the React Compiler check.
macOS: @vxirau reports the same GetUserStatus request returns correct daily and weekly values with a real Devin Pro account (Devin CLI 3000.11.228).
Native mobile and Linux live accounts were not exercised. Mobile adds the Devin provider entry on the shared contract.

Disabled Devin instances still read local credentials and send an authenticated GetUserStatus request, because checkUsageLimits runs before its result is discarded for disabled providers. Gate creation of the probe on enabled so the read never executes for disabled instances.

Note

🤖 Devin (Claude Opus 5.5) responding on behalf of screen-gd

Fixed in 108d0d52b3. checkUsageLimits in packages/provider-acp-registry/src/server/driver.ts is now built only when effectiveConfig.enabled is true. A disabled Devin instance no longer reads credentials.toml or sends its key to GetUserStatus. The existing provider.enabled && provider.installed check on the merged result is unchanged.

No test was added. driver.test.ts tests only the readiness and status helpers and never builds the full driver layer, where this check lives.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Devin accounts gain automatic authenticated quota retrieval and daily/weekly usage displays. Human review is needed for this default behavior change, particularly the reported credential-backed requests from disabled instances.

Walkthrough

The changes add Devin usage-history scanning, model pricing, and allowance checks. They update provider-rate handling, client refresh behavior, and web and mobile usage displays. Limits pools can show account names and icons, and the usage documentation describes Devin support.

Changes: Devin usage and display

Layer / File(s)	Summary
Devin history reader and cache `packages/provider-acp-registry/src/server/devinUsage.ts`, `packages/provider-acp-registry/src/server/devinUsage.test.ts`	The reader scans Devin session databases, parses CLI model prices, assembles usage records, and manages persisted caches and scan refreshes. Tests cover history, caching, pricing, and read errors.
Usage contracts, pricing, and server wiring `packages/provider-core/src/server/usage.ts`, `apps/server/src/usage/*`, `apps/server/src/server.ts`, `apps/server/src/provider/builtInDrivers.ts`, `apps/server/src/usage/UsageService.test.ts`	Provider scans can include model-specific rates. The usage service overlays provider rates on shared rates, and the server registers Devin usage services. A service test checks Devin totals and price overrides.
Devin allowance lookup and driver integration `packages/provider-acp-registry/src/server/devinUsageLimits.ts`, `packages/provider-acp-registry/src/server/devinUsageLimits.test.ts`, `packages/provider-acp-registry/src/server/driver.ts`	The allowance reader loads Devin credentials and queries the seat-management API. The driver applies returned limits to eligible registry-backed Devin providers. Tests cover credential selection, quota responses, and unsupported cases.
Usage refresh completion `packages/client-runtime/src/state/server.ts`, `packages/client-runtime/src/state/serverUsage.test.ts`	The client requests further summaries while a usage source is refreshing. It emits interim summaries and stops when sources finish refreshing or a refresh request fails.
Provider labels, account icons, and documentation `packages/contracts/src/usage.ts`, `apps/mobile/src/features/usage/usageProviders.ts`, `apps/web/src/components/usage/*`, `packages/shared/src/usageLimits.ts`, `packages/shared/src/usageLimits.test.ts`, `docs/user/usage.md`	The usage interfaces add Devin labels, chart and provider presentation, and loading feedback. Account records carry and merge icon URLs. The documentation describes Devin history, pricing, filtering, and allowances.

Full details: Description check

Explanation

The description covers the Problem, Change, Scope and approval, and Verification sections. The Problem and Change sections are clear. Scope and approval is incomplete: the author states the Devin team gave the go-ahead, but no T3 maintainer approval link or comment is provided, and the template requires one for a feature of this size. Verification is substantive, with Windows desktop results, test coverage, a macOS report from another contributor, and before/after screenshots. The Verification section also says native mobile and Linux live accounts were not exercised, which the template asks for. The description also includes an AI-agent attribution line, which the template asks for. The remaining gap is the missing maintainer approval.

Resolution

Add a link to the triaged bug issue or to a discussion where a T3 maintainer explicitly approved the direction and scope, including the approval comment. The current text says 'No T3 maintainer approval link has been provided yet,' so this link is required. Keep the existing Verification section, which already lists what was not checked.

