feat(composio): rework the credential page into single-select rows

[graycyrus]

Gives the Composio credential page the same layout and flow as the reworked LLM Providers tab, and the host half it was talking to. Part of the Connections consistency pass alongside #2262 (LLM), Search and Account.

What changes

Composio is the simple case: two options, TinyHumans-managed or your own key, presented as rows rather than a mode table.

Console

• The connection rows are decided in pure modules (frontend/src/composio/{rows,classify,types}.ts) rather than inside the view, with 40 new unit tests.
• ComposioSection.tsx drops from 831 to 492 lines.
• Test is wired to the new host route on the own-account row, and only where there is a stored key to check.

Host

• ComposioStatus.managedCredentialSource — what the managed chain resolves to, independently of the stored mode. Additive; nothing existing moves.
• PUT …/composio/api-key checks the draft key before storing it, and gains skipVerify (default false) plus advisory / probeClass on the response.
• POST …/composio/api-key/test — check the stored key, change nothing.
• src/company/composio_probe.rs — a pure classifier over the probe's error text.

Why the probe is classified rather than boolean

A yes/no probe destroys working credentials. 407 Proxy Authentication Required carries the word an auth branch looks for, and a WAF's bare 403 Forbidden has the same shape — so the proxy/gateway branch runs first and answers unknown, a 403 counts as auth only alongside credential wording, and the digit tests use word boundaries so 401/403 cannot match inside an id like ca_1403. Only auth is destructive. Every other class stores the key and returns an advisory, because the key is plausibly fine and the connection is not.

There is deliberately no model class — Composio has no model concept — and describe returns a fixed string per class, so the upstream error (which can echo request headers or a key fragment) never reaches a banner.

Probe-then-store, not write-then-probe-then-roll-back

A deliberate departure from docs/modules/inference/connect-flow.md. That flow writes the credential first because its probe resolves a key by provider slug out of the store. Composio's probe takes the key directly, so a draft can be validated and a bad key is never written at all — no rollback path and no orphaned-secret failure mode. The doc's own "Testing a draft" section is where the shape comes from.

No SSRF guard, and that is not an omission. The probe's destination is the compile-time DIRECT_BASE_URL, never an operator-supplied URL, and no route accepts an endpoint. POST …/composio/api-key/test takes no body at all for the same reason.

Notes for review

• managedCredentialSource is a tier name, never a boolean about a secret slot. A tokenConfigured-shaped field was on this DTO once and was removed by capabilities: composioTokenConfigured reports false while the Composio GitHub connector works #886: it answered about one of three tiers and is routinely false on a working hosted tenant. The field's doc says so and names the issue. token and tokenConfigured stay absent from the read shape, with a test asserting the exact key set.
• Under BYOK the two source fields differ on purpose. credentialSource names the Composio key the agents present; managedCredentialSource names what the managed route would answer with. The managed chain is not resolved anywhere else on that path — fetch_catalog goes through resolve_tenant → resolve_access and dials backend.composio.dev with the BYOK key — so this takes its own resolve_credential call. Secret-store reads, no network.
• POST …/composio/api-key/test never writes, on any path, including auth. Testing a credential and withdrawing it are separate acts; a Test that cleared a rejected key would be the worst control on the page. A test asserts composio/mode and composio/api_key are byte-identical across a failed check.
• Two copy tables, deliberately. The write route's advisory says Saved, but …; the check route's verdict must not, because it stored nothing. Tests on both sides assert no verdict string says "Saved" and that the two tables never converge — this is a filed defect on the sibling LLM surface, and the tests are what stop a later deduplication reintroducing it here.
• CompanyCredentialCard no longer renders on this page (see the follow-up section below). The component itself and its Account-page caller (ApiKeyView.tsx:280) are untouched; copy changes to it still belong to the Account branch.
• The managed row keeps the name OpenHuman-managed. Reversed after live testing — it is TinyHumans-managed now. The three-payer argument was right about the sub-line and the sub-line is unchanged: managedSubline still names the payer per resolved tier. The label answers the coarser question the row asks — whose Composio account, ours or yours — and the answer to that is the company an operator has an account and a balance with.
• Test is not offered on the managed row. That route's credential is a bearer the TinyHumans backend recognises, and no cheap call tells a bad bearer apart from a backend that is down — a Test there could only report an outage as a rejected credential, which is the misclassification the whole design avoids.
• Remove key on the own-account row is the same host call as the managed row's Use this — the host derives the route from whether a key exists — so it is not rendered twice under two names.
• frontend/test/e2e/composio-catalog-deadline.spec.ts had its body retargeted to the new controls and its stale rationale rewritten, but is left skipped: un-skipping needs a Console E2E lane run that could not be performed locally. Deliberate, not an oversight.

