Overview

Syncs the generated spec for the backend's new spend-caps surface (tinyhumansai/backend), and documents a footgun in the sync workflow that this change ran into.

Changes

  • +20 public operations (187 → 207). Two are new here — GET/PUT /spend-caps — plus PUT /api-keys/{keyId}/spend-caps. The remaining 17 are routes already on backend main that the checked-in spec predated: medulla hosts, voice-agent, waitlist, and POST /feedback/validate. They appear because the spec was regenerated from the backend branch's source rather than from production, and the deployed spec is behind main.
  • +4 entries in UNEXPOSED_ROUTES (53 → 57): PATCH /admin/users/{userId}/spend-caps (new), plus GET/PATCH /admin/settings and POST /feedback/admin/triage/{id}/link, which were likewise already on main. The len() pin is bumped with a comment stating it may only ever be reviewed upward — a regenerated spec that stopped describing admin routes would otherwise shrink this list and silently unblock them at the raw transport.
  • AGENTS.md: sync-openapi.mjs defaults to fetching the deployed spec and needs --input when syncing a backend branch that adds routes. A bare run on such a branch regenerates from production and reverts the branch's own routes back out of the SDK. Also records that the input must be the RAW backend document, never the filtered one served at /swagger.json — this script does its own admin/webhook exclusion and derives UNEXPOSED_ROUTES from what it sees, so a pre-filtered input yields an empty denylist and unblocks the very routes it exists to block. Verified directly: the served spec has 0 of the 17 admin paths and 0 of the 13 webhook paths present in the raw document.

Testing

  • cargo test — all suites pass
  • cargo clippy --all-targets -- -D warnings clean
  • cargo fmt --check clean
  • Regenerated via --input from the backend branch's own spec; verified the admin ceiling route adds no public operation and lands in UNEXPOSED_ROUTES

Notes

Both hazards above were hit for real while preparing this change, and the UNEXPOSED_ROUTES.len() pin in src/lib.rs is what caught them. It earns its keep.

Depends on tinyhumansai/backend#1285.

The API specification has been updated to include new endpoints for spend caps, voice agent, waitlist, and additional medulla and feedback operations. The generated public routes file has been updated accordingly, and several webhook routes have been moved from the unexposed list to align with the new API structure.

Auto-committed-on: macbook
Co-authored-by: Medulla <medulla@tinyhumans.ai>
The API specification now reflects 227 paths and 258 total operations, up from 214 and 242 respectively, with the excluded webhook count increasing from 2 to 18. The generated public routes file adds 16 new webhook endpoints to the unexposed routes list, covering services such as Composio, Discord, GitHub, Stripe, and Telegram.

Auto-committed-on: macbook
Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test that asserts the number of unexposed admin and webhook routes is now pinned to 56 instead of 53, with a comment explaining that the count can only be reviewed upward. This prevents a regenerated spec from silently shrinking the list and unblocking those routes at the raw transport layer.

Auto-committed-on: macbook
Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test assertions for operation counts were outdated after the API surface was extended. Updated the expected values for total operations, excluded admin operations, and the corresponding Rust route count to match the current manifest.

Auto-committed-on: macbook
Co-authored-by: Medulla <medulla@tinyhumans.ai>
Removed the spend-caps endpoint group and all admin-only routes from the generated public routes list, as these are internal operations that should not be exposed through the public SDK. The corresponding backend API metadata was also updated to reflect the reduced path and operation counts.

This reverts commit 9346e78.

Co-authored-by: Medulla <medulla@tinyhumans.ai>
The API specification was refreshed to reflect a new endpoint, increasing the path count to 228 and the total operation count to 259. A new admin route for patching user spend caps was added to the list of unexposed routes, ensuring it is properly excluded from public access.

Auto-committed-on: macbook
Co-authored-by: Medulla <medulla@tinyhumans.ai>
The OpenAPI spec was regenerated, adding one new admin route and one new unexposed route. The assertion values in the exclusion and sync tests are updated to match the current spec, keeping the pinning mechanism that prevents silent route changes.

Regenerated from the backend branch's own spec (--input), not the deployed one.
PATCH /admin/users/{userId}/spend-caps is admin-only, so it adds no public
operation and lands in UNEXPOSED_ROUTES to be blocked at the raw transport.

The OpenAPI manifest adds API-key, feedback, Medulla, spend-cap, voice-agent, and waitlist routes. Generated Rust routes and authentication metadata are updated. Route-count tests and the raw transport denylist safeguard now use the expanded totals.

Merge Risk: 🔵 Low · up to 3b4f7

This PR expands the SDK by 20 operations, including spend-cap mutations and a server-to-server voice-agent callback, while the deployed backend document currently lacks the spend-cap routes and some waitlist operations require tokens despite being marked unauthenticated. The change is mergeable with explicit owner awareness: coordinate backend#1285 deployment, confirm callback exposure is intentional, and verify waitlist authentication metadata to avoid 404s or improperly formed requests.

Poem

A rabbit checks the routes in line,
New paths hop in, all neat and fine.
The denylist stands with ears held high,
While manifest counts reach the sky.
Tests thump twice: “The map is right!” 🐇

Exclude the server-to-server voice-agent callback from the public SDK contract.

Add an explicit generator rule for internal customLlmSecret routes, then regenerate api/tinyhumans.backend.json and src/generated_public_routes.rs. PUBLIC_ROUTES does not control raw transport access, so this change corrects the SDK surface contract rather than enforcing authorization.

Heads-up: the content of this PR changed materially after the approval above, so that review is stale.

An earlier regeneration was run against a backend checkout sitting on main rather than the feature branch. The output therefore did not contain the spend-cap routes this PR exists to add, and the pinned counts were lowered to match — UNEXPOSED_ROUTES.len() went to 44, identical to main, which looked like "no change" rather than the regression it was. That is exactly the failure mode the pin is meant to catch, and it only became visible on inspecting the generated files directly.

Regenerated from the feature branch's own spec via --input. Current state, verified against origin/main:

main this branch removed
PUBLIC_ROUTES 202 215 none
UNEXPOSED_ROUTES 44 49 none

Both lists only gain entries. PATCH /admin/users/{userId}/spend-caps is in the denylist; GET/PUT /spend-caps and PUT /api-keys/{keyId}/spend-caps are public.

Two genuine bugs in scripts/sync-openapi.mjs surfaced while fixing this, both now addressed:

  1. isCustomLlmSecretOperation made the script unrunnable. It incremented excludedAdminOperationCount, a const declared further down the function, so every invocation died with a TDZ ReferenceError. The count is derived from excludedOperations regardless, so the increment was redundant — removed. This is why the stale manifest could not simply be regenerated in place.
  2. SUPPLEMENTAL_PUBLIC_OPERATIONS was appended unconditionally. That list exists for operations the deployed document omits. Feeding a local spec that does describe them (team routes, /webhooks/core/*) emitted 9 duplicate routes and tripped generated_rust_routes_match_the_public_manifest. Now skips any entry the spec already covers.

CodeRabbit's customLlmSecret point stands and is implemented: POST /voice-agent/chat/completions moves out of the public surface into UNEXPOSED_ROUTES. I kept that fix SDK-side only. Applying it to the backend's swagger.ts as well would also strip the route from the served public spec — a change to the documented API surface for a route that predates this PR, which belongs in its own change rather than riding along here.

Gates: cargo test (24 suites, 0 failures), cargo clippy --all-targets -- -D warnings, cargo fmt --check — all clean.

Would appreciate a fresh look given the approval predates all of this.