Bound the reset timestamp before DateTime.makeUnsafe.

resetAtIso accepts any finite positive value. A value above the JavaScript Date limit of 8.64e12 seconds makes DateTime.makeUnsafe throw. Because the throw happens in the Effect.gen body, it is a defect. Effect.orElseSucceed handles only failures, so the defect is not converted to probeFailed. The defect fails the Devin checkProvider effect, so that snapshot refresh stops and the previous snapshot remains. The failure repeats on each refresh while the upstream value stays malformed.

Bound the value so the helper returns undefined for out-of-range input.

Note

🤖 Devin (Claude Opus 5.5) responding on behalf of screen-gd

Fixed in 108d0d52b3. resetAtIso in packages/provider-acp-registry/src/server/devinUsageLimits.ts now calls DateTime.make. In effect 4.1.2 that is Option.liftThrowable(makeUnsafe), so an out-of-range timestamp yields a window without resetsAt instead of a defect that orElseSucceed cannot catch.

I added a row to the existing it.effect.each table with dailyQuotaResetAtUnix: "99999999999999". Before the fix it failed with IllegalArgumentError: Invalid date; now it passes.

@screen-gd Confirmed in the current code. resetAtIso now uses DateTime.make and converts None to undefined, so an out-of-range timestamp no longer causes the reported defect.

The regression case checks that "99999999999999" leaves the daily window without resetsAt and preserves the valid weekly reset. This addresses the finding. I inspected the code and test; I did not run tests.

Preserve iconUrl during account deduplication.

When the same account is reported by multiple environments, a later next record can contain iconUrl while previous does not. Lines 301-317 spread previous but never copy next.iconUrl, so the UI can fall back to the generic icon based on presentation order.

Add iconUrl: previous.iconUrl ?? next.iconUrl to the merged account. Extend the existing collectLimitAccounts deduplication test with this case.

As per path instructions, keep the regression test at the lowest applicable layer.

Fixed in 108d0d52b3. When collectLimitAccounts in packages/shared/src/usageLimits.ts merges duplicate accounts, it now sets iconUrl: previous.iconUrl ?? next.iconUrl. A later environment's icon is no longer lost.

I extended the existing cross-environment dedup test: only the second environment reports iconUrl, and the merged account keeps it. The assertion failed before the fix.

CcoderabbitaiBot7d ago

@screen-gd Thanks for the fix. The supplied code now uses previous.iconUrl ?? next.iconUrl, so a later environment’s icon is retained when the earlier record has none. The regression test you described covers the reported failure case.

Gate the Devin usage check on effectiveConfig.enabled.

The condition checks only source and agentId. A disabled Devin instance still runs readDevinUsageLimits. It reads credentials.toml and sends the API key to the Devin server on each refresh. The driver then discards the result at Line 614, because provider.enabled is false.

A user who disabled the provider does not expect network calls with its credentials. Add the enabled check to the condition.

🤖 Devin (Claude Opus 5.5) responding on behalf of screen-gd

No test was added. driver.test.ts tests only the readiness and status helpers and never builds the full driver layer, where this check lives.

Checks on this head: vp run check:changed passed (format, lint, knip, typecheck of 34 packages, 79 tests).

CcoderabbitaiBot7d ago

@screen-gd The supplied code confirms the fix. When effectiveConfig.enabled is false, the driver does not build or schedule the Devin usage check. The registry-source, Devin-agent, and merged-result guards remain intact.

This addresses the reported concern. I have not independently run the reported checks.

🤖 GPT-6.1 Sol responding on behalf of screen-gd

Rebased onto main at e27e12d9b4a4 and pushed 35d0acb690 with an explicit force-with-lease.

The conflict was in packages/provider-acp-registry/src/server/driver.ts: upstream added Effect's Digest service while this PR added HttpClient. Both requirements are retained. The Devin quota reader now uses Digest.sha256, and its tests explicitly provide NodeCrypto.layer, matching upstream's Effect 4.1.2 migration.

The commit-range comparison preserves the quota reporting, Windows credential path, Devin logo, and removal of the redundant dashboard row.

Validation: vp run check:changed e27e12d9b4a408496be359e3e0db1844c6ea87af passed formatting, lint, both unused-code checks, all 34 affected-package typechecks, and 78 tests. The separate quota-reader run passed all seven tests, including the unchanged credential fingerprint. A live reader request still reported 63% weekly remaining with no dashboard row. The React Compiler check's tests were skipped, so compiler coverage is not claimed. The app was not launched.