Verification

Console — npm run typecheck, npm run typecheck:unit, npm run typecheck:e2e all exit 0. npm test: 614 files passed, 1 skipped; 5409 tests passed, 3 skipped, 0 failed. scripts/ci/assert-design-tokens.sh exit 0.

Host — cargo fmt --all -- --check exit 0. cargo clippy --all-targets -- -D warnings exit 0. cargo check --features openhuman,mcp --all-targets exit 0. cargo check --features composio --all-targets exit 0 (run separately because the composio CI lane executes the feature-gated tests this PR adds).

Targeted cargo test --lib composio — 103 passed, 0 failed.

cargo test (full suite) hangs on a pre-existing store::fs race and is therefore not reported green. It stops at store::fs::test::dropping_save_between_its_two_stages_does_not_strand_the_first_temp_file, reproduced twice, test binary asleep at 0% CPU. It is not introduced by this branch: run alone that test passes in 0.05s, the whole store::fs module passes (75 passed; 0 failed; finished in 6.26s), and nothing here touches src/store/. The cause looks structural — stall_probe (src/store/fs.rs:767-812, from #1807) keys its gates by path but signals through a process-global Notify, and six tests share those two globals (:4677, :5505, :5667 on BLOCKED; :4932, :5047, :5192 on COMMIT_BLOCKED), so concurrently-armed stalls cross-signal and notify_one stores only one permit. Being filed separately as a CI flake affecting every branch.

Not verified: nothing here has been seen in a browser, in either theme. That is a gap, not a claim, and it gates this leaving draft.

Draft.

Follow-up: three defects found testing this live (2026-09-12)

Three commits on top of the above, from the operator driving the page in a real browser.

1. "Add a token" looked broken — the credential form is a modal now

45ccb0f5 · frontend/src/composio/rows.ts, frontend/src/views/connections/ComposioSection.tsx

The handler was wired correctly the whole time: the row's button called openForm, composioForm returned a form, and the form rendered — as an inline <Card> appended to the bottom of the section, after the rows, after the "takes effect next turn" line, after two advisory slots. On a scrolling page that put it roughly a screenful below the fold with nothing scrolling to it, so clicking the button moved nothing visible and read as a dead control.

It is a Dialog now, opened from the same four places (Add/Replace on either row, and the own-account row's Use this hand-off). Escape, the backdrop and the X all route through one closeForm, so no exit can leave a pasted secret in state behind a closed modal. A write in flight holds it open, because the dialog is where the host's answer is reported: a rejection renders inside it next to the field (with add anyway, which answers a refused write), while an advisory — the key landed, only the check failed — still renders on the page, since it outlives the dialog that closed on it. credentialDialogTitle / credentialDialogBlurb are pure and in rows.ts with the other decisions; three new unit tests cover them, one of which pins that no title contains the exact phrase "Composio token" — the popup's accessible name comes from that string, and the e2e rotation uses getByLabel(/Composio token/), which would otherwise match both the dialog and the input inside it.

Enter in the field submits, except while the switch confirmation is up.

2. One credential, asked for twice — CompanyCredentialCard is off this page

29955bb3 · frontend/src/views/connections/ComposioView.tsx

The page rendered CompanyCredentialCard (its own paste field and Save for the company's TinyHumans key) directly above ComposioSection, whose managed row reports that same key as "Billed to this company's TinyHumans account". One credential, two surfaces, two visual languages, one page — and nothing telling a reader they were the same thing. Retiring that shape is what this PR is for, so the render call is gone.

Only the render call. The component is unchanged and ApiKeyView.tsx:280 still renders it, so PR #2279 (feat/account-layout) is unaffected.

Consequence worth stating plainly so it is not found later as a regression: HubAccountLinks — the "Manage API keys" and "Top up balance" links out to the TinyHumans dashboard — was rendered by that card, and the rows have no equivalent. Those two links no longer appear on the Composio page. They remain on the API Key page, where the key they act on is set. If they are wanted here too, that is a small follow-up (<HubAccountLinks> takes account and configured), deliberately not invented in this PR.

3. "OpenHuman-managed" → "TinyHumans-managed"

21f452af · rows.ts, ComposioSection.tsx, test/unit/product-scope-hidden-surfaces.test.ts

MANAGED_LABEL, plus the two other user-visible strings on this page that named the same route: the failure toast for "move this company back to managed", and the body of the switch confirmation. managedSubline's per-tier text is untouched — it is what keeps the three-payer distinction the original reasoning was about. The default sub-line for a host that did not say now reads "Reached through the Composio account TinyHumans holds".

test/unit/composio-rows.test.ts asserts through the constant and needed no change; the literal in product-scope-hidden-surfaces.test.ts:275 did.

4. The grant badge is off the Connected heading

44bf12d2 · ComposioSection.tsx

The heading read Connected + a badge saying granted / not granted / grant unknown. Two of those three states are not actionable — "granted" is the ordinary case and "grant unknown" reports that a field was not read — so on nearly every visit it was a chip of tool-namespace vocabulary beside a card about whose Composio account. The third state already has a better home one element below: an explicit not-granted renders GrantNamespace, which says what is wrong in a sentence and offers the fix.

grantStanding and the tri-state stay. The undefined-is-unknown narrowing (#1478) still feeds that call to action; only the badge and the now-unused Badge import are gone.

---

Merge with main, and what the review of it turned up

The conflict

77a4ee22 merges upstream/main. One conflicting file, ComposioSection.tsx, and the two sides did not disagree about anything: main's 5fa2889c7 feat(composio): offer the dashboard the BYOK key comes from is a prettier reflow of the old tile-based component this PR replaces, plus one genuinely new affordance. So the resolution keeps this branch's file and ports that affordance forward: COMPOSIO_DASHBOARD_URL and the Open Composio dashboard outward link (data-testid="composio-open-dashboard"), now inside the credential modal, under the same "From your Composio dashboard at app.composio.dev" line it belongs to.

It is rendered only on the own-account row. The managed route's token is a bearer the TinyHumans backend issues and does not come from app.composio.dev at all, so offering the same errand there would send an operator to the wrong vendor for the credential they were asked for.

CI was red for a reason that predates this branch's last four commits

fcd32fb3 — tests/auth_matrix.rs asserts hardcoded route counts, and b55d23e6 test(auth-matrix): register POST composio/api-key/test added the table row and the 14 snapshot lines but not the counts. Rust (openhuman, tinymemory) failed on table_counts_and_intentional_widenings_are_explicit: left: 189, right: 188. Eight constants bumped, all derived from the one added dual-address admin route: table length 188→189, distinct ops paths 146→147, route-method rows 376→378 and 379→381, concrete rows 427→429, concrete paths 336→338, snapshot lines 2 989→3 003 (checked against wc -l tests/snapshots/auth-matrix.txt), signature-admin rows 60→61.