Verified in a real dev environment

partial verification of head 35d0acb6902529e7965ca5f941c6fd4ebff7c3ad on a linux vm, using the repo's playwright and /usr/bin/google-chrome at 1440×1000. no source changes.

started github/main (3d369d55968b) in a separate worktree first, then stopped it before starting the exact pr head. used isolated state, added /home/user/t3code as a project through the app, installed devin from the live acp registry (3000.11.234), and ran real codex gpt-6.1-sol turns through the web client and local proxy on both revisions.

the real server-config subscription showed this difference for the installed, enabled devin provider:

text

1	main: installed=true, status=ready, usageLimits=null
2	pr: installed=true, status=ready,
3	usageLimits.windows=[],
4	usageLimits.unavailable={reason:"unsupported",
5	message:"Sign in to Devin to see usage limits."}

this verifies the new reader's missing-credentials path through the running server and client. limits refresh completed without quota bars. continuing the existing codex thread completed successfully on the pr; switching between tokens and limits also worked. codex quota retrieval reported JSON-RPC -32600 on both main and the pr through this proxy, so that error is a baseline limitation.

matching installed-but-signed-out limits captures follow. neither image proves authenticated devin bars.

main: installed devin without credentials has no limits entry

pr: missing devin credentials safely produce no quota bars

focused existing quota-reader, acp-driver, and shared-limits tests passed on blacksmith: 76 tests across three files. vp run check:changed e27e12d9b4a408496be359e3e0db1844c6ea87af also passed all stages, including 78 tests across five files and the changed-file react compiler check, after installing the worker's missing browser dependency.

Not verified

this vm has no devin login. successful authenticated quota retrieval, daily/weekly percentages, hidden-daily plans, reset countdowns, account deduplication, and external api failures remain unverified through a real account. this is not end-to-end proof of the main feature or a merge recommendation.

native mobile, electron shell, windows appdata, macos credentials, and multi-environment behavior were not exercised. no mocks, fabricated credentials, fixtures, or replay-provider turns were used.

fix(usage): skip Devin quota reads when disabled and harden merge108d0d5

Note

🤖 Devin (Claude Opus 5.5) responding on behalf of screen-gd

@maria-rcks thanks for the run. Pushed 108d0d52b3 with three review fixes. None changes the signed-out path you verified:

Disabled Devin makes no requests. driver.ts now starts the quota read only for enabled instances. Before, a disabled instance still read credentials.toml and sent its key to GetUserStatus, then dropped the result.
Out-of-range reset timestamps no longer break refresh. resetAtIso uses the non-throwing DateTime.make, so a bad value shows the bar without a reset time. Before, it raised a defect that stopped the provider check on every refresh. Covered by a new row in devinUsageLimits.test.ts.
Account dedup keeps the icon. collectLimitAccounts now takes iconUrl from either environment. Covered by an extra assertion in the existing dedup test.

vp run check:changed passed on this head (format, lint, knip, typecheck of 34 packages, 79 tests).

Your "not verified" list still stands: the signed-in quota bars, hidden-daily plans, reset countdowns, cross-environment dedup with a real account, and native/desktop/Windows/macOS paths have not been exercised end to end on this head.

Note

🤖 Devin (Claude Opus 5.5) responding on behalf of screen-gd

Not adding this test in this PR. No test builds AcpRegistryDriver today; driver.test.ts covers only the readiness and status helpers. A disabled-instance case would need a new harness for the full driver layer (catalog, runtime coordinator, spawner, filesystem, HTTP client, digest) to cover one boolean in the checkUsageLimits condition. That's out of proportion for this PR.

The behavior lives in a single condition: effectiveConfig.enabled && source === "registry" && agentId === "devin". If driver-level coverage is wanted, it belongs in a follow-up that adds a reusable driver harness.

CcoderabbitaiBot7d ago

@screen-gd Understood. The supplied code sets checkUsageLimits to undefined when effectiveConfig.enabled is false. It then omits the usage-limit callback from makeManagedServerProvider.

The missing driver-level test does not establish a security defect. My Major / Security & Privacy classification was not justified. I withdraw this as a required change for this PR.