Findings from a read-through of this branch, and what was done

Both bot reviewers no-op'd on this PR (see the last section), so the diff was read separately. What that turned up:

5f875967 — a stored key whose check failed said nothing at all. settle() set the amber advisory and then called onChanged(), which bumps the generation ComposioView keys this section on — and a changed key is an unmount, so the advisory was discarded before it could paint. The clean branch survived only because toast.success lives outside the tree that remounts. The advisory branch now toasts too (amber, not red: the write landed). The comments that asserted the inline advisory "stays on screen" were false and are rewritten to describe what the page-level slot actually carries — outcomes of the row-level actions, which have no dialog to sit in.

26c2a527 — the authority e2e assertions did not discriminate. Asserting only composio-row-byok-add/replace absent for a member passes for an admin too whenever the company is on the managed route, where the own-account row offers neither. It now asserts every write control on both rows, which is empty for a member on every route. The admin half took .first() over three testids, which on a BYOK company selects the already-checked radio — a deliberate no-op in ComposioRowList — so it now prefers a write control and falls back to [aria-checked="false"] for the hand-off, and asserts the dialog opened.

41f71241 — "add anyway" was offered where it cannot act. skipVerify is a parameter of setComposioApiKey alone; on the managed row's token submit(true) drops it and re-sends an identical request for an identical refusal. Now gated on the form's credential.

00e0c859 — the switch confirmation's ARIA and focus. It carried role="alertdialog" from when it was a block on the page; nested inside DialogContent's role="dialog" aria-modal="true" that is not a composition ARIA defines, so it is a labelled and described role="group". Its focus hand-off was also dead: it recorded the node that had focus, but showing the confirmation is what unmounts that node, so the restore was always skipped on a detached element. It is a ref to the re-rendered Save button now.

494f8316 — three host-side strings on this page still said "OpenHuman-managed". They are toasted verbatim by settle(), so clicking Use this on a row labelled TinyHumans-managed produced a toast saying the company was "back on OpenHuman-managed Composio". BYOK_NOTE, MANAGED_NOTE and the Test route's not-configured message in src/server/ops/composio.rs now say TinyHumans. Doc comments in that file, product-scope.ts, api/composio.ts and the two agent-facing messages in src/harness/built_in/composio_direct.rs still say OpenHuman-managed — none of them reaches this page, and they are left for a sweep that is about the runtime's own vocabulary rather than this surface.

Known, unfixed, and deliberate

• composio-catalog-deadline.spec.ts is still test.skip, so the modal assertion added to it is not exercised. Un-skipping needs a Console E2E lane run.
• A status that moves underneath an open dialog closes it without clearing secret. The dialog is derived from composioForm, which returns null when the rows no longer permit the pending form — that is the point of it — but that path does not run closeForm. Reachable only from a refresh raised behind the overlay; the next openForm clears it. Documented at the function rather than papered over.

Review round, 2026-09-12

Five threads from the Codex reviewer. Each was checked against the code before anything was done about it; two were right and are fixed, three are right about the behaviour but their fix is a host-side decision this PR explicitly took the other way, so those are answered with evidence and left open for the author.

Fixed

160352b7 — the managed route had a dead end. With mode: byok and managedCredentialSource: "none", select is hidden (switching into an outage is not a choice) and addKey was hidden too because it required onManaged — so the route was unreachable in both directions at once, with no way to provision the credential that would create a way in. addKey is now also offered from BYOK in exactly that state. It changes no mode: setComposioToken writes composio/token only, so select appears on the next status read.

160352b7 — COMPOSIO_MANAGED_HIDDEN was not wired to the rows. Its only runtime consumer was onboarding copy, so the documented single-edit kill switch changed the instructions and left every control that acts on the route where it was. It now gates select (and the new BYOK-side addKey). It takes the way in, not the row: a company already on managed keeps its row, because removing the checked option from a radiogroup leaves every remaining radio reporting aria-checked="false" — the a11y regression product-scope-hidden-surfaces.test.ts already pins.

Five tests added; the existing never offers a control on the row a company is not on sweep was narrowed to rotate/remove and now pins that managed/none is the only state where addKey appears on an inactive row.

c02ed0a6 — a token stored for the route a company is not on claimed to be in effect. set_token answered any non-empty value with SWITCH_NOTE ("Agents pick up the new Composio token on their next turn"), which is false for a company still on BYOK — resolve_access reads the BYOK key until the route changes. That state is reachable because of the fix above, so the copy had to catch up: a third note now says the token is saved for the managed route and that agents keep using the current key until the route is switched. The status is read once and both the response and the note are derived from it, so the sentence and the row it ships with cannot disagree.

c02ed0a6 — docs/modules/composio/connect-flow.md still specified "No modal, and why". The component renders one, so the module spec was prescribing the opposite of the implementation. Rewritten, with the original argument quoted rather than deleted: it is right about what a modal holds (there is no catalogue here) and silent about where an inline field lands, which is what actually broke. The section now also records the four consequences that are load-bearing — one exit through closeForm, a refusal inside the dialog, an advisory outside it, and the switch confirmation staying in as a labelled group.

657ff70d — the row badged itself Active while saying nothing worked. Reported off a running build: the managed row wore a green ticked Active beside its own amber sub-line reading "No credential resolves — agents cannot connect apps". active answers "is this the route you picked" and the badge published that as availability, while the tone on the very next line already knew better — two independent truths rendered as one claim.

Both rows now derive a single managedResolves / byokResolves boolean and feed the badge and the tone from it. A route that is selected but resolves to nothing reads Selected, with no tick — the tick is part of the claim, so it is held to the same standard as the word beside it. active stays true: turns really are routed there, and rendering the row as unselected would be the opposite error. ComposioRowList's row.badge ?? "Active" fallback is gone — it quietly restored the exact claim rows.ts had just refused to make — and a sweep test asserts every active row carries a badge, so the fallback is unreachable rather than merely unused. The inference surface settled the same question the same way when its Managed row dropped a permanent "Always on".

Review round, 2026-09-14

3d210282 merges upstream/main @ 892d3d64c cleanly. Then seven threads from Codex and CodeRabbit, all checked against the code before anything changed. All seven were right and are fixed:

• 96968b71 — "Add anyway" was offered after almost any failure. offersSkipVerify unlocked on every rejection but 401/403, and a test pinned the worst case: a failure with no status at all. The spec (connect-flow.md) already said "only after a probe failure". The refusal is now carried with the envelope's code and fromHost, and the offer opens only on the host's own 400 invalid_request, which is what set_api_key returns for a destructive probe class and nothing else. The failure this mattered most for is a 500, which can arrive after the key was stored: the route writes it, then journals and rebuilds status. Offering to add it again invited a duplicate write.
• a96e33fa — the offer survived an edit to the key. A refusal of key A left the offer standing while the operator typed key B, and "Add anyway" then stored B with the probe skipped. Editing the field now retires the refusal. A mounted test covers the sequence.
• ac906d40 — Test was offered on hosts without the check route. The own-account row's Test is now gated on managedCredentialSource being present. git log -S shows it arrived in the same host commit as POST …/composio/api-key/test, and the DTO always serialises it, so its absence means the route is missing and every click would 404.
• a45d258c — the probe's raw upstream error went to the debug log. That text can carry a key fragment, by its own function's doc, and a debug stream is not private. Dropped; the class is still logged.
• eab8f458 — onboarding called the own-account credential a "Composio token". It is a Composio API key; the token is the managed route's override.
• b9f6f13b — onboarding's "Enter a credential in Apps" went to a page with no credential field. Apps has been OAuthView since the Connections split. The no-credential button now goes where the named credential is entered: the API Key page, or the Composio page when the managed route is hidden. It reads the same flag the copy reads.

tinysweeper reviewed the change this round: security read 3 files and critique read 4, both with 0 findings; description and tests also passed.

PR CI Gate (new from #2299) requires every gating lane to pass or skip, so a lane cancelled by a newer push reads as a gate failure on the superseded head. The heads where it went red were superseded; it is only meaningful on the final one.