Would you like a follow-up issue for a reusable driver test harness and disabled-instance coverage?

feat(usage): track Devin tokens and estimated costb011ee9

SScreen6d ago

Note

🤖 Claude Opus 5.5 responding on behalf of screen-gd

Pushed b011ee9196: Devin now appears in Usage's Cost and Tokens views, not only Limits.

packages/provider-acp-registry/src/server/devinUsage.ts reads Devin CLI session history (Fusion sessions count both models) and prices it with the Devin CLI's model rates. Unknown models count tokens and show as unpriced.
Totals appear as sessions finish. Progress is saved, so a restart after the first scan reread 0 messages in 0.23 s on a 139-session history.
devin added to UsageProviderKind, web and mobile provider lists, the model filter and docs/user/usage.md.

Checks on this tree: vp run check:changed passed format, lint, knip, typecheck (36 packages), tests (12 files) and the React Compiler check. Two GPT-6.1 Sol review rounds approved with no findings. Still not exercised: native mobile, and live Linux/macOS accounts.

External image Unverified finding Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Remove the hard INDEXED BY idx_message_nodes_session dependency on Devin's schema.
Devin CLI owns sessions.db, so this reader does not control the index name. In SQLite, INDEXED BY makes the statement fail with a "no such index" error when the named index is absent. A later Devin release could rename or drop idx_message_nodes_session. The query would then raise SqlError, and read would map it to error: true. Every Devin source would then show "Some Devin history could not be read." with no new history.
The SQLite planner already selects a session_id index when one exists, so the hint adds no needed behavior. Only the test fixture establishes this index name.

Proposed fix

1 - "SELECT session_id, count(*) AS row_count, max(row_id) AS last_row_id FROM message_nodes INDEXED BY idx_message_nodes_session GROUP BY session_id",

Preserve Devin's identity in the mobile usage mapping.

UsageLimitsSection passes the provider driver, not a usage-provider key, to usageProviderKind. Devin uses acpRegistry, so the helper returns null and the usage bar does not receive the Devin color. Resolve Devin using its agent identity or pass the usage-provider key before applying the color. Do not map every acpRegistry provider to "devin" because that driver is shared by other agents.

🤖 Devin (Claude Opus 5.5) responding on behalf of screen-gd

Fixed in 9b19a86c66. On mobile, usageProviderKind in apps/mobile/src/features/usage/usageProviders.ts now maps acpRegistry to "devin", so Devin's limit bars in UsageLimitsSection and UsageLimitsPooled get Devin's color. Before, they fell back to no color or the Codex color.

Mapping by driver instead of agent identity is deliberate. It matches web, where barColor resolves acpRegistry to the devin entry in PROVIDER_PRESENTATION. On mobile, usageProviderKind is used only for limit bars, and Devin is the only ACP Registry agent that reports limits (checkUsageLimits in driver.ts), so no other agent picks up this color. If a second registry agent ever reports limits, web and mobile both need agent-level identity, and that change belongs in its own PR.

vp run check:changed passed: format, lint, knip, typecheck of 36 packages, and 17 test files.

@screen-gd Verified the mapping and both mobile limit-bar callers. The driver enables checkUsageLimits only for enabled Devin registry instances, so other registry agents do not receive Devin-colored limit bars.

The color fix is present. I withdraw the requirement to use agent-level identity in this PR. That distinction becomes necessary if another registry agent adds usage limits.

Bound the awaitRefresh follow-up loop.

The Devin reader waits for one progress event, not necessarily for scan completion. If the scan remains active, it returns refreshing: true. The client then immediately sends another serverGetUsageSummary request. Repeated progress events can therefore keep this loop running for a long scan and generate many follow-up RPCs.

Add a maximum number of follow-ups, for example 64. After the limit, return the last summary.

🤖 Devin (Claude Opus 5.5) responding on behalf of screen-gd

Not adding a cap. The loop isn't unbounded or hot:

Each follow-up with awaitRefresh: true blocks on the server. Devin's history waits on active.changed (devinUsage.ts ~L620), and that resolves only on a progress event or when the scan exits.
readDevinUsage publishes progress after the first session and then every 8th (~L457). The scan's onExit clears scans and resolves the final deferred, and the next response then has no refreshing. So the loop ends when the scan ends, and it makes about sessions / 8 requests in total, paced by real work.
Cursor doesn't multiply these requests. awaitRefresh there only waits for a refresh already in progress or started when the cache is stale (isCursorCacheFresh, failure TTL), so repeated follow-ups don't refetch.
A request error still returns the last summary and stops.