Answered, open, and for the author to decide

• static cannot distinguish an instance-level TinyHumans key from this company's composio/token. True — TinyhumansTokenSource::source_of_parts reports Static for both — and the consequence is real: Remove token writes an empty override, falls straight back to the same instance key, and reports success while nothing changes. The fix is a slot-specific field on the DTO, and src/server/ops/composio.rs:308-320 says in bold "Do not reintroduce one under any name", with three tests enforcing it. Genuine tension between two different questions — "will Composio work" (the tier) and "is there something here to remove" (the slot) — not something to slip past a written prohibition.
• Selecting the managed route clears the BYOK key. True, and irreversible because credentials are write-only. But the Composio ops router has no mode route (composio.rs:264-277): the host derives the mode from whether a key exists, which is why the own-account row deliberately offers no Remove key. Making the key survive needs a new host route or a PUT …/composio/api-key that separates "deactivate" from "clear". The reviewer cited AGENTS.md:L139-L142 as requiring this; that section is "Documentation Expectations" and says nothing of the kind.
• The 403-plus-credential-wording auth branch is unreachable through a real probe. True — composio_direct.rs:755 returns the status line only, deliberately, because a Composio error body can echo the request and a proxy's is an HTML page. One correction to the severity: an ordinary rejected key comes back 401, which still classifies as auth and is still refused, so this is the narrower 403-rejecting-deployment case rather than "bad keys are stored". Fixing it means the transport classifies internally and returns a class instead of a string.

Also this round

142c1714 merges upstream/main again (#2262's inference rework and #2289). One conflict, tests/auth_matrix.rs, and purely arithmetic: main's table grew by 13 routes and this branch's by 1, so the counts are the sum — 202 routes, 158 distinct ops paths, 404/407 route-method rows, 455 concrete rows, 360 concrete paths, 3 185 snapshot lines (cross-checked against wc -l tests/snapshots/auth-matrix.txt), 71 admin rows. ComposioSection.tsx merged cleanly this time.

b038b020 — the Composio half of connections-authority.spec.ts is gated on COMPOSIO. This is the fix for a red lane, not a convenience. ComposioSection renders nothing when the host lacks the feature (inBuild: false → return null), and Console E2E downloads a --features openhuman,mcp binary — so on that lane there is no credential surface for a member or an admin. Both halves of the spec were wrong there in opposite directions: the member assertion passed for a reason unrelated to authority, and the admin assertion failed outright. That admin assertion is why connections-authority.spec.ts fails on main today. Console E2E (live brain) runs a --features composio host with PW_COMPOSIO=1, and that is where the half is exercised.

Verification

Console — CI. The Console lane (three typechecks, the full vitest suite, both builds, assert-design-tokens.sh) and Console (current Node, advisory) both passed on 44bf12d2. Locally, only the directly affected unit files were run: composio-rows, product-scope-hidden-surfaces, page-section-heading-level, composio-managed-token-card, composio-probe-copy, dialog-width-override, connections-navigation — 7 files, 115 tests, 0 failed.

Host — CI. Rust (mail), Rust (mongodb), Gated host binary and Desktop passed on 44bf12d2; Rust (openhuman, tinymemory) failed there on the route counts and is fixed in fcd32fb3. No cargo was run locally on these commits, by instruction.

Not verified

Nothing here has been seen in a browser, in either theme. That is a gap, not a claim.

Neither automated reviewer actually read this change, and the green checks say otherwise. CodeRabbit posted a rate-limit notice — "You've used all 2 included reviews currently available" — and has no findings on this PR because it never reviewed it. tinysweeper's review check reports success, and its own summaries say Reviewed 0 files; 0 findings. 1 file could not be reviewed: frontend/src/views/connections/ComposioSection.tsx for both security and critique, with description and tests reporting No reviewer could be consulted. Its APPROVED review is therefore not evidence about this code. Read this PR as unreviewed by bots.

Distinguish instance credentials from company tokens

When the managed credential comes from the process-level TINYHUMANS_API_KEY, TinyhumansTokenSource::credential_source() also reports static, even though this company has nothing in composio/token. Treating every static source as managedTokenStored therefore falsely says the token was saved for this company and exposes Replace/Remove controls; Remove only writes an empty company override and immediately falls back to the same process key, so the row remains unchanged despite reporting a successful removal. The status or row derivation needs to distinguish the company-specific token slot from an instance-level static credential.

Useful? React with 👍 / 👎.

[graycyrus]

Confirmed — and not fixed here, because the fix is host-side and reverses a decision this PR took deliberately.

Traced it: resolve_credential (src/company/composio.rs:98) returns the company's composio/token when set and otherwise falls through to company_key::resolve, and RuntimeConfig::credential_source (src/app/config.rs:753) → TinyhumansTokenSource::source_of_parts (src/company/credentials.rs:248) answers CredentialSource::Static for a process-level credential with no token file. So static really does arrive from two different slots, and managedTokenStored = managedSource === "static" in rows.ts cannot tell them apart. Your consequence is right too: Remove token writes an empty composio/token, resolve_credential falls straight back to the same instance key, and the row reports a successful removal while nothing changes.

The host already has the exact primitive — src/company/composio.rs:117 is a function documented as answering "is a non-empty BYO override stored under TOKEN_KEY", with a note saying to use it only where the BYO slot itself is the subject. That is this case. But it is not on ComposioStatusDto: this PR deliberately keeps token and tokenConfigured off the read shape (issue #886) and has a test asserting the exact key set, so putting the distinction on the wire means re-adding a field that was removed on purpose and changing that test.

That is a design call for the author rather than something to slip into a review pass, so I have left this thread open rather than resolving it. Recommendation, for whoever takes it: add a field that names the slot rather than the tier — managedTokenStored: bool sourced from that function — and drive replaceKey/removeKey off it instead of off managedSource === "static". The #886 hazard does not apply, because the question being asked is the one that function is for.

[graycyrus]

Follow-up, because I went looking for whether I could just fix this and the answer is a written instruction not to.

src/server/ops/composio.rs:308-320, the doc on managed_credential_source:

A tier name. Never a credential, never a path, and — the part worth saying out loud — never a boolean about a secret slot. A tokenConfigured-shaped field was on this DTO once and was removed by issue #886 […] Do not reintroduce one under any name. The question it looked like it answered is answered here, by the tier that actually resolves.

So the fix I recommended above — a slot-specific managedTokenStored on the DTO — is the exact thing this comment forbids, and there are three tests asserting tokenConfigured is absent (:1950, :2141, and the key-set sweep at :2847).

I do not think that makes the finding wrong. It makes it a genuine tension: #886 says the resolved tier is the only honest answer to "will Composio work", and this thread shows the slot is the only honest answer to "is there something here to replace or remove". Those are two different questions and the DTO currently carries a field for one of them. Resolving it means either narrowing that prohibition to the question it was written about, or deriving the controls from something else entirely.

Either way it is a call for whoever owns that decision, not something to slip past a comment that says "do not" in bold. Leaving the thread open with that on the record.

Prevent the probe from forwarding keys across redirects

When Composio's /api/v3/toolkits responds with a cross-origin redirect, this client uses reqwest's default redirect policy while putting the draft credential in the custom x-api-key header. That header survives reqwest's cross-origin sanitization—the sibling inference probe documents and guards this exact hazard in src/company/inference/probe.rs:543-551—so merely attempting to save a key can disclose it to the redirect target. Disable redirects or enforce a same-origin redirect policy before sending the credential.

Useful? React with 👍 / 👎.

[graycyrus]

Confirmed real, and not fixed here — it is a credential-disclosure hazard in a shared client path, and I am not shipping an unverified change to that at the end of a long session. Flagging it to the operator as a security item rather than burying it in a thread.