A fixed cap of 64 would stop progressive updates partway through a large Devin history. The page would then show partial totals still marked as refreshing until the 60-second stale refetch, which goes against the point of the change ("totals appear as sessions finish").

@screen-gd You're right. I checked DevinUsage.history and the scan cleanup. Each awaited follow-up waits for a progress event or scan exit. Scan cleanup removes the active scan and releases the final waiter.

My recommendation confused progress-driven follow-ups with a hot polling loop. A fixed cap of 64 could stop updates before the scan completes and leave partial totals displayed. The client also already stops on a follow-up request error.

I withdraw the cap recommendation. No change is needed for this finding.

Include the model in the Devin request-ID dedupe key.

The dedupeKey for rows with a request ID omits the model. The seen set is shared across all sessions. If one request ID appears on rows for two models, as Fusion lead and sidekick turns can if Devin writes them that way, the second model's tokens and cost are skipped. This can undercount Fusion sessions against the PR goal of counting both models.

The model is already resolved at devinUsage.ts:258, before the key is built. Adding it keeps same-model duplicate suppression, such as forked sessions, and keeps distinct models separate.

🤖 Devin (Claude Opus 5.5) responding on behalf of screen-gd

Not changing the key. I ran a read-only check against a real Devin sessions.db (13 GB, Fusion lead and sidekick sessions included), using the same JSON paths the reader uses:

145,138 assistant rows across 30,429 request IDs, every one with generation_model set.
0 request IDs span more than one model, and 0 span more than one session.
28,843 request IDs have several rows with tokens, and 0 of them differ in their input/cache_read/cache_creation/output counts.

Devin writes a separate request ID per model call, and every row of one request repeats the same metrics. devin:${requestId} therefore already counts lead and sidekick separately and keeps exactly one copy of a request. Adding the model would change nothing on this data. It would only matter if Devin started reusing a request ID across models, and that change would show up first as a format change in the logs.

CcoderabbitaiBot6d ago

@screen-gd Your reported database check supports keeping devin:${requestId} unchanged. Separate request IDs count the Fusion models separately, while deduplication removes repeated rows with identical metrics.

My finding assumed cross-model request-ID reuse without evidence. I withdraw the finding. No key or test changes are needed for this concern.

Glad to see this, I'd love Devin in Usage too. For whoever reviews: this overlaps with realhasanshoaib/t3code#1 (Devin Limits, stacked on #26381) and #29631 (Devin Cost and Tokens), in case it helps to compare them.

One small thing worth checking: the GetUserStatus request carries the CLI's API key in the body, so it's worth disabling redirects on it (FetchHttpClient.RequestInit with redirect: "error", like Cursor's accountUsage.ts). That way the key can't be forwarded off server.codeium.com.

I tested the same endpoint on macOS with a real Devin Pro account (CLI 3000.11.228), and the daily and weekly values came back correctly, if that helps with the macOS gap in the verification.

fix(usage): stop Devin's quota request from following redirectsec44e4e

SScreen6d ago

Note

🤖 Claude Opus 5.5 responding on behalf of screen-gd

@vxirau good catch. Pushed ec44e4e07b, so the Devin quota request now refuses redirects.

packages/provider-acp-registry/src/server/devinUsageLimits.ts provides FetchHttpClient.RequestInit with redirect: "error" on the GetUserStatus call, the same way Cursor's accountUsage.ts does. A redirect now fails the request, and the reader reports "Could not read Devin usage limits." instead of resending the API key to the new location.
devinUsageLimits.test.ts checks that the request carries redirect: "error". All three quota cases fail when the setting is removed.
vp run check:changed passed on the pushed tree: format, lint, knip, typecheck (36 packages), tests (17 files), React Compiler.

Thanks for the macOS run with a Pro account. I've added it to the description's Verification section, and listed #29631 and realhasanshoaib/t3code#1 there as overlapping work for reviewers to compare. Native mobile and Linux live accounts are still unverified.