What I checked, so nobody has to re-derive it:

• probe_at (composio_direct.rs:721-733) builds its client with oh::config::build_runtime_proxy_client_with_timeouts("composio.probe", 10, 5) and then sets .header("x-api-key", api_key).
• That helper (vendor/openhuman/src/openhuman/config/schema/proxy.rs:460-490) chains tls_client_builder() → .timeout() → .connect_timeout() → apply_runtime_proxy_to_builder → .build(). There is no .redirect(...) anywhere in it, so reqwest's default applies: follow up to 10 redirects.
• reqwest strips Authorization when the host changes; it does not strip a custom header. x-api-key is a custom header.
• Your citation of the sibling guard is accurate — src/company/inference/probe.rs:543-551 documents this exact hazard in almost these words ("reqwest strips Authorization when the host changes, but it does not strip a custom header … A provider that can answer 302 could therefore hand an operator's Anthropic key to any host it names") and enforces same_origin for both its clients.

Two notes on scope, neither of which softens it:

• It is not only the probe. DirectComposio sends the same header at composio_direct.rs:403 and :557 through the same kind of client, so a fix that covers only probe_at leaves the live path open.
• The base is pinned, so the first hop is always Composio's own host — the exposure needs Composio itself (or anything that can answer for it) to return a cross-origin 3xx. That lowers the likelihood; it does not remove the hazard, and "the upstream would not do that" is not a control.

The fix wants the same shape as the inference one: a same-origin redirect policy, or Policy::none(), applied where these clients are built — which means either a builder-returning variant of that vendored helper or a local one that reapplies the proxy and TLS settings. Both are more than a line, and the second risks silently dropping the proxy configuration the comment at :547 exists to preserve. Worth doing properly and with the Rust lanes watching it.

[graycyrus]

CI note: the one red lane here is not this PR, and I checked rather than assumed.

Console E2E (live brain) fails on connections-authority.spec.ts at

await expect(page.getByTestId("inference-save")).toBeVisible({ timeout: 30_000 });

inference-save does not exist in frontend/src at all. grep -rn "inference-save" frontend/ returns two hits and both are in that spec — the member assertion (toHaveCount(0), which passes vacuously) and the admin one (toBeVisible, which cannot). #2262's inference rework removed the test id and left the assertions behind.

Verified against main itself rather than inferred: on upstream/main @ a20cb3ab the same test fails on the same assertion (line 224 there, 284 here — this branch's additions shifted it). Console E2E and Console E2E (live brain) are both red on main right now at a20cb3ab, 0214e340 and e1494ae7.

What this PR's own commits did to that lane, for the record: the Composio half of the same spec had the identical defect one surface over, and it is fixed here — Console E2E (live brain) is the PW_COMPOSIO=1 lane, so the newly-gated Composio assertions ran there for the first time and passed. 408 tests pass; the single failure is the inference line.

I have not fixed the inference half, deliberately. The right assertion is not obvious from outside that rework: src/inference/ expresses authority by disabling (disabled={!canManage} at ten sites) rather than hiding (one), and the nearest replacement control, inference-own-save (RoutingTab.tsx:266), renders only in one routing mode — so a naive swap would either assert the wrong authority model or depend on the harness company's mode. Guessing at another surface's authority contract is how a spec comes to pin the opposite of what the page means.

Two ways forward, whichever the owners prefer: assert inference-read-only presence/absence, which is the discriminator this spec already uses for MCP and Composio and is mode-independent; or name whatever control #2262 intends to be the admin-only write surface. Happy to do either on a word — it is one small commit in a file I am already in.

Block writes while a credential test is pending

When an admin starts Test on the BYOK row, testingRow disables only the Test button, while this selector and the Add/Replace/Remove controls remain enabled because they check only busy. The test route snapshots the currently stored key before probing it, so the admin can switch to managed or replace the key while that probe is pending; if the old probe then succeeds, runTest emits a global success toast claiming the now-cleared/replaced key was accepted, and other outcomes can likewise describe stale state. Disable credential writes while testingRow !== null, or invalidate the pending verdict whenever a write begins.
